Extremely simple reverse proxy in Node.js using Express and Request

index.js

var express = require('express');
var app = express();
var request = require('request');


app.get('/', function(request, response) {
  response.send("OK")
});

//now you can go to domain.com/(URI ENCODED VERSION OF A URL) to access that page
//example: domain.com/https%3A%2F%2Fgoogle.com to get the Google homepage
app.get('/:d', function(req,res){
  res.setHeader('Access-Control-Allow-Origin', '*');
  request(decodeURIComponent(req.params.d)).pipe(res);
})

var listener = app.listen(process.env.PORT, function() {
  console.log('Your app is listening on port ' + listener.address().port);
});
