A very basic reverse proxy server

reverse-proxy-server.js

var http = require('http'),
    httpProxy = require('http-proxy'),
    proxy = httpProxy.createProxyServer({});
var url = require('url');

http.createServer(function (req, res) {
    var pathname = url.parse(req.url).pathname;
    console.log('pathname', pathname);
    var conversationsPath = '/api/conversations';
    var discoverPath = '/api/discover';
    if (pathname.substring(0, conversationsPath.length) == conversationsPath) {
        console.log('  Conversations    >>>> http://localhost:9999');
        proxy.web(req, res, {
            target: 'http://localhost:9999'
        });
    }
    else if (pathname.substring(0, discoverPath.length) == discoverPath) {
        console.log(' Discovery     >>>> http://localhost:3330');
        proxy.web(req, res, {
            target: 'http://localhost:3330'
        });
    }
    else {
        console.log('   Norman   >>>> http://localhost:9000');
        proxy.web(req, res, {
            target: 'http://localhost:9000'
        });
    }
}).listen(8000);
