Simple reverse proxy. forwards /api to a different server. Keeps path after api/ in that if you have api/somecall?test=blah it will forward has /somecall?test=blah.

reverseProxy.js

var express = require('express'),
    request = require('request'),
    url = require('url');

var port = 8080;

var app = express();
app.use(function(req, res, next) {
    var proxyUrl = req.path.match(/^\/api(.*)$/);
    if (proxyUrl) {
        var apiUrl = 'http://localhost:8088' + proxyUrl[1];
        req.pipe(request({
            uri: apiUrl + url.parse(req.url).search,
            method: req.method
        })).pipe(res);
    }
    else {
        next();
    }
});

app.listen(port);
