It all started in the beginnings of 2023, where I started a new course here on dev Titled with: [Nodejs Course 2023](https://dev.to/hassanzohdy/nodejs-course-2023-introduction-to-nodejs-3n4e) that we start building the entire project from scratch.
Every single file there were written during the articles writing time, after achieving a very good progress, "that would be enough" I said to myself for the course.
But it didn't stop there, I started working on imporving the source code by using it in a real project, which was actually my own project [mentoor.io](https://mentoor.io) that's were things were taken to the next level.

### Auto Import Routes 🚗
So basically, the app is divided into modules, each module has its own folder, and inside it, there are controllers, routes, events, mail, models, output, repositories, utils, and validation.
The `routes.ts` file is a special file for each module, it is `auto` imported and called directly, so all you need is to define your routes there.
## Example
Let's see an example of a simple route:
```ts
// src/app/categories/routes.ts
import { router } from "@warlock.js/core";
import { getCategories } from "./controllers/get-categories";
router.get("/categories", getCategories);
```
Here we defined a simple route that listens to `GET /categories` and calls the `getCategories` controller.
Let's create our request handler:
```ts
// src/app/categories/controllers/get-categories.ts
import {
type RequestHandler,
type Request,
type Response,
} from "@warlock.js/core";
import { categoriesRepository } from "./../repositories/categories-repository";
export const getCategories: RequestHandler = async (
request: Request,
response: Response
) => {
const { documents: categories, paginationInfo } =
await categoriesRepository.listActive(request.all());
return response.send({
categories,
paginationInfo,
});
};
```
So basically we called the repository to list our `active` categories where `isActive` is set to `true`
> You can change it in the repository settings to whatever field/value you use in database.
## Request Validation
Validation is as much as simple as it should be, you can define your validation schema in the tail of the request handler
```ts
// src/app/categories/controllers/add-category.ts
import {
type RequestHandler,
type Request,
type Response,
ValidationSchema,
} from "@warlock.js/core";
import { categoriesRepository } from "./../repositories/categories-repository";
export const addCategory: RequestHandler = async (
request: Request,
response: Response
) => {
// using request.validated will return the validated data only
const { name, description } = request.validated();
const category = await categoriesRepository.create({
name,
description,
});
return response.send(category);
};
addCategory.validation = {
rules: new ValidationSchema({
name: ["required", "string", "minLength:6"],
description: ["required", "string"],
}),
};
```
If the validation fails on any rule, it won't reach the controller, and it will return a validation error response.
## A look into the database model
So database models are easy to work with, just define the model, cast the data as it should be there and that's it!
```ts
// src/app/categories/models/category.ts
import { type Casts, Model } from "@warlock.js/cascade";
export class Category extends Model {
public static collection = "categories";
protected casts: Casts = {
name: "string",
description: "string",
isActive: "boolean",
};
}
```
> You don't need to define `id` as the model will auto generate one for each new saved document.
## Data Syncing
One of the powered features of [Cascade](https://warlock.js.org/docs/cascade/getting-started/introduction/) Is [Syncing Models](https://warlock.js.org/docs/cascade/relationships/syncing-models), what does that mean?
Consider we have an `author` for a `post`, that author's data is changed at some point, in that case we need to update the post's author data as well, and that's what syncing models do.
```ts
// src/app/posts/models/post.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { User } from "app/users/models/user";
export class Post extends Model {
public static collection = "posts";
protected casts: Casts = {
title: "string",
content: "string",
author: User,
};
}
```
Now let's define our `User` model, that's where the magic happens:
```ts
// src/app/users/models/user.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { Post } from "app/posts/models/post";
export class User extends Model {
public static collection = "users";
/**
* Sync the list of the given model when the user data is changed
*/
public syncWith = [Post.sync("auth")];
protected casts: Casts = {
name: "string",
email: "string",
};
}
```
So basically, here we are telling the model, when the user's info is updated, find all posts for that author (user) and update the `author` field with the new data.
We can also, conditionally tell the model when to sync the data, for example, we can sync the data only when the user's name is changed:
```ts
// src/app/users/models/user.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { Post } from "app/posts/models/post";
export class User extends Model {
public static collection = "users";
/**
* Sync the list of the given model when the user data is changed
*/
public syncWith = [Post.sync("auth").updateWhenChange(["name"])];
protected casts: Casts = {
name: "string",
email: "string",
};
}
```
Using `updateWhenChange` will only update the post's author when the user's name is changed.
## Models Relationships
Now let's go to the relationships, assume we are going to fetch the post's author when we fetch the post, that's where the relationships come in.
```ts
// src/app/posts/models/post.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { User } from "app/users/models/user";
export class Post extends Model {
public static collection = "posts";
public static relations = {
author: User.joinable("author.id").single(),
};
protected casts: Casts = {
title: "string",
content: "string",
};
}
```
We told the model it is a single relation, and it's joinable by the `author.id` field.
Now when we fetch the post, the author's data will be fetched as well when calling `with` method.
```ts
const post = await Post.aggregate().where("id", 1).with("author").first();
const authorName = post.get("author.name");
```
We may also make the relation as a list, for example, if we have a `post` that has many `comments`:
```ts
// src/app/posts/models/post.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { Comment } from "app/comments/models/comment";
export class Post extends Model {
public static collection = "posts";
public static relations = {
comments: Comment.joinable("post.id"),
};
protected casts: Casts = {
title: "string",
content: "string",
};
}
```
We can also filter comments by passing a query to the `with` method:
```ts
const post = await Post.aggregate()
.where("id", 1)
.with("comments", (query) => {
query.where("isActive", true);
})
.first();
```
This could be useful to filter the data based on the relation, maybe to get comments only for current user,
```ts
import { useRequestStore } from "@warlock.js/core";
const post = await Post.aggregate()
.where("id", 1)
.with("comments", (query) => {
const { user } = useRequestStore();
query.where("createdBy", user.id);
})
.first();
```
Or even we can do it in the relation itself:
```ts
// src/app/posts/models/post.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { Comment } from "app/comments/models/comment";
export class Post extends Model {
public static collection = "posts";
public static relations = {
comments: Comment.joinable("post.id")
.where("isActive", true)
.select("id", "createdBy", "comment"),
};
protected casts: Casts = {
title: "string",
content: "string",
};
}
```
The data will be return as an array in `comments` field, to change the return field name, you can use the `as` method:
```ts
// src/app/posts/models/post.ts
import { type Casts, Model } from "@warlock.js/cascade";
import { Comment } from "app/comments/models/comment";
export class Post extends Model {
public static collection = "posts";
public static relations = {
comments: Comment.joinable("post.id")
.where("isActive", true)
.select("id", "createdBy", "comment")
.as("postComments"),
};
protected casts: Casts = {
title: "string",
content: "string",
};
}
```
To return the comment in a model, call `inModel()` method:
```ts
public static relations = {
comments: Comment.joinable("post.id").where("isActive", true).select('id', 'createdBy', 'comment').inModel(),
};
```

By leveraging a wide array of approaches such as deep learning, neural networks, machine learning, text analysis, and artificial intelligence, predictive analytics transforms raw data into valuable insights, helping enterprises to stay ahead of the curve.
Understanding Predictive Analytics
Predictive analytics involves the process of using historical data to forecast future trends. By analyzing patterns within collected data, organizations can refine their marketing strategies, optimize operations, and improve decision-making processes. This field is closely linked to machine learning, where algorithms learn from historical data to predict future outcomes. Regardless of the method used, the process begins with an algorithm learning from known results, eventually creating a model that can predict future scenarios based on new input variables.
Key Techniques in Predictive Analytics
1. Data Mining
Data mining combines statistics and machine learning to identify anomalies, trends, and correlations within large datasets. This process transforms raw data into actionable business intelligence, revealing current insights and future forecasts that aid decision-making. Exploratory Data Analysis (EDA) is a subset of data mining focused on discovering fundamental properties of datasets using visual techniques, without predefined hypotheses.
2. Data Warehousing
Data warehousing centralizes and integrates data from multiple sources to support business intelligence initiatives. It involves a relational database for storing data, an ETL (Extract, Transfer, Load) pipeline for data preparation, and analysis tools for presenting insights. This foundation is crucial for extensive data mining projects, ensuring that data is organized and accessible for analysis.
3. Clustering
Clustering divides large datasets into smaller subsets based on similarity, creating groups or segments. For instance, customer segmentation based on purchasing patterns allows businesses to tailor marketing campaigns more effectively. Clustering can be hard (direct categorization) or soft (assigning probabilities to clusters), providing flexibility in [data analysis](https://www.sganalytics.com/data-management-analytics/).
4. Classification
Classification predicts the likelihood of an item belonging to a specific category. Common applications include spam filters and fraud detection algorithms. Classification models produce a confidence score, indicating the probability of an observation falling into a particular class, which helps in making accurate predictions and informed decisions.
5. Regression Models
Regression models are used to forecast numerical values. Linear regression, a popular technique, identifies correlations between variables, predicting outcomes such as customer spending based on browsing behavior. These models are essential for understanding relationships between variables and making data-driven predictions.
6. Neural Networks
Neural networks mimic biological systems to predict future values based on historical data. With layers that process inputs, compute predictions, and output results, neural networks are adept at recognizing patterns and are widely used in applications like image recognition and medical diagnostics.
7. Decision Trees
Decision trees graphically represent decision processes, solving classification problems and addressing more complex issues. For example, airlines can use decision trees to determine optimal flight schedules, pricing strategies, and target customer segments, enhancing operational efficiency and customer satisfaction.
8. Logistic Regression
Logistic regression predicts binary outcomes (e.g., success/failure) and can handle multiple relationships without requiring linearity. This model is suitable for predicting probabilities in scenarios where the dependent variable is binary or multiclass, such as determining the likelihood of customer churn.
9. Time Series Models
Time series models forecast future behavior based on past data. Techniques like ARIMA (Auto Regressive Integrated Moving Average) analyze historical data to predict future trends. Time series models can be univariate or multivariate, depending on whether they use past values of a single variable or multiple variables to make predictions.
Applications of Predictive Analytics
Predictive analytics is employed across various industries to enhance decision-making and operational efficiency:
- Creditworthiness Assessment: Financial institutions use predictive analytics to evaluate a person's creditworthiness, enabling informed lending decisions and reducing risk.
- Marketing Strategies: Businesses refine marketing strategies by analyzing customer behavior and predicting future trends, leading to more effective campaigns and increased customer engagement.
- Text Analysis: Predictive analytics predicts the contents of text documents, improving information retrieval and content management systems.
- Weather Forecasting: Meteorologists use predictive models to forecast weather patterns, aiding in disaster preparedness, agricultural planning, and resource management.
- Self-Driving Cars: Autonomous vehicles rely on predictive analytics to navigate safely, using real-time data to anticipate road conditions and traffic patterns.
Conclusion
While predictive analytics has faced criticisms, such as the belief that algorithms cannot predict the future with absolute certainty, its widespread adoption across industries demonstrates its value. By leveraging vast amounts of data, predictive analytics enables organizations to make informed decisions, enhance productivity, and drive growth.
Implementing predictive analytics is crucial for any business seeking to harness the power of data-driven insights. Contact [SG Analytics](https://www.sganalytics.com/) to explore how predictive analytics can transform your business and drive growth.

But have you ever thought about building... | 0 | 2024-06-20T14:31:55 | https://dev.to/aaikansh_22/the-secret-to-rapid-app-development-13c3 | developers, engineer, lowcode, development | We use applications to make our day-to-day tasks easier. But have you ever thought about building applications in the easiest and most efficient way? Here I am talking about the [low-code]() way to build applications within weeks.
Low-code helps everyone build [internal tools](https://www.dronahq.com/building-internal-tools/), admin panels, data dashboards, customer portals, AI-enabled apps, business workflows, process automation, dynamic forms, and many more such use cases.
> By 2025, approximately 70% of new applications created by enterprises are expected to utilize low-code or no-code technologies, a significant increase from the less than 25% recorded in 2020.
**Low-code in easy words;**
Imagine assembling a piece of furniture using pre-cut parts instead of starting from raw wood. Similarly, low-code allows you to focus on fitting components together rather than creating each element from scratch. **The best: It accelerates app development by 10x.**
## **Why focus on low-code?**
For engineering heads and CTOs, low-code platforms are a strategic asset. They integrate seamlessly with existing systems, scale with business needs, and offer robust security features. The reduced time-to-market is particularly compelling; applications that once took months to develop can now be launched in weeks.
For developers, low-code platforms streamline the development process. They provide pre-built templates and reusable components, enabling faster prototyping and deployment. This efficiency allows developers to focus on more complex, high-value tasks rather than getting bogged down in repetitive coding.
> While speaking with TechRepublic Jeffrey Hammond, vice president and principal analyst serving application development leaders at Forrester, thinks **“low-code has the potential to reshape development teams entirely”**.
## **Who can develop with low-code?**
Low-code platforms democratize app development. Frontend developers can easily create user-friendly interfaces, backend developers can handle data integrations, and full-stack developers can streamline the entire process. Even non-developers can contribute, enabling a broader range of team members to participate in the development process.
**Use cases across industries**
Low-code platforms are versatile and can be used across various industries:
**- 1. Healthcare:** Develop patient management systems and telemedicine apps.
**- 2. Retail:** Create inventory management and customer loyalty apps.
**- 3. IT Management:** Build IT service management and asset tracking systems.
**- 4. Manufacturing:** Design production tracking and quality control apps.

The most fundamental difference lies in how they interpret the result of their left expression.
`||` treats its left as a boolean. Regardless of what the left expression is, it ultimately evaluates to either `true` or `false`. This is why, when the left operand is `0`, `''`, `NaN`, `false`, etc., the final result defaults to the right operand.
On the other hand, `??` treats its left expression as a specific value, which can be `null` or `undefined`. This approach allows for more predictable results. As also mentioned in reference [1], `0`, `''`, or `NaN` can also be valid values.

---
[Previously](https://dev.to/ferricoxide/crib-notes-accessing-eks-cluster-with-kubectl-2h1g-temp-slug-7611332), I was worried about, "how do I make it so that `kubectl` can talk to my EKS clusters". However, after several days of standing up and tearing down EKS clusters across a several accounts, I discovered that my `~/.kube/config` file had absolutely _exploded_ in size and its manageability reduced to all but zero. And, while `aws eks update-kubeconfig --name <CLUSTER_NAME>` is great, its lack of a `--delete` suboption is kind of horrible when you want or need to clean out long-since-deleted clusters from your environment. So, onto "next best thing", I guess…
Ultimately, that "next best thing" was setting a `KUBECONFIG` environment-variable as part of my configuration/setup tasks (e.g., something like `export KUBECONFIG=${HOME}/.kube/config.d/MyAccount.conf`). While not as good as I'd like to think a `aws eks update-kubeconfig --name <CLUSTER_NAME> --delete` would be, it at least means that:
1. Each AWS account's EKS's configuration-stanzas are kept wholly separate from each other
2. Reduces cleanup to simply overwriting – or straight up nuking – per-account `${HOME}/.kube/config.d/MyAccount.conf` files
…I tend to like to keep my stuff "tidy". This kind of configuration-separation facilitates scratching that (OCDish) itch.
The above is derived, in part, from the _[Organizing Cluster Access Using kubeconfig Files](https://kubernetes.io/docs/concepts/configuration/organize-cluster-access-kubeconfig/)_ document | ferricoxide |

Para ser um profissional do mercado de tecnologia é necessário desenvolver **hard skills**, que são **ferramentas técnicas** como linguagem de programação, e **soft skills**, que são **habilidades comportamentais** como a comunicação. Ambas as características são essenciais para construção de uma carreira.
## Além das Linhas de Código
**Na rotina de trabalho, a pessoa desenvolvedora irá se comunicar constantemente**, seja de forma síncrona, em reuniões, ou de forma assíncrona, trocando mensagens. É importante transmitir as informações de forma clara e concisa. Escrevemos código para outras pessoas e não apenas para as máquinas.
## Interagindo com Equipes
Outro ponto importante da comunicação é a escuta ativa. Estando verdadeiramente interessado nas ideias ou problemas que estão sendo compartilhados, você poderá entender como auxiliar seu colega de trabalho. Ter essa postura fará com que seus laços sejam reforçados, criando um ambiente seguro e de confiança. **Produtos digitais de sucesso são consequências de grandes times de tecnologia**.
## Documentação Clara, Código Sustentável
Outro momento que a pessoa desenvolvedora se comunica é na hora de criar documentações. **É importante escrever com uma linguagem acessível**, onde qualquer pessoa que tenha acesso ao material possa entender o que está escrito. Dentro de uma empresa, existem pessoas que não possuem conhecimento sobre código, mas devem entender a documentação.
## Resolvendo Conflitos Tecnicamente
**A comunicação eficaz também irá evitar conflitos técnicos na aplicação**. Entender bem qual o problema do negócio e como codificar a solução é essencial para entregar valor. Quando a passagem de informações entre os times de negócio e tecnologia falha em algum ponto, temos riscos de conflitos. E nesse cenário é comum encontrar falhas no produto e consequentemente clientes insatisfeitos.
## Compartilhando Conhecimento
**Atuar como pessoa desenvolvedora vai muito além de trabalhar em uma empresa**, pois podemos compartilhar nossa jornada com a comunidade de tecnologia. Para que outras pessoas aprendam com nossos erros e acertos devemos dispor as informações de forma assertiva, seja sobre assuntos técnicos ou de carreira. Assim podemos aumentar nosso networking, ou melhor, nosso ciclo de amizades. Vejo meus pares da tecnologia como amigos e não apenas como contatos profissionais. Pois amigos estão sempre ao dispor para nos ajudar em momentos difíceis. Só quem já teve a vida transformada por meio da comunidade sabe o que essa frase significa.
Eu saí da minha primeira oportunidade na área em março de 2023. Nessa época estava acontecendo várias ondas de layoffs, demissões em massa, a nível mundial. E como iniciante na tecnologia tive muito medo e insegurança sobre meu futuro. Mas graças aos meus queridos amigos me realoquei um mês depois, em maio já estava na minha segunda oportunidade no mercado.
Graças a comunidade pude continuar vivendo o meu sonho, que é trabalhar como pessoa desenvolvedora. Fui indicada para grandes empresas do setor, dei entrevista para a maior emissora de televisão do país e continuo realizando os meus sonhos e cuidando da minha família. Se você ainda não faz parte da comunidade, comece agora mesmo. Além de uma rede de apoio, você irá aprender com quem já chegou onde você sonha em chegar. **Aprender com a experiência dos outros é uma das grandes dádivas da vida**.

Those basic comparison tools return poor results with many false positives and most completely fail as they use a line-by-line approach, and none offer a solution to the highly complex problem of JSON Merge. However, one API understands JSON object structure and can offer comparison and merge, DeltaJSON, which has an REST API to build into your apps and an easy to use GUI to visualise your JSON.
The DeltaJSON API analyses the object structure together with the content of the data in keys and arrays. Therefore, the comparison or merge is far more accurate at finding differences as it is comparing data regardless of position in the file, avoiding the issues associated with simple line-by-line comparison. The sophisticated algorithms analyse and process the data allowing DeltaJSON to output an accurate result in seconds even with highly complex data.
The importance of structured comparison and merge is most apparent when handling arrays, as data can often move position in an array, which always creates false positives with simple tools. Particularly when subsets of data are held using an array within an array, the output from DeltaJSON is more accurate and cannot replicated with other tools. There are also configuration options for comparing and merging, such as how arrays are processed to consider an array as ordered or unordered pairs.
Configuration of the compare or merge operation is essential to provide flexibility to provide the best result with your objects. The JSON API allows specific control over the type of operation depending to suit the structure of your object. With compare for instance there is control over arrays, and content can be compared as whole text or individual words. Merge operations, in addition to the compare configuration , allows the priority to be set to the A or B document, and which document content should be used for resolution. Finally, with Patch and Graft there is control over the resolution and direction of operation.
Developers and system architects use the compare or merge operation in data migration and integration workflows as a step to find errors prior to committing data. Another use of the output, which can be processed inline as the result is a valid JSON object, is to create an update process removing the need to clear down data and re-import. The benefit being an update is significantly smaller and can be executed in a fraction of the time.
Other use cases include Content Management Systems (CMS) version control and Quality Assurance (QA) for content workflows. However, one of the most compelling use cases is cloud configuration where complex infrastructure managed by JSON is vital to up time and reliability of service provision. DeltaJSON can be used to detect, report and fix configuration changes, managing version control of infrastructure configuration for aspects such as service permissions and infrastructure provisioning.
DeltaJSON is an interesting tool for managing JSON objects which can be built into your code using the REST API. The service is available for free or as a simple annual subscription, with the Professional tier unlocking merge, patch and graft operations together with options for configuration. For simple or complex objects accuracy is important when building into code, and once you start using DeltaJSON you will see a need for its functionality across your applications. | deltajson |

Whether you're a seasoned developer or a newcomer to Salesforce, mastering LWCs can significantly enhance your ability to create dynamic, responsive, and efficient applications. This article aims to provide comprehensive tips and insights into building Salesforce Lightning Web Components, ensuring you can leverage this technology to its fullest potential.
## Understanding Salesforce Lightning Web Components
Lightning Web Components (LWC) are a modern framework for building web applications on the Salesforce platform. They utilize web standards such as custom elements, shadow DOM, and ES6 modules, allowing developers to create encapsulated and reusable components.
## Key Features of LWC
-
**Performance:** LWCs are optimized for performance, with faster load times and efficient data handling.
-
**Standards-Based:** Built on modern web standards, making them future-proof and easier to learn.
-
**Reusable Components:** Components can be reused across different applications, improving development efficiency
## Setting Up Your Development Environment
**Required Tools and Software**
To get started with LWCs, you need the following tools:
-
Salesforce CLI
-
Visual Studio Code (VS Code)
-
Salesforce DX
**Installing Salesforce CLI**
Download and install Salesforce CLI from the official Salesforce website. This tool is essential for creating and managing your Salesforce projects.
**Setting Up Visual Studio Code**
Install VS Code, a lightweight and powerful code editor. Additionally, install the Salesforce Extension Pack to enable Salesforce-specific functionalities in VS Code.
## Creating Your First Lightning Web Component
**Creating Your First Lightning Web Component**
1. Open VS Code and create a new Salesforce project.
2. Use the Salesforce CLI to create a new LWC:
`sfdx force:lightning:component:create --type lwc --componentname myFirstComponent --outputdir force-app/main/default/lwc
`
3. Deploy the component to your Salesforce org using:
`sfdx force:source:deploy -p force-app
`
**Structure of an LWC Project**
An LWC project typically consists of HTML, JavaScript, and CSS files. The HTML file defines the component's structure, the JavaScript file contains the logic, and the CSS file handles the styling.
## Best Practices for Building LWCs
**Code Organization**
Keep your code well-organized by following a consistent folder structure. Group related files together and use meaningful names for components and variables.
**Naming Conventions**
Use clear and descriptive names for your components and variables. Follow camelCase for JavaScript variables and kebab-case for component names.
**Reusability and Modularity**
Design your components to be reusable and modular. Break down complex components into smaller, manageable pieces that can be reused across your application.
## Working with HTML in LWCs
**Basic HTML Structure**
An LWC's HTML file defines its structure. Use standard HTML elements and attributes to build your component.
**Using Standard HTML Elements**
Incorporate standard HTML elements like <div>, <input>, and <button> to build your UI. Use attributes like class and id for styling and identification.
**Customizing with CSS**
Customize your component's appearance with CSS. Define your styles in the component's CSS file, using class selectors to apply styles to specific elements.
## Styling Your Lightning Web Components
**Using CSS in LWCs**
Define your styles in the component's CSS file. Use class selectors to apply styles and ensure your styles are scoped to the component.
**Lightning Design System**
Leverage the Salesforce Lightning Design System (SLDS) to maintain a consistent look and feel. SLDS provides a set of CSS frameworks and guidelines for styling your components.
**Best Practices for Styling**
Keep your styles modular and avoid using global styles. Use SLDS classes where possible and customize styles locally within your component.
## Data Binding in LWCs
**One-Way and Two-Way Data Binding**
Use one-way data binding to pass data from parent to child components. For two-way data binding, use @track and @api decorators to manage state changes within the component.
**Using @api, @track, and @wire Decorators**
-
@api: Exposes properties and methods to parent components.
-
@track: Tracks changes to the component’s state.
-
@wire: Binds a property or function to Salesforce data.
## Handling Events in LWCs
**Creating and Dispatching Events**
Create custom events using the CustomEvent constructor and dispatch them using this.dispatchEvent. This enables communication between components.
**Communicating Between Components**
Use events to communicate between parent and child components. Pass data through events to ensure components remain decoupled and maintainable.
## Testing Your Lightning Web Components
**Unit Testing with Jest**
Write unit tests for your components using Jest, a JavaScript testing framework. Test individual functions and components to ensure they behave as expected.
**Writing Integration Tests**
Use integration tests to verify the interaction between multiple components. Ensure your components work together correctly and handle data properly.
**Debugging Tips**
Use browser developer tools to debug your components. Set breakpoints, inspect elements, and monitor network requests to identify and fix issues.
## Deploying LWCs to Salesforce
**Preparing for Deployment**
Before deploying, ensure your components pass all tests and meet performance standards. Review your code for any issues and optimize where necessary.
**Using Salesforce CLI for Deployment**
Deploy your components using Salesforce CLI:
`sfdx force:source:deploy -p force-app
`
**Post-Deployment Steps**
After deployment, test your components in the production environment. Ensure they work as expected and address any issues that arise.
## Optimizing Performance of LWCs
**Best Practices for Performance**
-
Minimize DOM updates
-
Use efficient data structures
-
Optimize event handling
**Avoiding Common Pitfalls**
Avoid common performance issues like excessive re-renders and memory leaks. Profile your components to identify and resolve performance bottlenecks.
**Profiling and Debugging Performance Issues**
Use browser performance tools to profile your components. Analyze performance data to identify slow operations and optimize them.
## Conclusion
Building Salesforce Lightning Web Components can significantly enhance your development capabilities on the Salesforce platform. By following best practices and leveraging the tips provided in this article, you can create robust, efficient, and maintainable components.

1,894,851 | What is Simulcasting? | Simulcasting, is a short form for the simultaneous broadcasting. This is a process of broadcasting... | 0 | 2024-06-20T14:00:00 | https://www.metered.ca/blog/simulcast-what-is-simulcasting/ | webdev, javascript, devops, webrtc | Simulcasting, is a short form for the simultaneous broadcasting. This is a process of broadcasting the same media content through multiple distribution channels simultaneously
The concept includes streaming the same content across various digital platforms including social media websites, homepage, apps and media sites such as youtube, facebook, linkedIn, Vimeo etc
Previously Simulcating was used in traditional broadcasting to transmit signals in different frequencies and media types
For example in radio transmitting over different frequencies to reach a wider audience or in television transmitting on different TV channels to reach a wider audience
## **How does Simulcast work?**
### **1\. Content Creation**
The first step is the content creation, where the content that is tobe simulcasted is created. This content includes video streams, audio streams and live events etc
### **2\. Encoding**
Once the content is created then the content is encoded, so that it can be transmitted over the internet through different channels. This includes video compression and other converting media into different streaming protocols that are supported
The content is encoded in different formats that are supported by different social media and distribution networks.
### **3\. Distribution**
Once the encoding is done the content is distribution through various social media and content distribution sites. These websites use their own content distribution technologies such as CDNs to distribute the content all across the world
CDN are servers that are located all across the world so that the are nearest to the user who is requesting the content
### **4\. Streaming Protocols**
There are different streaming protocols that are in use by different distribution channels.
These protocols include HLS that is the HTTP Live Streaming and the MPEG-DASH Dynamic Adaptive Streaming over HTTP are popular
These protocols have features like delivering the content in chunks and played over time this helps smoothen out the video over intermittent internet connection
RTMP or Real Time Streaming Protocol is mostly used for high quality streams with low latency such as sports
### **5\. BroadCasting to Multiple Platforms**
As we have already discussed the streams are broadcasted to multiple channels. These channels might include streaming services, social media platforms like youtube, facebook, twitter etc and media channels
### **6\. monitoring and analysis**
When you are simulcasting, it is essential to check the streams performance and analytics to check whether the stream is working properly on all platforms or not
It is also important to check viewer engagement and other metrics on different streaming platforms
## **Benefits of Simulcasting**
There are many benefits of Simulcasting for businesses and content creators and broadcasters
These entities can maximize their reach with simulcasting
### **1\. Expanded audience Reach**
**Geographic expansion:** Simulcasting lets you broadcast on different channels thus allowing you to reach to different geographical locations simultaneously
**Cross Platform Engagement:** Simulcasting allows you to reach audiences that are present on different platforms. Like some people are on YouTube and others are on Facebook
Broadcasting on different platforms allows you to reach audiences that are present on those platforms.
### **2\. Enhanced Viewer experience**
**Accessibility:** Viewers can view the content on their preferred platform thus enhancing the accessibility and improving convenience for viewers
**Resource optimization:** Simulcasting uses the same feed and thus the same content and reaches to a wider audiences thus there is no need to create different content for different distribution channels and thus optimizing the resources for content creation
### **3\. Cost Efficiency**
**Reduction in Operational costs:** Simulcasting the same content to different platforms reduces the cost associated with rendering the content as different platforms use their own technologies to reach the audience and you do not have to create your own distribution network to reach audiences
### **4\. Increased Engagement and Interaction**
**Real time interaction:** Nowadays there are livestreaming on social media platforms and also on live streaming and video streaming services. Simulcasting on all the platforms increases publics real time interaction with your video and you can also create interaction tools with live event chats like [**DeadSimpleChat**](https://deadsimplechat.com/)
**Social Sharing:** People also social share more when there is a buzz created because a lot of public is watching the same content on different platforms and thus people start sharing content for more people to see and thus the media and content gets boosted on social media platforms
### **5\. Improved Content Marketing Strategies**
**Content Repurposing:** Once the Simulcasting is done then the recorded content can also be repurposed to make other contetn like clips and highlights thus driving more engagement from the same content.
## **What is the difference between simulcasting, multicasting and standard streaming?**
### **Simulcasting**
As we have already discussed simulcasting is the broadcasting across multiple distribution platforms or channels. This is like you are simultaneously broadcasting on YouTube, Facebook and other channels
It is used to expand your reach to a broader audience by accessing audiences that are on other channels and as well as expanding reach geographically
### **Multicasting**
Multicasting is the transmission of a stream of video to multiple recipients on a singular network
Unlike Simulcasting where you are targetting multiple channels and websites across the internet, like streaming on youtube, facebook and other platforms simultaneously, multicasting targets a specific group within a network like pay for view sports matches that are only available on certain networks.
### **Standard Streaming**
Standard streaming involves trnasmitting the content from a single source to a single viewer over the internet.
This one to one on demand video transmission is typically followed by YouTube and Netflix where the user demands a video that the platform sends it
## **Types of Simulcast**
### **Video simulcasts.**
Video Simulcasts involve broadcasting video content simultaneously across multiple platforms.
### **Applications**
**Live Events:** Concerts, sports events often use simulcasts to reach wider audiences. These events can also be streamed across social media platforms and streaming services
Webinars and educational content: Educational institutions simulcast tranining sessions to multiple digital platforms to maximize the reach
### **Audio simulcasts.**
Audio simulcasting is the simulcasting of audio broadcasting across multiple platforms, these might include audio platfroms and also traditional media such as radio and modern platforms such as podcasts
### **Hybrid models.**
Hybrid Simulcasts involve a combination of audio and video streams, there are complemented by engagement tools such as chat
There are often used in live events and live streaming events for enagement with audiences.
## **Key Technologies Enabling Simulcasting Streaming protocols (e.g., HLS, RTMP).**
What are streaming protocols, these are rules and standards that are defined and designed to establish how the transmission of video and audio data will be through the internet
These protocols ensure smooth delivery of streaming content to the users, different protocols are designed with different use-cases in mind. Some give low latency but have high bandwidth and cpu requirements, others work with low bandwidths but do have some lag in performance
It is upto you and your use-case which streaming protocol you want to use. Also different streaminh platforms and social media platforms support differnt types of streaming protocols and do not support some other types of streaming protocols
While simulcasting you need to have a knowledge of what streaming protocols are supported by the platforms that you are considering simulcasting on and encode your content in the supported formats.
### **Important or widely supported streaming protocols**
### **HLS (HTTP Live Streaming)**
This protocol was developed by Apple, but it is open source for anyone to use and many platforms use this protocol
**functionality:** HLS breaks the content into smaller chunks and then the device downloads these chunks to create a smooth playback for content
The benefit is that if the device has intermetent connection then when there is connection it quickly downloads the chunks thus smoothing out the playback event in choppy internet
Also, the client has the choice of streams, the client device can select the stream according to its own bandwidth and CPU capacity
HLS you can submit different streams in order to give client devices a choice as to which stream to subscribe to according to their bandwidth and CPU requirements
HLS is widly supported and a good choice for different network conditions
### **RTMP (Real Time Messaging Protocol)**
RTMP was developed by Adobe and it is also open source and anyone can use it.
RTMP is a TCP based protocol which maintains constant connection with the client devices in order to provide low latency streaming. these kinds of streaming is good for sports and other activities
RTMP can stream audi video and data over the internet, RTMP can encapsulate MP3, ACC and various other audio and video formats
RTMP is ideal for live streaming which cannot be done through HLS because HLS has a latency issue

## Demo
{% embed https://youtube.com/shorts/9JtRjGBUdzo %}
# Screenshots
## Twilio and AI
I leveraged Twilio’s **Voice API**, **phone number** validation, and OpenAI’s text generation capabilities to create an integrated solution for sending personalized voice messages. Here’s how it works:
- **Message Generation**: Users input their message or use the app to generate a random message using OpenAI. This ensures that even users who are unsure of what to say can send meaningful messages.
- **AI Voice Generation**: The app uses PlayHT to convert the text message into a natural-sounding voice message. There is support for normal and cloned voices for even more fun.
- **Phone Number Validation**: Before sending the message, the app uses Twilio’s Lookup API to validate the recipient’s phone number, ensuring that messages are sent to valid numbers.
- **Twilio Integration**: The generated voice message is uploaded to Firebase, and a URL is generated. Twilio’s Voice API is then used to make a call to the recipient, playing the voice message.
By integrating Twilio’s capabilities, the app ensures reliable and clear communication, making each celebration special and memorable.
## Additional Prize Categories
• **Twilio Times Two**: The app extensively uses Twilio’s Voice API to deliver voice messages and the Lookup API for phone number validation.
• **Impactful Innovators**: By making it easier to send personalized celebration messages, the app helps people stay connected and celebrate important moments despite physical distances.
• **Entertaining Endeavors**: The integration with OpenAI and PlayHT (normal and parody voices) to generate random and fun messages adds an element of surprise and entertainment for users.
## Further Notes
- Currently using Twillio sandbox account (not tested it live)
- Apple sign in with firebase
- Scheduled celebrations cloud functions (future work)
- More cloned voices (future work)
- Redesign (I'm not a designer, so future work)
- Privacy and Firebase App Check and api's lifted to the cloud (future work)

1,894,853 | Design Pattern #3 - Observer Pattern | Continuing our quest into trending design patterns for front-end developers, we follow up our first... | 27,620 | 2024-06-20T13:57:55 | https://www.superviz.com/design-pattern-3-observer-pattern-for-frontend-developers | javascript, architecture, learning, webdev | Continuing our quest into trending design patterns for front-end developers, we follow up our first article [on the Singleton pattern](https://dev.to/superviz/design-pattern-1-singleton-for-frontend-developers-14p9) with a look at [the Facade pattern](https://dev.to/superviz/design-pattern-2-facade-pattern-1dhl) in this second piece. Now we will dive into the observer pattern.
## Observer pattern
The Observer pattern is an easy-to-understand, and widely used messaging design where an object, called the subject, maintains a list of its dependents, called observers, and notifies them automatically of any state changes. This promotes a loose coupling between related objects and allows for efficient communication between them.
### Real case scenario
Consider a Customer and a Store. The customer wants a new iPhone model not yet available in the store. They could check daily, but most trips would be unnecessary. Alternatively, the store could spam all customers whenever a new product arrives, saving him them from pointless trips but annoying others. This creates a dilemma: either the customer wastes time or the store wastes resources.
### The observer pattern solution
In the example above, the Customer is the observer while the Store is the subject. The Customer may want to receive updates on a specific category of products, or not, giving it the possibility of choosing what it wants to observe.
In that case, the the Store (i.e., the subject) knows who is interested in its updates (the Customer, or observer), and there can be many Customers. Various Customers can sign up for updates from the same Store, and all will receive notifications whenever a new product is added.
This communication can occur every time a new product is created, updated, or removed in the Store.
Even though the Store knows who its Customers are in the Observer pattern, it doesn't concern itself with or know what each Customer will do with the updates received. Each Customer has complete control over what to do with the updates they receive.
Another pattern that looks really similar to the observer is the Publisher/Subscriber pattern, that I will cover on the next post of the series.
## Code example
If you are like me, you want to see the code, it makes it simpler to understand, so here's a simple JavaScript code example illustrating the Observer pattern:
```jsx
// Define a class for the Provider
class Store {
constructor() {
this.observers = [];
}
// Add an observer to the list
add(observer) {
this.observers.push(observer);
}
// Notify all observers about new product
notify(product) {
this.observers.forEach(observer => observer.update(product));
}
}
// Define a class for the Observer
class Customer {
update(product) {
console.log(`New product added: ${product}`);
}
}
// Usage
const store = new Store();
const customer = new Customer();
store.add(customer); // Add a customer to the store's observers
store.notify('iPhone 15'); // Notify all observers about a new product
```
In the code above, the Observer pattern is exemplified through the creation of two classes, `Store` and `Customer`.
The `Store` class represents the provider (some people may call it the subject). It has an array `observers` that stores all the observers (`Customer` instances) that are interested in updates from the `Store`. It also has an `add` method to add a new observer and a `notify` method to notify all the observers about a new product.
While the `Customer` class represents the observer, it has an `update` method that do some action when it receives the update, in this case it logs on the console.
All set, let’s use it. So we create a`Store` and a `Customer` object. The `Customer` is added to the `Store`'s observers using the `add` method.
Then, the `Store` notifies all its observers (in this case, just one `Customer`) about a new product ('iPhone 15') using the `notify` method. The `customer.update()` method is called, and it logs the new product to the console.
That’s it! Now you have one more design pattern on your skill arsenal. Stay tuned for more exploration into different design patterns in this series, and let me know in the comments what design pattern you would like to see next! | vtnorton |

Artificial Intelligence (AI), once a distant dream, is now a vital part of our daily lives. From smartphones that recognize our faces to virtual assistants who know just what we need, AI is everywhere. But what's truly exciting is how AI is revolutionizing entire industries, remaking the way businesses operate and innovate.
And, did you know that by this year, AI is expected to power 90% of new enterprise apps in the United States? This staggering statistic highlights the critical role AI is bound to play in our future. So, what can AI development services do for your business or industry? This blog aims to unlock the mysteries and potentials of AI development, guiding you through its benefits, challenges, and immense possibilities.
Are you ready to dive into the world of AI and explore how it can propel your business into a new era of efficiency and innovation? Let’s get started!
## What exactly are AI development services?
In simple terms, they are the array of techniques and processes used to create and implement artificial intelligence solutions that can perform tasks traditionally requiring human intelligence. These services aren't just about crafting sophisticated software; they're about creating systems that learn, adapt, and potentially even think.
### Key Components of AI Services
1. **Machine Learning (ML):** At the heart of AI is machine learning, where algorithms learn from and make decisions based on data. Imagine a system that not only learns from its mistakes but also gets smarter with each one!
2. **Natural Language Processing (NLP):** Ever chatted with Siri, Alexa, or any chatbot? That's NLP in action. It enables machines to understand and interact with human language, turning everyday language into actionable commands.
3. **Robotics:** When AI meets mechanical engineering, you get robotics. These are not just the manufacturing arms you might see in a car plant; they're also the rovers exploring Mars and automated systems in your smart home.
## Benefits of Implementing AI Development Services
Implementing AI development services brings a multitude of advantages that can transform the way businesses operate and interact with their customers. Let's dive into some of these benefits and see how they can make a significant impact.
### Automation of Repetitive Tasks
Are you tired of spending countless hours on mundane tasks that seem to eat up all your productive time? AI is here to rescue you from drudgery. By automating repetitive tasks, AI allows you and your team to focus on more creative and strategic activities. Whether it's data entry, scheduling appointments, or generating reports, AI can handle these tasks faster and with fewer errors. Imagine a workplace where your energies are spent on innovation and growth rather than routine tasks. That's the power of AI!
### Enhanced Decision-Making Through Data-Driven Insights
In a complex business environment, making decisions based on gut feelings isn't enough. AI enhances decision-making by providing data-driven insights. This means you can make informed decisions quickly and with greater accuracy. AI analyzes vast amounts of data to spot trends, predict market changes, and provide actionable insights that are not visible to the human eye. With AI, businesses can anticipate customer needs, optimize operations, and stay ahead of the competition.
### Improved Customer Experience Through Personalized Services
What if every customer felt like your service was tailor-made just for them? AI makes this possible through personalization. From personalized shopping recommendations on e-commerce sites to customized content on streaming platforms, AI helps businesses tailor their offerings to match individual preferences. This not only enhances customer satisfaction but also increases loyalty and sales. AI’s ability to learn from customer interactions means that personalization only gets better over time, continually improving the customer experience.
### Cost Reduction and Operational Efficiency
AI is a powerhouse when it comes to boosting operational efficiency and reducing costs. By streamlining processes and automating tasks, AI helps businesses operate more efficiently, which in turn reduces overhead costs. For example, AI can optimize supply chains, predict maintenance needs before they become costly repairs, and even handle customer service inquiries without human intervention. These efficiencies can lead to significant cost savings, making businesses more agile and competitive.
## Industries Transformed by AI Development Services
AI development services are not just a technological upgrade; they are revolutionizing entire industries, reshaping them from the ground up. Here’s a closer look at how AI is making waves across various sectors:
### Healthcare: Diagnostics, Patient Care, and Management
In healthcare, AI is playing a critical role in saving lives and enhancing patient care. Advanced algorithms are being used to diagnose diseases with a level of accuracy that rivals, and sometimes surpasses, human experts. AI-driven diagnostic tools can analyze medical images, detect anomalies, and even predict the likelihood of diseases such as cancer earlier than ever before. Beyond diagnostics, AI is also personalizing patient care with treatment plans tailored to individual genetic profiles and managing entire healthcare systems by optimizing schedules, reducing wait times, and managing patient flow. This integration of AI is not just improving outcomes; it's changing the patient experience by making healthcare more accessible and efficient.
### Finance: Fraud Detection, Risk Assessment, and Algorithmic Trading
The finance industry has embraced AI to secure transactions and enhance financial operations. AI systems analyze patterns in vast datasets to identify unusual behavior that could indicate fraud, helping institutions prevent losses before they occur. Risk assessment models powered by AI can evaluate the creditworthiness of clients more accurately and much faster than traditional methods. Moreover, algorithmic trading uses AI to execute trades at optimal prices, analyze market data, and make split-second decisions that maximize investor returns. This AI-driven approach helps financial institutions stay ahead in a highly competitive market.
### Retail: Customer Behavior Analysis and Inventory Management
AI is reshaping the retail landscape by offering insights into customer behavior and streamlining inventory management. Through AI, retailers can track shopping patterns, predict trends, and provide customers with personalized recommendations based on their browsing and purchasing history. This level of personalization enhances the shopping experience and boosts customer loyalty. On the inventory side, AI helps retailers optimize their stock levels, predict demand, thereby reducing overstock and understock situations. It ensures that capital is not tied up unnecessarily and that customers find what they want when they visit.
### Manufacturing: Predictive Maintenance and Supply Chain Optimization
Manufacturing has seen one of the most significant impacts of AI, particularly in predictive maintenance and supply chain optimization. AI systems can predict when a machine is likely to fail or when maintenance is due, preventing costly downtime and extending the lifespan of equipment. AI enhances supply chain efficiency by optimizing logistics, predicting potential disruptions, and suggesting the best routes and methods for supply chain operations. These improvements not only save time and money but also increase the efficiency of manufacturing processes. It leads to higher productivity and reduced waste.
## Challenges in AI Development
While the benefits of AI are extensive, the path of AI development comes with its own set of challenges. These hurdles are crucial for businesses to understand and address to fully harness the potential of AI technology.
### Data Privacy and Security Concerns
One of the most pressing issues in AI development is ensuring the privacy and security of data. AI systems require vast amounts of data to learn and make decisions. This raises significant concerns about how data is collected, used, and stored. Providing the confidentiality of sensitive information and protecting against data breaches are paramount. Organizations must adhere to strict data protection regulations, such as [GDPR in Europe](https://gdpr-info.eu/), and implement robust cybersecurity measures to safeguard user data, a complex but essential step in maintaining trust and integrity in AI systems.
### High Initial Investment and Integration Complexities
Deploying AI technology often requires a substantial initial investment, which can be a barrier for many businesses, especially small and medium-sized enterprises (SMEs). The cost includes not only the technology itself but also the infrastructure needed to support AI systems. Integrating AI into existing business processes can be complex and disruptive. Organizations must carefully plan the integration process, often requiring customized solutions and significant changes to existing workflows, which can add to the cost and complexity.
### Shortage of Skilled AI Professionals
The demand for skilled AI professionals far exceeds the supply, posing a significant challenge for the development and implementation of AI solutions. Specialized knowledge in areas such as machine learning, data science, and AI algorithm development is crucial, yet there is a global shortage of experts in these fields. This gap can delay development projects and increase costs as companies compete for talent. Investing in education and training programs to nurture a new generation of AI professionals is essential for the sustainable growth of AI technologies.
### Ethical Considerations and Bias in AI Algorithms
AI systems learn from data, and if that data contains biases, the AI's decisions will reflect those biases. This can lead to unfair or unethical outcomes, such as discrimination in hiring practices or lending. Addressing these issues requires a deliberate effort to ensure the data used to train AI systems is representative and free of biases. Moreover, ethical considerations must be at the forefront of AI development, necessitating guidelines and standards to make sure AI systems operate fairly and transparently.

1,894,848 | The Data Professions | With the development of Machine Learning, new professions have emerged. There are eight main roles,... | 0 | 2024-06-20T13:49:39 | https://dev.to/moubarakmohame4/the-data-professions-30e | data, datascience, dataengineering, datastructures | With the development of Machine Learning, new professions have emerged. There are eight main roles, in addition to more traditional positions like project manager or developer. These roles help form a team capable of managing a project from start to finish. Creating models is certainly important, but it is not enough. It is also necessary to be able to deploy and maintain applications, requiring a wide range of different skills.
These professions are divided into three branches:
- A "model" oriented branch
- An "integration" oriented branch
- A "support" oriented branch
1. In the "model" branch, the first role is the **Data Analyst**. Their primary task is to prepare and format data, either to extract Key Performance Indicators (KPIs) directly or to inject the data into Machine Learning algorithms. They can also provide dashboards and possess skills in data visualization.
2. The second role is the **Data Scientist**. Their task is to create models from the prepared data. This role requires strong knowledge in mathematics and statistics as well as programming skills, mainly in R or Python. The Data Scientist role is often seen as an evolution of the Data Analyst role, either through specialized training or with on-the-job experience, though the skill sets do not completely overlap between the two positions.
In the "integration" branch, there are three roles. Their purpose is to enable models to interact with more complex IT systems. Their roles range from data input retrieval to result output and model retraining.
1. The first role is the **Data Architect**. Similar to the Solution Architect (in more traditional IT), their task is to create an architecture that allows all elements to interact together, but focused on data flow. Knowledge in Big Data is often necessary due to the volumes handled (skills in Spark and Hadoop are sought after).
2. The second role is the **Data Engineer**. Their task is to implement the architecture defined by the Data Architect. This requires good programming and process automation skills. The Data Architect also needs to understand this technical aspect to create high-quality architectures.
3. The third role is the **Data Integrator**. Their task is to ensure that data can transition from one system to another, in the correct format and with the right syntax. This role requires knowledge in data buses, middleware, and data transformation.
A sixth role, increasingly mentioned in literature and articles, is the **Machine Learning Engineer**. This is a Data Engineer trained in Data Science and Machine Learning or a Data Scientist who has learned programming.
Finally, in the "support" branch, two new roles have emerged. Their task is not to execute projects but to support other roles and the project once in production.
1. The first role is **Data Support**. This is a helpdesk with added data project skills, allowing them to monitor models and act quickly when a problem arises. The more models in production, the more crucial their role becomes in ensuring service continuity.
2. The **Data Steward**, on the other hand, is a project manager with additional data skills. Since Machine Learning projects cannot be managed in the same way as more traditional development projects, adapted project management is necessary. Their role includes discussing with clients, estimating the remaining work, ensuring good communication among all team members, and, in large projects, managing the parallel progress of various roles.
Most of these professions did not exist a few years ago, and many more are likely to emerge in the coming years, which will inevitably change the scope of each of these roles. Similarly, as technologies evolve very rapidly, individuals working in these various professions must continuously follow developments and undergo training. Without this ongoing learning, they risk quickly finding themselves with outdated skills. | moubarakmohame4 |

After all, the higher the... | 0 | 2024-06-20T13:46:24 | https://dev.to/darlangui/understanding-solid-c2g | solidprinciples, learning, agile, rust | Quality of software is the fundamental basis for developing any system. After all, the higher the software quality, the fewer errors there are, and it facilitates maintenance and the addition of new functionalities in the future.
Simply put, software quality can be said to be inversely proportional to the incidence of errors.
With this in mind, various studies and approaches have been developed to increase software quality.
Among these approaches, the beloved or dreaded SOLID emerged.
But what is SOLID, exactly?
SOLID is an acronym that represents five principles that facilitate the development process, making the code cleaner, separating responsibilities, reducing dependencies, facilitating refactoring, and promoting code reuse, thereby increasing the quality of your system.
These principles can be applied in any object-oriented programming (OOP) language.
## S - Single Responsibility Principle
In simple terms, this principle states that **"Every class should have one, and only one, reason to change"**, which is the essence of the concept.
This means that a class or module should perform a **single task**, having responsibility only for that task.
For example, when you first started learning object-oriented programming, you probably encountered classes structured like this:
```rust
struct Report;
impl Report{
fn load(){}
fn save(){}
fn update(){}
fn delete(){}
fn print_report(){}
fn show_report(){}
fn verify(){}
}
```
> Note: This is in Rust. In Rust, there is no concept of classes; instead, we use structures like `struct` and `traits` to achieve this kind of behavior. However, the implementation and explanation of *SOLID* are also possible in this language.
We can see that in this example, we have the `struct Report` (which in other languages would be a class) and it implements several methods. The issue isn't with the number of methods per se, but rather that each of them does completely unrelated things, causing the `struct` to have more than one responsibility in the system.
This violates the Single Responsibility Principle, causing a class to have more than one task and thus more than one responsibility within the system. These are known as _God Classes_ — classes or structs that do everything. Initially, this might seem efficient, but when there's a need to change this class, it becomes difficult to modify one responsibility without affecting the others.
**_God Class_** — *In object-oriented programming, it's a class that knows too much or does too much.*
Breaking this principle can lead to lack of cohesion, as a class shouldn't take on responsibilities that aren't its own, as well as creating high coupling due to increased dependencies and difficulty in code reuse.
- **Lack of cohesion**:
- A class shouldn't take on responsibilities that aren't its own.
- **High coupling**:
- Due to increased responsibilities, there's a higher level of dependencies.
- **Difficulty in code reuse**:
- Code with many responsibilities is harder to reuse.
We can fix that code simply by applying the Single Responsibility Principle:
```rust
struct Report;
impl Report {
fn verify(){}
fn get_report(){}
}
struct ReportRepository;
impl ReportRepository {
fn load(){}
fn save(){}
fn update(){}
fn delete(){}
}
struct ReportView;
impl ReportView {
fn print_report(){}
fn show_report(){}
}
```
By doing this, you ensure that each struct/class has a single task, in other words, only one responsibility. Remember that this principle applies not only to structs/classes, but also to functions and methods.
## O - Open-Closed Principle
This acronym is defined as **_"software entities (such as classes and methods) should be open for extension, but closed for modification"_**. This means you should be able to add new functionalities to a class without altering the existing code. Essentially, the more features we add to a class, the more complex it becomes.
To better understand, let's consider a `struct` for a Shape:
```rust
struct Shape {
t: String,
r: f64,
l: f64,
h: f64,
}
impl Shape {
fn area(&self) -> f64 {
if self.t == "circle" {
3.14 * self.r * self.r
} else {
0.0
}
}
}
```
To add the identification of a rectangle, a less experienced programmer might suggest modifying the existing `if` structure by adding a new condition. However, this goes against the Open-Closed Principle, as altering an already existing and fully functional class can introduce new bugs.
So, what should we do to add this new task?
Essentially, we need to build the function using an interface or a `trait`, isolating the extensible behavior behind this structure. In Rust, it would look like this:
```rust
trait Shape {
fn area(&self) -> f64;
}
struct Circle {
radius: f64,
}
impl Shape for Circle {
fn area(&self) -> f64 {
3.14 * self.radius * self.radius
}
}
struct Rectangle {
width: f64,
height: f64,
}
impl Shape for Rectangle {
fn area(&self) -> f64 {
self.width * self.height
}
}
```
With this approach, we can add various other shapes without modifying the existing code.
This is the Open-Closed Principle in action, making everything cleaner and simpler to analyze, if necessary, in the future.
The key is that each new shape implements the `Shape` trait with its own `area` method, allowing the system to be extended with new shapes without modifying existing implementations. This promotes software extensibility and minimizes the risk of introducing errors into already tested and functional code.
This way, we can keep the code organized and reduce the impact of future changes, facilitating system maintenance and evolution.
## L - Liskov Substitution Principle
This principle has the following definition: **_"Derived classes (or child classes) must be able to substitute their base classes (or parent classes)"_**. In other words, a child class should be able to perform all actions of its parent class.
Let's dive into a practical example to better understand:
```rust
struct Square {
side: f64,
}
impl Square {
fn set_height(&mut self, height: f64) {
self.side = height;
}
fn set_width(&mut self, width: f64) {
self.side = width;
}
fn area(&self) -> f64 {
self.side * self.side
}
}
fn main() {
let mut sq = Square { side: 5.0 };
sq.set_height(4.0);
println!("Area: {}", sq.area());
}
```
In this case, the square directly breaks this rule because the `trait` states that both height and width can be different, which is not valid for a square.
So, what can we do in this case? It's simple:
```rust
trait Rectangle {
fn set_height(&mut self, height: f64);
fn set_width(&mut self, width: f64);
fn area(&self) -> f64;
}
struct Square {
side: f64,
}
impl Square {
fn set_side(&mut self, side: f64) {
self.side = side;
}
}
impl Rectangle for Square {
fn set_height(&mut self, height: f64) {
self.set_side(height);
}
fn set_width(&mut self, width: f64) {
self.set_side(width);
}
fn area(&self) -> f64 {
self.side * self.side
}
}
fn main() {
let mut sq = Square { side: 5.0 };
sq.set_height(4.0);
println!("Area: {}", sq.area());
}
```
Now, the square adheres to the Liskov Substitution Principle because it respects the `trait` rules of the Rectangle. This is just one example of how this rule applies.
### Examples of LSP Violation:
- Overriding/implementing a method that does nothing.
- Throwing an unexpected exception.
- Returning values of types different from the base class.
To avoid violating this principle, it's often necessary to use dependency injection, along with other principles from SOLID itself.
With this, you can see how these principles connect and complement each other as you understand how they work.
## I - Interface Segregation Principle
Simply put, the Interface Segregation Principle states that a class should not be forced to implement interfaces and methods it doesn't use. In other words, we shouldn't create a single generic interface.
Let's move on to a practical example to better understand:
```rust
trait Worker {
fn work(&self);
fn eat(&self);
}
struct Human;
impl Worker for Human {
fn work(&self) {}
fn eat(&self) {}
}
struct Robot;
impl Worker for Robot {
fn work(&self) {}
fn eat(&self) {} // robos comem????
}
```
In this example, we have an interface (trait) `Worker` that requires classes implementing it to have two methods: `work` and `eat`. It makes sense for the `Human` class to implement these two methods, as humans work and eat. But what about `Robot`? A robot works but does not eat. Therefore, it is forced to implement the `eat` method even though it's not necessary.
How can we fix this? The answer is to create specific interfaces.
```rust
trait Workable {
fn work(&self);
}
trait Eatable {
fn eat(&self);
}
struct Human;
impl Workable for Human {
fn work(&self) {}
}
impl Eatable for Human {
fn eat(&self) {}
}
struct Robot;
impl Workable for Robot {
fn work(&self) {}
}
```
There we go, problem solved! Now we have two distinct interfaces: `Workable` and `Eatable`. Each one represents a specific responsibility. The `Human` class implements both interfaces, while the `Robot` class implements only the `Workable` interface.
By adopting specific interfaces, we avoid forcing classes to implement unnecessary methods, keeping the code cleaner, more cohesive, and easier to maintain. This is the essence of the Interface Segregation Principle, which helps create more flexible and robust systems.
## D - Dependency Inversion Principle
This principle has two explicit rules:
- High-level modules should not depend on low-level modules. Both should depend on abstractions.
- Abstractions should not depend on details. Details should depend on abstractions.
What does this mean? Simply put: depend on abstractions, not on implementations.
Let's move on to a practical example to better understand:
```rust
struct Light;
impl Light {
fn turn_on(&self) {
println!("Light is on");
}
fn turn_off(&self) {
println!("Light is off");
}
}
struct Switch {
light: Light,
}
impl Switch {
fn new(light: Light) -> Switch {
Switch { light }
}
fn operate(&self, on: bool) {
if on {
self.light.turn_on();
} else {
self.light.turn_off();
}
}
}
fn main() {
let light = Light;
let switch = Switch::new(light);
switch.operate(true);
switch.operate(false);
}
```
We can see that the `Switch` class depends entirely on the `Light` class. In this case, if we need to replace the `Light` class with a `Fan` class, we would also have to modify the `Switch` class.
How do we solve this? Depend on abstractions, not on implementations, following the principle:
```rust
trait Switchable {
fn turn_on(&self);
fn turn_off(&self);
}
struct Light;
impl Switchable for Light {
fn turn_on(&self) {
println!("Light is on");
}
fn turn_off(&self) {
println!("Light is off");
}
}
struct Fan;
impl Switchable for Fan {
fn turn_on(&self) {
println!("Fan is on");
}
fn turn_off(&self) {
println!("Fan is off");
}
}
struct Switch<'a> {
device: &'a dyn Switchable,
}
impl<'a> Switch<'a> {
fn new(device: &'a dyn Switchable) -> Switch<'a> {
Switch { device }
}
fn operate(&self, on: bool) {
if on {
self.device.turn_on();
} else {
self.device.turn_off();
}
}
}
fn main() {
let light = Light;
let switch_for_light = Switch::new(&light);
switch_for_light.operate(true);
switch_for_light.operate(false);
let fan = Fan;
let switch_for_fan = Switch::new(&fan);
switch_for_fan.operate(true);
switch_for_fan.operate(false);
}
```
Now, `Switch` depends on the abstraction `Switchable`, and both `Light` and `Fan` implement this abstraction. This allows `Switch` to work with any device that implements the `Switchable` interface.
### Benefits:
- **Flexibility**: Adding new devices that implement `Switchable` is easy without needing to change the existing `Switch` code.
- **Maintenance**: Changes in specific device behaviors do not affect the control logic.
- **Decoupling**: Reduces coupling between high-level and low-level modules, making testing and parallel development easier.
## Conclusion
By applying the SOLID principles, you can make your software more robust, scalable, and flexible, easing modification without much hassle or difficulty.
SOLID is essential for developers and is often used in conjunction with Clean Code practices to further enhance system quality.
While understanding these concepts and examples may seem daunting at first, it's important to remember that we may not always apply all these principles during development. However, with practice and persistence, you can write increasingly mature and robust code. SOLID will be your guide on this journey.
If you want to delve deeper with illustrations, I recommend watching this video by Filipe Deschamps:
- [SOLID Made EASY with These Illustrations (Portuguese)](https://www.youtube.com/watch?v=6SfrO3D4dHM&t)
If you've read this far, I strongly encourage you to start implementing these principles in your projects, as there's no better way to learn programming than by: PROGRAMMING.
Thank you for reading!

Los modelos de ML, especialmente los basados en redes neuronales profundas, son vulnerables a varios tipos de ataques y fallos que pueden comprometer su fiabilidad. Este artículo aborda las técnicas avanzadas para mejorar la seguridad y robustez de estos modelos.
**Ataques Adversariales**
Uno de los mayores desafíos en la seguridad de ML son los ataques adversariales. Estos ataques implican introducir perturbaciones imperceptibles a las entradas del modelo para manipular sus predicciones. Para mitigar estos ataques, se emplean varias técnicas:
_Entrenamiento Adversarial:_ Este método entrena al modelo con ejemplos adversariales generados durante el entrenamiento, mejorando su capacidad para resistir ataques. La idea es exponer al modelo a ejemplos perturbados para que aprenda a reconocer y manejar entradas adversariales.
_Defensa Basada en Detección:_ Involucra el uso de modelos secundarios para identificar y filtrar entradas adversariales antes de que lleguen al modelo principal. Estos modelos pueden ser redes neuronales entrenadas específicamente para detectar patrones sospechosos en los datos de entrada.
**Robustez Certificada**
La robustez certificada se refiere a la capacidad de un modelo para garantizar su comportamiento bajo ciertas perturbaciones.
Lo anterior se logra mediante el uso de métodos formales que proporcionan garantías matemáticas sobre el rendimiento del modelo:
_Métodos de Propagación Intervalar:_ Utilizan intervalos para representar incertidumbres en los datos y propagan estas incertidumbres a través de la red para obtener límites sobre las salidas del modelo. Esto permite certificar que el modelo es robusto dentro de ciertos límites de perturbación.
_Pruebas Basadas en Satisfacibilidad:_ Emplean técnicas de satisfacibilidad booleana (SAT) y programación lineal entera (ILP) para verificar que el modelo no cambia sus predicciones bajo perturbaciones específicas.
**Regularización y Técnicas de Entrenamiento**
Las técnicas de regularización y entrenamiento mejorado también contribuyen a la robustez de los modelos:
_Regularización de Peso:_ Penaliza la complejidad del modelo para evitar sobreajuste y mejorar la generalización. Esto se puede hacer mediante técnicas como la regularización L2 o el dropout, que añaden ruido durante el entrenamiento para robustecer el modelo.
_Normalización de Datos:_ La normalización y estandarización adecuadas de los datos de entrada pueden mejorar la estabilidad del modelo frente a perturbaciones.
**Evaluación de Robustez**
Evaluar la robustez de un modelo es crucial para entender sus limitaciones y fortalezas. Se utilizan varias métricas y métodos de evaluación:
_Evaluaciones Basadas en Perturbaciones:_ Involucran probar el modelo con datos perturbados y medir su rendimiento para diferentes grados de perturbación.
_Análisis de Sensibilidad:_ Examina cómo pequeñas variaciones en los datos de entrada afectan las predicciones del modelo.
En resumen, mejorar la seguridad y robustez de los modelos de aprendizaje automático es esencial para su aplicación en escenarios críticos. Mediante técnicas como el entrenamiento adversarial, la robustez certificada, la regularización y la evaluación rigurosa, podemos desarrollar modelos más resistentes a ataques y perturbaciones, garantizando su fiabilidad y seguridad.

It allows users to interact with your React... | 0 | 2024-06-20T13:38:34 | https://dev.to/chariesdevil/how-to-handle-user-input-in-a-react-native-application-3dpf | User input is the lifeblood of most mobile applications. It allows users to interact with your React Native app, providing data and instructions that drive the functionality. Here's a deep dive into handling user input effectively in your React Native projects:
**Core Component: TextInput**
The primary component for text input in React Native is TextInput. It offers a versatile way to capture user-typed information. Here's a breakdown of its key features:
Controlled vs. Uncontrolled Components: React Native favors controlled components for text input. This means the component's state manages the current value displayed, and any changes are reflected through event handlers.
**Props:**
value: The current text displayed in the input field.
onChangeText: Function triggered whenever the text changes, taking the new text value as a parameter.
placeholder: Placeholder text displayed when the input field is empty.
keyboardType: Sets the keyboard type (e.g., default, numeric, email-address).
secureTextEntry: Enables password masking with dots.
Many more for styling and behavior customization (refer to official documentation: https://reactnative.dev/docs/textinput)
Example of Handling Text Input with TextInput:
import React, { useState } from 'react';
import { View, TextInput, Text } from 'react-native';
const MyInput = () => {
const [inputText, setInputText] = useState('');
const handleChange = (text) => {
setInputText(text);
};
return (
<View>
<TextInput
value={inputText}
onChangeText={handleChange}
placeholder="Enter your name here"
/>
<Text>You entered: {inputText}</Text>
</View>
);
};
export default MyInput;
**This example demonstrates a basic text input with:**
useState hook to manage the inputText state variable.
value prop of TextInput set to the current inputText state.
onChangeText prop calls the handleChange function whenever the text changes.
handleChange updates the inputText state with the new text value.
A text display showing the currently entered text.
**Beyond Text Input:**
**While TextInput excels at text input, React Native offers other options for user interaction:**
Buttons: The Button component allows users to trigger actions. You can define onPress events with functions to handle button clicks.
Switches: The Switch component enables users to toggle between two states (on/off).
Pickers: The Picker component provides a dropdown menu for users to select options from a predefined list.
Sliders: The Slider component allows users to select a value from a continuous range using a visual slider bar.
Touchable Components: Components like TouchableOpacity, TouchableHighlight, and TouchableWithoutFeedback allow capturing user touches on various UI elements, enabling custom interactions.
**Event Handling for User Input:**
Most user input components provide event props to capture user actions. These props typically follow the format on<Event>, where <Event> refers to the specific user interaction (e.g., onPress, onChange).
Within the event handler function, you can access the user's input data and perform necessary actions:
Update component state based on user input.
Trigger API calls to send or retrieve data.
Perform calculations or validations on user input.
**Form Handling:**
For complex scenarios involving multiple input fields, consider using libraries like react-native-forms or building custom form components. These libraries help manage form state, validation, and submission.
**Advanced Techniques:**
Validation: Implement validation logic within event handlers to check the validity of user input before processing it further. You can display error messages or prevent invalid submissions. (Consider libraries like yup for validation)
Debouncing: For actions that don't require immediate updates on every keystroke (e.g., searching), debounce user input events to prevent excessive API calls or UI updates. (Use libraries like lodash/debounce)
Accessibility: Ensure user input components are accessible for users with disabilities. Utilize props like accessibilityLabel and follow accessibility guidelines for React Native development.
**Security Considerations:**
Sanitize User Input: Always sanitize user input before processing it to prevent potential security vulnerabilities like injection attacks.
Password Masking: Ensure passwords are masked with dots using secureTextEntry for TextInput.
Data Validation: Validate user input to prevent unexpected behavior or security risks. | chariesdevil | |
1,894,809 | Deploy ReactJs website on Apache server (Hostgator) with Vite | Why on earth deploy to Apache/Hostgator? To see if it works. That simple. And does it... | 0 | 2024-06-20T13:34:41 | https://dev.to/luiztux/deploy-reactjs-website-on-apache-server-hostgator-with-vite-jl6 | ## Why on earth deploy to Apache/Hostgator?
To see if it works. That simple.
And does it work? Of course it works, but it needs a few things to make it work properly.
## Let's go from the beginning
It's a simple website, but it will be in a subfolder. For example:
`https://mydomain.com/site2`
Having defined this, chances are that you use a Router (react-router-dom, TanStack Router, etc.). I use react-router-dom a lot, so this case is no different.
## Configs
### package.json
As the website will be in a subfolder, you need to add the `homepage` tag to your `package.json` file, otherwise the build will assume that your project is hosted in the root of the server.
```js
{
...
"homepage": "https://mydomain.com/site2/",
...
}
```
### BrowserRouter config
Add the `basename` prop to the BrowserRouter:
```js
import { BrowserRouter } from 'react-router-dom';
import { Router } from './routes/Router';
export const App = () => {
return (
<BrowserRouter basename='/site2'>
<Router />
</BrowserRouter>
)
}
```
### vite.config.js
Without this step, no matter what you do, when you run `vite build`, the generated `index.html` file will have the wrong link references. Therefore, this configuration is crucial.
All you need to do is add the `base` option in the `vite.config.js` file:
```js
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
// https://vitejs.dev/config/
export default defineConfig({
base: '/site2/',
plugins: [react()],
})
```
Or via the `vite build --base=/my/public/path/` flag.
Finally, just run the build. In my case, I use `pnpm`:
```bash
pnpm run build
```
### Configuring Apache
Right. But for all of this to work online, you still need to configure Apache, using the `.htaccess` file.
**You need to have this file in the folder where the index.html will be located**. Therefore, create the file in the folder, in my case, `/site2`, with the following content:
```apache
RewriteEngine On
RewriteBase /site2
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.html [L]
```
Finally, upload the files from your project's `dist` folder to your Apache folder. Don't forget the files in the `assets` folder.
That's it! | luiztux | |

In today's digital age, many of us find ourselves spending long hours seated at desks, staring at computer screens. While these sedentary jobs are common, they can take a toll on our physical health if we're not careful. The good news is, with a few simple adjustments to our daily routines, we can maintain our physical health and well-being even while working at a desk job.
**Take Regular Breaks:** One of the most important things you can do to combat the effects of a sedentary job is to take regular breaks. Set a timer to remind you to stand up, stretch, and move around every hour. Even a short break can help improve circulation, reduce stiffness, and prevent muscle fatigue.
**Incorporate Activity into Your Day:** Look for ways to incorporate movement into your everyday schedule. Take the stairs instead of the elevator, walk or bike to work if possible, and use your lunch break to go for a short walk outside. Every little bit of movement counts and can help counteract the effects of sitting for long periods of time.
**Practice Desk Exercises:** You can also perform simple exercises right at your desk to keep your body moving throughout the day. Try doing leg lifts, shoulder rolls, and neck stretches to help alleviate tension and improve flexibility. You can find plenty of desk exercise routines online that are designed specifically for office workers.
**Use a Standing Desk:** Consider investing in a standing desk or a desk converter that allows you to alternate between sitting and standing throughout the day. Standing desks can help reduce the amount of time you spend sitting and may even improve posture and reduce the risk of certain health issues like back pain and obesity.
**Stay Hydrated:** Drinking plenty of water is essential for overall health, but it's especially important when you have a sedentary job. Carry a water bottle at your desk and make a conscious effort to drink water throughout the day. Staying hydrated can help prevent dehydration, headaches, and fatigue, and it may even help boost productivity.
**Practice Good Ergonomics:** Pay attention to your workstation setup and make sure it's ergonomically designed to support good posture and reduce strain on your body. Adjust your chair, keyboard, and monitor to ensure they are at the proper height and distance from your body. Using an ergonomic chair or adding a lumbar support cushion can also help maintain proper alignment and reduce discomfort.
**Mindful Eating:** Lastly, pay attention to your eating habits while at work. It can be easy to mindlessly snack on unhealthy foods when you're busy, but making conscious choices about what you eat can have a big impact on your overall health. Pack nutritious snacks like fruits, vegetables, nuts, and yogurt to keep at your desk, and try to avoid sugary drinks and processed foods.
In conclusion, while working a sedentary job can present challenges to maintaining physical health, it's entirely possible to stay healthy with some simple adjustments to your daily routine. By taking regular breaks, incorporating movement into your day, practicing desk exercises, using a standing desk, staying hydrated, practicing good ergonomics, and mindful eating, you can support your physical well-being and feel your best even while working at a desk job. Remember, small changes can add up to big benefits over time, so start implementing these strategies today for a healthier tomorrow.

1,894,814 | The Fool's Journey (through AWS) | Tarot Tarot cards are sometimes used as a form divination, but they are historically based... | 0 | 2024-06-20T13:09:44 | https://dev.to/aws-builders/the-fools-journey-through-aws-52c0 | aws, awscommunitybuilder | ## Tarot
Tarot cards are sometimes used as a form divination, but they are historically based on several suits or Arcana. Although you can study Tarot for quite a while and come up with different ways of interpreting a reading of Tarot, in Cartomancy Tarot the "main" suits, or Major Arcana, tell a life's journey. Numerically, the "0" or first card in the journey is called the Fool.
##The Fool
The Fool, contrary to English colloquialism, doesn't represent idiocy or stupidity, but rather ignorance. We all begin as a fool in life, lacking experience or going through the other Arcana. Indeed, most journeys start with a total lack of knowledge, but not a lack of common sense or will. The Fool starts the journey.
Your AWS cloud journey will start the same way and go through the various Major Arcana as you climb to total AWS knowledge - a literally impossible task, but a goal to strive for nonetheless. In tarot, this last step is known as The World. With the World, you have all the knowledge and experience possible. Quite a grand goal in life, let alone on your AWS journey.
(It should be noted that there are different interpretations of the cards, in various languages, and that I will mostly stick to the Rider-Waite terms, but in some, the World may be known as the Universe but have similar interpretations)
Going through all 22 Major Arcana and what they mean for your journey would be a book onto itself, but I'd like to highlight some places you will go and show you that it is definitely okay.
##The Magician
The first card after the Fool in is the Magician. The Magician itself can represent a few things, but the focus here is on potential. The Magician represents focused potential in the field, and this is where everyone starts.
It doesn't matter if you've never opened a bash shell before or if you're able to do subnetting in your sleep. Every cloud journey begins with potential and having it focused on AWS learning is important.
Some tips to get started into The Magician step of your journey is to commit to a goal, whether it's attaining a certification (such as the Cloud Practitioner), doing a specific task (such as setting up a blog), or simply measuring your knowledge (such as teaching a friend about what you learned). This helps your potential have a solid focus which lets your journey begin.
##The Emperor
The fifth card is called the Emperor. The Emperor represents authority and structure, which is a hard thing to accept on your journey. AWS specifically makes it a bit easier, as they offer white papers and blogs on specific topics or how things are supposed to be done, but accepting the "how things are done" step is important. Eventually, you might have a good reason to deviate from authority, but at this phase of your journey, learning, knowing, and following best practices is critical. For example, AWS recommends using accounts to isolate workloads. Instead of having all your cloud functions in one shared account, this isolation protects other workloads (in what is usually referred to as "blast radius"). Violating this best practice can lead to major issues when something starts to blow up or mutate over time and creates a potentially risky or fragile structure.
##Strength
Strength Arcana, the 12th one, represents something a little different and something we all want - a success. Eventually, in your journey, you will overcome a series of obstacles and eventually deploy a project to production.
Enjoy it! It's a beautiful moment when you can see your work live, whether it's a certification, a website you can click on, watching metrics as others use what you've built, or something between. Your first major success is an incredibly fulfilling moment, knowing your journey has led there.
Personally, I recall deploying an EKS Cluster on AWS (back when EKS was still in preview!) and putting my first confluent control plane on it. Years and many deployments later, I still remember the moment an application did it's first message in a queue on the Kafka setup I deployed. It's an incredible step on your journey and one you should hold tightly to on your journey - but acknowledge your journey is far from done. One success does not unlock all AWS knowledge to you!
##Temperance
Temperance, the 15th Arcana, can be about many things, but primarily about moderation. At some point, you will architect beautiful, stable designs, following best practices and show them to reviewers that will complain about expense, cognitive load, engineering overhead, or straight up complexity. Even though your design is probably the ideal one for a theoretical situation and solution, it will need to be tempered by frugality, both fiscal and labor, as well as moderation of usage.
I've seen a number of web-based services use EC2 as their primary engine when ECS or even Lambdas would be a more elegant and faster solution. However, it will come to a point that the cost of an EC2 instance is worth it to an organization to reduce the engineering labor. Perhaps they have an excellent patching policy and don't yet have an understanding of how serverless truly works and worry about noisy neighbors or having their data left behind for another function to scoop up. There are also times where we might want a good service over another good one - such as leveraging Bedrock's models instead of making your own with SageMaker, but the fear of Generative AI forces usage of SageMaker instead.
On my journey, I spent a lot of time in Temperance, and honestly, probably come back to it the most for when I talk about the journey most people take. Don't expect to rush through your journey, the experience is more important than becoming the perfect architect or engineer. After all, journey before destination.
##The Tower
Coming in at number 17, the Tower is an Arcana that represents upheaval or trouble. Eventually, you will own a solution and it will fail. Perhaps it simply goes down or failover fails or a malicious actor breaks it. Regardless of how it happens, your design will one day fail because you didn't consider something. This usually happens once you're more senior and can own complex architectures and designs.
This step in the journey is not one unique to your cloud journey, either. There's always the ongoing joke that you aren't a senior developer until you've taken down production environments. However, this is also the greatest learning experience on your journey - not only learning about why your implementation failed, but also learning how those around you act. What happens if your design broke something serious enough to involve a C-level officer or Legal? How the people interact with your failure is just as important, perhaps more, than your cloud service's failure.
The Tower is also one of the most stressful as it can lead to being removed from a project or being let go from a job. This is not the end of the journey! You not only can, but must learn how to recover from trouble to continue down the path you want to walk. The focus you learned during the Magician step of your journey should help you persist through the Tower, but it is never easy.
##The Star
The Star, the 19th Arcana, is where I feel I am at - it represents hope and opportunity. As you walk your journey, there eventually comes a time where you've built the previous Arcana and what you've learned from them to a bright spot. Opportunities happen, whether they are careers or others, such as being an AWS Community Builder. It is here that you can truly hold great titles in Cloud and work on complex and overwhelming projects with success and deliver to expectations to others around you and also your self-held expectations.
The Star is an exciting part of your journey and one to definitely enjoy. I am not sure how long I will be on the Star step - hopefully longer than Temperance! - but I have yet to understand when you're stepping to the next part of the journey.
##Beyond the Star
This is where I leave you.
There is more to learn and more things that need to happen with me to keep growing through the journey. Everyone's journey - yours, mine, your colleagues, your friends, everyone's - will be different. Perhaps you will move faster than I did. Or slower. Maybe you will have your great failure earlier than anyone else, but perhaps you will have years and years before the Tower calls for you. You don't really know until you get there.
In summary, your journey will have many steps and many things to learn at each juncture. There are upsides and downsides along the way, but they all build you to be a better engineer or architect.
##Special Thanks

JavaScript is an ever-evolving language, and one of its more intriguing features is generators. Generators provide a powerful way to handle asynchronous programming, making your code cleaner and more manageable. This article will take you through the ins and outs of JavaScript generators with detailed, step-by-step examples to help you master this feature.
## What Are JavaScript Generators?
Generators are a special type of function that can be paused and resumed, making them perfect for handling asynchronous operations. They use the `function*` syntax and yield values using the `yield` keyword.
### Example of a Basic Generator Function
Let's start with a basic example to understand how generators work.
```javascript
function* simpleGenerator() {
yield 1;
yield 2;
yield 3;
}
const gen = simpleGenerator();
console.log(gen.next()); // { value: 1, done: false }
console.log(gen.next()); // { value: 2, done: false }
console.log(gen.next()); // { value: 3, done: false }
console.log(gen.next()); // { value: undefined, done: true }
```
In this example, `simpleGenerator` is a generator function that yields three values. Each call to `gen.next()` returns an object with the `value` and `done` properties. The `done` property indicates whether the generator has finished executing.
## Advanced Generator Usage
Generators can do more than just yield simple values. They can also receive input and handle errors.
### Sending Values to a Generator
You can send values back to the generator using the `next` method.
```javascript
function* interactiveGenerator() {
const name = yield "What is your name?";
const age = yield `Hello, ${name}. How old are you?`;
return `Your name is ${name} and you are ${age} years old.`;
}
const gen = interactiveGenerator();
console.log(gen.next().value); // "What is your name?"
console.log(gen.next("Alice").value); // "Hello, Alice. How old are you?"
console.log(gen.next(30).value); // "Your name is Alice and you are 30 years old."
```
In this example, the generator asks for a name and age, which are then used to generate a final message. This demonstrates how generators can be interactive, pausing to wait for input.
### Handling Errors in Generators
Generators can also handle errors using the `throw` method.
```javascript
function* errorHandlingGenerator() {
try {
yield 1;
yield 2;
yield 3;
} catch (e) {
console.log("Error caught: ", e);
}
}
const gen = errorHandlingGenerator();
console.log(gen.next()); // { value: 1, done: false }
console.log(gen.next()); // { value: 2, done: false }
gen.throw(new Error("Something went wrong")); // Error caught: Error: Something went wrong
console.log(gen.next()); // { value: undefined, done: true }
```
Here, the generator handles an error thrown from outside, allowing for graceful error handling within the generator function.
## Generators and Iterators
Generators implement the iterator protocol, making them compatible with any construct that uses iterators, like `for...of` loops.
### Using Generators with for...of Loops
```javascript
function* countDownGenerator(start) {
while (start > 0) {
yield start--;
}
}
for (const value of countDownGenerator(5)) {
console.log(value);
}
// Output: 5, 4, 3, 2, 1
```
This example shows a generator counting down from a given number, demonstrating how generators can be seamlessly integrated with `for...of` loops.
## Asynchronous Programming with Generators
One of the most powerful uses of generators is in asynchronous programming. They can simplify the handling of asynchronous operations.
### Using Generators for Asynchronous Operations
Generators, in combination with a runner function, can be used to manage asynchronous code more elegantly.
```javascript
function* asyncGenerator() {
const data1 = yield fetch("https://jsonplaceholder.typicode.com/posts/1").then(res => res.json());
console.log(data1);
const data2 = yield fetch("https://jsonplaceholder.typicode.com/posts/2").then(res => res.json());
console.log(data2);
}
function run(generator) {
const iterator = generator();
function iterate(iteration) {
if (iteration.done) return;
const promise = iteration.value;
promise.then(x => iterate(iterator.next(x))).catch(err => iterator.throw(err));
}
iterate(iterator.next());
}
run(asyncGenerator);
```
In this example, `asyncGenerator` fetches data from two different URLs. The `run` function handles the promises, resuming the generator when each promise resolves. This approach avoids deeply nested callbacks and makes the code more readable.
## FAQs About JavaScript Generators
### What Is the Difference Between Generators and Regular Functions?
Generators can pause and resume their execution, whereas regular functions run to completion once called. This makes generators useful for managing asynchronous operations and complex iteration logic.
### Can Generators Be Used for Infinite Sequences?
Yes, generators are well-suited for creating infinite sequences because they can yield values indefinitely without exhausting memory.
```javascript
function* infiniteSequence() {
let i = 0;
while (true) {
yield i++;
}
}
const gen = infiniteSequence();
console.log(gen.next().value); // 0
console.log(gen.next().value); // 1
console.log(gen.next().value); // 2
// This can continue indefinitely
```
### How Do Generators Improve Code Readability?
Generators improve readability by breaking complex operations into smaller, manageable steps. This is especially beneficial in asynchronous programming, where generators help avoid "callback hell."
### Are There Performance Considerations When Using Generators?
Generators can introduce a slight overhead compared to regular functions due to their ability to pause and resume execution. However, this overhead is usually negligible compared to the benefits they provide in terms of code clarity and maintainability.
## Conclusion
Mastering JavaScript generators can significantly enhance your coding skills, especially in handling asynchronous operations and complex iteration scenarios. By understanding the basics, exploring advanced usage, and leveraging generators for asynchronous programming, you can write cleaner, more manageable code.
Generators are a powerful feature in JavaScript that can simplify many programming tasks. With practice and thoughtful application, they can become an invaluable tool in your development toolkit. | chintanonweb |
1,894,832 | Optimizing Image Loading with AVIF Placeholders for Enhanced Performance | It's no secret that page load times have a big impact on user experience, bounce rates, and... | 27,791 | 2024-06-20T13:24:53 | https://dev.to/lilouartz/optimizing-image-loading-with-avif-placeholders-for-enhanced-performance-556b | webdev, performance, beginners | It's no secret that page load times have a big impact on user experience, bounce rates, and SEO.
Meanwhile, some of the Pillser pages load a lot of data, e.g.,
* [https://pillser.com/brands/absolute-nutrition](https://pillser.com/brands/absolute-nutrition) (13 products)
* [https://pillser.com/brands/21st-century](https://pillser.com/brands/21st-century) (215 products) (takes a few seconds to load)
(The topic of why I am not using pagination is for another day.)
Therefore, I need to squeeze out every last bit of performance to maximize the user experience.
## LQIP
Low Quality Image Placeholder (LQIP) is a technique that allows us to serve a low quality placeholder image to the browser while the actual image is being loaded.
Example:
The challenge though is that because the image needs to be visible immediately, we need to inline the actual image in the HTML, i.e. every bit counts towards the page size.
Here is what it looks like for the image above:
```html
<div style="border: 1px solid #eee; width: 320px; aspect-ratio: 2469/1606; background-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAXCAMAAABd273TAAAAIGNIUk0AAHomAACAhAAA+gAAAIDoAAB1MAAA6mAAADqYAAAXcJy6UTwAAAC0UExURfz///v///j8//r+//b6/fP3+vL2+fX5/PT4+/f7/vH1+O/z9vD09/n9/+zw8+ru8e3x9Ovv8u7y9ent8Ofr7uTo6+Pn6uXp7Obq7eDk597i5d/j5tzg49vf4t3h5OHl6Nnd4Nfb3tXZ3NTY29PX2tre4ejs79ba3dLW2c/T1s3R1M7S1dDU19jc39HV2MzQ08nN0MjMz8rO0cvP0sXJzMTIy8fLzsbKzcPHysLGyeLm6f///w5wCeoAAAABYktHRDs5DvRsAAAACXBIWXMAAAsSAAALEgHS3X78AAAAB3RJTUUH6AYUDCQTGrRfOwAAAAFvck5UAc+id5oAAAIZSURBVCjPTZLrdqowEIVTrXeLVRAEEsi14ZKEm4LH93+wM9rV1ebXXsle32T2DEIIvc1mc/Q8b++L5WL2kmi+Wqx/5Ga12rwc8/V2t119mzfL/Xb9AeJjA7e77Xo2n8/WO+/gbd+/3z8Px9Ni9oa2O88PAt/bL5d7LziHkX9ab2ar/fFyBrlcoSAK4ySJw8D3g3OKSZYH3n5/8sMEZ/nleEIJpoxzRpI8TwkTkqs0+vIvOWZcq/QcIC2KsqqNYEpZ7uqqFDQNw5jowjiukhyZumm7rq8LzoVp2nYwmqQptkXdVE6TBDVDd73dxqEsClf149RWkuJMcTP0A9AwGtrpdr9PfW0cAKapqwpLMBV1D1hpya/BOVP9GIiVVTu2VcEIanooce2ghHR1P8KtfBqKqpu6xjGF6qrvxrGvnIB2hu6bq5gbxuvUG26RK6u+bRsjtX518TQopU1/vV/bUjAkIYahgS6t1UU9tPB1qygv29u/e1dLjbhwZf0Miiomy2ZoDKdE/TEwLZ0xhaaEUEgSWFph8ipxgxIWwSQKVwhLsowAojSCZklGi2a8jsOzTWW1kFLTLE0zCl7JSJrHmJcQVAmpIwII8TtNASMMozClsm5KQeIzwsRqrimOH484o0xb2IKvywPDNKVNIx9lgNBMZXl4fqTEWtiBr4MfpZQLjUP/ExZGWWZJ8jjDamEKqOjgHYOcACyJvN1/yWxdxmlLsYwAAAC0ZVhJZklJKgAIAAAABgASAQMAAQAAAAEAAAAaAQUAAQAAAFYAAAAbAQUAAQAAAF4AAAAoAQMAAQAAAAIAAAATAgMAAQAAAAEAAABphwQAAQAAAGYAAAAAAAAASAAAAAEAAABIAAAAAQAAAAYAAJAHAAQAAAAwMjEwAZEHAAQAAAABAgMAAKAHAAQAAAAwMTAwAaADAAEAAAD//wAAAqAEAAEAAAAgAAAAA6AEAAEAAAAXAAAAAAAAAB72jjsAAAAldEVYdGRhdGU6Y3JlYXRlADIwMjQtMDYtMjBUMTI6MzY6MTkrMDA6MDApQGkQAAAAJXRFWHRkYXRlOm1vZGlmeQAyMDI0LTA2LTIwVDEyOjM2OjE5KzAwOjAwWB3RrAAAACh0RVh0ZGF0ZTp0aW1lc3RhbXAAMjAyNC0wNi0yMFQxMjozNjoxOSswMDowMA8I8HMAAAAVdEVYdGV4aWY6Q29sb3JTcGFjZQA2NTUzNTN7AG4AAAAgdEVYdGV4aWY6Q29tcG9uZW50c0NvbmZpZ3VyYXRpb24ALi4uavKhZAAAABN0RVh0ZXhpZjpFeGlmT2Zmc2V0ADEwMnNCKacAAAAVdEVYdGV4aWY6RXhpZlZlcnNpb24AMDIxMLh2VngAAAAZdEVYdGV4aWY6Rmxhc2hQaXhWZXJzaW9uADAxMDAS1CisAAAAF3RFWHRleGlmOlBpeGVsWERpbWVuc2lvbgAzMoisZxcAAAAXdEVYdGV4aWY6UGl4ZWxZRGltZW5zaW9uADIzOya/RQAAABd0RVh0ZXhpZjpZQ2JDclBvc2l0aW9uaW5nADGsD4BjAAAAAElFTkSuQmCC);background-size:100% 100%"></div>
```
This LQIP has been generated using [ThumbHash](https://evanw.github.io/thumbhash/). Compared to other implementations of LQIP (like BlurHash or Potato WebP), this one encodes more details in the same space.
However, the above image representation still consumes 2,050 bytes of data, which adds up to ~440 KB for a page with 215 images (like the [21st Century brand page](https://pillser.com/brands/21st-century)). That's a lot!
## AVIF
The realization that I had was that, just how I use [AVIF](https://caniuse.com/?search=AVIF) for product images themselves (because the file size is smaller), I can use AVIF to reduce the size of the LQIP. Here is what the same image looks like in AVIF:
```html
<div style="border: 1px solid #eee; width: 320px; aspect-ratio: 2469/1606; background-image: url(data:image/avif;base64,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);background-size:100% 100%"></div>
```
The above is now 1,019 bytes (or 50% of the original LQIP).
## Using sharp to convert PNG to AVIF
`thumbhash` defaults to producing png images. Perhaps, this is to support a broader range of browsers (AVIF has 93.62% browser support). However, I made a conscious decision that it is an acceptable trade-off to use AVIF for the placeholder images if it means that I can reduce the image size by 50%.
Therefore, I am using `thumbhash` to generate the LQIP, and then using `sharp` to convert the PNG to AVIF. Here is the underlying code:
```ts
import sharp from 'sharp';
import { rgbaToThumbHash, thumbHashToDataURL } from 'thumbhash';
const dataUrlToBuffer = (dataUrl: string) => {
const match = dataUrl.match(/^data:[^;]+;base64,([^"]+)/u);
if (!match) {
throw new Error('Invalid data URL');
}
const [, base64] = match;
return Buffer.from(base64, 'base64');
};
export const generateThumbHashDataUrl = async (image: Buffer) => {
const smallImage = await sharp(image).resize(100);
const { data, info } = await smallImage
.ensureAlpha()
.raw()
.toBuffer({ resolveWithObject: true });
const dataUrl = thumbHashToDataURL(
rgbaToThumbHash(info.width, info.height, data),
);
return `data:image/avif;base64,${(
await sharp(dataUrlToBuffer(dataUrl)).avif().toBuffer()
).toString('base64')}`;
};
```
The conversion happens when uploading the image to the database, therefore the overhead does not impact the user experience.
And that's it! Using this simple technique I was able to significantly reduce the page size when there are a lot of images. | lilouartz |

1,891,474 | The top tools for implementing ecommerce search in React | Written by Saleh Mubashar✏️ In the highly competitive field of ecommerce, every click matters. A... | 0 | 2024-06-20T13:24:09 | https://blog.logrocket.com/top-tools-implementing-ecommerce-search-react | react, webdev | **Written by [Saleh Mubashar](https://blog.logrocket.com/author/salehmubashar/)✏️**
In the highly competitive field of ecommerce, every click matters. A good search experience plays an important role in this. In this article, I will discuss four tools for implementing search functionalities in a React frontend. The tools include:
* Algolia
* Typesense
* Meilisearch
* Elasticsearch
We will explore key features that every search tool should have, such as auto-complete suggestions, typo tolerance, real-time results, and more. While these tools offer diverse ecommerce solutions beyond search, our focus will be on their search capabilities.
## Algolia
[Algolia](https://www.algolia.com/doc/) is one of the most popular hosted search engines, offering multiple solutions in the ecommerce field. It integrates seamlessly with major frameworks, libraries, and platforms like Shopify and WordPress.
Algolia provides API clients for various programming languages and platforms, along with pre-built UI components and libraries for direct integration.
### Algolia features
* **Instant search**: Algolia offers InstantSearch libraries for most frameworks and libraries, allowing users to search as they type, as well as the option to filter and sort results
* **Auto-complete**: Algolia provides an [open source JavaScript library](https://github.com/algolia/autocomplete) for building auto-complete search components. It also provides a recommendation library that works with its API client
* **Latest AI tools**: With Algolia, you gain access to [NeuralSearch](https://www.algolia.com/doc/guides/getting-started/neuralsearch/), which allows the engine to understand natural language and deliver relevant results
* **Typo tolerance**: Algolia's search engine can handle typos, as well as offering parameters to adjust the level of tolerance
* **Relevance tuning**: You can fine-tune the relevance of search results so that the most relevant items are displayed first
### Algolia pricing
A big drawback of third-party tools like Algolia is that the cost of searching and indexing can escalate as your application scales. However, Algolia offers a decent free tier, sufficient for getting started.
The free tier includes 10k search requests per month and up to a million records. However, certain advanced features, such as AI capabilities, are accessible only through premium plans. Additional requests cost $0.50 per 1k requests and $0.40 per additional 1k records per month.
### Algolia demo
Now, let’s create a simple search field using Algolia in React. For this, we can use [React InstantSearch](https://www.npmjs.com/package/react-instantsearch), an open source React library that uses Algolia’s search API to create search functionalities. The library contains pre-built widgets such as `InstantSearch`, `AutoComplete`, `GeoSearch` (to search for locations), and ecommerce-specific options like sorting and filtering.
The `InstantSearch` component is the root provider of all widgets and hooks. You need to pass it the `indexName`, which is your search UI’s main index, and the `searchClient`, which is an object containing your application ID and search API key. For this demo, I will use the keys and index provided in the official docs.
Within the `InstantSearch` component, you can add multiple different widgets. For this example, I am adding a simple `SearchBox` widget. Next, we can use the `Hits` component to display the results. The complete demo and code can be seen in this [CodeSandbox example](https://codesandbox.io/p/sandbox/weathered-leftpad-prl38t).
## Typesense
[Typesense](https://typesense.org/) presents itself as an open source and easy-to-use alternative to Algolia. It offers many similar search features, but Typesense lacks the extensive suite of tools beyond search functionalities that Algolia provides.
Typesense is a lightweight engine, resulting in better performance, but this means that it is only truly optimized for smaller datasets.
Typesense can either be self-hosted or run on the Typesense cloud. It provides client libraries for JavaScript, Python, PHP, and Ruby, while community-maintained client libraries are available for other languages and ecosystems. Like Algolia, Typesense supports all the major ecommerce platforms, CMSs, and frameworks.
### Typesense features
* Autocomplete and search-as-you-type, similar to those in Algolia
* Out-of-the-box typo tolerance and handling, as well as all the basic features like tuneable search rankings, filtering, and sorting and grouping data
* Integration of major LLMs to provide AI-assisted search features like similarity search, semantic search, visual search, recommendations, etc., using vector search
* Image and voice search. Typesense is the only one of the four tools mentioned in this article that supports image and voice search
* Offers a built-in conversational search feature that allows users to send questions and get responses, based on the data indexed in Typesense
* Emphasis on user privacy. No collection of usage analytics or personal data
### Typesense pricing
Typesense is a much more affordable option than Algolia, particularly for smaller-scale applications. It follows a fixed pricing model where users are charged per hour for using the dedicated cluster. The number of searches or queries is not priced:
* The self-hosted version is open source and so, completely free, excluding your infrastructure costs
* A cluster in the cloud-hosted version cost $0.03 per hour, with the first 720 hours free. The outgoing bandwidth costs $0.11 per GB, with the first 10 GBs free
### Typesense demo
Now, let’s create a simple search field using Typesense in React. For a search UI using Typesense, you can use the same InstantSearch library created by Algolia. The [Typesense Instantsearch Adapter](https://github.com/typesense/typesense-instantsearch-adapter) allows you to utilize the core Instantsearch.js library while using the TypeSense API.
Within the InstantSearch library, there are different wrappers for different frameworks. For React, you can use [react-instantsearch](https://github.com/algolia/react-instantsearch). You can install all the required packages in your React App using the following command:
```yarn
npm install --save typesense-instantsearch-adapter react-instantsearch-dom @babel/runtime
```
The basic widgets, steps, and layouts are exactly like the ones discussed in the Algolia demo. The main difference is in the search client setup. `TypesenseInstantSearchAdapter` is used to create an adaptor. Your API key and information about the node is specified in the configuration. This search client is then used for the `InstantSearch` component.
The complete code can be seen below. Keep in mind that you will need to sign up with TypeSense to get the API key, so I will only be providing the code and not the full demo:
```javascript
import React from "react";
import ReactDOM from "react-dom";
import { SearchBox } from "react-instantsearch-dom";
import TypesenseInstantSearchAdapter from "typesense-instantsearch-adapter";
const typesenseInstantsearchAdapter = new TypesenseInstantSearchAdapter({
server: {
apiKey: "your-api-key",
nodes: [
{
host: "hostname",
port: "port",
path: "", // Optional.
protocol: "http",
},
],
}
});
const searchClient = typesenseInstantsearchAdapter.searchClient;
const App = () => (
<InstantSearch indexName="products" searchClient={searchClient}>
<SearchBox />
<Hits />
</InstantSearch>
);
```
## Meilisearch
[Meilisearch](https://www.meilisearch.com/) is a relatively new search engine that aims to provide a fast search experience for smaller and simpler applications where performance is the priority. It provides both a self-hosted open source version and a cloud-hosted one.
The platform supports API wrappers and SDKs for all major languages, as well as support for platforms like Firebase and Gatsby. Integrations for popular frontend frameworks are also provided. Meilisearch accepts data in JSON, NDJSON, and CSV formats, allowing you to search through this data via a RESTful API.
Although Meilisearch lacks the variety of features found in larger tools like Algolia, it is excellent for simpler use cases such as a basic search bar or sorting table. Due to its smaller size, Meilisearch is also highly performant.
### Meilisearch features
* Built-in typo tolerance
* Search-as-you-type and fast response times
* Support for multiple languages, including Chinese, Japanese, Hebrew, and languages using the Latin alphabet
* Customizable search. You can adjust the relevance of search rankings, apply filters, and highlight certain words
* It provides a Geo Search feature that allows users to sort results based on geographical location
* Cloud-hosted plans provide search analytics, website crawling, and an interface to manage your data
### Meilisearch pricing
Like Typesense, Meilisearch is a decently affordable option. Besides its open source version, users have three tiers to choose from in the cloud-hosted version. Keep in mind that most search features are consistent across both versions. However, additional features like analytics and a data management interface are limited to the cloud-hosted version.
The open source version is completely free, but, you will have to self-host it. The cloud-hosted version includes the following plans:
* **Build plan**: Starts at $30 per month with a 14-day free trial. Includes 100k searches and 1m documents
* **Grow plan**: Starts at $300 per month. Includes 1m searches and 10m documents
* **Enterprise**: Custom quote
### Meilisearch demo
Now, let’s create a simple search field using Meilisearch in React. Once again, we will use the InstantSearch library by Algolia to create our search field. You can get started by installing `react-instantsearch` alongside the Meilisearch client using the following command:
```yarn
npm install react-instantsearch @meilisearch/instant-meilisearch
```
Next up, you need to [create your master key](https://www.meilisearch.com/docs/learn/security/basic_security#creating-the-master-key-in-a-self-hosted-instance) and then use it alongside the hostname to create the `searchClient` object. This will allow you to connect to the Meilisearch client. The search bar itself will be created exactly how we did in the previous examples. The code will look somewhat like this:
```javascript
import React from 'react';
import { InstantSearch, SearchBox, Hits, Highlight } from 'react-instantsearch';
import { instantMeiliSearch } from '@meilisearch/instant-meilisearch';
const { searchClient } = instantMeiliSearch(
'host',
'masterkey'
);
const App = () => (
<InstantSearch indexName="products" searchClient={searchClient}>
<SearchBox />
<Hits />
</InstantSearch>
);
export default App
```
You can see the official [React example in this CodeSandbox](https://codesandbox.io/p/sandbox/ms-react-is-f98w2w).
## Elasticsearch
[Elasticsearch](https://www.elastic.co/elasticsearch) is a RESTful search and analytics engine focused on searching through large amounts of data and performing text analysis. Unlike the other tools discussed in this article, Elasticsearch is not primarily focused on frontend development; instead, it is a general search engine designed for handling large datasets.
Elasticsearch offers a wide range of integrations, plugins, and tooling support. Although it is not the easiest to set up, it can be a great option for larger teams. It provides search clients for all major languages and frameworks. However, tools like Algolia, Meilisearch, and Typesense offer better support for ecommerce platforms and CMSs like WordPress, as well as better frontend integrations.
### Elasticsearch features
* Ecommerce focused search features such as relevancy and personalized suggestions, along with user insights
* Support for LLM (Large Language Models) with the Elasticsearch Relevance Engine to integrate AI into search applications
* Typo-tolerance is supported, although not as performant as the other tools discussed
* Geospatial search and the ability to search across multiple datasets
* Search features like relevance scoring, sorting, and filtering
* Excellent security features, including password protection, role-based access control, and IP filtering
### Elasticsearch pricing
Elasticsearch is one the more pricier options for search functionality tools. As a result, it is often suited for larger applications and companies that have large datasets. Although it has a free [self-hosted version](https://www.elastic.co/guide/en/elasticsearch/reference/current/run-elasticsearch-locally.html), there will be significant infrastructure costs.
For the cloud-hosted version, there are four tiers:
* **Standard**: $95 per month containing all the core Elastic Stack features, including security
* **Gold**: $109 per month. Additional features like reporting and multi-stack monitoring
* **Platinum**: $125 per month. Advanced Elastic Stack security features and machine learning
* **Enterprise**: $175 per month
### Elasticsearch demo
You can create a search application in React using [Elastic Search UI](https://docs.elastic.co/search-ui), a JavaScript library, with Elastic’s `react-search-ui`. You can see a [cool demo here](https://32xp9i.csb.app/search-bar-in-header/search?q=hi&size=n_20_n).
Another common approach is to use the UI components provided by Reactive Search, which is an open source UI components library for React and React Native that works with Elasticsearch backends. You can see a [demo here](https://blog.reactivesearch.io/react-search-ui-tutorial#heading-step-2-setup-with-searchbox-and-all-the-filter-components-from-reactivesearch).

1,894,830 | Unboxing Pieces App for Developers: Your Workflow Copilot 🚀🔥 | As a backend software engineer, developer advocate, and technical writer who has worked with brands... | 0 | 2024-06-20T13:23:50 | https://dev.to/kwamedev/unboxing-pieces-app-for-developers-your-workflow-copilot-1i6p | productivity, githubcopilot, developers, workflow | As a backend software engineer, developer advocate, and technical writer who has worked with brands that span the fields of insurance, data management, software testing, and healthcare (cancer research) like DbVisualizer, the highly rated database client and SQL editor in the world, LambdaTest Inc., Insurerity Digital, and Yemaachi Biotech Company, there’s no better person to describe how a day in the life of an engineer feels like.
In my typical day as an engineer and dev advocate, I’m mostly found writing JavaScript and SQL, and developing on macOS while using a handful of tools that are indispensable in my day-to-day work such as **VSCode** IDE, **Google Chrome browser**, **GitHub Desktop**, **Slack Desktop**, **Notion**, **Notion Calendar**, **Postman**, **Anaconda**, **Android Studio**, etc.
Before being introduced to the Pieces app for developers I was a heavy user of Google Drive. I would often use Google Drive to save my code snippets, events, and other workstream materials. Other times when I'm working on a project and I have to save some code snippets, infrastructure platform login credentials, keys, links, and other stuff (db urls, errors) somewhere, I’d use the notes app on macOS or notion. One other important part of my work that I had to always save somewhere so I don’t lose track of is tickets that have been assigned to me or reports from a QA engineer.
This method of saving tiny pieces of important information lacked cohesion and remembering the exact location of data was sometimes a pain in the arse until I chanced on [Pieces for Developers](https://pieces.app/).
When I first heard about the Pieces for Developers, I was intrigued by its promise to streamline and enhance productivity for coding and project management. As a developer, I am always on the lookout for tools that can help optimize my workflow, and Pieces seemed to offer a unique blend of features designed specifically for our needs.
My initial interest in [Pieces](https://pieces.app/) stemmed from its focus on helping developers organize and manage code snippets, notes, and other resources intuitively. The idea of having a central repository where I could quickly store and retrieve useful code snippets, docs, and other related information to my projects was appealing. This feature promised to save me from the chaos of scattered notes and endless searching through old projects to find reusable code.
Upon setting up Pieces, I was eager to achieve several productivity benefits including but not limited to collaboration and improved organization.
**Collaboration Purposes**
As I often work in a team environment, I was looking for ways to improve collaboration. Pieces’ ability to share resources and insights with team members promised to foster better communication and collective knowledge sharing.
**Code Reusability**
I wanted to efficiently store and categorize my frequently used code snippets, making reusing them across different use cases or projects easier. This would reduce redundant coding efforts and improve the consistency and quality of my work.
**Improved Organization**
Through the consolidation of my notes, documentation, and code snippets in one place, I aimed to create a more organized and accessible knowledge base. This organization would allow me to quickly find the information I needed without sifting through disorganized files or online searches.
**Seamless Platform Integrations**
Pieces’ potential to integrate with other development tools and platforms I use, such as VSCode, Slack, GitHub, MS Teams, Google Chrome browser, etc, was a significant draw. I hoped this integration would facilitate a smoother workflow and reduce the time spent switching between different applications or tools.
## Why Review a Product like Pieces for Developers?
With my experience working across spanning industries that include insurance, data management, software testing, and healthcare, I understand the challenges developers face daily. This has given me knowledge of the tools and practices that can significantly enhance a developer's productivity and workflow.
Given this background, I saw a formal review of Pieces as an excellent opportunity to provide invaluable insights to my followers and readers. The name is Pieces for ‘Developers’ - This tells us that the ulterior goal of Pieces is to make the lives of developers easier.
Below are the reasons I believe it would be beneficial to review Pieces and share my findings with my audience:
**Collaboration Purposes**
Many of my readers work in team environments where collaboration and knowledge sharing are indispensable, therefore Pieces’ ability to facilitate resource sharing and improve team communication can be a game-changer. Through this review, I can highlight its collaborative features and demonstrate how it can boost team productivity.
**Addressing Common Dev Challenges**
Developers often face challenges like managing code snippets, organizing documentation, and maintaining efficient workflows. Pieces promises to address these issues by providing a centralized repo for code snippets, notes, and other resources.
My audience, comprising developers who likely encounter similar challenges, could greatly benefit from understanding how Pieces can help ease their way out.
## Setting Up the Pieces App
Navigate to the [pieces app documentation](https://docs.pieces.app/installation-getting-started/what-am-i-installing). Select your installer based on the operating system of your computer. Run the installer and you’re good to go. In the navigation menu of the documentation, you will find a list of Pieces App plugins and extensions for VSCode, JetBrains, web, MS Teams, Azure Data Studio, Obsidian, and Jupyter.
After installing Pieces, the first step in the onboarding process is to set up a personalized pieces experience by specifying your
- Developer Persona and Languages
- Typical Toolchain
- Experience Level
- Project Types (individual, team, both)
Next, Pieces will help you choose how to effortlessly search, refer, and be able to reuse all your saved materials.
After setting up preferences, you can also do your cloud integrations so everything syncs. You can choose to use GitHub, Google, etc.
## Pieces for Developers: the Good & the Bad
In this first-impression blog, we’ll get into the good, and the bad and what it means for a Developer Advocate like myself and the productivity of my work-in-progress journeys. Time to get started!
## The Bad - The Ugly 🙂
Below are a few scenarios and features where Pieces fell short:
**Performance on Intel Architecture MacBooks**
Intel MacBooks experience a noticeable lag when trying to exit the screen where Pieces is open. This high resource consumption results in performance barriers on older Intel architecture.
**Limited Collaboration Features 🫥**
The collaboration features are somewhat limited. When attempting to share snippets with a team, I found it difficult to manage permissions and there was no support for real-time collaboration on snippets although the features/ fuctions were visible.
Additionally, providing detailed access controls (super admin, admin, etc) to manage who can
- view,
- comment,
- edit, and
- delete a snippet would enhance team collaboration on Pieces.
## The Good - The Awesome! 💪
This section will highlight the outstanding features of Pieces:
**Live Context 💡**
The Live Context feature in Pieces provides context-aware and real-time insights into your code. Because of its ability to comprehend and adjust to your work process, Pieces Copilot can offer apt support based on your work style, where you work, and when, giving you the freedom to recall anything and communicate with everything.
To enabling Live Context in Pieces, do this:
- Navigate to the Machine Learning section of the [Pieces Desktop App settings](https://docs.pieces.app/installation-getting-started/what-am-i-installing) and activate the Workstream Pattern Engine.
- Follow the prompts to adjust the necessary permissions if required.
- Navigate to the Copilot Chats, begin your work, then initiate a conversation with the Pieces Copilot, utilizing Live Context for enhanced assistance.
**How Live Context Works**
**Resolution of Errors**
You can expedite project hand-offs and resolution of errors with Live Context. The copilot can provide accurate recommendations without requiring you to explicitly input the context of your error by gathering relevant workflow data.
Let’s look at this warning I’m encountering in my backend project in VsCode at the moment.
Since Pieces has relevant data of my workflow, I can ask Pieces Copilot+ to help me resolve it - “How would you take care of the warning in my VSCode Terminal?”. It will then utilize its relevant context or workflow ability to resolve the error as shown below:
Here, Pieces tells us how to get rid of the MongoDB Driver warning.
**Present Time Workflow Assistance**
You can manage your tasks across several tools and sessions with the aid of Live Context. Whether you're hopping from browser-based research, google chats or coding in your text editor, Pieces Copilot+ keeps track of your actions and offers helpful, context-aware support quickly.
For example, before I wrote about this ‘Live Context’ feature, I was doing some research around it. When I asked Pieces what I had been doing for the past hour, it provided me with the exact flow.
**Improving Interaction with Developers**
To assist you in more efficiently managing discussions and teamwork, Pieces Copilot+'s Workstream Pattern Engine collects and analyzes interaction data. Making summaries and action items based on your conversations and actions falls under this category.
For example, I can ask it to generate points for our sync meeting tonight at Pieces.
The Workstream Pattern Engine collects and analyzes data from various interactions throughout the day, including code reviews, comments, and direct communications within the team (slack, MS Teams, etc). It then uses the collected data to generate a concise response for the sync meeting.
- The domain facilitates easy sharing and collaboration with team members or other developers. You can share specific snippets or resources by providing a link to your cloud domain.
- Your personalized cloud domain in Pieces acts as a backup hub for your snippets, notes, and other resources. While it allows you to store and restore your materials, all snippets are saved on-device by default and only uploaded to the cloud when you manually perform a backup. Live sync functionality is not available, meaning that updates made on one device won't automatically sync to others.
- Your cloud domain acts as a backup for your data. In case of hardware failure or data loss on your local device, you can easily recover your snippets and resources from your cloud domain.
Etc
**Sharing Saved Snippets or Materials**
With Pieces, you can share your saved materials publicly by generating a shareable link and putting it out there by following the illustration shown below:
After generating the shareable link, feel free to share this link with your team. They can save it to their pieces and edit it if need be!
Another interesting thing is that you can also add project-related people to your saved material.
Related people are more for Pieces to recommend people who have worked on similar things as you save snippets from various places. If a user shares a saved material to another user, they can save it to their personal saved materials on Pieces and edit it (if need be), but the original user will only have the version that they created and had shared originally.
To add related people, do this:
- Click on the menu icon shown in the image below
- Add the name and email of the related person and click on ‘Create’ to create.
**Auto-enrichment 🧑💻**
Immediately you save a snippet, Pieces App automatically enriches it with related **links**, **tags**, **descriptions**, and other **metadata**. This is driven by AI and machine learning algorithms that analyze your snippets and the context in which they are used. You can edit these descriptions, tags, related links, etc if you wish to. For example, embedding a different link (video, article) in your related links.
Note that this feature is on-device - meaning that all the processing and enrichment of the code snippets happen locally on the user's device, rather than on external servers.
Since all processing happens locally, sensitive code and data never leave the user's device. This ensures that proprietary or confidential information remains secure. Also, users do not need to worry about their code being stored or processed on third-party servers, reducing the risk of data breaches.
**What does the Auto-Enrichment Feature Come with?**
- **Improved Searchability**: With tags, descriptions, and related links automatically added, finding the right snippet becomes much easier. You can search using full-text search, blended, natural language, or snippets.
- **Enhanced Context**: Having related links and contextual information at your fingertips helps you understand and utilize snippets more effectively. It reduces the need to search for additional resources manually.
- **Time-Saving**: Automatic enrichment saves time by eliminating the need to annotate and organize snippets manually. This allows you to focus more on coding.
- **Better Collaboration**: When sharing snippets with team members, the added metadata provides them with all the necessary context to understand and use the snippets effectively.
**Generating GitHub Gist 🚀**
This function allows developers to quickly and seamlessly share code snippets on GitHub. To create a GitHub Gist, follow the steps below:
- Open a snippet on the Pieces App. Click on the menu icon on the right-hand side of the window.
In the pop-up window, click on the shareable link’s ‘manage’ button shown in the image below:
Next, click on the ‘Generate Github Gist’ button.
Edit the contextual metadata and the description (if you wish to) and click on ‘Create’ to create the gist. Note that you will have to connect your GitHub account before this action can be done.
**GitHub Gist Use Case**
Grace, a software developer, is working on a new feature for a web application. She encounters a complex bug in her JavaScript code that she is unable to resolve on her own. Grace decides to seek help from her colleague, Dillon, who has more experience with JavaScript.
**Process Flow**
-> Grace identifies the specific code snippet that is causing the issue. She saves the problematic code snippet in the Pieces App. The app automatically enriches the snippet with relevant metadata, such as a description of the issue, tags, and any related links.
-> Using the Pieces App, she uses the 'Generate GitHub Gist' function to create a GitHub Gist from the saved snippet. This function automates the process of creating a Gist by integrating with Grace's GitHub account. The app generates a link to the GitHub Gist, which Alice can easily share. Alice sends this link to Dillon.
-> He receives the Gist link and opens it in his browser. He reviews the code and uses GitHub's commenting feature to provide feedback and suggest changes. Grace reviews the comments and updates. She then incorporates the suggested changes into her local codebase, resolving the bug.
**Saving Snippets 🔥🔥**
**Use Cases**
The code below is a backend code I wrote for an open-source app. What I have here is a code that connects my application to MongoDB. I want this snippet to be saved so that next time I’m writing some backend, this code snippet will be available to me any moment.
To do this, follow the steps below:
- Open VSCode, and install the Pieces for VSCode extension.
- Highlight the code, right-click, and select ‘Pieces’ from the menu.
- From the pop-up menu, select ‘Save to Pieces’ to save the snippet.
- Now, go ahead and open Pieces and you should see the snippet saved.
**Dragging and Dropping an Image**
With Pieces, you can drag and drop an image, which will be automatically saved! One crazy thing is that you could also view the image as code rather than an image. Dragging and dropping an image into Pieces to turn it into actual text (code snippets) leverages optical character recognition (OCR) technology.
This is a simple demo video to illustrate the drag-and-drop method in Pieces. In this video, you’re also going to learn how to view the image (screenshot of a code snippet) as code.
{% youtube kiSS8SUtq00 %}
Are you watching a tutorial and want to use a code in the tutorial? Take a screenshot, drag and drop the image into Pieces, and view it as code! Pieces is simply developer-first!
There’s also **Context Preview** - a feature in the Pieces App that provides users with relevant information about their saved code snippets and other developer materials at a glance. This feature is designed to enhance productivity by walking developers through the context of their snippets.
**Saving using the Chrome extension**
In this section of the blog, we’re going to experiment with this blog on [Unit testing with mocha and chai](https://dev.to/kwamedev/unit-testing-with-mocha-chai-4gdh).
Let’s assume we are interested in this code. To copy it for our use, we just have to hover over the code and Pieces’ functions will pop up as shown in the image above. (provided the [Chrome extension](https://chromewebstore.google.com/detail/pieces-for-developers-cop/igbgibhbfonhmjlechmeefimncpekepm) has been installed). Click on ‘Copy And Save’.
Great! Now we can see that our code snippet in our browser has been saved on Pieces! 💪
If you want to share this code sample with your teammates, just click ‘Share’. This will save the code, and generate a link to the code sample which will then be automatically saved to your clipboard.
There’s also the ‘Ask Copilot’ function. This function provides real-time assistance and insights about code samples directly within the browser. Particularly, it is useful for developers looking for quick explanations, suggestions, or solutions related to specific code snippets.
A dialog box or sidebar will appear after clicking it, prompting you to enter your question about the selected code snippet. For example, you might ask for an explanation of the code, potential optimizations, or how to fix a bug.
Crazy right?! 😀. Remember this feature works the same for Pieces’ VS Code Extension. **Highlight a code -> right click -> ask Copilot**!
**Exploring Curated Collections from the Pieces Team**
The team members at Pieces have come together to curate a collection full of some of the most useful code samples ranging from JS to TS to Node, Dart and Python (snippets for other languages and frameworks are coming soon). Add these snippets to your Pieces for some extreme time-savers.
To explore these collections, click on ‘Add Materials’ and in the pop-up window, click on ‘Explore Curated Collections’. Bingo! 🚀
**Code Analysis 🧑💻**
Copilot Chats in Pieces offers numerous advantages for developers preparing for technical assessment interviews such as Data Structures and Algorithms (DSA) interviews, etc. Let’s look at how to leverage Pieces in code analysis and in the preparation for such assessments.
- Launch the Pieces app and click on the ‘Go To’ icon at the top right.
- In the drop-down menu, select ‘Copilot Chats’
- In the input field, you can choose to drag and drop a screenshot, paste a code or ask a technical question as shown below.
**Use Case**
Billy, a software developer, is preparing for a technical interview and practicing a Leetcode DSA problem on binary search trees (BST). Billy has chanced on a solution written in JavaScript on Leetcode.
- He takes a screenshot of the code snippet (solution), opens up Copilot Chats on Pieces and drops the image.
- Pieces then extracts the code from his image.
- Billy then continues to ask technical questions: explanation, potential improvements, etc about the code in question as shown below. You could also ask Copilot to convert a code snippet to a different language. Say from JavaScript to Python, etc
Asking further questions:
This is crazy, isn’t it?! 😀
## Wrapping Up! 🫡
**OverAll Impression of Pieces**
My overall impression of the Pieces App is up the roof! Well-designed with a clear focus on improving productivity and organization for developers, it has a wide range of features, such as snippet management, integration with popular platforms, and context-aware functionalities, making it a powerful addition to any developer's toolkit. What excites me most is the automatic generation of tags, descriptions, and related links adds significant value by simplifying the process of managing and retrieving code snippets.
**Potential for the Pieces as it Evolves**
The potential for the Pieces App is substantial. As Pieces continues to progress , it will surely become an indispensable tool for developers by refining its existing features and extending its flair. Enhancing performance, especially on older hardware, and improving collaboration features can make it more appealing to larger development teams and enterprises. Additionally, incorporating more advanced AI-driven functionalities for code suggestion and error detection can further elevate its utility in the development space.
**Continued Use in Engineering & Developer Advocacy Career**
I see myself continuing to use the Pieces App throughout my engineering and developer advocacy career. Its ability to smoothen the management of code snippets and integrate with tools I already use makes it a valuable asset to me and my team.
As developers, there’s always so much context to deal with. From handling large code bases to useful snippets (that we sometimes forget to save), to screenshots, etc, Pieces has made it its goal to bring all these together!
The ongoing improvements and the team’s responsiveness to feedback also provide confidence that the product will only get better with time.
**Number One Feature/Benefit Wished For**
The number one feature I wish Pieces App had is real-time collaboration capabilities. Being able to work on code snippets simultaneously with other team members, along with detailed access controls, would significantly enhance the app’s utility in a team setting.

1,894,820 | Securing Kubernetes Clusters with Network Policies | Kubernetes, a container orchestration platform, has become a cornerstone of modern application... | 0 | 2024-06-20T13:16:33 | https://dev.to/platform_engineers/securing-kubernetes-clusters-with-network-policies-41fm | Kubernetes, a container orchestration platform, has become a cornerstone of modern application deployment. As the adoption of Kubernetes continues to grow, ensuring the security of these clusters has become a critical concern. One effective way to enhance security is by implementing network policies, which provide granular control over network traffic within and between pods.
### Understanding Network Policies
Network policies are a Kubernetes resource that defines a set of rules governing network traffic. These policies are applied at the pod level, allowing for fine-grained control over incoming and outgoing traffic. By default, Kubernetes allows all traffic between pods, which can lead to security vulnerabilities. Network policies address this by enabling administrators to specify which pods can communicate with each other and under what conditions.
### Creating a Network Policy
To create a network policy, you need to define a YAML file that specifies the policy rules. Here is an example of a basic network policy:
```yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: allow-http
spec:
podSelector:
matchLabels:
role: web-server
ingress:
- from:
- podSelector:
matchLabels:
role: client
- ports:
- 80
```
This policy allows incoming HTTP traffic (port 80) from pods labeled as `role: client` to pods labeled as `role: web-server`.
### Applying Network Policies
Once the YAML file is created, you can apply it to your Kubernetes cluster using the `kubectl` command:
```bash
kubectl apply -f network-policy.yaml
```
### Types of Network Policies
There are two primary types of network policies:
1. **Ingress Policies**: These policies control incoming traffic to a pod.
2. **Egress Policies**: These policies control outgoing traffic from a pod.
### Example: Restricting Outgoing Traffic
To restrict outgoing traffic from a pod, you can create an egress policy. Here is an example:
```yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: restrict-egress
spec:
podSelector:
matchLabels:
role: database
egress:
- to:
- podSelector:
matchLabels:
role: logging
- ports:
- 5432
```
This policy restricts outgoing traffic from pods labeled as `role: database` to only allow connections to pods labeled as `role: logging` on port 5432.
### Example: Isolating Pods
To isolate pods from each other, you can create a network policy that denies all traffic between them. Here is an example:
```yaml
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: isolate-pods
spec:
podSelector:
matchLabels:
role: isolated
ingress:
- from:
- podSelector:
matchLabels:
role: isolated
egress:
- to:
- podSelector:
matchLabels:
role: isolated
```
This policy denies all traffic between pods labeled as `role: isolated`, effectively isolating them from each other.
### Best Practices for Network Policies
When implementing network policies, it is essential to follow best practices to ensure effective security:
1. **Use Labels**: Use labels to select pods and apply policies, making it easier to manage and update policies.
2. **Keep Policies Simple**: Avoid complex policies with multiple rules, as they can be difficult to maintain and debug.
3. **Test Policies**: Thoroughly test policies before applying them to production clusters.
4. **Monitor Policy Enforcement**: Regularly monitor policy enforcement to ensure they are working as intended.
### Conclusion
Network policies are a powerful tool for securing Kubernetes clusters. By understanding how to create and apply network policies, you can effectively control network traffic within and between pods, enhancing the [overall security](https://platformengineers.io/blog/securing-kubernetes-beyond-rbac-and-pod-security-policies-psp/) of your cluster. As a critical component of [platform engineering](www.platformengineers.io), network policies play a vital role in ensuring the integrity of your Kubernetes environment. | shahangita | |

1,894,816 | Improve React Navigation with xState v5 | TL;DR If you just want to see the code, it is here. And this is the PR with the latest... | 27,790 | 2024-06-20T13:14:09 | https://dev.to/gtodorov/improve-react-navigation-with-xstate-v5-2l15 | reactnative, xstate, mobile, typescript | ### TL;DR
If you just want to see the code, it is [here](https://github.com/g-todorov/ReactNativeXStateExample). And [this](https://github.com/g-todorov/ReactNativeXStateExample/pull/1/files) is the PR with the latest changes that are discussed in the post.
### Introduction
This is a short follow up post that focuses on fine tuning the navigation integration. For full context refer to the previous [part](https://dev.to/gtodorov/react-native-with-xstate-v5-4ekn). The change was inspired by a discussion in the [Stately discord channel](https://discord.com/invite/xstate), which I recommend joining.
### Improvement
As I previously stated, I use xState as the backbone of the application. The end goal is to leave all the business logic and state orchestration to the machines and use the views/screens (in this case React Native ones) for the sole purpose of displaying the correct data in a fancy way. This not only makes the application framework agnostic, but also prepares it for proper model based testing.
That's why I had concerns with how the routing logic was tightly coupled with React via the `useNavigator` hook. When I started using React Navigation, I thought that utilising the `navigation` object through props is the only way to operate with the methods that it offers and a hook seemed as the obvious choice to synchronise machines and navigation. Slowly, the application evolved to rely solely on `navigationRef`, which left space for improvement.
Now we can move the navigation listener from the `useNavigator` hook into a `fromCallback` actor. Invoking the actor at the root level of the machine that is in charge of the navigation provides the same functionality without the need to go through the react-specific hooks.
```typescript
actors: {
homeMachine,
listMachine,
navigationSubscriber: fromCallback(({ sendBack }) => {
const unsubscribe = navigationRef.addListener("state", (_event) => {
const screenRoute = getCurrentRouteName();
if (screenRoute) {
sendBack({ type: "NAVIGATE", screen: screenRoute });
}
});
return unsubscribe;
}),
},
```
As an extra step we can abstract the actor and reuse it for other machines in charge of navigation. In my case I export it from `machines/shared/actors.ts`
The last thing that's worth mentioning from this PR is a small change in the naming convention. Each machine that is tied with a `<Stack.Navigator>` and supports the `NAVIGATE` event will be renamed to `machineName.navigator.ts`. Since all machines share the same folder, and only few of them are serving this special role, I think we can give them a visual distinguisher in the folder tree.
### Conclusion
Since we have the base set up, the upcoming posts will focus on `Registration Wizard` and `Notification System`. | gtodorov |

## ¡Ignora archivos solo para ti en Git: domina .git/info/exclude como un pro!
Ey Devs!, ¿alguna vez han querido excluir archivos de Git solo para su repositorio local sin afectar a sus colaboradores? ¡Entonces .git/info/exclude es su nuevo mejor amigo!
**¿Qué es .git/info/exclude?**
A diferencia del archivo .gitignore, que se comparte con los colaboradores y se aplica a todos los clones del repositorio, .git/info/exclude es un archivo **personal** que reside en `.git/info/` y solo se aplica a **tu clon local**. Esto lo convierte en el lugar ideal para omitir archivos que solo son relevantes para tu configuración de desarrollo o que no deseas compartir con el mundo.
**¿Cuándo usar .git/info/exclude?**
Imagina estos escenarios:
* **Configuraciones de inicio de sesión personalizadas:** Si tu proyecto utiliza archivos de inicio de sesión confidenciales, como `.env` o `.credentials`, añádelos a `.git/info/exclude` para evitar que se confirmen accidentalmente.
* **Herramientas de desarrollo específicas:** ¿Utilizas herramientas que generan archivos temporales en el directorio de trabajo del repositorio? Añádelos a `.git/info/exclude` para mantener tu espacio de trabajo limpio y sin archivos innecesarios.
* **Archivos de prueba o borradores:** Si tienes archivos de prueba o borradores que no deseas que se incluyan en el historial de Git, `.git/info/exclude` es tu solución.
**¿Cómo usar .git/info/exclude?**
1. **Abre .git/info/exclude:** Puedes usar tu editor de texto favorito para abrir este archivo ubicado en la raíz de tu repositorio Git.
```bash
code .git/info/exclude:
```
2. **Agrega patrones de exclusión:** Cada línea en `.git/info/exclude` representa un patrón de archivo que deseas omitir. Git utiliza la sintaxis de exclusión de Git estándar, como comodines y expresiones regulares.
3. **Guarda:** Guarda los cambios en `.git/info/exclude`. ¡Listo! Los archivos que coincidan con tus patrones de exclusión ahora serán ignorados por Git en tu clon local.
**Ejemplo:**
Para omitir el archivo `test.txt` de tu repositorio local, agrega la siguiente línea a `.git/info/exclude`:
```
test.txt
```
**Recursos adicionales:**
* **Documentación oficial de Git sobre .git/info/exclude:** [https://git-scm.com/docs/gitignore/](https://git-scm.com/docs/gitignore/)
* **Artículo sobre "Ignorar archivos en Git sin agregarlos a .gitignore":** [https://stackoverflow.com/questions/653454/how-do-you-make-git-ignore-files-without-using-gitignore](https://stackoverflow.com/questions/653454/how-do-you-make-git-ignore-files-without-using-gitignore)
**¡Consejo profesional:**
* Utiliza comentarios en `.git/info/exclude` para describir los archivos o patrones que estás excluyendo para mejorar la legibilidad y el mantenimiento.
¡Con .git/info/exclude en tu arsenal, puedes mantener tu repositorio local limpio y organizado, sin sacrificar la flexibilidad de excluir archivos específicos para tu configuración de desarrollo!

The app will allow users to select a URL and generate a corresponding QR code. We will utilize ToolJet's visual app-builder to rapidly build a user interface and then connect to a Python module to generate QR codes from URLs.
Here's the preview of the application:
---
## Prerequisites
- **ToolJet**(https://github.com/ToolJet/ToolJet) : An open-source, low-code business application builder. [Sign up](https://www.tooljet.com/signup) for a free ToolJet cloud account or [run ToolJet on your local machine](https://docs.tooljet.com/docs/setup/try-tooljet/) using Docker.
- Basic knowledge of **Python**.
Begin by creating an application named _QR Code Generator_.
---
## Step 1: Design the User Interface
#### - Add a Container for the Header
1. Drag and drop a `Container` component onto the canvas.
2. Name it `headerContainer`.
3. Set its background color to `#0a60c6ff`.
#### - Add a Text Component for the App Name
1. Inside the `headerContainer`, add a `Text` component.
2. Set the text to "QR Code Generator."
3. Style it with:
- Text Color: `#ffffffff`
- Text Size: `24`
- Font Weight: `bold`
- Border Radius: `6`
#### - Add an Icon for the App Logo
1. Inside the `headerContainer`, add an `Icon` component.
2. Set the icon to `IconQrcode` and color to `#ffffffff`.
#### - Add a Table with URLs and Other Information
1. Drag and drop a `Table` component onto the canvas.
2. Name it `linksTable`.
3. Below is the database table structure that we are using for this application:
- `id`: Auto-generated
- `title`: String
- `url`: String
- `description`: String
4. Populate the `Table` component with data, based on the provided structure.
#### - Add a Text Component for the Table Header
1. Above the table, add a `Text` component.
2. Set the text to "URL Information."
3. Style it with:
- Text Color: `#0a60c6ff`
- Text Size: `24`
- Font Weight: `bold`
#### - Add a Modal for QR Code Generation
1. Drag and drop a `Modal` component onto the canvas.
2. Name it `generateButton`.
3. Set the Trigger button label to "Generate QR" and the Background color to `#0a60c6ff`.
#### - Add an Image Component to Display the QR Code
1. Inside the modal, add an `Image` component.
2. Name it `qrOutput`.
3. Use the below code for the Image component's URL property:
```python
data:image/png;base64,{{queries.QRGenerator.data}}
```
4. Similarly, use the below code for the Loading state property of the Image component:
```python
{{queries.QRGenerator.isLoading}}
```
_The above configuration will display the generated QR code in the Image component after we craft and run the related query(named `QRGenerator`)._
---
## Step 2: Implement Functionality
#### - Add a Python Script for QR Code Generation
1. Add a query named `QRGenerator` using the Run Python code data source.
2. Use the following Python code to generate the QR code:
```python
import micropip
await micropip.install("qrcode")
import qrcode
from io import BytesIO
import base64
def QR_Generator():
qr = qrcode.QRCode(
version=1,
error_correction=qrcode.constants.ERROR_CORRECT_L,
box_size=10,
border=4,
)
qr.add_data(components.linksTable.selectedRow.url)
qr.make(fit=True)
img = qr.make_image(fill_color="black", back_color="white")
buffered = BytesIO()
img.save(buffered, "PNG") # Specify the format as a string
img_str = base64.b64encode(buffered.getvalue()).decode('utf-8')
return img_str
QR_Generator()
```
_This code uses the `qrcode` library to generate a QR code from a selected URL in a ToolJet table component. The generated QR code is converted to a base64-encoded PNG image and returned as a string._
#### - Link the QR Generator to the Generate Button
1. Select the `generateButton` modal and add a new event handler to it.
2. Set up an `On open` event to run the `QRGenerator` query.
3. After the above configuration, the output of the `QRGenerator` query will be displayed in the `qrOutput` Image component based on the earlier configuration.
---
## Step 3: Test the Application
Select a row on the `Table` component and click on the `generateButton` modal to generate and view the QR code.
_You can save the QR code by right-clicking on the image and selecting `Save image as`. Alternatively, you can set up a Button component to download the image directly._
---
## Congratulations
Congratulations! You've successfully built a production-ready QR code generator. This application demonstrates ToolJet's capability to rapidly design clean user interfaces and extend functionality with custom code. While we used Python code in this tutorial, ToolJet also supports JavaScript code and Custom Components for users who want to extend the platform's functionality for very specific use-cases.

1,894,804 | Beyond Coding: Learn to interact with AI | What is the latest buzzword in the market? If you guessed AI, ChatGPT or prompt engineering then you... | 0 | 2024-06-20T12:49:51 | https://dev.to/rishika_kalita_80ef41e273/beyond-coding-learn-to-interact-with-ai-23l7 | ai, chatgpt, promptengineering, developer | What is the latest buzzword in the market? If you guessed AI, ChatGPT or prompt engineering then you are on the right track. I am sure everyone of us has recently seen a few (maybe more than a few!) articles with the title “20 prompts that you need for …”
But do we really need someone else to write these prompts for us? Being developers should we not be curious enough to explore this new area and write our own prompts?
These were some of the questions that came to my mind when I saw such posts and so I decided to dive deep into this new and exciting world of prompt engineering and explore it myself.
Before we begin this discussion, let me ask you a very simple question, what are prompts? In simple terms, a prompt is the act of verbalizing or expressing a desire to communicate something. This is precisely what we aim to achieve when writing prompts, i.e. to ask (inquire) about any subject matter we wish to explore. Subsequently, the next step is to understand how to enhance our prompting approach so that we can get meaningful and crisp responses.
## What you need to know?
Below are some of the key concepts that one should know to write good prompts.
####Keep it simple
Start by writing simple prompts and study the responses. Tweak a few words in the prompt and analyse how the response changes. Understand what works and what does not. Iterate over the prompts and refine.
####Use conversational tone
Communicate with the AI in a conversational tone where one participant is asking questions and the other, being highly knowledgeable, is answering the questions. Keeping this tone makes the whole interaction more human and makes it easier to understand.
####Understand the basic concepts
Follow some of the best practices of prompt writing like context setting, providing clear instructions, adjusting prompt length. It is also helpful when we provide background information relevant to the task as it reduces ambiguity.
####Try different approaches
Experiment with different prompt structures, like using instructions, examples, conditionals, etc. and see what gives the best results.
If the task is complex then break it down into multiple sub-tasks and use structured prompts with steps.
####Refining Prompt Iteration
Iteratively refining prompts as per your requirements is one of the most important steps that needs to be followed. It enhances clarity and specificity of prompts. Also, it improves overall performance and usability of prompt-based systems
Finally, be curious, explore, experiment, and learn!
## Some common examples
Here are some examples of how you can write a simple prompt and iterate the same once you receive an output
-
Here I first wrote a prompt asking the model to write a function and take an input of time in seconds and convert it to hh:mm:ss format.
After analysing the output, I felt the need to include edge cases in the function and so wrote a prompt asking it to consider all cases and refactor the code
-
Creating JSON to mock any API
(PS: This has been generated in claude.ai)
-
Refactor any code. But do not entirely depend on the output generated by the model, verify the generated code, and use your knowledge to judge if the output shown is better than the one you had written.
-
You can use it to write test cases for any testing library. (Trust me this is a life saver!)
## Conclusion
Will AI replace the work that we do? I do not think at this point of time AI has reached that position where it can do the work of a developer. It is still learning and is very young to do so. I think what we need to understand and practice is how we can use this amazing new technology to make our work better and deliver faster results.

1,894,791 | Async/await and SwiftUI | Using Swift's async/await with SwiftUI can greatly simplify handling asynchronous tasks, such as... | 0 | 2024-06-20T12:28:34 | https://dev.to/ishouldhaveknown/asyncawait-and-swiftui-3b2h | swiftui, async, ios, modular | Using Swift's async/await with SwiftUI can greatly simplify handling asynchronous tasks, such as fetching data from a network. Here's a basic example that includes a view, view model, use-case, repository, and service layer to illustrate how these components interact.
See [my Github project for the tested source-code](https://github.com/ishouldhaveknown/ios-swiftui-asyncawait).
### 1. Service Layer
First, let's define a service layer responsible for fetching data. This could be a simple API service. `APIService` conforms to `APIServiceProtocol` and simulates fetching data from an API.
```swift
import Foundation
protocol APIServiceProtocol {
func fetchData() async throws -> String
}
class APIService: APIServiceProtocol {
func fetchData() async throws -> String {
// Simulate network delay
try await Task.sleep(nanoseconds: 1_000_000_000)
return "Data from API"
}
}
```
### 2. Repository Layer
The repository layer abstracts the data source (service layer) from the rest of the application. `Repository` conforms to `RepositoryProtocol` and uses the `APIService` to get data.
```swift
import Foundation
protocol RepositoryProtocol {
func getData() async throws -> String
}
class Repository: RepositoryProtocol {
private let apiService: APIServiceProtocol
init(apiService: APIServiceProtocol = APIService()) {
self.apiService = apiService
}
func getData() async throws -> String {
return try await apiService.fetchData()
}
}
```
### 3. Use-Case Layer
The use-case layer contains the business logic. In this case, it fetches data using the repository. `FetchDataUseCase` conforms to `FetchDataUseCaseProtocol` and uses the repository to fetch data.
```swift
import Foundation
protocol FetchDataUseCaseProtocol {
func execute() async throws -> String
}
class FetchDataUseCase: FetchDataUseCaseProtocol {
private let repository: RepositoryProtocol
init(repository: RepositoryProtocol = Repository()) {
self.repository = repository
}
func execute() async throws -> String {
return try await repository.getData()
}
}
```
### 4. ViewModel
The view model interacts with the use-case layer and provides data to the view. `DataViewModel` is an `ObservableObject` that handles data fetching asynchronously using the use-case. It manages loading state, data, and potential error messages. Using `async/await` in this way makes the code more readable and easier to follow compared to traditional completion handler approaches. The `@MainActor` attribute ensures that UI updates happen on the main thread.
```swift
import Foundation
import SwiftUI
@MainActor
class DataViewModel: ObservableObject {
@Published var data: String = ""
@Published var isLoading: Bool = false
@Published var errorMessage: String?
private let fetchDataUseCase: FetchDataUseCaseProtocol
init(fetchDataUseCase: FetchDataUseCaseProtocol = FetchDataUseCase()) {
self.fetchDataUseCase = fetchDataUseCase
}
func loadData() async {
isLoading = true
errorMessage = nil
do {
let result = try await fetchDataUseCase.execute()
data = result
} catch {
errorMessage = error.localizedDescription
}
isLoading = false
}
}
```
### 5. View
Finally, the view observes the view model and updates the UI accordingly. `ContentView` observes `DataViewModel` and displays a loading indicator, the fetched data, or an error message based on the state of the view model.
```swift
import SwiftUI
struct ContentView: View {
@StateObject private var viewModel = DataViewModel()
var body: some View {
VStack {
if viewModel.isLoading {
ProgressView()
} else if let errorMessage = viewModel.errorMessage {
Text("Error: \(errorMessage)")
} else {
Text(viewModel.data)
}
}
.onAppear {
Task {
await viewModel.loadData()
}
}
.padding()
}
}
```

1,894,764 | Project Loom: New Java Virtual Threads | Project Loom: New Java Virtual Threads By using Java 21 lightweight threads, developers can create... | 0 | 2024-06-20T12:23:52 | https://codeline24.com/loom-java-21-ligth-weight-threads/ | Project Loom: New Java Virtual Threads
By using Java 21 lightweight threads, developers can create high-throughput concurrent applications with less code, easier maintenance, and improved observability.
For many years, the primary way to propose changes to the Java language and the JVM has been through documents called JDK Enhancement Proposals (JEPs). These documents follow a specific format and are submitted to the OpenJDK website.
While JEPs represent individual proposals, they are frequently adopted as groups of related enhancements that form what the Java team refers to as projects. These projects are named rather randomly, sometimes after things (Loom, where threads are turned into cloth) or places (Valhalla, the fabled hall of Norse mythology) or the technology itself (Lambda).
Project Loom’s main objective is to enhance the capabilities of Java for concurrent programming by offering two key features: efficient virtual threads and support for structured concurrency.
## Java Platform Threads
Every Java program starts with a single thread, called the main thread. This thread is responsible for executing the code within the main method of your program.
Tasks are executed one after another. The program waits for each task to complete before moving on to the next. This can lead to a less responsive user experience if tasks take a long time (e.g., network requests)
Both asynchronous programming and multithreading are techniques used to achieve some level of concurrency in your code, but they work in fundamentally different ways:
Asynchronous Programming focuses on non-blocking execution of tasks. It initiates tasks without waiting for them to finish and allows the program to continue with other work. This doesn’t necessarily involve multiple threads. It can be implemented even in a single-threaded environment using mechanisms like callbacks and event loops.
While asynchronous programming offers advantages, it can also be challenging. Asynchronous calls disrupt the natural flow of execution, potentially requiring simple 20-line tasks to be split across multiple files and threads. This complexity can significantly increase development time and make it harder to understand the actual program behavior.
Multithreading focuses on concurrent execution of tasks. It creates multiple threads, each running its own instructions, allowing them to potentially execute at the same time (depending on available resources). involves multiple threads running concurrently and focuses on dividing and executing tasks truly in parallel.
While Java Virtual Machine (JVM) plays a crucial role in their creation, execution, and scheduling, Java threads are primarily managed by the underlying operating system’s scheduler.
As a result, Creating and managing threads introduces some overhead due to startup (around 1ms), memory overhead(2MB in stack memory), context switching between different threads when the OS scheduler switches execution. If a system spawns thousands of threads, we are speaking of significant slowdown here.
Multithreading offers potential performance benefits, it introduces additional complexity due to thread management and synchronization.
The question that arises is: how to get the simplicity of synchronous operations with the performance of asynchronous calls?
## Why Virtual Threads?
Platform threads are expensive to create because the operating system needs a big chunk of memory just for each thread.
This is because the memory can’t be adjusted, and it all gets used up for the thread’s information and instructions. On top of that, whenever the system needs to switch between threads, it has to move all this memory around, which can be slow.
In addition to above, we have complexity that multiple threads can access and modify the same data (shared resources) simultaneously. This can lead to race conditions, where the outcome depends on unpredictable timing of thread execution.
To simplify things, the easiest way to handle multiple tasks at once in Java seems like assigning each task its own worker. This approach is called “one task per thread”.
However, using such an approach, we can easily reach the limit of the number of threads we can create.
As an example, let’s create a simple maven module in IntelliJ IDEA IDE, called PlatformThreads.
We create a class MyThread creating simple platform thread:
```
package org.example;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.time.Duration;
public class MyThread extends Thread {
Logger logger = LoggerFactory.getLogger(MyThread.class);
public void run(){
logger.info("{} ", Thread.currentThread());
try {
Thread.sleep(Duration.ofSeconds(1L));
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
}
}
```
In the Main class we have a method Create_10_000_Threads
```
package org.example;
public class Main {
public static void main(String[] args) {
Create_10_000_Threads();
}
private static void Create_10_000_Threads() {
for (int i = 0; i < 10_000; i++) {
MyThread myThread = new MyThread();
myThread.start();
}
}
}
```
If we run this program, very quickly we get following console output:
```
[0.854s][warning][os,thread] Failed to start the native thread for java.lang.Thread "Thread-4063"
Exception in thread "main" java.lang.OutOfMemoryError: unable to create native thread: possibly out of memory or process/resource limits reached
at java.base/java.lang.Thread.start0(Native Method)
at java.base/java.lang.Thread.start(Thread.java:1526)
at org.example.Main.Create_10_000_Threads(Main.java:9)
at org.example.Main.main(Main.java:4)
[ERROR] Command execution failed.
```
This simple example shows how difficult it is to achieve “one task per thread” using traditional multithreading.
## Java Virtual Threads
Enter Java Virtual Threads(<a href="https://openjdk.org/jeps/425" target="_blank">JEP 425</a>). Introduced in Java 17 with Project Loom, aim to reduce this overhead by being managed within the JVM itself, potentially offering better performance for certain scenarios.
Lets see for example how we can create virtual threads. We created a module in the same project named VirtualThreads.
```
MyThread class implementing Runnable interface:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.time.Duration;
public class MyThread implements Runnable{
Logger logger = LoggerFactory.getLogger(MyThread.class);
@Override
public void run() {
logger.info("{} ", Thread.currentThread());
try {
Thread.sleep(Duration.ofSeconds(1L));
} catch (InterruptedException e) {
throw new RuntimeException(e);
}
}
}
```
In the main class we have a method that again creates 10 thousand threads, this time virtual ones.
```
package org.example;
public class Main {
public static void main(String[] args) {
Create_10_000_Threads();
}
private static void Create_10_000_Threads() {
for (int i = 0; i < 10_000; i++) {
Runnable runnable = new MyThread();
Thread vThread = Thread.ofVirtual().start(runnable);
}
}
}
```
Creating a new virtual thread in Java is as simple as using the Thread.ofVirtual() factory method, passing an implementation of the Runnable interface that defines the code the thread will execute.
This time the program successfully executes with no error.
Unlike Platform Threads, Virtual Threads are created in Heap memory, and assigned to a Carrier Thread (Platform) only if there is work to be done.
**Virtual threads Architecture**
This way we can create many virtual threads with very low memory footprint and at the same time ensure backward compatibility.
It’s important to note that Project Loom’s virtual threads are designed to be backward compatible with existing Java code. This means your existing threading code will continue to work seamlessly even if you choose to use virtual threads.
In traditional java threads, when a server was waiting for a request, the operating system was also waiting.
Since virtual threads are controlled by JVM and detached from the operation system, JVM is able to assign compute resources when virtual threads are waiting for response.
This significantly improves the efficiency of computing resource usage.
This new approach to concurrency is possible by introducing something called continuations and structured concurrency.
Continuation is a programming technique that allows a program to pause its execution at a specific point and later resume at the same point, carrying the necessary context.
The continuation object is used to restore the thread’s state, allowing it to pick up exactly where it left off without losing any information or progress
Structured concurrency(<a href="https://openjdk.org/jeps/453" target="_blank">JEP 453</a>) aims to provide a synchronous-style syntax for working with asynchronous tasks. This approach simplifies writing basic concurrent tasks, making them easier to understand and express for Java developers.
Structured concurrency simplifies managing concurrent tasks by treating groups of related tasks across different threads as a single unit. This approach makes error handling, cancellation, reliability, and observability all easier to manage.
Project Loom’s innovations hold promise for various applications. The potential for vastly improved thread efficiency and reduced resource needs when handling multiple tasks translates to significantly higher throughput for servers. This translates to better response times and improved performance, ultimately benefiting a wide range of existing and future Java applications. | jusufoski | |

Welcome towards the global globe of recycling! Recycling is a real way of reusing materials so they really do not head to waste. Recycling helps us lessen the pollution and make our environment cleaner and safer. One of the actual ways to recycle is by using a PET recycling machine we will explore the advantages of employing a PET recycling machine, how it really works, how exactly to utilize it, and the ways that are numerous can be applied
Benefits:
A PET recycling machine is made for plastic recycling. PET synthetic is used to make things like water containers, soda bottles, and food packaging. The advantage of using a PET recycling machine is so it can turn waste that is plastic plastic flakes or pellets. These flakes or pellets are able to be used to make new plastic recycling machine items like carpets clothing, and other items that are plastic. Employing a PET recycling machine also means less synthetic waste going to landfills, reducing pollution and keeping our planet cleaner
Innovation:
PET devices that are recycling part of modern technology. They use higher level procedures to turn plastic into flakes or pellets. These machines utilize high-tech sensors that detect the caliber of the plastic being processed. The technology in these machines is continually increasing, which means better recycling procedures and better quality items that are recycled
Security:
PET machines that are recycling generally safe to use. They've been designed to have safety features that prevent accidents. The machines have actually shields to cover the cutting blades, and safety hair that prevent the equipment from running if any such thing goes wrong. People who use these devices are trained to check out safety procedures to make sure that they do not get hurt
Just how to Use:
A PET recycling machine is user friendly. The waste that is plastic loaded into the equipment, and the equipment does the remainder. The plastic is cut into small pieces, which are then washed with water to remove any impurities. The plastic is then cooled and melted to create pellets or flakes. The pellets or flakes are then ready for use in creating plastic granulator products that are brand new
Service:
PET machine that is recycling providers offer after-sales services. This consists of things like maintenance repair, and replacement of parts. They offer customer assistance and support. The service providers are available to assist if there are any dilemmas or issues with the machine
Quality:
animal recycling pellets that are machine-produced flakes are of high quality. This is because discarded plastic undergoes a procedure that is thorough of and refinement before they are turned into flakes or pellets. The flakes or pellets created using these devices are regarding the plastic granulators quality that is same virgin synthetic. They can be used to create products that are new are equally as good as those produced from virgin plastic
Application:
animal machines that are recycling be used in various industries, including the textile, automotive, and construction industry. These machines are able to turn waste that is plastic polyester fibers found in textiles and upholstery. They could also be used in the manufacturing of car components, like bumpers and dashboards. In the construction industry, recycled plastic enables you to create insulation materials, roof tiles, and pipes

1,894,098 | My Journey so far as a developer | Hey there fellow devs, I will like to use this post to share my journey so far as a developer. It's... | 0 | 2024-06-20T12:22:54 | https://dev.to/kansoldev/my-journey-so-far-as-a-developer-4d23 | Hey there fellow devs, I will like to use this post to share my journey so far as a developer. It's sort of a review of how far I have come, and the next steps I am looking to take. Hope you find it interesting and insightful, let's get into it!
I started coding when I was 13 years old, precisely 2013, but I started getting serious with coding in 2017. I didn't have any problem with HTML and CSS, but I realized I was using old courses and tutorials to learn Javascript, and this totally destroyed my motivation to continue learning how to code. I just felt like "Yeah this field isn't for me, I just can't do this anymore!". Most of us feel this way, and trust me all I wanted to do at that point was quit and never go back writing a single line of code again. Surprisingly, something happened to me, I taught to myself that **"Yes I have been doing this all wrong, but rather than quit, let me retrace my steps back and start doing things right"**, what a mindset shift that has kept me programming till date!. When I made up my mind to start afresh and do things differently, I came across Brad Traversy's [Youtube channel](https://www.youtube.com/@TraversyMedia), and thanks to him, I was able to get myself back on track with JS and learn the fundamentals properly, I really owe part of not giving up on programming to him.
About late 2020 in December, I got a Job!, my first ever gig since learning how to code, I am still on that project up till now (4 years people building 1 Web Application!!, I am tired at this point). I didn't have any experience doing work for a client, and I was desperately looking for money and work to prove to myself that I have what it takes to be a developer. The project is a Real Estate Application built with HTML, CSS, SASS, JS, PHP and MySQL (and I mean custom PHP by the way, no framework, young me didn't know any better then). Here is a link to the website, let me know what you think - [HMG Homes](https://www.hmghomes.com/).
When the year 2021 came, I kept on improving my skills as a front end developer, I even learnt MySQL from a course I bought on Udemy by Colt Steele (A great instructor by the way 😉). I regret not documenting what I had been learning along the way, this was a huge lesson I got to learn when I joined Tech Twitter (or Tech X lol), and that's why most tech people will advice you to document your learning as you go, it doesn't only help you build an audience but shows you where you came from, which can be a source of encouragment. Around July/August, I got into an internship called HNG Internship which runs every year, it is less of an internship, and more of a competition with 10 stages, I stopped at stage 6, and couldn't continue because of light issues in my area and data (People in Nigeria will understand what I mean). The internship helped me improve my skills and more importantly collaborate with other developers which is a vital skill to learn as a developer. The reason why I hardly ever documented what I did was because I was afraid of putting myself out there, like what will people think of me?, I failed to realize that documenting is more for yourself than other people, you build up a reference that your future self can go back to which can be very helpful. Austin Kleon said in his book (Show Your Work) that **"Be a documentarian of your work"** and **"You can be the best at what you do, but if no one knows you exists, it won't really matter"**.
The year 2022 came and I was really trying to see how to make money as a developer. The real estate client I am working for will just be sending me money whenever he feels like, as if he is doing me a favor (imagine), but it's kind of what I signed up for right?, you truly learn lessons from experience. I later on got a Job to build a React application for an NFT company which paid me ₦80,000 ($52 as of now) which to me at the time was a lot, for someone looking for money. The project couldn't be completed as the client wasn't all that serious with the application, and the url as of this writing isn't working again, good thing I got the money but I won't be able to show that application to potential employers as real world experience. So my problem mainly is that I have some form of experience, I have built some good projects, but it looks like I don't have experience at all 😂😂, this is why I said earlier that I wish I did a lot of documentation when I was still early on in this Journey, it's actually a bit harder when you know you have done stuff, but it's like there is nothing to show for it (I like to know if you ever being in this position, and what you did)
Fast track to 2023, I didn't get any side gig this year, but I started looking towards getting a full time Job, as freelancing was not as easy as people painted it to be, cash in today, no cash for the next 5 months, I even tried Upwork and Fiverr but they didn't just work for me (Or I didn't try hard enough). I also tried growing an audience on X but inconsistency kept leaving me discouraged, I will start today and stop in the next 3 days, this kept on going until I finally decided to just leave it for the main time. Another lesson I learnt along the way is to be consistent with doing something, no matter the current results you see, you have to stick with it for long to see any tangible results.
Currently in 2024, I am working on getting a Job as a frontend developer, specifically with React. As for my progress so far, I am building projects from Frontend Mentor platform, my current project is the age calculator app. I am working on my portfolio and resume and also trying to be consistent with building my personal brand on X (I am also trying to build my brand on Linkedin but I want to focus on 1 platform for now), consider following me on X @Kansoldev. I believe it's not only me, as there seems to be too much to learn this days, it makes you feel like you have not even started, Front end development has really changed over the past few years, but nonetheless it's worth it if you can stick with it.
Thank you for sticking around, and reading this if you got to the end. Being a software developer is a long term commitment, but has a lot of benefiting rewards, afterall nothing good comes easy, everything good takes time to show, so keep pushing. You can follow me on [X](https://x.com/Kansoldev) for more dev tips and insights. | kansoldev | |

It... | 0 | 2024-06-20T12:17:10 | https://dev.to/astpp/combat-caller-id-spoofing-stir-shaken-voip-strategies-to-trace-and-reduce-nuisance-calls-4bnb | stirshaken | Caller ID spoofing has become a significant nuisance for businesses and individuals alike. It involves falsifying the caller ID to disguise the caller's true identity, which leads to various fraudulent activities and unwelcome interruptions. STIR/SHAKEN (Secure Telephone Identity Revisited/Signature-based Handling of Asserted Information Using toKENs) is a set of standards designed to combat this issue, especially for VoIP (Voice over Internet Protocol).
In this article, we will explore how **[STIR SHAKEN VoIP solutions](https://astppbilling.org/stir-shaken-solution/)** can help trace and reduce nuisance calls, providing effective strategies for implementation.
Undoubtedly, the integration of STIR/SHAKEN open source solutions is crucial in today's communication landscape. These technologies significantly enhance the ability to verify and authenticate caller ID information, thus reducing the prevalence of spoofed calls.
## Understanding STIR/SHAKEN VoIP
STIR/SHAKEN is a framework aimed at authenticating and verifying caller ID information for VoIP calls. STIR involves protocols for signing and verifying the identity of the caller, while SHAKEN defines how these protocols are deployed within the VoIP network. This technology significantly reduces the ability of spammers and scammers to manipulate caller ID information.
Undoubtedly, the STIR/SHAKEN open source or proprietary framework enhances trust in communication networks by ensuring the accuracy of caller identification. It achieves this by attaching a digital certificate to each call, which validates the caller's identity. When a call is received, the recipient's network can check this certificate to confirm the authenticity of the caller ID. This process makes it difficult for scammers to disguise their identity, thus reducing the number of fraudulent calls.
## Importance of STIR/SHAKEN in VoIP
The integration of STIR SHAKEN VoIP solutions is crucial for several reasons. Firstly, it helps in verifying the legitimacy of incoming calls, thereby reducing the number of spoofed calls. Secondly, it enhances trust in communication networks by providing accurate caller identification. Moreover, businesses can ensure that their outgoing calls are authenticated, maintaining their reputation and credibility.
Furthermore, the implementation of STIR/SHAKEN open source enhances overall network security. Ensuring that all calls are properly authenticated, prevents unauthorized access and reduces the risk of fraudulent activities. In addition, it supports regulatory compliance, as many regions now mandate the use of caller ID authentication technologies to protect consumers from spoofing.
### Implementing STIR/SHAKEN Protocols
Deploying STIR SHAKEN VoIP protocols is essential for any business aiming to combat caller ID spoofing. These protocols work by authenticating and verifying caller ID information before it reaches the recipient. Each call gets a digital signature that validates the caller's identity, making it difficult for spammers to spoof numbers. Undoubtedly, implementing these protocols adds a robust layer of security to your communication system.
#### Utilizing Advanced Call Analytics
Advanced call analytics are powerful tools for tracing the origin of nuisance calls. These analytics examine call patterns and identify anomalies that indicate suspicious activities. By analyzing data such as call duration, frequency, and geographical location of calls, businesses can detect and trace fraudulent calls more efficiently. Moreover, these tools allow businesses to take proactive measures, such as blocking suspicious numbers and flagging potential threats.
#### Collaborating with VoIP Providers
Working closely with VoIP providers can significantly enhance the effectiveness of STIR SHAKEN VoIP implementations. Providers often have additional tools and resources to help trace and block spoofed calls. Furthermore, VoIP providers can offer valuable insights and technical support, ensuring that the STIR/SHAKEN protocols are correctly integrated and functioning optimally. This collaboration ensures a more comprehensive approach to combating caller ID spoofing.
#### Educating Employees and Customers
Along with using STIR/SHAKEN open source, educating employees and customers about caller ID spoofing can significantly reduce its impact. Awareness programs can teach them how to recognize and respond to suspicious calls. Equally important, employees should be trained on the proper procedures to follow when they encounter spoofed calls. Educating customers on the signs of spoofing and encouraging them to report suspicious calls can also help in tracing and reducing these nuisance calls.
#### Regularly Updating Security Protocols
Keeping security protocols up to date is crucial for maintaining effective protection against spoofing tactics. Regular updates and maintenance ensure that your communication systems remain secure and resilient against new spoofing methods. Ultimately, staying ahead of potential threats by continuously updating your security measures helps maintain the integrity and reliability of your communication infrastructure.

1,894,773 | How Do Shell Commands Function? | The Role of the Shell: Bridging User Input and Command Execution in Linux Shell is a program that... | 27,789 | 2024-06-20T12:16:16 | https://waywardquark.hashnode.dev/how-shell-commands-work | linux, shell, webdev, beginners | **The Role of the Shell: Bridging User Input and Command Execution in Linux**
Shell is a program that takes user inputs and passes them to the operating system. It provides an interface to accept commands and their arguments, invokes system calls, and runs other programs.
A Terminal program, such as iTerm2, is a GUI that interacts with the shell, such as Z shell. It accepts text commands and displays the output.
The above screenshot is from a terminal with a shell process in ready state, waiting for a user to enter a command through the keyboard.
Once the user types above command and hits the enter key, the shell searches a file named "`cat`" through a list of directories stored in `$PATH` environment variable, separated by "`:`" .
In our case, the file "`cat`" is stored in the directory "`/usr/bin`". The contents of the "`/usr/bin`" directory, as shown in the screenshot below, include the "`cat`" file. In Linux, we have files and processes. When "`cat`" is executed, a process is created with a unique number called a **PID**. This **PID** is used by system calls and other processes.
Now the shell executes the "`cat`" command and creates a child process. The shell process acts as the parent process for the new process created by executing the "`cat`" command.
After executing the "`cat`" command, the shell returns to the ready state to accept a new command. | wayward_quark |
1,894,772 | How to Write Your First Cypress Test [With Examples] | Choosing an ideal testing framework, especially with a different technology stack, can be challenging... | 0 | 2024-06-20T12:16:15 | https://www.lambdatest.com/blog/cypress-test/ | cypress, beginners, tutorial, programming | Choosing an ideal testing framework, especially with a different technology stack, can be challenging for new users, particularly those switching from other testing tools to Cypress. This shift might involve adapting to unfamiliar technological stacks. However, Cypress addresses this challenge by providing an in-built tool called ‘Cypress Studio’.
There are two ways to write your first Cypress test:
1. Using ‘Cypress Studio’
2. Writing your script
In this blog, we will discuss how a new user can start his journey in Cypress and efficiently write the first Cypress test. You will also see the implementation of Cypress tests on local machines and cloud grids.
## What is Cypress Studio?
Cypress Studio provides a user-friendly interface for test case creation. It is a record and playback tool that captures user interactions with the application being tested. Using Cypress Studio, you can record user interactions in JavaScript. Whatever the step you follow in UI, Cypress Studio automatically records the steps in the backend in the test file
Here are some benefits of using Cypress Studio:
* **Record and Playback**
The interface supports a record-and-playback mechanism, allowing users to record their interactions with the application. This feature is particularly useful for users who may not have extensive programming knowledge, enabling them to create [test scripts](https://www.lambdatest.com/learning-hub/test-scripts?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub) without manually writing code.
* **Codeless Test Automation**
One of the primary advantages of Cypress Studio is its codeless approach. Users can create and edit test scripts without writing code, making it accessible to individuals with limited programming knowledge. This lowers the entry barrier for manual testers and non-developers to participate in [test automation](https://www.lambdatest.com/automation-testing?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage).
* **Reduce Learning Curve**
The simplicity and clarity of Cypress Studio’s interface reduce the learning curve for users new to [automated testing](https://www.lambdatest.com/learning-hub/automation-testing?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub). This enables teams to onboard new members quickly and encourages broader team participation in the testing process.
* **Fast Script Creation**
Cypress Studio records all the steps of UI interaction so if someone wants to create the script fast he/she can record the script and can re-use the record script for further development.
* **Debugging the script**
[Debugging ](https://www.lambdatest.com/learning-hub/debugging?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub)in Cypress Studio involves examining and modifying the recorded script to ensure it accurately reflects the intended test scenario. Users can edit and debug the recorded script. This flexibility allows users to tweak tests as needed, which strikes a balance between codeless development and human scripting.
{% youtube 7CYgItuHq5M %}
In the next section, you will see how we can set up Cypress Studio.
> [**Test website on different browsers](https://www.lambdatest.com/test-website-on-different-browsers?utm_source=hashnode&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage) like Chrome, Safari, Firefox, and Opera for free on LambdaTest platform. Easily test on 3000+ desktop & mobile environments.**
## Setting up Cypress Studio
Before setting up Cypress Studio, you need to install Cypress. You can install Cypress using the following commands:
npm install cypress --save-dev
or
yarn add cypress --dev
In the screenshot below, you can see that the latest version of Cypress has been installed. However, when writing this blog on your first Cypress test, Cypress’s latest version was 13.6.2.
The next step is to enable Cypress Studio. To enable this feature, we must set *experimentalStudio:true* in the configuration file.
const { defineConfig } = require("cypress");
module.exports = defineConfig({
e2e: {
experimentalStudio:true,
setupNodeEvents(on, config) {
// implement node event listeners here
},
},
});
We have updated the *cypress.config.js* (configuration file)to enable the Cypress Studio feature. Now, the next step is to record the script.
## Ways of Recording the Script
We can record the script using Cypress Studio. Below are two options to record the script:
* Create a test with Cypress Studio
* Add New Test
## Using the ‘Create test with Cypress Studio’ Option
You should have some existing [test cases](https://www.lambdatest.com/learning-hub/test-case?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub) before recording using the option ‘*Create test with Cypress Studio*’ in Cypress Runner.
Let’s run the following command to open [Cypress Runner](https://www.lambdatest.com/blog/cypress-cli-and-test-runner/?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=blog).
yarn cypress open
After opening the Cypress Runner, run an existing test case. As we run the command, it will open Cypress Runner with the option ‘*Create test with Cypress Studio.*’
Clicking on the ‘*Create test with Cypress Studio*’ link in the Cypress Test Runner initiates Cypress Studio and prompts you to provide the URL of the application you want to test.
Let’s record the test scenario below.
1. Open the site [https://ecommerce-playground.lambdatest.io/](https://ecommerce-playground.lambdatest.io/?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage).
2. Click on My Account.
3. Enter User Name.
4. Enter Password.
5. After logging in, log out of the application.
Once we record the above scenario, we will be asked to save the recorded commands.
Let’s save the command that is recorded by providing the recorded script’s name.
Once we save the recorded script, it is automatically saved under the path *‘e2e/LTCypressStudio’*. This path indicates the location within your Cypress project where the test script file is stored.
Below is the recorded script where you can see the generated code. Once the recording is done, it will end with line /*==== End Cypress Studio ==== */
describe('Cypress Studio Recorded Script', () => {
/* ==== Test Created with Cypress Studio ==== */
it('LTCypressStudio', function() {
/* ==== Generated with Cypress Studio ==== */
cy.visit('https://ecommerce-playground.lambdatest.io/');
cy.get('#widget-navbar-217834 > .navbar-nav > :nth-child(6) > .nav-link > .info > .title').click();
cy.get('#input-email').clear('lambdatestnew@yopmail.com');
cy.get('#input-email').type('lambdatestnew@yopmail.com');
cy.get('#input-password').clear();
cy.get('#input-password').type('Password1');
cy.get('form > .btn').click();
/* ==== End Cypress Studio ==== */
})
})
We have seen above one option to record the script by clicking on the link *‘Create test with Cypress Studio’* from Cypress Runner.
Let’s see the second option, i.e., ‘Add New Test’ to record the script.
> **Dive into the world of [XPath Tester](https://www.lambdatest.com/free-online-tools/xpath-tester?utm_source=hashnode&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=free_tool) to streamline your web scraping and automation projects. Discover its features, uses, and best practices for optimal performance.**
## Adding New Test
This option is used when you want to create a completely new Cypress test. It lets you define and execute specific [test scenarios](https://www.lambdatest.com/learning-hub/test-scenario?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub) in a new file.
As we click on ‘Add New Test,’ it will ask us to enter the URL. Let’s record the scenario below.
1. Open the site [https://www.lambdatest.com/selenium-playground/auto-healing](https://www.lambdatest.com/selenium-playground/auto-healing?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage).
2. Enter User Name.
3. Enter Password.
4. Click on the Submit button.
After recording, click Save Commands. Let’s give the name ‘LambdaTestAddNewTest.’
Once we save the script by giving some name, the test case executes and passes successfully. Below is the recorded script by Cypress Studio.
/* ==== Test Created with Cypress Studio ==== */
it('https://www.lambdatest.com/selenium-playground/auto-healing', function() {
/* ==== Generated with Cypress Studio ==== */
cy.visit('https://www.lambdatest.com/selenium-playground/auto-healing');
cy.get('#username').clear();
cy.get('#username').type('LambdaTest');
cy.get('#password').clear();
cy.get('#password').type('Test@1234');
cy.get('form > .flex > .bg-black').click();
/* ==== End Cypress Studio ==== */
});
## Modifying the Existing Script
Using Cypress Studio, we can add new scripts and update the existing script with more commands.
**Add Commands to Test**
This option is useful when adding Cypress commands to an existing test. It allows you to extend the functionality of an already defined test or modify its behavior by incorporating additional Cypress commands.
Let’s update one of the previously recorded scripts where we are login into [https://ecommerce-playground.lambdatest.io/](https://ecommerce-playground.lambdatest.io/?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage)
it('LTCypressStudio', function() {
/* ==== Generated with Cypress Studio ==== */
cy.visit('https://ecommerce-playground.lambdatest.io/');
cy.get('#widget-navbar-217834 > .navbar-nav > :nth-child(6) > .nav-link > .info > .title').click();
cy.get('#input-email').clear('lambdatestnew@yopmail.com');
cy.get('#input-email').type('lambdatestnew@yopmail.com');
cy.get('#input-password').clear();
cy.get('#input-password').type('Lambda123');
/* ==== End Cypress Studio ==== */
})
Cover the below scenario to update the existing script using Cypress Studio.
1. After logging in, search for the text ‘HP.’
2. Click on the first item in the search results.
3. Click on Add to Cart.
4. Click on View Cart.
Click on ‘Add Commands to Test’ from Cypress Runner.
As part of Cypress Studio, when we click ‘Add Commands to Test,’ the complete test case is rerun. In our case, the user is logged in to the site. After that, we can search for the product ‘HP,’ add it to the cart, and redirect to the View Cart page.
The Cypress command log shows that each updated step is recorded with the ‘Save Commands’ button. Once you click the ‘Save Commands’ button, the script is updated with more steps.
The screenshot below shows that once the scenario is completed, the script will be updated with some more steps. You can see some more steps are added, so you can update the existing script using Cypress Studio. Below is the script that is recorded.
Cypress Studio is beneficial for those seeking to swiftly generate test scripts without needing to code, making it especially advantageous for novices getting started with Cypress.
Despite being a handy tool for rapidly creating code-free test scripts, Cypress Studio encounters difficulties when handling intricate test scenarios or scenarios incorporating dynamic data.
So far, we have seen how you can record scripts using the built-in tool Cypress Studio. In the next section, you will see how we can create a Cypress test case by writing our script.

Perfect for quick debugging and testing. Try for free now!**
## Writing First Cypress Test Script
Writing Cypress scripts manually refers to crafting test code directly using JavaScript or TypeScript rather than relying on visual recording tools like Cypress Studio. Cypress uses [Mocha](https://www.lambdatest.com/mocha-js?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage) as its default [automation testing framework](https://www.lambdatest.com/blog/automation-testing-frameworks/?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=blog).
When you install Cypress, it automatically includes Mocha, and you don’t need to install Mocha separately to use it with Cypress. Integrating Mocha with Cypress provides a structured and organized way to write end-to-end tests. Cypress leverages Mocha’s syntax, which includes *describe* and *it* blocks for test organization, as well as hooks for setup and teardown, to create a clear and readable testing structure.
Before writing the script, we need to set up Cypress. Below are some of the steps that we have to follow.
## Step 1: Install Cypress
To write the script on your own, let’s set up Cypress using the following commands:
npm install cypress —-save-dev
or
yarn add cypress —-dev
The screenshot below shows that Cypress’s latest version was 13.6.2 when this blog on writing your first Cypress test was written.
After installation, the folder structure looks like the one below, with different folders given in brief detail below.
The table below summarizes the purpose of each directory and file within the Cypress project.
## Step 2: Create a Test File
Create a new test file under cypress/e2e/ to run the e2e test case. Let’s give a name to the file, e.g., *lambdatest_test_spec.cy.js*
## Step 3: Write Your Test
As we mentioned above, Cypress supports the Mocha framework. Therefore, we must grasp key concepts before proceeding to our initial script.
**describe() Block**
Mocha uses the *describe* and *it* blocks to structure test suites and individual test *cases.describe()* is used to group tests.
**it() Block**
*it()* is used to define individual test cases.
**Hooks**
Mocha supports hooks such as *before(), beforeEach(), after(),* and *afterEach()*. Cypress utilizes these hooks for setup and teardown tasks, like preparing the [test environment ](https://www.lambdatest.com/blog/what-is-test-environment/?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=blog)and cleaning up before running tests.
**Assertions**
Mocha itself doesn’t include built-in assertion libraries. Cypress, however, provides its assertion library and extends Mocha with Chai assertions. Cypress uses Chai assertions to assert conditions in your tests.
Some of the Examples are *.should(‘have.text’, ‘Expected Text’),.should(‘not.equal’, ‘Expected Text’),.should(‘exist’),.should(‘not.be.disabled’), .should(‘have.class’, ‘active’),* etc.
**Excluding the Tests**
You can use the *.skip()* method to exclude a specific Cypress test. This method can be applied to a Cypress test or a *description* block.
**Excluding the Tests**
You can use the *.skip()* method to exclude a specific Cypress test. This method can be applied to a Cypress test or a *description *block.
The *describe.skip()* function in Cypress is used to skip the entire [test suite](https://www.lambdatest.com/learning-hub/test-suite) within the *describe *block. Here’s an example:
**Including the Tests**
You can use the *.only() *method to run only specific tests or test suites during the [test execution](https://www.lambdatest.com/learning-hub/test-execution?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub). When you use *.only *on a Cypress test or a suite, only that test or suite will be executed, and all other tests without *.only* will be skipped.
So far, we have discussed some concepts required of a user writing his script for the first time. Let’s now put that knowledge into practice by crafting a simple Cypress Script.
Let’s write the script for the below scenario.
1. Open the URL [https://ecommerce-playground.lambdatest.io/index.php?route=account/login](https://ecommerce-playground.lambdatest.io/index.php?route=account/login?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage).
2. Enter Email.
3. Enter Password.
4. Click on the Login button.
5. Search product ‘VAIO.’
6. Click the first product from the search result.
7. Verify that the searched product name should contain the text ‘Sony VAIO.’
Open *lambdatest_test_spec.cy.js* and write a simple Cypress test to visit a website, log in, and search for the product.
/// <reference types="cypress" />
describe("Lambdatest Login ",() => {
it("Open the URL", () => {
cy.visit(
"https://ecommerce-playground.lambdatest.io/index.php?route=account/login"
);
});
it("Login into the application", () => {
cy.get('[id="input-email"]').type("lambdatest@yopmail.com");
cy.get('[id="input-password"]').type("lambdatest");
cy.get('[type="submit"]').eq(0).click();
});
it("Search the Product", () => {
cy.get('[name="search"]').eq(0).type("VAIO");
cy.get('[type="submit"]').eq(0).click();
});
it("Verify Product after search ", () => {
cy.contains("Sony VAIO");
});
});
> **Accessibility DevTools Chrome Extension redefines the standards of web [accessibility testing chrome](https://www.lambdatest.com/accessibility-devtools?utm_source=hashnode&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=webpage), your go-to Chrome extension on for developers, testers, and designers.**
**Code Walkthrough**
Let’s do a code walkthrough to understand the script in detail.
**describe Block**
*describe(“LambdaTest Login”, () => { … }):* This block represents a test suite named ‘Lambdatest Login’ that contains multiple Cypress test cases related to the LambdaTest login functionality**.**
**Open the URL**
Visit the specified URL, which is the login page of the LambdaTest application.
**Login into the application**
Enter the Email and Password input fields, enter the respective values, and click the Login button.
In the script, we used different [locator strategies](https://www.lambdatest.com/learning-hub/selenium-locators?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub) to interact with elements on the web page. Locators identify and target HTML elements, allowing Cypress to perform actions like typing text, clicking buttons, etc.
Here is the detail of each locator used here:
***[id=”input-email”]*:** Targets the input element with the *ID* attribute set to “*input-email*.”
***[id=”input-password”]*:** This function targets the input element with the *ID* attribute set to “*input-password*.”
***[type=”submit”]*:** This function targets the Submit button(s). The *.eq(0)* selects the first matching button.
**Search the Product**
You can search the data by entering a value in the input field, ‘VAIO,’ and clicking the Search button.
***[name=”search”]*: **This function targets the input element with the *name *attribute set to “search.”
***[type=”submit”]*: **This function targets the Submit button(s). The *.eq(0)* selects the first matching button.
**Verify Product after search**
Verifies that the search results page contains the text “Sony VAIO.”

## Step 4: Execute the Test Case
There are different ways of executing the Cypress test cases.
* **Headed mode**: where we can see all executing steps in the browser window.
* **Headless mode**: where we execute tests without loading a complete web browser.
### Running Test in Headed Mode
To execute the Cypress test case in the headed mode locally, we must run the following command:
yarn cypress open
or
npx cypress open
As we run the command, it will open the below screen.
There are two options: E2E testing and Component Testing.
[E2E Testing](https://www.lambdatest.com/learning-hub/end-to-end-testing?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub): E2E testing allows users to simulate user interactions, navigate through the application, and validate the application’s behavior as a whole.
[Component Testing](https://www.lambdatest.com/learning-hub/component-testing?utm_source=devto&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub): Component testing focuses on testing individual application components in isolation. Component testing aims to verify that each application part behaves as expected independently of the other components.
Select E2E Testing from the above screenshot, then select the desired browser for testing. Finally, launch the Cypress Runner to initiate the testing environment.
Click on ‘lambdatest_test_spec.cy.js’ to start executing the tests, and finally, you will see all test steps passed.

Master the essentials to begin your Selenium Java testing journey confidently.**
### Running Test in Headless Mode
By default, Cypress runs in ‘headless mode,’ where the browser runs in the background without opening a visible browser window.
The command to run the Cypress test case in headless mode is:
yarn cypress run
or
npx cypress run
The screenshot below shows that all test cases are executed successfully in a headless browser.
There are some other commands that you can use to execute the test cases.
**Run a full test present in the e2e folder in the Headless mode:**
Use the command:
npx cypress run
or
yarn cypress run
**Run a particular test case on the default browser in the Headless browser:**
The default browser is Electron when you run test cases in headless mode. Use the following command to execute a particular test case on the default browser:
npx cypress run --spec "cypress/e2e/lambdatest/lambdatest_test_spec.cy.js"
> **Selenium [WebDriver](https://www.lambdatest.com/learning-hub/webdriver?utm_source=hashnode&utm_medium=organic&utm_campaign=june_20&utm_term=bh&utm_content=learning_hub): Automate browser activities locally or remotely. Explore Selenium components, version 4, and its pivotal role in automated testing**
**Execute test case on a particular browser in the Headless mode:**
Use the following command to execute a specific test case on a particular browser. In this case, we are running on the Chrome browser in headless mode.
npx cypress run --browser chrome --spec "cypress/e2e/lambdatest/lambdatest_test_spec.cy.js"
So far, we have explored creating a test script using Cypress Studio and saw how to write the script manually. We have also reviewed different approaches for running these test cases in a local environment. Now, let’s see how we can execute the test cases in the cloud.
Running Cypress test cases in the cloud has various benefits. Cloud-based testing platforms provide scalability, allowing you to scale your testing infrastructure based on the project’s needs. They also enable parallel testing, allowing you to run multiple tests concurrently.
There are various cloud-based platforms in the market. LambdaTest emerges as a standout choice.

In the fast-paced world of software development, ensuring both speed and quality is paramount. [Automated regression testing](https://keploy.io/regression-testing) stands as a crucial tool in achieving this delicate balance. It not only accelerates the testing process but also enhances accuracy and reliability, thereby enabling teams to deliver high-quality software at a rapid pace.
Understanding Regression Testing
Before delving into automated regression testing, it’s essential to grasp the concept of regression testing itself. In software development, regression testing verifies that recent code changes have not adversely affected existing functionalities. It ensures that previously developed and tested software still performs correctly after a change or addition. This iterative process helps maintain the integrity of the software, preventing unintended consequences from slipping into production.
The Role of Automation
Automation in regression testing involves using specialized tools to execute test cases, compare actual outcomes with expected outcomes, and report differences automatically. Unlike manual regression testing, which can be time-consuming and error-prone, automation offers several key benefits:
1. Speed and Efficiency: Automated tests can be executed much faster than manual tests, allowing for quicker feedback on code changes. This acceleration is particularly valuable in agile and continuous integration/continuous deployment (CI/CD) environments, where rapid iterations are the norm.
2. Repeatability: Automated tests can be run consistently, ensuring that every test cycle produces identical results under the same conditions. This consistency helps in detecting even subtle deviations that might indicate potential issues.
3. Coverage: Automation enables broader test coverage by facilitating the execution of a large number of test cases across different environments and configurations. It helps in testing various scenarios that might be impractical or impossible to cover manually.
4. Resource Optimization: By reducing the reliance on manual effort, automation frees up valuable human resources to focus on more creative and complex testing tasks, such as exploratory testing and test strategy refinement.
Implementing Automated Regression Testing
Implementing automated regression testing involves a structured approach to ensure effectiveness and reliability:
1. Test Selection: Identify which test cases are suitable candidates for automation. Typically, tests that are repetitive, time-consuming, critical for business functionality, or prone to human error are prioritized for automation.
2. Tool Selection: Choose appropriate tools and frameworks based on the technology stack, testing requirements, and team expertise. Popular automation tools include Selenium for web applications, Appium for mobile apps, and JUnit/TestNG for unit testing.
3. Script Development: Develop automated test scripts that simulate user interactions with the software. These scripts should be modular, maintainable, and reusable to accommodate changes in the application over time.
4. Environment Setup: Set up a dedicated testing environment that mirrors production as closely as possible. This ensures that tests accurately reflect real-world usage scenarios and dependencies.
5. Integration with CI/CD: Integrate automated regression tests into the CI/CD pipeline to enable continuous testing. This integration allows for early detection of defects and ensures that only thoroughly tested code reaches production.
6. Monitoring and Maintenance: Regularly monitor automated test results and maintain test scripts to keep pace with evolving application features and changes. Continuous improvement ensures that automated tests remain effective and reliable.
Benefits of Automated Regression Testing
The adoption of automated regression testing brings significant advantages to software development teams:
• Faster Time-to-Market: By reducing testing cycles and accelerating feedback loops, automated regression testing helps shorten the time required to release new features or updates.
• Improved Quality: Automated tests detect defects early in the development lifecycle, reducing the likelihood of critical issues reaching production and improving overall software quality.
• Cost Efficiency: While there is an initial investment in automation tools and setup, the long-term benefits include lower testing costs, reduced rework, and minimized operational risks.
• Enhanced Confidence: Stakeholders gain confidence in the software’s reliability, knowing that changes are thoroughly validated through automated regression testing.
Challenges and Considerations
Despite its numerous benefits, automated regression testing also presents challenges that teams must address:
• Initial Setup Complexity: Implementing automation requires upfront investment in tool selection, script development, and environment configuration.
• Maintenance Overhead: Test scripts need regular updates to adapt to changes in the application, potentially increasing maintenance effort.
• Test Data Management: Ensuring the availability and integrity of test data sets can be challenging, especially in complex testing scenarios.
• Skill Requirements: Automation testing demands specialized skills and expertise, which may require training or hiring dedicated resources.
Conclusion
In conclusion, automated regression testing serves as a cornerstone of modern software development practices, enabling teams to deliver high-quality software efficiently and reliably. By automating repetitive and time-consuming testing tasks, teams can focus on innovation and strategic testing initiatives. However, successful implementation requires careful planning, proper tool selection, and ongoing maintenance to maximize its benefits. As technology evolves, automation will continue to play an increasingly crucial role in ensuring the agility, quality, and competitiveness of software products in the market. | keploy |
1,890,294 | Isolating user data logic with a UserService | Introduction In this article, I'll shift the focus to refactor the user data management.... | 27,664 | 2024-06-20T12:08:44 | https://dev.to/cezar-plescan/refactoring-user-data-service-nop | angular, tutorial, refactoring, services | ## Introduction
In this article, I'll shift the focus to refactor the **user data management**. Currently, the logic for fetching and saving user data is handled within the component. To create a cleaner, more maintainable architecture, I'll extract this logic into a dedicated service, named `UserService`.
_**A quick note**:_
- _Before we begin, please note that this article builds on concepts and code introduced in previous articles of this series. If you're new here, I highly recommend that you check out those articles first to get up to speed._
- _The starting point for the code I'll be working with in this article can be found in the `15.http-rxjs-operators` branch of the repository https://github.com/cezar-plescan/user-profile-editor/tree/15.http-rxjs-operators._
#### What I'll cover
In this article, I'll guide you through a step-by-step refactoring process to create a dedicated `UserService` and enhance our Angular application architecture:
- **Analyzing the `UserProfileComponent`**: Pinpoint specific areas where data access and manipulation logic can be separated from UI concerns.
- **Creating the `UserService`**: Generate a dedicated service to handle all interactions with the user data API.
- **Handling form data**: Introduce a helper service, `HttpHelperService`, to convert raw form data into the format required for API requests.
- **Eliminating hardcoded URLs**: Replace hardcoded URLs with dynamic configuration using Angular environment files.
- **Managing API paths**: Establish a clear pattern for organizing and maintaining API paths within the `UserService`.
- **Addressing the User ID challenge**: Explore strategies for dynamically determining the user ID without hardcoding it in the service.
By the end of this article, you'll have a deeper understanding of how to structure your Angular applications to achieve better separation of concerns, improved maintainability, and more reusable code.
## Identifying the problem
The [component](https://github.com/cezar-plescan/user-profile-editor/blob/15.http-rxjs-operators/src/app/user-profile/user-profile.component.ts) handles a wide range of tasks, including performing HTTP requests, processing responses, and managing UI interactions. This approach violates the Single Responsibility Principle (SRP), a fundamental principle of software design that states that a class should have only one reason to change. In our case, the component is doing too much!
Let's take a closer look at the HTTP related methods in the component class:
- `loadUserData()` - fetches user data from the server
- `getUserData$()` - defines the observable stream for fetching user data
- `saveUserData()` - saves updated user data to the server
- `saveUserData$()` - defines the observable stream for saving user data
The `getUserData$()` and `saveUserData$()` methods use the Angular `HttpClient` service to interact with the backend API:{% embed https://gist.github.com/cezar-plescan/9bb0257f5a5f4e754a4c5f632be6ae32 %}
These methods not only return observables but also contain hardcoded endpoint URLs. Maintaining these URLs within the component could become a headache if they change in the future. Therefore, these methods are prime candidates for extraction into a separate service class.
But what about `loadUserData()` and `saveUserData()`? They contain even more logic.{% embed https://gist.github.com/cezar-plescan/c19febf1fa47ce2f65686e6ce283566b %}
Should we move them into the service too? The answer is no, because they simply respond to requests, describing how the component UI elements will interact with the received data. These methods are tightly coupled to the component's UI. They handle aspects like: setting UI flags, updating form values, or displaying error messages. These tasks are directly related to the presentation layer and user interaction, which should ideally remain within the component's responsibilities.
I'll extract the reusable, data-centric logic, that is, HTTP requests, into a separate service, while keeping the UI-specific actions within the component. This adheres to the SRP, making the codebase more maintainable and easier to reason about.
In the next section, I'll create the `UserService` class to house the HTTP request logic, leaving the `loadUserData()` and `saveUserData()` methods in the component to manage the UI interactions based on the service's responses.
## Creating the `UserService`
I'll create a service file `user.service.ts` in the `src/app/services` folder using the Angular CLI command `ng generate service user`, then move `getUserData$()` and `saveUserData$()` methods into it.
### Initial content of the service class
Here is the content of the `UserService` class, after simply moving the code from the component:{% embed https://gist.github.com/cezar-plescan/a4cbe484dbfaff72de729973053fec6b %}
There are 2 errors here:
1. `TS2304: Cannot find name 'UserDataResponse'` - this is because the type `UserDataResponse` was defined within the component; I'll address this by creating a shared file for user data types.
2. `TS2339: Property 'form' does not exist on type 'UserService'` - this error arises because the `saveUserData$()` method references the `form` property, which belongs to the component; I'll resolve this by carefully considering where the responsibility for preparing form data should reside.
Let's see how they can be addressed.
### Creating shared user data types
To resolve the first error, I'll create a dedicated file for user related type definitions. I'll name this file `user.type.ts` and place it in the `src/app/shared/types/` folder:{% embed https://gist.github.com/cezar-plescan/fac94f461e3812c7b3e84ad385163de7 %}Then, in the `user.service.ts` file I'll import the `UserDataResponse` type:
```typescript
import { UserDataResponse } from "../shared/types/user.type";
```
This solves the first error. Let's tackle the second one now.
### Delegating form data preparation
The second error is because the `form` property doesn't exist in the new service. This makes sense, as the form is created and managed by the component. But how do we get the form data to the service for the HTTP request?
This situation raises an important design question: **where should the responsibility of processing the form data lie?**
My goal is to adhere to the Single Responsibility Principle (SRP) by grouping related functionalities and extracting them into separate entities, allowing the component to focus on its core responsibility: managing the view, as intended by the Angular team. I'll show you my approach for this situation.
I'll start by analyzing the different players involved in data manipulation and determine where this data processing should occur. I can identify 4 main actors in this process:
- _component_ - it creates and manages the raw form values.
- _raw form values_ - these are the data entered by the user into the form fields.
- _service_ - it's responsible for making the HTTP requests to save the user data.
- _processed form data_ - this is the user data transformed into a `FormData` object, suitable for sending in an HTTP request.
The data flow can be visualized like this: _Component_ ==> _Form Values_ ==> _Processed Form Data_ ==> _Service_ ==> _HTTP Request_.
The raw form values originate within the component and are manipulated by the user through the view. Logically, I can consider these values as an integral part of the component itself.
The processed form data, however, is necessary for the `UserService` to create the HTTP request. Where should the transformation from raw values to `FormData` object take place? Let's consider the options:
1. **within the component**: This would mean the component would be responsible for both managing the view and preparing the data for the request. This would violate the SRP and make the component less focused.
2. **within the service**: This seems more appropriate. The `UserService` would receive the raw form values from the component, process them into a `FormData` object, and then use it for the HTTP request. However, if we ever need another service that requires a similar data transformation, we'd have duplicate code, which isn't ideal.
3. **a separate entity**: This approach is the most flexible and reusable. I could create a helper function or separate service dedicated to generating the `FormData` object. This would allow us to reuse this logic in different parts of our application.
The remaining question is who should invoke the helper function that generates the `FormData` object: the component or the service?
- _the component_: If the component calls the function, it would mean it still has some knowledge about how the data is prepared for the request. This could lead to tight coupling and make the component less reusable.
- _the service_: Having the service invoke the helper function is a better approach. This way, the component can simply provide the raw form values, and the service takes care of the rest, including data transformation and sending the request.
In the spirit of **separation of concerns**, it's more appropriate for the **service** to invoke the helper function. Here's why:
- **data ownership**: the service is responsible for communicating with the backend, and the format of the request data is closely tied to this responsibility.
- **encapsulation**: keeping the data processing logic within the service encapsulates it, preventing the component from being burdened with unnecessary details.
- **testability**: having the service handle data processing makes it easier to write unit tests for both the component and the service independently.
- **flexibility**: this approach allows us to potentially reuse the helper function in other scenarios where we need to prepare the `FormData` for HTTP requests.
By delegating the data processing responsibility to another entity, I create a cleaner architecture where each entity focuses on its core function. The component handles the view and user interactions, while the services take care of data preparation and communication with the backend.
### Implementation of the helper service
Let's see this in practice. I'll create a new service dedicated for HTTP related operations, named `HttpHelperService`, in the `src/app/services` folder, using the Angular CLI: `ng generate service http-helper`. Here is its content:{% embed https://gist.github.com/cezar-plescan/4d1064ae60c9c4a4595db4da198901f4 %}
### Update the `UserService` class
Here is the updated `UserService` class that uses `HttpHelperService`:{% embed https://gist.github.com/cezar-plescan/674af5dd0ebd36a56df9f3b73b6adb5c %}
### Update the component class
There are a couple of changes to be made in the `user-profile.component.ts` file:
- remove the type definitions at the beginning of the file
- inject `UserService`: `private userService = inject(UserService);`
- invoke the two methods of the service
- add `this.form.value` as the argument of the `this.userService.saveUserData$` method
- remove `getUserData$()`, `saveUserData$()`, and `getFormData()` methods if not already done
- import the necessary types
Here is the updated component file:{% embed https://gist.github.com/cezar-plescan/9716a15feb30877faeafe12ca43adaf1 %}

Feel free to explore the repository to see the full implementation details and how the refactored component and services interact.
## Dealing with hardcoded URLs
As I've discussed earlier, the hardcoded URLs for the API endpoints within the `UserService` are less than ideal due to their lack of flexibility, maintainability challenges, and potential security risks. I'll delve deeper into how to solve these issues using **Angular's environment files**.
### Why hardcoded URLs are problematic
- **environment specificity**: The hardcoded URL ties our service to a specific environment (e.g., http://localhost:3000). If we deploy our application to a different server or domain, the URL would be incorrect, and our service would break.
- **configuration changes**: If the base URL for our API changes (e.g., due to server migration or a change in the API version), we'll need to manually update it in every service where it's used, which is error-prone and tedious.
- **scattered configuration**: Having URLs scattered throughout our services makes it harder to manage and update them consistently. It becomes a challenge to keep track of all the places where the URL is used, increasing the risk of errors when changes are needed.
- **code duplication**: If multiple services use the same base URL, we'll likely have duplicate code, violating the DRY (Don't Repeat Yourself) principle.
- **testing challenges**: When testing the service, we'll need to mock the API endpoints. Hardcoded URLs can make it more difficult to replace the real API with a mock during testing.
To tackle these issues, let's take a closer look at the structure of our URLs and discuss who should be responsible for managing them.
### Understanding the URL structure and responsibilities
It's important to understand how our URLs are put together. Let's break down the URL we're using, `http://localhost:3000/users/1`:
- **Base URL**: This is the main address of our API (in this case, `http://localhost:3000`). This can vary depending on where the app is running (our computer, a testing server, or the live server). We shouldn't hardcode this in our service.
- **API Path**: This is the part of the URL that tells the server we want to work with users (`/users`). This should be the service's responsibility.
- **User ID**: This is the specific user we're dealing with (in this case, user number `1`). The user ID might be a _fixed value_ (e.g., when an admin updates a user's data) or represent the _currently logged-in user_. In the latter case, another service, like an `AuthService`, should be responsible for managing it.
Understanding this structure helps us determine who should build the complete URL and where each part should be defined.
### Managing the base URL
The best way to manage the base URL is to use **environment files**. We'll have different files for different environments (development, testing, production). This way, we can easily change the base URL without touching our service code.
#### Creating the environment files
Angular's environment files are a powerful mechanism for managing configuration settings across different environments. They allow us to define variables specific to each environment, keeping our codebase adaptable and maintainable.
Angular comes with a dedicated command for creating these files: `ng generate environments`. This will create two files in the `src/environments` folder: `environment.ts` and `environment.development.ts`. At their core, environment files are simply TypeScript files that export a constant object containing our configuration variables.
Add the following content to the `environment.development.ts` file:{% embed https://gist.github.com/cezar-plescan/f44692e79c952fb4b115189df009c5ee %}
Since we have only one environment right now, I won't use the `environment.ts` file.
To gain a deeper understanding of how environment files work and how to leverage them effectively in your Angular projects, you can explore the following resources:
- [Angular Environment Variables (YouTube)](https://youtu.be/o8wCvlj3IHg) - This video tutorial provides a step-by-step walkthrough of setting up and using environment files in Angular.
- [Angular Environment Variables](https://www.digitalocean.com/community/tutorials/angular-environment-variables) - This DigitalOcean tutorial offers a comprehensive guide on configuring and using environment variables in Angular projects.
- [Angular Basics: Using Environmental Variables to Organize Build Configurations](https://www.telerik.com/blogs/angular-basics-using-environmental-variables-organize-build-configurations) - This Telerik blog post explores the fundamentals of environment variables in Angular and how they can help organize your build configurations.
#### Usage in the UserService
To access the environment variables in our service, we simply need to import the `environment.ts` file:
```typescript
import { environment } from '../../environments/environment';
```
But earlier I've said that this file is not used! Under the hood, Angular replaces the content of this file with `environment.development.ts` file. This happens because `angular.json` file was automatically updated with an additional configuration:
```json
"development": {
"optimization": false,
"extractLicenses": false,
"sourceMap": true,
"fileReplacements": [
{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.development.ts"
}
]
}
```
Now, in the service class, I'll replace the hardcoded URLs with
`${environment.apiBaseUrl}/users/1`
### The `/users` path
The `/users` part of the URL is specific to our API and how it's set up. Since the `UserService` talks to the API, it makes sense for this path to live there. I'll define it as a constant within the service, so it's easy to update if needed.
```typescript
const USERS_API_PATH = 'users';
`${environment.apiBaseUrl}/${USERS_API_PATH}/1`
```
### Handling the User ID
There are primarily two main approaches to providing the user ID to the `UserService`:
1. pass as argument: the component, considering it's aware of the current user context, explicitly passes the user ID as an argument when calling service methods like `getUserData$` or `saveUserData$`.
2. service retrieval: the `UserService` itself fetches the user ID from another source; this source could be route parameters, an authentication service, or even a state management system like NgRx.
It's important to note that, regardless of the method, fetching the user ID isn't the `UserService`'s primary responsibility.
The best method depends on how the application is structured and how complex it is. In this tutorial, to keep things simple, I'll leave the user ID hardcoded for now, as there's no real context to determine which option is the most suitable. However, in a real-world project, you'd choose the option that best fits your specific needs and keeps your code clean and easy to maintain.
### See the code in action
To see all of these changes in action and get a better understanding of how the pieces fit together, check out this specific revision in the repository https://github.com/cezar-plescan/user-profile-editor/tree/308208159bd28d6ff3a5f4959ba6d867c1ae632a.
## Conclusion
In this article, we successfully refactored our `UserProfileComponent`, tackling the challenge of tightly coupled responsibilities. By extracting the data access and form data preparation logic into dedicated services – `UserService` and `HttpHelperService` – we've achieved a cleaner and more maintainable codebase.
Here's what we've accomplished:
- **Improved separation of concerns**: Our `UserProfileComponent` is now focused on its core responsibility: managing the user interface and interactions.
- **Enhanced reusability**: The extracted services can be easily reused in other parts of our application, saving us time and effort.
- **Better code organization**: Our project structure is more modular and easier to navigate.
This refactoring effort not only simplifies our current code but also paves the way for future enhancements. With a more streamlined component and reusable services, we can easily add new features or modify existing ones without worrying about unintended side effects.
Feel free to explore and experiment with the code from this article, available in the `16.user-service` branch of the [GitHub repository](https://github.com/cezar-plescan/user-profile-editor/tree/16.user-service).

Why use Django in a world where everything is Javascript? Is it really worth learning a Python Framework in an ecosystem that insists on Frameworks written in Javascript? Well, I think so, and here are some of the reasons why you should use Django. And, in order not to lose objectivity, I will talk about the advantages as well as the disadvantages; you know that no solution is perfect.
## The advantages of Django
### Its ORM is simple and wonderful
Django’s ORM abstracts away the need to write SQL queries to create tables and query data. It is quite intuitive to use and has almost all the most common queries included in its code. From filtering, partitioning, joins and even [advanced Postgres lookups](https://coffeebytes.dev/en/trigrams-and-advanced-searches-with-django-and-postgres/) functions and migration handling.
To create a table in the database just create a class that inherits from _models.Model_ and Django will do all the heavy lifting.
``` python
class Review(models.Model):
title = models.CharField(max_length=25)
comment = models.TextField()
name = models.CharField(max_length=20)
created = models.DateTimeField(auto_now_add=True)
modified = models.DateTimeField(auto_now=True)
user = models.ForeignKey(
get_user_model(), related_name="reviews", null=True, on_delete=models.SET_NULL)
```
The following model is equivalent to the following SQL statement:
``` sql
BEGIN;
--
-- Create model Review
--
CREATE TABLE "reviews_review" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "title" varchar(25) NOT NULL, "comment" text NOT NULL, "name" varchar(20) NOT NULL, "created" datetime NOT NULL, "modified" datetime NOT NULL, "user_id" integer NULL REFERENCES "auth_user" ("id") DEFERRABLE INITIALLY DEFERRED);
CREATE INDEX "reviews_review_user_id_875caff2" ON "reviews_review" ("user_id");
COMMIT;
```
In addition to the above, its ORM supports multiple databases, so switching database engines is quite simple and after a few changes you can migrate seamlessly from Postgres to MySQL or vice versa, just by changing a couple of lines in the configuration. Saving you from having to write SQL by hand, as you would do in [migrations from another language, such as go](https://coffeebytes.dev/en/go-migration-tutorial-with-migrate/).
``` python
# settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'OPTIONS': {
'read_default_file': '/path/to/my.cnf',
},
}
}
```
Its only disadvantage is its speed, as it falls short of alternatives such as sqlAlchemy, or [tortoise-orm](https://coffeebytes.dev/en/python-tortoise-orm-integration-with-fastapi/).
### Administrator panel included
Django has the [django admin panel](https://coffeebytes.dev/en/the-django-admin-panel-and-its-customization/), an administration panel that is installed by default. This admin implements a CRUD to the database in a simple way. And, in addition, it has a solid permissions system to restrict access to the data as you want.
[](images/Django-panel-admin.png)
### Offers security against the most common attacks
Django includes certain utilities, which are responsible for mitigating most attacks such as XSS, XSRF, SQL injections, Clickjacking and others. Most of them are already available and you just need to add the corresponding middleware or template tag.
``` html
<form method="post">{% csrf_token %}
```
### User management included
Most applications require a user management system, you know, register them, activate them, log them in, password recovery, well, Django already includes all of the above by default, even decorators to restrict views for authenticated users.
#### Authentication tested, including with JWT.
This framework has a proven authentication system based on sessions that are identified by a cookie. The authentication system has already been tested numerous times by some of the most trafficked websites out there, such as Instagram or the NASA website. Pinterest started with Django but moved to node.
You can use cookie authentication, session authentication or there are packages that allow you to use it with JWT. By the way, I have a post where I explain how to [authenticate a user using JSON Web token JWT in Django Rest Framework](https://coffeebytes.dev/en/django-rest-framework-and-jwt-to-authenticate-users/). I also wrote another one explaining why [some consider this is not a good idea](http://cryto.net/~joepie91/blog/2016/06/13/stop-using-jwt-for-sessions/).
#### Django’s Permit system
Django has a robust [permissions and groups system](https://coffeebytes.dev/en/how-do-permissions-and-permissions-groups-work-in-django/) that binds your users to models in the database that you can start using with just a few lines of code.
### Multiple packages
Django has a lot of packages to solve most common problems, and they are community-monitored and community-improved packages, which guarantees impressive quality.
Just to name a few:
- [Django-haystack](https://coffeebytes.dev/en/searches-with-solr-with-django-haystack/)(For searches complex)
- Django-watson (Searches)
- DRF (REST)
- Graphene (Graphql)
- Django-rest-auth (Authentication)
- Django-allauth (Authentication)
- Django-filter (Search)
- Django-storage (AWS storage)
- Django-braces (Common functions)
Among all of them I would like to highlight **DRF (Django Rest Framework) which makes [creating a REST API](https://coffeebytes.dev/en/basic-characteristics-of-an-api-rest-api/), handling permissions and [throttling](https://coffeebytes.dev/en/throttling-on-nginx/), a simple task**, compared to creating everything from scratch.
Another package to highlight that allows you to work with websockets, to create an [application that communicates with the server in real time, through events, is django-channels](https://coffeebytes.dev/en/django-channels-consumers-environments-and-events/).
### Takes you from an idea to a working prototype quickly.
I consider this the main reason to use Django. **Django gets you from an idea to an MVP fast and without reinventing the wheel**. Which is a huge competitive advantage over other frameworks, especially when money and customers are involved.
With Django you would have a working prototype faster than with any other “less opinionated” framework or one that requires you to program everything from scratch.
### It is a proven solution
There are many new frameworks every day. Most of them are just a fad and fall into disuse over the years, leaving projects without support. Django is a framework that has been around for a very long time, that has gone through numerous tests that have made it robust and reliable, and that is not going to disappear overnight leaving you with an unsupported project.
Consider that Django was once the choice of sites as big as Instagram or Pinterest.
### Django support for Machine Learning libraries
Python is great when it comes to Machine Learning, cool libraries like Pytorch, ScikitLearn, Numpy and Keras are widely used worldwide. Since Django is written in Python, you will be able to integrate these libraries natively into your Django projects, without the need to create a new service.
## The disadvantages of Django
Not everything is magic with Django, there are some things that can be considered a disadvantage and that I would change without hesitation.
### It is a monolith
Django is an old Framework, with everything you need to develop a web application, an ORM, a templating system, middleware and many other pieces that are there and are required for the framework to work, whether you need them or not. However, Django can be modularized to generate API responses in JSON (or other format) instead of HTML, ignoring the rest of the framework machinery.
The very stability of Django has made it look somewhat slow in a world of rapidly evolving JavaScript frameworks.
**Update** : Regarding the template system, if you combine it with libraries like htmx or turbolinks you will have the best of both worlds: interactivity on the frontend with HTML generation on the backend.
### It is slow and handles requests one at a time.
Python is an interpreted language that was made to be beautiful and simple, not necessarily performant. In my comparison of [python vs go](https://coffeebytes.dev/en/python-vs-go-go-which-is-the-best-programming-language/) I compare the performance of both, just to give you an idea.
In addition to the above, Django does not shine for its speed at the time of execution. In the race to be a fast framework, it is below more modern technologies such as Flask or FastAPI.
Go to [my tutorial on FastAPI](https://coffeebytes.dev/en/fastapi-tutorial-the-best-python-framework/) if you want to see how slow Django is compared to other frameworks.
### Djang’s ORM is not asynchronous nor the fastest.
Django is working to make its ORM asynchronous, but it’s not there yet. Other alternatives such as tortoise-orm, sql-alchemy, pony-orm are ahead in this aspect.
### Moderate learning curve
Django follows the philosophy of batteries included. Which is good, because it’s code you save writing, but also bad, because it’s code you need to learn to use: the ORM with models and queries, the middleware, the views, DRF (for the APIs) or the template system, the urls handler, string translation, the i18n package, etc. Learning all of the above takes more time than it would take you to learn other more minimalist frameworks; such as Flask or Express.
## TLDR advantages and disadvantages of Django
From my point of view the advantages outweigh the disadvantages, so I consider it a very attractive option to develop a complex website when you have little time or need to find developers fast.
Still not convinced? Remember that Instagram is the largest Django backend website out there and despite they’ve been modifying their system slowly, it was thanks to Django’s rapid prototyping that allowed them to became the monster app that they’re now.
In the end, as always, this is my point of view and everyone has their own. I hope this post has shown you something you would not have considered about Django before reading it. | zeedu_dev |

The entrepreneurial drive encompasses... | 0 | 2024-06-20T09:55:45 | https://dev.to/spanking_solutions_0af849/5-common-mistakes-new-businesses-make-1kda | 5 Common Mistakes New Businesses Make (And How to Avoid Them).
The entrepreneurial drive encompasses many individuals, and the desire to set up one’s own business can generate much interest. But the road to success is rarely easy. Many new projects face initial setbacks, often due to preventable errors. By identifying this pitfall, corrective action can be initiated early to increase the chances of continued success.
Here are 5 common mistakes new businesses make, and solutions to avoid them:
Mistake #1: Lack of planning and unrealistic expectations:
Rephrase Numerous emerging enterprises neglect the crucial process of crafting an all-encompassing business blueprint. This dossier acts as a guide, delineating your business goals, tactics, audience segments, financial benchmarks, and additional details. Without a strategy, it is simple to veer off course in the day-to-day operations and lose focus on the broader strategic outlook. Furthermore, novice business owners frequently harbor impractical anticipations regarding the rate of their business growth. Establishing a thriving business necessitates patience, commitment, and a readiness to pivot as necessary.
How to avoid:
Craft a comprehensive business plan by dedicating time to its development. Your plan need not be an extensive 100-page manuscript; a concise version outlining your goals, tactics, and a transparent financial projection will serve the purpose effectively.
Perform in-depth market analysis: Thoroughly examine your specific market segment to gain insights into their requirements, inclinations, and purchasing behaviors. This approach will ensure that your product or service aligns effectively with their expectations. Establish achievable objectives: Develop attainable and quantifiable objectives for your enterprise. To monitor advancement and maintain inspiration, divide overarching goals into manageable and actionable increments.

1,894,758 | GitLab Shared Responsibility Model: A Guide to Collaborative Security | GitLab is a popular DevSecOps and collaborative software development platform that enables businesses... | 0 | 2024-06-20T11:59:44 | https://gitprotect.io/blog/gitlab-shared-responsibility-model-a-guide-to-collaborative-security/ | gitlab, devops, developers, coding | GitLab is a popular DevSecOps and collaborative software development platform that enables businesses to automate software delivery, boost productivity, and secure end-to-end software supply chains. However, not everyone knows that like most SaaS service providers, GitLab operates according to the so-called Shared Responsibility Model (or Limited Liability Model).
This model recognizes the responsibilities of each party at the very moment when a customer creates an account on GitLab and starts using this service. But, do all the users know what responsibilities they have at the beginning? Not sure.
Thus, let’s try to understand what is a GitLab Shared Responsibility Model and what obligations each of the parties has to follow in order to achieve the code repository security.
## What is the Shared Responsibility Model?
To make a long story short, the Shared Responsibility Model is a framework for cloud security that defines the security duties for both SaaS providers and their users. It defines that a provider takes care of the infrastructure, and the entire service while a customer should think about his own data and related metadata.
Though GitLab provides a rather full package of tools, including backup and retention schemes, it is always a good idea to know what is really included in the service and what you, as a customer, should think of.
## GitLab’s Shared Responsibility Model in action
Being transparent with its documentation, [GitLab states](https://about.gitlab.com/security/faq/#cloud-security): _“As part of GitLab Inc’s contracting process, GitLab provides all terms and conditions with our customers to ensure all parties understand the shared responsibility model.”_ So, let’s dive deeper and look closely at the [GitLab Subscription Agreement](https://handbook.gitlab.com/handbook/legal/subscription-agreement/#2-scope-of-agreement-additional-terms) where the Git hosting service states all the responsibilities of both parties – its own and its users.
## What is GitLab responsible for?
If we peer into the GitLab Subscription Agreement mentioned above we will notice that _“GitLab shall be responsible for establishing and maintaining a commercially reasonable information security program that is designed to”_:
- guarantee the confidentiality and security of GitLab user’s content;
- guard against potential threats to the security of the user’s content;
- prevent unauthorized access or unauthorized use of the user’s content;
- make sure that GitLab’s subcontractors, if there are any, abide by the aforementioned requirements.
It sounds security-proof, doesn’t it? Moreover, if we look at the [GitLab Trust Center](https://about.gitlab.com/security/), we can see that GitLab has a proven compliance and assurance credentials path. The service provider has passed numerous security certifications, including SOC 2 Type 1 and 2, SOC 3, ISO 27001, ISO 27017, GDPR, and others. Thus, it has high-security standards to protect its data: “In no case shall the safeguards of GitLab’s information security be less stringent than the information security safeguards used by GitLab to protect its own commercially sensitive data” ([Subscription Agreement: Security / Data Protection](https://handbook.gitlab.com/handbook/legal/subscription-agreement/#14-security--data-protection)).
So, GitLab is responsible for access to the platform and the infrastructure, backup which is run on the same Linux server as GitLab, configurations and maintenance modes, upgrades (here it’s worth mentioning that GitLab isn’t available when the update is in progress for single node installations), and infrastructure-side Disaster Recovery.
And what about the user’s data? Here is what is stated in the same document:
So, are the users responsible for their data? Yup… Let’s continue talking about it…
## A Customer’s Responsibility: Deep Analysis
While GitLab takes care of the entire system, a customer is responsible for his authorization credentials and all the data in his code repository. It can include Repositories, Wiki, Issues, Issue comments, Deployment keys, Pull requests, Pull request comments, Webhooks, Labels, Milestones, Pipelines/Actions, Tag, LFS, Releases, Collaborants, Commits, Branches, Variables, GitLab Groups. So as not to sound unfounded, take a look at what is stated in [GitLab documentation](https://handbook.gitlab.com/handbook/legal/subscription-agreement/#5-restrictions-and-responsibilities):
Once again, users are responsible for the security of their accounts, _“passwords, and files”_. It means that if something, for example, accidental or intentional deletion of the data takes place, the customer’s problem is figuring out how to restore it if possible.
Don’t forget it’s a myth that if your account data is deleted or corrupted GitLab can recover it. Read our blog post from the [DevSecOps MythBuster series](https://gitprotect.io/blog/devsecops-mythbuster-nothing-fails-in-the-cloud-saas/) where we have already debunked this myth: [“GitHub / Atlassian / GitLab handles backup and restore” – busted!](https://gitprotect.io/blog/github-atlassian-gitlab-handles-backup-and-restore-busted/)
## Let’s look further into the Shared Responsibility Model
After figuring out which security obligations both parties have, we should definitely speak about cooperation… As the GitLab Shared Responsibility Model, like any other of its type, emphasizes the collaboration between the platform provider and its users. Here are the key aspects that are worth mentioning as well:
## Education and training
There are thousands of resources and documentation that GitLab prepares to educate its users about best security practices. Thus, in turn, users should always try their best to stay in the loop – read documentation, blog posts, and undergo security training to boost their security skills.
## Feedback and reporting
As it has already been mentioned GitLab encourages its users to provide timely feedback about any issues they face. By promptly reporting vulnerabilities or any suspicious activity, users not only play an active role in the security ecosystem but also help the provider respond to the issues faster.
## Continuous improvement
As any other SaaS provider, GitLab regularly updates its product. So, it’s critically important for the users to follow these updates as they are usually aimed at improving user experience and security.
## What can go wrong?
Human mistakes, [ransomware attacks](https://gitprotect.io/blog/ransomware-attacks-on-github-bitbucket-and-gitlab-what-you-should-know/) (which are on the rise now!), service provider’s outages, or your own infrastructure outages – all of that can severely impact your business continuity and, what’s worse, lead to data loss. Why not track the history of incidents and see on Use Cases why your GitLab data needs proper protection?
## GitLab’s backup failure
Let’s just remember the year 2017 when the worst incident in GitLab’s history took place. Due to the accidental deletion of data, GitLab suffered an outage and needed urgent database maintenance. The service provider’s backup failed to restore, and, consequently, users who used the SaaS solution suffered data loss:
> “The company has reached out to confirm that the outage only affects GitLab.com – meaning that customers using its platform on-premise are not affected.”
[TechCrunch](https://techcrunch.com/2017/02/01/gitlab-suffers-major-backup-failure-after-data-deletion-incident/?guccounter=1&guce_referrer=aHR0cHM6Ly93d3cuZ29vZ2xlLmNvbS8&guce_referrer_sig=AQAAANGfN4XNQ6_5YvTcG5OVoXEmmBC-Ja4bpca4UHZlS6jZZH7cTtfMQSobsQq0QdFh0Wmlb2jl_A9z8cwR8njl_ZoeTT4p1RzYIz6hd7dixlqMoiFYPIYQI9jhgw01jnr_Sqmileq9FdZb6383juRN_nFS5pD1XrLPkTEU_g7oIdKJ)
## Proxyjacking and cryptojacking malware attack on GitLab
In August 2023 researchers from Sysdig were alerted to a persistent campaign of attacks targeting vulnerable GitLab servers that resulted in the deployment of proxyjacking and cryptojacking malware, leveraging the platform’s resources for the attacker’s own gains.
Though, GitLab effectively addressed and patched the mentioned vulnerabilities labeled as 13.8.8, 13.9.6, and 13.10.3 in April 2021, _“individuals who failed to apply these patches have now become targets for the LABRAT threat.”_ – states [Cybersecurity Insiders](https://www.cybersecurity-insiders.com/gitlab-vulnerability-leads-to-proxyjacking-malware-campaign/).
## Is there anything DevSecOps teams should be aware of?
If a company is really conscious about its repository data, it will think about backup – it’s nice to have the possibility to roll your data back in case of a failure. They can make up their own backup options, such as [backup scripts](https://gitprotect.io/blog/how-to-write-a-gitlab-backup-script-and-why-not-to-do-it/), clones, and snapshots, or use any other [GitLab backup option](https://xopero.com/blog/en/the-best-gitlab-backup-options-and-tools-to-ensure-gitlab-data-resilience/). But at the same time, they should keep in mind that they will need to do it manually, which is time-consuming and takes a lot of resources.
Well, it may seem easy and cheap but in the long-term perspective, it will be tiring and cost-ineffective. Why? In short – in a situation like that, somebody from the company will need to switch from his usual duties to provide backup copies. He will need to make those backup scripts, snapshots, and clones, keep his hand on the pulse to delete the old ones because they can waste a lot of storage space, and, when it is needed, write the script to restore the data. So, your developer will be always distracted from his core duties, which will affect his productivity.
## Is there any other option to back up the data?
The solution is on the surface! A lot of SaaS providers don’t exclude the possibility of turning to a third-party backup and recovery solutions. In this case, companies can rely on professionals who will help them reduce their responsibilities and compliance. For example, [GitLab backup](https://gitprotect.io/gitlab.html) by GitProtect.
If a customer decides to share his responsibilities with a third-party backup provider, he can get **automated backups and data protection** using the most popular and reliable backup rule, **the 3-2-1 strategy**. Under this rule, you can have three copies of your data in two different locations including one outside the company. This sounds great because GitLab gives the possibility to store all the data only on the same Linux server as GitLab. Also, it is possible to set up more advanced retention schemes, like FIFO, GFS, or Forever Incremental, which will surely help when you need to restore your data, whether it is point-in-time or [Disaster Recovery](https://gitprotect.io/blog/gitlab-restore-and-disaster-recovery-how-to-eliminate-data-loss/).
We have mentioned that GitLab, like any other SaaS service, provides its customers with a retention option, but it is always limited. Some companies may need to keep their data for long periods due to their legal regulations or archive purposes. Thus, **they may need long-term retention options**. When a third-party backup service steps in, it is possible to get unlimited retention for backup copies. It means that all your information, even the oldest one, can be kept in a safe place and easily restored at any time you need.
Another point we need to pay attention to is updating. For single-node installations, GitLab isn’t available when the update is proceeding. In this case, a third-party solution can relieve the stress again. In situations like that you shouldn’t stop your work and wait, **you can restore your repository using cross-over recovery to another platform**, like GitHub or Bitbucket, and continue your work.
## Conclusion
Once you decide to use a service, it is always good to know the legal side and the responsibilities of the parties. Because, when you know what to do, what responsibilities you have, and what to expect, you won’t be taken aback.
The way the so-called Shared Responsibility Model defines the roles is that it is always a customer, who should protect their data because he is a data owner. The SaaS provider, in our case, GitLab is just a data processor, who can process the data when and if the data owner permits. And if the customer – data owner – wants, he can add a data guard (a third-party backup and recovery solution) which will guarantee data accessibility and sustainability.

1,894,757 | 🧠 The Ultimate JavaScript Head-Scratcher: typeof null and Other Peculiarities! 🤯 | Hey Devs! Buckle up because today we’re diving into the wacky world of JavaScript quirks that will... | 0 | 2024-06-20T11:59:31 | https://dev.to/ankit_kumar_41670acf33cf4/the-ultimate-javascript-head-scratcher-typeof-null-and-other-peculiarities-4cjp | javascript, beginners, webdev, ai | Hey Devs!
Buckle up because today we’re diving into the wacky world of JavaScript quirks that will make you question your sanity, your code, and possibly your life choices. Let's decode some of the most bizarre, brain-twisting aspects of JavaScript that only the bravest dare to confront. 🚀
-
typeof null is object? Whaaat? 🤷♂️
```
console.log(typeof null); // 'object'
```
Why? Because of reasons. Well, it’s a bug in JavaScript that's been around since day one, and fixing it now would break the web. 🤦
-
The Mystery of NaN (Not-a-Number)
```
console.log(NaN === NaN); // false
```
That’s right. In the JavaScript universe, even NaN doesn’t equal NaN. It's like trying to compare apples and oranges, but both are on fire. 🔥🍏🔥🍊
-
The Schrodinger’s Cat of Arrays 🐱📦
```
const arr = [1, 2, 3];
arr.length = 0;
console.log(arr[0]); // undefined
```
You just made the whole array disappear like a magic trick. Poof! 🎩✨
-
The Incredible Mutating const
```
const obj = { a: 1 };
obj.a = 2;
console.log(obj.a); // 2
```
Surprise! const doesn’t make the object immutable. It just means you can’t reassign obj to something else, but you can still mutate its contents. Sneaky, right? 🕵️♀️
-
The Case of the Floating Decimal
```
console.log(0.1 + 0.2 === 0.3); // false
```
Just when you thought you could trust math, JavaScript throws in some floating-point shenanigans to keep you on your toes. 🤡
-
The Time-Traveling Date
```
const date = new Date('2024-06-20');
date.setDate(date.getDate() - 1);
console.log(date.toString()); // Date in the previous month or year!
```
Dates are like time machines in JavaScript. Change one thing, and who knows where you'll end up? 🕰️🔮
-
The Mystery of Array vs. Object
```
console.log([] instanceof Object); // true
```
Arrays are just specialized objects in JavaScript. It's like finding out your cat is actually a small, furry object that meows. 🐈➡️📦
-
The Phantom undefined
```
let phantom;
console.log(phantom); // undefined
console.log(typeof phantom); // 'undefined'
```
Undefined variables are a rite of passage in JavaScript. Embrace the void! 🌌
-
The Inescapable Infinity
```
console.log(1 / 0); // Infinity
```
Divide by zero, and JavaScript just gives up and declares infinity. Simple as that. ♾️
-
The Quantum Leap of == and ===
```
console.log(0 == '0'); // true
console.log(0 === '0'); // false
```
== and === are like parallel universes in JavaScript. One loves type coercion, and the other doesn’t even know what that means. 🌌🔗

1,894,753 | Understanding Observers in Ruby on Rails | As your Ruby on Rails application grows, maintaining clean and manageable code becomes increasingly... | 0 | 2024-06-20T11:56:23 | https://dev.to/afaq_shahid/understanding-observers-in-ruby-on-rails-88c | webdev, ruby, rails, refactorit | As your Ruby on Rails application grows, maintaining clean and manageable code becomes increasingly important. One of the powerful yet often underutilized features in Rails is the Observer pattern. Observers allow you to keep your models lean by extracting responsibilities that don't necessarily belong in the model itself. In this article, we'll explore what observers are, when to use them, and how to implement them in your Rails application.
### What are Observers?
Observers in Rails provide a way to respond to lifecycle callbacks outside of your models. They allow you to encapsulate the callback logic in a separate class, promoting cleaner and more modular code. Observers listen for changes to an object and respond to those changes without the object needing to explicitly notify the observer.
### When to Use Observers
Observers are ideal for situations where you want to decouple the callback logic from your models. Here are a few common use cases:
1. **Logging and Analytics:** Track changes or actions performed on a model without cluttering the model code.
2. **Notifications:** Send emails, Slack messages, or other notifications when certain model events occur.
3. **Asynchronous Jobs:** Enqueue background jobs in response to model changes.
4. **Complex Business Logic:** Implement business rules that should be applied after certain model changes.
### Implementing Observers in Rails
Rails observers are not included in Rails by default anymore, starting from Rails 4. However, you can still use them by including the `rails-observers` gem in your Gemfile:
```ruby
gem 'rails-observers'
```
After adding the gem, run `bundle install` to install it.
### Creating an Observer
Let’s walk through an example of creating an observer. Imagine you have a `User` model and you want to send a welcome email whenever a new user is created.
1. **Generate the Observer:**
First, generate the observer file:
```bash
rails generate observer User
```
This will create a file `app/models/user_observer.rb`.
2. **Define the Observer:**
Open the generated `user_observer.rb` file and define the callback methods:
```ruby
class UserObserver < ActiveRecord::Observer
def after_create(user)
UserMailer.welcome_email(user).deliver_later
end
end
```
Here, `after_create` is a callback method that will be triggered after a new user is created. The `UserMailer.welcome_email(user).deliver_later` line enqueues the welcome email to be sent asynchronously.
3. **Register the Observer:**
To make Rails aware of the observer, you need to register it. Open `config/application.rb` and add the following line inside the `class Application < Rails::Application` block:
```ruby
config.active_record.observers = :user_observer
```
4. **Create the Mailer:**
If you haven't already, generate the mailer:
```bash
rails generate mailer UserMailer
```
Define the `welcome_email` method in `app/mailers/user_mailer.rb`:
```ruby
class UserMailer < ApplicationMailer
def welcome_email(user)
@user = user
mail(to: @user.email, subject: 'Welcome to My Awesome Site')
end
end
```
Also, create a view template for the email in `app/views/user_mailer/welcome_email.html.erb`.
### Benefits of Using Observers
- **Separation of Concerns:** By moving callback logic to observers, your models remain focused on their primary responsibility: data persistence and validation.
- **Reusability:** Observers can be reused across different models, promoting DRY (Don't Repeat Yourself) principles.
- **Maintainability:** With a clean separation of callback logic, your codebase becomes easier to maintain and understand.
### Conclusion
Observers are a powerful tool in the Rails ecosystem for maintaining clean and modular code. By decoupling callback logic from your models, you can achieve a more maintainable and scalable codebase. While Rails no longer includes observers by default, the `rails-observers` gem makes it easy to integrate this pattern into your application. Use observers to handle logging, notifications, complex business logic, and more, ensuring your models remain lean and focused on their primary responsibilities.
Happy coding!

1,894,748 | There’s a magic to Game Mechanics In Video Games | Everyone has played before. Everyone has played video games. Our childhoold depended on them. But... | 0 | 2024-06-20T11:53:13 | https://dev.to/zoltan_fehervari_52b16d1d/theres-a-magic-to-game-mechanics-in-video-games-32mn | gamemechanics, gamedev, gamephysics, gaming | Everyone has played before. Everyone has played video games. Our childhoold depended on them.
**But now, as adults, let’s look at them from another angle:**
Video games create immersive experiences by seamlessly integrating storytelling, visual artistry, sound design, and gameplay mechanics. These serve as the core elements, crafted by developers to construct the interactive aspects of gameplay. Game mechanics encompass a spectrum of elements, from basic actions such as jumping and shooting to complex systems including skill trees and resource management. They act as the foundational rules and guidelines that direct player interactions and significantly impact the game’s progression and outcome.
## Game Mechanics Definition
Game mechanics refer to the rules, systems, and elements that make up the structure of a video game. These mechanics dictate how the game functions, what actions players can take, and how the game responds to those actions. It’s important to note that game mechanics are not the same as gameplay, which refers to the overall experience of playing a video game.
Instead, they are the building blocks of gameplay, providing a framework for player interaction with the game world. A game mechanic can be something as simple as jumping or shooting, or something more complex, like a skill tree or crafting system. Regardless of its complexity, a game mechanic is designed to provide a specific function or purpose within the game.
## The Importance Of Game Mechanics
Game mechanics are crucial components within video games that serve to engage players, immerse them within the game world, and ultimately enhance the overall player experience. These involve the rules, systems, and tools used to create and balance a game. They determine how players interact with the game environment and determine how successful they are within it.
The role of game mechanics in video games is hard to underestimate. Successful mechanics are designed to provide a sense of balance, challenge, and reward for players. It is not just about providing entertainment but providing a holistic experience that keeps players engaged for long periods.
## Game Mechanics: Key Categories
**Action Mechanics** Action mechanics in video games focus on creating a gameplay experience that feels responsive and dynamic. These mechanics include jumping, running, sliding, climbing, and combat. Examples: Super Mario Bros., Assassin’s Creed, Uncharted, Sonic the Hedgehog, Batman: Arkham series.
**Strategy Mechanics** Strategy mechanics require players to make decisions, plan moves, and develop tactics to accomplish goals within the game. Examples: Age of Empires Series, Total War Series, Civilization Series, Command & Conquer Series, XCOM Series.
**Exploration Mechanics** Exploration mechanics provide players with the thrill of discovering unknown territories, unearthing secrets, and engaging with the in-game environment. Examples: The Legend of Zelda: Breath of the Wild, Skyrim, Red Dead Redemption 2, No Man’s Sky, Assassin’s Creed Odyssey.
**Resource Management** Resource management determines how players allocate and optimize in-game resources. Examples: Civilization Series, Stardew Valley, Minecraft, StarCraft Series, Factorio.
**Role-Playing Mechanics** Role-playing mechanics allow players to immerse themselves in a character’s story or progression through dialogue choices, skill points, and customization options. Examples: The Fallout series, The Witcher franchise, The Elder Scrolls games.
**Turns and Action Points** Turn-based mechanics involve players taking turns to make decisions or actions, while action points limit the number of actions a player can execute within a particular time frame. Examples: Baldur’s Gate 3, Final Fantasy Tactics, Divinity: Original Sin 2, Fallout Series (Classic titles), Gears Tactics.
**Game Modes** Game modes dictate how players experience the game, from single-player to multiplayer, cooperative to competitive.
## Other Important Game Mechanics
1. Quick-time events (QTEs)
2. Artificial intelligence (AI) for non-player characters (NPCs)
3. Physics engines
4. Weather systems
5. Day-night cycles
6. Player decision and choice systems
7. Environmental interaction
8. Real-time and dynamic world changes
9. Scripted events
10. Player character customization and progression
## Game Mechanics And Immersion
Game mechanics play a key role in creating immersion, where players feel deeply connected to the game’s universe. Sophisticated physics engines and advanced AI behaviors can lead to realistic encounters, while poor mechanics can break immersion. Well-implemented mechanics that align with the game’s themes can captivate players, while lackluster ones can hinder the immersive experience.
## Evolving Game Mechanics: Shifts Based On Player Preferences
Game mechanics have evolved to suit new genres and game formats. One notable shift is their adaptation to changing player preferences. Technological advancements have enabled more lifelike movement and interactions, leading to the introduction of new mechanics, such as parkour and grappling in action games.
## Harmonization: Balancing Game Mechanics
Balancing [game mechanics](https://bluebirdinternational.com/game-mechanics/) involves harmonizing different mechanics to provide a challenging, fair, and enjoyable player experience. Effective balancing adjusts difficulty in line with player progression and offers diverse options and pathways for game progression. By considering player feedback and constantly refining mechanics, designers can create an immersive and captivating gaming experience. | zoltan_fehervari_52b16d1d |

1,894,746 | From Side Hustle to Main Income: Transitioning Financially | Do you have a small job on the side? A little something that makes you cash? What if you turned that... | 0 | 2024-06-20T11:51:29 | https://dev.to/kevin_c864b029545c2e7873d/from-side-hustle-to-main-income-transitioning-financially-4gbc | Do you have a small job on the side? A little something that makes you cash? What if you turned that side job into your main pay? It can be done, but you must plan carefully first.
Turning your side work into your real job is very exciting. You get to be your boss! You can focus all your time on something you love doing, but it also comes with challenges. Your income may change from week to week at first.
You must plan for slow times, too. There are also new tax and legal things to learn. Despite the work involved, making this change can be so rewarding!
## Evaluate the Viability of Your Side Hustle
You have a small job on the side. It helps you make money, but can you do it as a big job? First, you need a steady flow of money. Your side job must make you cash each month. The money should come in most weeks. This proves people want what you sell.
**The Market Has Room to Grow**
- There is still high demand for your product or service
- Not too many others are selling the same thing
- The market is growing and will keep growing
You can find data to show these things. Market research reports help in looking at trends also helps prove there is room to grow.
**You Make Good Profits After Paying Costs**
Look at all the costs to run your side job. Think about materials, labour, rent, marketing, and other expenses. Subtract costs from your income to get profits. Your profits should be healthy and worth the work.
## Build Up Savings
Living costs won't stop when you make the switch. You need cash saved up to cover bills. You should aim to save at least six months of living costs.
**Income Can Change at First, So Plan Ahead**
- Your pay may dip when you first make the switch
- Some months may make less money than others
- You may have a slow period before things pick up
Don't quit without cash saved up! This cushion helps when money is tight. You can dip into savings stress-free.
Go through your bills and cut whatever you can, or cancel streaming services, gym memberships, etc. Make sacrifices now to save cash, as less spending means less money needed each month.
If needing cash to help with the transition, a loan could help. For those with poor credit, **[5000 loans for bad credit](https://www.advanceloanday.co.uk/5000-loans.html)** could work. These loans don't require a high credit score. The lender looks at income and ability to repay instead. This cash could help launch the new business smoothly. Just have a solid plan to repay the loan on time. The funds give a needed boost while preserving savings.
## Plan for Business Growth
Having goals motivates you and guides your actions but makes them realistic. Aiming too high sets you up for frustration. Set goals like:
- Earn X amount more in profits this year
- Get X new clients or customers each month
- Launch X new products or services within a year
## Invest Wisely in Marketing
Marketing is key to reaching more people and making bigger profits. But it costs money, so spend carefully on strategies proven to work:
- Create a professional website to promote your business
- Use social media and online ads to reach your target market
- Attend local events or join networking groups in your industry
## Diversify Income
Don't rely on just one product, service, or income source. If it dries up, you're in trouble. Find ways to diversify like:
Offer complementary products or services to existing customers
Explore other revenue streams related to your expertise
Consider passive income ideas like ebooks, online courses, etc.
**You May Need a Large Loan for Business Investments**
Funding growth can require a large sum upfront. If you lack savings, loans could provide that capital boost. For poor credit, **[no guarantor loans from a direct lender](https://www.advanceloanday.co.uk/bad-credit-loans/no-guarantor.html)** may work well. These are based on affordability, not credit score. The cash enables investing in new products, marketing, etc. Just ensure budgeting to afford the fixed monthly repayments.
## Handle Tax and Legal Tasks
Being self-employed means new obligations around taxes and regulations. Get these right to avoid penalties or issues down the road:
- Register as self-employed and understand estimated tax payments due
- If hiring staff, register as an employer with HMRC
- Decide if forming a limited company is worthwhile for liability protection
- Maintain flawless records of all income, expenses, invoices, etc.
## Gradually Transition
You still need steady pay from your main job. Don't quit all at once. First, cut your hours little by little and then go from full-time to part-time hours. This gives you more time for your side work. But you still get some stable income, too.
**Spend More Time Growing Your Side Work Little by Little**
- Take those freed-up hours to focus on your side gig
- Use the time to get more customers and make more money
- Upgrade things like your website, marketing, products or services
- Reinvest profits back into growing the side business further
**Watch Your Income From the Side Job for Stability**
As you cut main job hours, see if side job income stays steady. Track your numbers closely each month. The money should be:
- Covering basic bills with some leftover
- Growing month to month as you put in more hours
- Replacing the pay you're losing from fewer main job hours
Only cut more main job hours when side income proves reliable. Don't take risks! Go at whatever pace lets you feel secure.
After slowly transitioning over time, you'll reach a point where your side gig is your main income source. Your hours at that old job can finally drop to zero. But only take this final step when the numbers show you're truly ready.
## Conclusion
When it's time to change direction, you must plan first. Every step needs preparation to help ensure success. From saving up cash reserves to understanding tax duties, careful planning removes stress. Moving slowly and watching for stability is wise, too. Transition at a pace allows your new income to grow steadily first.
With diligent preparation and patience, you can succeed! Turn that little side gig into your main money maker. The freedom and satisfaction of working for yourself make it all worthwhile. Just take your time getting there and build a strong foundation. Before you know it, your side hustle will be your full-time hustle! | kevin_c864b029545c2e7873d | |

As your project scales, you can always upgrade to a higher tier offering more servers and advanced functionalities.
4. Connect Your Cloud Provider. Forge integrates seamlessly with popular cloud providers like DigitalOcean and Amazon Web Services (AWS). If you don't already have an account with a cloud provider, you can usually sign up for a free trial during the Forge registration process.
**Pro Tip**: Consider your project's resource requirements when selecting a server size during provisioning. Forge offers a variety of server configurations, so you can choose the one that best suits your application's traffic and complexity. Don't hesitate to explore the documentation or reach out to Forge's support team if you have any questions about choosing the right plan or server size.
### Step 2: Connecting Your Cloud Provider
Once you've signed up for Laravel Forge and chosen a subscription plan, the next step is to connect your preferred cloud provider account. This allows Forge to interact with your cloud provider's API and seamlessly provision server instances on your behalf. Here's a breakdown of the process:
1. Navigate to the "Servers" Section. Within the Forge dashboard, locate the "Servers" section on the left-hand navigation menu.
2. Click "Add Server". This will initiate the server creation process.
3. Select Your Cloud Provider. Here, you'll see a list of supported cloud providers like DigitalOcean, AWS, and others. Choose the provider you've signed up for or plan to use.
4. Connect Using API Credentials. Each cloud provider has its own authentication method. Forge will typically guide you through the process of generating the necessary API credentials (access keys or tokens) within your cloud provider's account settings. Once you have these credentials, simply enter them into the corresponding fields in the Forge interface.
5. Grant Permissions. After entering your credentials, you might be prompted to authorize Forge to access your cloud provider account. This is a standard security measure. Carefully review the permissions being requested and grant them only if you're comfortable.
### Step 3: Server Configuration
With your cloud provider connection established, it's time to configure your first server on Laravel Forge. Here's where you define the specific characteristics of your server environment:
1. **Server Size**:
Forge offers a range of configurations, typically categorized by factors like CPU cores, memory (RAM), and storage capacity. Consider your application's expected traffic and resource usage to make an informed decision.
- **For smaller Laravel projects with low traffic**: A basic server with 1 CPU core, 1 GB of RAM, and 25 GB of storage might suffice.
- **For busier applications with more complex features**: You might opt for a server with 2-4 CPU cores, 4-8 GB of RAM, and 50 GB or more of storage.
2. **Server Location (Region)**:
Selecting the appropriate server region can significantly impact your application's performance. Ideally, choose a region geographically close to your target audience. This minimizes latency (response time) for users accessing your application.
3. **SSH Key Selection**:
Secure Shell (SSH) is a vital tool for server administration. During configuration, Forge allows you to select an existing SSH key pair or generate a new one. We highly recommend using an SSH key pair for secure server access instead of relying on passwords.
4. **Firewall Rules**:
While Forge comes with pre-configured firewalls for basic security, you can optionally customize firewall rules to further restrict access to your server. However, this is recommended for more advanced users comfortable with firewall configurations.
5. **Site Selection**:
If you plan to host [multiple Laravel applications](https://digimonksolutions.com/services/laravel-development/) on the same server, you can choose to create a new site during server configuration. This allows Forge to set up the necessary directory structure and configuration for your specific Laravel project.
Once you've made your selections for each configuration option, simply click "Create Server" and Forge will handle the server provisioning process.
### Step 4: Server Provisioning Process
With your server configuration finalized, it's time to witness the magic of Laravel Forge. Click "Create Server," and sit back as Forge seamlessly handles the entire server provisioning process. Here's a breakdown of what happens behind the scenes:
1. **Secure Connection**:
Forge utilizes SSH with your chosen SSH key pair to establish a secure connection to your cloud provider's infrastructure. This secure channel ensures the integrity and confidentiality of communication during server creation.
2. **Server Instance Launch**:
Based on your configuration, Forge instructs your cloud provider to launch a new server instance. This involves allocating resources like CPU cores, memory, and storage as specified during configuration.
3. **Operating System Installation**:
Forge automatically installs the desired operating system (typically a Linux distribution like Ubuntu) on the newly launched server instance.
4. **Software Stack Configuration**:
This is where Forge shines. It installs and configures all the essential software components required for running Laravel applications. This includes:
- **PHP**: The latest stable version of PHP, ensuring compatibility with your Laravel project.
- **Web Server** (e.g., Nginx): A web server optimized for serving web applications efficiently.
- **Database Server** (e.g., MySQL): A database management system for storing application data.
- **Additional Dependencies**: Composer, Redis, Memcached, and other libraries and tools crucial for Laravel functionality.
5. **Security Measures**:
Forge prioritizes security by implementing essential measures:
- **Automatic Updates**: Regular security updates are applied to the server software, keeping your environment patched against vulnerabilities.
- **Firewall Configuration**: Pre-configured firewall rules help protect your server from unauthorized access.
- **SSL Certificate**: Forge can automatically provision and manage SSL certificates, ensuring secure HTTPS connections for your application.
### Step 5: Verifying Server Provisioning
After the provisioning process completes, it's crucial to verify that your server is properly set up and ready to host your Laravel application. Here's how you can perform a thorough verification:
1. **SSH Login**:
- Use the SSH key pair you selected during configuration to log in to your server. Open your terminal and execute the following command (replace `your_server_ip` with the actual IP address of your server):
```bash
ssh forge@your_server_ip
```
- If the login is successful, you'll gain access to the server's command line interface.
2. **Check Installed Software**:
- Verify that PHP is installed and properly configured by running:
```bash
php -v
```
- Ensure the web server (e.g., Nginx) is running with:
```bash
sudo systemctl status nginx
```
- Confirm the database server (e.g., MySQL) is operational with:
```bash
sudo systemctl status mysql
```
3. **Verify Laravel Installation**:
- To ensure that Laravel is correctly installed and operational, navigate to your Laravel project's public directory and run:
```bash
cd /path/to/your/laravel/project/public
php artisan serve
```
- Open a web browser and access your server's IP address followed by the port number displayed in the terminal (usually `http://your_server_ip:8000`). You should see the default Laravel welcome page, indicating that the application is running successfully.
By following these verification steps, you can confidently confirm that your server is provisioned correctly and ready to host your Laravel application.
## Integrating Testing and Deployment
Once your server is up and running, it's time to focus on integrating automated testing and deployment strategies to streamline your development workflow.
### Testing Frameworks
Laravel provides robust support for automated testing, allowing you to ensure the quality and reliability of your application. Here's how to get started with testing frameworks like PHPUnit and Pest:
1. **PHPUnit**:
- PHPUnit is the default testing framework included with Laravel. You can write unit tests, feature tests, and browser tests to validate different aspects of your application.
- Create a sample test case in the `tests/Feature` directory and run the tests with:
```bash
php artisan test
```
2. **Pest**:
- Pest is a delightful PHP testing framework with a focus on simplicity and readability. It can be used alongside or as an alternative to PHPUnit.
- To install Pest, run:
```bash
composer require pestphp/pest --dev
```
- Create a new test case using Pest syntax and execute the tests with:
```bash
php artisan pest
```
By incorporating automated testing into your workflow, you can catch bugs early and ensure that your application functions as expected.
### Leveraging Forge for Deployment Automation
Laravel Forge simplifies the deployment process by integrating seamlessly with Git repositories and providing tools for automated deployments. Here's how you can leverage Forge for deployment automation:
1. **Git Repository Integration**:
- Connect your Git repository (GitHub, GitLab, or Bitbucket) to Forge. This allows Forge to pull the latest code changes from your repository during deployment.
- In the Forge dashboard, navigate to your server's settings and configure the repository details.
2. **Deployment Scripts**:
- Define custom deployment scripts to automate tasks during deployment. For example, you can run database migrations, clear caches, or install dependencies.
- Create a `deploy.sh` script in your project root directory and add commands like:
```bash
#!/bin/bash
cd /path/to/your/laravel/project
php artisan migrate --force
php artisan cache:clear
```
3. **Zero-Downtime Deployment**:
- Forge supports zero-downtime deployment strategies, ensuring that your application remains available to users during updates.
- Enable zero-downtime deployment in the Forge settings to minimize disruptions during code deployments.
By integrating Forge with your Git repository and configuring deployment scripts, you can achieve a streamlined and automated deployment process, reducing the risk of errors and downtime.
## Additional Considerations
To maximize the efficiency and security of your server provisioning and deployment process, consider the following additional considerations:
### Security Best Practices
1. **Environment Variables**:
- Use environment variables to store sensitive information like API keys and database credentials. Forge supports managing environment variables securely within the dashboard.
2. **Monitoring and Performance**:
- Implement monitoring tools like New Relic or Prometheus to gain insights into your server's performance and detect potential issues early.
### Advanced Configuration
1. **Scaling and Load Balancing**:
- As your application grows, consider scaling your infrastructure horizontally by adding more servers and implementing load balancing.
2. **Backup and Disaster Recovery**:
- Regularly back up your database and application files to ensure that you can recover quickly in case of data loss or server failures.
