electron-proxy-agent

A proxy `http.Agent` implementation for HTTP and HTTPS,

rewritten to work seamlessly with Electron API

This module provides an http.Agent implementation that uses the session.resolveProxy API of Electron to resolve which HTTP, HTTPS, or SOCKS proxy, or if a direct connection should be used to connect to the HTTP(S) endpoint.

It is designed to be be used with the built-in http and https modules

Installation

Install with npm:

$ npm install electron-proxy-agent --save

Examples

Single request

var url = require('url');
var http = require('http');
var ElectronProxyAgent = require('electron-proxy-agent');
var session = require('session').defaultSession;

// HTTP endpoint for the proxy to connect to
var endpoint = 'http://nodejs.org/api/';
console.log('attempting to GET %j', endpoint);
var opts = url.parse(endpoint);

// create an instance of the `ElectronProxyAgent` class with the default electron session
var agent = new ElectronProxyAgent(session);
opts.agent = agent;

http.get(opts, function (res) {
  console.log('"response" event!', res.headers);
  res.pipe(process.stdout);
});

Global agent

var http = require('http');
var https = require('http');
var ElectronProxyAgent = require('electron-proxy-agent');
var session = require('session').defaultSession;

// use ElectronProxyAgent as http and https globalAgents
http.globalAgent = https.globalAgent = new ElectronProxyAgent(session);

Notes

Passing no or invalid parameter to the constructor would result in trying to use default session.

new ElectronProxyAgent() // try to use default session

Could be used or mocked out of Electron by passing an object that implements resolveProxy

new ElectronProxyAgent({
  resolveProxy : function(url, callback) {
    callback("PROXY 127.0.0.1:8888; DIRECT"); // return a valid pac syntax
  }
})
