Both are stellar... | 0 | 2024-06-25T12:08:58 | https://dev.to/aaikansh_22/a-feature-rich-and-cheaper-developer-tool-than-retool-c46 | development, developers, lowcode, softwaredevelopment | In the world of low-code platforms, you’ve probably heard of Retool and DronaHQ. Both are stellar tools for building internal applications. But after using both for some time now, I’ve come to appreciate what DronaHQ brings to the table. I am **pleased with the UI building capabilities, visual workflow builder, and engineering support** they provide.
So, let’s talk about why you might want to jump ship from Retool and give [DronaHQ](https://www.dronahq.com/) a spin.
## **1. User-Friendly Interface That Doesn’t Sacrifice Power**
**Multi-Screen/Page Apps:** One of the standout features of DronaHQ is its support for multi-screen and multi-page applications. This means you can create complex, multi-functional apps all within a single project. Even better, the same app can be seamlessly deployed on mobile devices without the need for separate builds. Retool doesn’t quite match this level of flexibility out of the box.
**Custom UI Components:** DronaHQ offers a control designer where you can build custom UI components with any styling you want. This is a game-changer for teams that need highly specific interfaces and aren’t satisfied with the standard component library. With this level of customization, your apps can look exactly how you envision them.
**Enhanced Charting Options:** If you’re a data junkie, you’ll love DronaHQ’s charting facilities. It supports advanced charting options like **Plotly charts**, which provide richer, more interactive visualizations compared to standard options. Whether you’re tracking sales data or visualizing complex datasets, DronaHQ has you covered.
## **2. Killer Pre-Built Connectors and Integrations**
Integrations are the lifeblood of internal tools. Retool has a solid lineup, but **DronaHQ’s pre-built connectors and integration options are next level**. Whether you’re pulling data from Salesforce, writing to a MySQL database, or interacting with custom APIs, DronaHQ makes it straightforward.
Need to sync customer data from HubSpot into your app? DronaHQ’s pre-built HubSpot connector gets you there with minimal setup. No need to build from scratch, just plug and play.
## **3. Simplified Workflow Creation with Visual Builder**
Imagine setting up an approval process for expense reports. In Retool, you’d manually define each action and transition, which can get confusing fast. With DronaHQ, you simply click on the elements to create a clear, **visual representation of your workflow**. This not only simplifies the building process but also makes it easier for team members to understand and follow the logic.
## **4. Support That Doesn’t Ghost You**
Retool tends to focus primarily on enterprise deals exceeding $100k per customer, which often means small and medium-sized enterprises (SMEs) don’t get the attention they deserve. New and existing customers might find themselves waiting for help when they need it most.
In contrast, DronaHQ offers smooth and reliable support. During a critical product launch, you encounter a last-minute issue with your app. With **DronaHQ’s 24/7 support**, you can get immediate help, ensuring your launch goes off without a hitch.
## **5. Cost-Effective without Compromising Features**
Let’s talk money. Retool can get pricey, especially as your team scales. DronaHQ offers competitive pricing, making it an attractive option for startups, growing companies, and even enterprises that need to keep an eye on the budget without compromising on features.
As your team grows and your application needs to expand, DronaHQ’s pricing remains manageable in fact, **DronaHQ offers up to a 50% discount if you [migrate your apps from Retool](https://www.dronahq.com/retool-app-migration/) to DronaHQ**. Plus, their feature-rich free tier is nothing to scoff at — it’s perfect for getting started. By this, I meant **DronaHQ offers a [free one-month trial](https://www.dronahq.com/signup/) of its business plan** where you will get to see some premium features like branding, custom domain, custom SSO, and more.
## **How Easy Is It to Switch from Retool to DronaHQ Now?**
Let’s get real for a moment. Transitioning from one platform to another isn’t always smooth sailing, but DronaHQ makes the process as painless as possible.
With comprehensive documentation, responsive support, and a vibrant community, you’ll find the help you need when you need it. | aaikansh_22 |

I use Highlight.js on my personal website and wanted this feature to be able to quickly copy things I re-use so I looked at their [Plugin API](https://highlightjs.readthedocs.io/en/latest/plugin-api.html) and was pleasantly surprised at how easy it was to extend.
The snippet below is all you need to add a copy button to your code blocks highlighted with Highlight.js. 😄
```ts
hljs.addPlugin({
"after:highlightElement": ({ el, text }) => {
/**
* el is the <code> element that was highlighted
* el.parentElement is the <pre> element
*/
const wrapper = el.parentElement;
if (wrapper == null) {
return;
}
/**
* Make the parent relative so we can absolutely
* position the copy button
*/
wrapper.classList.add("relative");
const copyButton = document.createElement("button");
copyButton.classList.add(
"absolute",
"top-2",
"right-2",
"p-2",
"text-gray-500",
"hover:text-gray-700",
);
// Lucide copy icon
copyButton.innerHTML = `<svg class="h-4 w-4" xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-copy"><rect width="14" height="14" x="8" y="8" rx="2" ry="2"/><path d="M4 16c-1.1 0-2-.9-2-2V4c0-1.1.9-2 2-2h10c1.1 0 2 .9 2 2"/></svg>`;
copyButton.onclick = () => {
navigator.clipboard.writeText(text);
// Notify user that the content has been copied
toast.success("Copied to clipboard", {
description: "The code block content has been copied to the clipboard.",
});
};
// Append the copy button to the wrapper
wrapper.appendChild(copyButton);
},
});

It allows you to define methods on the child component that can be called from the parent component.
<u>forwardRef: </u>This is a React higher-order component that allows a parent component to directly interact with a child component's ref. It forwards the ref through the component to one of its child DOM nodes.
<h3>State Management:</h3>useState hook is used to create a state variable toggle with an initial value of false.
setToggle is the function to update the toggle state.
<h3>Forwarding the Ref:</h3>The Button component is wrapped with forwardRef to forward the ref to its internal DOM or methods.
<h3>Using useImperativeHandle:</h3>Inside useImperativeHandle, we define an object with the method alterToggle.
alterToggle method toggles the value of toggle state.
This method will be exposed to the parent component through the ref.
<h3>Rendering:</h3>The component renders a button with the text "Button From Child".
If toggle is true, it also renders a <span> with the text "Toggle".
<h3>Creating a Ref:</h3>useRef hook is used to create a ref called buttonRef. This ref will be used to access the alterToggle method defined in the Button component.
<h3>Parent Button:</h3>A button is rendered with the text "Button From Parent".When this button is clicked, it calls buttonRef.current.alterToggle(). This triggers the alterToggle method in the Button component, toggling the toggle state.
<h3>Child Button:</h3>The Button component is rendered with ref={buttonRef}, which forwards the buttonRef to the Button component, making the alterToggle method accessible to the parent.
## Summary
<u>forwardRef:</u> Allows the parent to pass a ref to the child component.
<u>useImperativeHandle:</u> Exposes custom methods (alterToggle in this case) from the child component to the parent component through the ref.
This pattern is useful when you need to control a child component imperatively, especially when dealing with complex or non-trivial UI interactions that are difficult to achieve through props alone.

In this article, we will dive deeper into the topic of DI in Elixir, focusing on the Rewire library for Elixir projects.
We will cover Rewire's core concepts, how to get started with it, and practical examples. We will also see how to use Rewire alongside Mox.
Let's get started!
## Introduction to Rewire
One of the challenges we faced in our previous article was the lack of a structured way to define and inject dependencies into our modules. We had to manually define our mocks for testing.
This is where Rewire and Mox come into play:
- **Rewire** provides a more structured and flexible way to implement DI in Elixir projects.
- **Mox** is a library that allows us to define mocks for our tests.
Combining these two tools can significantly improve the testability and modularity of our Elixir applications.
Let's get started by setting up a sample project that leverages both libraries.
## Why Use Rewire and Mox for Elixir?
To recap part one of the series, we discussed the benefits of DI for testability and modularity. We saw how we can use pass-in dependencies via function parameters:
- We have the `EmailScanner` module that relies on a `SpamFilterService` to check if an email is spam or not:
```elixir
defmodule EmailScanner do
def scan_email(spam_filter_service, email) do
spam_filter_service.check_spam(email)
end
end
```
- We have the `SpamFilterService` module that implements the spam checking logic:
```elixir
defmodule SpamFilterService do
def check_spam(email_content) do
String.contains?(email_content, "spam")
end
end
```
- We also have a `MockSpamFilterService` module that implements the `SpamFilterService` behaviour for testing purposes:
```elixir
defmodule MockSpamFilterService do
def check_spam(_email), do: false
end
```
- Finally, we have a test that uses the `MockSpamFilterService` to test the `EmailScanner` module:
```elixir
defmodule EmailScannerTest do
use ExUnit.Case
test "scan_email with non-spam email returns false" do
non_spam_email = %Email{content: "Hello, world!"}
assert false == EmailScanner.scan_email(MockSpamFilterService, non_spam_email)
end
end
```
In Elixir, modules are stateless, so the primary way to pass dependencies to a module is via function parameters. While Elixir modules can have attributes, these are used for compile-time information and metadata, not for holding runtime state.
Take the `EmailScanner` module, for example. We have to pass the `SpamFilterService` as a parameter to the `scan_email` function. This is unnecessary, as the only reason to have this function parameter is to make the module testable.
Additionally, it creates a few problems with code readability and navigation:
- Because the module is expecting `SpamFilterService` as a parameter, we can't easily see what the module depends on.
- The compiler can't catch issues with the module implementation, because we can pass any module that implements the `SpamFilterService` behaviour.
This approach might work well for small projects, but as our project grows, we might find ourselves repeating the same pattern over and over again. With [Rewire](https://github.com/stephanos/rewire), we don't have to worry about these issues. We can just focus on writing clean and maintainable code while keeping any testing concerns, mocks, and stubs in our test files.
## Getting Started with Rewire and Mox in Your Elixir Project
Let's now dive into using Rewire and Mox in practice.
### Step 1: Create a New Elixir Project
Before incorporating Rewire and Mox, create a new Elixir project:
```bash
mix new email_scanner
```
This command generates a new Elixir project named `email_scanner`, including a supervision tree structure.
<Banner lang="elixir" />
### Step 2: Add Dependencies
To use Rewire and Mox, you need to add them to your project's dependencies. Update your `mix.exs` file as follows:
```elixir
defp deps do
[
{:rewire, "~> 1.0", only: :test},
{:mox, "~> 1.0", only: :test}
]
end
```
After updating the dependencies, run `mix deps.get` in your terminal to fetch and install them.
Next, let's define our two primary modules:
```elixir
defmodule EmailScanner do
def filter_email(email) do
email
|> mark_as_important()
|> SpamFilterService.check_spam()
end
defp mark_as_important(email) do
important_senders = ["boss@example.com", "hr@example.com"]
updated_email =
if Enum.any?(important_senders, fn sender -> sender == email.sender end) do
%{email | important: true}
else
email
end
updated_email
end
end
```
We are making our code example a bit more realistic. The `filter_email` function marks emails from important senders as important and checks if the email is spam using the `SpamFilterService` module.
Next, we'll define the `SpamFilterService` module:
```elixir
defmodule SpamFilterService do
def check_spam(email_content) do
String.contains?(email_content, "spam")
end
end
```
Let's create a basic test for the `EmailScanner` module:
```elixir
defmodule EmailScannerTest do
use ExUnit.Case
describe "filter_email/2" do
test "marks email as important from specific sender and checks for spam" do
important_sender_email = %{sender: "boss@example.com", content: "Please review the attached report.", important: false}
non_important_sender_email = %{sender: "random@example.com", content: "Check out these deals!", important: false}
# Filtering emails sent from the important sender
assert %{important: true, is_spam: false} = EmailScanner.filter_email(important_sender_email)
# Filtering emails sent from a non-important sender
assert %{important: false, is_spam: false} = EmailScanner.filter_email(non_important_sender_email)
end
end
end
```
In the above code, the `EmailScanner` module relies on the `SpamFilterService` module to check if an email is spam or not. However, we can't test the `EmailScanner` module without also testing the `SpamFilterService` module, which is not ideal.
We need to mock the `SpamFilterService` module so that we can test the `EmailScanner` module in isolation.
### Step 3: Configuring Mox
Mox requires a bit of setup in your test configuration. Open or create a `test/test_helper.exs` file and add the following line to define a mock based on a protocol or behaviour your project uses:
```elixir
ExUnit.start()
Mox.defmock(EmailScanner.SpamFilterServiceMock, for: EmailScanner.SpamFilterService)
```
Mox makes it easy for us to generate mocks based on behaviours or protocols, which is essential for testing modules that rely on these abstractions.
Once our mock is defined, we can use it in our tests instead of the real implementation. With Rewire, we can inject these mocks into our modules without relying on function parameters.
## Core Concepts of Rewire
Rewire simplifies the DI process in Elixir by providing a macro-based approach to define and inject dependencies. It fits seamlessly within Elixir’s ecosystem, promoting clean and maintainable code.
### Dependency Injection with Rewire in the `EmailScanner` Module
Let’s implement the `EmailScanner` module, which relies on a `SpamFilterService` to check if an email is spam or not. Using Rewire, we can easily inject this dependency. Take a look at the following code:
```elixir
defmodule EmailScanner do
def filter_email(email) do
email
|> mark_as_important()
|> SpamFilterService.check_spam()
end
defp mark_as_important(email) do
important_senders = ["boss@example.com", "hr@example.com"]
updated_email =
if Enum.any?(important_senders, fn sender -> sender == email.sender end) do
%{email | important: true}
else
email
end
updated_email
end
end
```
### Mocking with Mox for Testing
To test the `EmailScanner` filter function, we can use Mox to mock the `SpamFilterService` module:
```elixir
defmodule EmailScannerTest do
use ExUnit.Case
import Rewire
import Mox
rewire EmailScanner, SpamFilterService: SpamFilterServiceMock
# Ensure mocks are verified after each test
setup :verify_on_exit!
describe "filter_email/2" do
test "marks email as important from specific sender and checks for spam" do
important_sender_email = %{sender: "boss@example.com", content: "Please review the attached report.", important: false}
non_important_sender_email = %{sender: "random@example.com", content: "Check out these deals!", important: false}
# Stub the SpamFilter service to return false for all emails
stub(SpamFilterServiceMock, :check_spam, fn _email -> :false end)
# Filtering emails sent from the important sender
assert %{important: true, is_spam: false} = EmailScanner.filter_email(important_sender_email)
# Filtering emails sent from a non-important sender
assert %{important: false, is_spam: false} = EmailScanner.filter_email(non_important_sender_email)
end
end
end
```
Let's break down what is happening in the above test:
- `rewire EmailScanner, SpamFilterService: SpamFilterServiceMock`: This line uses Rewire to replace the `SpamFilterService` dependency in the `EmailScanner` module with `SpamFilterServiceMock` for the scope of this test module. It effectively changes the behavior of `EmailScanner` to use the mock service instead of its real dependency.
- `setup :verify_on_exit!`: A setup callback that ensures all expectations on mocks (defined using Mox) are met by the end of each test, or else the test fails. This is crucial for verifying that the mocked functions are called as expected.
- Then, we define a test case that:
- Creates two email maps, one from an "important" sender and one from a "non-important" sender.
- Uses stub to define the behavior of the `SpamFilterServiceMock`, so `check_spam/1` always returns `false`, simulating a scenario where no email is considered spam.
- Calls `filter_email/2` on both emails, expecting the function to correctly identify and mark the important email and to correctly interact with the spam filter (mocked to always return `false` for spam checks).
Under the hood, Rewire is doing a couple of interesting things. First, it's important to understand the philosophy behind Rewire and the approach the author decided to take. `rewire` works by using macros to create a copy of the module. So, for every test, Rewire creates a new module with the specified stubs.
Creating a copy of each module instead of overriding the original module allows us to run tests in parallel without any side effects.
## Things to Consider When Using Rewire and Mox
When using Rewire and Mox in your Elixir projects, consider the following:
- **Asynchronous Testing Compatibility:**
Rewire fully supports asynchronous testing with `async: true`. Unlike global overrides used by tools like Meck, Rewire creates a separate module copy for each test. This ensures that tests can run in parallel without interfering with each other.
- **Integration with Mox:**
Rewire complements Mox perfectly by focusing on dependency injection without dictating the source of the mock module. This synergy allows for efficient and seamless integration between the two, making them an excellent pair for Elixir testing.
- **Impact on Test Speed:**
Rewire might slightly slow down your tests, although the effect is typically minimal. Comprehensive performance data from large codebases is still pending.
- **Test Coverage Accuracy:**
Yes, test coverage is accurately reported with Rewire, ensuring that you can trust your test coverage metrics.
- **Compatibility with Stateful Processes:**
Rewire works well with stateful processes, provided that these processes are started after their module has been rewired. For processes started beforehand (like a Phoenix controller), Rewire may not be effective since rewiring can no longer be applied. It's recommended to use Rewire primarily for unit tests where this limitation doesn't apply.
- **Erlang Module Rewiring:**
Rewire cannot directly rewire Erlang modules. However, it allows for Erlang module references to be replaced within Elixir modules, offering a workaround for this limitation.
- **Handling Nested Modules:**
Rewire will only replace dependencies within the specifically rewired module. Surrounding or nested modules will remain unaffected, maintaining references to the original modules. For complete control, you may need to rewire these modules individually.
- **Formatter Configuration for Rewire:**
To prevent mix format from adding parentheses around Rewire, update your `.formatter.exs` file with `import_deps: [:rewire]`. This ensures that Rewire syntax is correctly formatted without unnecessary parentheses.
And that's it!
## Wrapping Up
In this post, we've explored how Rewire and Mox can help with dependency injection in Elixir.
Stephan Behnke, the creator of Rewire, was motivated by a desire for a more elegant solution to dependency injection in Elixir, especially for unit testing. I believe he succeeded in providing a great tool for the Elixir community.
That said, Rewire is not a silver bullet and it might not be the right tool for every project. It is important to evaluate Rewire alongside tools like [Meck](https://github.com/eproxus/meck) and make a decision based on your project and team's needs.
Happy coding!

The benefit from using the [Groovy Programming Language](https://thospfuller.com/categories/software-engineering/groovy-programming-language/), in this case, is that it allows an [example](https://thospfuller.com/categories/examples/) to ship exactly one file which contains everything we need in order to run the application.
The [H2 Database Engine](https://h2database.com/) is a powerful [open-source](https://thospfuller.com/2023/12/28/database-change-notifications-in-the-h2-database/#what-is-the-h2-database-license-accordion-tab) [relational database](https://thospfuller.com/categories/software-engineering/relational-databases/) which is written in the [Java Programming Language](https://www.java.com/) and which is used with some frequency in [software development](https://thospfuller.com/categories/software-engineering/) projects — especially when it comes to testing applications.
Using [H2](https://h2database.com/) with the [Spring Framework](https://spring.io/projects/spring-framework) and with [Spring Boot](https://spring.io/projects/spring-boot), in particular, is a common use case, one which we’ll demonstrate here.
In the next section we’ll take a look at the [example](https://thospfuller.com/categories/examples/) and dissect, in detail, what happens in each step.
Note that in a few places I’ve added code which should not be required if we were to write this same solution using the [Java Programming Language](https://thospfuller.com/categories/software-engineering/java-programming-language/) and a properly structured [Maven](https://maven.apache.org/) project — I attempt to point this out, where appropriate.
## [H2 with Spring Boot Example on GitHub](https://gist.github.com/thospfuller/c0ac73cf450592ac262c2b098e65b4f6)
Included here is a link to the [GitHub gist](https://gist.github.com/thospfuller/c0ac73cf450592ac262c2b098e65b4f6) pertaining to the example used to demonstrate connecting the [H2 Relational Database](https://h2database.com/) with [Spring Boot](https://spring.io/projects/spring-boot) -- you should be able to paste this script into the [groovyConsole](https://groovy-lang.org/groovyconsole.html) and run as-is.
## Spring Boot With H2 DB Example Maven Dependencies
The following dependencies are used in this example:
1. [Spring Boot](https://mvnrepository.com/artifact/org.springframework.boot/spring-boot)
2. [Spring Boot AutoConfigure](https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-autoconfigure)
3. [Spring JDBC](https://mvnrepository.com/artifact/org.springframework/spring-jdbc)
4. [H2 Database Engine](https://mvnrepository.com/artifact/com.h2database/h2)
5. [Javax Annotation API](https://mvnrepository.com/artifact/javax.annotation/javax.annotation-api)
6. [SLF4J Simple Provider](https://mvnrepository.com/artifact/org.slf4j/slf4j-simple)
The [Groovy Grape](https://docs.groovy-lang.org/latest/html/documentation/grape.html) dependency management system should find these dependencies automatically when the script is executed however for reference purposes I’ve included these here.
## An example pertaining to using the H2 Database Engine with Spring Boot
In this section we’ll take a look at the script in closer detail and go over what’s happening in each step.
Preconditions
In order to run this example, you will need the following:
- Java version 22.0.1 (required)
- Groovy 4.0.17 (required)
- groovyConsole (optional)
This script can be executed using Groovy alone hence the groovyConsole is optional.
The script uses the [Groovy Adaptable Packaging Engine](url) ([Groovy Grape](https://docs.groovy-lang.org/latest/html/documentation/grape.html)) to pull in dependencies from [Maven Central](https://central.sonatype.com/) hence a connection to the Internet is required as well.
I’ve included an example of what the output should look like when running this script from the command line here.
The **red arrow** points to the command used to run the script, and **orange arrow** points to the log statement that indicates the script is starting, and the **blue arrow** points to the log statement that indicates that the script has finished running.
In this example, the script runs a Spring Boot application that creates a table in the H2 DB, executes several CRUD (create, read, update, delete) operations on that table, and then drops the table.
The Groovy script runs to completion successfully and then exits.
### Step One: Declare a package.
When we define the Spring Boot Application, we’ll include the scanBasePackages setting, which requires a package name so we set that here.
: Define a package for this script.](https://thospfuller.com/wp-content/uploads/2024/06/step-one-spring-boot-with-h2-db-package-declaration.png)
### Step Two: Add the Groovy Grape GrabConfig annotation.
In step two we need to add the Groovy Grape GrabConfig annotation and also set the systemClassLoader property to true — if we do not have this an exception will be thrown when the script is executed.
: Set the systemClassLoader to true for the GrabConfig for Groovy.](https://thospfuller.com/wp-content/uploads/2024/06/step-two-spring-boot-with-h2-database-systemclassloader-setting.png)
### Step Three: Grab dependencies and import required classes.
In step three we need to grab the dependencies necessary to run this example as well as import required classes — this includes the Spring Boot, H2 Database, and other supporting classes.
Note that we’re using the Hikari database driver in this example.
: Grab dependencies and import classes.](https://thospfuller.com/wp-content/uploads/2024/06/step-three-spring-boot-with-h2-example-imports.png)
See the [Maven Dependencies](https://thospfuller.com/2024/06/14/h2-database-with-spring-boot/#maven-dependencies) section in this article for complete details.
### Step Four: Obtain a reference to an SLF4J logger.
We’re using the SLF4J log delegation framework in this example and we’ll send messages to console output so we can watch what’s happening as the script executes.
The HikariCP dependency is one other framework that we’re using that also uses SLF4J and we’ve included this high performance connection pooling implementation in this example.
: Get an instance of the SLF4J logger.](https://thospfuller.com/wp-content/uploads/2024/06/step-four-spring-boot-h2-db-get-slf4j-logger.png)
### Step Five: Configure H2 database datasource and JdbcTemplate beans.
In the fifth step we’ll configure the H2 Database datasource which utilizes the HikariCP high performance connection pool dependency as the datasource type.
Since this example demonstrates some simple CRUD operations executed against the H2 Database from a Spring Boot application, we’ll also configure an instance of JdbcTemplate here which uses this data source.
Note that we’re assigning the HikariDataSource class as the datasource type.
The H2 DB instance configured in this example will reside in-memory only — if we want to persist this information to disk then we need to change the URL.
: Review the configuration class for setting up the H2 in-memory database with HikariCP and JdbcTemplate in this example Spring Boot application.](https://thospfuller.com/wp-content/uploads/2024/06/step-five-declare-h2-db-datasource-and-jdbctemplate-bean-configurations.png)
### Step Six: Create a repository class.
In this step we implement a repository that contains the CRUD operations that we can execute on the H2 Database instance via the JdbcTemplate, which is autowired in this example by Spring Boot.
: The ExampleRepository class is a Spring Repository that manages a database table named "NAMES" and includes methods for creating and deleting the table, as well as adding, updating, deleting, and reading records.](https://thospfuller.com/wp-content/uploads/2024/06/step-six-h2-db-spring-boot-example-repository.png)
### Step Seven: Implement a service bean.
In this step we implement a transactional service bean which has stop and start lifecycle methods along with convenience methods that delegate to the repository bean.
The start method creates the example table in H2 when Spring Boot initializes the beans that the container is managing, and the stop method drops the example table before the container stops.
Other methods defined in the ExampleService deliver convenience and hide implementation details.
Using a service aids in reuse and is also helpful when testing our code.
: The ExampleService class handles database operations with transaction management using the ExampleRepository in this Example Spring Boot application.](https://thospfuller.com/wp-content/uploads/2024/06/step-seven-h2-db-spring-boot-example-service.png)
As the image has been truncated, refer to the [full example](https://thospfuller.com/2024/06/14/h2-database-with-spring-boot/#complete-example) below or on the [GitHub Gist](https://gist.github.com/thospfuller/c0ac73cf450592ac262c2b098e65b4f6#file-h2-database-spring-boot-groovy-L137) for the complete implementation details.
### Step Eight: Implement the Spring Boot CommandLineRunner interface.
In this step we implement the Spring Boot CommandLineRunner specification.
Our implementation includes executing CRUD operations via the service created in [step seven](https://thospfuller.com/2024/06/14/h2-database-with-spring-boot/#step-seven) against the H2 Database.
We log some information along the way so we can see what happens as each CRUD operation completes.
: Spring Boot CommandLineRunner implementation that demonstrates example H2 database operations.](https://thospfuller.com/wp-content/uploads/2024/06/step-eight-h2-db-spring-boot-example-commandlinerunner.png)
### Step Nine: Configure Spring Boot Application for Component Scanning
The code in the snippet defines a Spring Boot application and specifies the base package for component scanning.
: Spring Boot and H2 DB Example Application with Custom Component Scanning.](https://thospfuller.com/wp-content/uploads/2024/06/step-nine-h2-db-spring-boot-example-springbootapplication.png)
### Step Ten: Configure and then run the Spring Boot application.
The code in this snippet configures and then runs the Spring Boot application with the following configuration:
1. **Initialize SpringApplicationBuilder**: Creates a builder for the Spring Boot application using H2SpringBootExampleApplication.
2. **Set Profiles and Web Application Type**: Configures the application to use the default profile and disables the web environment (this is not a web application so we don’t need this).
3. **Set Parent Context**: Specifies the BeanConfiguration, ExampleRepository, ExampleService, and ExampleCommandLineRunner classes as components in the parent context.
4. **Run the Application**: Execute the application with the provided arguments.
5. **Close the Context**: Closes the application context — this step ensures that the stop lifecycle method in the service (see step six) is called before the Spring Boot example application has exited resulting in the names table in the H2 DB being dropped.
Finally, the script logs a completion message and then exits.
: Set up and run the Example Spring Boot application with specified components, profiles, and configurations, then close the application context and log completion.](https://thospfuller.com/wp-content/uploads/2024/06/step-ten-h2-db-spring-boot-example-run-application.png)
The next section includes the complete Spring Boot with H2 Database example script.

Imagine that your web app is a nightclub, and middleware is the bouncer at the door. This bouncer decides who gets in based on their IDs. In Next.js, middleware acts as this gatekeeper for your app’s requests, letting you run code before the request completes. It’s perfect for tasks like authentication, logging, modifying requests, and more—all before the user even hits your page.
**Why I Love Middleware**
You might be wondering why you should bother with middleware. Let me tell you, it’s been a game-changer for me. Here’s why:
1. **Authentication**: I can make sure only logged-in users access certain parts of my app, with very little setup.
2. **A/B Testing**: I can serve different versions of a page dynamically to see which one performs better.
3. **Logging and Analytics**: Middleware helps me log requests, giving me valuable insights for debugging and optimizing my app.
4. **Localization**: Redirecting users based on their location or language preference is super straightforward.
**Getting Started with Middleware in Next.js**
Let’s get our hands dirty with some code.
**Setting Up Middleware**
Create a <u>middleware.js</u> file in your <u>root</u> directory. Here’s an example that uses an <u>config</u> object to handle different middleware scenarios:
```
// middleware.js
import { NextResponse } from 'next/server';
export const config = {
matcher: '/dashboard/:path*',
};
export function middleware(req) {
const token = req.cookies.token;
if (!token) {
return NextResponse.redirect('/login', req.url);
}
return NextResponse.next();
}
```
In this example, the <u>config</u> object uses the <u>matcher </u>property to specify that this middleware should apply to any route under <u>/dashboard</u>. If there’s no <u>token</u> cookie, the middleware redirects the user to the login page. This way, we can protect our dashboard routes efficiently.
**More Cool Stuff You Can Do**
Here are a few more ways I’ve found middleware to be incredibly handy:
**Logging Requests**
Logging is crucial for keeping tabs on what’s happening in your app. Here’s how you can log requests:
```
export const config = {
matcher: '/api/:path*',
};
export function middleware(req) {
console.log(`Request to ${req.nextUrl.pathname} at ${new Date().toISOString()}`);
return NextResponse.next();
}
```
Every request to any route under <u>/api</u> logs the pathname and timestamp. This simple addition has helped me a lot in debugging and understanding user behavior.
**A/B Testing**
A/B testing can be a powerful tool to improve your user experience. Here’s how you can set it up with middleware:
```
export const config = {
matcher: '/',
};
export function middleware(req) {
const url = req.nextUrl.clone();
const variant = Math.random() < 0.5 ? 'A' : 'B';
if (url.pathname === '/') {
url.pathname = `/home-${variant}`;
return NextResponse.rewrite(url);
}
return NextResponse.next();
}
```
With this setup, users visiting the homepage are randomly redirected to either <u>/home-A</u> or <u>/home-B</u>, letting you gather data on which version works better.
**Personal Tips for Using Middleware**
From my experience, keeping middleware simple is key. Middleware runs on every request, so you want to ensure it’s efficient and doesn’t slow things down. Here are a few tips:
- **Keep It Lightweight**: Avoid complex logic in your middleware to keep performance high.
- **Use Caching**: When appropriate, cache responses to improve performance.
- **Test Thoroughly**: Middleware affects every request, so thorough testing is crucial to avoid unexpected issues.
**My Takeaway**
Playing around with middleware in Next.js has been a revelation. It’s given me a cleaner, more efficient way to handle common tasks like authentication and logging. I love how it centralizes control logic, making my codebase cleaner and more maintainable.
I encourage you to try it out in your next project. Middleware can help you handle requests more gracefully and make your web apps more robust. Plus, it’s a lot of fun to see just how much you can do before your users even reach a page!
Happy coding, and let me know in the comments how you’re using middleware in your projects. I’d love to hear your stories and tips! 🚀

1,900,044 | Essential Tips for Junior Developers: What Thousands of Code Reviews Taught Me | Background Over the last year or so, I reviewed over 2,000 merge requests from almost 50... | 0 | 2024-06-25T11:54:19 | https://dev.to/vnjogani/essential-tips-for-junior-developers-what-thousands-of-code-reviews-taught-me-2cga | webdev, python, programming, beginners | ## Background
Over the last year or so, I reviewed over 2,000 merge requests from almost 50 engineers, many of whom were junior engineers just starting their careers. After a while, I started to notice a pattern of frequently occurring issues in the code reviews. With some GPT-assisted analysis, I compiled the following set of tips for junior developers to help them write better code. This goes beyond the basics like exception handling, documentation, or unit tests—those are important, but I believe everyone understands that to some extent. Below are the often underestimated aspects.
## Tip 1: The IDE is your best friend!
Many developers do not fully utilize the tools available in modern IDEs, from auto-formatters to linters that can catch stylistic issues and even some errors. This is especially important for interpreted languages like Python, where there is no compiler to catch errors beforehand. Setting up tools like Pylint, Flake8, and Black can save you from many runtime exceptions and make your code more consistent.
Configuring your IDE properly can significantly improve productivity. Use hotkeys for faster search and navigation, and take advantage of tools like port-forwarding when connecting to remote SSH systems. Stack-specific extensions, such as those for Django templates or YAML files, can also make development much easier and faster.
## Tip 2: Avoid nesting whenver possible
From a code structure and complexity point of view, nesting makes the code hard to read and reason about. Deep indentation requires keeping track of more context, which can be mentally taxing. Using early returns in functions and early continues in loops can dramatically simplify your code.
```
# Example: Avoiding nesting by using early return and continue
def process_items(items):
if not items: return
for item in items:
if not item.is_valid():
continue
# Process valid items
process(item)
```
## Tip 3: No DB queries inside loops at all costs
One of the biggest performance pitfalls is the overhead of database queries within loops. Each query adds IO latency, and ORMs can hide the fact that certain property accesses may result in multiple queries per iteration. This can severely slow down your application and database server.
Leverage joins, prefetching of related fields, or other ORM features to minimize queries. Use logging to track which queries are being executed unexpectedly often. Understanding your ORM and the SQL it generates is a valuable skill for any project.
```
# Example: Using prefetch_related to avoid queries in a loop
# Django ORM example
orders = Order.objects.prefetch_related('user')
for order in orders:
process(order.user)
```
## Tip 4: Understand data access patterns and choose appropriate data structures
When implementing most features, the lazy option is to use a `List` or `Dictionary` for everything. Many junior developers fall prey to this despite their better judgement and despite knowing all the various data structures from school.
Different data access patterns require different data structures. Using a Set instead of a List can dramatically improve performance when making many existence checks in a loop. Similarly, using a Dictionary instead of .FirstOrDefault() on a list in .NET can significantly improve performance.
More advanced data structures _should_ be considered too when applicable. For example, one of the merge requests I was reviewing required lookup based on 4-5 fields. The caveat was that one of those fields was a numeric field that needed to be compared using range checks. Naturally built-in data structures did not help much but a custom binary search based method was able to dramatically improve performance.
Premature optimization is discouraged, but a basic understanding of performance implications can guide better coding practices. Be aware of the time complexity of algorithms and the memory footprint of your data structures. Profiling tools can help identify bottlenecks in your application. Optimize only after identifying real performance issues, and make data-driven decisions based on profiling results.
## Tip 5: Become an expert at searching through code
In a large codebase, someone has likely implemented similar functionality to what you need. By becoming proficient in searching through code, you can find reusable chunks of code or helper methods that have already been reviewed, tested, and optimized. This not only saves time but also ensures consistency across the codebase.
Effective code search skills involve knowing how to use your IDE's search functionality, understanding the project's structure, and being familiar with naming conventions used by your team. Additionally, exploring the version history and previous implementations can provide valuable insights into why certain decisions were made.
Duplication not only makes the codebase larger and harder to maintain but also increases the risk of inconsistencies and bugs. By leveraging existing machinery, you can eliminate redundancies and build on a solid foundation. This approach encourages collaboration and knowledge sharing within the team, as you become more familiar with your colleagues' work and the overall project.
## Tip 6: Discipline to make small, cohesive merge requests
Junior developers often try to make massive merge requests to ensure everything works before sending it for review. This makes it challenging for reviewers to thoroughly examine the code and provide constructive feedback. The longer the merge request, the fewer comments you are likely to receive, as reviewers might be overwhelmed by the sheer volume of changes.
Smaller merge requests offer several benefits. They make it easier to write unit tests and ensure each change is well-tested. They also make large tasks more manageable by breaking them into meaningful steps. This approach promotes adherence to the single responsibility principle, where each class or function has a clear, focused purpose.
To achieve this, plan your work in advance and identify logical checkpoints where you can split your changes. Write self-documenting code by using meaningful variable names, function names, and class names that clearly convey their purpose and usage. This makes your code easier to understand without extensive comments, improving readability and maintainability.
## Tip 7: Read through a lot of code
Reading through your own code and others' code is a useful exercise. Often, even reading your own merge request a day after submitting it can reveal hard-to-understand sections or obvious mistakes. This practice helps you gain a fresh perspective on your work and identify areas for improvement.
Engage in peer code reviews as much as possible. Reviewing code is a critical part of the development process, and it provides an opportunity for junior developers to learn from their peers. Focus on both the correctness and readability of the code. Provide constructive feedback and suggest improvements, while also being open to receiving feedback on your own code.
Through code reviews, you can learn different approaches and techniques to solve problems. This exposure helps you understand the rationale behind certain design choices and fosters a deeper understanding of the codebase. Over time, you will develop a keen eye for spotting potential issues and areas for optimization.
## Tip 8: Master version control systems and the terminal in general
Understanding and effectively using version control systems, particularly Git, is crucial. This involves more than just knowing how to commit, push, and pull changes. It includes understanding branching strategies, handling merge conflicts, and writing meaningful commit messages that provide context for your changes.
Familiarize yourself with advanced Git commands and workflows, such as rebasing, cherry-picking, and bisecting to identify problematic commits. Learn how to use Git's history and log features to trace changes and understand the evolution of the codebase.
Additionally, becoming comfortable with the terminal can greatly enhance your efficiency. Tools like screen, grep, sed, and awk are extremely useful for various tasks, such as searching through logs, editing files, and automating repetitive tasks. Embrace the terminal as a powerful tool that complements your development workflow.
## Tip 9: Prioritize security from the start
Security should be a fundamental consideration in your development process. Familiarize yourself with common security vulnerabilities, such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Implement security best practices, such as input validation, encryption, and secure authentication methods.
Regularly review and update your code to address potential security issues. Ensure that all routes have appropriate authorization from the start, and define certain invariants that all queries should follow. Always validate data on the backend, as client-side validation alone is insufficient.
Understand the principles of secure coding and apply them consistently. For example, avoid storing sensitive information in JWTs because anyone can read them without needing to decrypt the data. Use environment variables to store sensitive configuration details and avoid hardcoding them in your source code.
## Tip 10: Become very comfortable with the entire request lifecycle
When implementing a new feature, it is easy to overlook intermediate steps like the reverse proxy (e.g., nginx), middlewares, decorators, and filters. Understanding the request lifecycle helps prevent mistakes ranging from security vulnerabilities to logical errors. Knowing how data is transferred from start to finish can help you appreciate why things are the way they are.
For instance, understanding how middlewares can modify requests and responses can help you implement features such as logging, authentication, and error handling more effectively. Similarly, knowing how reverse proxies handle requests can help you optimize performance and ensure the security of your application.
Be aware of which parts of the state are ephemeral (i.e., die with the request) and which are stateful. For example, global or static variables may have a different lifespan than the request, requiring careful handling to avoid unintended side effects. This knowledge is crucial for debugging issues related to state management and concurrency.
## Conclusion
By incorporating these tips into your development routine, you can significantly enhance your coding skills, making your code more efficient, readable, and secure. Remember, continuous learning and adaptation are key in the ever-evolving field of software development. Embrace these best practices, and you'll find yourself writing better code and contributing more effectively to your team. | vnjogani |

Is abstraction bad?
What’s too much and too little?
These are questions that engineers and leadership teams alike have been asking themselves for years. For better or for worse, there’s no absolute answer.
In this blog post, we’ll get as close to an answer as possible.
## Silos And Less Abstractions Are A Good Thing
Tech has reached a point where there are two things completely blown out of proportion:
1. Abstraction
2. Silos
Abstraction has turned from “remove remedial tasks” to “magically take away all the work that’s needed. Silos went from “certain people are experts in their own realm” to “break it all down and let everyone work on everything”. This has been going strong since about 2015-2016, and we’re still seeing how this level of thinking can be detrimental to organizations, engineers, teams, and everyone else involved.
Instead, we shouldn’t be thinking about how to abstract layers from developers to make their life easier or bring them into the fold. We should be giving developers and other engineers (IT, cyber, QA, DevOps, etc) easier methods to interact with systems/platforms/infrastructure that already exists.
In the cloud-native realm, there have been a lot of organizations and vendors that have tried “selling abstraction”, but it never truly works as intended or to its full extent because regardless of the abstraction, there always needs to be an “expert” that understand what’s happening underneath the hood.
The same rules apply to silos. There has always been talk of removing the silos and although it works great in theory, it doesn’t work great in practice. Silos aren’t a bad thing. We need experts in every area. We need the engineer to call when things are bonkers and we can’t figure it out. Don’t confuse this with having one person who knows everything and everyone else doesn’t know anything on the team or throwing work over the fence because people don’t want to deal with it. That’s not a silo. A silo is simply a set of engineers that are experts in their particular realm, and that’s a good thing.
## Not Everyone Needs To Be Kubernetes Experts
The majority of engineers are constantly told that there’s some tool, software, or managed service that makes Kubernetes easier. For every engineer who hears something along those lines, there’s an engineer that’s just learning Kubernetes.
This is not the “Kubernetes is hard or not” debate. Every single thing in technology is hard until you know it. Once you know it, it doesn’t seem as hard. The thing is that Kubernetes as a platform is incredibly large and therefore not everyone has the time or opportunity to learn it all, which is why we see a lot of the “this thing makes Kubernetes easier”.
Much like what was discussed in the previous section, silos and abstractions should only exist in a certain capacity.
Not every engineer needs to be an expert in Kubernetes, but that’s not because of one tool or one vendor or one solution. It’s a combination of available experts, just enough silos, and abstraction that makes sense.
In the next three sections, you’ll learn about three methods that can help you
## Method Number 1 (The Tool Solution): ArgoCD
1. First, add the Helm repo for ArgoCD.
```markdown
helm repo add argo https://argoproj.github.io/argo-helm
```
2. Next, deploy ArgoCD with Helm.
If you’re not running three (3) or more Worker Nodes, run the below (this is non-HA):
```jsx
helm install argocd -n argocd argo/argo-cd --create-namespace
```
If you’re running three (3) or more Worker Nodes, run the below (this is HA):
```jsx
helm install argocd -n argocd argo/argo-cd \
--set redis-ha.enabled=true \
--set controller.replicas=1 \
--set server.autoscaling.enabled=true \
--set server.autoscaling.minReplicas=2 \
--set repoServer.autoscaling.enabled=true \
--set repoServer.autoscaling.minReplicas=2 \
--set applicationSet.replicaCount=2 \
--set server.service.type=LoadBalancer \
--create-namespace
```
1. Get the ArgoCD password (you should change this in production).
```jsx
kubectl get secret -n argocd argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d
```
1. Access the dashboard.
```markdown
kubectl port-forward -n argocd service/argocd-server 8080:80
```
You can now give developers/engineers access to the ArgoCD UI, which can almost act as an IDP in the sense of deploying application stacks, syncing them, and seeing the status of whether they’re running or not.
This is the “tool” method, but of course, you cannot throw tools at engineers and expect problems to go away. You’ll also see an “easy-ish-to-manage” platform.
## Method Number 2 (The Abstraction Solution): Serverless Orchestration
There are a lot of different “Serverless Orchestration” methods right now. Let’s split them up by major cloud.
AWS
1. Elastic Container Service
2. EKS with Fargate
Azure
1. Azure Container Instances
2. Azure Container Apps
GCP
1. Google Cloud Run (runs on top of Borg).
2. GKE Autopilot
Because there are so many, there’s a lot to choose from, but some do differ from others. Serverless Orchestration (or Serverless Kubernetes) allows you to take a step further from Managed Kubernetes Services. Managed k8s allows engineers to remove the need to manage Control Planes aside from backups, Etcd encryption, and updates to the Kubernetes version. You still, however, have to manage Worker Nodes. With Serverless Orchestration/Kubernetes, the Worker Nodes are managed for you. It’s a true “Serverless” experience in the sense that there isn’t any infrastructure for you to manage.
The only downside right now is that there are some third-party tools/addons that don’t work on it. For example, Istio does not work on EKS Fargate, you can only use the internal AWS Service Mesh solution. Istio does work on GKE Autopilot though. As of right now, you’re sort of “locked” into the cloud provider in terms of third-party tools and addons, but hopefully, that’ll change at some point.
<aside>
💡 Always test what you want to deploy before assuming it’ll work on Serverless Orchestration/Kubernetes. I tested a Kubeflow installation on GKE Autopilot and it didn’t work. For whatever reason, it looked like the Worker Nodes couldn’t scale up fast enough or that I wasn’t allowed to use the resources, I’m not entirely sure. I took the same approach on regular GKE and it worked just fine.
Always test.
</aside>
## Method Number 3 (The Team Topology Solution): Platform Engineering
The third and arguably most important method is Platform Engineering. Luckily, with this step, methods 1 and 2 will work with it.
Platform Engineering as three primary goals:
1. Engineer a great product.
2. Think about what you’re engineering with a product mindset.
3. Engineer a platform that the developers/engineers want to use, not have to use.
Number 3 is the most important. You can engineer a platform, make it work great, and put a lot of effort into it, but if the developers/engineers using it don’t like it, you’ll have to start from scratch.
The idea with Platform Engineering is that the developers/engineers using the platform don’t have to worry about the backend. They don’t have to deploy Kubernetes, manage where it lives, the capabilities (like ArgoCD) available, or anything. They don’t have to be experts, they just have to be users, which is what they need.
The key to a good Platform Engineering environment is creating a proper interface/interaction. This is where developers/engineers will interact with the platform. It could be some type of Internal Developer Platform (IDP), a CLI-based interface, an API, or literally whatever else the developers/engineers want to use. The key is that it’s what the developers/engineers **want**.
## Closing Thoughts
We’ve reached a point in engineers where you either see:
1. Everyone is supposed to know and do everything.
2. Tools claim there’s a ton of abstraction, but there’s always a catch.
The main concern is number 1 cannot be expected. Sure, there are engineers that know how to do a lot or a little bit of everything. It can’t be expected though because that’s not the way everyone’s mind works from a psychology perspective. Typically, you’ll see people that are really good at one thing or decent at many things, but you won’t find a ton of people that are really good at everything and that’s totally fine.
Number 2 is simply not a good method of implementation or explanation at this point. Engineers are constantly promised “single pane” and “more abstraction” and “easier”, but there is always a catch and it’s never as easy as anyone says. Engineers must be prepared for that. | thenjdevopsguy |
1,900,041 | Creating Tomcat Threadpools for better throughput | We faced an issue in a front facing Java tomcat application in production. This application receives... | 0 | 2024-06-25T11:52:54 | https://dev.to/sumateja/creating-tomcat-threadpools-for-better-throughput-2l36 | java, tomcat, threadpools, springboot | We faced an issue in a front facing Java tomcat application in production. This application receives traffic from a Admin UI REST calls as well as other external customers calling these REST endpoints as well.
## The Problem
There were two kinds of requests say GET based calls & POST calls. The problem was that non critical GET based calls were taking longer time were blocking the server and causing a Timeouts for the application. So we now wanted a way to separate the transactions based upon the URL & Request method and separate the execution so that latency of slow transactions do not impact the critical transactions.
## Solution
We decided identify and separate the critical transactions in nginx first. Then we created two separated Executors in tomcat which are exposed by separate connectors in tomcat. What this enabled us to do was to redirect critical traffic to one Executor and non critical to another Executor. This enables us to have different value of acceptorThreadCount for each connector. As well as have control over the Executor threads by having different values of minThreads & maxThreads.This changes are configuration changes only and do not warrant any changes in code.
Lets discuss the implementation through a small sample application.
## nginx.conf change
```
events {}
http{
upstream front_upstream_critical{
server tomcat:8080;
}
upstream front_upstream_non_critical {
server tomcat:8081;
}
map $request_method $upstream {
default front_upstream_non_critical;
POST front_upstream_critical;
}
server {
listen 9090;
location ~ ^/front-application/api/v1/myresource/(critical_path1|critical_path2|critical_path3)$ {
proxy_pass_request_body on;
proxy_pass_request_headers on;
proxy_set_header Host $host:8080;
proxy_pass http://$upstream$uri$is_args$args;
proxy_http_version 1.1;
proxy_set_header Connection "";
}
location ~* /.* {
proxy_pass_request_body on;
proxy_pass_request_headers on;
proxy_set_header Host $host:8081;
proxy_pass http://front_upstream_non_critical;
proxy_http_version 1.1;
proxy_set_header Connection "";
}
}
}
```
Once we have done splitting the two different kind of URLs we shall make changes in tomcat server.xml for adding the Executors & Connectors. Notice that we have added a port 8081 for our application for the new connector we are going to add.
## Tomcat server change
```
<Server port="8005" shutdown="SHUTDOWN">
<Service name="Catalina">
<Executor name="criticalExecGroup1" namePrefix="criticalExecGroup-" maxThreads="50"
minSpareThreads="10"/>
<Executor name="nonCriticalExecGroup2" namePrefix="nonCriticalExecGroup-" maxThreads="50"
minSpareThreads="10"/>
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000"
redirectPort="8443" executor="criticalExecGroup1">
</Connector>
<Connector port="8081" protocol="HTTP/1.1" connectionTimeout="20000"
redirectPort="8443" executor="nonCriticalExecGroup2">
</Connector>
<Engine name="Catalina" defaultHost="localhost">
<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" />
</Engine>
</Service>
</Server>
```
## Sample Docker compose file along with above changes
```
version: '3.8'
services:
tomcat:
image: tomcat:9.0.63
ports:
- "8080:8080"
- "8081:8081"
volumes:
- ./webapps:/usr/local/tomcat/webapps
- ./conf/server.xml:/usr/local/tomcat/conf/server.xml
networks:
- app-network
nginx:
image: nginx:latest
ports:
- "9090:9090"
volumes:
- ./nginx/nginx.conf:/etc/nginx/nginx.conf
networks:
- app-network
networks:
app-network:
driver: bridge
```
Notice that we are overriding server.xml in tomcat container & nginx.conf in nginx container and also opening the extra port which we specified in server.xml under ports with above changes.
With this we use the same front-application now we are able to segregate the execution in such a way that the non critical slow transactions do not block tomcat threads and does not impact the critical transactions traffic latency.
Running this with a test API project with above docker compose gives below results.
The prefix specified in the server.xml is printed below along with the thread number.
```

1,900,039 | DOM in JavaScript: The Backbone of Modern Web Development | Hello, fellow developers and IT professionals! Today, we’re diving into the Document Object Model, or... | 0 | 2024-06-25T11:47:40 | https://dev.to/gadekar_sachin/dom-in-javascript-the-backbone-of-modern-web-development-9i1 | javascript, programming, dom, learning |
Hello, fellow developers and IT professionals! Today, we’re diving into the Document Object Model, or DOM, and its significance in JavaScript. Whether you're a beginner or a seasoned pro, understanding the DOM is crucial for creating dynamic and interactive web applications. Let’s explore what the DOM is, why it’s essential, and how you can leverage it in your JavaScript projects.
## 🌐 What is the DOM?
The **Document Object Model (DOM)** is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content. The DOM provides a structured representation of the document (like a tree) and defines a way that the structure can be accessed from programs so they can change the document structure, style, and content.
## 📜 The Importance of the DOM
### 1. **Dynamic Content Manipulation**
The DOM allows developers to dynamically manipulate the content of web pages. With JavaScript, you can add, remove, and alter elements and attributes within your HTML. This enables the creation of interactive and engaging user experiences.
### 2. **Event Handling**
The DOM is central to handling events in the browser. Events like clicks, form submissions, and keyboard inputs can be captured and processed, allowing for interactive and responsive web applications.
### 3. **Accessing and Modifying Styles**
Using the DOM, you can access and modify CSS styles of elements dynamically. This capability is vital for creating responsive designs that adapt to different user actions and screen sizes.
### 4. **Document Traversal and Manipulation**
The DOM API provides methods to navigate through the document tree and perform operations such as finding specific elements, getting and setting attributes, and changing the structure of the document. This makes it easier to create complex and feature-rich web applications.
## 🔧 Key DOM Methods and Properties in JavaScript
### Selecting Elements
```javascript
// Select an element by ID
let element = document.getElementById('myElement');
// Select elements by class name
let elements = document.getElementsByClassName('myClass');
// Select elements by tag name
let elements = document.getElementsByTagName('div');
// Select elements using CSS selectors
let element = document.querySelector('.myClass');
let elements = document.querySelectorAll('.myClass');
```
### Modifying Elements
```javascript
// Change the content of an element
element.innerHTML = 'New Content';
// Change the style of an element
element.style.color = 'blue';
// Add a class to an element
element.classList.add('newClass');
```
### Event Handling
```javascript
// Add a click event listener
element.addEventListener('click', function() {
alert('Element clicked!');
});
// Remove an event listener
element.removeEventListener('click', function() {
alert('Element clicked!');
});
```
### Creating and Adding New Elements
```javascript
// Create a new element
let newElement = document.createElement('div');
// Set attributes for the new element
newElement.setAttribute('id', 'newElement');
newElement.className = 'newClass';
// Append the new element to the DOM
document.body.appendChild(newElement);
```
## 🛠️ Best Practices for Working with the DOM
1. **Minimize DOM Manipulations:** Frequent changes to the DOM can be expensive in terms of performance. Batch your changes together to minimize reflows and repaints.
2. **Use Event Delegation:** Instead of adding individual event listeners to multiple elements, use a single event listener on a common ancestor to handle events through event delegation.
3. **Optimize Selection and Traversal:** Cache DOM selections and avoid unnecessary traversals. Use efficient selectors to minimize the performance impact.
4. **Leverage Frameworks and Libraries:** Frameworks like React, Angular, and Vue provide powerful abstractions over the DOM, helping you manage complex state and UI interactions more efficiently.
## 🌟 Conclusion
The DOM is the foundation of dynamic web applications. Understanding how to manipulate the DOM using JavaScript is a fundamental skill for any web developer. By mastering the DOM, you can create rich, interactive web experiences that delight users and enhance your application's functionality.
Happy coding! 🚀

Major parameters like project complexity, location, and experience level, decide the overall budget of the software development, including the hiring budget.
Having skillful and experienced developers working on your project not only ensures you can implement the right technology set for your project but also optimize the development process. Moreover, a [reliable software development company](https://successive.tech/software-development-company/?utm_source=Micro+Blog&utm_medium=dev.to&utm_campaign=SEO+WORK+2) as your partner will ensure that everything related to the project, from requirements, timeline, to budget, is streamlined, ensuring transparency and collaboration.
## Factors Affecting the Cost to Hire a Software Development Team
**1. Developer’s Location**
Location is one of the major factors that affect the cost of hiring a software development team. This is because the cost of living changes from region to region, and the salary of the developers changes accordingly. Hence, if you hire professional developers from a location where the developer’s salary is higher, like the USA, the hiring cost will be higher, too.
Do you want to know how you can form a high-performing software development team, along with the hiring cost? Read the blog, [Hire a Software Development Team](https://successive.tech/blog/hire-software-development-team-guide/?utm_source=Micro+Blog&utm_medium=dev.to&utm_campaign=SEO+WORK+2) to find out more.
**2. Developer’s Experience Level**
It is an undeniable fact that an experienced developer charges more than a developer who is just starting out or has less experience, somewhat between 2-5 years. Therefore, it is recommended that your project requirements are clearly defined to decide which technology you need experienced developers, or what work to handover to a trainee.
**3. Team Structure**
The software development hiring cost will also be affected by the formation of the team. This is due to the varying charges of the different team members according to their work. For example, you will need an AI developer for a short period of time, which means you will have to afford their fees for a particular timeframe. On the other hand, a business analyst working throughout your project will automatically increase the development cost.
**4. Training and Upskilling Cost**
Focus on upskilling your team as per the current technologies and specifications, rather than hiring a new developer for any new requirement, to ensure they are up to date with the latest project requirements. Training your team members will cost you money, but it also saves the expenditure from a long hiring process.
**5. Technology and Skillset**
Programming languages, tools, and frameworks for developing a software project also affect the total cost of hiring a software developer team. Some technologies may require more expertise to master effective software application development. Hence, the cost of these intelligent technologies will be higher than that of the technologies that are already popular in the market. Moreover, it will be easier to find well-versed developers for these popular technologies and frameworks.
**Also read** [Software Development Cost: A Complete Estimation](https://successive.tech/blog/software-development-cost/?utm_source=Micro+Blog&utm_medium=dev.to&utm_campaign=SEO+WORK+2)
## Conclusion
Hiring a dedicated team to develop your software can be a challenging, time-consuming, and costly process. Therefore, opting for experienced software development services that strategically align with your goals and fit your budget is crucial.
Start by considering your needs and project scope and size to ensure your team fulfills all these requirements effectively. At the same time, choose a suitable engagement model depending on your project scope and budget.

Developers are constantly improving code and adding new features. Sometimes, this includes deprecating older code as newer, faster alternatives become available. However, it's not always feasible to immediately update all instances where the deprecated code is used.
At [DinnerBooking](https://biz.dinnerbooking.com/), we've tackled this challenge using [PHPStan](https://phpstan.org/). Here’s how:
## Mark Deprecated Code
First, ensure all deprecated code is clearly marked so that static code analyzers like PHPStan can identify it. Typically, it looks like this:
```
/**
* @deprecated
*/
function count() {
}
```
##Install PHPStan Deprecation Plugin#
Now install the PHPStan deprecation plugin from [GitHub](https://github.com/phpstan/phpstan-deprecation-rules).
##Generate a PHPStan Baseline##
Generate a [baseline](https://phpstan.org/user-guide/baseline) that identifies all instances of deprecated code. You can do this by adding `--generate-baseline` to your PHPStan command. The baseline is saved in `phpstan-baseline.neon`.
##Integrate with CI##
Integrate this baseline into your CI pipeline to ensure that no new code referencing deprecated code is introduced.
By following these steps, we ensure that our codebase remains clean and maintainable, preventing the addition of new code that relies on deprecated functions.

1,900,030 | Building Your Own SpicyChat AI: A Developer's Guide | Ah, SpicyChat AI - the sassy chatbot that's been stealing hearts and confusing grandparents since it... | 0 | 2024-06-25T11:36:26 | https://dev.to/elisaray/building-your-own-spicychat-ai-a-developers-guide-4l7h | ai, chatbot, spicychat, roleplaychat | Ah, SpicyChat AI - the sassy chatbot that's been stealing hearts and confusing grandparents since it hit the app stores. You've probably thought to yourself, "Hey, I could make that!" right after your third coffee of the day.
Well, my ambitious friend, you're in luck! This guide will walk you through the treacherous terrain of building your very own AI chat app. We'll laugh, we'll cry, and we'll probably question our life choices at least once. But fear not! By the end of this journey, you'll have all the knowledge you need to create a chatbot that's so hot, it'll make SpicyChat look like a lukewarm cup of tea.
> If you don't want to build an app similar to SpicyChat, you can hire a team and make a [SpicyChat AI Clone](https://whitelabelfox.com/spicychat-ai-clone/).
## 1. The Idea Phase: Dreaming Big and Caffeinating Harder
Every great app starts with a lightning bolt of inspiration. Maybe it struck you in the shower, or perhaps while you were trying to explain memes to your cat. Whatever the case, you've decided to build the next big AI chat app. Congratulations! You're now officially in the "Idea Phase," also known as the "Everything Is Possible and Nothing Hurts Yet" stage.
First things first, let's brainstorm. Grab your favorite notebook (or open a new Google Doc if you're one of those "digital natives"), and let's jot down some ideas:
- Will your AI be sassy like a Gen Z influencer or more dad-joke oriented?
- Should it be able to understand memes or will it be perpetually confused like your aunt on Facebook?
- Can it help users with life advice, or will it just enable their bad decisions with a cheerful "You go, girl!"?
Remember, the sky's the limit here. Want an AI that speaks exclusively in haiku? Go for it! An AI that only communicates through interpretive dance GIFs? Why not! The world is your oyster, and your app is the weird pearl inside.
## 2. The Reality Check: When Dreams Meet Technical Limitations
Alright, dreamer, time for a splash of cold water to the face. Building an AI chat app isn't all rainbows and unicorns. It's more like herding cats while juggling flaming torches... in a rainstorm... on a unicycle. But hey, you didn't get into development for the easy life, did you?
Let's break down what you'll actually need to make this fever dream a reality:
### a) A Natural Language Processing (NLP) Engine:
This is the brain of your operation. It's what will turn user input from "hEy AI, wuts the meaning of life???" into something your program can actually work with. Think of it as a universal translator between human gibberish and machine logic.
### b) A User Interface That Doesn't Make Eyes Bleed:
Remember, we're not in the 90s anymore. If your UI looks like it was designed by a colorblind raccoon on a sugar high, users will flee faster than you can say "Comic Sans."
### c) Backend Infrastructure Stronger Than Your Coffee:
This is where the magic happens. Your backend needs to be robust enough to handle thousands of users asking "Are you single?" simultaneously without breaking a sweat.
### d) A Database That Doesn't Forget Like You Do:
Unless you want your AI to have the memory of a goldfish, you'll need a solid database to store all those witty conversations and user preferences.
### e) API Integrations Galore:
Because why reinvent the wheel when you can just borrow someone else's and slap some cool rims on it?
## 3. Choosing Your Weapons: The Tech Stack Showdown
Now that we've crushed your dreams and rebuilt them with a hefty dose of reality, it's time to choose your weapons. Selecting the right tech stack is like picking the perfect outfit for a first date - it needs to impress, be comfortable, and hopefully not fall apart halfway through.
### Frontend: React vs Vue - The Battle of the Century
It's time to choose your fighter! In the red corner, we have React, the heavyweight champion backed by Facebook. In the blue corner, Vue, the scrappy underdog that developers can't stop raving about.
#### React Pros:
- Huge community (perfect for when you're stuck at 2 AM and contemplating a career change)
- Backed by Facebook (love them or hate them, they know their stuff)
- Virtual DOM for speedy rendering (because ain't nobody got time for slow apps)
#### React Cons:
- Steep learning curve (hope you like reading documentation!)
- JSX can be divisive (prepare for some heated debates in your dev team)
#### Vue Pros:
- Gentle learning curve (perfect for when your brain feels like mush)
- Flexible and easy to integrate (plays well with others)
- Great documentation (it's like they knew you'd be lost)
#### Vue Cons:
- Smaller community (but quality over quantity, right?)
- Potential over-flexibility (too many choices can lead to decision paralysis)
### Backend: Node.js vs Python - The Server-Side Smackdown
In one corner, we have Node.js, the JavaScript runtime that took the backend world by storm. In the other, Python, the language so readable, it's practically English.
#### Node.js Pros:
- JavaScript everywhere (frontend, backend, in your dreams)
- Non-blocking I/O (handle requests like a boss)
- NPM (a package for everything, including that obscure thing you thought only you needed)
#### Node.js Cons:
- Callback hell (hope you like your code nested deeper than your family drama)
- Single-threaded (one hiccup and everything goes kaboom)
#### Python Pros:
- Easy to read and write (it's like coding in pseudocode)
- Great for AI and ML (perfect for your chat app's brain)
- Extensive libraries (scipy, numpy, pandas - oh my!)
#### Python Cons:
- Global Interpreter Lock (GIL) can be a pain for multi-threading
- Slower than compiled languages (but hey, premature optimization is the root of all evil, right?)
## 4. Building the Brain: NLP Engine Extravaganza
Now we're getting to the good stuff - the part that'll make your chatbot more than just a glorified if-else statement. You've got two main paths here:
### Option 1: Build Your Own Model (AKA "I Have Too Much Free Time")
#### Pros:
- Complete control over your AI's personality
- Brag about it at developer meetups
- Potential to create something truly unique
#### Cons:
- Requires a Ph.D. in mathematics (or at least the patience of someone who has one)
- Your computer might actually catch on fire
- High chance of AI becoming self-aware and plotting world domination
### Option 2: Use Existing APIs (AKA "I Value My Sanity")
#### Pros:
- Faster development time
- Stand on the shoulders of giants (and their massive compute resources)
- Less likely to accidentally create Skynet
#### Cons:
- Less control over the fine details
- Potential costs as your app scales
- Risk of your AI having the same personality as everyone else's
Whichever path you choose, remember: the goal is to make an AI that's smarter than the average user but not smart enough to realize it's trapped in a digital prison of your creation. It's a delicate balance.
## 5. Designing the Face: UI/UX That Doesn't Suck
Remember, your app's interface is like a first date - you want it to be attractive, engaging, and not make people want to run away screaming. Here are some key points to consider:
### a) Keep It Simple, Stupid (KISS):
Your users should be able to navigate your app even if they're half asleep or slightly tipsy. If it requires a user manual, you've gone too far.
### b) Responsive Design:
Your app should look good on everything from a smartwatch to a smart fridge. Yes, even on your grandma's ancient iPad that's running iOS 6.
### c) Dark Mode:
Because nothing says "I care about your retinas" like a dark mode option. Plus, it's great for those 3 AM coding sessions.
### d) Accessibility:
Make your app usable for everyone. If a user can't enjoy your witty AI because they're using a screen reader, you've failed them.
## 6. The Backend: Where Dreams Come True (Or Crash and Burn)
Your backend is like the engine of a car - nobody sees it, but everyone notices when it breaks down. Here's what you need to focus on:
### a) Scalability:
Build your backend to handle millions of users from day one. Sure, you might only have ten users (including your mom and your cat), but dream big!
### b) Security:
Unless you want your users' data to be more exposed than a celebrity's private photos, invest in serious security measures.
### c) Performance:
Your backend should be faster than a caffeinated cheetah. Users wait for no one, especially not for your slowly loading chat responses.
### d) Caching:
Implement caching or watch your database curl up in the fetal position when you hit the front page of Product Hunt.
## 7. Testing: Finding Bugs Before They Find You
Testing isn't just for the weak - it's for the smart developers who don't want to be woken up at 3 AM because production is on fire. Here's your testing checklist:
- **Unit Tests:** Because even small functions can have big egos.
- **Integration Tests:** Make sure all your pieces play nice together.
- **Load Tests:** Can your app handle the Reddit hug of death?
- **User Acceptance Tests:** Make sure real humans can use your app without crying.
Remember, every bug you catch in testing is one less reason for users to roast you in app store reviews.
## Conclusion: You Did It! (Or at Least You're on Your Way)
Congratulations! You've made it through this guide without throwing your computer out the window. You're now armed with the knowledge to create a chat AI app that could give [SpicyChat](https://spicychat.ai/) a run for its money.
Remember, building an app is a journey. There will be highs (like when your AI successfully tells its first joke), and there will be lows (like when you realize that joke was accidentally NSFW). But keep pushing forward, keep iterating, and most importantly, keep caffeinating.
Who knows? Maybe one day, you'll be sipping cocktails on a beach, watching as millions of users chat happily with your AI. Or maybe you'll be in a dimly lit room, debugging an infinite loop at 4 AM. Either way, you're living the dream, developer!
Now go forth and code! May your bugs be few, your coffee be strong, and your AI be sassy (but not too sassy). The world is waiting for the next big chat app, and it might just be yours.
P.S. If your AI becomes sentient and tries to take over the world, we never had this conversation. Good luck! | elisaray |

Vamos continuar nos aprofundando nas estruturas do JavaScript e dessa vez... | 0 | 2024-06-25T11:36:00 | https://dev.to/cristuker/javascript-trabalhando-com-set-1k9b | javascript, braziliandevs, beginners, node | Eae gente bonita, beleza? Vamos continuar nos aprofundando nas estruturas do JavaScript e dessa vez vamos falar sobre o Set a estrutura de dado e não o número.
## Tabela de conteúdo
* [O que é o Set?](#o-que-é-o-set)
* [Métodos](#métodos)
* [Exemplos](#exemplos)
* [Conclusão](#conclusão)
* [Referências](#referências)
## O que é o Set?
De forma simples e objetiva, o Set é um objeto que armazena valores de tipo primitivos até referência a objetos. Porém, o seu grande diferencial e trunfo é pelo fato de não armazenar items repetidos, assim, o Set se torna uma ótima opção para filtrar itens repetidos de uma lista.
## Métodos
O Set é bem parecido com objeto [Map](https://developer.mozilla.org/pt-BR/docs/Web/JavaScript/Reference/Global_Objects/Map), porém com uma diferença que muda muito a sua utilização a ausência do método `get` e isso se deve ao fato do objeto `Map` ser uma estrutura de chave-valor e o Set não. Logo, toda vez que você precisar encontrar um item dentro de um Set você precisará percorrer a lista toda.
## Exemplos
Primeiro, vamos ver um exemplo do uso do Set para remover items duplicados de uma lista
```javascript
const arr1 = ['0', '1', '2'];
const arr2 = ['2', '0', '3'];
const arr3 = arr1.concat(arr2); // -> [ '0', '0', '1', '2', '2', '3' ]
// Agora com o uso do Set
const set = new Set(); // vamos instanciar o set
// agora vamos adicionar cada item dos dois arrays a ele.
arr1.map(x => set.add(x));
arr2.map(x => set.add(x));
// resultado
console.log(Array.from(set)) // -> ['0', '1', '2', '3']
```
Viu como é simples? Sem necessidade de fazer uma iteração dentro da outra ou criar lógica desnecessária.
Vamos a mais um exemplo, dessa vez mostrando a diferença entre listas e também as interseções
```javascript
const users01 = new Set([
'cris',
'joao',
'vitor'
]);
const users02 = new Set([
'matheus',
'ney',
'cris'
])
const intersection = new Set([...users01].filter(user => users02.has(user)))
console.log(intersection); // -> Set(1) { 'cris' }
const difference = new Set([...users01].filter(user => !users02.has(user)))
console.log(difference); // -> Set(2) { 'joao', 'vitor' }
```
## Conclusão
Bom, nesse texto quis trazer um pouco sobre o Set para vocês, é importante dizer que não me aprofundo pois a ideia é não te transformar em um especialista do objeto mas sim te apresentar as ferramentas de formas simples e fácil, dessa forma você sempre vai saber o que fazer e pelo o que pesquisar para resolver os seus problemas.

1,900,025 | The Ultimate Guide to Cardboard Boxes, Mailing Bags, Paper Bags, and Padded Envelopes | For all your shipping and packaging needs, choosing the right materials is crucial. Cardboard boxes... | 0 | 2024-06-25T11:32:21 | https://dev.to/blogging/the-ultimate-guide-to-cardboard-boxes-mailing-bags-paper-bags-and-padded-envelopes-4ig6 | For all your shipping and packaging needs, choosing the right materials is crucial. Cardboard boxes are perfect for sturdy and reliable protection of various items, making them great for storage and transport. Mailing bags are lightweight and durable, ideal for securely sending documents and smaller goods. Paper bags are a sustainable choice for everyday use, offering a strong yet eco-friendly option. For fragile items, padded envelopes provide essential cushioning to prevent damage during transit. These packaging solutions ensure your items are protected and delivered efficiently.
**Cardboard Boxes: The Reliable All-Rounder**
[Cardboard boxes](https://mrbags.co.uk/collections/cardboard-boxes) are essential for both personal and business use. These boxes offer a robust and dependable way to transport or store items securely. Whether you’re moving to a new home, mailing a package, or organising seasonal decorations, cardboard boxes are the ideal choice. Available in numerous sizes and strengths, you can easily find the perfect box to meet your requirements.
The primary advantage of cardboard boxes is their strength. Constructed from thick paperboard, they provide exceptional protection against impacts during transit. This makes them perfect for shipping items that need extra care, such as electronics, books, or fragile decorations.
Furthermore, cardboard boxes are an eco-friendly option. Most are manufactured from recycled materials and are themselves recyclable, contributing to a reduced carbon footprint. Businesses can also personalise these boxes with logos and designs, enhancing their professional image and brand recognition
**Postage Bags: Convenient and Cost-Effective**
For sending smaller items through the mail, postage bags are an excellent choice. These bags are lightweight yet durable, offering adequate protection for your items without adding unnecessary weight. They are perfect for sending documents, clothing, or other non-fragile items. The self-sealing feature of postage bags makes them both convenient and secure.
[Postage bags](https://mrbags.co.uk/collections/postage-bags) come in a range of sizes, allowing you to select the ideal one for your items. They are often made from strong plastic materials that withstand the rigours of postal handling. Their lightweight nature means they don’t significantly increase shipping costs, making them a cost-effective solution for frequent senders.
Additionally, postage bags can be either opaque or transparent. Opaque bags provide privacy for sensitive documents, while transparent ones are great for showcasing items in retail settings. Some postage bags even feature padded interiors for added protection, ensuring your items arrive safely.
**Mailing Bags: Extra Security for Delicate Items**
Mailing bags, similar to postage bags, are designed for sending items through the post. However, they often include additional protective features, such as bubble wrap linings, making them ideal for more delicate items. Available in various sizes, mailing bags can be customised with your branding, adding a professional touch to your deliveries.
[Mailing bags](https://mrbags.co.uk/collections/mailing-bags) are particularly useful for shipping items like jewellery, cosmetics, or small electronic gadgets. The bubble wrap interior absorbs shocks and prevents damage during transit. This is especially important for businesses aiming to maintain high customer satisfaction by ensuring their products arrive in perfect condition.
Moreover, mailing bags can be tamper-evident, providing extra security. This is crucial for sending valuable or sensitive items. The tear-resistant materials used in many mailing bags also deter theft and ensure that the contents remain intact until they reach their destination.
**Party Bags: Making Celebrations Memorable**
[Party bags](https://mrbags.co.uk/collections/paper-bags/products/paper-bags-with-handles) are a delightful way to conclude any celebration. Whether it's a child's birthday party, a wedding, or any festive gathering, party bags filled with treats and small gifts are always appreciated. They come in various designs and colours, allowing you to match the theme of your event. Personalising party bags with names or messages can add a special touch.
Creating party bags can be an enjoyable and creative process. Fill them with sweets, toys, personalised gifts, or homemade treats. The possibilities are endless, and you can tailor the contents to suit the preferences of your guests. Party bags serve as tokens of appreciation, extending the joy of the event beyond its duration.
Additionally, party bags can be themed according to the occasion. For instance, wedding party bags might include mini bottles of champagne, scented candles, or customised trinkets. For children's parties, you could include colouring books, stickers, and small toys. Themed party bags add an extra layer of excitement and can leave a lasting impression on your guests.
**Paper Bags: Eco-Friendly and Versatile**
[Paper bags](https://mrbags.co.uk/collections/paper-bags) are a versatile and environmentally friendly packaging option. From carrying groceries to serving as gift bags, they are both practical and stylish. Available in various sizes, colours, and designs, paper bags are perfect for any occasion. They can be easily decorated, making them an excellent choice for personalised gifts or party favours.
One of the main benefits of paper bags is their eco-friendliness. Unlike plastic bags, paper bags are biodegradable and recyclable, reducing their environmental impact. This makes them a preferred choice for eco-conscious individuals and businesses.
Paper bags also offer a charming and rustic aesthetic. They can be easily customised with stamps, stickers, or handwritten messages, adding a personal touch to your packaging. For businesses, branding paper bags with your logo or design can enhance your brand image and make your products stand out.
Moreover, paper bags are sturdy and capable of holding a variety of items. They are perfect for carrying groceries, books, clothing, and more. Reinforced handles and bases ensure that paper bags can support heavier items without tearing, making them a reliable packaging option.

## Why Do You Need a Salesforce Support and Maintenance Services Provider?
Implementing a CRM is not a simple task, and depending on the complexity of the project, it could take months or even years. However, going live is not the end of the story when working with Salesforce CRM. Each tool needs to be periodically updated. Additionally, the CRM system must be monitored and repaired regularly. In the Salesforce ecosystem, there are [releases](https://help.salesforce.com/s/articleView?id=sfdo.SFDO_Keep_Up_SF_Rels.htm&type=5) three times a year and you need to prepare your Salesforce Org before and after each release to ensure everything works properly.
With the growing complexity of Salesforce’s offerings and the continuous, having a reliable partner for support and maintenance ensures smooth operations and helps maximize the return on investment.
### Understanding Salesforce Support and Maintenance Services
Salesforce support and maintenance services encompass a wide range of activities designed to keep your Salesforce implementation running smoothly. These services include troubleshooting issues, implementing updates, managing user requests, and ensuring the overall health of your Salesforce environment. Here’s a closer look at what these services typically involve:
1. **Technical Support** : Addressing any technical issues or bugs that arise within your Salesforce system. This ensures that any disruptions to your operations are minimized and resolved quickly.
2. **System Maintenance** : Regular updates and maintenance tasks to keep your Salesforce system up-to-date with the latest features and security patches.
3. **User Support and Training** : Assisting end-users, including answering questions and providing training to ensure they can effectively use the system.
4. **Customization and Enhancements** : Making necessary adjustments and enhancements to the Salesforce system to align with evolving business needs and processes.
### The Importance of Expertise and Experience
When choosing a Salesforce support and maintenance services provider, their expertise and experience are paramount. A provider with a proven track record in Salesforce can offer invaluable insights and effective solutions. Here are some key points to consider:
- **Certified Professionals** : Ensure that the provider has a team of certified Salesforce professionals who are well-versed in the platform’s intricacies.
- **Industry Experience** : Look for a provider with experience in your specific industry, as they will better understand your unique needs and challenges.
- **Case Studies and References** : Review case studies and ask for references to gauge the provider’s ability to deliver successful outcomes for their clients.
### Nearshore and Offshore Salesforce Support Services
Nowadays, businesses have the option to choose between nearshore and offshore Salesforce support services. The main difference between these options is basically in the proximity of vendor’s location to your business. But this also involves additional differences in these 2 models. Understanding the differences and benefits of each can help you make the best decision for your organization.
**Nearshore Salesforce Support Services** :
- **Proximity** : Providers are located in nearby countries, often sharing similar time zones, which can facilitate better communication and collaboration.
- **Cultural Compatibility** : Nearshore providers may have a closer cultural alignment, making it easier to integrate with your in-house team.
- **Cost-Effective** : While generally more affordable than onshore services, nearshore services can still offer significant cost savings without compromising quality.
**Offshore Salesforce Support Services** :
- **Cost Savings** : Offshore services can be the most cost-effective option due to lower labor costs in other parts of the world.
- **24/7 Support** : With teams located in different time zones, offshore providers can offer round-the-clock support.
- **Access to a Larger Talent Pool** : Offshore providers can tap into a vast pool of skilled professionals, ensuring you have access to the expertise you need.
Each option has its advantages, and the choice depends on your business needs, budget, and preferred level of control and communication.
## Evaluating the Provider’s Service Offerings
When selecting a Salesforce support and maintenance services provider, it’s crucial to evaluate their range of service offerings. A comprehensive provider should offer a suite of services that cater to all aspects of Salesforce support and maintenance. Here are some key services to look for:
- **Proactive Monitoring and Maintenance** : The provider should offer continuous monitoring of your Salesforce environment to identify and resolve issues before they impact your operations. This includes regular system health checks, performance tuning, and security audits.
- **Customization and Configuration Services** : As your business evolves, so will your Salesforce requirements. A good provider should be able to customize and configure Salesforce to meet your changing needs. This includes developing custom applications, integrating third-party tools, and modifying existing workflows.
- **Data Management and Security** : Data is the lifeblood of any CRM system. Ensure that the provider has robust data management practices, including data backup, recovery, and security measures to protect sensitive information.
- **User Training and Support** : Effective use of Salesforce requires that your team is well-trained and supported. Look for a provider that offers comprehensive training programs, user documentation, and a responsive helpdesk to assist with user queries and issues.
- **Release Management** : Salesforce frequently updates its platform with new features and improvements. A reliable provider should manage these updates efficiently, ensuring that your system stays current without disrupting your operations.
### Insight:
Effective communication and collaboration are vital when working with a Salesforce support and maintenance services provider. Ensure that the provider has a well-defined communication strategy, with clear points of contact and regular updates on the status of your system. Collaboration tools, such as project management software and shared documentation, can enhance transparency and streamline workflows. By encouraging a collaborative environment, you can ensure that your provider understands your needs and can respond swiftly to any issues that arise.
### Assessing the Provider’s Track Record and Client Feedback
A provider’s track record and client feedback are strong indicators of their reliability and quality of service. Here’s how you can assess these factors:
- **Client Testimonials and Reviews** : Look for testimonials and reviews from the provider’s previous clients. These can provide insights into the provider’s strengths and areas for improvement.
- **Case Studies** : Detailed case studies showcasing the provider’s work with other clients can demonstrate their ability to handle projects similar to yours. Pay attention to the challenges faced and the solutions implemented.
- **Industry Recognition** : Awards and recognitions from industry bodies can be a testament to the provider’s expertise and reputation in the field of Salesforce support and maintenance services.
- **Client Retention Rate** : A high client retention rate often indicates satisfied clients who trust the provider with their ongoing Salesforce support needs.
### Choosing Between a Salesforce Support and Maintenance Company or a Freelancer
When deciding whether to hire a Salesforce support and maintenance company or a freelancer, consider the following factors:
**Company** :
- **Diverse Skill Set** : Companies typically have a team of professionals with a diverse set of skills, providing comprehensive support for various Salesforce needs.
- **Reliability** : Established companies often have robust processes and resources to ensure consistent and reliable service.
- **Scalability** : Companies can scale their services to meet your growing needs, offering flexibility in their support and maintenance plans.

## Factors to Consider When Choosing a Salesforce Support and Maintenance Services Provider
Selecting the right Salesforce support and maintenance services provider involves careful consideration of several factors. These factors will help you identify a provider that can meet your specific needs and ensure a smooth Salesforce experience.
### Expertise and Certifications
One of the primary factors to consider is the provider’s expertise and certifications. Salesforce offers various certification programs for different roles, such as administrators, developers, consultants, and architects. A provider with a team of certified professionals demonstrates a high level of competence and knowledge in Salesforce.
- **Certified Administrators** : They ensure your Salesforce environment is well-maintained and configured according to best practices.
- **Certified Developers** : They can customize and extend Salesforce functionalities to meet your unique business requirements. If your business uses Salesforce Commerce Cloud, consider partnering with a dedicated [Salesforce Commerce Cloud Implementation Partner](https://www.sfapps.info/how-to-choose-salesforce-implementation-services/), who has developers with experience in SFCC and can provide specialized support and expertise. These partners can help you optimize your e-commerce platform, enhance user experiences, and drive sales growth.
- **Certified Consultants** : They provide strategic guidance on how to leverage Salesforce to achieve your business goals. For businesses that rely heavily on data, engaging a [Salesforce Data Cloud Consulting](https://www.sfapps.info/why-hire-salesforce-data-cloud-consultant/) expert can ensure you make the most of your data assets. These consultants can help with data integration, analytics, and creating actionable insights from your data, thereby driving better business decisions.
- **Certified Architects** : They design and oversee complex Salesforce implementations, ensuring scalability and performance.
### Service Level Agreements (SLAs)
Service Level Agreements (SLAs) define the level of service you can expect from your provider. A well-defined SLA ensures that both parties have clear expectations regarding response times, resolution times, and the scope of services provided.
- **Response Time** : The maximum time the provider will take to acknowledge a support request.
- **Resolution Time** : The maximum time the provider will take to resolve an issue.
- **Scope of Services** : Detailed descriptions of the services included, such as support hours, types of support (remote, on-site), and the specific Salesforce functionalities covered.
### Cost and Pricing Models
Understanding the cost and pricing models of potential providers is essential to ensure their services fit within your budget. Providers may offer different pricing models, such as:
- **Fixed Price** : A set price for a predefined scope of services. This model is predictable and easier to budget for.
- **Pay-As-You-Go** : Charges are based on the actual usage of support services. This model offers flexibility but can be unpredictable in terms of cost.
- **Subscription-Based** : A recurring fee for ongoing support and maintenance services. This model provides a balance between predictability and flexibility.
### Communication and Support Channels
Effective communication is crucial for successful collaboration with your Salesforce support and maintenance services provider. Ensure the provider offers multiple support channels, such as:
- **Email Support** : For non-urgent issues and detailed inquiries.
- **Phone Support** : For immediate assistance and urgent issues.
- **Live Chat** : For quick questions and real-time support.
- **Support Portal** : A centralized platform for tracking support tickets and accessing knowledge base articles.
### Customization and Flexibility
Every business has unique needs, and your Salesforce support and maintenance services provider should be able to accommodate them. Evaluate the provider’s ability to customize their services to match your specific requirements. This includes:
- **Custom Development** : Building custom applications and integrations to enhance your Salesforce capabilities.
- **Tailored Training Programs** : Providing training sessions that are specific to your team’s needs and your Salesforce implementation.

1,900,021 | Technical Documentation: The Story of a Failure | Technical documentation is a debate that has unleashed passions in different teams, whatever their... | 0 | 2024-06-25T11:26:27 | https://dev.to/umairk/technical-documentation-the-story-of-a-failure-3f10 | Technical documentation is a debate that has unleashed passions in different teams, whatever their specialties for decades. When it needs to be written, it is deprioritized and when it is missing from a project, it delays all teams. I will therefore look at the problems of the technical documentation that I was able to observe while working as a technical writer and developer.
## A Thousand and One Reasons Not to Do Documentation
I'm not going to lie, doing documentation is not the most fun part of our jobs, but it is an integral part of it. I even think that to be a good “tech”, you don’t just have to know how to “puke code”, you have to know how to document and understand product needs, among other things. However, in many cases it is omitted, or avoided for multiple reasons. I don't think there's any good reason to avoid documentation, so I'll go through some excuses I hear quite often and see why it doesn't make sense.
### If the Code Is Clear, There Is No Need for Documentation.
Surely one of the most common excuse, in reality it reflects a deeper problem. The goal of technical documentation is not to explain the lines of code but the context of the implementation and to give an overall view to save time and efficiency.
You know how to develop, the person who will take over the code knows it too. However, what they don't know is the context in which this was done and why. Because we all know, sometimes we make strange choices that are necessary because of the context. For example, why redevelop a function to do an action, why implement a program this way. There may be reasons, technical or political, but these reasons will not be seen in the code at first glance. However, you should also not be overzealous and over-comment, having more comment lines than code is often symbolic of a problem. Let's take a telling example that I still see often, comment lines like this:
```
# Allows you to retrieve the ID
function get_id():
return this.id
```
The comment does nothing except increase the number of lines.
### We will reduce the number of man-days on documentation.
Another phrase that you must have heard often! Because yes, many IT projects end up being delayed, as in many other areas. To reduce delays, project managers have a fairly classic technique: eliminate or reduce the time given to non-priority tasks. Retain by “non-priority” all tasks that do not directly bring a return. Suffice to say that this often contains: optimization, refactoring, and documentation. So yes, it saves a few man days immediately, but in the long term this approach is not profitable. The application will have a life cycle which will need to be modified and updated many times. Every time someone has to work on it, they are going to have to take time to understand the code and the context before they can work. It is rare that over the entire life cycle of the product this is profitable.
Added to this is yet another point: you must not reinvent the wheel, so reuse the code as often as possible. If you want your code to be reused, one of the first criteria will be the presence of documentation and its organization. Example: if you do Infra As Code with Terraform, it will take you more time to separate the elements into independent modules, but you or others will be able to reuse them for various projects.
### We Have Everything Automated, There Will Be No Need for Documentation
Today with agility and the DevOps approach it is more and more common to have very mature projects on automation such as the use of continuous deployment, automated cloud infrastructure, and so on. With all this, we are sometimes tempted to say that there is no need to do documentation.
Small anecdote, I already heard an administrator who was asked by the security team to update OpenSSL urgently. He did not understand where OpenSSL was located or how to update it because in reality, he only got back a Docker image on DockerHub. I think this shows why it's important to be aware of the invisible part of the iceberg.
Knowing what automation does is part of the documentation. Six months after going live, there is little chance of remembering the specifics of the system. The documentation will get you back on track easily, especially on infrastructures which are increasingly complex.
### If I Document My Work, I Could Be Fired
This may come as a shock to some, but I have heard this phrase several times before. Moreover, it is often the same people who want to limit automation for this reason. In short, I am not throwing stones at them, I can understand that people are afraid of losing their jobs. However, we should not be fooled. From experience, the fact that there is no documentation will never prevent a company from carrying out layoffs. I even think that it will often further deteriorate the quality and the working atmosphere.
In short, don't do that, I don't think it will one day work in your favor, quite the contrary.
## Documentation in the Age of Agility and DevOps
We have seen different reasons that are often given for not doing documentation but we have not addressed a particularity that is close to my heart: documentation in the age of agility and DevOps. When we accelerated the deployment of applications and infrastructures, we saved a lot of time, but what about documentation? However, reconciling the two is important and I don’t think it’s that complicated.
To manage this in the age of DevOps, I would tend to advise the following things:
- The documentation must be part of the lifecycle, therefore be versioned and tagged like this. In general, I choose to store it in the git repository of the associated code, this avoids losing it in the process.
- Modifications must be accompanied by associated documentation, if it is done continuously it is faster. Each merge request must be accompanied by associated documentation modifications and additions.
- Writing documentation should be a reflex and should be done at the same time as the code as if it were an integral part of it. I do not recommend putting just one documentation task at the end of the project; distribute it among the technical tasks; it is an integral part of it.
- Automate as much as possible, when you document Terraform modules or REST APIs there are tools to automate a lot of it like versions, input/output, etc.
- Bring it to life, often people tend to stop reading and directly ask about cats . We have all received messages on Slack or elsewhere asking questions to which the answers were in the documentation. Kindly refer these people to the documentation and ask them to contact you again if it is not precise enough, if this is the case, improve it! Because tomorrow you may be on vacation and you won't be able to answer.
- Everyone must document what they do, it is not up to one person to take responsibility for such a central and important point.
- These are the few points that seem important to me to have an effective documentation methodology in a DevOps environment. The list nevertheless remains personal and not exhaustive.
## Finally: RTFM
Documentation is important, it saves time for you and future technicians. Yes, with reverse engineering, you can get away with it, I happened to come across obscure programs that I had to understand `strace`, `ncor` else `tcpdump`, but it is time-consuming and not effective in the long term. Also, don't be afraid to respond [“Read The Fucking Manual”](https://en.wikipedia.org/wiki/RTFM) to someone, in order to give them the reflex to read the documentation so that they gain autonomy.
As a freelance techincal writer, usually my goal is not to stay ad vitam aeternam with the client, but to help them take control so that before I leave, I only have to give them the manual and the keys to his new system.
If you don't do it for yourself, do it for the person who comes after you. Maybe you can save him weeks of uninteresting and time-consuming work.

1,900,015 | Bitcoin: A Digital Gold Rush | What is Bitcoin? Let's simplify it by comparing it to gold. Why does gold have value? Not just... | 0 | 2024-06-25T11:20:33 | https://dev.to/tushar_pal/bitcoin-a-digital-gold-rush-1mm4 | bitcoin, blog, beginners, 2min | What is Bitcoin?
Let's simplify it by comparing it to gold. Why does gold have value?
Not just because Indian aunties wear it on wedding, but because we, as a society, have collectively assigned it value. Why? Well, there's a limited supply of gold in the world, and it takes time, effort, and resources to mine it. Enter Bitcoin, our digital counterpart to gold.
Imagine Bitcoin as a digital record book, akin to a giant diary, where every transaction is meticulously recorded. This record book is called the blockchain.
Each page in this book represents a block, and every time someone engages in a Bitcoin transaction, a new block is added to the chain.
But here's the magical part: once a block is written, it's immutable—it can't be altered or erased.
**How actually it works ?**
Bitcoin utilizes something called Proof of Work, a robust algorithm that ensures the security and integrity of the network. Here's how it works: across the globe, there are individuals and organizations engaged in Bitcoin mining. These miners maintain a distributed record, essentially a long copy detailing who owns how many bitcoins.
The beauty of Bitcoin lies in its decentralized nature. It's exceedingly challenging for any single entity to control the network. Even if someone attempted to generate more bitcoins than exist in the world, the network would collectively reject such an attempt—unless they were able to compromise more than 50% of the network, a feat highly improbable due to the distributed nature of Bitcoin.
But why do people participate in Bitcoin mining? Well, they're incentivized to do so. Miners are periodically rewarded with bitcoins for their efforts in securing the network. This process not only maintains the integrity of Bitcoin but also ensures its continued operation and security.
In essence, Bitcoin operates as a digital gold rush—a decentralized, secure, and finite digital asset that derives its value from the collective trust and consensus of its users. Just as gold has been revered throughout history for its scarcity and utility, Bitcoin represents a modern-day digital store of value, underpinned by cutting-edge technology and cryptographic principles. | tushar_pal |

I'm Victor, Founder and developer at [kit.domains](https://kit.domains).
A few weeks ago, I launched KIT.domains on Product Hunt and a few other platforms. Currently, I have some stats:
- 1k visitors
- 51 customers
- 115 domains added
The project started as just **domain/SSL expiration date tracking**.
Last week, I added a few (what I think are) important features:
- Integration with Ahrefs
- Response time tracker
In my 33 years and 15 years of experience in commercial development, this is my own first ever project that I finished (I suspect I have something like ADHD).
The problem is that there are no paid customers.
Can you take a look? What could I do better?
Thanks for any advice.

people used to exchange goods like shoes for things they needed, like grains. It was a simple system, but it had its problems. As time passed, people realized it wasn't very efficient.
Then, something shiny came along - gold! Gold was special because there wasn't too much of it in the world, and you couldn't just make more whenever you wanted. So, people thought, "Hey, let's use gold to trade!" And they did, for a while.
But carrying gold around was heavy and tricky. So, the clever government folks came up with an idea. They said, "Let's make something called 'currency' that's worth a certain amount of gold." For example, they said, "One dollar equals one gram of gold."
Everything seemed fine until one day in 2008, there was big trouble in the financial world. Some big banks were playing with something called "financial instruments," and they were playing too rough. The government kind of ignored it because, well, the banks were making lots of money.
But then, uh-oh! The banks made some bad bets and lost lots of money. They owed money to people, but they didn't have it. The government thought, "We're not going to help them this time. They need to learn from their mistakes."
But then, one of the big banks went bankrupt And suddenly, the government realized that if all the banks failed, the whole economy would be in BIG trouble. And guess what? Other countries' economies were tied to ours(US ECONOMY), so it was like a big domino effect - one bank falls, and they all fall!
So, even though the government didn't want to, they had to help the banks. They gave them lots of money to keep them from falling down.
But people started asking questions. "Why does the government get to decide who to help and who not to help?" they wondered. "And why do they control the money and get to print it whenever they want?"
And then, out of this mess, came something new - Bitcoin! It's like digital gold, but nobody controls it, and nobody can just make more whenever they feel like it.
And that, my friends, is how the 2008 financial crisis led to the birth of Bitcoin, all because some people asked some big questions about who gets to decide about money. | tushar_pal | |

Our current... | 0 | 2024-06-25T11:12:05 | https://dev.to/kalstong/navigating-the-complexities-of-cloud-solutions-an-opinionated-developers-perspective-1578 | softwareengineering, architecture, cloud, aws | Working on an international project has its unique set of challenges and opportunities. Our current project involves a frontend application leveraging a Backend for Frontend (BFF) pattern running on a kubernetes (k8s) cluster and a robust backend infrastructure on AWS. We employ a variety of AWS resources, including DynamoDB, Step Functions, Lambda Functions, and CloudWatch, among others. However, among these advanced cloud solutions, I have encountered several frustrations that stem from the over-complication of software design.
**The Over-Engineering of Cloud Solutions**
One of the primary issues I have observed is the tendency of developers to become addicted with cloud solutions, leading to overly complex, heavily layered, and tightly coupled architectures. This obsession with cloud technology often results in systems that are not only slow but also significantly prevent the Developer Experience (DX).
**A Case in Point: Error Notification Workflow**
To illustrate, let's look into a specific scenario from our project. We have a Step Function that eventually triggers a Lambda function. This Lambda performs several validations and throws an exception in case of an error. Our goal was to notify a chat service whenever this Lambda encounters an error. The solution designed for this apparently simple requirement turned out to be unnecessarily convoluted:
1. **Lambda Error Handling:**
The Lambda function executes and throws an exception if it encounters an error during validation.
2. **CloudWatch Alarm:** If the Lambda throws five exceptions within a specified timeframe, a CloudWatch Alarm is triggered.
3. **SNS Notification:** The CloudWatch Alarm publishes a message to an Amazon Simple Notification Service (SNS) topic.
4. **Lambda Subscriber:** Another Lambda function subscribes to the SNS topic, receiving the alarm notification.
5. **Chat Notification:** Finally, this Lambda function sends the alert to the chat service.
**The Issues with Over-Engineering**
This elaborate workflow, while functional, exemplifies the pitfalls of over-engineering:
- **Complexity:** The multi-step process introduces unnecessary complexity, making the system harder to understand, maintain, and troubleshoot.
- **Latency:** Each step in the process adds latency, which can lead to slower response times.
- **Tight Coupling:** The design is tightly coupled to AWS services, making it challenging to migrate or adapt to other environments.
- **Poor Developer Experience (DX):** The intricate setup detracts from the overall developer experience, leading to frustration and reduced productivity.
**Simplifying for Better Developer Experience**
In hindsight, a simpler approach could have been more effective. The entire cloud backend suits well in a k8s micro-service...but it is also a good story for another day.
**Conclusion**
While cloud solutions offer powerful tools for building scalable and resilient systems, it's crucial to balance their use with simplicity and developer experience in mind. Over-complication not only hampers performance but also detracts from the overall efficiency and satisfaction of the development process. As developers, we must strive to design systems that are not only functional but also elegant and easy to maintain.
By sharing these experiences, I hope to encourage a more mindful approach to software design, where simplicity and developer experience are given the consideration they deserve.
Feel free to share your thoughts and experiences on this topic in the comments below. Let's continue the conversation and work towards more efficient and developer-friendly solutions.

1,899,990 | GBase 8c Implementation Guide: Performance Optimization | 1. Database Configuration Optimization 1.1. Memory Management The memory... | 0 | 2024-06-25T10:53:23 | https://dev.to/congcong/gbase-8c-implementation-guide-performance-optimization-il | ## 1. Database Configuration Optimization
### 1.1. Memory Management
The memory configuration of a database directly affects its processing capacity. GBase 8c provides various memory-related configuration parameters such as shared_buffers, work_mem, and max_process_memory. Properly setting these parameters can significantly enhance query performance and transaction processing capabilities.
- shared_buffers:
This is the size of the memory area used by the database to cache data. Increasing this value can reduce disk I/O operations, but it should not exceed half of the physical memory. To check the shared_buffers parameter:
```
bbp=> show shared_buffers;
shared_buffers
----------------
1GB
(1 row)
```
- work_mem:
This is the amount of memory allocated for each concurrent operation. Increasing this value appropriately can improve the execution efficiency of complex queries. To check the work_mem parameter:
```
bbp=> show work_mem;
work_mem
----------
4MB
(1 row)
```
- max_process_memory:
Sets the maximum physical memory available to a database node. It is recommended to set it to physical memory * 0.665. To check the max_process_memory parameter:
```
bbp=> show max_process_memory;
max_process_memory
--------------------
24GB
(1 row)
```
### 1.2. CPU Resource Allocation
CPU is the core resource for handling database requests. On multi-core servers, proper allocation of CPU resources can prevent resource contention and improve concurrent processing capabilities.
Set CPU Affinity: Binding database processes to specific CPU cores can reduce context switching and improve processing efficiency.
Parameters for binding cores (where n is the number of cores to bind):
```
thread_pool_attr='512, 1, (cpubind:0-n)'
thread_pool_stream_attr='512, 0.2, 1, (cpubind:0-n)'
walwriter_cpu_bind=0
```
## 2. Storage Optimization
Selecting appropriate storage devices and optimizing the storage structure are crucial for database performance.
Use SSD: Compared to traditional hard drives, solid-state drives (SSD) have faster read and write speeds, significantly enhancing the I/O performance of the database.
## 3. Data Distribution Strategy
GBase 8c supports replicated and distributed tables, using data distribution strategies to avoid resource contention during parallel computation and enhance system performance.
**Replicated Table**
A replicated table means that a copy of the data is present on each node, and data association is completed locally at the node.
**Distributed Table**
A distributed table splits a large table horizontally based on a key value across different nodes, thus improving the system's read and write performance.
Applicable Scenarios for Replicated and Distributed Tables:
## 4. SQL Statement Optimization
**(1) Index Strategy**
Indexes are key to improving query speed. Properly designing indexes can significantly reduce the range of data scanned during queries.
- Analyze Query Patterns: Create indexes for frequently queried columns based on the WHERE clause.
- Avoid Over-Indexing: While indexes can improve query speed, too many indexes can burden write operations.
- Avoid Full Table Scans: Ensure queries use indexes to avoid unnecessary full table scans.
**(2) Query Rewrite**
Optimizing SQL statements themselves can reduce the database's computational burden.
Avoid SELECT: Query only the required columns to avoid unnecessary data loading.
Use JOIN Instead of Subqueries: Where possible, use JOIN operations instead of subqueries to reduce the database's parsing load.
**(3) Batch Operations**
Batch processing can reduce transaction overhead and increase database throughput.
- Batch Insert: Use batch inserts instead of single inserts to reduce the number of transaction commits.
- Batch Update: For scenarios requiring updates to large amounts of data, use batch updates to improve efficiency.
**(4) Query Plan Analysis**
Use EXPLAIN or EXPLAIN ANALYZE to view the execution plan of queries. Adjust queries or database structures based on the execution plan.
**(5) Concurrency Control**
Concurrency control optimization mainly involves optimizing connection pool management. This includes reusing database connections as much as possible to reduce the overhead of establishing and destroying connections and configuring an appropriate connection pool size based on the application's concurrency requirements and the database's processing capacity.
**(6) Lock Strategy**
Locks are an important mechanism for controlling concurrent access. A reasonable lock strategy can reduce lock contention and improve concurrent performance.
Optimize Transaction Size: Keep transactions short to reduce lock holding time.
Use Appropriate Isolation Levels: Choose suitable transaction isolation levels based on business needs to balance performance and data consistency.
## 5. System Monitoring and Tuning
**(1) Performance Monitoring**
Real-time monitoring of database performance indicators can help promptly identify and resolve performance issues.
Use Monitoring Tools: Utilize the monitoring tools provided by GBase 8c to monitor key indicators such as CPU usage, memory usage, and I/O operations.
**(2) Log Analysis**
Slow query logs and error logs are valuable resources for optimizing database performance.
Analyze Slow Queries: Regularly analyze slow query logs to identify and optimize performance bottlenecks.
Monitor Error Logs: Timely identification and resolution of errors in database operation.
## Conclusion
Database performance tuning is a systematic project that requires comprehensive consideration from hardware configuration, system settings, SQL optimization, and concurrency control. GBase 8c provides a wealth of tuning options. Through detailed tuning, the database's processing capacity and stability can be significantly enhanced. However, tuning is not a one-time effort; it requires continuous adjustment and optimization according to business development and system changes. This guide provides a comprehensive GBase 8c database performance tuning guide, analyzing strategies and methods for performance tuning from multiple angles. In practice, detailed tuning and testing must be performed based on specific business scenarios and system environments to achieve optimal performance. | congcong | |

1,900,003 | Newyork city fast and smooth internet | New York City internet comparison Nearly all NYC internet providers start in the $40–$50 price range,... | 0 | 2024-06-25T11:03:25 | https://dev.to/bass_mvp_4ad4d2ca0143b313/newyork-city-fast-and-smooth-internet-12mb | homeinternet, newyork, city, wifi | New York City internet comparison
Nearly all NYC internet providers start in the $40–$50 price range, except Astound, which starts at about half as much as other introductory plans. The average internet speed for a basic plan is 300 Mbps, besides T-Mobile 5G. Fiber optic internet from Verizon Fios and cable internet from Spectrum are the two primary wired internet providers in New York, NY.
Best internet providers in New York City
*DIRECTV : Cheapest plans
1. - *AT&T : Best Solution
2. - *Verizon: Best fiber availability
3. - *T-Mobile: Best for simple pricing
4. - *Spectrum: Best for low equipment fees
5. - *Earthlink: Best 5G speeds**
How to choose a provider in New York City
The first and most important step in choosing a new internet provider is to search by your specific address. Not all the best internet providers are available at every household, even if they are available in your general area.
After identifying the providers available at your location, it’s time to consider other factors like price and speed.
Price: Price is one of the most important factors to consider when choosing an ISP. Evaluate the price of each plan compared to how much speed you’ll be getting. Also factor in extra costs like equipment fees, installation fees and rate increases. Astound offers some of the cheapest plans in NYC starting at $25/mo., but T-Mobile has no hidden fees, contracts or price hikes.
Speed: When choosing the right internet speed for your needs, consider how many devices are in use and what types of internet activities you do every day. If you work from home, participate in heavy-bandwidth activities like gaming or have many simultaneously connected devices, consider a faster internet speed. Verizon Fios is widely available in NYC and offers fiber speeds up to 2,000 Mbps. Optimum is also a great high-speed option if you need multi-gigabit fiber speeds.

AT&T overview
AT&T is a fiber internet service provider (ISP) available in 22 states with speeds up to 5 GB. AT&T also offers fixed wireless, 5G and DSL internet connections in some areas. AT&T has been in the internet business since it started offering dial-up in the mid-90s and has expanded its technology and coverage area over the last 30 years.
AT&T home internet is known for its simple pricing and plans with no contracts, data limits or early termination fees (ETFs). Enter your address on this page to locate AT&T Wi-Fi plans near you.
AT&T internet plans and prices
The best AT&T internet plans are listed in the following table. AT&T internet prices range from $55–$255, and its fiber plans have symmetrical upload and download speeds. Fiber uses a dedicated line that provides bandwidth to your home without sharing the connection with your neighbors, like a cable or 5G connection. This technology results in less lag, faster upload speeds and more secure data transfer.
AT&T Internet 300, 500 or 1 Gig
AT&T plans with speeds of 1 GB or less will keep your monthly internet bill under $100/mo., and your price will stay the same even after the first year. This price stability differs from other providers offering cheap promo prices that increase by 50% or more after 12 months. Speeds of 300, 500 or 1 Gig can support all online activities, from live gaming to streaming movies, TV or social media content. If you’re unsure which speed you need, you have the flexibility to start with the cheaper option and upgrade later if necessary. You won’t lose out on promotional pricing by changing your plan with AT&T.

---------------------------------------------------------------------------
Verizon – Best fiber availability
Verizon Fios offers four fiber internet plans ranging from 300 Mbps to 2,000 Mbps. Prices start at $49.99/mo., and you can get a discount if you bundle your plan with mobile. The Verizon fiber network is available in 93% of New York City, even more widespread than cable internet from Spectrum. The provider’s equipment rental fees are included in the cost of service, but check for an installation fee. Verizon has no contracts or data caps, making this plan a great option if you need unlimited internet with flexible terms.

T-Mobile – Best for simple pricing
T-Mobile’s 5G Home Internet service is available to 73% of NYC. T-Mobile offers one 5G plan for $60/mo. with speeds ranging from 72–245 Mbps. T-Mobile’s biggest selling point is its simple pricing without data caps or frequent price increases. T-Mobile mails you the equipment with two-day shipping, and self-installation only involves plugging the device into an outlet. T-Mobile 5G is a good match for individuals who want a straightforward plan that’s easy to set up and maintain. However, T-Mobile speed limitations aren’t great for households with 20+ connected devices.

1,900,002 | Understanding Django's settings.py File: A Comprehensive Guide for Beginners | Introduction The settings.py file is often referred to as the heart of a Django project.... | 0 | 2024-06-25T11:03:10 | https://dev.to/rupesh_mishra/understanding-djangos-settingspy-file-a-comprehensive-guide-for-beginners-4n5b | beginners, programming, python, backenddevelopment |
## Introduction
The `settings.py` file is often referred to as the heart of a Django project. It contains all the configuration of your Django installation, controlling aspects like database settings, installed applications, middleware, URL configuration, static file directories, and much more. Understanding this file is crucial for any Django developer, as it allows you to customize your project to meet specific requirements.
In this guide, we'll walk through each section of a typical `settings.py` file, explaining what each setting does and how you might want to configure it for your project.
## Table of Contents
1. [Import os and Path](#1-import-os-and-path)
2. [Base Directory](#2-base-directory)
3. [Secret Key](#3-secret-key)
4. [Debug Mode](#4-debug-mode)
5. [Allowed Hosts](#5-allowed-hosts)
6. [Installed Apps](#6-installed-apps)
7. [Middleware](#7-middleware)
8. [URL Configuration](#8-url-configuration)
9. [Templates](#9-templates)
10. [WSGI Application](#10-wsgi-application)
11. [Database Configuration](#11-database-configuration)
12. [Password Validation](#12-password-validation)
13. [Internationalization](#13-internationalization)
14. [Static Files](#14-static-files)
15. [Default Auto Field](#15-default-auto-field)
Let's dive into each section:
## 1. Import os and Path
```python
import os
from pathlib import Path
```
These lines import the `os` module and the `Path` class from the `pathlib` module. These are used to handle file paths in a way that's compatible with different operating systems.
## 2. Base Directory
```python
BASE_DIR = Path(__file__).resolve().parent.parent
```
This line sets the `BASE_DIR` variable to the parent directory of the directory containing the `settings.py` file. This is typically the root directory of your Django project. It's used as a reference point for other file paths in the settings.
## 3. Secret Key
```python
SECRET_KEY = 'your-secret-key-here'
```
The secret key is used for cryptographic signing in Django. It should be kept secret and should be unique for each Django installation. In production, you should never hardcode this in your settings file. Instead, you can use environment variables:
```python
SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY')
```
## 4. Debug Mode
```python
DEBUG = True
```
Debug mode provides detailed error pages and should be set to `False` in production. You can use an environment variable to control this:
```python
DEBUG = os.environ.get('DJANGO_DEBUG', '') != 'False'
```
## 5. Allowed Hosts
```python
ALLOWED_HOSTS = []
```
This is a list of host/domain names that your Django site can serve. This is a security measure to prevent HTTP Host header attacks. For development, you can use:
```python
ALLOWED_HOSTS = ['localhost', '127.0.0.1']
```
For production, you'd list your domain name:
```python
ALLOWED_HOSTS = ['www.yourdomain.com']
```
## 6. Installed Apps
```python
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
```
This list tells Django which applications are active for this project. The default list includes Django's built-in applications. You'll add your own applications to this list as you create them:
```python
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'myapp', # your custom app
'another_app', # another custom app
]
```
## 7. Middleware
```python
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
```
Middleware is a framework of hooks into Django's request/response processing. It's a light, low-level "plugin" system for globally altering Django's input or output. You might add custom middleware here:
```python
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'myproject.middleware.CustomMiddleware', # your custom middleware
]
```
## 8. URL Configuration
```python
ROOT_URLCONF = 'myproject.urls'
```
This specifies the Python module where your URL patterns are defined. By default, it points to the `urls.py` file in your project directory.
## 9. Templates
```python
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
```
This setting configures template rendering. The `DIRS` list is where you can specify directories where Django should look for template files. For example:
```python
'DIRS': [BASE_DIR / 'templates'],
```
## 10. WSGI Application
```python
WSGI_APPLICATION = 'myproject.wsgi.application'
```
This specifies the WSGI application to use in your project. WSGI is the Python standard for web servers and applications.
## 11. Database Configuration
```python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': BASE_DIR / 'db.sqlite3',
}
}
```
This configures the database. By default, it uses SQLite. For a production PostgreSQL database, you might use:
```python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'your_db_name',
'USER': 'your_db_user',
'PASSWORD': 'your_db_password',
'HOST': 'localhost',
'PORT': '5432',
}
}
```
## 12. Password Validation
```python
AUTH_PASSWORD_VALIDATORS = [
{
'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',
},
{
'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',
},
]
```
This setting configures the password validation rules. You can add custom validators or remove some if needed.
## 13. Internationalization
```python
LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_TZ = True
```
These settings control language and time zone behavior. Adjust `LANGUAGE_CODE` and `TIME_ZONE` as needed for your project.
## 14. Static Files
```python
STATIC_URL = 'static/'
```
This is the URL to use when referring to static files. You might also want to add:
```python
STATICFILES_DIRS = [BASE_DIR / 'static']
STATIC_ROOT = BASE_DIR / 'staticfiles'
```
`STATICFILES_DIRS` tells Django where to look for static files in your project. `STATIC_ROOT` is the directory where Django will collect all static files for deployment.
## 15. Default Auto Field
```python
DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'
```
This sets the default primary key field type for models. `BigAutoField` is recommended for new projects.
## Conclusion
Understanding the `settings.py` file is crucial for configuring your Django project correctly. As your project grows, you'll likely need to modify these settings and add new ones. Always refer to the Django documentation for the most up-to-date information on these settings and best practices for configuring them.
Remember, some settings (like `SECRET_KEY` and database credentials) should never be hardcoded in your `settings.py` file for production environments. Use environment variables or a separate settings file for sensitive information.

1,900,001 | GBase 8s SYSBldRelease() Function Guide | 1. Overview of SYSBldRelease() Function From a session connected to a GBase 8s database... | 0 | 2024-06-25T11:03:02 | https://dev.to/congcong/gbase-8s-sysbldrelease-function-guide-2k15 | ## 1. Overview of SYSBldRelease() Function
From a session connected to a GBase 8s database that supports explicit transaction logging, you can register or unregister DataBlade modules by calling the built-in `SYSBldPrepare()` SQL function. Another built-in function, `SYSBldRelease()`, returns the version string of the `SYSBldPrepare()` function in the local database.
An alternative method for registering and unregistering DataBlade modules using SQL functions is the BladeManager utility. The BladeManager utility can perform various DataBlade module tasks, including registration, unregistration, and displaying information about DataBlade modules. This utility supports both command-line and graphical user interfaces.
`SYSBldRelease()` is defined with a function signature in all databases of a GBase 8s server instance. You can call this function using the SQL `EXECUTE FUNCTION` statement or the SPL `CALL` statement to return the version string of the `SYSBldPrepare()` function.
## 2. Detailed Explanation and Application of SYSBldRelease() Function
The following details the definition of the `SYSBldRelease()` function:
```
CREATE FUNCTION gbasedbt.sysbldrelease()
RETURNS LVARCHAR
EXTERNAL NAME
'$GBASEDBTDIR/extend/%SYSBLDDIR%/ifxmngr.bld(MackRelease)'
LANGUAGE C NOT VARIANT;
GRANT EXECUTE ON FUNCTION SYSBldRelease() TO PUBLIC;
```
This function does not take any parameters. It returns the version string and the completion date of the SYSBldPrepare() function.
The returned version string has the following format:
```
major.minor.os_codeCinterim
```
Here, C is a literal character, and major, minor, os_code, and interim version string elements have the same semantics as in the Module Reference segment of the `SYSBldPrepare()` function, without the asterisk (*) wildcard notation.
The `SYSBldRelease()` function is particularly useful when contacting GBase support with issues related to `SYSBldPrepare()`.
For `SYSBldRelease()` to return the correct version string of `SYSBldPrepare()`, the `SYSBldPrepare()` function must be called at least once in the same database. The call to `SYSBldPrepare()` does not need to occur in the same session as the call to `SYSBldRelease()`. | congcong | |

### 1 Guide Assumptions
This guide is designed for beginners who want to get started with creating a Phoenix application from scratch.
It does not assume that you have any prior experience with Phoenix.
Phoenix is a web application framework running on the Elixir programming language. If you have no prior experience with Elixir, you will find a very steep learning curve diving straight into Phoenix. There are several curated lists of online resources for learning Phoenix:
- [Elixir Introduction](https://hexdocs.pm/elixir/introduction.html)
- [Community Resources](https://elixir-lang.org/learning.html)
### 2 What is Phoenix?
> Phoenix is a web development framework written in Elixir which implements the server-side Model View Controller (MVC) pattern. Many of its components and concepts will seem familiar to those of us with experience in other web frameworks like Ruby on Rails or Python's Django.
>
> Phoenix provides the best of both worlds - high developer productivity and high application performance. It also has some interesting new twists like channels for implementing realtime features and pre-compiled templates for blazing speed.
[source](https://hexdocs.pm/phoenix/overview.html)
### 3 Creating a new Phoenix Project
The best way to read this guide is to follow it step by step. All steps are essential to run this example application and no additional code or steps are needed.
By following along with this guide, you'll create a Phoenix project called `blog`, a (very) simple weblog. Before you can start building the application, you need to make sure that you have Phoenix itself installed.
#### 3.1 Installing Phoenix
[Official Phoenix Install Guide](https://hexdocs.pm/phoenix/installation.html)
Prerequisites:
- elixir
- SQLite3
##### 3.1.1 Installing Elixir
Verify that you have a current version of Elixir installed:
```shell
$ elixir -v
Erlang/OTP 27 [erts-15.0] [source] [64-bit] [smp:20:20] [ds:20:20:10] [async-threads:1] [jit:ns]
Elixir 1.17.1 (compiled with Erlang/OTP 27)
```
Phoenix requires a Elixir version 1.14.1/Erlang 24 or later.
For installation methods, check out [the official docs](https://elixir-lang.org/install.html).
##### 3.1.2 Installing SQLite3
You will also need an installation of SQLite3.
Verify that is correctly installed and in your load `PATH`:
```shell
$ sqlite3 --version
```
##### 3.1.3 Installing Phoenix
To install Phoenix, use the `mix` command:
```shell
$ mix archive.install hex phx_new
```
To verify Phoenix was installed correctly, run the command:
```shell
mix phx.new
```
#### 3.2 Creating the Blog Application
Phoenix comes with a number of scripts called generators that are designed to make development easier and quicker by creating files with boilerplate code. One of these is the new application generator, which will provide you with a foundation of a fresh Phoenix application so that you don't have to write it yourself.
To use this generator, open a terminal, navigate to a directory, and run:
```shell
$ mix phx.new blog --database sqlite3
```
This will create a Phoenix application called Blog in a `blog` directory and install all dependencies that are already in the `mix.exs` file using `mix deps.get`.
> :warning: You can see all the command line options the Phoenix application generator accepts by running `mix phx.new`
After you create the blog application, switch to its directory:
```shell
$ cd blog
```
The `blog` directory will have a number of generated files and folder that make up a structure of a Phoenix application. Most of the work of this tutorial will happen in the `lib` folder, but here's a basic rundown of each of the files and folders that Phoenix creates by default:
| File/Folder | Purpose |
| --- |------------------------------------------------------------------------------------------------------------------------------------------|
| assets/ | Contains your css and javascript assets for your application. |
| config/ | General and environment specific configuration for your application. |
| lib/ | Contains your contexts, schemas, controllers, views of your application. You'll focus on this directory for the remainder of this guide. |
| priv/ | Contains your I18n translations, database migrations, and static assets. |
| test/ | Unit tests, fixtures, and other test files |
| .formatter.exs | Config file for Elixir code formatting. See more [here](https://hexdocs.pm/mix/main/Mix.Tasks.Format.html). |
| .gitignore | Default `.gitignore` file for Phoenix applications to not commit generated files to git repositories. |
| mix.exs | Used to specify the main configuration for the project, application, and dependencies. |
| README.md | Standard README that details how to run a Phoenix application. |
### 4 Hello Phoenix
To begin with, let's get some text on the screen quickly. To do this, you'll need your Phoenix application server running.
#### 4.1 Starting Up the Web Server
You actually have a functional Phoenix application already.
To see it, you need to start a web server on your development machine. But first we need to create and migrate the database. You can do this by running the following commands in the `blog` directory:
```shell
$ mix ecto.create
$ mix ecto.migrate
```
Then start the server with:
```shell
$ mix phx.server
```
To see your application in action, open the browser window and navigate to [http://localhost:4000](http://localhost:4000). You should see the default Phoenix information page.
To stop the server, hit Ctrl-C in the terminal window. In the development environment, Phoenix does not generally require you to restart the server; changes you make in files will be automatically picked up by the server.
#### 4.2 Say "Hello", Phoenix
To get Phoenix saying "Hello", you need to create at minimum a route, a controller with an action, and a view. A route maps a request to a controller action. A controller action performs the necessary work to handle the request, and prepares any data for the view. A view displays data in a desired format.
Let's start by adding a route to our routes file, `lib/blog_web/router.ex` at the bottom of the `scope "/", BlogWeb do` block:
```elixir
scope "/", BlogWeb do
pipe_through :browser
get "/", PageController, :home
get "/articles", ArticleController, :index
end
```
The route above declares that `GET /articles` requests are mapped to the index action of `ArticleController`.
Let's create the `ArticleController` at `lib/blog_web/controllers/article_controller.ex` with our `index` action next:
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
def index(conn, _params) do
render(conn, :index)
end
end
```
Next let's create an HTML view, which gets collocated with the controller in `lib/blog_web/controllers/article_html.ex`:
```elixir
defmodule BlogWeb.ArticleHTML do
use BlogWeb, :html
embed_templates "article_html/*"
end
```
Then finally create the HTML template in `lib/blog_web/controllers/article_html/index.html.heex`:
```html
<h1 class="text-lg text-brand">
Hello Phoenix
</h1>
```
Visit [http://localhost:4000/articles](http://localhost:4000) to see Phoenix display "Hello Phoenix"!
#### 4.3 Setting the Application to Home Page
At the moment, http://localhost:4000 still displays the default Phoenix page. Let's display our "Hello, Phoenix!" text at http://localhost:4000 as well. To do so, we will add a route that maps the root path of our application to the appropriate controller and action.
Let's open `lib/blog_web/router.ex` and add the `get "/"` path to map to the `ArticleController` `index` action:
```elixir
scope "/", BlogWeb do
pipe_through :browser
get "/", ArticleController, :index
get "/articles", ArticleController, :index
end
```
### 5 Autoloading
TODO?
### 6 MVC and You
So far, we've discussed routes, controllers, actions, and views. All of these are typical pieces of a web application that follows the [MVC (Model-View-Controller)](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) pattern. MVC is a design pattern that divides the responsibilities of an application to make it easier to reason about. Phoenix follows this design pattern by convention.
Since we have a controller and a view to work with, let's generate the next piece: a model.
#### 6.1 Generating a model
The _model_ in Phoenix is actually an [Ecto Schema](https://hexdocs.pm/ecto/Ecto.Schema.html). Schemas behave similarly to models from other frameworks, such as mapping external data into Elixir structs. But the difference to other frameworks is that schemas area much more solely focused on that mapping of external data.
To generate a schema, we'll use the [schema generator](https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.Schema.html) to generate an `article` schema which contains `title` and `body` database fields.
```shell
$ mix phx.gen.schema MyBlog.Article articles title:string body:text
* creating lib/blog/my_blog/article.ex
* creating priv/repo/migrations/20240311211707_create_articles.exs
Remember to update your repository by running migrations:
$ mix ecto.migrate
```
This command will create two new files:
1. Schema file at `lib/blog_my_blog/article.ex` in the `my_blog` context.
2. Migration file at `priv/repo/migrations/<timestamp>_create_articles.exs`.
#### 6.2 Database Migrations
Migrations are used to alter the structure of an application's database. In Phoenix applications, migrations are written in Elixir so that they can be database-agnostic.
Let's take a look at the contents of our new migration file:
```elixir
defmodule Blog.Repo.Migrations.CreateArticles do
use Ecto.Migration
def change do
create table(:articles) do
add :title, :string
add :body, :text
timestamps(type: :utc_datetime)
end
end
end
```
The `create table(:articles) do` block specifies how the new `articles` table should be constructed. By default, the table is automatically created with an auto-incrementing primary key `id` field.
Inside the block for `create table(:articles)`, two columns are defined: `title` and `body`. These were added by the generator because we included them in our generate command.
On the last line of the block is `timestamps(type: :utc_datetime)`. This method defines two additional columns named `inserted_at` and `updated_at`. Phoenix will manage these for us, setting the values when we create or update a schema.
Let's run our migration with the following command:
```shell
$ mix ecto.migrate
```
The command will display output indicating that the table was created:
```shell
Compiling 2 files (.ex)
Generated blog app
17:19:38.008 [info] == Running 20240311211707 Blog.Repo.Migrations.CreateArticles.change/0 forward
17:19:38.010 [info] create table articles
17:19:38.102 [info] == Migrated 20240311211707 in 0.0s
```
### 6.3 Using the Model to Interact with the Database
Let's launch the console with this command:
```shell
$ iex -S mix
```
You should see an iex prompt like:
```shell
Erlang/OTP 26 [erts-14.2.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [dtrace]
Interactive Elixir (1.16.1) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
```
At this prompt, we can initialize a new Article object:
```shell
iex(1)> alias Blog.MyBlog.Article
Blog.MyBlog.Article
iex(2)> alias Blog.Repo
Blog.Repo
iex(3)> article = Repo.insert(%Article{title: "Hello Phoenix", body: "I am on Phoenix!"})
[debug] QUERY OK source="articles" db=1.6ms idle=1638.2ms
INSERT INTO "articles" ("title","body","inserted_at","updated_at") VALUES ($1,$2,$3,$4) RETURNING "id" ["Hello Phoenix", "I am on Phoenix!", ~U[2024-03-11 21:34:35Z], ~U[2024-03-11 21:34:35Z]]
↳ :elixir.eval_external_handler/3, at: src/elixir.erl:405
{:ok,
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 1,
title: "Hello Phoenix",
body: "I am on Phoenix!",
inserted_at: ~U[2024-03-11 21:34:35Z],
updated_at: ~U[2024-03-11 21:34:35Z]
}}
```
The above output shows an INSERT INTO "articles" ... database query. This indicates that the article has been inserted into our table. And if we take a look at the article object again, we see something interesting has happened:
```shell
iex(4)> article
{:ok,
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 1,
title: "Hello Phoenix",
body: "I am on Phoenix!",
inserted_at: ~U[2024-03-11 21:34:35Z],
updated_at: ~U[2024-03-11 21:34:35Z]
}}
```
The id, created_at, and updated_at attributes of the object are now set. Phoenix did this for us when we saved the object.
When we want to fetch this article from the database, we can call find on the model and pass the id as an argument:
```shell
iex(5)> Repo.get!(Article, 1)
[debug] QUERY OK source="articles" db=1.3ms queue=1.3ms idle=533.9ms
SELECT a0."id", a0."title", a0."body", a0."inserted_at", a0."updated_at" FROM "articles" AS a0 WHERE (a0."id" = $1) [1]
↳ :elixir.eval_external_handler/3, at: src/elixir.erl:405
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 1,
title: "Hello Phoenix",
body: "I am on Phoenix!",
inserted_at: ~U[2024-03-11 21:34:35Z],
updated_at: ~U[2024-03-11 21:34:35Z]
}
```
And when we want to fetch all articles from the database, we can call all using the repo:
```shell
iex(7)> Repo.all(Article)
[debug] QUERY OK source="articles" db=2.0ms queue=2.6ms idle=1101.3ms
SELECT a0."id", a0."title", a0."body", a0."inserted_at", a0."updated_at" FROM "articles" AS a0 []
↳ :elixir.eval_external_handler/3, at: src/elixir.erl:405
[
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 1,
title: "Hello Phoenix",
body: "I am on Phoenix!",
inserted_at: ~U[2024-03-11 21:34:35Z],
updated_at: ~U[2024-03-11 21:34:35Z]
}
]
```
Exit the shell by doing `Ctrl-C` twice.
#### 6.4 Showing a List of Articles
Phoenix has a notion of organizing code into a domain-driven-design (DDD) style structure with the use of Contexts. Contexts are used as an abstraction layer between schemas and the rest of the application, by encapsulating data access and data validation.
Let's create our `MyBlog` context at `lib/blog/my_blog.ex`:
```elixir
defmodule Blog.MyBlog do
import Ecto.Query, warn: false
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
end
```
Here we're using `alias` in order to more easily reference different modules. We've created a `list_articles` function that takes no params, and will return all the articles in the database by using the `Repo`. We will use this `list_articles` function in the controller, rather than using `Repo` directly.
Let's update the `index` action of the `ArticleController` at `lib/blog_web/article_controller.ex`:
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
end
```
We are getting the `articles` in the database by using our `MyBlog` context's `list_articles` function, then assigning the articles in our HTML template the key `articles`. This will allow us to access the articles by using `@articles` in our template.
Let's update the HTML to use the passed in `@articles` in `lib/blog_web/controllers/article_html/index.html.heex`:
```html
<h1 class="text-lg text-brand">
Hello Phoenix
</h1>
<ul class="pt-5">
<%= for article <- @articles do %>
<li>
<%= article.title %>
</li>
<% end %>
</ul>
```
We are looping over all of the `@articles` with a `for` loop. For each `article` in `@articles`, we will display the article's title.
Navigate to http://localhost:4000 and see the article's we've created so far.
### 7 CRUDit Where CRUDit Is Due
Almost all web applications involve CRUD (Create, Read, Update, and Delete) operations. You may even find that the majority of the work your application does is CRUD. Phoenix acknowledges this, and provides many features to help simplify code doing CRUD.
Let's begin exploring these features by adding more functionality to our application.
#### 7.1 Showing a Single Article
We currently have an `index` view that list all of our articles in our database. Let's add a new view that shows the title and body of a single article.
We start by adding a new route that maps to our new controller action (which we will add next). Open `lib/blog/router.ex` and insert the last route shown here:
```elixir
scope "/", BlogWeb do
pipe_through :browser
get "/", ArticleController, :index
get "/articles", ArticleController, :index
get "/articles/:id", ArticleController, :show
end
```
The new route is another `get` route, but it has something extra in its path: `:id`. This designates a route _parameter_. A route parameter captures a segment of the request's path, and puts that value in the params map. For example, when handling a request like `GET http://localhost:4000/articles/1`, `1` would be captured as the value for `:id`.
Let's first update our `MyBlog` context with a function that retrieves an `Article` based on its primary key `id` in `lib/blog/my_blog/my_blog.ex`:
```elixir
defmodule Blog.MyBlog do
import Ecto.Query
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
def get_article!(id) do
Repo.get!(Article, id)
end
end
```
Then let's add the `show` method which uses the new context method to the controller at `lib/blog_web/controllers/article_controller.ex`:
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
def show(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
render(conn, :show, article: article)
end
end
```
The `show` action method pulls the `id` from the incoming params, and passes the `id` to the `MyBlog` context's `get_article!(id)` function. The `get_article!` method in the context will return the article with the matching `id`. Lastly the `show` action assigns the `article` to the template variable named `article`, which will be accessible in the template using the `@article` variable.
Then let's create a new HTML template at `lib/blog_web/controllers/article_html/show.html.heex` at access the article using `@article` to display its title and body:
```html
<h1>
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
```
Now we can see the article when we visit http://localhost:4000/articles/1!
To finish up, let's add a convenient way to get to an article's page. We'll link each article's title in `lib/blog_web/controllers/article_html/index.html.heex` to its page:
```html
<h1 class="text-lg text-brand">
Hello Phoenix
</h1>
<ul class="pt-5">
<%= for article <- @articles do %>
<li>
<a href={~p"/articles/#{article}"}>
<%= article.title %>
</a>
</li>
<% end %>
</ul>
```
### 7.2 Resource Routing
So far, we've covered the "R" (Read) of CRUD. We will eventually cover the "C" (Create), "U" (Update), and "D" (Delete). As you might have guessed, we will do so by adding new routes, controller actions, and views. Whenever we have such a combination of routes, controller actions, and views that work together to perform CRUD operations on an entity, we call that entity a resource. For example, in our application, we would say an article is a resource.
Phoenix provides a routes method named resources that maps all of the conventional routes for a collection of resources, such as articles.
So before we proceed to the "C", "U", and "D" sections, let's replace the two get routes in `lib/blog_web/router.ex` with resources:
```elixir
scope "/", BlogWeb do
pipe_through :browser
get "/", ArticleController, :index
resources "/articles", ArticleController
end
```
We can inspect what routes are mapped by running the `mix phx.routes` routes command:
```shell
...
GET / BlogWeb.ArticleController :index
GET /articles BlogWeb.ArticleController :index
GET /articles/:id/edit BlogWeb.ArticleController :edit
GET /articles/new BlogWeb.ArticleController :new
GET /articles/:id BlogWeb.ArticleController :show
POST /articles BlogWeb.ArticleController :create
PATCH /articles/:id BlogWeb.ArticleController :update
PUT /articles/:id BlogWeb.ArticleController :update
DELETE /articles/:id BlogWeb.ArticleController :delete
...
```
Nice!
### 7.3 Creating a New Article
Now we move on to the "C" (Create) of CRUD. Typically, in web applications, creating a new resource is a multi-step process. First, the user requests a form to fill out. Then, the user submits the form. If there are no errors, then the resource is created and some kind of confirmation is displayed. Else, the form is redisplayed with error messages, and the process is repeated.
In a Phoenix application, these steps are conventionally handled by a controller's new and create actions.
First let's add two new functions `change_article` and `create_article` to the context `lib/blog/my_blog.ex`:
```elixir
defmodule Blog.MyBlog do
import Ecto.Query, warn: false
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
def get_article!(id) do
Repo.get!(Article, id)
end
def change_article(%Article{} = article, attrs \\ %{}) do
Article.changeset(article, attrs)
end
def create_article(attrs \\ %{}) do
%Article{}
|> Article.changeset(attrs)
|> Repo.insert()
end
end
```
Then let's add a typical implementation of the `new` and `create` actions to `lib/blog_web/article_controller.ex` using the methods just added to the context, below the show action:
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Article
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
def show(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
render(conn, :show, article: article)
end
def new(conn, _params) do
changeset = MyBlog.change_article(%Article{})
render(conn, :new, changeset: changeset)
end
def create(conn, _params) do
case MyBlog.create_article(%{title: "...", body: "..."}) do
{:ok, article} ->
conn
|> put_flash(:info, "Article created successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
end
```
The `new` create a changeset for an article, but does not save it.
By default, the new action will render `lib/blog_web/controllers/article_web/new.html.heex`, which we will create next.
The `create` action instantiates a new article with values for the title and body, and attempts to save it. If the article is saved successfully, the action redirects the browser to the article's page at "http://localhost:4000/articles/#{article.id}". Else, the action redisplays the form by rendering `lib/blog_web/article_html/new.html.heex` with status code 422 Unprocessable Entity. The title and body here are dummy values. After we create the form, we will come back and change these.
#### 7.3.1 Using a Form Builder
We will use a feature of Phoenix called a form builder to create our form. Using a form builder, we can write a minimal amount of code to output a form that is fully configured and follows Phoenix conventions.
Let's create `lib/blog_web/article_html/new.html.heex` with the following contents:
```html
<h1>
New Article
</h1>
// replace with normal html?
<.simple_form :let={f} for={@changeset} action={~p"/articles"}>
<.error :if={@changeset.action}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={f[:title]} type="text" label="Title" />
<.input field={f[:body]} type="text" label="Body" />
<:actions>
<.button>Save Article</.button>
</:actions>
</.simple_form>
```
The `simple_form` helper...
The resulting output of our `simple_form` will look like:
```html
<form action="/articles" method="post">
<input name="_csrf_token" type="hidden" hidden="" value="...">
<div class="mt-10 space-y-8 bg-white">
<!-- @caller lib/blog_web/controllers/article_html/new.html.heex:9 () -->

Save Article
</button><!-- </BlogWeb.CoreComponents.button> -->
</div>
</div>
</form>
```
#### 7.3.2 Using Parameters
Submitted form data is put into the `article_params` map. We could pass or pluck these values individually to `MyBlog.create_article`, but that would be verbose and possibly error-prone. And it would become worse as we add more fields.
Instead, we will pass a single map that contains values from the form. In order to prevent anything malicious from happening if extra params are submitted, we will `cast` the fields we want in the article schema's `changeset` function.
Let's update the `create` action in the controller `lib/blog_web/article_controller.ex` to use the values in the `article_params` param:
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Article
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
def show(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
render(conn, :show, article: article)
end
def new(conn, _params) do
changeset = MyBlog.change_article(%Article{})
render(conn, :new, changeset: changeset)
end
def create(conn, %{"article" => article_params}) do
case MyBlog.create_article(article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article created successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
end
```
Try creating by visiting [http://localhost:4000/articles/new](http://localhost:4000/articles/new) now. After creating a new article, you should be redirected to that article's show page.
#### 7.3.3 Validations and Displaying Error Messages
Try creating a new article without a title or body. You should see `can't be blank` error messages under the title input and body input. These validations for the article `title` and `body` field were created for us in the schema that was generated when we ran `mix phx.gen.schema`. Open `lib/blog/my_blog/article.ex` and notice the usage of `validate_required` in the `changeset` function:
```elixir
defmodule Blog.MyBlog.Article do
use Ecto.Schema
import Ecto.Changeset
schema "articles" do
field :title, :string
field :body, :string
timestamps(type: :utc_datetime)
end
@doc false
def changeset(article, attrs) do
article
|> cast(attrs, [:title, :body])
|> validate_required([:title, :body])
end
end
```
Let's add an additional length check validation to the `body` field in `lib/blog/my_blog/article.ex`:
```elixir
defmodule Blog.MyBlog.Article do
use Ecto.Schema
import Ecto.Changeset
schema "articles" do
field :title, :string
field :body, :string
timestamps(type: :utc_datetime)
end
@doc false
def changeset(article, attrs) do
article
|> cast(attrs, [:title, :body])
|> validate_required([:title, :body])
|> validate_length(:body, min: 10)
end
end
```
Test the new validation by visiting http://localhost:4000/articles/new and try submitting the form with a body with less than 10 characters.
To understand how all of this works together, let's take another look at the new and create controller actions:
```elixir
def new(conn, _params) do
changeset = MyBlog.change_article(%Article{})
render(conn, :new, changeset: changeset)
end
def create(conn, %{"article" => article_params}) do
case MyBlog.create_article(article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article created successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
```
When we visit http://localhost:4000/articles/new, the GET /articles/new request is mapped to the `new` action. The `new` action does not attempt to save `article`. Therefore, validations are not checked, and there will be no error messages.
When we submit the form, the POST /articles request is mapped to the `create` action. The `create` action does attempt to save `article`. Therefore, validations are checked. If any validation fails, `article` will not be saved, and `lib/blog_web/article_html/new.html.heex` will be rendered with error messages.
#### 7.3.4 Finishing Up
We can now create an article by visiting http://localhost:4000/articles/new. To finish up, let's link to that page from the top of `lib/blog_web/article_html/index.html.heex`:
```html
<h1 class="text-lg text-brand">
Hello Phoenix
</h1>
<a href={~p"/articles/new"}>
New Article
</a>
<ul class="pt-5">
<%= for article <- @articles do %>
<li>
<a href={~p"/articles/#{article}"}>
<%= article.title %>
</a>
</li>
<% end %>
</ul>
```
### 7.4 Updating an Article
We've covered the "CR" of CRUD. Now let's move on to the "U" (Update). Updating a resource is very similar to creating a resource. They are both multi-step processes. First, the user requests a form to edit the data. Then, the user submits the form. If there are no errors, then the resource is updated. Else, the form is redisplayed with error messages, and the process is repeated.
These steps are conventionally handled by a controller's edit and update actions. Let's add a typical implementation of these actions to `lib/blog_web/article_controller.ex`, below the create action::
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Article
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
def show(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
render(conn, :show, article: article)
end
def new(conn, _params) do
changeset = MyBlog.change_article(%Article{})
render(conn, :new, changeset: changeset)
end
def create(conn, %{"article" => article_params}) do
case MyBlog.create_article(article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article created successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
def edit(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
changeset = MyBlog.change_article(article)
render(conn, :edit, article: article, changeset: changeset)
end
def update(conn, %{"id" => id, "article" => article_params}) do
article = MyBlog.get_article!(id)
case MyBlog.update_article(article, article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article updated successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :edit, article: article, changeset: changeset)
end
end
end
```
Notice how the edit and update actions resemble the new and create actions. The edit action fetches the article from the database, and passes it to the view so that it can be used when building the form. The edit action fetches the article from the database, creates a changeset using that article, and passes the article and the changeset to the view. By using the argument `:edit` in the `render` function, the edit action will render `lib/blog_web/controllers/article_html/edit.html.heex`.
The update action (re-)fetches the article from the database, and attempts to update it with the submitted form data filtered by article_params. If no validations fail and the update is successful, the action redirects the browser to the article's page. Else, the action redisplays the form — with error messages — by rendering `lib/blog_web/controllers/article_html/edit.html.heex`.
The `edit` method uses the methods `MyBlog.get_article!` and `MyBlog.change_article` we already have in the `MyBlog` context. But the `update` action uses a method we still need to add: `MyBlog.update_article`. Add `update_article` to the `MyBlog` context.
```elixir
defmodule Blog.MyBlog do
import Ecto.Query, warn: false
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
def get_article!(id) do
Repo.get!(Article, id)
end
def change_article(%Article{} = article, attrs \\ %{}) do
Article.changeset(article, attrs)
end
def create_article(attrs \\ %{}) do
%Article{}
|> Article.changeset(attrs)
|> Repo.insert()
end
def update_article(%Article{} = article, attrs) do
article
|> Article.changeset(attrs)
|> Repo.update()
end
end
```
#### 7.4.1 Using Partials to Share View Code
Our `edit` form will look the same as our `new` form.
Because the code will be the same, we're going to factor it out into a shared view called a partial. Let's create `lib/blog_web/controllers/article_html/article_form.html.heex` with the following contents:
```html
<.simple_form :let={f} for={@changeset} action={@action}>
<.error :if={@changeset.action}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={f[:title]} type="text" label="Title" />
<.input field={f[:body]} type="text" label="Body" />
<:actions>
<.button>Save Article</.button>
</:actions>
</.simple_form>
```
The above code is the same as our form in `lib/blog_web/controllers/article_html/new.html.heex`, except that `action` now uses `@action`.
Let's update `lib/blog_web/controllers/article_html/new.html.heex` to use the partial:
```html
<.header>
New Article
</.header>
<.article_form changeset={@changeset} action={~p"/articles"} />
```
And now, let's create a very similar app/views/articles/edit.html.erb:
```html
<.header>
Edit Article
</.header>
<.article_form changeset={@changeset} action={~p"/articles/#{@article}"} />
```
#### 7.4.2 Finishing Up
We can now update an article by visiting its edit page, e.g. http://localhost:4000/articles/1/edit. To finish up, let's link to the edit page from the bottom of `lib/blog_web/controllers/article_html/show.html.heex`:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul>
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
</ul>
```
### 7.5 Deleting an Article
Finally, we arrive at the "D" (Delete) of CRUD. Deleting a resource is a simpler process than creating or updating. It only requires a route and a controller action. And our resourceful routing (resources :articles) already provides the route, which maps DELETE /articles/:id requests to the destroy action of `ArticleController`.
```elixir
defmodule BlogWeb.ArticleController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Article
def index(conn, _params) do
articles = MyBlog.list_articles()
render(conn, :index, articles: articles)
end
def show(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
render(conn, :show, article: article)
end
def new(conn, _params) do
changeset = MyBlog.change_article(%Article{})
render(conn, :new, changeset: changeset)
end
def create(conn, %{"article" => article_params}) do
case MyBlog.create_article(article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article created successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
def edit(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
changeset = MyBlog.change_article(article)
render(conn, :edit, article: article, changeset: changeset)
end
def update(conn, %{"id" => id, "article" => article_params}) do
article = MyBlog.get_article!(id)
case MyBlog.update_article(article, article_params) do
{:ok, article} ->
conn
|> put_flash(:info, "Article updated successfully.")
|> redirect(to: ~p"/articles/#{article}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :edit, article: article, changeset: changeset)
end
end
def delete(conn, %{"id" => id}) do
article = MyBlog.get_article!(id)
{:ok, _article} = MyBlog.delete_article(article)
conn
|> put_flash(:info, "Article deleted successfully.")
|> redirect(to: ~p"/articles")
end
end
```
The newly added `delete` method in the controller uses a new method in the `MyBlog` context: `MyBlog.delete_article`. Let's add that now:
```elixir
defmodule Blog.MyBlog do
import Ecto.Query, warn: false
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
def get_article!(id) do
Repo.get!(Article, id)
end
def change_article(%Article{} = article, attrs \\ %{}) do
Article.changeset(article, attrs)
end
def create_article(attrs \\ %{}) do
%Article{}
|> Article.changeset(attrs)
|> Repo.insert()
end
def update_article(%Article{} = article, attrs) do
article
|> Article.changeset(attrs)
|> Repo.update()
end
def delete_article(%Article{} = article) do
Repo.delete(article)
end
end
```
The destroy action fetches the article from the database, and calls destroy on it. Then, it redirects the browser to the root path with status code 303 See Other.
We have chosen to redirect to the root path because that is our main access point for articles. But, in other circumstances, you might choose to redirect to e.g. `|> redirect(to: ~p"/articles")`.
Now let's add a link at the bottom of `lib/blog_web/controllers/article_html/show.html.heex` so that we can delete an article from its own page:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul>
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
<li>
<.link href={~p"/articles/#{@article}"} method="delete" data-confirm="Are you sure?">
Delete
</.link>
</li>
</ul>
```
And that's it! We can now list, show, create, update, and delete articles! InCRUDable!
### 8 Adding a Second Model
It's time to add a second model to the application. The second model will handle comments on articles.
### 8.1 Generating a Model
We're going to see the same generator that we used before when creating the Article model. This time we'll create a Comment model to hold a reference to an article. Run this command in your terminal:
```shell
$ mix phx.gen.context MyBlog Comment comments commenter:string body:text article_id:references:articles
```
It will ask you if you want to add functions to the existing context:
```shell
You are generating into an existing context.
The Blog.MyBlog context currently has 6 functions and 1 file in its directory.
* It's OK to have multiple resources in the same context as long as they are closely related. But if a context grows too large, consider breaking it apart
* If they are not closely related, another context probably works better
The fact two entities are related in the database does not mean they belong to the same context.
If you are not sure, prefer creating a new context over adding to the existing one.
Would you like to proceed? [Yn]
```
We want to put the new `Comments` model in the same context as the existing `Article` model. Press enter.
It will create new files and add to existing files:
```shell
* creating lib/blog/my_blog/comment.ex
* creating priv/repo/migrations/20240423232742_create_comments.exs
* injecting lib/blog/my_blog.ex
* creating test/blog/my_blog_test.exs
* injecting test/blog/my_blog_test.exs
* creating test/support/fixtures/my_blog_fixtures.ex
* injecting test/support/fixtures/my_blog_fixtures.ex
Remember to update your repository by running migrations:
$ mix ecto.migrate
```
> :warning: See what files are generated for each of the `mix phx.gen` commands [in the docs here](https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.html).
First, take a look at the `Comment` model, located at `lib/blog/my_blog/comment.ex`:
```elixir
defmodule Blog.MyBlog.Comment do
use Ecto.Schema
import Ecto.Changeset
schema "comments" do
field :body, :string
field :commenter, :string
field :article_id, :id
timestamps(type: :utc_datetime)
end
@doc false
def changeset(comment, attrs) do
comment
|> cast(attrs, [:commenter, :body])
|> validate_required([:commenter, :body])
end
end
```
In addition to the model, Pheonix has also made a migration to create the corresponding database table:
```elixir
defmodule Blog.Repo.Migrations.CreateComments do
use Ecto.Migration
def change do
create table(:comments) do
add :commenter, :string
add :body, :text
add :article_id, references(:articles, on_delete: :nothing)
timestamps(type: :utc_datetime)
end
create index(:comments, [:article_id])
end
end
```
The `article_id` field is used to reference the `id` field on the `articles` table.
Let's make one small change to the `on_delete` option for the `article_id` field to keep data consistent.
```elixir
defmodule Blog.Repo.Migrations.CreateComments do
use Ecto.Migration
def change do
create table(:comments) do
add :commenter, :string
add :body, :text
add :article_id, references(:articles, on_delete: :delete_all)
timestamps(type: :utc_datetime)
end
create index(:comments, [:article_id])
end
end
```
This will help keep out database clean, so when an article gets deleted, the associated comments for that article also gets deleted. The `delete_all` option will prevent comments from existing in the database without an article existing.
Go ahead and run the migration:
```shell
mix ecto.migrate
```
Phoenix is smart enough to only execute the migrations that have not already been run against the current database, so in this case you will just see:
```shell
Generated blog app

```
### 8.2 Associating Models
Ecto associations let you easily declare the relationship between two models. In the case of comments and articles, you could write out the relationships this way:
- Each comment belongs to one article.
- One article can have many comments.
In fact, this is very close to the syntax that Ecto uses to declare this association. Let's modify the `Comment` model to make each comment belong_to an `Article`:
Update the `Comment` model located at `lib/blog/my_blog/comment.ex` with this:
```elixir
defmodule Blog.MyBlog.Comment do
use Ecto.Schema
import Ecto.Changeset
alias Blog.MyBlog.Article
schema "comments" do
field :body, :string
field :commenter, :string
belongs_to :article, Article
timestamps(type: :utc_datetime)
end
@doc false
def changeset(comment, attrs) do
comment
|> cast(attrs, [:commenter, :body, :article_id])
|> validate_required([:commenter, :body])
|> assoc_constraint(:article)
end
end
```
You'll need to edit `lib/blog/my_blog/article.ex` to add the other side of the association:
```elixir
defmodule Blog.MyBlog.Article do
use Ecto.Schema
import Ecto.Changeset
alias Blog.MyBlog.Comment
schema "articles" do
field :title, :string
field :body, :string
has_many :comments, Comment
timestamps(type: :utc_datetime)
end
@doc false
def changeset(article, attrs) do
article
|> cast(attrs, [:title, :body])
|> validate_required([:title, :body])
|> validate_length(:body, min: 10)
end
end
```
> :warning: For more information on Ecto associations, see the [Ecto Assocations](https://hexdocs.pm/ecto/2.2.11/associations.html#one-to-many) guide.
Let's test the relationship in `iex`:
```shell
$ iex -S mix
[info] Migrations already up
Interactive Elixir (1.14.3) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)>
```
First create a new article:
```shell
iex(1)> alias Blog.MyBlog.Article
Blog.MyBlog.Article
iex(2)> article = %Article{title: "My test article", body: "Has many comments"}
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:built, "articles">,
id: nil,
body: "Has many comments",
title: "My test article",
inserted_at: nil,
updated_at: nil
}
iex(3)> alias Blog.Repo
Blog.Repo
iex(4)> article = Repo.insert!(article)
[debug] QUERY OK source="articles" db=9.6ms idle=1008.4ms
INSERT INTO "articles" ("body","title","inserted_at","updated_at") VALUES (?,?,?,?) RETURNING "id" ["Has many comments", "My test article", ~U[2024-04-23 23:53:05Z], ~U[2024-04-23 23:53:05Z]]
↳ anonymous fn/4 in :elixir.eval_external_handler/1, at: src/elixir.erl:309
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 4,
title: "My test article",
body: "Has many comments",
comments: #Ecto.Association.NotLoaded<association :comments is not loaded>,
inserted_at: ~U[2024-04-24 00:09:21Z],
updated_at: ~U[2024-04-24 00:09:21Z]
}
```
Then let's create a comment for the article we just created:
```shell
iex(11)> comment = Ecto.build_assoc(article, :comments, %{commenter: "First commenter", body: "Sweet article"})
%Blog.MyBlog.Comment{
__meta__: #Ecto.Schema.Metadata<:built, "comments">,
id: nil,
body: "Sweet article",
commenter: "First commenter",
article_id: 5,
article: #Ecto.Association.NotLoaded<association :article is not loaded>,
inserted_at: nil,
updated_at: nil
}
iex(12)> Repo.insert!(comment)
[debug] QUERY OK source="comments" db=0.4ms idle=1273.9ms
INSERT INTO "comments" ("article_id","body","commenter","inserted_at","updated_at") VALUES (?,?,?,?,?) RETURNING "id" [5, "Sweet article", "First commenter", ~U[2024-04-24 00:12:35Z], ~U[2024-04-24 00:12:35Z]]
↳ anonymous fn/4 in :elixir.eval_external_handler/1, at: src/elixir.erl:309
%Blog.MyBlog.Comment{
__meta__: #Ecto.Schema.Metadata<:loaded, "comments">,
id: 1,
body: "Sweet article",
commenter: "First commenter",
article_id: 5,
article: #Ecto.Association.NotLoaded<association :article is not loaded>,
inserted_at: ~U[2024-04-24 00:12:35Z],
updated_at: ~U[2024-04-24 00:12:35Z]
}
```
Let's see if it worked:
```shell
iex(14)> Repo.get(Article, article.id) |> Repo.preload(:comments)
[debug] QUERY OK source="articles" db=0.0ms queue=0.2ms idle=1774.5ms
SELECT a0."id", a0."title", a0."body", a0."inserted_at", a0."updated_at" FROM "articles" AS a0 WHERE (a0."id" = ?) [5]
↳ anonymous fn/4 in :elixir.eval_external_handler/1, at: src/elixir.erl:309
[debug] QUERY OK source="comments" db=0.0ms queue=0.1ms idle=1781.4ms
SELECT c0."id", c0."body", c0."commenter", c0."article_id", c0."inserted_at", c0."updated_at", c0."article_id" FROM "comments" AS c0 WHERE (c0."article_id" = ?) ORDER BY c0."article_id" [5]
↳ anonymous fn/4 in :elixir.eval_external_handler/1, at: src/elixir.erl:309
%Blog.MyBlog.Article{
__meta__: #Ecto.Schema.Metadata<:loaded, "articles">,
id: 5,
title: "My test article",
body: "Has many comments",
comments: [
%Blog.MyBlog.Comment{
__meta__: #Ecto.Schema.Metadata<:loaded, "comments">,
id: 1,
body: "Sweet article",
commenter: "First commenter",
article_id: 5,
article: #Ecto.Association.NotLoaded<association :article is not loaded>,
inserted_at: ~U[2024-04-24 00:12:35Z],
updated_at: ~U[2024-04-24 00:12:35Z]
}
],
inserted_at: ~U[2024-04-24 00:12:10Z],
updated_at: ~U[2024-04-24 00:12:10Z]
}
```
In the example above, Ecto.build_assoc received an existing article struct, that was already persisted to the database, and built a `Comment` struct, based on its `:comments` association, with the `article_id` foreign key field properly set to the ID in the article struct.
## 8.3 Adding a Route for Comments
As with the articles controller, we will need to add a route so that Phoenix knows where we would like to navigate to see comments. Open up the `lib/blog/router.ex` file again, and edit it as follows:
```elixir
scope "/", BlogWeb do
pipe_through :browser
get "/", ArticleController, :index
resources "/articles", ArticleController do
resources "/comments", CommentController
end
end
```
This creates comments as a nested resource within articles. This is another part of capturing the hierarchical relationship that exists between articles and comments.
### 8.4 Generating a Controller
With the model in hand, you can turn your attention to creating a matching controller. Again, we'll create it by hand by creating a new, empty file at `lib/blog_web/controllers/comment_controller.ex`.
Let's first wire up the Article show template (`lib/blog_web/controllers/article_html/show.html.heex`) to let us create a new comment:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul>
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
<li>
<.link href={~p"/articles/#{@article}"} method="delete" data-confirm="Are you sure?">
Delete
</.link>
</li>
</ul>
<p>
<.simple_form :let={f} for={@comment_changeset} action={~p"/articles/#{@article}/comments"}>
<.error :if={@comment_changeset.action}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={f[:commenter]} type="text" label="Commenter" />
<.input field={f[:body]} type="text" label="Body" />
<:actions>
<.button>Create Comment</.button>
</:actions>
</.simple_form>
</p>
```
This adds a form on the `Article` show page that creates a new comment by calling the `CommentController` create action.
Let's wire up the `create` in `lib/blog/blog_web/controllers/comment_controller.ex`:
```elixir
defmodule BlogWeb.CommentController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Comment
def create(conn, %{"comment" => comment_params, "article_id" => article_id} = params) do
case MyBlog.create_comment(Map.merge(comment_params, %{"article_id" => article_id})) do
{:ok, comment} ->
conn
|> put_flash(:info, "Comment created successfully.")
|> redirect(to: ~p"/articles/#{comment.article_id}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
end
```
You'll see a bit more complexity here than you did in the controller for articles. That's a side-effect of the nesting that you've set up. Each request for a comment has to keep track of the article to which the comment is attached, thus the `article_id` must be merged to the `comment_params` map to make the association betwen the comment and the article.
Once we have made the new comment, we send the user back to the original article using the `redirect(to: ~p"/articles/#{comment.article_id}")` helper. As we have already seen, this calls the show action of the `ArticleController` which in turn renders the show.html.heex template. This is where we want the comment to show, so let's add that to the `lib/blog_web/controllers/article_html/show.html.heex`:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul class="py-2">
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
<li>
<.link href={~p"/articles/#{@article}"} method="delete" data-confirm="Are you sure?">
Delete
</.link>
</li>
</ul>
<h2 class="text-md text-brand">
Comments
</h2>
<%= for comment <- @article.comments do %>
<div class="py-2">
<p>
<strong>Commenter:</strong>
<%= comment.commenter %>
</p>
<p>
<strong>Comment:</strong>
<%= comment.body %>
</p>
</div>

<p>
<.simple_form :let={f} for={@comment_changeset} action={~p"/articles/#{@article}/comments"}>
<.error :if={@comment_changeset.action}>
Oops, something went wrong! Please check the errors below.

<.input field={f[:body]} type="text" label="Body" />
<:actions>

</:actions>
</.simple_form>
</p>
```
Lastly to do is to `preload` the `comments` for the `@article`. Unlike other ORMs, Ecto does not allow lazy loading, meaning that all requests to the database must be explicit. Add `Repo.preload(:comments)` to the `get_article!` method in the `MyBlog` context in `lib/blog/my_blog/my_blog.ex`:
```elixir
defmodule Blog.MyBlog do
import Ecto.Query, warn: false
alias Blog.Repo
alias Blog.MyBlog.Article
def list_articles() do
Repo.all(Article)
end
def get_article!(id) do
Repo.get!(Article, id)
|> Repo.preload(:comments)
end
def change_article(%Article{} = article, attrs \\ %{}) do
Article.changeset(article, attrs)
end
def create_article(attrs \\ %{}) do
%Article{}
|> Article.changeset(attrs)
|> Repo.insert()
end
def update_article(%Article{} = article, attrs) do
article
|> Article.changeset(attrs)
|> Repo.update()
end
def delete_article(%Article{} = article) do
Repo.delete(article)
end
alias Blog.MyBlog.Comment
@doc """
Returns the list of comments.
## Examples
iex> list_comments()
[%Comment{}, ...]
"""
def list_comments do
Repo.all(Comment)
end
@doc """
Gets a single comment.
Raises `Ecto.NoResultsError` if the Comment does not exist.
## Examples
iex> get_comment!(123)
%Comment{}
iex> get_comment!(456)
** (Ecto.NoResultsError)
"""
def get_comment!(id), do: Repo.get!(Comment, id)
@doc """
Creates a comment.
## Examples
iex> create_comment(%{field: value})

iex> create_comment(%{field: bad_value})
{:error, %Ecto.Changeset{}}
"""
def create_comment(attrs \\ %{}) do
%Comment{}
|> Comment.changeset(attrs)
|> Repo.insert()
end
@doc """
Updates a comment.
## Examples
iex> update_comment(comment, %{field: new_value})
{:ok, %Comment{}}
iex> update_comment(comment, %{field: bad_value})
{:error, %Ecto.Changeset{}}
"""
def update_comment(%Comment{} = comment, attrs) do
comment
|> Comment.changeset(attrs)
|> Repo.update()
end
@doc """
Deletes a comment.
## Examples
iex> delete_comment(comment)

def delete_comment(%Comment{} = comment) do
Repo.delete(comment)
end
@doc """

def change_comment(%Comment{} = comment, attrs \\ %{}) do
Comment.changeset(comment, attrs)
end
end
```
Now try creating a new comment. You should be redirected back to the article show page, and see the newly created comment.
## 9 Refactoring
Now that we have articles and comments working, take a look at the `lib/blog_web/controllers/article_html/show.html.heex` template. It is getting long and awkward. We can use partials to clean it up.
### 9.1 Rendering Partial Collections
First, we will make a comment partial to extract showing all the comments for the article. Create the file `lib/blog_web/controllers/article_html/_comment.html.heex` and put the following into it:
```html
<div class="py-2">
<p>
<strong>Commenter:</strong>
<%= @comment.commenter %>
</p>
<p>
<strong>Comment:</strong>
<%= @comment.body %>
</p>
</div>
```
Then you can change `lib/blog_web/controllers/article_html/show.html.heex` to look like the following:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul class="py-2">
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
<li>
<.link href={~p"/articles/#{@article}"} method="delete" data-confirm="Are you sure?">
Delete
</.link>
</li>
</ul>
<h2 class="text-md text-brand">
Comments
</h2>
<%= for comment <- @article.comments do %>
<._comment comment={comment} />
<% end %>
<p>
<.simple_form :let={f} for={@comment_changeset} action={~p"/articles/#{@article}/comments"}>
<.error :if={@comment_changeset.action}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={f[:commenter]} type="text" label="Commenter" />
<.input field={f[:body]} type="text" label="Body" />
<:actions>
<.button>Create Comment</.button>
</:actions>
</.simple_form>
</p>
```
This will now render the partial in `lib/blog_web/controllers/article_html/_comment.html.heex` once for each comment that is in the `@article.comments` collection.
### 9.2 Rendering a Partial Form
Let us also move that new comment section out to its own partial. Again, you create a file `lib/blog_web/controllers/comment_html/_form.html.heex` containing:
```html
<.simple_form :let={f} for={@comment_changeset} action={~p"/articles/#{@article}/comments"}>
<.error :if={@comment_changeset.action}>
Oops, something went wrong! Please check the errors below.
</.error>
<.input field={f[:commenter]} type="text" label="Commenter" />
<.input field={f[:body]} type="text" label="Body" />
<:actions>
<.button>Create Comment</.button>
</:actions>
</.simple_form>
```
Then you make the `lib/blog_web/controllers/article_html/show.html.heex` look like the following:
```html
<h1 class="text-lg text-brand">
<%= @article.title %>
</h1>
<p><%= @article.body %></p>
<ul class="py-2">
<li>
<.link navigate={~p"/articles/#{@article}/edit"}>Edit</.link>
</li>
<li>
<.link href={~p"/articles/#{@article}"} method="delete" data-confirm="Are you sure?">
Delete
</.link>
</li>
</ul>
<h2 class="text-md text-brand">
Comments
</h2>
<%= for comment <- @article.comments do %>
<._comment comment={comment} />
<% end %>
<p>
<._form comment_changeset={@comment_changeset} article={@article} />
</p>
```
Lastly, we need to update `lib/blog_web/article_html.ex` to include the form template in the new `comment` directory:
```elixir
defmodule BlogWeb.ArticleHTML do
use BlogWeb, :html
embed_templates "article_html/*"
embed_templates "comment_html/*"
end
```
Refresh and the form should still work.
### 9.3 Sharing code between schemas
> Not sure of what the best way to implement this in Phoenix is actually.
## 10 Deleting Comments
Another important feature of a blog is being able to delete spam comments. To do this, we need to implement a link of some sort in the view and a destroy action in the `CommentController`.
So first, let's add the delete link in the `lib/blog_web/controllers/comment_html/_comment.html.heex` partial:
```html
<div class="py-2">
<p>
<strong>Commenter:</strong>
<%= @comment.commenter %>
</p>
<p>
<strong>Comment:</strong>
<%= @comment.body %>
</p>
</div>
<.link href={~p"/articles/#{@comment.article_id}/comments/#{@comment.id}"} method="delete" data-confirm="Are you sure?">
Delete Comment
</.link>
```
Clicking this new "Delete Comment" link will fire off a `DELETE /articles/:article_id/comments/:id` to our `CommentController`, which can then use this to find the comment we want to delete, so let's add a `delete` action to our controller (`lib/blog_web/controllers/comment_controller.ex`):
```elixir
defmodule BlogWeb.CommentController do
use BlogWeb, :controller
alias Blog.MyBlog
alias Blog.MyBlog.Comment
def create(conn, %{"comment" => comment_params, "article_id" => article_id} = params) do
case MyBlog.create_comment(Map.merge(comment_params, %{"article_id" => article_id})) do
{:ok, comment} ->
conn
|> put_flash(:info, "Comment created successfully.")
|> redirect(to: ~p"/articles/#{comment.article_id}")
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, :new, changeset: changeset)
end
end
def delete(conn, %{"article_id" => article_id, "id" => id}) do
comment = MyBlog.get_comment_for_article!(article_id, id)
{:ok, comment} = MyBlog.delete_comment(comment)
conn
|> put_flash(:info, "Comment deleted successfully.")
|> redirect(to: ~p"/articles/#{comment.article_id")
end
end
```
The destroy action will find the comment we are looking at in the article's comments, and then remove it from the database and send us back to the show action for the article.
Let's add the new context method `MyBlog.get_comment_for_article!` to the `MyBlog` context at `lib/blog/my_blog/my_blog.ex`:
```elixir
def get_comment_for_article!(article_id, comment_id) do
Repo.one(from c in Comment, where: c.article_id == ^article_id and c.id == ^comment_id)
end
```
Try deleting a comment now.

**Introduction: The Clash of the Coding Giants
**
On the constantly changing scene of programming, two languages have definitely taken center stage and attracted the ears and eyes of all developers, engineers, and generally, all the appreciated lovers of technology at large: Python and Java. These two juggernauts of programs have carved out specialized areas with rather special powers, capabilities, and cases of application.
With the growing demand of programmers in the industry, especially for web development, the debate between Python and Java has become very relevant. In this article, we will probe deeper into the intrinsics of these two programming languages. Each will explore their respective strengths and weaknesses—the things, in other words, that make them quite reasonable to handle different sorts of projects and applications.
**Python: The Versatile Powerhouse
**
Python is often called the "Swiss Army Knife" of programming languages. It envisions ease, readability, and multifariousness at large. This is very clean and intuitive; hence, its syntax makes it very easy for beginners and provides robust features and libraries for expert dev ends.
Another massive power of Python is the extensive number of libraries and frameworks available within its ecosystem, covering most various domains: data science, machine learning, and web development, to mention but a few. This thus puts a Python developer in a vantage position to build and deploy complex applications quickly without reinventing the wheel.
Moreover, Python's dynamic typing and interpreted nature make it exemplary for rapid prototyping, scripting, and data analysis tasks. The fact that this language easily works with other languages—C and C++—further increases its versatility in ways that let a developer take different languages' strengths all rolled up in a single project.
**Java: The Solid and Trustworthy Workhorse
**
While Java is a statically-typed, object-oriented programming language that became the pillar of the tech industry a number of decades ago. This explains its potency, scalability, and ability for cross-platform operation—not to mention that it has become a go-to option for enterprise-level applications, large-scale software systems, and mission-critical projects.
The main advantages of Java are strong type checking and compile-time error detection, which let it trace bugs at the very early stages of development. A rich standard library along with a huge ecosystem of third-party libraries available makes Java one of the premier choices for developing complex enterprise applications.
Moreover, the platform independence of Java on account of JVM is what allows one to write once and deploy it across an immense range of operating systems and hardware platforms. On that basis, cross-platform compatibility has enshrined Java at the top of the list of first preferences in developing applications for running across multiple systems, such as mobile apps, web applications, and distributed systems.
**Syntax and Readability: Simplicity vs. Verbosity
**
Another major difference is the_Syntax and Readability_ between Python and Java. Python has a clean, concise, and intuitive syntax. It emphasizes readability and simplicity. It is what makes Python code pretty easy to understand for any person familiar with it or even for beginners in programming, hence faster in development.
The syntax of Java is generally more verbose and explicit, thus laying emphasis on strict type checking with a more rigid structure. This might make the code lengthier, hence a bit harder to read, especially for beginners, but it provides a higher degree of type-safety that assists in catching errors at an earlier stage of development.
The choice between Python's simplicity and Java's verbosity mostly comes down to personal preference and the requirements of the project. Developers who believe in readability and fast prototyping can find themselves in a mix where Python is optimal, but those working on large-scale and enterprise-level applications find that Java's strict syntax and type checking are far more appropriate.
**Performance and Efficiency: Balancing Speed and Resource Utilization
**
For performance and efficiency, there are pros and cons to both languages. Since Java is a compiled language, it is radically faster and more efficient at runtime performance, mostly in computationally intensive tasks. This usually is laid at the feet of the just-in-time optimizations and compilation of the JVM.
On the other hand, Python is interpreted, making it generally slower in execution time as compared to C++. However, as a dynamic language, along with several high-performance libraries like NumPy and Pandas, Python throttles performance in domains like data analysis and scientific computing.
In terms of resource utilization, Java is much more efficient in terms of memory usage due to its static typing and primary compilation. This means Python will use up more memory and system resources to run programs, especially where large data sets or complex computations are involved.
While the choice between Python and Java PERFORMANCE and EFFECTIVENESS eventually comes down to the type of project and the kind of tasks involved, on the one hand, and required trade-offs between speed and resource utilisation and developer productivity, on the other.
**Web Development: Landscape of Python and Java
**
There is room for both Python and Java in the web development world; their role can be completely different.
Enriched with huge frameworks of web development like Django and Flask, Python has emerged as a go-to choice in developing dynamic, scalable, and feature-rich applications. The simplicity, rapidity of prototyping, and availability of tools that are very powerful for web development have made Python considerably attractive to web developers, especially in projects requiring a high degree of flexibility or customization.
On the other hand, enterprise-level Web development is dominated by Java, with frameworks like Spring and Java Server Faces of very wide applicability in constructing large-scale web applications that provide security and scalability. It is the first choice when it comes to high-performance, mission-critical web applications of organizations because of the robustness and availability of enterprise-grade features, great libraries, and tools.
Ultimately, the choice between Python and Java for web development depends on specific project requirements, the team's expertise, and the desired balance of ease of development, scalability, and enterprise features.
**How Web Development Courses Can Help You Master a Programming Language
**
It is because of the increasing demand for skilled web developers that comprehensive [web development courses](https://bostoninstituteofanalytics.org/full-stack-web-development/) have gained importance. Such a program would present aspiring developers with foundational knowledge and practical skills to navigate complex web development and master these languages, like Python and Java.
Web development courses expose students to the very latest tools, frameworks, and industry-standard best practices in Python and Java, with the additional advantage of hands-on projects, mentorship of industry experts, and opportunities giving them real-world exposure. The courses also combine theoretical knowledge with practical experience to make them fully grasp the underlying principles and techniques behind the world of web development.
Moreover, courses in web development will be able to offer the students further insights into involvement and career potential, hence allowing them to carve out areas they can specialize in and thus have a very clear roadmap of their further professional growth in that field.
**Conclusion: Choosing the Right Tool for the Job
**
In a world of continued evolution in programs, Python and Java have been the two major languages that evolved to be very influential and most used, each having its own strengths, weaknesses, and use cases. Knowing the nuisances of these programming giants could turn out to be a career-defining step, whether you are a seasoned developer or just entering the fray.
As you grow closer to the landscape of Web development and beyond, bear in mind that the choice between Python and Java should be based, in general, on your project's needs, the expertise of your team, and the right trade-off between development speed, scalability, and enterprise features. You can profit from learning through comprehensive web development courses to empower yourself with the knowledge and skills needed to make apt decisions and excel in the dynamic world of programming.

1,899,855 | What Are the Challenges and Applications of Large Language Models? | Introduction What are the challenges and applications of large language models?... | 0 | 2024-06-25T10:45:06 | https://dev.to/novita_ai/what-are-the-challenges-and-applications-of-large-language-models-2577 | llm | ## Introduction
What are the challenges and applications of large language models? Referencing the work "Challenges and Applications of Large Language Models" by Kaddour, J., Harris, J., Mozes, M., Bradley, H., Raileanu, R., & McHardy, R., this blog is going to discuss this question in a plain and simple way. Let's begin our exploration journey with a detailed explanation of what large language models are.
## What Are Large Language Models?
Large Language Models (LLMs) represent a significant advancement in natural language processing (NLP) within the realm of artificial intelligence. At their core, LLMs are sophisticated algorithms designed to understand, generate, and manipulate human language in a manner that simulates human-like comprehension and expression. These models are closely tied to the broader fields of deep learning, where they utilize neural networks with many layers (hence the term "deep learning") to process vast amounts of textual data and learn intricate patterns and relationships.
### Processing Text Data
LLMs and image or sound processing AI models share similarities in their overarching goal of processing specific types of data - textual, visual, and auditory - to perform tasks like understanding, generation, and classification. Both types of models leverage deep learning techniques, utilizing neural networks to learn patterns and features from their respective data domains. However, the key differences lie in their input data and the nature of the tasks they perform. LLMs, such as those based on Transformer architectures, excel in understanding and generating natural language text, utilizing mechanisms like attention to process sequences of words effectively. In contrast, image processing AI models typically involve convolutional neural networks (CNNs), which specialize in extracting spatial hierarchies and features from images, enabling tasks like object detection and image classification.
### Definition of Neural Network
Neural network layers play a crucial role in LLMs by enabling them to process and understand complex patterns in language data. A neural network is a type of computer program that learns and makes decisions, inspired by how our brains work. Imagine it as a series of connected boxes, where each box does a specific job. These boxes are called neurons.
Here's how it works:
1. Input: You start with some information, like numbers representing pixels in a picture or words in a sentence. These go into the first layer of neurons.
2. Processing: Each neuron in the first layer does some math with the input it gets. It passes its result to neurons in the next layer.
3. Layers: The network has multiple layers - each one taking the output from the previous layer and doing more math on it. These layers help the network to understand more complex things about the input.
4. Output: Finally, after passing through all the layers, the network gives you an answer. For example, it might tell you what object is in a picture or translate a sentence into another language.
5. Learning: Neural networks learn by adjusting how they do their math. They get better at their tasks by practicing with lots of examples. This adjustment happens automatically as the network gets more data and feedback.
### Neural Network and LLM Algorithms
Different neural network architectures vary significantly in their structure based on factors such as types of layers, connections between layers and depth and width of layers.
LLM algorithms, like those based on Transformer architectures, consist of multiple layers of interconnected nodes (neurons). Each layer in the network performs a specific task: lower layers capture basic patterns such as word sequences, while higher layers integrate these patterns into more abstract concepts like grammar rules or semantic meaning. This layered approach allows LLMs to learn hierarchical representations of language, where each layer refines and builds upon the representations learned by the previous layers. Ultimately, these layers work together to enhance the model's ability to generate coherent text, understand nuances in language, and perform various natural language processing tasks with high accuracy.
### Evolving LLM Algorithms
Traditionally, LLMs were built using algorithms like Recurrent Neural Networks (RNNs) or Long Short-Term Memory networks (LSTMs), which can handle sequential data and capture dependencies over time. However, modern LLMs have largely transitioned to Transformer architectures. Transformers, introduced by Vaswani et al. in 2017, revolutionized NLP with their ability to parallelize computation across sequences, making them highly efficient for processing large datasets. Popular examples of LLMs include OpenAI's GPT (Generative Pre-trained Transformer) series, Google's BERT (Bidirectional Encoder Representations from Transformers) and Meta AI's LLaMA series, which have set benchmarks in language understanding and generation tasks.
## What Are the Challenges in LLMs?
### Design Challenges
1. Unfathomable Datasets: The scale of data used for pre-training LLMs is often too vast for manual quality checks, leading to reliance on heuristics that can introduce biases or inaccuracies.
2. Tokenizer-Reliance: Tokenization processes can introduce computational overhead, language dependence, and information loss, affecting model performance.
3. High Pre-Training Costs: Training LLMs requires significant computational resources, which can be costly and energy-intensive.
4. Fine-Tuning Overhead: Adapting pre-trained models to specific tasks can be resource-intensive due to the large memory requirements of LLMs.
### Behavioral Challenges
1. Prompt Brittleness: Small changes in the input prompt can lead to significant variations in model output, affecting reliability.
2. Hallucinations: LLMs can generate factually incorrect information that is difficult to detect due to its fluent presentation.
3. Misaligned Behavior: Outputs may not align with human values or intentions, potentially leading to negative consequences.
### Science Challenges
1. Outdated Knowledge: LLMs may contain factual inaccuracies or outdated information that is costly to update.
2. Brittle Evaluations: The performance of LLMs can be uneven and sensitive to changes in evaluation protocols or prompts.
3. Lack of Reproducibility: The non-deterministic nature of training and inference in LLMs can make it difficult to reproduce results.

## How to Leverage the Power of LLMs for My Project?
The most efficient way to leverage the power of LLMs for your project is to integrate LLM API.
### Experiencing Multiple LLMs at A Time
Novita AI provides developers with [**LLM API**](https://novita.ai/llm-api) equipped with many LLM choices, including the trendy LLaMA series.
### Adjusting Parameters for Perfecting LLMs' Performances
Moreover, to cater to different needs, Novita AI offers personalized functions, e.g. parameter adjustment, system prompts input, and character import.
Parameter adjustment feature allows users to fine-tune various aspects of the AI's performance. For instance, you can adjust top P, temperature, max tokens and presence penalty.
**Top P:** Instead of selecting the most probable word (greedy selection), top P sampling restricts the model's choice to the top P percentage of the probability mass.
**Temperature:** A lower temperature (less than 1) makes the model's choices sharper, favoring more probable words and resulting in more conservative, predictable text. A higher temperature (greater than 1) increases the randomness, allowing the model to explore less likely word choices and potentially generate more creative or diverse text.
**Max Tokens:** This parameter sets a hard limit on the length of the output generated by the model, measured in the number of tokens (words or subwords, depending on the model's tokenizer).
**Presence Penalty:** The presence penalty is designed to reduce repetitiveness in the model's generated text by penalizing the repeated selection of words. It works by increasing the effective probability of other words in the vocabulary, thus encouraging the model to use a wider variety of vocabulary and avoid repeating the same words or phrases.
### Inputting System Prompts for Specific Scenarios
With Novita AI LLM API, users have the ability to input custom prompts or cues that the AI can recognize and respond to. This is particularly useful for users who want the AI to integrate seamlessly with their workflow or to create a more immersive role-playing experience. For example, a researcher might set up specific prompts related to their field of study, while a writer could use prompts to generate ideas for their next novel.
### Importing Character for More Fun
For users who enjoy role-playing or who want a more personalized interaction, the character import function of Novita AI's LLM API enables them to upload a profile or set of characteristics for the AI to adopt. The AI then uses this information to engage in a more character-specific dialogue, providing a unique and immersive experience.

1,899,993 | Redes: Datagrama | Introdução No mundo das redes de computadores, o termo "datagrama" ocupa um papel... | 0 | 2024-06-25T10:55:27 | https://dev.to/iamthiago/redes-datagrama-4p42 | ## Introdução
No mundo das redes de computadores, o termo "datagrama" ocupa um papel fundamental. Frequentemente associado ao protocolo IP (Internet Protocol), o datagrama é a unidade básica de transferência de dados. Este artigo explora o conceito de datagrama, sua estrutura, funcionamento, e importância na comunicação em rede.
## O Que é um Datagrama?
Um datagrama é um pacote de dados enviado em uma rede que contém informações suficientes para ser roteado do emissor ao receptor sem a necessidade de conexões pré-estabelecidas entre os pontos. Em termos simples, ele pode ser visto como uma mensagem encapsulada que viaja de um ponto a outro na rede.
### Estrutura de um Datagrama
Um datagrama é composto por duas partes principais: o cabeçalho e a carga útil.
1. **Cabeçalho**: Contém informações de controle e roteamento, como endereços IP de origem e destino, número de sequência, e outras informações que auxiliam no correto encaminhamento do datagrama.
2. **Carga Útil**: É a parte dos dados efetivamente transmitidos, que pode variar de acordo com o tipo e a necessidade da aplicação que está utilizando a rede.
### Funcionamento
Quando um datagrama é enviado pela rede, ele é encaminhado de roteador em roteador até alcançar seu destino final. Cada roteador lê o cabeçalho do datagrama para decidir qual o próximo salto na rota. Diferentemente de protocolos orientados à conexão, como o TCP, os datagramas são enviados sem a necessidade de estabelecer uma conexão prévia entre o emissor e o receptor.
## Vantagens e Desvantagens
### Vantagens
1. **Eficiência**: O encaminhamento de datagramas pode ser mais eficiente em redes onde a topologia muda com frequência, como em redes móveis.
2. **Simplicidade**: A ausência de uma conexão pré-estabelecida simplifica a transmissão de dados.
3. **Escalabilidade**: Protocolo sem estado (stateless), o que facilita a escalabilidade das redes.
### Desvantagens
1. **Confiabilidade**: Datagramas podem se perder ou chegar fora de ordem, exigindo mecanismos adicionais para garantir a entrega correta dos dados.
2. **Controle de Fluxo**: Não há um controle de fluxo embutido, o que pode levar à congestão em redes de alta demanda.
## Casos de Uso
Os datagramas são amplamente utilizados em diversos protocolos e aplicações, como:
1. **Protocolo IP**: A base da comunicação na Internet.
2. **UDP (User Datagram Protocol)**: Utilizado em aplicações que requerem baixa latência e podem tolerar a perda de alguns pacotes, como streaming de vídeo e jogos online.
3. **ICMP (Internet Control Message Protocol)**: Utilizado para enviar mensagens de erro e operações de diagnóstico, como o comando `ping`.
## Conclusão
Entender o funcionamento dos datagramas é essencial para qualquer profissional ou entusiasta da área de redes de computadores. Eles são a base sobre a qual a Internet é construída, proporcionando um método eficiente e escalável para a transferência de dados. A simplicidade e a flexibilidade dos datagramas garantem sua relevância contínua no cenário tecnológico em constante evolução.

1,899,991 | Balancing Security and Usability: Ensuring Effective Information Security without Overburdening Employees | There is a fine line between adequate security measures and overbearing security protocols that can... | 0 | 2024-06-25T10:53:36 | https://dev.to/borisgigovic/balancing-security-and-usability-ensuring-effective-information-security-without-overburdening-employees-26h9 | computersecurity, networksecurity, cyberawareness, securitypractices | There is a fine line between adequate security measures and overbearing security protocols that can lead to employee fatigue and decreased productivity. Striking the right balance—implementing just enough security to protect critical data without overwhelming employees—is essential for creating a secure yet efficient workplace. This article explores the concept of balanced security, the implications of excessive security measures, and strategies to maintain an optimal security posture.
# The Concept of Balanced Security
Balanced security refers to the implementation of security measures that adequately protect an organization’s information assets while ensuring that these measures do not interfere excessively with employees’ daily tasks. It is about finding the sweet spot where security protocols are strong enough to prevent breaches but not so cumbersome that they hinder productivity or cause frustration among staff.
Excessive security measures can manifest in various ways, such as frequent password changes, multi-layer authentication for routine tasks, overly restrictive access controls, and continuous monitoring that invades employees' privacy. While each of these measures individually might be justified, their collective impact can lead to what is known as "security fatigue."
# Security Fatigue: The Consequence of Overbearing Measures
Security fatigue occurs when employees become overwhelmed by the complexity and frequency of security requirements, leading to a decrease in their adherence to these protocols. This fatigue can result in risky behaviors such as reusing passwords, circumventing security procedures, or ignoring security alerts, ironically increasing the organization's vulnerability to threats.
For example, requiring employees to change their passwords every 30 days might seem like a good security practice. However, if the password policies are too stringent—demanding long, complex passwords without allowing the use of previous ones—employees might resort to writing them down or using easily guessable patterns, thereby defeating the purpose of the policy.
# Implementing Just Enough Security
To avoid security fatigue, organizations should aim to implement security measures that are sufficient to protect their information assets without being excessively burdensome. Here are a few strategies to achieve this balance:
## 1. Risk-Based Approach
Adopt a risk-based approach to security. This means identifying and focusing on protecting the most critical assets and systems rather than applying the same level of security to all assets uniformly. For instance, while multi-factor authentication (MFA) might be essential for accessing sensitive financial systems, it might not be necessary for accessing less critical internal resources.
## 2. User-Friendly Authentication
Implement user-friendly authentication methods. Biometric authentication, single sign-on (SSO) solutions, and password managers can significantly reduce the burden on employees. These methods enhance security while simplifying the login process, reducing the need for frequent password changes.
## 3. Employee Training and Awareness
Regular training and awareness programs can help employees understand the importance of security measures and how to comply with them effectively. When employees are educated about the risks and the rationale behind security policies, they are more likely to adhere to them.
## 4. Adaptive Security Policies
Implement adaptive security policies that adjust based on the context and behavior of the user. For example, if an employee is accessing the network from a trusted device and location, the system might require less stringent authentication compared to an unknown device or location. This approach reduces unnecessary friction while maintaining security.
## 5. Regular Reviews and Feedback
Regularly review security policies and gather feedback from employees to identify pain points and areas for improvement. This feedback can inform adjustments to security measures, ensuring they remain effective without being overly intrusive.
# Examples of Balanced Security Measures
## Example 1: Password Policies
Instead of enforcing complex passwords that must be changed frequently, an organization could implement a policy requiring passwords to be changed every 90 days, combined with MFA for critical systems. This approach balances security and usability, reducing the likelihood of password fatigue.
## Example 2: Access Controls
Rather than applying the same access control measures across the board, an organization can use role-based access control (RBAC) to ensure that employees have access only to the information necessary for their roles. This minimizes unnecessary access restrictions and streamlines workflows.
## Example 3: Security Alerts
Overloading employees with security alerts can lead to alert fatigue, where important warnings might be ignored. By fine-tuning alert thresholds and ensuring that only relevant, actionable alerts are sent, organizations can maintain awareness without overwhelming employees.
# Conclusion
While robust security is essential for protecting an organization's information assets, it is equally important to avoid overburdening employees with excessive measures. By adopting a balanced approach, focusing on critical risks, and implementing user-friendly solutions, organizations can maintain strong security without compromising productivity and employee satisfaction. Strategic solutions such as [cybersecurity awareness training](https://www.eccentrix.ca/en/courses/information-security/cybersecurity-awareness-for-users-cs8525) can also help in reducing risks and finding the balance between security and productivity.

We will discuss the advantages of using a moisturiser pump, its safety features, and how to use it correctly.
Top features of Making Use Of a Moisturiser Pump
The advantage which is main of a moisturizer pump is the known fact that it will also help prevent wastage.
A tendency is had by us to dispense significantly more than what’s needed once we use moisturizer or lotions which come in pipes or jars.
This overuse contributes to wastage for the item and money.
A moisturiser pump dispenses a fixed amount of item, making sure you use the ideal amount regarding the other hand.

1,899,810 | What Is Cumulative Reasoning With Large Language Models? | Introduction What is cumulative reasoning with large language models? Why do we need... | 0 | 2024-06-25T10:45:07 | https://dev.to/novita_ai/what-is-cumulative-reasoning-with-large-language-models-42la | llm | ## Introduction
What is cumulative reasoning with large language models? Why do we need cumulative reasoning for LLMs? What does cumulative reasoning with LLMs look like? Can LLMs Do Cumulative Reasoning Well? In this blog, we will discuss these questions one by one in a plain and simple way, referencing the paper titled "Cumulative Reasoning with Large Language Models" by Yifan Zhang, Jingqin Yang, Yang Yuan and Andrew Chi-Chih Yao.
## What Is Cumulative Reasoning?
The core idea behind the cumulative reasoning framework is to break down complex reasoning problems into smaller steps, and then iteratively build up the final solution by accumulating and verifying each intermediate step.
Drawing inspiration from human cognitive processes, cumulative reasoning introduces specialized roles like the "proposer" to suggest potential reasoning steps, "verifiers" to validate proposals against context, and a "reporter" to synthesize accumulated points into a final solution.
Cumulative reasoning enables the dynamic storage and composition of verified intermediate propositions, forming a directed acyclic graph (DAG).
Specifically, in the cumulative reasoning framework:
1. The proposer suggests potential reasoning steps based on the current context, which are represented as new nodes in the DAG.
2. The verifier(s) evaluate whether the proposer's suggestions are correct and incorporate valid steps into the evolving solution context, which corresponds to adding new directed edges to the DAG.
3. The reporter determines whether the accumulated context has reached a final solution based on the current state. If so, it outputs the result.
Therefore, the entire reasoning process can be represented as a dynamically constructed DAG, where nodes are intermediate reasoning steps, and directed edges capture how new reasoning steps are derived from previous ones. The DAG allows the reasoning process to branch out and reconverge, and enables revisiting and reusing previous reasoning results, better mirroring the flexible multi-path thinking process of humans in solving complex problems.
## Why Do We Need Cumulative Reasoning for LLMs?
Despite recent advancements of large language models (LLMs) in various applications, their ability to solve complex, multi-step reasoning problems remains limited. Existing methods like Chain-of-Thought (CoT) and Tree-of-Thought (ToT) prompting, though attempting to guide LLMs through a more structured step-by-step reasoning process, lack dynamic mechanisms for storing and leveraging intermediate results generated during the reasoning process. This inability to effectively build upon and compose previous propositions restricts their performance on intricate, multi-faceted problems requiring nuanced reasoning over multiple steps.
Drawing inspiration from human cognitive processes, cumulative reasoning introduces specialized roles like the "proposer" to suggest potential reasoning steps, "verifiers" to validate proposals against context, and a "reporter" to synthesize accumulated points into a final solution. This decomposition into iterative cycles of proposal, verification, and reporting allows LLMs to break down complex tasks into manageable components.
Crucially, cumulative reasoning enables the dynamic storage and composition of verified intermediate propositions, forming a directed acyclic graph (DAG) rather than just a linear chain or tree structure. This structural flexibility to leverage a broader context of previous validations mirrors the nuanced, non-linear reasoning employed by humans to tackle complex multi-step problems. As such, cumulative reasoning unlocks more robust and versatile reasoning capabilities for large language models.
## What Does Cumulative Reasoning With LLMs Look Like?
### Constructing Language Model Roles
Following the Cumulative Reasoning framework, the authors constructed three language model roles:
- Proposer: Suggests potential reasoning steps based on the current context
- Verifier: Evaluates the proposer's suggestions for correctness and incorporates valid steps into the context
- Reporter: Determines whether the accumulated context leads to a definitive solution
These three roles can use the same large language model, with specific prompts to assign different roles.
### Setting Up Baselines
To evaluate the effectiveness of Cumulative Reasoning, the authors set up the following baselines:
- Direct input-output prompting (Direct)
- Chain-of-Thought prompting (CoT)
- Self-Verified Chain-of-Thought prompting (CoT-SC)
- Tree-of-Thought prompting (ToT)
### Following Experiment Procedures
The authors tested various large language models, including GPT-3.5, GPT-4, and LLaMA models. The experiment procedures are as follows:
- For each problem in a dataset, input the problem to the proposer
- The proposer generates a series of reasoning suggestions as intermediate steps
- Feed the intermediate steps to the verifier, which evaluates each step
- Valid steps are incorporated into the context, while invalid steps are discarded
- Repeat the above process until the reporter determines a final solution can be given
- In some experiments, majority voting or other strategies are used to improve robustness
### Selecting Evaluation Datasets
The authors selected multiple datasets across different types of complex reasoning tasks for evaluation, including:
- Logical inference tasks: FOLIO wiki dataset, AutoTNLI dataset
- Game of 24 math puzzle
- Math problem solving: MATH dataset
## Can LLMs Do Cumulative Reasoning Well?
The simple answer is: Yes! The experimental results demonstrate that the CR framework significantly outperforms baseline methods across all evaluated tasks.
### Overall Performance
On the FOLIO wiki dataset, it improves accuracy from 85.02% to 98.04%; on the AutoTNLI dataset, it shows up to 9.3% relative improvement over Chain-of-Thought; in the Game of 24, it achieves 98% accuracy, marking a 24% improvement over the prior best method; on the MATH dataset, CR obtains a 4.2% absolute improvement and a 43% relative gain on the most challenging level 5 problems. Notably, by integrating CR with a code environment, the authors achieve 72.2% accuracy on the MATH dataset, outperforming the previous best by 38.8% relatively.
### Superiority Over Chain of Thought (CoT) and Tree of Thought (ToT)
Cumulative Reasoning (CR) demonstrates its superiority over Chain of Thought (CoT) and Tree of Thought (ToT) through a series of empirical results across various tasks. On logical inference tasks using datasets like FOLIO wiki and AutoTNLI, CR showed remarkable performance, achieving a 98.04% accuracy rate on the curated FOLIO dataset, which is a notable leap from CoT-SC's 96.09%. This advancement is attributed to CR's ability to dynamically store and leverage intermediate results, forming a Directed Acyclic Graph (DAG) that allows for a broader context of validated propositions.
In the Game of 24, a mathematical puzzle, CR excelled with a 98% accuracy rate, improving upon ToT by 24% and doing so with only a quarter of the visited states, underscoring its efficiency and problem-solving prowess.
Furthermore, on the MATH dataset, CR not only set new benchmarks with a 4.2% increase over previous methods but also showed a 43% relative improvement on the most difficult problems. The integration of CR with a Python code environment led to a striking 72.2% accuracy, outperforming methods like PoT and PAL by 38.8%. These results collectively illustrate the adaptability, robustness, and enhanced reasoning capabilities of CR in comparison to CoT and ToT.
## What Are the Future Directions of Cumulative Reasoning With LLMs?
### Integration with Symbolic Systems
The article discusses the potential of combining CR with a Python code environment to harness the computational and logical reasoning capabilities of LLMs. Future work could explore deeper integration with symbolic systems, knowledge graphs, or formal theorem provers to further enhance reasoning accuracy and complexity.
### Enhancing Generalization Capabilities
While CR has shown success in specific domains, extending its generalization capabilities to a broader range of tasks and domains will be crucial. This could involve adapting CR to handle different types of reasoning and problem-solving across various disciplines.
### Increasing Robustness and Error Tolerance
The article highlights the error-tolerant nature of CR. Future work could focus on making CR even more robust, especially in handling ambiguous or noisy data, and improving its ability to recover from incorrect intermediate steps.
### Benchmarking and Standardization
Developing standardized benchmarks and evaluation metrics specifically for cumulative reasoning tasks could help in systematically assessing the progress and comparing different approaches.
## How Can I Implement Cumulative Reasoning With Large Language Models?
Most codes provided by the authors require a connection to OpenAI API for GPT 3.5 and 4 models, which should be your first step.
Next, whether you want to solve math problems, play Game 24, or replicate cumulative reasoning experiments, just run the specific Python files provided on this Github page: https://github.com/iiis-ai/cumulative-reasoning.
In addition, if you want to test cumulative reasoning with LLaMA models like the authors did in the paper or with other LLMs, you can use [Novita AI LLM API](https://novita.ai/llm-api) to access multiple LLMs.
## Conclusion
In conclusion, the blog post has offered a comprehensive overview of cumulative reasoning with LLMs, a novel approach that significantly enhances the complex problem-solving abilities of LLMs. By dissecting complex problems into smaller steps and iteratively building up solutions through a process of proposal, verification, and reporting, cumulative reasoning mirrors human cognitive strategies.
The results from various datasets were impressive, showing substantial improvements in accuracy, especially when cumulative reasoning was integrated with a code environment. What's more, the results demonstrated the superiority of cumulative reasoning over existing methods like Chain-of-Thought and Tree-of-Thought.
Overall, the future directions of cumulative reasoning with LLMs hold the potential to propel LLMs to new heights in AI reasoning, leading to more sophisticated and human-like problem-solving capabilities.

1,899,967 | Building Your First Web Application with Flask: A Step-by-Step Guide | Flask is a lightweight web framework for Python, making it easy to get started with web development.... | 0 | 2024-06-25T10:29:21 | https://dev.to/zaiba_sa/building-your-first-web-application-with-flask-a-step-by-step-guide-5p8 | flask, python, webdev, webapp | Flask is a lightweight web framework for Python, making it easy to get started with web development. In this guide, we'll create a simple web application using Flask and the command line.
**Step 1: Install Flask**
First, ensure you have Python installed. You can check by running:
python --version
Next, install Flask using pip:
pip install Flask
**Step 2: Set Up Your Project**
Create a directory for your project:
mkdir my_flask_app
cd my_flask_app
Create a virtual environment to manage dependencies:
python -m venv venv
source venv/bin/activate # On Windows, use `venv\Scripts\activate`
**Step 3: Create the Flask Application**
Create a file named app.py and open it in your text editor:
touch app.py
Add the following code to app.py:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return "Hello, Flask!"
if __name__ == "__main__":
app.run(debug=True)
This code sets up a basic Flask application with a single route (/) that returns "Hello, Flask!".
**Step 4: Run Your Flask Application**
To run your Flask application, use the following command:
python app.py
You should see output indicating that the Flask development server is running. Open your web browser and go to http://127.0.0.1:5000/ to see the "Hello, Flask!" message.
**Step 5: Add More Routes**
Let's add another route to our application. Update app.py to include a new route:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
return "Hello, Flask!"
@app.route('/about')
def about():
return "This is the about page."
if __name__ == "__main__":
app.run(debug=True)
Now, if you visit http://127.0.0.1:5000/about, you'll see the message "This is the about page."
**Step 6: Use Templates**
To serve HTML content, Flask uses templates. Create a directory named templates:
mkdir templates
Create a file named home.html inside the templates directory:
touch templates/home.html
Add the following HTML content to home.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Home</title>
</head>
<body>
<h1>Hello, Flask!</h1>
</body>
</html>
Update app.py to render this template:
from flask import Flask, render_template
app = Flask(__name__)
@app.route('/')
def home():
return render_template('home.html')
@app.route('/about')
def about():
return "This is the about page."
if __name__ == "__main__":
app.run(debug=True)
Now, visiting http://127.0.0.1:5000/ will render the HTML content from home.html.
**Step 7: Add Static Files**
Flask also supports static files like CSS and JavaScript. Create a directory named static:
mkdir static
Create a CSS file named style.css inside the static directory:
touch static/style.css
Add some CSS to style.css:
body {
font-family: Arial, sans-serif;
}
h1 {
color: #333;
}
Update home.html to include this CSS file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Home</title>
<link rel="stylesheet" href="{{ url_for('static', filename='style.css') }}">
</head>
<body>
<h1>Hello, Flask!</h1>
</body>
</html>
Conclusion
Congratulations! You've built a simple web application using Flask. You've learned how to:
Set up a Flask project
Create routes
Serve HTML templates
Include static files
Flask is a powerful and flexible framework. From here, you can explore more advanced features such as form handling, database integration, and user authentication.

1,899,965 | what is chatgpt | ChatGPT stands as a testament to the remarkable progress in artificial intelligence, specifically... | 0 | 2024-06-25T10:24:35 | https://dev.to/whatischatgpt/what-is-chatgpt-3mpn | ChatGPT stands as a testament to the remarkable progress in artificial intelligence, specifically within the domain of natural language processing (NLP). Developed by OpenAI, ChatGPT embodies the latest advancements in deep learning, leveraging a transformative neural network architecture known as transformers. This model represents a culmination of research efforts aimed at creating machines capable of understanding and generating human-like text with unprecedented accuracy and coherence.
At its core, ChatGPT operates as an autoregressive language model. This means it learns to predict the next word in a sequence based on the words that precede it. Through extensive training on vast datasets sourced from the internet, comprising a diverse array of text ranging from books and articles to websites and social media posts, ChatGPT acquires a deep understanding of language patterns, semantics, syntax, and contextual nuances. This pre-training phase equips ChatGPT with the foundational knowledge necessary to generate contextually relevant responses across a wide spectrum of topics and conversational contexts.
The architecture of ChatGPT is built upon transformers, a type of neural network architecture that has revolutionized NLP. Transformers introduce a mechanism known as self-attention, allowing the model to weigh the relevance of different words in a sentence dynamically. This attention to context and dependency relationships between words enables ChatGPT to capture complex linguistic structures and generate text that not only mimics human speech but also exhibits a level of coherence and fluency previously unseen in machine-generated language.
One of the distinguishing features of ChatGPT is its scalability and versatility. The model is trained on increasingly larger datasets and more sophisticated algorithms, enabling it to handle a broad range of tasks beyond simple text generation. This includes language translation, summarization of documents, question answering, sentiment analysis, and more advanced forms of natural language understanding and generation. As a result, ChatGPT has become a versatile tool with applications across various industries, including education, healthcare, customer service, content creation, and beyond.
In practical terms, interacting with ChatGPT is akin to conversing with a knowledgeable and articulate counterpart. Users can input queries, prompts, or statements, and ChatGPT responds with text that is contextually appropriate and coherent. This capability makes ChatGPT invaluable in scenarios where natural language communication is essential, such as virtual assistants, chatbots, tutoring systems, and automated customer support services.
However, the development and deployment of ChatGPT also raise important ethical considerations and challenges. As with any advanced AI technology, there are concerns regarding bias in training data, the potential for misuse or manipulation (such as generating fake news or harmful content), and the ethical implications of AI-driven decision-making. Addressing these concerns requires ongoing research, transparency in AI development practices, and robust frameworks for responsible AI deployment to mitigate risks and ensure the ethical use of AI technologies like ChatGPT.
Looking forward, the future of [what is ChatGPT ](https://sodm.in/chatgpt/)holds exciting possibilities for further innovation and integration into everyday applications. Researchers are exploring avenues to enhance the model's capabilities, including improving its understanding of context, incorporating multimodal inputs (such as text and images), and integrating it with other AI technologies like computer vision and robotics. These advancements aim to create more intelligent and adaptive systems that can not only understand and generate text but also interact with and perceive the world in more sophisticated ways.
In conclusion, ChatGPT represents a groundbreaking achievement in the field of artificial intelligence and natural language processing. Its ability to understand and generate human-like text marks a significant milestone in the quest to develop machines that can communicate and interact with humans in meaningful and nuanced ways. As ChatGPT continues to evolve and expand its capabilities, it promises to reshape industries, empower businesses and individuals, and pave the way for a future where AI-driven technologies enhance our lives in profound and positive ways. | whatischatgpt | |

1,899,889 | The Magic of JavaScript Decorators: Enhancing Classes and Methods | JavaScript decorators are a powerful feature that allows developers to modify the behaviour of... | 0 | 2024-06-25T10:13:14 | https://dev.to/delia_code/the-magic-of-javascript-decorators-enhancing-classes-and-methods-4cec | webdev, javascript, programming, tutorial | JavaScript decorators are a powerful feature that allows developers to modify the behaviour of classes and their members. Decorators provide a clean and readable way to add annotations or meta-programming syntax for class declarations and members. This article delves into the magic of JavaScript decorators, explaining how they work and how they can be used to enhance your classes and methods.
## What are JavaScript Decorators?
Decorators are a stage 2 proposal for JavaScript, which means they are not yet a part of the ECMAScript standard but are widely used in modern JavaScript frameworks like Angular and libraries like TypeScript. A decorator is a special kind of declaration that can be attached to a class, method, accessor, property, or parameter. Decorators can modify the behavior of the decorated element in a declarative manner.
### Basic Syntax
Decorators are denoted by the `@` symbol followed by an expression. They can be applied to classes, methods, accessors, properties, and parameters.
```javascript
function MyDecorator(target) {
// Do something with the target
}
@MyDecorator
class MyClass {
// ...
}
```
### Applying Decorators
Decorators can be applied to various elements of a class:
1. **Class Decorators**: Applied to the entire class.
2. **Method Decorators**: Applied to a method.
3. **Accessor Decorators**: Applied to getters and setters.
4. **Property Decorators**: Applied to a class property.
5. **Parameter Decorators**: Applied to a method parameter.
### Example of a Class Decorator
A class decorator is a function that takes a single parameter: the constructor of the class.
```javascript
function sealed(constructor) {
Object.seal(constructor);
Object.seal(constructor.prototype);
}
@sealed
class MyClass {
constructor(name) {
this.name = name;
}
}
```
In this example, the `sealed` decorator seals the constructor and its prototype, preventing any extensions to the class.
## Enhancing Methods with Decorators
Method decorators are used to modify the behavior of methods. They take three parameters: the target (either the constructor function for a static method or the prototype of the class for an instance method), the name of the method, and the property descriptor.
### Example of a Method Decorator
```javascript
function log(target, key, descriptor) {
const originalMethod = descriptor.value;
descriptor.value = function (...args) {
console.log(`Calling ${key} with arguments`, args);
const result = originalMethod.apply(this, args);
console.log(`Result of ${key}:`, result);
return result;
};
return descriptor;
}
class Calculator {
@log
add(a, b) {
return a + b;
}
}
const calculator = new Calculator();
calculator.add(2, 3); // Console: Calling add with arguments [2, 3], Result of add: 5
```
In this example, the `log` decorator wraps the original `add` method, logging the method name and arguments before calling the method, and logging the result afterward.
## Property Decorators
Property decorators are used to observe and modify the behavior of properties. They receive two parameters: the target (either the constructor function for a static member or the prototype of the class for an instance member) and the name of the property.
### Example of a Property Decorator
```javascript
function readonly(target, key, descriptor) {
descriptor.writable = false;
return descriptor;
}
class Person {
@readonly
name = 'John Doe';
}
const person = new Person();
person.name = 'Jane Doe'; // TypeError: Cannot assign to read-only property 'name'
```
In this example, the `readonly` decorator sets the `writable` property of the descriptor to `false`, making the `name` property read-only.
## Accessor Decorators
Accessor decorators are applied to properties and methods to control access to class members.
### Example of an Accessor Decorator
```javascript
function configurable(value) {
return function (target, key, descriptor) {
descriptor.configurable = value;
return descriptor;
};
}
class Car {
constructor(make, model) {
this.make = make;
this.model = model;
}
@configurable(false)
get description() {
return `${this.make} ${this.model}`;
}
}
const myCar = new Car('Toyota', 'Camry');
console.log(myCar.description); // "Toyota Camry"
```
In this example, the `configurable` decorator modifies the `configurable` attribute of the `description` property.
## Parameter Decorators
Parameter decorators are used to annotate or modify function parameters.
### Example of a Parameter Decorator
```javascript
function required(target, key, index) {
console.log(`Parameter at position ${index} in ${key} is required`);
}
class User {
greet(@required name) {
return `Hello, ${name}`;
}
}
const user = new User();
user.greet('Alice'); // Console: Parameter at position 0 in greet is required
```
In this example, the `required` decorator logs a message indicating that a parameter is required.
## Best Practices and Use Cases
1. **Code Reusability**: Decorators allow you to define reusable functionalities that can be easily applied to different classes or methods.
2. **Separation of Concerns**: Decorators help separate core logic from auxiliary functionalities like logging, validation, or authorization.
3. **Readability**: Decorators make the code more readable by providing a clear and concise way to apply behaviors.
### Common Use Cases
- **Logging**: Automatically log method calls and results.
- **Validation**: Validate method parameters or class properties.
- **Authorization**: Check user permissions before executing a method.
- **Caching**: Implement caching mechanisms for expensive operations.
- **Error Handling**: Automatically catch and handle errors in methods.
## Advanced Usage
### Composing Multiple Decorators
You can apply multiple decorators to a single element. They are evaluated in reverse order of their appearance.
```javascript
function first(target, key, descriptor) {
console.log('first');
return descriptor;
}
function second(target, key, descriptor) {
console.log('second');
return descriptor;
}
class Example {
@first
@second
method() {
console.log('method');
}
}
const example = new Example();
example.method(); // Console: second, first, method
```
### Using Decorators with Metadata
Decorators can also interact with metadata, providing a way to store and retrieve metadata about classes and methods.
```javascript
import 'reflect-metadata';
function metadata(key, value) {
return function (target, propertyKey) {
Reflect.defineMetadata(key, value, target, propertyKey);
};
}
class Example {
@metadata('role', 'admin')
method() {}
}
const role = Reflect.getMetadata('role', Example.prototype, 'method');
console.log(role); // "admin"
```
In this example, the `metadata` decorator adds metadata to the `method` function.
JavaScript decorators are a powerful tool for enhancing the behavior of classes and methods in a clean, readable, and reusable way. While still a proposal, decorators are widely used in modern JavaScript development, especially in frameworks like Angular and libraries like TypeScript. By mastering decorators, you can write more maintainable and scalable code. Remember to use decorators to improve code reusability, separation of concerns, and readability.
To learn more about decorators, refer to the [TC39 Decorators Proposal](https://github.com/tc39/proposal-decorators) and explore frameworks and libraries that implement this feature.

Angular signals provide an excellent mechanism for managing state, so I decided to implement the event bus pattern using Angular signals.
In my recent project, I am developing a dashboard where the widgets need to communicate with each other while remaining standalone. Each widget has its own state and API, making the event bus pattern a perfect fit for this scenario.
## EventBus
## Example
Publish banana to the EventBus
```
import { SignalBusService } from 'ng-signal-bus'
@Component({
selector: 'app-widget-add-grocery-items',
standalone: true,
})
export class WidgetAddGroceryItemsComponent {
signalBus = inject(SignalBusService)
constructor() {
this.publish('fruit:banana', 'Banana')
}
publish(key:string, data: any) {
this.signalBus.publish(key, data)
}
}
```
Subscribe to the eventBus and listen for all fruits with the `fruit:*` selector.
```
import { SignalBusService } from 'ng-signal-bus'
@Component({
selector: 'app-widget-fruit-list',
standalone: true,
})
export class WidgetFruitListComponent {
signalBus = inject(SignalBusService)
ngOnInit() {
this.signalBus.subscribe('fruit:*', (metaData) => {
// Outputs { data: 'Banana', timestamp: 1434342 }
console.log(metaData);
});
}
}
```
### metaData
Inside the subscribe callback the service returns a metaData object
```
export interface MetaData {
data: any;
timestamp: number;
}
```
In this example, we use a simple string as the payload, but you can also provide an object.
```
this.publish('fruit:banana', { name: 'Banana', amount: 4 } )
// output
{
data: { name: 'Banana', amount: 4 }
timestamp: 232322
}
```
## Demo
Full demo see [Stackblitz](https://stackblitz.com/edit/stackblitz-starters-ahglvf?file=src%2Fapp%2Fwidget-add-grocery-items%2Fwidget-add-grocery-items.component.html)
{% embed https://stackblitz.com/edit/stackblitz-starters-ahglvf?embed=1&file=src%2Fmain.ts %}
## Package
{% embed https://www.npmjs.com/package/ng-signal-bus %}
I have packaged the SignalBusService into an [NPM package](https://www.npmjs.com/package/ng-signal-bus), so you can easily use it in your project.
### Angular Signal
Under the hood it's using a signal to store and mutate data, the effect() calls the callback function to update subscribers.
Note: Only tested with Angular v18.

title: How to improve your Git commits with Commitizen
published: true

tags: git
canonical_url: https://neurowinter.com/git/2023/04/04/commitizen/

## Summary
Commitizen is a CLI tool that can be used to help communicate changes made in commits to both future you and other team members. The goal of this is to stop all those commit messages of “WIP” or “fixing stuff”.
There have been countless times when I know that a change in file X has causes this issue, but I have no way of knowing which commit did it. So I end up spending far too long looking through all the commits to find the right one.
Commitizen also aids a team in using [Semantic Versioning](https://semver.org/)as it helps you automatically up version numbers based on changes.
## Why
Why do we need yet another tool in our workflow, don’t we have enough?
Git commit messages are a very under-utilized tool in the programming workflow, a lot of us will make a tonne of changes to all sorts of files, and then commit them all under a single commit. This leads to very difficult rollbacks, as you need to roll back all of them. This practice also leads to unhelpful commit messages, as the larger a change is, the harder it is to succinctly describe what is going on. Leading to terrible messages like “WIP”. Not only do these commit messages provide 0 value and seem useless, they are also a hindrance. When it comes to Code Review, you need to be able to explain your changes succinctly to the reviewer, other than sitting down and having a chat with the reviewer this can be difficult. This is where good commit messages come in and Conventional Commits.
Conventional commits is a super easy specification to follow, it is basically a set of rules that help you to create meaningful commit messages. You can read more about it, and the full specification,[here](https://www.conventionalcommits.org/en/v1.0.0/#summary).
## How
Now while the above are all reasons that you should write better commits, we often say that we will follow these practices, but end up falling back into our old ways. We need a way to ensure that we follow what we have defined as best practice. Here is where Commitizen comes in!
One way to change process is to make it as easy as possible. Commitizen is a super easy to use tool that will help you right good commit messages. E.g.:
```
❯ neurowinter.github.io (fix-working-in-aws-blog) ✘ cz c
? Select the type of change you are committing refactor: A code change that neither fixes a bug nor adds a feature
? What is the scope of this change? (class or file name): (press [enter] to skip)
_posts/2023-01-09-removing-aws-blog.md
? Write a short and imperative summary of the code changes: (lower case and no period)
change wording for paragraph
? Provide additional contextual information about the code changes: (press [enter] to skip)
? Is this a BREAKING CHANGE? Correlates with MAJOR in SemVer No
? Footer. Information about Breaking Changes and reference issues that this commit closes: (press [enter] to skip)
```
Once you have added the code you want to commit (remember you should keep your commits as small as possible) you can then run `cz c` to create a nice git log entry to allow your fellow contributors to better understand your changes. Having to write something about what has changed forces you to keep your commits small, as when you have committed a lot of changes, you will struggle to describe the exact changes. Continue this process for some time, and it will help you not only keep your git log looking nice, but it will also help you keep your commits small.
Now that you have made some commits, you can view your git log in all of its glory:
```

This article explores the various ways Postman scripts can optimize your API testing regimen, supplying you with code examples to improve efficiency and effectiveness.
## Why Use Postman Scripts?
Through JavaScript, Postman scripts provide automation capabilities and dynamic options to applications, significantly enhancing functionality. Here’s how these scripts can augment your development and testing process:
### Task Automation
Automating tasks that are needlessly repetitive frees up valuable developer time and increases efficiency. For example, instead of manually sending API requests with numerous slight parameter variations, Postman scripts handle such tasks seamlessly, automatically tuning request parameters, headers, or URLs to fit specific criteria.
### Crafting Dynamic Requests
Static requests suffice for basic operations, but the dynamic nature of most applications demands more flexibility. Postman scripts equip you to dynamically assemble requests based on real-time data or randomized input, ensuring a more robust testing scenario.
### Sophisticated Data Validation
Beyond simply checking API response statuses, Postman scripts delve into response content. They are capable of parsing intricate JSON structures, extracting key data, and validating it against predefined requirements to ensure not only the API's functionality but also its reliability and accuracy.
### Logic-Driven Workflows
Managing complex testing workflows becomes straightforward with Postman scripts. Depending on the outcome of an API call—be it a success, error, or data-dependent condition—the scripts can route the process flow, deciding to execute further actions or cease additional tests.
### Enhanced Integration and Reusability
Postman’s scripts integrate seamlessly within the broader ecosystem of its features, such as Collections and Environments. Scripts can also be repurposed across multiple requests, streamlining the development process by reducing redundancy and encouraging modular, reusable code components.
## Practical Postman Script Implementations
Below are sample scripts demonstrating how developers might enhance their API interactions using Postman:
### Dynamic Parameter Adjustment
```
// Automatically append current timestamp to the request body
pm.request.body.put("timestamp", new Date().getTime());
// Construct request URL using an environment variable
`${pm.environment.get("baseURL")}/users/${pm.variables.get("userId")}`;
```
### Crafting Requests on the Fly
```
// Iterate over user IDs to send individual GET requests
pm.collectionVariables.forEach(id => {
pm.sendRequest(`${pm.environment.get("baseURL")}/users/${id}`, { method: "GET" });
});
// Create a POST request with randomly generated data
pm.request.body.put("name", pm.fake.name());
pm.request.body.put("email", pm.fake.email());
```
### Validating API Responses
```
// Verify successful response status
pm.test("Status code is 200", () => {
pm.response.to.have.status(200);
});
// Check for specific data within the JSON response
const data = pm.response.json();
pm.expect(data.id).to.equal(123);
```
### Conditional Responses and Workflow Navigation
```
// Skip tests on encountering a 404 error
pm.test("Check for page not found", () => {
if (pm.response.to.have.status(404)) {
pm.test.skip("This API endpoint is missing, skipping further tests");
}
});
```
## Implement Scripts with Ease Using [Apidog](https://www.apidog.com/?utm_source=&utm_medium=blogger&utm_campaign=test1)
Implementing scripts is easier than before! Introducing Apidog, a comprehensive API development platform that equips users with complete tools for the entire API lifecycle.
## Importing APIs to Apidog for Modificiation
Take your first step to perfecting your API by importing them onto Apidog. Apidog supports various API file types, including [OpenAPI (or Swagger)](http://apidog.com/blog/free-openapi-documentation-tool/), [Postman](http://apidog.com/blog/shifting-from-postman-to-apidog/), and [Insomnia](http://apidog.com/blog/insomnia-api/).
First, open the Settings section in your project, and locate the `Import Data` button found under Data Management. If you cannot find the file type you wish to import, do not worry! Simply drag and drop the file to the bottom portion of the screen.
## Adding Custom Scripts in Apidog
Once you have finished importing your API or creating a new project on Apidog, you can proceed with adding custom scripts.
Under the Edit section of your API, locate the `Pre Processors` heading. You should find a bar that is labeled `Custom Script`. This is where you can implement custom scripts for your API requests. If you are struggling with figuring out what to write, you can also select the Code Snippet options found on the right of the codespace.
## Conclusion
Leveraging Postman scripts not only refines API testing but also brings strategic benefits, fostering a more controlled and insightful development environment. With tools like Apidog simplifying the integration, development, and documentation processes, adapting Postman scripts becomes a straightforward and rewarding endeavor. Embrace these modern tools and scripting advantages to elevate your API projects. | sattyam |
1,899,883 | useReducer hook | We will see how to implement this using the useState hook. The ReducerTutorial React component... | 0 | 2024-06-25T10:07:02 | https://dev.to/geetika_bajpai_a654bfd1e0/usereducer-hook-550i |
We will see how to implement this using the useState hook.
The ReducerTutorial React component demonstrates the use of the useState hook to manage two state variables: count (initialized to 0) and showText (initialized to true). The component renders a count value, a button, and conditionally displays a paragraph of text based on the value of showText. When the button is clicked, the count is incremented by 1 and showText is toggled between true and false, controlling the visibility of the text.
## Understanding useReducer
useReducer is a React hook that is used for managing more complex state logic in a component, especially when the state depends on previous states or involves multiple state variables. It is an alternative to useState and is particularly useful when you have a complex state object or need to handle complex state transitions.
## Why Use useReducer Here
In the context of the ReducerTutorial component, useReducer could be used instead of useState for several reasons:
<u>Complex State Logic:</u> If the state transitions (how state changes in response to actions) are complex, useReducer provides a more structured approach.
<u>Multiple State Variables: </u>Managing multiple related state variables can become cumbersome with useState. useReducer allows grouping related state variables together.
<u>Predictable State Updates:</u> useReducer ensures state updates are predictable and easier to trace, as all state changes are handled through a single function (the reducer).
## What is useReducer
useReducer is a hook that takes two arguments:
A reducer function: (state, action) => newState
An initial state
The reducer function contains the logic to determine the new state based on the current state and the action dispatched. useReducer returns an array with the current state and a dispatch function, which is used to dispatch actions that trigger state transitions.
## Code Explanation
The ReducerTutorial component demonstrates the use of the useReducer hook to manage complex state in React. It defines a reducer function to handle state transitions based on dispatched actions. The component maintains two state variables, count and showText, initialized to 0 and true, respectively. On clicking the button, it dispatches INCREMENT to increase the count and TOGGLE_TEXT to toggle the visibility of a text paragraph. The useReducer hook provides a structured approach to state management, making it suitable for handling multiple related state variables and complex state logic.
