Adonis Hook - Javascript

Adonis Hook is a lightweight NodeJS library that provides an easy way to intercept, modify and finally execute HTTP requests and responses within your application. With Adonis Hook, you can easily monitor and control how your applications interact with external APIs and services.

Features

• Intercept and modify HTTP requests and responses
• Easy integration with AdonisJS framework
• Fine-grained control over the request and response objects
• Lightweight and easy to use

Installation

You can install Adonis Hook using npm:

npm install adonis-hook

Usage

To use Adonis Hook in your application, you first need to create a hook class that extends the base Hook class provided by Adonis Hook:

const { Hook } = require('adonis-hook')

class MyHook extends Hook {
  async onRequest (request) {
    // ...
  }

  async onResponse (response) {
    // ...
  }
}

In the onRequest and onResponse methods, you can manipulate the request and response objects respectively, before they are sent or returned to the client.

Once you have created your hook class, you can register it with Adonis Hook:

const { AdonisHook } = require('adonis-hook')

AdonisHook.addHook(MyHook)

This will register your hook class with Adonis Hook. From now on, any HTTP requests made by your application will be intercepted by your hook class.

Example

Here is an example that demonstrates how you can use Adonis Hook to modify the response of an HTTP request:

const { Hook } = require('adonis-hook')
const axios = require('axios')

class ModifyResponseHook extends Hook {
  async onRequest (request) {
    console.log(`Requesting ${request.method} ${request.url}`)
  }

  async onResponse (response) {
    console.log(`Response received with status ${response.status}:`)
    console.log(response.data)

    // Modify the response data
    response.data = 'This is a modified response'
  }
}

AdonisHook.addHook(ModifyResponseHook)

// Send an HTTP request to a test API
axios.get('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => console.log(response.data))
  .catch(error => console.error(error))

In this example, we create a hook class called ModifyResponseHook that logs information about the HTTP request and response, and modifies the response data that is returned to the client. We register the hook class with Adonis Hook using AdonisHook.addHook, and then send an HTTP request using the axios library. When the response is received, our hook class is invoked, modifies the response data, and logs the modified data to the console.

Conclusion

Adonis Hook provides a powerful and lightweight way for NodeJS developers to intercept, modify and finally execute HTTP requests and responses within their applications. With Adonis Hook, you have fine-grained control over how your applications interact with external APIs and services, allowing you to build more robust and scalable applications.
