Adonis - JavaScript

AdonisJS is a web framework for Node.js. It is highly performant and has a clean and simple API. AdonisJS is built on top of the well-known Express.js framework, but adds a more structured approach to building web applications.

Features

AdonisJS comes with an impressive set of features out of the box, making it a great choice for building complex applications. Some of the key features include:

• Route management
• Authentication
• Database ORM
• Middleware support
• Error handling
• Service providers

Getting Started

To get started with AdonisJS, you'll need to install it first. You can do this using npm:

npm install -g @adonisjs/cli

Once you've installed AdonisJS, you can create a new project using the following command:

adonis new myapp

This will create a new AdonisJS project called myapp. You can then run the project using the following command:

cd myapp
adonis serve --dev

This will start the AdonisJS server in development mode.

Routes

Routes are a critical part of any web application, and AdonisJS makes it easy to manage them. You can define routes using the routes/web.js file. For example:

const Route = use('Route')

Route.get('/', () => {
  return 'Hello world'
})

This code defines a route that responds with "Hello world" when the root URL is visited.

Middleware

AdonisJS also supports middleware, which can be used to modify incoming requests or outgoing responses. Middleware can be defined using the app/Http/Kernel.js file. For example:

const globalMiddleware = [
  'Adonis/Middleware/BodyParser'
]

const namedMiddleware = {
  auth: 'App/Middleware/Auth'
}

...

Route.get('/', () => {
  ...
}).middleware(['auth'])

This code defines a global middleware that parses the request body, as well as a named middleware called auth. The auth middleware is then applied to the route using the middleware method.

Conclusion

AdonisJS is a powerful web framework that makes it easy to build complex web applications. With its impressive set of features and easy-to-use API, it's a great choice for any JavaScript developer.
