Internal routing within a single node process using express

express.js

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

var port = process.env.PORT || 5000

app.get('/api', function(req, res) {
  res.send('I am from the API')
})

app.get('/internal', function(req, res) {
  request('http://localhost:'+port+'/api').pipe(res) // Will send 'I am from the API'
})

app.listen(port)

That kind of looks external to me :-p.

Agreed!
