For more information on what generator-lessapp can do for you, take a look at the Grunt tasks used in our package.json.

Getting Started

  • Install: npm install -g generator-lessapp
  • Run: yo lessapp
  • Run grunt for building and grunt serve for preview *

Third-Party Dependencies


Third-party dependencies are managed with bower-install. Add new dependencies using Bower and then run the Grunt task to load them:

  bower install --save jquery
  grunt bowerInstall

This works if the package author has followed the Bower spec. If the files are not automatically added to your index.html, check with the package's repo for support and/or file an issue with them to have it updated.

To manually add dependencies, bower install depName --save to get the files, then add a script or style tag to your index.html or an other appropriate place.

The components are installed in the root of the project at /bower_components. To reference them from the grunt serve web app index.html file, use src="bower_components" or src="/bower_components". Treat the references as if they were a sibling to index.html.

Testing Note: a project checked into source control and later checked out, needs to have bower install run from the test folder as well as from project root.

Grunt Serve Note

Note: grunt server was previously used for previewing in earlier versions of the project and is being deprecated in favor of grunt serve.


  • --skip-install

    Skips the automatic execution of bower and npm after scaffolding has finished.

  • --test-framework=<framework>

    Defaults to mocha. Can be switched for another supported testing framework like jasmine.

  • --coffee

    Add support for CoffeeScript.
