HTTP2 Proxy Request

This library allows you to send requests using a proxy with the http2 protocol. If you don't need to use it with a proxy, check the node:http2 library.

Sample GET Request

const { request } = require('http2-proxy-request')

request({
    url: 'https://example.com/',
    proxy: {
        host: '<proxy-host>',
        port: '<proxy-port>',
        username: '<proxy-username>',
        password: '<proxy-password>'
    },
    headers: {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'
    },
    method: 'GET'
}).then(console.log).catch(console.error)

Sample POST Request

If body is of type json, you should add “Content-Type”: “application/json”.

const { request } = require('http2-proxy-request')

request({
    url: 'https://example.com/',
    proxy: {
        host: '<proxy-host>',
        port: '<proxy-port>',
        username: '<proxy-username>',
        password: '<proxy-password>'
    },
    headers: {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3',
        "Content-Type": "application/json"
    },
    method: 'POST',
    body: { a: 1 }
}).then(console.log).catch(console.error)

Sample Response

3 Variables are returned. headers, body and statusCode.

  headers: {
    ':status': 200,
    date: 'Sun, 19 May 2024 19:40:01 GMT',

      'content-type': 'application/json',
    },
    body: {},
    method: 'GET',
    url: '/',
    query: {},
    params: {},
    path: '/',
    httpVersion: '1.1'
  },
  statusCode: 200
}

Why Did I Create This Library?

Due to the waf rules added to some sites protected with Cloudflare, we are recognized as bots when we send htttp/1.1 requests. Currently, most libraries don't support sending http2 requests using a proxy. If they did, it was very complicated. I wanted to simplify this.

Thank You

After searching for a long time I saw this answer and made this code into a library, thanks.
