Minimal HTTP and Websocket proxy server in Node

index.js

const http = require('http');
const httpProxy = require('http-proxy');

const proxy = new httpProxy.createProxyServer({
  target: {
    host: 'notebook',
    port: 8888
  }
});
var proxyServer = http.createServer(function (req, res) {
  proxy.web(req, res);
});

proxyServer.on('upgrade', function (req, socket, head) {
  proxy.ws(req, socket, head);
});

proxyServer.listen(8888);
