Fixie works with both the standard http and https modules and with higher-level http clients, including the popular axios library.

Using Axios

const axios = require('axios');
const url = require('url');
const fixieUrl = url.parse(process.env.FIXIE_URL);
const fixieAuth = fixieUrl.auth.split(':');

axios.get('https://example.com', {
  proxy: {
    protocol: 'http',
    host: fixieUrl.hostname,
    port: fixieUrl.port,
    auth: {username: fixieAuth[0], password: fixieAuth[1]}
  }
}).then(response => {
  console.log(response.status);
});

Using fetch

const HttpsProxyAgent = require('https-proxy-agent');

const response = await fetch("https://example.com", {
  agent: new HttpProxyAgent({
    proxy: process.env.FIXIE_URL
  }),
});

Using http

For those using Fixie Socks,the socks npm package provides an agent that can be used by the Node’s http and https libraries, as well as by popular higher-level libraries like request.

const http = require('http');
const Socks = require('socks');

const fixieUrl = process.env.FIXIE_SOCKS_HOST;
const fixieValues = fixieUrl.split(new RegExp('[/(:\\/@)/]+'));

const socksAgent = new Socks.Agent({
    proxy: {
        ipaddress: fixieValues[2],
        port: fixieValues[3],
        type: 5,
        authentication: {
            username: fixieValues[0],
            password: fixieValues[1]
        }
    }},
    true, // true HTTPS server, false for HTTP server
    false // rejectUnauthorized option passed to tls.connect()
);

function resHandler(res) {
  let responseBody = '';
  res.on('data', (chunk) => {
    responseBody += chunk;
  });
  res.on('error', () => {
    process.exit(1);
  });
  res.on('end', () => {
    console.log(responseBody);
    socksAgent.encryptedSocket.end();
  });
}


http.get({ hostname: 'example.com', port: '443', agent: socksAgent}, resHandler);

Connecting to MySQL

MySql2 connects via a SOCKS connection provided as the stream property. Because Fixie Socks terminates idle connections after 60 seconds of inactivity, we suggest using connection pooling (this is a best practice regardless) or manual error handling. The example below uses connection pooling:

const SocksConnection = require('socksjs');
const mysql = require('mysql2');
const fixieUrl = process.env.FIXIE_SOCKS_HOST;
const fixieValues = fixieUrl.split(new RegExp('[/(:\\/@)/]+'));

const mysqlServer = {
  host: 'your-host.example.com',
  port: 3306
};

const dbUser = 'user';
const dbPassword = 'password';
const db = 'database';

const fixieConnection = new SocksConnection(mysqlServer, {
  user: fixieValues[0],
  pass: fixieValues[1],
  host: fixieValues[2],
  port: fixieValues[3],
});

const mysqlConnPool = mysql.createPool({
  user: dbUser,
  password: dbPassword,
  database: db,
  stream: fixieConnection
});

mysqlConnPool.getConnection(function gotConnection(err, connection) {

  if (err) throw err;

  queryVersion(connection);
});

function queryVersion(connection) {
  connection.query('SELECT version();', function (err, rows, fields) {

      if (err) throw err;

      console.log('MySQL/MariaDB version: ', rows);
      connection.release();
      process.exit();
  });
}

Connecting to Postgres or Amazon Redshift

As with mysql, you can pass a custom stream to the node-postgres library. This will work both for connections to Postgres databases as well as to Amazon Redshift:

const pg = require('pg');
const SocksConnection = require('socksjs');

const fixieUrl = process.env.FIXIE_SOCKS_HOST;
const fixieValues = fixieUrl.split(new RegExp('[/(:\\/@)/]+'));

const pgServer = {
  host: 'YOUR-HOST',
  port: 5432
};

const fixieConnection = new SocksConnection(pgServer, {
  user: fixieValues[0],
  pass: fixieValues[1],
  host: fixieValues[2],
  port: fixieValues[3],
});

const connectionConfig = {
  user: 'YOUR-DB-USERNAME',
  password: 'YOUR-DB-PASSWORD',
  database: 'YOUR-DATABASE',
  stream: fixieConnection,
  ssl: true // Optional, depending on db config
};

var client = new pg.Client(connectionConfig);

client.connect(function (err) {
  if (err) throw err;
  client.query('SELECT 1+1 as test1', function (err, result) {
    if (err) throw err;
    console.log(result.rows[0]);
    client.end(function (err) {
      if (err) throw err;
    });
  });
});

Connecting to MongoDB

const mongoose = require('mongoose');
const fixieData = process.env.FIXIE_SOCKS_HOST.split(new RegExp('[/(:\\/@/]+'));

mongoose.connect(process.env.DB_CONNECTION,
    {
      proxyUsername: fixieData[0],
      proxyPassword: fixieData[1],
      proxyHost: fixieData[2],
      proxyPort: fixieData[3]
     },
    (error) => {
      if(error){
        console.log(error)
      }
      console.log('Connected to database')}
)

Establishing an SSH connection

The SSH2 library can be used to establish an SSH connection and execute commands over Fixie Socks.

var socks = require('socksv5'),
    SSHClient = require('ssh2').Client;

const fixieUrl = process.env.FIXIE_SOCKS_HOST;
const fixieValues = fixieUrl.split(new RegExp('[/(:\\/@)/]+'));

socks.connect({
  host: 'ssh.example.org',
  port: 22,
  proxyHost: fixieValues[2],
  proxyPort: fixieValues[3],
  auths: [socks.auth.UserPassword(fixieValues[0], fixieValues[1])]
}, function(socket) {
  var conn = new SSHClient();
  conn.on('ready', function() {
    conn.exec('uptime', function(err, stream) {
      if (err) throw err;
      stream.on('close', function(code, signal) {
      conn.end();
      }).on('data', function(data) {
        console.log('STDOUT: ' + data);
      }).stderr.on('data', function(data) {
        console.log('STDERR: ' + data);
      });
    });
  }).connect({
    sock: socket,
    username: 'ssh-user',
    privateKey: require('fs').readFileSync('/here/is/my/key')
  });
});
