Using Adonis.js with Other Libraries like Helmet.js

Adonis.js is a popular Node.js framework that allows developers to build robust and scalable web applications. While Adonis.js provides a lot of built-in features, there are cases where you might want to use other libraries to enhance the functionality of your application. In this article, we will explore how to use Adonis.js with other libraries like Helmet.js.

What is Helmet.js?

Helmets.js is a popular Node.js library that helps you secure your web application by setting various HTTP headers. It provides a simple way to set headers like Content Security Policy (CSP), Cross-Origin Resource Sharing (CORS), and more.

Why Use Helmet.js with Adonis.js?

While Adonis.js provides some built-in security features, using Helmet.js can provide additional security benefits. Helmet.js allows you to set specific HTTP headers that can help prevent common web attacks like cross-site scripting (XSS) and cross-site request forgery (CSRF).

Installing Helmet.js with Adonis.js

To use Helmet.js with Adonis.js, you need to install the `@adonisjs/helmet` package. You can do this by running the following command in your terminal:

npm install @adonisjs/helmet

Configuring Helmet.js with Adonis.js

After installing the `@adonisjs/helmet` package, you need to configure it in your Adonis.js application. You can do this by creating a new file called `helmet.js` in the `config` directory of your project.

// config/helmet.js
import { HelmetConfig } from '@adonisjs/helmet'

export default () => {
  return {
    // Enable or disable Helmet.js
    enabled: true,

    // Set the Content Security Policy (CSP) header
    contentSecurityPolicy: {
      directives: {
        defaultSrc: ["'self'"],
        scriptSrc: ["'self'", 'https://cdn.jsdelivr.net'],
        styleSrc: ["'self'", 'https://fonts.googleapis.com'],
        fontSrc: ["'self'", 'https://fonts.gstatic.com'],
      },
    },

    // Set the Cross-Origin Resource Sharing (CORS) header
    crossOriginResourcePolicy: {
      policy: 'same-origin',
    },
  }
}

Using Helmet.js in Adonis.js Routes

After configuring Helmet.js, you can use it in your Adonis.js routes. You can do this by importing the `Helmet` middleware and adding it to your route.

// routes.js
import Route from '@ioc:Adonis/Core/Route'
import Helmet from '@ioc:Adonisjs/Helmet'

Route.get('/', async ({ view }) => {
  return view.render('welcome')
}).middleware([Helmet.middleware()])
