Nested Express apps. How it should be.

nestedapps.js

// ### The Root application
// ./index.js                   <- lives here
// ./views/index.hbs            <- the view
// ./catsApp                    <- child app

var express = require('express');
var app = express();
var exphbs = require('express-handlebars');
app.engine('hbs', exphbs({defaultLayout: 'single', extname: '.hbs'}));
app.set('view engine', 'hbs');
app.get('/', function(req, res) {
  res.render('index');
})

// This should be it's own instance, or have it's own locality of certain configuration options
// It should be able to have it's own view engine and be able to find views relative to it's root directory
app.use('/cats', require('catsApp'));
app.listen(3000);
 
// ### The Child Application
// ./catsApp/index.js           <- lives here
// ./catsApp/views/index.jade   <-- the view

var express = require('express');
var catsApp = express();
catsApp.set('view engine', 'jade');
catsApp.get('/', function(req, res) {
  res.render('index');
})

modules.export = catsApp;
