Heroku buildpack: Node.js with grunt support

This is a fork of Heroku's official Node.js buildpack with added grunt support. Using this buildpack you do not need to commit the results of your grunt tasks (e.g. minification and concatination of files), keeping your repository clean.

After all the default Node.js and NPM build tasks have finished, the buildpack checks if a gruntfile (grunt.js) exists and executes the heroku task by running grunt heroku. For details about grunt and how to define tasks, check out the offical documentation. You must add grunt to the NPM dependencies in your package.json file. If no gruntfile exists, the buildpacks simply skips the grunt step and executes like the standard Node.js buildpack.


Create a new app with this buildpack:

heroku create myapp --buildpack

Or add this buildpack to your current app:

heroku config:add BUILDPACK_URL=

Create your Node.js app and add a gruntfile named grunt.js with a heroku task:

grunt.registerTask('heroku', 'clean less mincss');

Don't forget to add grunt to your dependencies in package.json. If your grunt tasks depend on other pre-defined tasks make sure to add these dependencies as well:

"dependencies": {
    "grunt": "*",
    "grunt-contrib": "*",
    "less": "*"
