Set your Heroku app's buildpack URL to
https://github.com/davidmfoley/heroku-buildpack-nodejs-gulp-bower.git. To be safe, you should really fork this and use your fork's URL.
heroku labs:enable user-env-compile to enable environment variable support
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
Add a single line
Procfile to the root to serve the app via node:
web: node index.js
(edit to fit your case)
