basic example node.js (+express +jade) application configured to run in Heroku (views_layout.jade and views_home.jade should just be "layout.jade" and "home.jade" inside the "views" subdirectory) (public_home.js should just be "home.js" inside the "public" subdirectory)

package.json

{
  "name": "example",
  "version": "0.0.1",
  "private": true,
  "engines": {
    "node": "0.10.x",
    "npm": "1.2.x"
  },
  "dependencies": {
    "express": "*",
    "jade": "*"
  }
}

Procfile

web: node server.js

public_home.js

$(function(){
  alert('Hello world.');
});

server.js

var express = require('express');
var app = module.exports = express();

app.set('view engine', 'jade');
app.set('views', __dirname + '/views');

app.use(express.static(__dirname + '/public'));
app.use(app.router);

app.get('/', function(req, res){
  res.render('home', {sayHelloTo: 'world'});
});

if(!module.parent){
  app.listen(process.env.PORT || 3000, function(){
    console.log('up and running');
  });
}

Thanks for the gist, Troy. However, it looks like there have been some changes since you posted, and with this example, Heroku is throwing errors on page load.

When running from the heroku console, it talks about deprecation of app.router

$ heroku run bash
Running bash on ⬢ someapp... up, run.3105 (Free)
~ $ ls
Procfile  node_modules  package.json  public  server.js  views
~ $ node server.js 

Error: 'app.router' is deprecated!
Please see the 3.x to 4.x migration guide for details on how to update your app.
