AdonisJS comes with a range of features that make it easier to build web applications. Some of these features include built-in authentication, database ORM, web sockets, task scheduling, and more.

What programming languages are used in AdonisJS?

AdonisJS is built on top of Node.js, which is a JavaScript runtime. This means that you will be writing your server-side code in JavaScript. However, AdonisJS also comes with a range of features that allow you to write your front-end code in other languages like HTML, CSS, and more.

What is the database ORM used in AdonisJS?

AdonisJS comes with its own database ORM called Lucid. It provides a simple and intuitive way to interact with your database and perform common operations like creating, updating, and deleting records.

What is the role of AdonisJS middleware?

Middleware in AdonisJS is used to perform actions on HTTP requests and responses. This can include things like authentication, logging, and more. Middleware functions are executed in a pipeline, allowing you to easily add and remove functionality as needed.

What is the role of AdonisJS service providers?

Service providers in AdonisJS are used to register and configure application services. This can include things like database connections, email services, and more. Service providers are executed during the application bootstrap process, allowing you to easily add and remove services as needed.

What is the role of AdonisJS controllers?

Controllers in AdonisJS are used to handle incoming HTTP requests and return responses. They typically contain methods that correspond to different HTTP verbs like GET, POST, and more. Controllers can also interact with models to perform database operations.

What is the role of AdonisJS views?

Views in AdonisJS are used to render HTML templates that are returned in response to HTTP requests. They can be used to dynamically generate content based on data from the database or other sources. AdonisJS uses the Edge template engine by default, but you can also use other engines like Handlebars or EJS.

What is the role of AdonisJS routes?

Routes in AdonisJS are used to define the mapping between HTTP requests and controller methods. They typically specify a URL pattern, an HTTP verb, and a controller method to be executed when a request matches the pattern. Routes can also include middleware functions to be executed before or after the controller method.

How do I install AdonisJS?

You can install AdonisJS using the npm package manager. Simply run the command 'npm i -g @adonisjs/cli' to install the AdonisJS CLI globally. You can then use the CLI to create new AdonisJS applications and manage existing ones.
