proxy-agent

Maps proxy protocols to http.Agent implementations

This module provides an http.Agent implementation which automatically uses
proxy servers based off of the various proxy-related environment variables
(HTTP_PROXY, HTTPS_PROXY and NO_PROXY among others).

Which proxy is used for each HTTP request is determined by the
proxy-from-env module, so
check its documentation for instructions on configuring your environment variables.

An LRU cache is used so that http.Agent instances are transparently re-used for
subsequent HTTP requests to the same proxy server.

The currently implemented protocol mappings are listed in the table below:

Example

 import * as https from 'https';
import { ProxyAgent } from 'proxy-agent';

// The correct proxy `Agent` implementation to use will be determined
// via the `http_proxy` / `https_proxy` / `no_proxy` / etc. env vars
const agent = new ProxyAgent();

// The rest works just like any other normal HTTP request
https.get('https://jsonip.com', { agent }, (res) => {
  console.log(res.statusCode, res.headers);
  res.pipe(process.stdout);
});

API

new ProxyAgent(options?: ProxyAgentOptions)

Creates an http.Agent instance which relies on the various proxy-related
environment variables. An LRU cache is used, so the same http.Agent instance
will be returned if identical args are passed in.
