What is pac-resolver?

The pac-resolver package is a module for Node.js that allows you to parse and execute PAC (Proxy Auto-Configuration) files to determine the appropriate proxy for a given URL. PAC files are written in JavaScript and are used to specify whether web browsers should direct traffic through a proxy server or connect directly.

What are pac-resolver's main functionalities?

Executing PAC Scripts

This feature allows you to execute a PAC script to determine the proxy for a given URL. The code sample demonstrates how to create a simple PAC function that always returns 'DIRECT', meaning no proxy is used.

const pac = require('pac-resolver');
const FindProxyForURL = pac('function FindProxyForURL(url, host) { return 'DIRECT'; }');
FindProxyForURL('http://example.com').then(console.log); // 'DIRECT'

Asynchronous PAC Script Execution

This feature allows for asynchronous execution of PAC scripts using async/await syntax. The code sample demonstrates how to define a PAC function that specifies a proxy server and then asynchronously retrieves the proxy for a URL.

const pac = require('pac-resolver');
const FindProxyForURL = pac('function FindProxyForURL(url, host) { return 'PROXY proxy.example.com:8080'; }');
(async () => {
  const proxy = await FindProxyForURL('http://example.com');
  console.log(proxy); // 'PROXY proxy.example.com:8080'
})();
