socks-proxy-agent

What is socks-proxy-agent?

The socks-proxy-agent package is a SOCKS proxy http.Agent implementation for HTTP and HTTPS. This package allows you to route HTTP and HTTPS requests through a SOCKS proxy server. It is useful for bypassing network restrictions or connecting to servers anonymously.

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

HTTP/HTTPS request via SOCKS proxy

This code sample demonstrates how to send an HTTP or HTTPS request through a SOCKS proxy using the socks-proxy-agent package. The agent is created with the proxy server information and passed to the HTTP request options.

const SocksProxyAgent = require('socks-proxy-agent');
const agent = new SocksProxyAgent('socks://localhost:1080');
const https = require('https');

https.get('https://example.com', { agent }, (res) => {
  console.log(`Got response: ${res.statusCode}`);
  // consume response body
  res.resume();
}).on('error', (e) => {
  console.error(`Got error: ${e.message}`);
});

Other packages similar to socks-proxy-agent

http-proxy-agent

The http-proxy-agent package provides an http.Agent implementation that connects to a specified HTTP proxy server, and can be used for forwarding HTTP requests. Unlike socks-proxy-agent, it does not support SOCKS proxies, only HTTP.

https-proxy-agent

Similar to http-proxy-agent, https-proxy-agent provides an http.Agent implementation for HTTPS requests that connects to an HTTPS proxy server. It is specifically designed for HTTPS connections and does not support SOCKS proxies.

proxy-agent

The proxy-agent package is a more general solution that supports multiple proxy protocols including HTTP, HTTPS, SOCKS, and PAC files. It can be used as a drop-in replacement for the standard http.Agent and automatically selects the appropriate agent based on the proxy's protocol. This makes it more versatile than socks-proxy-agent, which is specialized for SOCKS proxies only.

socks-proxy-agent

A SOCKS proxy http.Agent implementation for HTTP and HTTPS

This module provides an http.Agent implementation that connects to a specified SOCKS proxy server, and can be used with the built-in http or https modules.

It can also be used in conjunction with the ws module to establish a WebSocket connection over a SOCKS proxy. See the "Examples" section below.

Installation

Install with npm:

$ npm install socks-proxy-agent

Examples

http module example

var url = require('url');
var http = require('http');
var SocksProxyAgent = require('socks-proxy-agent');

// SOCKS proxy to connect to
var proxy = process.env.socks_proxy || 'socks://127.0.0.1:9050';
console.log('using proxy server %j', proxy);

// HTTP endpoint for the proxy to connect to
var endpoint = process.argv[2] || 'http://nodejs.org/api/';
console.log('attempting to GET %j', endpoint);
var opts = url.parse(endpoint);

// create an instance of the `SocksProxyAgent` class with the proxy server information
var agent = new SocksProxyAgent(proxy);
opts.agent = agent;

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

https module example

var url = require('url');
var https = require('https');
var SocksProxyAgent = require('socks-proxy-agent');

// SOCKS proxy to connect to
var proxy = process.env.socks_proxy || 'socks://127.0.0.1:9050';
console.log('using proxy server %j', proxy);

// HTTP endpoint for the proxy to connect to
var endpoint = process.argv[2] || 'https://encrypted.google.com/';
console.log('attempting to GET %j', endpoint);
var opts = url.parse(endpoint);

// create an instance of the `SocksProxyAgent` class with the proxy server information
// NOTE: the `true` second argument! Means to use TLS encryption on the socket
var agent = new SocksProxyAgent(proxy, true);
opts.agent = agent;

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

ws WebSocket connection example

var WebSocket = require('ws');
var SocksProxyAgent = require('socks-proxy-agent');

// SOCKS proxy to connect to
var proxy = process.env.socks_proxy || 'socks://127.0.0.1:9050';
console.log('using proxy server %j', proxy);

// WebSocket endpoint for the proxy to connect to
var endpoint = process.argv[2] || 'ws://echo.websocket.org';
console.log('attempting to connect to WebSocket %j', endpoint);

// create an instance of the `SocksProxyAgent` class with the proxy server information
var agent = new SocksProxyAgent(proxy);

// initiate the WebSocket connection
var socket = new WebSocket(endpoint, { agent: agent });

socket.on('open', function () {
  console.log('"open" event!');
  socket.send('hello world');
});

socket.on('message', function (data, flags) {
  console.log('"message" event! %j %j', data, flags);
  socket.close();
});
