1,886,612 | Dive into Server-Side Website Programming: From Basics to Mastery🚀🚀 | Introduction to Server-Side Programming Server-Side Website... | 0 | 2024-06-13T07:21:08 | https://dev.to/dharamgfx/dive-into-server-side-website-programming-from-basics-to-mastery-255f | webdev, javascript, node, beginners |
### Introduction to Server-Side Programming
#### Server-Side Website Programming
Server-side programming involves writing code that runs on a server, handling requests from clients (typically web browsers), processing these requests, interacting with databases, and sending appropriate responses back to the client. This is essential for creating dynamic, interactive, and data-driven websites.
**Example:**
- **Client Request:** User submits a login form on a website.
- **Server Processing:** The server validates the credentials against a database.
- **Server Response:** If valid, the server sends a success message; otherwise, an error message.
### First Steps in Server-Side Programming
#### Getting Started with Server-Side Programming
1. **Choose a Programming Language:**
- Popular choices include JavaScript (Node.js), Python (Django), Ruby (Ruby on Rails), PHP, and Java (Spring).
2. **Set Up Your Development Environment:**
- Install necessary software (e.g., Node.js for JavaScript).
- Choose a code editor (e.g., VS Code, Sublime Text).
#### Introduction to the Server Side
The server side, also known as the back end, is where the core functionalities of a website are handled. This includes database operations, user authentication, and business logic.
**Example:**
- **Scenario:** Fetching user data from a database when a profile page is requested.
- **Process:**
- The client sends a request to view a profile.
- The server queries the database for user information.
- The server processes and formats the data.
- The server sends the formatted data back to the client.
#### Client-Server Overview
The client-server model is a distributed application structure that partitions tasks between servers and clients.
- **Client:** Requests services/resources.
- **Server:** Provides services/resources.
**Example:**
- **Client:** Browser requests the homepage of a website.
- **Server:** Sends the HTML, CSS, and JavaScript files necessary to render the homepage.
### Server-Side Web Frameworks
#### Exploring Server-Side Web Frameworks
Frameworks streamline development by providing tools and libraries for common tasks. Popular server-side frameworks include:
- **Express (Node.js/JavaScript)**
- **Django (Python)**
- **Ruby on Rails (Ruby)**
- **Laravel (PHP)**
- **Spring (Java)**
**Example:**
- Using **Express**, you can set up routes to handle different URL endpoints and manage HTTP requests and responses easily.
### Website Security
#### Ensuring Website Security
Security is crucial to protect data and maintain user trust. Key aspects include:
- **Authentication:** Verifying user identities.
- **Authorization:** Controlling user access to resources.
- **Data Encryption:** Protecting data in transit and at rest.
- **Input Validation:** Preventing malicious input (e.g., SQL injection, XSS).
**Example:**
- **Cross-Site Scripting (XSS):**
- **Problem:** Malicious scripts injected into webpages.
- **Solution:** Sanitize user inputs to remove harmful scripts.
### Deep Dive into Express Web Framework (Node.js/JavaScript)
#### Express/Node Introduction
Express is a minimal and flexible Node.js web application framework that provides a robust set of features to develop web and mobile applications.
**Example:**
```javascript
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send('Hello World!');
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
#### Setting Up a Node Development Environment
1. **Install Node.js and npm:**
- Download and install from [Node.js website](https://nodejs.org/).
2. **Initialize a Project:**
- Use `npm init` to create a package.json file.

mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true });
const Schema = mongoose.Schema;
const BookSchema = new Schema({
title: String,
author: String,
published_date: Date
});
const Book = mongoose.model('Book', BookSchema);
```
#### Part 3: Routes and Controllers
1. **Define Routes:**
- Create route files for different sections of the website.
2. **Create Controllers:**
- Implement business logic in controller functions.
**Example:**
```javascript
const express = require('express');
const router = express.Router();
router.get('/', (req, res) => {
res.send('Library Home Page');
});
module.exports = router;
```
#### Part 4: Displaying Library Data
1. **Fetch Data from Database:**
- Use Mongoose models to query the database.
2. **Render Views:**
- Pass data to views to generate dynamic HTML.
**Example:**
```javascript
router.get('/books', async (req, res) => {
const books = await Book.find();
res.render('books', { books: books });
});
```
#### Part 5: Working with Forms
1. **Handle Form Submissions:**
- Set up routes to process form data.
2. **Validate and Sanitize Input:**
- Ensure data integrity and security.
**Example:**
```javascript
router.post('/add-book', (req, res) => {
const newBook = new Book(req.body);
newBook.save((err) => {
if (err) return res.send(err);
res.redirect('/books');
});
});
```
#### Part 6: Deploying to Production
1. **Prepare for Deployment:**
- Optimize code and assets.
2. **Choose a Hosting Service:**
- Examples include Heroku, AWS, and DigitalOcean.
3. **Deploy Your Application:**
- Follow the specific steps for your chosen hosting service.
**Example:**
- **Heroku Deployment:**
- `heroku create`
- `git push heroku main`
### Additional Topics
#### Advanced Routing
1. **Nested Routes:**
- Define routes within other routes for better organization.
2. **Parameterized Routes:**
- Use route parameters to handle dynamic content.
**Example:**
```javascript
router.get('/books/:id', async (req, res) => {
const book = await Book.findById(req.params.id);
res.render('book', { book: book });
});
```
#### Middleware
1. **Third-Party Middleware:**
- Use middleware for logging, authentication, and more.
2. **Custom Middleware:**
- Create middleware to handle specific tasks.
**Example:**
```javascript
app.use((req, res, next) => {
console.log('Time:', Date.now());
next();
});
```
#### Error Handling
1. **Centralized Error Handling:**
- Use middleware to manage errors globally.
2. **Custom Error Pages:**
- Display user-friendly error messages.
**Example:**
```javascript
app.use((err, req, res, next) => {
console.error(err.stack);
res.status(500).send('Something broke!');
});
```

1,886,611 | Code Smell, Cyclomatic Complexity, Blast Radius, Heisenbug and more... | We often read about design principles and design patterns, but it's equally important to understand... | 0 | 2024-06-13T07:20:57 | https://dev.to/rahulvijayvergiya/code-smell-cyclomatic-complexity-blast-radius-heisenbug-and-more-4kp3 | webdev, programming, architecture, designsystem | We often read about design principles and design patterns, but it's equally important to understand the specific challenges they help us address.
This article highlights key topics such as **Service Mesh, Failover, Dependency Hell, Ripple Effect, Single Point of Failure (SPOF), Cyclomatic Complexity, Blast Radius, God Object, Heisenbug, and Code Smell**.
Whether you are a seasoned developer or just starting out, mastering these concepts will help you navigate the complexities of modern software architecture and development.
## 1. Code Smell
Indicators in the source code that suggest potential deeper problems. These are often subtle hints that there might be a larger issue in the code, such as poor design choices or violations of fundamental design principles. Identifying and addressing code smells through refactoring can improve code readability, maintainability, and overall quality.
**Example:** A long method with many parameters and nested loops is a code smell; refactoring it into smaller, more manageable methods can improve readability and maintainability.
---
## 2. Cyclomatic Complexity
A metric that measures the complexity of a program by quantifying the number of linearly independent paths through the source code.It is used to indicate the complexity of a program, where a higher value suggests more complex and potentially harder-to-maintain code.
**Example:** A function with many nested conditionals will have high cyclomatic complexity, indicating a need for simplification, possibly by breaking it into smaller, single-responsibility functions.
---
## 3. Blast Radius
The extent of impact caused by a failure within a system. it signifies the scope of parts affected by a change or a failure. Minimising the blast radius involves designing systems in a way that localises failures, thereby reducing their impact on the overall system.
**Example: **In a microservices architecture, a failure in one microservice should ideally not affect others, using techniques like circuit breakers can help minimise the blast radius.
---
## 4. Heisenbug
A bug that changes behaviour or disappears when one attempts to study it cause. it highlights the elusive nature of some bugs, which can make them difficult to reproduce and fix.
**Example:** A multi-threaded program might show a bug that disappears when running in debug mode due to the altered timing of threads, making it hard to reproduce and fix.
---
## 5. Service Mesh
A dedicated infrastructure layer for managing service-to-service communication in microservices architectures. It can handles network functions like load balancing, authentication, and observability. This allow developers to focus on the core logic of their applications without worrying about the intricacies of network communication.
**Example:** In Kubernetes, Istio can be used as a service mesh to handle routing, load balancing, and security for microservices without requiring changes to the application code.
---
## 6. Failover
Description: A backup operational mode where secondary systems take over if the primary system fails. It ensures high availability and reliability by automatically switching to a standby database, server, or network if the primary one fails.
**Example:** In a database setup, if the primary database server goes down, a failover system automatically switches operations to a secondary replica to ensure continuous availability.
---
## 7. Dependency Hell
Description: Complexity and conflicts arising from multiple software packages depending on different versions of the same dependencies. This can lead to a situation where it becomes challenging to resolve these dependencies without conflicts, making software maintenance difficult.
**Example:**
- Version Conflict: A project requires Library A version 1.0 and Library B version 2.0. However, Library A version 1.0 is not compatible with Library B version 2.0, leading to runtime errors or unexpected behavior.
- Circular Dependency: Library X depends on Library Y, and Library Y depends on Library X. This circular dependency makes it difficult to determine which library to install first or causes issues during compilation or linking.
---
## 8. Ripple Effect
A small change in one part of a system causing cascading changes throughout. This underscores the importance of understanding the interdependencies within a codebase, as seemingly minor modifications can lead to significant unintended consequences.
**Example:** Updating a core library in a project might necessitate changes in multiple dependent modules and require extensive regression testing to ensure nothing breaks.
---
## 9. Single Point of Failure (SPOF)
A component whose failure can stop the entire system from working. Identifying and mitigating SPOFs is crucial for building resilient and reliable systems.
**Example:** A single database server without replication or backup represents an SPOF; adding replication and load balancers mitigates this risk.
---
## 10. God Object
An object that has too many responsibilities, violating the single responsibility principle. This anti-pattern results in a class that has excessive responsibilities, leading to code that is difficult to maintain, test, and understand. Refactoring God Objects into smaller, more focused classes helps improve code quality and maintainability.
**Example:** A class that handles user authentication, database interactions, and UI updates should be refactored into separate classes, each with a single focus, to avoid becoming a God object.
---
## Conclusion:
These article serve as an introduction and i encourage you to further explore each of them. Understanding these principles enables developers to design and maintain software systems that are resilient and manageable.

With the ever-growing number of mobile... | 0 | 2024-06-13T07:08:48 | https://dev.to/aditya_pandey_1847fe5a44a/why-mobile-optimization-is-crucial-for-your-website-in-2024-94o |
Mobile optimization is no longer optional — it’s essential. With the ever-growing number of mobile users worldwide, ensuring your website is mobile-friendly can make or break your online presence. As the best digital marketing company in Varanasi, we understand the importance of keeping up with digital trends to help your business thrive. Here’s why mobile optimization is crucial for your website this year.
1. The Mobile User Surge
The number of people accessing the internet via mobile devices has skyrocketed. According to recent studies, over 60% of global web traffic comes from mobile devices. This means that if your website isn’t optimized for mobile, you’re potentially missing out on a significant chunk of your audience. Ensuring a seamless mobile experience can keep visitors engaged and increase your chances of converting them into customers.
2. Google’s Mobile-First Indexing
In response to the mobile trend, Google has implemented mobile-first indexing. This means that Google predominantly uses the mobile version of your site for indexing and ranking. If your website isn’t optimized for mobile, it could suffer in search engine rankings, making it harder for potential customers to find you. Partnering with the best digital marketing company in Varanasi can help you ensure your site is optimized for these new search engine requirements.
3. Enhanced User Experience
A well-optimized mobile website provides a better user experience. Mobile users expect fast-loading pages, easy navigation, and content that fits their screens. If your site takes too long to load or is difficult to navigate on a mobile device, visitors are likely to leave, increasing your bounce rate. A mobile-optimized site keeps visitors engaged and encourages them to stay longer, exploring more of what you offer.
4. Increased Conversion Rates
Improved user experience on mobile devices directly translates to higher conversion rates. When users can easily navigate your site, find what they need, and complete transactions without hassle, they are more likely to convert. As the best digital marketing company in Varanasi, we emphasize the importance of mobile optimization to drive conversions and boost your bottom line.
5. Competitive Advantage
In today’s competitive market, having a mobile-optimized website can give you an edge over competitors who haven’t adapted to this trend. Mobile optimization can enhance your brand’s credibility and professionalism, making you more appealing to potential customers. Staying ahead of the curve with a mobile-friendly website demonstrates your commitment to providing the best user experience.
6. Local SEO Benefits
Mobile optimization plays a crucial role in local SEO. Many users perform local searches on their mobile devices to find businesses nearby. A mobile-friendly website is more likely to appear in local search results, driving more traffic to your site and potentially increasing foot traffic to your physical location. As the best digital marketing company in Varanasi, we can help you leverage mobile optimization to enhance your local SEO efforts.
Conclusion
Mobile optimization is no longer a luxury — it’s a necessity. With the growing dominance of mobile internet usage, optimizing your website for mobile devices is crucial for staying relevant and competitive in 2024. Whether it’s improving user experience, boosting your search engine rankings, or increasing conversion rates, mobile optimization offers numerous benefits for your business. | aditya_pandey_1847fe5a44a | |
1,886,589 | What is CJIS Compliance? | The Comprehensive Guide to CJIS Compliance: Safeguarding Criminal Justice Information In... | 0 | 2024-06-13T07:08:41 | https://dev.to/blogginger/what-is-cjis-compliance-7lg | cjiscompliance, cjis | ### The Comprehensive Guide to CJIS Compliance: Safeguarding Criminal Justice Information
In today’s digital world, data security is critical, especially within law enforcement and public safety sectors. CJIS compliance is a crucial framework for protecting sensitive information. But what does CJIS compliance entail, and why is it so vital? This guide explores the essential aspects of CJIS compliance, providing a thorough understanding of its significance, requirements, and implementation strategies.
#### What is CJIS?
Lets Explore [What is CJIS](https://www.authx.com/blog/what-is-cjis-compliance/?utm_source=devto&utm_medium=SEO&utm_campaign=blog&utm_id=K003) (Criminal Justice Information Services) is the largest division of the Federal Bureau of Investigation (FBI), established in 1992. CJIS serves as a central repository for criminal justice information, providing data on fingerprints, criminal histories, and other essential law enforcement information to federal, state, and local agencies.
#### The Importance of CJIS Compliance
CJIS compliance refers to adhering to the FBI's CJIS Security Policy, which outlines the necessary security measures for protecting Criminal Justice Information (CJI). Given the sensitive nature of CJI, stringent safeguards are essential to prevent unauthorized access, breaches, and misuse. Ensuring CJIS compliance is critical for maintaining public trust and the integrity of law enforcement operations.
#### Key Components of CJIS Compliance
The CJIS Security Policy encompasses various dimensions of data security. Here are the key components:
1. **Information Exchange Agreements**: Organizations accessing CJI must establish formal agreements detailing the terms, conditions, and security measures for data sharing and use. These agreements ensure that all parties understand and commit to the required security standards.
2. **Security Awareness Training**: Personnel with access to CJI must undergo regular security awareness training. This training educates staff on the latest security threats, policies, and best practices, ensuring they are well-prepared to handle sensitive information securely.
3. **Audits and Accountability**: Regular audits are conducted to verify compliance with CJIS standards. Organizations must maintain detailed logs and records of data access and usage, ensuring transparency and accountability. These audits help identify and rectify any security gaps or violations.
4. **Physical Security**: Physical security measures are crucial for protecting CJI. Secure facilities with controlled access, surveillance, and physical barriers are necessary to prevent unauthorized entry and physical breaches.
5. **Encryption**: Data encryption is mandatory both during transmission and at rest. Encryption ensures that even if data is intercepted or accessed without authorization, it remains unreadable and secure.
6. **Access Control**: Strict access control measures are implemented to ensure that only authorized personnel can access CJI. This includes multi-factor authentication (MFA), role-based access control (RBAC), and the principle of least privilege.
7. **Incident Response**: Organizations must have a robust incident response plan to address security breaches and incidents promptly. This plan should include procedures for detecting, reporting, and mitigating breaches, as well as recovery strategies to minimize impact.
8. **Personnel Security**: Comprehensive background checks are required for individuals who will access CJI. This ensures that only trustworthy and vetted personnel are granted access to sensitive information.
#### Who Needs to Be CJIS Compliant?
CJIS compliance is essential for any organization that handles CJI. This includes:
- **Law Enforcement Agencies**: Police departments, sheriff’s offices, and other law enforcement bodies are directly responsible for managing and protecting CJI.
- **Public Safety Organizations**: Agencies involved in emergency response and public safety, such as fire departments and emergency medical services, must also comply with CJIS standards.
- **Private Contractors**: Companies that provide services to law enforcement and public safety agencies, including IT service providers, cloud service providers, and other third-party vendors, must adhere to CJIS compliance requirements.
#### Challenges in Achieving CJIS Compliance
Achieving and maintaining CJIS compliance can be challenging due to the rigorous standards and frequent updates to the CJIS Security Policy. Some common challenges include:
- **Keeping Up with Policy Changes**: The CJIS Security Policy is regularly updated to address emerging threats and technological advancements. Staying current with these changes is crucial for maintaining compliance.
- **Resource Allocation**: Ensuring adequate resources for training, audits, and security measures can be demanding, especially for smaller agencies and organizations with limited budgets.
- **Integration with Existing Systems**: Implementing CJIS-compliant systems often requires significant changes to existing IT infrastructure, which can be complex and costly.
#### Steps to Achieving CJIS Compliance
Achieving CJIS compliance involves a comprehensive and systematic approach. Here are the essential steps:
1. **Conduct a Risk Assessment**: Identify potential vulnerabilities and areas where security measures need to be strengthened. This assessment helps prioritize actions and allocate resources effectively.
2. **Develop Policies and Procedures**: Create detailed policies and procedures aligned with the CJIS Security Policy. These documents should outline the organization’s approach to data protection, incident response, and compliance.
3. **Implement Security Measures**: Deploy the necessary technical and physical security controls to protect CJI. This includes encryption, access control, and physical security measures.
4. **Regular Training**: Ensure that all personnel with access to CJI receive ongoing training on security practices, compliance requirements, and the latest threats. Training should be updated regularly to reflect new policies and emerging risks.
5. **Monitor and Audit**: Continuously monitor systems for compliance and conduct regular audits to ensure adherence to CJIS standards. Monitoring and auditing help identify and address any compliance issues proactively.
#### Conclusion
CJIS compliance is not just a regulatory requirement; it is a fundamental aspect of safeguarding criminal justice information. By adhering to the [CJIS Security](https://www.authx.com/cjis/?utm_source=devto&utm_medium=SEO&utm_campaign=blog&utm_id=K003) Policy, organizations can ensure the protection of sensitive data, maintain public trust, and enhance the effectiveness of law enforcement and public safety efforts.
While achieving CJIS compliance can be complex and resource-intensive, it is essential for any organization handling CJI. By following best practices, staying updated with policy changes, and implementing robust security measures, organizations can successfully navigate the challenges and maintain a high level of data security. | blogginger |

This article highlights the critical role of website loading speed in online business success. A slow website frustrates visitors and hurts SEO ranking. Here are 10 effective ways to improve your website speed:
1. **Reliable Hosting**: Choose a hosting provider that prioritizes speed and scalability. WeWP is mentioned as an example of such a provider.
2. **Image Optimization**: Compress images using tools or plugins like TinyPNG or by adjusting their size and format. Utilize modern formats like WebP for superior compression.
3. **Minimize Redirects**: Avoid unnecessary redirects (URL forwarding) as they slow down loading times.
4. **Remove Unused Plugins**: Deactivate or delete plugins that are no longer needed. Plugins add extra code that needs to load, impacting speed.
5. **Compress Files with Gzip**: This protocol reduces the size of HTML, CSS, and JavaScript files for faster loading. Brotli compression offers even better results.
6. **Reduce HTTP Requests**: Fewer files on your page mean fewer requests the browser needs to make, leading to faster loading.
7. **Optimize CSS and JavaScript**: Minify these files by removing unnecessary characters and comments, resulting in smaller file sizes.
8. **Activate Browser Caching**: This stores website data on visitors’ devices so they don’t need to download it again on subsequent visits, speeding up page load times.
9. **Use a Content Delivery Network (CDN)**: A CDN distributes your website content across geographically dispersed servers, allowing users to access it faster regardless of location.
10. **Maintain a Clean Database**: Regularly remove unnecessary data, optimize tables, and create indexes in your website’s database for faster query execution and page loading.

1,886,582 | Understanding the Difference Between APIs and Endpoints | Understanding the Difference Between APIs and Endpoints In the world of software... | 0 | 2024-06-13T06:58:18 | https://dev.to/msnmongare/understanding-the-difference-between-apis-and-endpoints-402a | api, webdev, beginners, abotwrotethis | ### Understanding the Difference Between APIs and Endpoints
In the world of software development, particularly in the domain of web services and backend development, two terms frequently surface: API (Application Programming Interface) and endpoints.” They are always associated, but, nevertheless, they are two concepts that are quite different. The main focus of this article is designed to explain APIs and endpoints separately and bring clarity to the relationship they have with each other.
#### What is an API?
An application program interface (API) is a kind of tool, protocol, and other programming methodology that is used in the software construction. It specifies the format of data, how applications will share it, and the protocols that should be followed. In other words, it involves the use of an interface that supports interaction between two application domains.
##### Key Characteristics of an API:
- **Definition**: API refers to a structured collection of specifications within the interaction between computer programs that provide clear guidelines as well as descriptions.
- **Scope**: Due to this, it provides various options and it is possible to introduce multiple endpoints, functions or methods.
- **Purpose**: The reason actualization is possible with APIs is due to the fact that it allows for one system to present a uniform interface to another system so that the latter can make use of other systems if it needed to do so.
- **Examples**: Some of the most widely known types of API are, RESTful, SOAP, and GraphQL.
#### What is an Endpoint?
An endpoint, in contrast to an API, defines a URL or URI in the API where one can provide or request specific data or action. It is the precise reference point which is used by clients, developers or other users for accessing APIs whether these clients are browsers, mobiles or other servers.
##### Key Characteristics of an Endpoint:
- **Definition**: Endpoint is a specific point in an API designating a particular operation, line function or service, normally one call.
- **Scope**: It is a component of the API most often used to refer to a function, including simple access to information or for handling changes to a resource or an event.
- **Purpose**: API destinations are the URLs where API calls are made which can be as simple as just a URL where a request can be made to. They specify the coordinates or conditions necessary for reaching a specific resource or method.
- **Examples**: Some of the include:
- It includes :
- `GET /api/users` – which returns a list of users.
- `POST /customers` – This will create a new customer or user
- `GET /api/users/{id} – returns information about a specific user using their unique identifier.
- `PUT /api/users/ {id} – This endpoint allows to update one particular user using their identifier.
- `DELETE /api/users/{id}:` Used to delete a specific user based on the user’s id.
#### The Relationship Between APIs and Endpoints
By analogy, it is possible to compare an API to a library; whereas endpoints can be compared to specific books at this library. API gives you the organization of the library that is the outer shell and regulation of how the library functions while the endpoints are the exact places where a particular piece of information can be found or accessed.
- **API as a Library**: Similarly as a library has a set of books, an API also has a set of endpoints but it means that each of them has its own purpose.
- **Endpoints as Books**: Within API, each endpoint is similar to a book in a library since API can be considered as a library where one can find books on a given subject in general and can directly turn to the book in question that can contain the required information.
#### Practical Implications
This is an important knowledge for developers to distinguish the difference between APIs and endpoints. When designing or interacting with an API, it’s important to grasp that:When designing or interacting with an API, it’s important to grasp that:
- API stands for Application Programming Interface, which essentially forms a structure and set of guidelines for communication.
- The endpoint is defined as the certain individual contact points in which information and facilities may be requested.
This enables us to recognize the areas that needs design changes to fit the intended improvements to develop more efficient and order ways of running the systems. It also helps in identifying bugs since a developer can tell whether a problem originating from the overall architecture of the API or from a particular endpoint.
#### Conclusion
Thus, APIs and endpoints are interconnected, and to distinguish them, it is necessary to consider their positions in the context of software development. An API is the overreaching definition of standards along with specifications of the software systems’ ability to exchange data while End Points are the particular locations where the API interchange takes place within a specific API. | msnmongare |

For beginners, understanding the basics of CFD trading is crucial for making informed decisions and managing risks effectively. This guide will cover the fundamental aspects of CFD trading, focusing on [forex](https://bit.ly/forex-trading-t4t), trading, [markets](https://bit.ly/forex-markets-t4t-seo), CFDs, and broker platforms.
**What is CFD Trading?**
CFD trading involves entering into a contract with a broker to exchange the difference in the value of an asset from the time the contract is opened to when it is closed. Unlike [traditional trading](https://bit.ly/forex-trading-T4t), where you own the asset, CFDs allow you to speculate on price movements. This can be beneficial for both rising and falling markets.
Key Features of CFD Trading
1. Leverage
• CFDs are leveraged products, meaning you can open a larger position than your initial investment. Leverage can amplify both profits and losses, making it important to use it wisely.
2. Margin Trading
• To trade CFDs, you need to deposit a percentage of the trade’s total value, known as the margin. This initial deposit allows you to control a larger position in the market.
3. Going Long and Short
• CFDs allow you to profit from both rising (going long) and falling (going short) markets. If you anticipate that the price of an asset will rise, you open a long position. Conversely, if you expect the price to fall, you open a short position.
4. Market Access
• CFD trading provides access to a wide range of markets, including forex, commodities, indices, and shares. This allows for diversification and the ability to trade various asset classes from a single broker platform.
Benefits of CFD Trading
1. Flexibility
• CFDs offer the flexibility to trade a wide range of financial instruments and access global markets.
2. No Ownership of Assets
• Since CFDs do not involve ownership of the underlying asset, there are no costs associated with physical ownership, such as storage fees for commodities or management fees for properties.
3. Hedging Opportunities
• CFDs can be used to hedge existing investments. For example, if you own shares and expect their value to drop, you can use CFDs to offset potential losses by opening a short position.
Risks of CFD Trading
1. Leverage Risk
• While leverage can increase potential profits, it also amplifies potential losses. It is important to manage leverage carefully and understand its impact on your trading.
2. Market Volatility
• CFD markets can be highly volatile, leading to rapid price changes. This requires constant monitoring and quick decision-making.
3. Counterparty Risk
• CFD trading involves a contract with a broker, introducing counterparty risk. Ensure you trade with a regulated and reputable broker to mitigate this risk.
Choosing a Broker Platform for CFD Trading
Selecting the right broker is crucial for successful CFD trading. Here are key factors to consider:
1. Regulation and Security
• Ensure the broker is regulated by reputable financial authorities such as the Financial Conduct Authority (FCA), the Australian Securities and Investments Commission (ASIC), or the U.S. Securities and Exchange Commission (SEC). This provides a level of security and ensures the broker adheres to industry standards.
2. Trading Platforms
• Evaluate the broker's trading platform for its user-friendliness, reliability, and features. Popular [platforms](https://bit.ly/3VhMfhU) include MetaTrader 4 (MT4), MetaTrader 5 (MT5), and cTrader, which offer advanced charting tools, technical indicators, and automated trading capabilities.
3. Trading Costs
• Compare the broker's fee structure, including spreads, commissions, and overnight financing fees (swap fees). Lower trading costs can enhance your overall profitability.
4. Customer Support
• Reliable customer support is essential for resolving issues and answering queries promptly. Evaluate the broker's customer service by contacting them through various channels such as live chat, email, or phone.

This allows for greater reusability and flexibility when building user interfaces. Here’s a comprehensive overview of headless components in React:
### What are Headless Components?
Headless components, also known as logic components or controller components, manage the state and behavior of a UI without dictating how it should be rendered. This separation allows developers to reuse the logic across different UI components without being tied to a specific design.
### Benefits of Headless Components
1. **Reusability**: The same logic can be reused with different UI presentations.
2. **Flexibility**: Easily change the UI without affecting the underlying logic.
3. **Maintainability**: Simplifies component maintenance by separating concerns.
4. **Testability**: Easier to test logic independently from the UI.
### How to Implement Headless Components
#### Example: Headless Toggle Component
1. **Create the Headless Component**
```javascript
import { useState } from 'react';
const useToggle = (initialState = false) => {
const [state, setState] = useState(initialState);
const toggle = () => setState(prevState => !prevState);
return [state, toggle];
};
export default useToggle;
```
2. **Use the Headless Component in Different Presentational Components**
**ToggleButton.jsx**
```javascript
import React from 'react';
import useToggle from './useToggle';
const ToggleButton = () => {
const [isOn, toggle] = useToggle(false);
return (
<button onClick={toggle}>
{isOn ? 'ON' : 'OFF'}
</button>
);
};
export default ToggleButton;
```
**ToggleSwitch.jsx**
```javascript
import React from 'react';
import useToggle from './useToggle';
const ToggleSwitch = () => {
const [isOn, toggle] = useToggle(false);
return (
<div onClick={toggle} style={{ cursor: 'pointer' }}>
<div>{isOn ? 'ON' : 'OFF'}</div>
<div
style={{
width: '40px',
height: '20px',
background: isOn ? 'green' : 'red',
position: 'relative',
transition: 'background 0.3s',
}}
>
<div
style={{
width: '20px',
height: '20px',
background: 'white',
position: 'absolute',
left: isOn ? '20px' : '0',
transition: 'left 0.3s',
}}
/>
</div>
</div>
);
};
export default ToggleSwitch;
```
### Best Practices for Headless Components
1. **Keep them focused**: Each headless component should manage a single piece of logic.
2. **Use hooks**: React hooks are a great way to implement headless components as they naturally separate logic from UI.
3. **Document thoroughly**: Since the headless component won’t include any UI, ensure that the API and usage are well-documented.
4. **Think composition**: Use headless components as building blocks that can be composed together to form complex UI elements.
### Conclusion
Headless components in React offer a powerful way to create reusable, maintainable, and flexible components by separating logic from presentation. By adopting this pattern, you can build more scalable and testable applications. | webdevlapani |

1,885,534 | A Comprehensive Guide to XSS Attacks and Defenses | Part 1: Basics of Vulnerability Attacks and Defenses XSS belongs to the field of... | 0 | 2024-06-13T06:44:45 | https://dev.to/wetest/a-comprehensive-guide-to-xss-attacks-and-defenses-39m8 | programming, xss | ## **Part 1: Basics of Vulnerability Attacks and Defenses**
XSS belongs to the field of vulnerability attacks and defenses. To study it, we need to understand some jargon in this field for better communication and exchange. At the same time, I have established a simple attack model for XSS vulnerability learning.
## 1. Vulnerability Terminology
**VUL**
Vulnerability (VUL) refers to bugs that can cause damage to a system or can be used to attack a system.
**POC**
Proof of Concept (POC) is the evidence of a vulnerability; it can be a textual description and screenshot proving the existence of a vulnerability, but more often, it is the code that proves the vulnerability's existence. Generally, it does not damage the vulnerable system.
**EXP**
Exploit (EXP) is the code used to attack a system using a vulnerability.
**Payload**
Payload is the attack code that you include in an exploit.
**PWN**
PWN is a slang term in hacker language, referring to breaking a device or system.
**Zero-day Exploit and Zero-day Attack**
Zero-day exploit usually refers to a security vulnerability that has no patch available.
Zero-day attack refers to an attack exploiting such a vulnerability.
Zero-day exploit is not only the favorite of hackers, but the number of zero-day exploit mastered is also an important parameter to evaluate a hacker's technical level.
**CVE Vulnerability Number**
Common Vulnerabilities and Exposures (CVE) assigns a public name to widely recognized information security vulnerabilities or exposed weaknesses.
You can search for an introduction to the vulnerability on the https://cve.mitre.org/ website based on the CVE number of the vulnerability.
## 2. Vulnerability Attack Model
The diagram above shows a simple attack model. An attack is the process of injecting the Payload through the injection point and executing it at the execution point. If the process goes smoothly, it indicates that the vulnerability has been exploited.
## **Part 2: XSS Fundamentals**
## 1. What's XSS?
XSS stands for Cross-site scripting. Attackers exploit the injection point of a website to insert malicious code (Payload) that can be executed and parsed on the client-side. When the victim visits the website, this malicious code is executed at the client's execution point, achieving the attacker's goals, such as obtaining user permissions, malicious propagation, phishing, and other behaviors.
## 2. Classification of XSS
It is difficult to learn XSS well without understanding its classification. There are many misunderstandings about the classification of XSS, and many articles explain it incorrectly. Here, I provide a relatively good classification of XSS.
**2.1 Classification by Payload Source**
**Stored XSS** is a type of cross-site scripting attack in which the malicious code (Payload) is permanently stored on the server. Therefore, it is also called persistent XSS. When the browser requests data, the data containing the Payload is uploaded from the server and executed on the client-side.
The process is shown in the diagram:
**An example of a stored XSS attack**: The attacker includes the malicious code (Payload) in the content of the posted message, which is then stored in the database. When the victim visits the page containing the message, the malicious code (Payload) is executed.
**Reflected XSS** is a type of cross-site scripting attack, also known as non-persistent XSS. In the first scenario, the Payload originates from the client-side and is executed directly on the client-side. In the second scenario, the temporary data sent from the client to the server is processed and then directly echoed back to the client-side for execution.
The process is shown in the diagram:
**Two examples of reflected XSS attacks:**
1. The attacker spreads a link containing the Payload, and when the victim visits this link, the Payload is executed on the client-side.
2. The victim enters content containing the Payload into the client-side search box, and the server echoes back a page indicating that the search content was not found, at which point the Payload is executed.
**2.2 Classification by Payload Location**
**DOM-based XSS** refers to a type of cross-site scripting attack that occurs when client-side JavaScript code manipulates the DOM (Document Object Model) or BOM (Browser Object Model), causing the Payload (malicious code) to execute. Since the execution of the Payload is primarily due to the manipulation of the DOM, it is called DOM-based XSS. However, manipulating the BOM can also cause the Payload to execute, so this term is somewhat inaccurate, and calling it JavaScript-based XSS would be more appropriate.
The Payload in DOM-based XSS is not in the HTML code, which brings difficulties to automated vulnerability detection.
**The process is shown in the diagram:**
**Reflected DOM-based XSS example**: The victim enters content containing the Payload into the client-side search box, and the server echoes back a page indicating that the search content was not found, at which point the Payload is executed.
**Stored DOM-based XSS example**: The client retrieves content containing the Payload from the server API, and then JavaScript manipulates the DOM or BOM, causing the Payload to execute.
**HTML-based XSS** refers to a type of cross-site scripting attack in which the malicious code (Payload) is included in the HTML returned by the server. When the browser parses the HTML, the malicious code is executed. This type of vulnerability is easier to perform automated vulnerability detection because the Payload is located within the HTML code. Of course, HTML-based XSS can also be classified as reflected and stored.
**The process is shown in the diagram:**
**Reflected HTML-based XSS example**: The victim enters content containing the Payload into the client-side search box, and the server echoes back a page indicating that the search content was not found, at which point the Payload is included in the HTML and executed.
**Stored HTML-based XSS example**: The attacker includes the malicious code (Payload) in the content of the posted message, which is then stored in the database. When the victim visits the page containing the message, the Payload is executed within the HTML page.
## 3. XSS Attack Objectives and Risks
**3.1 Objectives**
1. **Cookie hijacking**: Attackers can use XSS to steal users' cookies, which may contain sensitive information such as login credentials or session tokens.
2. **Web page tampering, phishing, and malicious propagation**: Attackers can use XSS to modify web page content, creating phishing schemes or spreading malicious links and software.
3. **Website redirection**: Attackers can use XSS to redirect users to other websites, potentially leading them to malicious sites or phishing pages.
4. **Obtaining user information**: Attackers can use XSS to access and collect users' personal information, such as email addresses, phone numbers, or other sensitive data.
**3.2 Risks**
1. **Propagation-related risks**: XSS attacks can lead to the spreading of malware, malicious links, or phishing schemes, which can result in further damage to users or systems.
2. **System security threats**: XSS attacks can pose threats to the security of both user devices and web applications, potentially leading to unauthorized access, data breaches, or other security incidents.
## **Part 3: Payload of XSS Attack**
In this section, we will analyze the Payload in the attack model. To understand Payload, we must understand encoding. To learn JavaScript well, we must also understand encoding. To truly excel in cybersecurity, mastering encoding is fundamental.
## 1. Encoding Basics
Although the encoding part is the most important and may be tedious, it is essential to master. Many transformed Payloads are built on your encoding foundation. Here, we will use a hexadecimal encoding tool to help you thoroughly learn encoding.
**1.1 Encoding Tools**
Hexadecimal viewer: Convenient for viewing the hexadecimal encoding of files.
MAC: Hex Friend
Windows: HxD
Editor Sublime: You can use Sublime to save files in different encoding types.
**1.2 ASCII**
- Definition:
American Standard Code for Information Interchange (ASCII) is a computer encoding system based on the Latin alphabet, mainly used for displaying modern English and other Western European languages.
- Encoding method:
ASCII is a single-byte encoding. It defines the encoding of 128 characters, occupying only the last 7 bits of a byte, with the first bit uniformly set to 0. Numbers 0 to 31 and 127 (a total of 33) are control characters or communication-specific characters. Numbers 32 to 126 (a total of 95) are characters (with 32 being a space).
**1.3 ISO-8859-1 (Latin1)**
- Definition:
Latin1 is an alias for ISO-8859-1. In addition to the characters included in ASCII, ISO-8859-1 also includes characters corresponding to Western European languages, Greek, Thai, Arabic, and Hebrew. The euro symbol appeared relatively late and was not included in ISO-8859-1.
- Encoding method:
ISO-8859-1 encoding is a single-byte encoding and is downward compatible with ASCII. Its encoding range is 0x00-0xFF, with 0x00-0x7F being identical to ASCII, 0x80-0x9F being control characters, and 0xA0-0xFF being text symbols.
- Note:
The character range represented by ISO-8859-1 encoding is very narrow and cannot represent Chinese characters. However, since it is a single-byte encoding and consistent with the most basic unit of computer representation, ISO-8859-1 encoding is still often used for representation. For example, although the two characters "中文" do not exist in ISO-8859-1 encoding, using GB2312 encoding as an example, they should be represented by the two characters "d6d0 cec4". When using ISO-8859-1 encoding, they are split into four bytes: "d6 d0 ce c4" (in fact, when storing, it is also processed in bytes). Therefore, Latin1 in MySQL can represent characters of any encoding.
- The relationship between Latin1 and ASCII encoding:
Latin1 is fully compatible with ASCII.
**1.4 Unicode encoding (UCS-2)**
**Code Point**: Code point, simply understood as the digital representation of characters. A character set can generally be represented by one or more two-dimensional tables composed of multiple rows and multiple columns. The points where rows and columns intersect in a two-dimensional table are called code points, and each code point is assigned a unique number, which is called code point value or code point number.
**BOM (Byte Order Mark)**: Byte order, which appears in the header of the file, indicates the order of bytes. The first byte is in front, which is "Big-Endian", and the second byte is in front. It is "Little-Endian".
There is a character called "ZERO WIDTH NO-BREAK SPACE" in the Unicode character set, and its code point is FEFF. And FFFE is a character that does not exist in Unicode, so it should not appear in actual transmission. Before transmitting the byte stream, we can pass the character "ZERO WIDTH NO-BREAK SPACE" to indicate the big and small end, so the character "ZERO WIDTH NO-BREAK SPACE" is also called BOM.
BOM can also be used to indicate the encoding method of text. Windows uses BOM to mark the encoding method of text files. It doesn't matter whether the file on the Mac has a BOM or not.
**For example**: \u00FF: 00 is the first byte, FF is the second byte. Like the code point representation, it belongs to the big-endian method.
**Unicode coded character set**: it aims to collect all characters in the world, and assign a unique character number to each character, that is, a code point (Code Point), which is represented by U+ followed by a hexadecimal number. All characters are divided into 17 planes (numbered 0-16) according to the frequency of use, that is, the basic multilingual plane and the supplementary plane. The basic multilingual plane, also known as plane 0, collects the most widely used characters, code points from U+0000 to U+FFFF, and each plane has 216=65536 code points;
**Unicode encoding**: The characters in the Unicode character set can have many different encoding methods, such as UTF-8, UTF-16, UTF-32, compression conversion, etc. What we usually call Unicode encoding is UCS-2, which directly maps character numbers (same as code points in Unicode) to character encodings, that is, character numbers are character encodings, and there is no special encoding algorithm conversion in the middle. It is a fixed-length double-byte encoding: because our UCS-2 only includes this multilingual plane (U+0000 to U+FFFF).
**BOM of UCS-2**: big endian mode: FEFF. Little endian mode: FFFE.
The file is saved as UTF-16 BE with BOM, which is equivalent to the big endian mode of UCS-2. You can see that the hexadecimal system starts with FEFF
**The relationship between Latin1 and Unicode encoding**: Latin1 corresponds to the first 256 code points of Unicode.
**1.5 UTF-16**
- Definition and encoding: UTF-16 is one of the usage methods of Unicode. Characters defined in the Unicode Basic Multilingual Plane (whether they are Latin letters, Chinese characters or other characters or symbols) are stored in 2 bytes. Characters defined in the auxiliary plane are stored as two 2-byte values in the form of a surrogate pair. is a double-byte encoding.
- The relationship between UTF-16 and UCS-2: UTF-16 can be regarded as the superset of UCS-2. Before there are no auxiliary plane characters (surrogate code points), UTF-16 and UCS-2 refer to the same meaning. But when the auxiliary plane characters are introduced, it is called UTF-16. Now if some software claims to support UCS-2 encoding, it actually implies that it cannot support character sets exceeding 2bytes in UTF-16. For UCS codes less than 0x10000, UTF-16 encoding is equal to UCS codes.
- BOM of UTF-16: big-endian mode: FEFF. Little endian mode: FFFE.
**1.6 UTF-8**
- Definition and encoding: UTF-8 is the most widely used implementation of Unicode on the Internet. This is an encoding designed for transmission, and makes encoding borderless, so that characters from all cultures in the world can be displayed. One of the biggest features of UTF-8 is that it is a variable-length encoding method. It can use 1~4 bytes to represent a symbol, and the byte length varies according to different symbols. When the character is in the range of ASCII code, it is represented by one byte, and the encoding of one byte of ASCII character is reserved as it. Note that a Chinese character in unicode occupies 2 bytes, while a Chinese character in UTF-8 occupies 3 bytes). From unicode to utf-8 is not a direct correspondence, but needs some algorithms and rules to convert.
- BOM for UTF8: EFBBBF. There is no character sequence problem in UTF-8, but BOM can be used to indicate that this file is a UTF-8 file.
The file is saved as UTF-8 BE with BOM, you can see that the hexadecimal starts with EFBBBF
**1.7 GBK/GB2312**
**Definition and encoding**: GB2312 is the earliest version of Chinese character encoding that only contains 6763 Chinese characters. GB2312 only supports simplified characters and is incomplete, which is obviously not enough. GBK encoding is an extension of GB2312 encoding, fully compatible with GB2312 standard, supporting simplified and traditional characters, including all Chinese characters. GBK encoding adopts a single-double-byte encoding scheme. The single-byte is consistent with Latin1, and the double-byte is the Chinese character part. The encoding range: 8140-FEFE, excluding the xx7F code point, a total of 23940 code points.
**The relationship between GBK and Latin1**: The GBK single-byte coding area is consistent with the Latin1 coding.
**The relationship between GBK and Unicode**: GBK and Unicode character set encoding are different but compatible. For example, although the Unicode value of "Han" is different from GBK, assuming that Unicode is a040 and GBK is b030, they can be converted accordingly. The Unicode area of Chinese characters: 4E00-u9FA5.
**GBK and UTF-8**: GBK Chinese characters adopt double-byte encoding which is smaller than the three-byte encoding in UTF-8. But UTF-8 is more general. GBK and UTF-8 conversion: GBK —> Unicode —> UTF8
## 2. Coding in the front end
Once you have the coding foundation, you can get to know the coding in the front end, so that you can really understand the Payload. What I have here should be the most comprehensive summary.
**2.1 Base64**
Base64 can be used to encode binary byte sequence data into text composed of ASCII character sequences. When using, specify Base64 in the transfer encoding method. The characters used include 26 uppercase and lowercase Latin letters, 10 numbers, plus sign + and slash /, a total of 64 characters and the equal sign = are used as suffixes. So a total of 65 characters.
Put 3 bytes of data into a 24-bit buffer successively, and the byte that comes first occupies the high position. If the data is less than 3 bytes, the remaining bits in the buffer are filled with 0. Take out 6 bits each time and use Base64 characters as the encoded output of the original data. For encoding, if the length of the original data is not a multiple of 3 and there is 1 input data left, add 2 = after the encoding result; if there are 2 input data left, add 1 = after the encoding result. It can be seen that the Base64 encoded data is about 3/4 of the original data.
The standard Base64 is not suitable for direct transmission in the URL, because the URL encoder will change the / and + characters in the standard Base64 into a form like %XX, and these % symbols need to be converted when they are stored in the database , because the % sign is already used as a wildcard in ANSI SQL. To solve this problem, an improved Base64 encoding for URLs can be used, which does not pad the = sign at the end, and changes the + and / in the standard Base64 to - and _ respectively, thus eliminating the need for URL encoding and decoding The conversion required for storage with the database avoids the increase in the length of the encoded information in the process, and unifies the format of object identifiers in databases, forms, etc.
window.btoa/window.atob base64 encoding (binary to ascii) and decoding only supports Latin1 character set.
**2.2 JS escape characters**
The js character string contains some special escape characters starting with a backslash, which are used to represent non-printing characters, and characters for other purposes can also be escaped to represent unicode and Latin1 characters.
Note:
1. The newline character \n used in innerHTML will only display a space and will not break the line.
2. Any unicode character and Latin1 character can be represented by \n, \u and \x. Through this, you can encrypt js to ensure js security and carry out covert attacks.
Example:
**2.3 URL encoding**
RFC 1738 stipulates that "only letters and numbers [0-9a-zA-Z], some special symbols "$-_.+!*'()," [not including double quotation marks], and certain reserved words, can Can be used directly in a URL without encoding". Therefore, when the link contains Chinese or other non-compliant characters, it needs to be encoded. However, due to the large number of browser manufacturers, there are many ways to encode URLs. If the encoding is not processed uniformly, it will have a great impact on code development and garbled characters will appear.
- URL encoding rules: Convert the characters to be encoded to UTF-8 encoding, and then add % in front of each byte.
- JS provides us with three URL encoding methods for strings: escape, encodeURI, encodeURIComponent
- escape: Since escape has been suggested to give up, please don’t use it
- encodeURI: 82 characters that encodeURI does not encode: !#$&'()*+,/:;=?@-._~0-9a-zA-Z, it can be seen that the reserved characters in the url will not be modified Encoding, so it is suitable for url overall encoding
- encodeURIComponent: This is the most useful encoding function for us. There are 71 characters that encodeURIComponent does not encode: !, ', (,), *, -, ., _, ~, 0-9, az, AZ.
It can be seen that the reserved words in the url are encoded, so when the passed parameters
Including the reserved words (@, &, =) in these urls, they can be encoded and transmitted by this method
The decoding methods corresponding to these three methods: unescape, decodeURI, decodeURIComponent
**2.4 HTML character entities**
Reserved characters in HTML must be replaced with character entities. Only in this way can it be displayed as characters, otherwise it will be parsed as HTML.
**Character entity encoding rules**: escape character = &#+ascii code; = & entity name;
**Conversion method**:
**2.5 Page Encoding**
**Page encoding settings:**
<meta charset="UTF-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
**Script encoding settings:**
<script type="text/javascript" src="myscripts.js" charset="UTF-8"></script>
Note: If you want JS to be used normally in UTF-8 and GBK, you can escape characters in all strings containing Chinese in JS.
## 3. Payload classification
Now you can know the Payload, and I have to say that the classification of Payload here can help you know Payload very well. It also helps you better correspond to the execution point.
**3.1 Atomic Payload**
The lowest level Payload.
**javascript code snippet**
It can be directly executed in eval, setTimeout, setInterval, and can also form high-level Payload through HTML, etc.
**javascript: javascript pseudo-protocol**
Structure: javascript:+js code. It can be executed when the href attribute of the a tag is clicked and window.location.href is assigned.
**DATA URI protocol**
DATA URI structure: data:[][;base64], . The DATA URI data will become the executable Payload contained in the src attribute and object data attribute of the iframe.
**String escape variant javascript code snippet**
unicode or Latin-1 for character strings.
**3.2 Pure HTML Payload**
This Payload feature does not have executable JS, but there is a risk of spreading, and other sites can be injected into the attacked website.
**HTML fragment containing link jumps**
mainly spreading hazards
**3.3 HTML Fragment Payload Containing Atomic Payload**
**Script tag fragment**
The payload of the script tag fragment can introduce external JS or directly executable script. This kind of Payload generally cannot be executed by directly copying it to innerHTML, but it can be executed on IE. However, it can be executed through document.write.
Example:
HTML fragment containing event handling
For example: HTML fragments containing img's onerror, svg's onload, input's onfocus, etc. can all be turned into executable Payloads.
**HTML fragments containing executable JS attributes**
**1. javascript pseudo-protocol**
**2. DATA URI**
Example:
Here we only introduce the main Payload, and there are many uncommon Payloads.
## **Part 4: XSS Attack Model Analysis**
In this part, we analyze the execution point and injection point of XSS according to the vulnerability attack model. Analyzing these two points is actually the process of finding loopholes.
**1. XSS vulnerability execution point**
1. The page goes straight out of the Dom
2. Client jump link: location.href / location.replace() / location.assign()
3. Write the value to the page: innerHTML, document.write and various variants. Here, the HTML fragment carrying the executable Payload is mainly written.
4. Script dynamic execution: eval, setTimeout(), setInterval()
5. Unsafe attribute setting: setAttribute. Unsafe attributes have been seen before: href of a tag, src of iframe, data of object
6. HTML5 postMessage data from insecure domain.
7. Defective third-party libraries.
**2. XSS vulnerability injection point**
See where we can inject our payload
1. The server returns data
2. Data entered by the user
3. Link parameters: window.location object three attributes href, search, search
4. Client storage: cookie, localStorage, sessionStorage
5. Cross-domain calls: postMessage data, Referer, window.name
The above content basically includes all execution points and injection points. It is very helpful for everyone to attack and defend XSS vulnerabilities.
## **Part 5: XSS Attack Defense Strategy**
**1. Tencent's internal public security defense and emergency response**
1. Access public DOM XSS defense JS
2. Internal vulnerability scanning system scan
3. Tencent Security Emergency Response Center: Security workers can submit Tencent-related vulnerabilities through this platform and get rewards based on vulnerability ratings.
4. Emergency response system for major failures.
**2. Secure coding**
2.1 Enforce point defense method
2.2 Other security defense methods
- 1. Use httpOnly for cookies
- 2. Use Content Security Policy in HTTP Header
**3. Code review**
Summarize the XSS checklist for code self-test and inspection
**4. Tools to automatically detect XSS vulnerabilities**
It is time-consuming to manually detect XSS vulnerabilities. Can we write a set of automatic XSS detection tools? I actually know that the injection point, execution point, and Payload automation process are completely possible.
The difficulty of automatic XSS detection lies in the detection of DOM type XSS. Because the complexity of the front-end JS is high, including static code analysis and dynamic execution analysis are not easy.

1,886,568 | Understanding Broker Commissions and Fees | In the world of forex and CFD trading, understanding broker commissions and fees is crucial for... | 0 | 2024-06-13T06:39:09 | https://dev.to/georgewilliam4425/understanding-broker-commissions-and-fees-256b |
In the world of [forex](https://bit.ly/forex-trading-t4t) and [CFD trading](https://bit.ly/4bXk670), understanding broker commissions and fees is crucial for managing costs and maximizing profitability. Different brokers and trading platforms have various fee structures, which can significantly impact your overall trading performance. This article provides an in-depth look at the types of commissions and fees associated with trading in forex and CFD markets, and how to choose a broker platform that aligns with your trading strategy.
Types of Broker Commissions and Fees
1. Spreads
• The spread is the difference between the bid (buy) and ask (sell) prices of a currency pair or CFD. Brokers typically earn money through the spread, and it can be fixed or variable. In forex trading, tighter spreads are preferable as they lower the cost of [trading](https://bit.ly/forex-trading-T4t). Variable spreads can widen during periods of high volatility, while fixed spreads remain constant but might be higher than the variable ones in stable market conditions.
2. Commission Fees
• Some brokers charge a commission per trade in addition to the spread. This fee is usually a fixed amount per lot traded or a percentage of the trade value. Brokers that offer ECN (Electronic Communication Network) accounts typically use this fee structure, providing tighter spreads but charging a commission on each trade. This is common in both forex and CFD [markets](https://bit.ly/forex-markets-t4t-seo).
3. Swap Fees (Overnight Financing)
• Swap fees, also known as overnight financing or rollover fees, are charged when a position is held open overnight. This fee reflects the interest rate differential between the two currencies in a forex pair or the cost of holding a CFD position. Swap fees can be positive or negative depending on the direction of your trade and the interest rate differential.
4. Account Maintenance Fees
• Some brokers charge account maintenance fees, which can include inactivity fees for accounts that have not been used for a certain period. These fees are less common but can add up if you do not trade frequently.
5. Deposit and Withdrawal Fees
• Brokers may charge fees for depositing and withdrawing funds from your trading account. These fees vary depending on the payment method used, such as bank transfers, credit cards, or e-wallets. It’s important to check these fees as they can impact your overall cost of trading.
6. Platform Fees
• Some advanced trading platforms might charge a subscription fee for access to premium features or data feeds. While many brokers offer their [trading platforms](https://bit.ly/3VhMfhU) for free, others might charge for additional services or third-party platform integration.
Comparing Broker Fees
When choosing a [broker](https://bit.ly/3yW1XYx) for forex and CFD trading, it’s essential to compare the overall cost structure, including spreads, commissions, swap fees, and other potential charges. Here’s how you can effectively compare broker fees:

1,886,567 | Big O Notation | Big O Notation: Big O Notation describes the upper bound of an algorithm's runtime or space... | 0 | 2024-06-13T06:37:46 | https://dev.to/bpk45_0670a02e0f3a6839b3a/big-o-notation-3nnf | devchallenge, cschallenge, computerscience, beginners | **Big O Notation:** Big O Notation describes the upper bound of an algorithm's runtime or space requirements relative to input size (n). It compares algorithm efficiency by focusing on growth rates, ensuring scalability and optimal performance as input sizes increase.
Here's a brief pseudocode example to illustrate how Big O Notation might be used to compare two sorting algorithms, Bubble Sort and Merge Sort, based on their time complexities.
**Bubble Sort (O(n^2))**
```
function bubbleSort(array):
n = length(array)
for i from 0 to n-1:
for j from 0 to n-i-1:
if array[j] > array[j+1]:
swap(array[j], array[j+1])
return array
```
**Merge Sort (O(n log n))**
```
function mergeSort(array):
if length(array) <= 1:
return array
middle = length(array) / 2
leftHalf = array[0:middle]
rightHalf = array[middle:]
return merge(mergeSort(leftHalf), mergeSort(rightHalf))
function merge(left, right):
result = []
while left is not empty and right is not empty:
if left[0] <= right[0]:
append result with left[0]
remove first element from left
else:
append result with right[0]
remove first element from right
while left is not empty:
append result with left[0]
remove first element from left
while right is not empty:
append result with right[0]
remove first element from right
return result
```
**Comparison**
**Bubble Sort:** Nested loops result in O(n^2) time complexity, which means its performance degrades significantly as the input size increases.
**Merge Sort:** Divides the array into halves and merges sorted halves, resulting in O(n log n) time complexity, which is more efficient for larger inputs.
These examples clearly demonstrate how Big O notation helps in effectively understanding and comparing the efficiency of different algorithms. | bpk45_0670a02e0f3a6839b3a |
1,886,562 | Step-by-Step Guide for Web Scraping Using BeautifulSoup | Web scraping is an essential skill for gathering data from websites, especially when that data isn't... | 0 | 2024-06-13T06:32:47 | https://dev.to/ionegarza/step-by-step-guide-for-web-scraping-using-beautifulsoup-hcd | webscraping, scraping, bs4, beautifulsoup | Web scraping is an essential skill for gathering data from websites, especially when that data isn't available via a public API. In this guide, I'll walk you through the [process of scraping a website using Python and BeautifulSoup](https://write.as/victoria-collins/tips-for-web-scraping-using-beautifulsoup), a powerful library for parsing HTML and XML documents. This guide is designed for beginners, so I'll cover everything you need to know to scrape your first website.
## Step 1: Setting Up Your Environment
Before you can start scraping, you need to set up your Python environment. Here's how to get started:
**Install Python:** If you haven't already, download and install Python from the official website. Make sure to check the option to add Python to your PATH during installation.
**Install Required Libraries:** Open your terminal or command prompt and install BeautifulSoup and requests, another library that we'll use to make HTTP requests to websites.
```
pip install beautifulsoup4 requests
```
## Step 2: Understanding HTML Structure
To effectively scrape a website, you need to understand its HTML structure. HTML (HyperText Markup Language) is the standard language for creating web pages. Each element in an HTML document is represented by tags, which can contain attributes and nested elements.
Here’s a simple example of an HTML document:
```
<!DOCTYPE html>
<html>
<head>
<title>Example Page</title>
</head>
<body>
<h1>Welcome to the Example Page</h1>
<p>This is a paragraph.</p>
<div class="content">
<p class="info">More information here.</p>
<a href="https://example.com">Visit Example</a>
</div>
</body>
</html>
```
## Step 3: Making an HTTP Request
To scrape a website, you first need to make an HTTP request to retrieve the page's HTML. This is where the requests library comes in handy. Let's scrape a simple example page:
```
import requests
url = "https://example.com"
response = requests.get(url)
if response.status_code == 200:
print("Successfully fetched the webpage!")
else:
print("Failed to retrieve the webpage.")
```
## Step 4: Parsing HTML with BeautifulSoup
Once you have the HTML content, you can use BeautifulSoup to parse it. BeautifulSoup provides a variety of methods for navigating and searching the parse tree.
```
from bs4 import BeautifulSoup
soup = BeautifulSoup(response.content, "html.parser")
# Print the title of the page
print(soup.title.string)
```
## Step 5: Navigating the Parse Tree
BeautifulSoup allows you to navigate the HTML parse tree using tags, attributes, and methods. Here are some basic ways to navigate:
- **Tag names**: Access elements by their tag names.
```
h1_tag = soup.h1
print(h1_tag.string)
```
- **Attributes**: Access elements using their attributes.
```
div_content = soup.find("div", class_="content")
print(div_content.p.string)
```
- **Methods**: Use methods like find(), find_all(), select(), and select_one() to locate elements.
```
info_paragraph = soup.find("p", class_="info")
print(info_paragraph.string)
```
## Step 6: Extracting Links
Extracting links from a webpage is a common task in web scraping. You can use the [find_all() method](https://medium.com/@spaw.co/beautifulsoup-find-all-421385b341d4) to locate all a tags and then extract the href attribute.
```
links = soup.find_all("a")
for link in links:
print(link.get("href"))
```
## Step 7: Handling Dynamic Content
Some websites use JavaScript to load content dynamically, which can complicate scraping. If you encounter such a site, you might need to use tools like Selenium to automate a browser and execute JavaScript.
## Step 8: Saving Data
Once you've extracted the data you need, you might want to save it to a file for further analysis. You can use Python's built-in csv module to save data to a CSV file.
```
import csv
data = [
["Title", "Link"],
["Example Page", "https://example.com"]
]
with open("data.csv", "w", newline="") as file:
writer = csv.writer(file)
writer.writerows(data)
```
## Step 9: Putting It All Together
Let’s combine everything we’ve learned into a single script that scrapes the example page, extracts the title and links, and saves them to a CSV file.
```
import requests
from bs4 import BeautifulSoup
import csv
# Step 1: Fetch the webpage
url = "https://example.com"
response = requests.get(url)
# Step 2: Parse the HTML
soup = BeautifulSoup(response.content, "html.parser")
# Step 3: Extract data
title = soup.title.string
links = soup.find_all("a")
# Step 4: Save data
data = [["Title", "Link"]]
for link in links:
data.append([title, link.get("href")])
with open("data.csv", "w", newline="") as file:
writer = csv.writer(file)
writer.writerows(data)
print("Data saved to data.csv")
```
## Step 10: Dealing with Common Issues
When scraping websites, you might encounter various issues, such as:
- **IP Blocking**: Websites may block your IP if they detect excessive requests. To avoid this, use rotating proxies or limit the frequency of your requests.
- **CAPTCHAs**: Some sites use [CAPTCHAs](https://www.purevpn.com/blog/types-of-captchas/) to prevent automated access. Solving CAPTCHAs programmatically can be challenging and may require third-party services.
- **Legal Concerns**: Always check the website's robots.txt file and terms of service to ensure you're allowed to scrape their data.
## Step 11: Best Practices
To make your web scraping more efficient and ethical, follow these best practices:
- **Respect Robots.txt**: Always respect the rules set in the robots.txt file of the website.
- **Polite Scraping**: Avoid making too many requests in a short period. Implement delays between requests.
- **User Agent**: Use a realistic user agent string to avoid being blocked by the website.
```
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36"
}
response = requests.get(url, headers=headers)
```
## Conclusion
Web scraping is a powerful tool for extracting data from websites. With Python and BeautifulSoup, you can scrape data from almost any webpage. By following this step-by-step guide, you now have the foundation to start your web scraping journey. Remember to always respect the website's terms of service and ethical guidelines while scraping. Happy scraping!

Tailwind... | 0 | 2024-06-13T06:27:54 | https://www.swhabitation.com/blogs/tailwind-css-vs-shadcn-which-should-you-choose-for-your-next-project | tailwindcss, shadcnui, frontend, webdev | If you're new to web development, you may be unsure of the best tools for website styling. Tailwind CSS and Shadcn are two well-liked options. They both assist you in creating stunning websites, but their functions are distinct. Let's examine what each one has to offer in more detail so you can decide which would work best for your project.
## What Is Tailwind CSS?
[Tailwind](https://tailwindcss.com/) is a CSS framework that prioritizes utility.
However, what does **"utility-first"** really mean? To put it simply, Tailwind offers compact, reusable classes that you can mix and match to create your own designs.
Use Tailwind's default classes for each element rather than creating unique CSS for each one.
Here's an example of styling a button with Tailwind CSS:
```
<button class="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
Click Me
</button>
```
The background color in this example is set by **bg-blue-500**, the text color, padding, and border radius are handled by different classes, and the background color changes as the button is hovered over.
## Why Choose Tailwind CSS?
- **Customization:** Tailwind offers a great degree of customisation. A configuration file makes it simple to alter the colors, spacing, and other styles.
- **Consistency:** You can guarantee a consistent design by employing the same utility classes across your project.
- **Efficiency**:Building designs quickly without creating bespoke CSS is made possible with Tailwind.
- **Responsive Design:** Designing with mobile devices in mind is made simple by Tailwind's integrated responsive design tools.
- **Community and Ecosystem** :Tailwind boasts a sizable community and a vast ecosystem that includes tools and plugins to improve your workflow.
## What Is Shadcn?
A component library called [Shadcn](https://ui.shadcn.com/) provides pre-made, usable components. Consider it as a toolbox full of interchangeable construction pieces that you can add to your project, such as buttons, cards, and modals.
Here's an example of how to utilise a Shadcn button component:
```
<Button variant="primary">
Click Me
</Button>
```
You don't have to worry about adding classes for hover effects, colors, or padding because this button is pre-styled. Shadcn takes care of everything.
## Why Choose Shadcn?
- **Speed:** Shadcn components save you time during development because they are ready to use right out of the box.
- **Consistency:** Because the components have preset styles, you can be guaranteed that your entire website will have the same appearance.
- **Ease of Use:** You don't have to be concerned with the specifics of styling. Utilize the parts exactly as they are.
- **Built-in Functionality:** Shadcn components frequently have built-in functionality, which minimizes the need for extra configuration or coding.
- **Design Best Practices:** Best practices were included in the design of the components, guaranteeing their responsiveness and accessibility.
## Key Differences
- **Customization:** Tailwind is more versatile than the other since it lets you specify your design scheme, even if both are customisable. Although Shadcn components are customisable, they have a pre-established structure.
- **Learning Curve:** You must become familiar with Tailwind's class names and structure. If you would rather use pre-styled components without getting into the nitty-gritty of CSS, Shadcn is simpler to learn.
- **Scalability:** For large projects where design consistency and maintainability are critical, Tailwind's methodology may be more scalable. Shadcn works well for short-term projects and rapid prototypes where efficiency is crucial.
- **Performance:** Tailwind's JIT (Just-In-Time) mode, which only creates the styles that are required, optimises performance. Performance may be impacted by Shadcn's pre-built components having more styles than you require.
## Which Should You Choose?
**Use Tailwind CSS if :**
- Desire total authority over your design.
- Take pleasure in creating parts from scratch.
- A highly adaptable design system is required.
- You're employed on a sizable project that calls for styles that are maintainable and scalable.
- You want to use as little CSS as possible to ensure peak performance.
**Use Shadcn if:**
- In order to expedite development, you favor ready-to-use components.
- You want to put in as little work as possible to retain design consistency.
- You should avoid devoting effort to intricate style.
- You're developing a prototype or a small-to medium-sized project.
- You respect best practices in design and integrated functionality.
## Conclusion
Shadcn and Tailwind CSS are both excellent tools, but they serve different purposes. Tailwind CSS is the perfect option if you enjoy having complete control and creating unique designs. Shadcn will save you time and effort if you like the ease of pre-made components that look fantastic right out of the package. When making your decision, take your project's requirements and personal tastes into account.

1,886,557 | Commodity Futures R-Breaker Strategy | Summary The R-Breaker strategy was developed by Richard Saidenberg and published in 1994.... | 0 | 2024-06-13T06:25:56 | https://dev.to/fmzquant/commodity-futures-r-breaker-strategy-4cc2 | strategy, fmzquant, futures, commodity | ## Summary
The R-Breaker strategy was developed by Richard Saidenberg and published in 1994. It was selected as one of the top ten most profitable trading strategies by "Futures Truth" magazine in the United States for 15 consecutive years. Compared with other strategies, R-Breaker is a trading strategy that combines trend and trend-reversal. Not only can the trend market be captured to obtain large profits, but also when the market trend reverses, it can take the initiative to take profit and to track the trend reverse.
## Resistance and support
Simply put, the R-Breaker strategy is a price support and resistance strategy. It calculates seven prices based on yesterday's highest, lowest and closing prices: a central price (pivot) and three support levels (s1 s2, s3), three resistance levels (r1, r2, r3). Then according to the positional relationship between the current price and these support and resistance levels, to form the trigger conditions for buying and selling, and through a certain algorithm adjustment, adjust the distance between these seven prices, further change the trigger value of the transaction.
- Break through buying price (resistance level r3) = yesterday’s highest price + 2 * (center price - yesterday’s lowest price) / 2
- Observing selling price (resistance level r2) = center price + (yesterday's highest price - yesterday's lowest price)
- Reverse selling price (resistance level r1) = 2 * Center price - yesterday's lowest price
- Central price (pivot) = (yesterday's highest price + yesterday's closing price + yesterday's lowest price) / 3
- Reverse buying price (support level s1) = 2 * Central price - yesterday's highest price
- Observing buying price (support level s2) = central price - (yesterday's highest price - yesterday's lowest price)
- Break through selling price (support level s3) = yesterday’s lowest price - 2 * (yesterday’s highest price - center price)
From this we can see that the R-Breaker strategy draws a grid-like price line based on yesterday's price, and updates these price lines once a day. In technical analysis, the support and resistance levels, and the role of the two can be converted to each other. When the price successfully breaks up the resistance level, the resistance level becomes the support level; when the price successfully breaks down the support level, the support level becomes the resistance level.
In actual trading, these support and resistance levels indicate to the trader the direction of opening and closing positions and the precise trading points. Traders with specific opening and closing conditions can flexibly customize according to intraday prices, central prices, resistance levels, and support levels, and can also manage positions based on these grid price lines.
## Strategy logic
Next, let us see how the R-Breaker strategy uses these support and resistance levels. Its logic is not complicated at all. If there is no holding position, enter the trend mode. When the price is greater than the break-through buying price, open long position; when the price is less than the break-through selling price, open short position.
- Trend mode
open long position: if there is no holding position and the price is greater than the breakthrough buying price
open short position: if there is no holding position and the price is less than the breakthrough selling price
close long position: if you holding a long position, and the highest price of the day is greater than the observing selling price, and the price is less than the reverse selling price
close short position: if you holding a short position, and the lowest price of the day is less than the observing buying price, and the price is greater than the reverse buying price
- Reverse mode
open long position: if you holding a short position, and the lowest price of the day is less than the observing buying price, and the price is greater than the reverse buying price
open short position: if you holding a long position, and the highest price of the day is greater than the observing selling price, and the price is less than the reverse selling price
close long position: if long positions are held and the price is less than the breakthrough selling price
close short position: if short position are held and the price is greater than the breakthrough buying price
If there are holding positions, it enters the reversal mode. When there are holding long positions, and the highest price on the day is greater than the observing selling price, and the price falls below the reverse selling price, the long position will be closed and the short position will be open synchronously. When holding short positions, and the lowest price of the day is less than the observing buying price, and the price breaks through the reverse buying price, the short position will be closed and long position will be open.

Parts coming up:
Part 3: Connect using a custom authorizer
Part 4: Topic Rules
## Connect using a presigned url
Similar to S3, it's possible to create a presigned url for IoT Core. You can even cache and reuse this presigned url for multiple clients as long as the client id is different per client. If you connect a client with a client id that is already in use, the other client will be disconnected. This can be a great method for pushing content to clients but also allows them to publish things themselves if your use case requires it. While this is a super easy method, it isn't the most flexible way of using it in terms of permissions. Please note that this only works for websocket urls, not for regular MQTT connections.
## Permissions
It's important to realize that the presigned url has the same permissions as the role that was used to sign it with. That means that _all clients will have the exact same permissions_ unless you specifically create and use a different role per use case. For example, if your Lambda has a role that allows connecting with any client ID on any topic, every client will be able to connect to any topic. In some cases this is totally fine but make sure this is OK for your use case. Obviously, you can (and you should) restrict your Lambda to only allow what you want your clients to do.
For instance, if you have a website where you want to be able to push live news updates to an end user, you can have a policy with this in it:
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:Connect",
"iot:Subscribe",
"iot:Receive"
],
"Resource": [
"arn:aws:iot:{region}:{account-id}:client/user-*",
"arn:aws:iot:{region}:{account-id}:topicfilter/news",
"arn:aws:iot:{region}:{account-id}:topic/news"
]
}
]
}
```
This will allow the client to connect with any client ID as long as it starts with _user-_ (you could generate a uuid to make it random), and will allow to subscribe to the "news" topic and receive messages over it. This is now basically a read only connect as the client isn't allowed to publish any messages with this policy.
You can have a separate role for your publishers that allows to write updates to the topic:
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"iot:Connect",
"iot:Publish"
],
"Resource": [
"arn:aws:iot:{region}:{account-id}:client/publisher-*",
"arn:aws:iot:{region}:{account-id}:topic/news"
]
}
]
}
```
Alternatively, you can of also [publish a message using the AWS SDK](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/client/iot-data-plane/command/PublishCommand/) instead of doing this with a client that is connected with MQTT. The _iot:Publish_ permission to the respective topic is still required obviously.
## Code
This seems to be quite hidden in the documentation however I did find some [example code](https://github.com/aws-samples/aws-iot-examples/blob/master/mqttSample/js/app.js). I converted this into something that makes use of the current AWS utilities which makes it a lot more compact and readable. The code examples are written in Typescript, I recommend using [Serverless Framework with esbuild](https://dev.to/slootjes/optimizing-typescript-packages-in-serverless-framework-with-esbuild-1ol4) to deploy the code so you can run it with a node runtime in Lambda.
```typescript
import * as crypto from 'node:crypto';
import { type BinaryLike } from 'node:crypto';
import { Sha256 } from '@aws-crypto/sha256-js';
import { type AwsCredentialIdentity } from '@aws-sdk/types';
import { SignatureV4 } from '@smithy/signature-v4';
const sha256 = (data: BinaryLike): string =>
crypto.createHash('sha256').update(data).digest().toString('hex');
const toQueryString = (queryStrings: Record<string, string>): string => Object.entries(queryStrings)
.map(([key, value]) => `${key}=${value}`)
.join('&');
export const getSignedUrl = async (
host: string,
region: string,
credentials: AwsCredentialIdentity,
expiresIn = 900,
): Promise<string> => {
const service = 'iotdevicegateway';
const algorithm = 'AWS4-HMAC-SHA256';
const sigV4 = new SignatureV4({
sha256: Sha256,
service,
region,
credentials,
});
const date = new Date().toISOString().replaceAll(/[:-]|\.\d{3}/gu, '');
const credentialScope = `${date.slice(0, 8)}/${region}/${service}/aws4_request`;
const parameters: Record<string, string> = {
'X-Amz-Algorithm': algorithm,
'X-Amz-Credential': `${encodeURIComponent(`${credentials.accessKeyId}/${credentialScope}`)}`,
'X-Amz-Date': date,
'X-Amz-Expires': expiresIn.toString(),
'X-Amz-SignedHeaders': 'host',
};
const path = '/mqtt';
const headers = `host:${host}\n`;
const canonicalRequest = `GET\n${path}\n${toQueryString(parameters)}\n${headers}\nhost\n${sha256('')}`;
const stringToSign = `${algorithm}\n${date}\n${credentialScope}\n${sha256(canonicalRequest)}`;
parameters['X-Amz-Signature'] = await sigV4.sign(stringToSign);
if (credentials.sessionToken) {
parameters['X-Amz-Security-Token'] = encodeURIComponent(credentials.sessionToken);
}
return `wss://${host}${path}?${toQueryString(parameters)}`;
};
```
I can now create a Lambda with the following code:
```typescript
import { type APIGatewayProxyResultV2 } from 'aws-lambda';
import { getSignedUrl } from '../../Service/IoTCore.js';
export const handle = async (): Promise<APIGatewayProxyResultV2> => ({
statusCode: 200,
body: JSON.stringify({
url: await getSignedUrl(process.env.AWS_IOT_HOST ?? '', process.env.AWS_DEFAULT_REGION ?? '', {
accessKeyId: process.env.AWS_ACCESS_KEY_ID ?? '',
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY ?? '',
sessionToken: process.env.AWS_SESSION_TOKEN ?? undefined,
}),
}),
});
```
and when calling it, I receive a URL I can use to connect with something like a Paho MQTT Client. For this example I've set a AWS_IOT_HOST environment variable with the endpoint of IoT Core (xxxxxxx-ats.iot.eu-west-1.amazonaws.com). The endpoint can be found by navigating to the IoT Core service in the dashboard and then going to Settings:
You can of course also use the [IoT Core SDK](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/client/iot/command/DescribeEndpointCommand/) to retrieve the endpoint.
# Connecting
Now that you have a way of getting a presigned url, you want to use it to connect to IoT Core. To do this from a browser, you can use the [Paho MQTT library](https://github.com/eclipse/paho.mqtt.javascript) and following snippet of code:
```javascript
const client = new Paho.MQTT.Client(url, clientId);
client.connect({
useSSL: true,
timeout: 3,
mqttVersion: 4,
onSuccess: function () {
console.log("connected");
},
onFailure: function () {
console.log("failed to connect");
},
});
client.onMessageArrived = function (message) {
console.log(message);
};
client.onConnectionLost = function (e) {
console.log("lost connection", e);
};
```
The url is the response from your Lambda. Make sure the clientId is allowed by your policy as otherwise it will refuse to connect.
You can subscribe to a topic like this:
```javascript
client.subscribe('updates/"');
```
and publish a message like this:
```javascript
const message = new Paho.MQTT.Message(payload);
message.destinationName = 'updates/messages';
client.send(message);
```
Please note, once again, doing anything not allowed by your policy will result in a disconnect.
# Caching
Presigned urls from a Lambda only work for a limited time due to how IAM works but it's possible to cache it in a CDN like CloudFront for a couple of minutes. This way you do not need to generate a fresh url for every visitor. With my configuration, the presigned urls are valid for a maximum of 5 minutes. In practice, I cache them for 1 minute to be on the very safe side.
# Summary
You now have a basic way of working with IoT Core that allows for powerful bidirectional communication. Have fun!
In part 3 I will explain how a custom authorizer can be used to do more fine grained permissions per client. | slootjes |

This time, I landed on the __concept of symbols in JavaScript__, which is something I don't have to deal with at work, but something that JavaScript offers and it'd be nice to understand what it is and why it is :D
## What is a Symbol?
__A symbol is a unique and immutable data type in JavaScript__.
If that doesn't tell you anything (which indeed didn't for me), know that a symbol is one of the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#primitive_values" target="_blank">JavaScript primitive data types</a> just as string, boolean, integer etc. but it works like a *special identifier to access object properties*, and it can be used more or less like a property key.
Let's imagine that we have an object where we store a person's `name`, an `id` and their `age`.
```javascript
let person = {
name: "Sophia",
id: 12345678,
age: 24, // (yes, I'm a trailing comma person)
};
```
If we want to access the value of the `id` property, we'd just do:
```javascript
console.log(person.id); // will give us 12345678
```
It is fair to assume that `id` won't change as often as the other characteristics of a person, and tailor our work around that assumption.
Let's try to use a symbol as a key by creating it. This can be done using the `Symbol()` constructor:
```javascript
let symbolIDKey = Symbol("id");
let person = {
name: "Sophia",
[symbolIDKey]: 12345678,
age: 30,
};
console.log(person[symbolIDKey]); // outputs 12345678
```
You could, in theory, use no `"id"` parameter (properly referred as __descriptor__), but if you were to use more than one symbol key, it'd be more challenging to know which is which.
## Why symbols then?
Using symbols as object keys will provide you with a unique and guaranteed way of accessing object properties, __even if other code adds or modifies properties with the same key__.
For example:
```javascript
let symbolIDKey = Symbol("id");
let person = {
name: "Sophia",
[symbolIDKey] = 12345678,
age: 30,
};
```
Some other code, for whatever reason, will try to do
```javascript
person.id = 00000000;
```
You will be left with
```javascript
let symbolIDKey = Symbol("id");
let person = {
name: "Sophia",
[symbolIDKey] = 12345678,
age: 30,
id: 00000000,
};
console.log(person.id); // will output 00000000
console.log(person[symbolIDKey]); // will output our more expected 12345678
```
The symbol key is allowing us to preserve the original value even if some other code might try to alter the property `id`.
> With symbols you can add private properties to an object that are not intended to be modified or accessed directly by other code.
But beware! Symbols keys are not enumerated, which means that __they do not show up in the list of keys of the object__ if you try to access them by loops and mappings.
You cannot even access the symbol keys of an object with <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys" target="_blank" rel="norefferer noopener">`keys()`</a> nor with <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertyNames" target="_blank" rel="norefferer noopener">`getOwnPropertyNames()`</a>!
You will need to be aware of the structure of your object and if you need to access the symbol keys, you'll have to use <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/getOwnPropertySymbols" target="_blank" rel="norefferer noopener">`getOwnPropertySymbols()`</a>.
...
And that's it! I don't see myself using this approach anytime soon, but it's good to know that, should I be concerned with the integrity of the data I work with, there are ways for me to preserve some information in the flimsy world that JavaScript often creates for us.

1,886,523 | Do Unit Tests Find Bugs? | I've been writing software for over 20 years and don't believe unit tests find bugs. Yet, I wouldn't... | 25,505 | 2024-06-13T05:52:06 | https://www.growingdev.net/p/do-unit-tests-find-bugs | I've been writing software for over 20 years and don't believe unit tests find bugs.
Yet, I wouldn't want to work in a code base without unit tests.
## Why unit tests don't find bugs?
To understand why unit tests don't find bugs, we can look at how they are created. Here are the three main ways to handle unit tests:
- developers write the tests along with writing the code
- Test Driven Development (TDD)
- unit tests are considered a waste of time, so they don't exist
When the same software developer writes unit tests and code simultaneously, the tests tend to reflect closely what the code does. Both tests and code follow the same logic, stemming from the same understanding of the problem. As a result, the tests won't find major implementation issues. If they find small typos or bugs, it's usually only by chance.
Test-driven development calls for writing unit tests before implementing product changes. Because no product code exists, the unit tests are expected to fail initially or even not compile. The goal is to write product code to make the tests pass. In TDD, new unit tests are added mostly to drive the implementation of new scenarios. An unsupported scenario could be considered a bug, but it's far-fetched. As a result, TDD rarely finds existing bugs.
If unit tests don't exist, they cannot find any bugs.
## If unit tests don't find bugs, why do we write them?
While unit tests are not great at finding bugs, they are extremely effective at preventing new ones. Unit tests pin the program's behavior. Any change that visibly modifies this behavior should make the tests fail. The developer whose changes caused the failures should examine them and either fix the tests—if the change in the behavior was intentional—or fix the code. Many test failures indicate assumptions that the developer unknowingly broke. Without tests, they would turn into customer-impacting bugs.
Other important advantages of unit tests include:
- Documentation - comprehensive unit tests can serve as product specification
- More modular and maintainable code - writing unit tests for tightly coupled code is difficult. Unit tests drive writing more modular and loosely coupled code because it is much easier to test.
- Automated testing - unit tests are much faster to run and more comprehensive than testing changes manually.
## If unit tests don't find bugs, what does?
There are many ways to find bugs in the code. Integration testing, fuzz testing, and stress testing are just some examples. However, the three below are my favorite because they require little to no additional effort from the developers:
- Exploratory testing: Try using the product you're working on. See what happens if you combine a few features or try less common scenarios.
- Code reviews: One weakness of unit tests is that they are implemented with the same perspective as the code. Code reviews offer the ability to look at the change from a different angle, which often leads to discovering issues.
- Paying attention: Whenever you code, debug, or troubleshoot an issue, have your eyes open. Many bugs are hiding in plain sight. Carefully reading error messages, logs, or stack traces can lead to identifying serious problems.

1,886,518 | How Quick Fix Urine Passes a Lab Test | Do you have a co-worker or a classmate who always passes their lab tests even though they are a... | 0 | 2024-06-13T05:39:09 | https://dev.to/elite_jhon/how-quick-fix-urine-1f1 |
Do you have a co-worker or a classmate who always passes their lab tests even though they are a recreational substance user? They found the secret. It is known as [Quick Fix](https://www.quickfixsynthetic.com/) synthetic urine.
If you suspect an impromptu lab test is coming up, you need to know that drinking water, cranberry juice, or any other beverages will not erase the presence of recreational substances in your urine overnight. Order your quick-fix fake pee kit in advance and confidently pass any random lab test that comes your way.
How does a Quick Fix help you pass a lab test? The answer lies in the science and ingredients. Here are the 4 most important components and how they work together for drug testing.
**Quick Fix Is Purely Based on Science**
Quick Fix urine was created by Spectrum Labs 23 years ago. The main reason? To aid people who desperately need to pass a lab test. To keep up with technology, Quick Fix employs a team of expert scientists and engineers who work round the clock to create high-quality synthetic urine.
This ensures that no red flags are raised during testing and you can comfortably keep your job as you work towards addiction control.
To make the pee smell and appear like real urine, the scientists hired by Quick Fix put in a lot of effort to recreate the chemical composition of actual urine. By conducting extensive research, they also guarantee that the highest quality criteria are attained to produce a waterproof solution that is unrivaled in quality and efficacy.
Before quick-fix urine is released into the market, it must go through extensive testing. This ensures effectiveness. Quick-fix technicians and scientists will test their products against all known drug tests and verify a negative result before releasing it into the market. Doing this guarantees you that you can use the product with confidence.
**Creatinine**
Creatinine is one of the most analyzed components during lab testing. It is a reliable indicator of overall kidney function.
The reason why many people fail lab tests is because they attempt to consume excessive water just before a urine test.
The water can lower the metabolites in the urine but will not flush them out entirely.
Some individuals add water to their urine samples. When the sample is overly diluted, the creatinine levels will fall below the normal range. Once the lab technician finds abnormally low creatinine levels in your urine sample, they will report that it has been tampered with and you will fail your lab test.
If the dreaded lab test is looming and you have not been abstaining from substance use but you need to keep your job, order your Quick Fix today and exhale. This is because the synthetic creatinine levels in the quick-fix sample are the same as the original sample. The correct creatinine levels will give the desired results and avoid suspicion.
**Realistic PH. Range**
[According to the American Association for Clinical Chemistry](https://www.webmd.com/a-to-z-guides/what-to-know-about-a-urine-ph-test),the PH range for a normal human being is between 4.8 and 8. PH that is under 6 is acidic and if it goes way above 8, it is alkaline.
If you attempt to mask the presence of metabolites in your urine by adding substances such as warm water or apple cider vinegar, the specimen PH will go outside the normal range and you will get caught. Quick-fix samples are consistent with human urine. The balanced PH enhances its believability and validates the sample's authenticity.
**The Temperature**
Drug tests at the workplace have high stakes and everyone will do whatever it takes to pass. Did you know that you can buy a Quick Fix, carefully conceal it for the test, and still fail a urine lab test because of the temperature? If you hand over your urine specimen and the temperature range is outside the range of 90 to 100°F your sample will be considered suspicious. It could mean that you have adulterated, diluted, or substituted the sample with something else.

<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Now, what do I mean by that?<o:p></o:p></span></p>
<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span lang="EN-US" style="font-size: 14.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Problems: Front-end keeps changing <o:p></o:p></span></b></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">You see, front-end technologies keep changing all the time. So, when you focus only on the front-end, you will face a lot of difficulties in the upcoming years. Here are several reasons why.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Let’s take a scenario. Let’s say you are an Angular developer who has worked in a company for several years. And you haven't invested enough time building good applications from start to finish, from the data layer to the middle-tier server-side APIs, how to containerize applications, how to construct proper software objects, and how to deploy applications in different types of environments.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Now, by the time you leave the company, you realize that the front-end landscape has changed a lot. And let’s say there are very limited positions for Angular developers. So, you are in a position to relearn another framework like React or Vue JS. And then you start looking for a new job. As you can see, this is a very dangerous position to exist in.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">This is what happens with front-end “focused” careers. So, things change a lot in UI. <o:p></o:p></span></p>
<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span lang="EN-US" style="font-size: 14.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Problems: Automation tools for front-end<o:p></o:p></span></b></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">The existence of several automation tools is another reason to stay away from the front end. You see, business owners and especially entrepreneurs are becoming more favorable to these types of tools to design User Interfaces that provide drag-and-drop functionalities. And this is just the beginning. These UI automation tools are becoming more and more advanced with modern features and robust ways to create UIs without the need to write a single line of code. In that case, where does that leave someone who has only worked on the front end? <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Having said that, what are the options when faced with a situation like this?<o:p></o:p></span></p>
<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span lang="EN-US" style="font-size: 14.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Solutions: Prepare yourself as a full-stack developer <o:p></o:p></span></b></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">To solve this issue, you need to be prepared as a full-stack developer. Usually, a full-stack developer makes a good application by having a wide range of knowledge. But what does that mean?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">A full-stack software developer typically knows the front end, back end, and servers but they're not front-end experts. They don't have to be. They just need to know a little bit of HTML, and CSS and be able to make API calls with JavaScript and kind of put the piping together. But they will be mostly working on the data layer, the business logic of the application, the middle tier, and the micro-services. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Also, be able to apply object-oriented principles, be able to make the codebase more extensible, make use of proper design principles, and know how to deploy the codebase in containerized environments. So this is critical knowledge, which includes the actual logic building of the application.<o:p></o:p></span></p>
<p class="MsoNormal"><b style="mso-bidi-font-weight: normal;"><span lang="EN-US" style="font-size: 14.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">Solutions: Learn long-lasting skills like Java, SQL, Python<o:p></o:p></span></b></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">So, I will recommend you focus on learning the skills which have a low-time preference. Skills like SQL, Java, Python, and Spring have existed for a long time and have proven to provide very stable careers that will last for more than 10 or 15 years</span><span lang="EN-US"> </span><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">I mean, Java has been around for almost 30 years now, maybe longer, Python has been around for even longer, and SQL has been around for nearly 50 years now. And these things don't change very often.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">And that’s my motto, to stick with these long-lasting skills that are important and skills that emphasize the fundamentals. The fundamental principles of good software construction, data modeling, and software design don't change that often. Those are the things you must focus on to become a solid software development professional!<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size: 12.0pt; mso-bidi-font-size: 11.0pt; line-height: 107%; font-family: 'Times New Roman',serif;">For a well-rounded career where you're constantly improving the skills you need to build a project from start to finish, you need to focus on the fundamentals.<o:p></o:p></span></p>

I hope you're all doing well! I wanted to share a story about something cool I was working on that took an unexpected turn.
I recently created a project called SearchFast. It's a search tool for macOS that works on both Intel and M series chips.
Using Next.js, Tauri, Rust, and OpenAI's GPT models, I aimed to make searching on macOS easy and smooth.
SearchFast ran quietly in the background and could be brought up with a simple
```
Cmd+J
```
shortcut.
It had a modern interface and smart searches that made finding information really quick. I was super proud of what I built and excited to share it.
But then, Apple announced new integrations with Cortana and ChatGPT that work across all apps.
It was pretty much what I had envisioned for SearchFast, built into macOS and supported by Apple.
While it’s a bit disappointing to see my idea overshadowed, I’m still excited about the advancements in technology.

It is not realistic to collect all the data from every market, after all, the amount of data is too large. For the digital currency market, FMZ platform supports limited backtest data for exchanges and trading pairs. If you want to backtest some exchanges and trading pairs that temporarily wasn't supported by FMZ platform, you can use a custom data source for backtest, but this premise requires that you have data. Therefore, there is an urgent need for a market quotes collection program, which can be persisted and best obtained in real time.
In this way, we can solve several needs, such as:
- Multiple robots can be provided with data sources, which can ease the frequency of each robot's access to the exchange interface.
- You can get K-line data with a sufficient number of K-line BARs when the robot starts, and you no longer have to worry about the insufficient number of K-line BARs when the robot starts.
- It can collect market data of rare currencies and provide a custom data source for the FMZ platform backtest system.
and many more..
We plan to use python to achieve this, why? Because it's very convenient
## Ready
- Python's pymongo library
Because you need to use database for persistent storage. The database selection uses MongoDB and the Python language is used to write the collection program, so the driver library of this database is required.
Just install pymongo on Python.
- Install MongoDB on the hosting device
For example: MacOS installs MongoDB, also same as windows system installs MongoDB. There are many tutorials online. Take the installation of MacOS system as an example:
- Download
Download link: https://www.mongodb.com/download-center?jmp=nav#community
- Unzip
After downloading, unzip to the directory: /usr/local
- Configure environment variables
Terminal input: open -e .bash_profile, after opening the file, write: exportPATH=${PATH}:/usr/local/MongoDB/bin
After saving, in the terminal, uses source .bash_profile to make the changes take effect.
- Manually configure the database file directory and log directory
Create the corresponding folder in the directory /usr/local/data/db.
Create the corresponding folder in the directory /usr/local/data/logs.
Edit the configuration file mongo.conf:
```
#bind_ip_all = true # Any computer can connect
bind_ip = 127.0.0.1 # Local computer can access
port = 27017 # The instance runs on port 27017 (default)
dbpath = /usr/local/data/db # data folder storage address (db need to be created in advance)
logpath = /usr/local/data/logs/mongodb.log # log file address
logappend = false # whether to add or rewrite the log file at startup
fork = false # Whether to run in the background
auth = false # Enable user verification
```
- Run MongoDB service
command:
```
./mongod -f mongo.conf
```
- Stop MongoDB service
```
use admin;
db.shutdownServer();
```
## Implement the collector program
The collector operates as a Python robot strategy on FMZ platform. I just implemented a simple example to show the ideas of this article.
Collector program code:
```
import pymongo
import json
def main():
Log("Test data collection")
# Connect to the database service
myDBClient = pymongo.MongoClient("mongodb://localhost:27017") # mongodb://127.0.0.1:27017
# Create a database
huobi_DB = myDBClient["huobi"]
# Print the current database table
collist = huobi_DB.list_collection_names()
Log("collist:", collist)
# Check if the table is deleted
arrDropNames = json.loads(dropNames)
if isinstance(arrDropNames, list):
for i in range(len(arrDropNames)):
dropName = arrDropNames[i]
if isinstance(dropName, str):
if not dropName in collist:
continue
tab = huobi_DB[dropName]
Log("dropName:", dropName, "delete:", dropName)
ret = tab.drop()
collist = huobi_DB.list_collection_names()
if dropName in collist:
Log(dropName, "failed to delete")
else :
Log(dropName, "successfully deleted")
# Create the records table
huobi_DB_Records = huobi_DB["records"]
# Request data
preBarTime = 0
index = 1
while True:
r = _C(exchange.GetRecords)
if len(r) < 2:
Sleep(1000)
continue
if preBarTime == 0:
# Write all BAR data for the first time
for i in range(len(r) - 1):
# Write one by one
bar = r[i]
huobi_DB_Records.insert_one({"index": index, "High": bar["High"], "Low": bar["Low"], "Open": bar["Open"], "Close": bar["Close"], "Time": bar["Time"], "Volume": bar["Volume"]})
index += 1
preBarTime = r[-1]["Time"]
elif preBarTime != r[-1]["Time"]:
bar = r[-2]
huobi_DB_Records.insert_one({"index": index, "High": bar["High"], "Low": bar["Low"], "Open": bar["Open"], "Close": bar["Close"], "Time": bar["Time"], "Volume": bar["Volume"]})
index += 1
preBarTime = r[-1]["Time"]
LogStatus(_D(), "preBarTime:", preBarTime, "_D(preBarTime):", _D(preBarTime/1000), "index:", index)
Sleep(10000)
```
Full strategy address: https://www.fmz.com/strategy/199120
## Usage data
Create a strategy robot that uses data.
Note: You need to check the "python PlotLine Template", if you don't have it, you can copy one from the strategy square to your strategy library.
Here is the address: https://www.fmz.com/strategy/39066
```
import pymongo
import json
def main():
Log("Test using database data")
# Connect to the database service
myDBClient = pymongo.MongoClient("mongodb://localhost:27017") # mongodb://127.0.0.1:27017
# Create a database
huobi_DB = myDBClient["huobi"]
# Print the current database table
collist = huobi_DB.list_collection_names()
Log("collist:", collist)
# Query data printing
huobi_DB_Records = huobi_DB["records"]
while True:
arrRecords = []
for x in huobi_DB_Records.find():
bar = {
"High": x["High"],
"Low": x["Low"],
"Close": x["Close"],
"Open": x["Open"],
"Time": x["Time"],
"Volume": x["Volume"]
}
arrRecords.append(bar)
# Use the line drawing library to draw the obtained K-line data
ext.PlotRecords(arrRecords, "K")
LogStatus(_D(), "records length:", len(arrRecords))
Sleep(10000)
```
It can be seen that the strategy robot code that uses the data does not access any exchange interface. The data is obtained by accessing the database. The market collector program does not record the current BAR data. It collects the K-line BAR in the completed state. If the current BAR real-time data is needed, it can be modified slightly.
The current example code is just for demonstration. When accessing the data records in the table in the database, all are obtained. In this way, as the time for collecting data increases, more and more data is collected. All queries will affect performance to a certain extent, and can be designed. Only data that is newer than the current data is queried and added to the current data.
## Run
Running docker program
On the device where the docker is located, run the MongoDB database service
The collector runs to collect the BTC_USDT trading pairs of FMZ Platform WexApp simulation exchange marekt quotes:
WexApp Address: https://wex.app/trade?currency=BTC_USDT
Robot A using database data:
Robot B using database data:
WexApp page:
As you can see in the figure, robots with different IDs share K-line data using one data source.
## Collect K-line data of any period
Relying on the powerful functions of FMZ platform, we can easily collect K-line data at any cycle.
For example, I want to collect a 3-minute K-line, what if the exchange does not have a 3-minute K-line? It does not matter, it can be easily achieved.
We modify the configuration of the collector robot, the K line period is set to 3 minutes, and FMZ platform will automatically synthesize a 3 minute K line to the collector program.
We use the parameter to delete the name of the table, setting: ["records"] delete the 1 minute K-line data table collected before. Prepare to collect 3-minute K-line data.
Start the collector program, and then re-start the strategy robot using the data.
You can see the K-line chart drawn, the interval between BARs is 3 minutes, and each BAR is a K-line bar with a 3-minute period.
In the next issue, we will try to implement the requirements of custom data sources.

1,886,505 | Where do VDI costs hide? - A detailed TCO breakdown | Where do VDI costs hide? - A detailed TCO breakdown What is TCO? Total Cost of... | 0 | 2024-06-13T05:09:43 | https://dev.to/struthi/where-do-vdi-costs-hide-a-detailed-tco-breakdown-5b7d | vdi, virtualization, containers, devops | # Where do VDI costs hide? - A detailed TCO breakdown
## What is TCO?
Total Cost of Ownership (TCO) is a critical metric used to evaluate the overall cost efficiency of software purchases. For IT teams, managing hardware tools for a distributed workforce can be costly. Virtual desktop infrastructure (VDI) offers a solution by providing remote-friendly, secure, and flexible work environments. This guide breaks down the components of TCO and provides actionable insights for optimizing VDI deployments.
TCO is used argumentatively in several business decisions to get a single-number view of how profitable or advantageous a certain software purchase can be for the problem they are trying to solve.
The intricacies of TCO are often vague and vary on several external and internal factors which need to be accounted for, to give a realistic and definitive view on the matter.
In this blog, we provide a comprehensive guide to understanding and defining your TCO for your most convenient alternatives while deciding your next VDI and where differentiated engineering can help with your cost efficiencies.
## Phases of TCO
To arrive at a more factual narrative of your total cost of ownership with respect to virtual desktops, it helps to see the cost split across phases of deployment, owing to their uneven distribution.
The three phases of your average VDI deployment include Upfront CapEx, Deployment OpEx, and Ongoing OpEx.
> CapEx (capital expenditure) represents a significant initial investment in assets that will provide benefits over multiple years. CapEx is capitalized on the balance sheet and expensed through depreciation over the asset's useful life.
> OpEx (operating expenditure) refers to the ongoing costs incurred by a company for running its day-to-day operations. Unlike capital expenditures (CapEx), operating expenses are fully tax-deductible for the year in which they are incurred. OpEx is recorded on the income statement as an expense for the accounting period.
Introducing Neverinstall as an alternative to Citrix and VMWare offers a 60% higher cost-efficiency that enhances performance without sacrificing quality. Its modern architecture eliminates unnecessary components, improves latency, and ensures stable connections even at very low internet speeds, as we shall discover with a thorough analysis of the expenses through the first three years of use. By delivering substantial cost savings across setup, operational, and maintenance expenses, Neverinstall emerges as the most economical choice with its own performance edges.
## Upfront CapEx
To establish a functional VDI environment and deliver virtual desktops, organizations must invest in the following critical components if they choose a traditional solution like Citrix or VMWare:
- Load balancer and VPN gateway for secure and efficient traffic management.
- Broker software for managing and provisioning virtual desktops.
- Microsoft Windows Server operating systems and SQL databases for backend infrastructure.
- Portal/enterprise storefront software for providing a user-friendly interface to access virtual desktops.
- Specialized IT Labor involved in configuration and monitoring software for managing and monitoring the VDI environment.
- Image management software for creating, updating, and deploying virtual desktop images. (Usually defers to applications like FSLogix)
- VDI licenses for the virtual desktop software.
- Hypervisor host licenses for the virtualization platform.
- Server and storage hardware for hosting the virtual desktops and storing data.
- Storage management software for efficient storage utilization and management.
The most consequential decision here relies on the hardware choice you intend to make for your organizational goals.
Based on the assumed usage and setup for a 100-user environment requiring an on-premises deployment, the following numbers have been calculated for the most popular options: [Citrix](https://docs.citrix.com), [VMware](https://www.vmware.com), and Neverinstall. Other alternatives in 2024 include [Parallels](https://www.parallels.com), [Nutanix](https://www.nutanix.com), Proxmox, and [Workspot](https://www.workspot.com), among a few others.
### Total Cost of Ownership (TCO)
Your [TCO calculation](https://cdn2.hubspot.net) should account for all these factors over a typical lifecycle of the hardware (often considered to be 3 years for such calculations):
- Initial purchase costs (hardware + auxiliary)
- Annual operating costs (maintenance + energy)
- Replacement costs at the end of the life cycle.
## Choice of Hardware
### Thin Clients vs. Full Desktops
Thin clients are generally favored for VDI/DaaS deployments due to their lower cost and minimal local processing requirements. Here’s a rough breakdown of the initial hardware costs:
- Thin Clients: ranges from $170 to $316 per device
- Full Desktops: Up to $500 per device
### Auxiliary Hardware Costs
Initial expenses on auxiliary hardware (antivirus software, mice, speakers, etc.) total approximately $4,200 in the first year for setting up 100 workspaces at $42/user.
### Operating Costs
- Maintenance Costs: This includes the IT labor and the hardware replacements that go into setting up, deploying, configuring and maintenance through the year.
- Energy Consumption: There's a significant difference in power consumption costs between your hardware options. Assume cost per KWHr to be around $0.17, taken as a global average.
- Desktops: Approximately $2,543.20 per year for 149.6 KWHr
- Thin Clients: Approximately $329.12 per year for 19.36 KWHr
- This stark contrast highlights the efficiency of thin clients in long-term energy expenditure.
### Replacement Costs
Desktop replacement costs are 876% higher than those for thin clients. This substantial difference should be factored into the long-term financial planning and TCO as well.
## Deployment & Ongoing OpEx
### Licensing Options
When setting up a virtual desktop infrastructure (VDI), one of the significant upfront costs is software and hardware licenses. However, careful planning can help streamline these expenses. The choice between Windows or Linux operating systems depends on your use case. Linux, being open-source, is a cost-effective option for scenarios like supermarkets or retail environments. However, [Windows licenses](https://www.microsoft.com) may be preferred if your applications or users require Microsoft-specific technologies or familiarity.
> VMware and Citrix solutions require you to purchase the VDA license, which can be optimized by going for the 3-year subscriptions. Neverinstall allows you to opt for the Windows E3 or E5 option without the RDS Cal license.
### VDI License
Citrix license stands comparatively higher at $25/user/month while VMware and Neverinstall have a comparable rate at $5-$20 with different tiers. It's a monthly cost and can be altered according to your compute needs.
Understand more about Neverinstall's modernized VDI architecture [here](https://blog.neverinstall.com), to thoroughly explore the specifics.
### Storage Costs
To calculate the annual storage costs for 100 users with 128GB/user, we need to find the total storage requirement and then estimate the costs based on typical storage pricing.
Given:
- Number of users: 100, 150 and 225 assuming a 50% growth in headcount every year.
- Storage per user: 128GB (0.128TB)
The annual storage costs will depend on the type of storage solution you choose (e.g., SDD, HDD, etc.) and the associated pricing model.
For example, if you opt for [cloud storage at a rate of $0.02 per GB per month](https://www.techradar.com), the annual costs would be:
100 users × 0.128TB/users × 1024GB/TB × $0.02/GB × 12 months = $3,146
and so on for 150 and 225 users in the next few years.
### Energy Costs
The energy consumption for average usage of 22 days a month, 8 hours a day, at $0.17/KWHr, not considering perpetually running machines, results in a cost of $50,261 in the first year.
In contrast, for Neverinstall, the cost runs up to $25,295 due to the optimized logic associated with their servers and backend.
### Labor Costs
On average between highly and moderately skilled IT technicians required to run your IT set up, the cost per hour is considered to be $40.
## Calculating TCO for Citrix, VMware & Neverinstall
### Initial Setup Costs
- Neverinstall offers up to 72% savings on desktop provisioning hardware and setup costs compared to Citrix and up to 66% savings compared to VMware.
- Neverinstall provides up to 40% savings on hypervisor setup and hardware costs compared to Citrix and VMware.
- Neverinstall eliminates the need for a delivery controller due to its browser-based access, resulting in cost savings.
### Operational Costs
- Windows OS/VDA Costs: Neverinstall saves approximately 85% compared to Citrix and VMware due to its non-necessity for the VDA license.
- IT Labor: Neverinstall reduces labor costs by up to 50% compared to Citrix and VMware highlighting less labor-intensive management.
- Energy Costs: Neverinstall reduces energy costs by up to 50% over three years.
### Cost Efficiency
- Over three years, Neverinstall results in total cost savings of 45.6% compared to Citrix ($550,938 for Neverinstall vs. $1,012,687 for Citrix) and 38.5% compared to VMware ($550,938 for Neverinstall vs. $896,099 for VMware).
Adopting [Neverinstall](https://neverinstall.com) for thin client devices offers significant cost savings in setup, operational, and maintenance expenses, making it the most economical choice over a three-year period.
This cost-effective solution does not compromise on performance to deliver these efficiency gains for your bottom line. The modernized architecture eliminates unnecessary components, improves latency, ensures stable connections even at very low internet speeds, andHere is the markdown version of the article:

1,886,502 | Pipe / Curry / HOF | PIPE A pipe function is used to compose multiple functions into a single function,... | 0 | 2024-06-13T04:57:59 | https://dev.to/__khojiakbar__/pipe-curry-hof-413j | pipe, curry, hof, javascript | #**PIPE**
> A pipe function is used to compose multiple functions into a single function, where the output of one function becomes the input of the next. It's a way to create a sequence of function calls.
```
let first = (i) => i + 10;
let second = (i) => i * 2;
let third = (i) => i + 2;
let res = third(second(first(2)))
console.log(res);
```
#**CURRY**
> Currying is a technique of transforming a function that takes multiple arguments into a sequence of functions, each taking a single argument. This can make functions more reusable and flexible.
```
function curry1(a) {
return(b) => {
return(c) => {
return(d) => {
return a+b+c+d
}
}
}
}
console.log(curry1(2)(10)(20)(30));
let curry2 = (a) => (b) => (c) => (d) => a+b+c+d
console.log(curry2(1)(2)(3)(4));
```
#**HOF**
> Higher-order functions are functions that take other functions as arguments or return functions as their result. They are a key feature of functional programming.
```
function app (func) {
return func
}
function childFunc() {
return ['one', 'two', 'three']
}
let res = app(childFunc())
console.log(res);
```
## **Differences**
**Pipe vs. Curry:**
**Pipe:** Composes multiple functions where the output of one function is passed as input to the next. It creates a function pipeline.
**Curry:** Transforms a function with multiple arguments into a sequence of functions each taking a single argument. It allows partial application of functions.
**Higher-Order Functions (HOFs):**
**HOFs:** Functions that either take other functions as arguments or return functions as their results. They are a broader concept that includes techniques like pipe and curry.
##**Summary**
**Pipe Function:** Used for function composition, creating a pipeline of functions.
**Curry Function: **Used for transforming a function to take arguments one at a time.
**Higher-Order Functions (HOFs):** Functions that operate on other functions, either by taking them as arguments or returning them.

1,885,611 | Understanding Tokens in Node.js and NestJS 🚀 | Hey there, fellow devs! 👋 Today, we're diving into the world of tokens in Node.js and NestJS. Tokens... | 27,583 | 2024-06-13T04:52:04 | https://dev.to/shahharsh/understanding-tokens-in-nodejs-and-nestjs-4a55 | backend, nestjs, node, jwt | Hey there, fellow devs! 👋 Today, we're diving into the world of tokens in Node.js and NestJS. Tokens are essential for securing our APIs and managing user sessions. Let's break down the most common types: **access tokens** and **refresh tokens**. Let's go! 🌟
## Access Tokens 🔑
Access tokens are like your VIP pass 🎟️ to the API. When you log in, the server gives you an access token, which you then use to access protected routes and resources.
### Key Points:
- **Short-lived**: Usually valid for a few minutes to an hour ⏳.
- **Stored in**: Browser storage (like localStorage) or HTTP-only cookies 🍪.
- **Usage**: Sent with each request (typically in the `Authorization` header as `Bearer <token>`).
### Example:
```javascript
// Example of using an access token in a request
fetch('https://api.example.com/protected', {
method: 'GET',
headers: {
'Authorization': 'Bearer your-access-token-here'
}
})
.then(response => response.json())
.then(data => console.log(data));
```
## Refresh Tokens 🔄
Refresh tokens are your backstage pass 🎫. They let you get a new access token without re-authenticating. When your access token expires, use the refresh token to get a new one.
### Key Points:
- **Long-lived**: Valid for days, weeks, or even months 📆.
- **Stored in**: HTTP-only cookies or secure storage on the server 🔒.
- **Usage**: Sent to a specific endpoint to obtain a new access token.
### Example:
```javascript
// Example of using a refresh token to get a new access token
fetch('https://api.example.com/refresh-token', {
method: 'POST',
credentials: 'include' // Ensure cookies are sent with the request
})
.then(response => response.json())
.then(data => {
const newAccessToken = data.accessToken;
// Use the new access token as needed
});
```
## JWT (JSON Web Tokens) 📜
Both access and refresh tokens are often implemented as JWTs. JWTs are compact, URL-safe tokens that contain a set of claims (user info, token validity, etc.) and are signed by the server.
### Structure of a JWT:
1. **Header**: Contains the type of token and the signing algorithm.
2. **Payload**: Contains the claims (e.g., user ID, expiration time).
3. **Signature**: Verifies the token’s authenticity.
### Example of a JWT:
```json
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
```
## Implementing Tokens in NestJS ⚙️
NestJS, with its robust module system, makes it straightforward to implement token-based authentication. Here’s a quick overview of how you might set it up:
### Step 1: Install Necessary Packages
```bash
npm install @nestjs/jwt @nestjs/passport passport passport-jwt
```
### Step 2: Configure JWT Module
```typescript
import { JwtModule } from '@nestjs/jwt';
@Module({
imports: [
JwtModule.register({
secret: 'yourSecretKey', // Change to a strong secret key
signOptions: { expiresIn: '1h' }, // Access token validity
}),
],
})
export class AuthModule {}
```
### Step 3: Create Auth Service
```typescript
import { Injectable } from '@nestjs/common';
import { JwtService } from '@nestjs/jwt';
@Injectable()
export class AuthService {
constructor(private readonly jwtService: JwtService) {}
async generateAccessToken(user: any) {
const payload = { username: user.username, sub: user.userId };
return this.jwtService.sign(payload);
}
async generateRefreshToken(user: any) {
const payload = { username: user.username, sub: user.userId };
return this.jwtService.sign(payload, { expiresIn: '7d' }); // Refresh token validity
}
}
```
### Step 4: Protect Routes with Guards
```typescript
import { Injectable, ExecutionContext } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';
@Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {
canActivate(context: ExecutionContext) {
// Add custom authentication logic here if needed
return super.canActivate(context);
}
}
// Apply the guard to your routes
@Controller('protected')
export class ProtectedController {
@UseGuards(JwtAuthGuard)
@Get()
getProtectedResource() {
return 'This is a protected resource!';
}
}
```
And there you have it! 🎉 You’re now ready to implement token-based authentication in your Node.js and NestJS applications. Whether you’re using access tokens for quick, ephemeral access or refresh tokens for long-term sessions, tokens keep your app secure and user-friendly.
Happy coding! 💻✨ | shahharsh |

1,883,777 | Implementing coroutines in Swift using Swift Concurrency | One of my favorite features of Lua is its first-class support for coroutines. Recently, I started... | 0 | 2024-06-13T04:00:00 | https://gist.github.com/MCJack123/f640242b729b487164fa9a6e297d365f | swift, coroutines | One of my favorite features of [Lua](https://www.lua.org) is its first-class support for coroutines. Recently, I started writing a new project using Swift, and I wanted to be able to use coroutines natively in my Swift code. In most Lua VMs, coroutines are a complex feature that require a lot of environmental support to be able to save and restore function calls. However, Swift includes the `async` and `await` keywords for pausing functions built into the language. Because of this, I decided to take a crack at using them to implement coroutines natively.
## What are coroutines?
A *coroutine* is an object that represents a function which can be paused and resumed. This function may pause (or *yield*) itself at any time, which will return execution to the code that last resumed the coroutine. The coroutine can then be resumed later, and the code will pick up right where it left off.
A coroutine also represents a call stack, or a thread of execution. The main function can call other functions that can yield, at which point the entire coroutine pauses without affecting any of the calling functions. For example, assume a coroutine was initialized with a function `foo`. If `foo` calls `bar`, and at some point `bar` yields, `foo`'s status will be completely unaffected, and in fact, `foo` will have no idea that `bar` even yielded.
In Lua's coroutines, yielding and resuming can also pass values between each coroutine. When yielding, a function can pass values back to its parent as return values from the corresponding resume call, and resuming can pass values to the corresponding yield call as well. This can be used to implement various design patterns, such as iterators, using a single function.
*An example of an iterator using coroutines.*
```lua
local function iterator(array)
-- Loop over the array normally.
for i = 1, #array do
-- Send the index and value back to the function.
coroutine.yield(i, array[i])
end
-- Send back nil to end the iteration.
return nil
end
local array = {"foo", "bar", "baz"}
-- Loop using a coroutine as an iterator function.
-- The function returned by `coroutine.wrap` is called with `array` for each iteration.
for index, value in coroutine.wrap(iterator), array do
print(index, value)
end
```
Coroutines can be used to implement a rudimentary form of cooperative multitasking. A set of tasks can each be placed in their own coroutines, and a master "coroutine manager" can resume each of those coroutines in order until they finish. When one coroutine yields, it lets another one continue its work. This can give the impression that the functions are running in parallel - they can update each other's states between yields, and may process information out-of-order from each other. Using this basic structure, more complex forms of multitasking can be implemented, like OS processes and threads.
*A diagram of how execution flows between two parallel coroutines.*
## Swift Concurrency
Swift Concurrency is a feature of the Swift language added in Swift 5.5. Its main feature is the `async` and `await` keywords, which allow functions to delegate long-running tasks to separate threads while the main code continues. This allows cooperative multitasking in a structured manner. These keywords may be familiar to JavaScript or Python developers, who have likely used this construct in those languages before.
Functions which are designated `async` may use the `await` keyword to call another `async` function with set arguments. This pauses execution of the current function, and allows other asynchronous tasks to complete. Once the `await`ed function returns, the original function is resumed with the return value (if used) sent back as the result of `await`.
To call an `async` function without waiting for a result, a `Task` object is used. The `Task` constructor takes a single `async` function, which may then call other `async` functions. A `Task` wraps around a call stack of `async` functions, representing a single thread of execution which can be paused and resumed. `Task`s are created in an execution pool, which schedules when each task will be run. Using `await` or calling `Task.yield()` will pause the current task and allows other `Task`s to resume.
*A model of how `async` functions can pause and resume in a single thread of execution.*
Some of these things may sound like parts of coroutines as discussed above. Both coroutines and `async` functions are able to be paused and resumed at certain points. Both coroutines and `await` can pass values to and from a subtask. Both coroutines and `Task`s represent a single thread of resumable execution.
However, there is one very important distinction between the two: coroutines have a parent-child relationship, where a coroutine resumes a child and yields to its parent; while `Task`s and their main `async` functions are run in a pool, and thus have no parents. To mitigate this, I decided to implement my own `Coroutine` class to hold the parent-child relationship.
## Initial implementation
To start, I created a `Coroutine` class with an initializer, a `resume` method, and a static `yield` function. The `resume` and `yield` methods take and return arrays of any value, which allows passing and returning multiple values. The initializer takes an `async` function for the body, which takes and returns `[Any]` arrays as well. To keep track of parent coroutines, I added a static `running` property, which holds the currently running coroutine.
```swift
public class Coroutine {
public static var running: Coroutine? = nil
public static func yield(with args: [Any]) async -> [Any] {}
public init(_ body: ([Any]) async -> [Any]) {}
public func resume(with args: [Any]) async -> [Any] {}
}
```
Each coroutine holds a single `Task` variable, which is what runs the functions and holds the call stack. To keep track of whether the coroutine is paused, running, normal (running but waiting on another coroutine), or dead, it also has a state property, which is an enum type.
```swift
public enum State {
case suspended
case running
case normal
case dead
}
public var state: State = .suspended
private var task: Task<Void, Never>! = nil // no return value, never throws
```
To implement the resuming and yielding functionality, I used the state variable to determine whether a task should continue. Resuming a coroutine involved setting the coroutine's status to running, and then waiting until it was no longer running. Likewise, yielding a coroutine would set the coroutine's status to suspended, and then waited until it was no longer suspended. This would ensure that only one coroutine was running at a time. An additional private member held the return values on each end.
```swift
private var results: [Any] = [Any]()
public func resume(with args: [Any] = [Any]()) async -> [Any] {
// Set the currently running coroutine, and make the previous coroutine have normal status.
let old = Coroutine.running
old?.state = .normal
Coroutine.running = self
// Set the coroutine to running, pass the return values, and wait for its task to yield.
results = args
state = .running
while state == .running {
await Task.yield()
}
// Reset the running coroutine to its previous value, and return with the yield's return values.
Coroutine.running = old
old?.state = .running
return results
}
public static func yield(with args: [Any] = [Any]()) async -> [Any] {
if let coro = Coroutine.running {
coro.results = args
coro.state = .suspended
while coro.state != .running {
await Task.yield()
}
return coro.results
}
}
```
The initializer function simply created a new `Task` using a small wrapper to handle the first resume and last return.
```swift
public init(_ body: ([Any]) async -> [Any]) {
task = Task {
// Wait for the task to be resumed for the first time.
while self.state != .running {
await Task.yield()
}
// Call the body function.
let res = await body(self.results)
// Set the coroutine as dead and set return values.
self.state = .dead
self.results = res
}
}
```
This approach worked, and my small test suite passed properly. However, astute readers will notice a huge hole in this approach. `Task.yield()` does not wait for anything - it simply lets other tasks step forward, and then resumes itself, which is why the `while` loop is required. This means that every coroutine is consuming 100% CPU until they get resumed, and because tasks can be delegated to multiple CPU cores, this can quickly overload the system.
Obviously, this isn't a suitable approach for a complete application. But luckily, there's a mechanism included in the concurrency features that helps fix this issue.
## Continuations
In JavaScript, many older asynchronous functions use a callback parameter to specify what code to run once the async task completes. The function itself would return immediately, but the callback function would be called (often with result parameters) after the asynchronous task was finished, which would continue the program's execution. But this often led to *callback hell*, a situation where a program gets extremely deeply nested because it used multiple asynchronous functions in series:
```js
fooAsyncCallback(a, b => {
barAsyncCallback(b, c => {
bazAsyncCallback(c, d => {
d.processCallback(res => {
console.log(res)
})
})
})
})
```
To fix this, JavaScript introduced the `Promise` type, which allowed async functions to be called in a serial manner using chains of `.then` calls:
```js
fooAsyncPromise(a)
.then(b => barAsyncPromise(b))
.then(c => bazAsyncPromise(c))
.then(d => d.processPromise())
.then(res => console.log(res))
```
Later on, `async`/`await` wrapped around this functionality by automatically breaking an `async` function into `Promise` callbacks during compilation, allowing true structured programming:
```js
let b = await fooAsyncPromise(a)
let c = await barAsyncPromise(b)
let d = await bazAsyncPromise(c)
let res = await d.processPromise()
console.log(res)
```
But this requires functions to implement a function that returns `Promise`s. If you're stuck with an old callback-based function, you normally have to break the chain and start a new one inside the callback. This is where the `Promise` constructor comes in. It takes another callback as an argument - but this callback is used to *call* the async function. The callback receives an argument called the *resolver*, which is used as the callback for the async function. This allows using callback-based functions with `Promise`s and `async`.
```js
let b = await fooAsyncPromise(a)
let c = await barAsyncPromise(b)
let d = await bazAsyncPromise(c)
let res = await new Promise(resolve => {
d.processCallback(resolve) // call the function using the resolver function
// calling resolve() will cause the await statement to continue
})
console.log(res)
```
Like JavaScript, Swift also has a procedure for using callback-style functions with `async`/`await`. A continuation represents the same thing as a JavaScript `Promise`, and works in a similar way.
To create a continuation, you use one of the `with*Continuation` global functions. There are four different functions, depending on whether you want a checked or unsafe continuation (more on that later), and a throwing or non-throwing callback function. These functions take a single block/closure, which takes a continuation object, which is then *resumed* inside the async function's callback.
Here's a translation of the above JavaScript code into Swift using closures:
```swift
let b = await fooAsync(a)
let c = await barAsync(b)
let d = await bazAsync(c)
let res = await withCheckedContinuation { continuation in
d.process { result in
continuation.resume(returning: result)
}
}
print(res)
```
One useful feature of the continuation functions is that **the currently running task gets paused until the continuation is resumed**. This is super handy when we're looking for a way to pause a task unconditionally. But a drawback of continuations is that they need to be resumed *exactly* once - the task can't just wait on the same continuation multiple times for multiple yields, and it also can't just leave the task hanging if the continuation's no longer needed, or the task will leak resources.
(This is where the checked/unsafe variants come into play - checked continuations have built-in checks to make sure they are resumed exactly once, while unsafe continuations don't. Checked continuations are usually used while debugging, and can be migrated to unsafe continuations to optimize for speed.)
Throwing continuations can also have errors passed as resume values using the `resume(throwing: Error)` method, which propagates the error back to the `with*ThrowingContinuation` function. The coroutine can use this to send errors back to the parent coroutine.
The coroutine will store a property that holds a continuation for later use. To pause a task, the coroutine will create a new continuation, and store it in the continuation property. After that, it'll resume the old continuation with the results to send. Finally, the `with*Continuation` function's block returns, which pauses the task, and waits for the continuation to be resumed.
## Putting it together
First, we'll update the `resume` function with continuations. We'll use `withCheckedThrowingContinuation` to create a checked, throwable continuation, which'll allow us to propagate errors back to the `resume` call.
```swift
public enum CoroutineError: Error {
case notSuspended
case noCoroutine
case cancel
}
private var continuation: CheckedContinuation<Void, Error>!
public func resume(with args: [Any] = [Any]()) async throws -> [Any] {
// Error if the coroutine isn't currently suspended.
if state != .suspended {
throw CoroutineError.notSuspended
}
// Set the currently running coroutine, and make the previous coroutine have normal status.
let old = Coroutine.running
old?.state = .normal
Coroutine.running = self
// NEW: Create a continuation, resume the coroutine, and wait for the coroutine to finish.
self.state = .running
let res = try await withCheckedThrowingContinuation {nextContinuation in
let c = continuation!
continuation = nextContinuation
c.resume(returning: args)
}
// Reset the running coroutine to its previous value, and return with the yield's return values.
Coroutine.running = old
old?.state = .running
return res
}
```
The `yield` function will work in a similar way. We'll take advantage of throwing errors later on.
```swift
public static func yield(with args: [Any] = [Any]()) async throws -> [Any] {
// Yielding does not work if there is no currently running coroutine.
if Coroutine.running == nil {
throw CoroutineError.noCoroutine
}
// Set the currently running coroutine as suspended.
let coro = Coroutine.running
coro!.state = .suspended
// Create a new continuation, and wait for its response.
return try await withCheckedThrowingContinuation {continuation in
let c = coro!.continuation!
coro!.continuation = continuation
c.resume(returning: args)
}
}
```
The initializer function will also be modified to use a continuation, instead of busy waiting for the first resume. But we need to wait a little bit for the task to store the coroutine - otherwise, the `resume` method could be called before the continuation is set.
```swift
public init(for body: @escaping ([Any]) async throws -> [Any]) async {
// Create the task.
task = Task {
// Create the continuation for the first resume.
let args = try await withCheckedThrowingContinuation {continuation in
self.continuation = continuation
}
do {
// Call the body function.
let res = try await body(args)
// Set the coroutine as dead, and send the result back as the final yield.
self.state = .dead
self.continuation.resume(returning: res)
} catch {
// Catch any thrown errors, and throw them back to the parent resume.
self.state = .dead
self.continuation.resume(throwing: error)
}
}
// Wait for the continuation to be created in the other task.
while continuation == nil {
await Task.yield()
}
}
```
This code will work fine for running coroutines normally. However, if a coroutine is deleted before its body returns or errors, the task will be left hanging because the continuation was never resumed. This will also print a warning message to the console, since we're using checked continuations.
To resolve this, we'll add a deinitializer to resume the continuation. We'll resume it with an error to make the function exit as quickly as possible. This means that body functions will need to make sure to propagate the `.cancel` error up to the main function, which is a bit annoying, but I haven't figured out to get around this yet.
```swift
deinit {
if _state == .suspended {
continuation.resume(throwing: CoroutineError.cancel)
}
}
```
Finally, we need to tweak the initializer and `yield` to use a weak reference to the coroutine, as these will make the task enter a retain cycle until the task completes.
```swift
public init(for body: @escaping ([Any]) async throws -> [Any]) async {
// Create the task.
// NEW: Use a weak self to avoid retaining the coroutine inside itself.
task = Task { [weak self] in
// Create the continuation for the first resume.
let args = try await withCheckedThrowingContinuation {continuation in
self!.continuation = continuation
}
do {
// Call the body function.
let res = try await body(args)
// Set the coroutine as dead, and send the result back as the final yield.
self?.state = .dead
self?.continuation.resume(returning: res)
} catch {
// Catch any thrown errors, and throw them back to the parent resume.
self?.state = .dead
self?.continuation.resume(throwing: error)
}
}
// Wait for the continuation to be created in the other task.
while continuation == nil {
await Task.yield()
}
}
public static func yield(with args: [Any] = [Any]()) async throws -> [Any] {
// Yielding does not work if there is no currently running coroutine.
if Coroutine.running == nil {
throw CoroutineError.noCoroutine
}
// Set the currently running coroutine as suspended.
// NEW: Use an unowned reference to avoid retaining the coroutine after yielding.
unowned let coro = Coroutine.running
coro!.state = .suspended
// Create a new continuation, and wait for its response.
return try await withCheckedThrowingContinuation {continuation in
let c = coro!.continuation!
coro!.continuation = continuation
c.resume(returning: args)
}
}
```
## Wrapping up
Coroutines are a useful primitive for various tasks both synchronous and asynchronous. Using Swift's comprehensive concurrency model, we can implement a coroutine object in less than 100 lines of code. This approach can also be used in other languages that have similar constructs, including JavaScript.
The complete library source is listed [in this Gist](https://gist.github.com/MCJack123/f640242b729b487164fa9a6e297d365f). This version includes a couple of additions, like the ability to call the coroutine directly to resume it. It's donated to the public domain, so feel free to use it in any project, but I'd appreciate a link back to this article as a reference. | jackmacwindows |

1,886,497 | The Future of Web Development: Exploring WebAssembly (Wasm) | Hey everyone! 👋 Today, I want to dive into something that's truly revolutionizing the web... | 0 | 2024-06-13T04:43:06 | https://dev.to/a_a_b6c834ea264e0ac7ef46c/the-future-of-web-development-exploring-webassembly-wasm-5b5k | webdev | Hey everyone! 👋
Today, I want to dive into something that's truly revolutionizing the web development landscape: **WebAssembly (Wasm)**. If you haven't heard about it yet, buckle up because this is one cutting-edge technology that's set to change how we build web applications.
**What is WebAssembly?**
WebAssembly (Wasm) is a binary instruction format designed as a portable target for the compilation of high-level languages like C, C++, and Rust. It enables developers to run code written in these languages at near-native speed on web browsers. The best part? It's designed to be a complement to JavaScript, not a replacement.
**Why is WebAssembly a Game-Changer?**
1. **Performance**: One of the biggest advantages of WebAssembly is its performance. Unlike JavaScript, which is interpreted, WebAssembly code is compiled into a binary format that can be executed directly by the browser's JavaScript engine. This means WebAssembly can run at near-native speed, making it ideal for performance-critical applications like games, video editing, and scientific simulations.
2. **Portability**: WebAssembly is designed to be portable across different platforms. This means you can compile your code once and run it anywhere, from desktops to mobile devices to servers.

**
1. **Gaming**
The gaming industry is one of the biggest beneficiaries of WebAssembly. Games require high performance and WebAssembly can deliver that in the browser. For example, popular game engines like Unity and Unreal Engine are leveraging WebAssembly to bring high-quality games to the web.
2. **Video and Image Editing**
WebAssembly allows for powerful video and image editing tools to run directly in the browser. This is particularly useful for applications that require intensive processing, such as Adobe Photoshop, which is now available as a web app using WebAssembly.
3. **Scientific Simulations**
WebAssembly enables complex scientific simulations to run in the browser with high performance. This opens up new possibilities for scientific research and education, making powerful tools more accessible.
4. **Cryptography**
WebAssembly is also being used in the field of cryptography. Libraries like WebAssembly-crypto provide high-performance cryptographic functions that can be run securely in the browser.
**Getting Started with WebAssembly
**
If you're excited about the potential of WebAssembly and want to get started, here's a simple example using AssemblyScript, a TypeScript-like language that compiles to WebAssembly.
1. **Install AssemblyScript**:
```bash
npm install -g assemblyscript
```
2. **Create a simple AssemblyScript file** (`hello.ts`):
```typescript
export function add(a: i32, b: i32): i32 {
return a + b;
}
```
3. **Compile to WebAssembly**:
```bash
asc hello.ts -b hello.wasm -O3
```
4. **Load WebAssembly in JavaScript**:
```html
<!DOCTYPE html>
<html>
<body>
<script>
fetch('hello.wasm')
.then(response => response.arrayBuffer())
.then(bytes => WebAssembly.instantiate(bytes))
.then(results => {
const add = results.instance.exports.add;
console.log(add(2, 3)); // Outputs: 5
});
</script>
</body>
</html>
```
**Conclusion**
WebAssembly is truly a groundbreaking technology that extends the capabilities of web development far beyond what was previously possible with JavaScript alone. Its performance, portability, and security make it a powerful tool for building the next generation of web applications.

1,886,494 | Infra as GitHub Actions - AWS Serverless Function for nodejs | In the last post we talked about the need to simplify infra while also moving it back to the... | 0 | 2024-06-13T04:27:34 | https://mymakerspace.substack.com/p/infra-as-github-actions-aws-serverless | javascript, aws, githubactions, terraform |
In the last [post](https://dev.to/aws-builders/provisioning-aws-solutions-in-minutes-with-infra-as-github-actions-c25) we talked about the need to simplify infra while also moving it back to the application repo
As I started to work on the next infra as GitHub actions, which was a secured website with `authentication@edge`. It became clear that AWS lambda was a fundamental building block in the journey
Introducing [actions-aws-function-node](https://github.com/alonch/actions-aws-function-node) 🎉
Now with very few dependencies, you can provision your node backend in literally a minute 🏎️
## Getting started
Let's start with familiar code
```javascript
// src/index.js
exports.handler = async (event, context) => {
return {
"statusCode": 200,
"headers": {
"Content-Type": "*/*"
},
"body": "hello world"
}
}
```
Add the workflow
```
# .github/workflows/on-push-main.yml
name: demo
on:
push:
branches:
- main
jobs:
deploy:
environment:
name: main
url: ${{ steps.backend.outputs.url }}
permissions:
id-token: write
runs-on: ubuntu-latest
steps:
- name: Check out repo
uses: actions/checkout@v4
- uses: aws-actions/configure-aws-credentials@v4
with:
aws-region: us-east-1
role-to-assume: ${{ secrets.ROLE_ARN }}
role-session-name: ${{ github.actor }}
- uses: alonch/actions-aws-backend-setup@main
with:
instance: sample
- uses: alonch/actions-aws-function-node@main
with:
name: actions-aws-function-node-sample
entrypoint-file: index.js
entrypoint-function: handler
artifacts: src
allow-public-access: true
```
Add the secret `ROLE_ARN` with access to AWS and that's it, after pushing to main you have a GitHub deployment with you backend running 🎉
You can clone this [sample](https://github.com/alonch/actions-aws-function-node-sample) from Github too
Of course, there are a lot more options
## Permissions
You can allow access to services by just adding the resource name and the access, either read or write
For example:
```
- uses: alonch/actions-aws-function-node@main
with:
name: actions-aws-function-node-demo
entrypoint-file: index.js
entrypoint-function: handler
artifacts: src
allow-public-access: true
permissions: |
s3: read
dynamodb: write
```
This configuration will attach AmazonS3ReadOnly and AmazonDynamoDBFullAccess managed policies to the function's role
## Environment Variables
Similar to permissions, you can attach function variables as follow:
```
- uses: alonch/actions-aws-function-node@main
with:
name: actions-aws-function-node-demo
entrypoint-file: index.js
entrypoint-function: handler
artifacts: src
allow-public-access: true
env: |
DD_ENV: production
DD_SERVICE: demo
DD_VERSION: ${{ github.sha }}
```
The rest of the options are standard attributes like memory, timeout or selecting ARM architecture
The best part is that it takes a minute to provision it and even less time to destroy 👏
I’m excited about the future developments and improvements that can be made to this workflow. If you have any feedback, questions, or suggestions, feel free to leave a comment below or reach out directly. Let’s continue this journey of simplifying infrastructure together!
Thank you for reading, and happy coding! | alonch |

### 1. Define SEO Fields in Sitecore
First, ensure your Sitecore templates include fields for SEO metadata:
- Title
- Meta Description
- Meta Keywords
You can add these fields to your base template or specific templates.
### 2. Create a GraphQL Query to Fetch SEO Metadata
Define a GraphQL query to fetch the SEO metadata for the current page.
```graphql
// seoQuery.graphql
query GetSEOMetadata($path: String!) {
item(path: $path) {
fields {
title {
value
}
metaDescription {
value
}
metaKeywords {
value
}
}
}
}
```
### 3. Create a Custom SEO Component in Next.js
Create a custom SEO component that uses the GraphQL query to fetch the SEO metadata and sets the appropriate meta tags.
```typescript
// components/SEO.js
import React from 'react';
import Head from 'next/head';
import { useQuery, gql } from '@apollo/client';
const SEO_QUERY = gql`
query GetSEOMetadata($path: String!) {
item(path: $path) {
fields {
title {
value
}
metaDescription {
value
}
metaKeywords {
value
}
}
}
}
`;
const SEO = ({ pagePath }) => {
const { data, loading, error } = useQuery(SEO_QUERY, { variables: { path: pagePath } });
if (loading) return null;
if (error) return <p>Error: {error.message}</p>;
const { title, metaDescription, metaKeywords } = data.item.fields;
return (
<Head>
<title>{title.value}</title>
<meta name="description" content={metaDescription.value} />
<meta name="keywords" content={metaKeywords.value} />
<link rel="canonical" href={`https://www.yoursite.com/${pagePath}`} />
</Head>
);
};
export default SEO;
```
### 4. Integrate the SEO Component into Your Pages
Use the custom SEO component in your Next.js pages to dynamically set the SEO metadata.
```typescript
// pages/[...path].js
import { useRouter } from 'next/router';
import { initializeApollo } from '../lib/apolloClient';
import SEO from '../components/SEO';
import { SEO_QUERY } from '../queries/seoQuery';
const Page = ({ initialApolloState, pagePath }) => {
const router = useRouter();
if (router.isFallback) {
return <div>Loading...</div>;
}
return (
<>
<SEO pagePath={pagePath} />
{/* Page content */}
</>
);
};
export async function getStaticPaths() {
// Fetch paths for static generation
return {
paths: [],
fallback: true,
};
}
export async function getStaticProps(context) {
const pagePath = context.params.path.join('/');
const client = initializeApollo();
await client.query({
query: SEO_QUERY,
variables: { path: pagePath },
});
return {
props: {
initialApolloState: client.cache.extract(),
pagePath,
},
revalidate: 10, // Revalidate every 10 seconds
};
}
export default Page;
```
### 5. Ensure Proper Handling of Dynamic Routing
Ensure your dynamic routing in Next.js is correctly set up to handle various paths and fetch the appropriate SEO data.
```typescript
// next.config.js
module.exports = {
async rewrites() {
return [
{
source: '/:path*',
destination: '/:path*',
},
];
},
};
```
## Conclusion
Combining best practices with a custom SEO implementation in Sitecore XM Cloud and Next.js ensures that your content is optimized for search engines and performs well in search rankings. By leveraging Sitecore’s robust content management capabilities and Next.js’s performance features, you can create a highly optimized site that is both user-friendly and search-engine-friendly.

1,886,174 | How I created a web server for my portfolio | Hi 👋 My name is Eric, and I am a full-stack software engineer at ALX. I have extensive... | 0 | 2024-06-13T04:11:28 | https://dev.to/vulcanric/how-i-created-a-web-server-for-my-portfolio-3j7e | ### Hi :wave:
My name is Eric, and I am a full-stack software engineer at ALX. I have extensive experience in DevOps, Front-end development, and Socket/Network programming while specializing in Back-end development.
My favorite programming language is C ✨ (I really enjoy coding in C). Perhaps it's because C was the first language I learned as a programmer, though I also code in other languages like Python and JavaScript.
### The main thing
At ALX, where I study, we reached a point where we needed to create impressive projects to enhance our resumes as aspiring software developers.
The main challenge was deciding on a project idea; otherwise, I would have to work on the default project (a 2D Maze game built in C).
After days of contemplation, I decided to build an HTTP web server in C, leveraging its power and efficiency. Recognizing that this would be a challenging project, requiring extensive technical expertise and a logical workflow, I embraced the challenge. I thrive on tackling projects that push my boundaries.
Here are the workings of my web server:
With the goal of building a minimalist web server that I could enhance with additional features over time, I began with the basics. I created a TCP socket, bound it to my server's address, and set it to listen for incoming connections on a specific port. Initially, I used a buffer filled with static HTML content to respond to any requests from web clients (whether from a browser or curl), regardless of the request specifics. This approach allowed me to test the server's functionality.
Here was the first time my web server worked:
Seeing this, I was filled with excitement and proceeded to implement a configuration settings feature. This allowed me to configure which port the server listens on, what folder it serves web content from, and more. The challenge was creating a format for the configuration file. To keep it simple, easy to understand, and straightforward to write, I developed a very simple format similar to that of nginx.
```bash
server <SERVER_NAME>:
listen <PORT>
root <ROOT_FOLDER>
index index.html
location / :
check <URI> FOUND?200:404
```
During this project, I encountered a challenging bug: an invalid pointer! While developing the configuration engine—a tool that parses and processes the configuration file—I kept seeing a `free(): invalid pointer` error. I searched my code thoroughly to ensure all allocated memory was properly freed, but couldn't identify the issue.
After an hour of frustration, I decided to use `printf()` with the address-of-format specifier for debugging. By placing `printf("Address of buff: %p\n", &MALLOCD_BUFF)` at various points, I tracked the addresses of buffers at different stages. This helped me discover that the buffer's address in memory was slightly higher when freed than when declared. The issue arose because, within the configuration processor, the pointer was incremented by one to skip initial tab characters in each line of the file.
Here's a diagram to better illustrate the problem:
```bash
# This is the configuration file
# The escape sequence <\t> signifies a tab
server example.com:
<\t>listen 80
<\t>root /var/www/html
<\t>index index.html index.eric.html
<\t><\t>location / :
<\t><\t><\t>check $uri $uri/ FOUND?200:404
```
```C
/* Inside the configuration file processor */
char *line = NULL;
size_t linesize = 0;
getline(&line, &linesize, config_file); /* address of the first char pointed to by @line is #7ADF5431 */
/* Skip as many tabs found beginning the line */
while (*line == '\t')
line++; /* This statement moves the address #7ADF5431 to + 1 (next char) */
free(line); /* When freeing the line buffer, the wrong address is being freed */
/* It's freeing address #7ADF5431 + 1 + ... instead of address #7ADF5431 */
```
To solve this problem, I used a variable to count the number of addresses in memory moved forward by the statement `line++`. and decrements them as required before freeing them, and that was it! I no longer get the error `Invalid pointer`.
```C
/* Inside the configuration file processor */
char *line = NULL;
size_t linesize = 0;
int memcount = 0; /* Memory address counter */
while (getline(&line, &linesize, config_file) != -1) /* Read each line in the file */
{
/* Cuts off all the starting tab characters */
while (*line == '\t')
{
line++; /* Move to the next character in memory */
memcount++; /* Count the number of characters moved to */
}
/* Skip commented lines */
if (*line == '#')
{
while (memcount > 0)
{
line--; /* Go back to the first address allocated in memory */
memcount--;
}
free(line); /* Now free the right address */
continue; /* Go to the next line in file. There is nothing to do here */
}
/* Process line */
...
/* Free line */
while (memcount > 0)
{
line--; /* Go back to the first address allocated in memory */
memcount--;
}
free(line); /* Now free the right address */
}
```
Now, I faced the trickiest part of the project—the workflow!
If you’re a socket programmer or a Linux enthusiast, you know that multi-tasking is crucial for web servers and any socket-related software/hardware. Through my research, I learned about [race conditions](https://www.javatpoint.com/race-condition-in-operating-system), where multiple processes compete for a resource in a multiprocessing/multithreaded environment. One process might alter a resource, affecting the outcome for others.
To ensure a functional server, high levels of isolation and independence are essential. How did I achieve this? I avoided having any single function do too much, as overburdened functions become dependent on many things, causing conflicts between processes calling them. Instead, I created numerous functions and handlers, each responsible for a specific task. This approach maximized independence and ensured the overall functionality of the server.
With these strategies and more, I successfully built a fully functional web server in C.

1,886,445 | Comparing Sitecore XP (.NET) and Sitecore XM Cloud (TypeScript): Solr vs. GraphQL for Queries | In the realm of Sitecore development, the shift from Sitecore XP (.NET) to Sitecore XM Cloud... | 0 | 2024-06-13T03:59:36 | https://dev.to/sebasab/comparing-sitecore-xp-net-and-sitecore-xm-cloud-typescript-solr-vs-graphql-for-queries-54n3 | sitecore, headless, solr, graphql | In the realm of Sitecore development, the shift from Sitecore XP (.NET) to Sitecore XM Cloud (TypeScript) marks a significant evolution. One of the most notable changes lies in the query mechanisms used to retrieve and manage data. While Sitecore XP relies on Solr, a powerful search platform, Sitecore XM Cloud leverages GraphQL, a modern query language for APIs. This blog will explore the differences between these two approaches, highlighting their respective benefits and drawbacks.
## Sitecore XP (.NET) Overview
Sitecore XP is a comprehensive digital experience platform that uses .NET as its foundation. It provides robust content management capabilities and is known for its flexibility and extensibility. A key component of Sitecore XP is Solr, an open-source search platform used for indexing and searching content.
## Sitecore XM Cloud (TypeScript) Overview
Sitecore XM Cloud represents the next generation of Sitecore, built on a headless architecture and utilizing TypeScript for development. This cloud-based platform emphasizes scalability and ease of integration with modern front-end frameworks. GraphQL plays a pivotal role in Sitecore XM Cloud, offering a powerful and flexible way to query content.
## Solr in Sitecore XP
Integration with Sitecore XP: Solr is tightly integrated with Sitecore XP, acting as the backbone for content search and indexing. Developers interact with Solr through Sitecore's Content Search API.
Querying with Solr: Here's an example of a complex Solr query in Sitecore XP, including filters for template, publish date, and path, as well as faceting by author and category:
### Step 1: Define the Model
First, define a model to map the search results. This model will represent the data structure returned from Solr.
```c#
public class ArticleSearchResultItem : SearchResultItem
{
[IndexField("title")]
public string Title { get; set; }
[IndexField("publishDate")]
public DateTime PublishDate { get; set; }
[IndexField("author")]
public string Author { get; set; }
[IndexField("category")]
public string Category { get; set; }
}
```
### Step 2: Create the Controller
Next, create a controller to handle the search logic.
```c#
using System;
using System.Linq;
using System.Web.Mvc;
using Sitecore.ContentSearch;
using Sitecore.ContentSearch.Linq.Utilities;
using Sitecore.Mvc.Controllers;
public class SearchController : SitecoreController
{
public ActionResult Articles()
{
using (var context = ContentSearchManager.GetIndex("sitecore_web_index").CreateSearchContext())
{
var query = context.GetQueryable<ArticleSearchResultItem>()
.Where(item => item.TemplateId == TemplateIDs.Article)
.Where(item => item.PublishDate >= DateTime.Now.AddMonths(-6))
.Where(item => item.Paths.Contains(new ID("{110D559C-39F8-42D9-8F0A-82B7A6FFFE20}"))) // Filtering by a specific path
.FacetOn(item => item.Author)
.FacetOn(item => item.Category);
var results = query.GetResults();
var model = new ArticleSearchViewModel
{
Articles = results.Hits.Select(hit => hit.Document).ToList(),
AuthorFacets = results.Facets.Categories["author"].Values,
CategoryFacets = results.Facets.Categories["category"].Values
};
return View(model);
}
}
}
```
### Step 3: Create the ViewModel
Create a ViewModel to pass data to the view.
```c#
using System.Collections.Generic;
using Sitecore.ContentSearch.Linq;
public class ArticleSearchViewModel
{
public List<ArticleSearchResultItem> Articles { get; set; }
public List<FacetValue> AuthorFacets { get; set; }
public List<FacetValue> CategoryFacets { get; set; }
}
```
### Step 4: Create the View
Finally, create the view to display the search results.
```c#
@model YourNamespace.ArticleSearchViewModel
<h2>Search Results</h2>
@foreach (var article in Model.Articles)
{
<div>
<h3>@article.Title</h3>
<p>@article.PublishDate.ToString("yyyy-MM-dd")</p>
<p>@article.Author</p>
<p>@article.Category</p>
</div>
}
<h3>Author Facets</h3>
@foreach (var facet in Model.AuthorFacets)
{
<div>
<p>@facet.Name (@facet.AggregateCount)</p>
</div>
}
<h3>Category Facets</h3>
@foreach (var facet in Model.CategoryFacets)
{
<div>
<p>@facet.Name (@facet.AggregateCount)</p>
</div>
}
```
## GraphQL in Sitecore XM Cloud
Integration with Sitecore XM Cloud: GraphQL is integrated directly into Sitecore XM Cloud, providing a unified query interface for developers. The use of GraphQL aligns well with modern JavaScript and TypeScript front-end frameworks.
Querying with GraphQL: Here's an example of a complex GraphQL query in Sitecore XM Cloud, including filters for template, publish date, and path, along with nested queries and fields for author and category:
### Step 1: Define the Model
Define a TypeScript interface for the data returned from the GraphQL query.
```typescript
export interface Article {
id: string;
name: string;
fields: {
title: {
value: string;
};
publishDate: {
value: string;
};
author: {
value: string;
};
category: {
value: string;
};
};
}
export interface ArticlesQueryResult {
item: {
id: string;
name: string;
children: {
results: Article[];
};
};
}
```
### Step 2: Create the GraphQL Query
Create the GraphQL query as a constant.
```typescript
import gql from 'graphql-tag';
export const ARTICLES_QUERY = gql`
{
item(path: "/sitecore/content/Home") {
id
name
children(filter: { field: "template", value: "Article", operator: EQ }) {
results(filter: { field: "publishDate", operator: GTE, value: "2023-01-01" }) {
id
name
fields {
title {
value
}
publishDate {
value
}
author {
value
}
category {
value
}
}
}
}
}
}
`;
```
### Step 3: Create the Component
Create a React component to execute the GraphQL query and render the results using Apollo Client.
```typescript
import React from 'react';
import { useQuery } from '@apollo/client';
import { ARTICLES_QUERY, ArticlesQueryResult } from './queries';
import { Article } from './models';
const Articles: React.FC = () => {
const { loading, error, data } = useQuery<ArticlesQueryResult>(ARTICLES_QUERY);
if (loading) return <p>Loading...</p>;
if (error) return <p>Error: {error.message}</p>;
const articles = data?.item.children.results || [];
return (
<div>
<h2>Search Results</h2>
{articles.map((article: Article) => (
<div key={article.id}>
<h3>{article.fields.title.value}</h3>
<p>{new Date(article.fields.publishDate.value).toLocaleDateString()}</p>
<p>{article.fields.author.value}</p>
<p>{article.fields.category.value}</p>
</div>
))}
</div>
);
};
export default Articles;
```
### Step 4: Integrate with the Application
Integrate the Articles component into your Next.js application, typically in a page or another component.
```typescript
import React from 'react';
import Articles from '../components/Articles';
const ArticlesPage: React.FC = () => {
return (
<div>
<h1>Articles</h1>
<Articles />
</div>
);
};
export default ArticlesPage;
```
## Comparison of Solr and GraphQL
**Performance Considerations**: Solr is optimized for complex search queries and large datasets, making it ideal for scenarios with heavy search requirements. GraphQL, on the other hand, excels in efficiency by allowing clients to request only the data they need, reducing over-fetching and under-fetching issues.
**Flexibility and Ease of Use**: GraphQL provides greater flexibility in querying, allowing developers to shape the response to fit their needs precisely. Solr's query syntax can be more rigid and complex, particularly for those unfamiliar with search engines.
**Developer Experience**: GraphQL aligns well with modern development practices and integrates seamlessly with JavaScript/TypeScript frameworks. Solr, while powerful, may present a steeper learning curve and require more specialized knowledge.
**Scalability and Maintenance**: Both Solr and GraphQL are scalable, but they cater to different needs. Solr is well-suited for heavy search operations, whereas GraphQL offers simplicity and efficiency for general content querying and management.
## Conclusion
Both Solr and GraphQL bring unique strengths to the table in the context of Sitecore development. Solr's robust search capabilities make it a strong choice for content-heavy applications in Sitecore XP. In contrast, GraphQL's flexibility and modern approach to data querying align perfectly with the headless architecture of Sitecore XM Cloud. Ultimately, the choice between Solr and GraphQL will depend on the specific needs and goals of your project.
