Heroku Buildpack for Node.js and gulp.js

Usage

Set your Heroku app's buildpack URL to https://github.com/appstack/heroku-buildpack-nodejs-gulp.git. To be safe, you should really fork this and use your fork's URL.
Run heroku labs:enable user-env-compile to enable environment variable support
Run heroku config:set NODE_ENV=production to set your environment to production (or any other name)
Add a Gulp task called heroku:production that builds your app
Install the dependenies for serving the app: npm install gzippo express --save
Create a simple web server in the root called web.js:

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

app.use(express.logger('dev'));
app.use(gzippo.staticGzip("" + __dirname + "/build"));
app.listen(process.env.PORT || 5000);
