bent

What is bent?

The 'bent' npm package is a minimalistic and efficient HTTP client for Node.js. It is designed to be simple and easy to use, providing a straightforward API for making HTTP requests. It supports promises and async/await syntax, making it a modern choice for handling HTTP requests in Node.js applications.

What are bent's main functionalities?

Making GET Requests

This feature allows you to make GET requests and automatically parse the response as JSON. The 'bent' function is configured with 'json' to handle JSON responses.

const bent = require('bent');
const getJSON = bent('json');
(async () => {
  const response = await getJSON('https://api.example.com/data');
  console.log(response);
})();

Making POST Requests

This feature allows you to make POST requests with a JSON payload. The 'bent' function is configured with 'POST' and 'json' to handle JSON responses and ensure a 200 status code.

const bent = require('bent');
const post = bent('POST', 'json', 200);
(async () => {
  const response = await post('https://api.example.com/data', { key: 'value' });
  console.log(response);
})();

Handling Different Response Types

This feature allows you to handle different response types, such as buffers for binary data. The 'bent' function is configured with 'buffer' to handle binary responses.

const bent = require('bent');
const getBuffer = bent('buffer');
(async () => {
  const response = await getBuffer('https://example.com/image.png');
  console.log(response);
})();

Custom Headers

This feature allows you to set custom headers for your HTTP requests. The 'bent' function is configured with 'GET', 'json', and a headers object to include an authorization token.

const bent = require('bent');
const getWithHeaders = bent('GET', 'json', { 'Authorization': 'Bearer token' });
(async () => {
  const response = await getWithHeaders('https://api.example.com/data');
  console.log(response);
})();

Functional HTTP client for Node.js w/ async/await.

Usage

const bent = require('bent')

const getJSON = bent('json')
const getBuffer = bent('buffer')

let obj = await getJSON('http://site.com/json.api')
let buffer = await getBuffer('http//site.com/image.png')

As you can see, bent is a function that returns an async function.

Bent takes options which constrain what is accepted by the client. Any response that falls outside the constraints will generate an error.

If you don't set a response encoding ('json', 'string' or 'buffer') then the response stream will be returned after the statusCode check.

const bent = require('bent')

const getStream = bent('http://site.com')

let stream = await getStream('/json.api')

The following options are available.

• HTTP Method: 'GET', 'PUT', and any ALLCAPS string will be used to set the HTTP method. Defaults to 'GET'
• Response Encoding: Available options are 'string', 'buffer', and 'json'. If no encoding is set, which is the default, the response object/stream will be returned instead of a decoded response.
• Status Codes: Any number will be considered an acceptable status code. If none are provided 200 will be the only acceptable status code, but if status codes are provided 200 must be added explicitely.
• Headers: An object can be passed to set request headers.
• Base URL: Any string that begins with 'https:' or 'http:' is consider the Base URL. Subsequent queries need only pass the remaining URL string.

The returned async function is used for subsequent requests.

async request(url[, body=null])

• url: Fully qualified URL to the remote resource, or in the case that a base URL is passed the remaining URL string.
• body: Request body. Can be stream, buffer or JSON object.

const bent = require('bent')

const put = bent('PUT', 201)
await put('http://site.com/upload', Buffer.from('test'))
