The pac-proxy-agent npm package is a module for Node.js that allows HTTP/HTTPS requests to respect PAC (Proxy Auto-Configuration) files. PAC files are used to determine the appropriate proxy server when making network requests. This package is useful for applications that need to handle network requests in environments with complex proxy configurations.

What are pac-proxy-agent's main functionalities?

HTTP/HTTPS request handling with PAC file

This code sample demonstrates how to use the pac-proxy-agent to make an HTTP request that respects a PAC file located at a specified URL. The agent is then used with the HTTP request options to ensure the request follows the proxy rules defined in the PAC file.

const PacProxyAgent = require('pac-proxy-agent');
const url = require('url');

const agent = new PacProxyAgent('http://example.com/proxy.pac');
const opts = url.parse('http://nodejs.org/api/');
opts.agent = agent;

require('http').get(opts, (res) => {
  console.log('Got response: ' + res.statusCode);
}).on('error', (e) => {
  console.error('Got error: ' + e.message);
});

A PAC file proxy `http.Agent` implementation for HTTP and HTTPS

This module provides an http.Agent implementation that retreives the specified PAC proxy file and uses it to resolve which HTTP, HTTPS, or SOCKS proxy, or if a direct connection should be used to connect to the HTTP endpoint.

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

Installation

Install with npm:

$ npm install pac-proxy-agent

Example

var url = require('url');
var http = require('http');
var PacProxyAgent = require('pac-proxy-agent');

// URI to a PAC proxy file to use (the "pac+" prefix is stripped)
var proxy = 'pac+https://cloudup.com/ceGH2yZ0Bjp+';
console.log('using PAC proxy proxy file at %j', proxy);

// 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 `PacProxyAgent` class with the PAC file location
var agent = new PacProxyAgent(proxy);
opts.agent = agent;

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