  6. • Task based CLI tool • Runs on Node.js •

    Uses NPM to extend functionality • Massive eco-system • Functionality similar to most *akefiles Grunt
  7. How do I use it? $ npm install grunt-cli -g

    $ touch Gruntfile.js $ npm install grunt-contrib-jshint
  8. Edit your Gruntfile

  16. CSSProc Utility to replace local asset paths in CSS files

    with CDN versions.
  17. Asset Loader • Builds YUI module meta data rollup file

    for use by YUI Loader on the client. • Leverages express-yui (modown). • Example: http://bit. ly/1elVgxN
  18. Asset Deployment • Deploy assets to CDN asynchronously. • Set

    custom headers for assets (e.g. CORS).
  19. Scaffolding with grunt-init

  20. • Custom scaffolding to build project folder and file structure.

    • Provides prompts to customize your project. • Works great but “almost” deprecated in favor of Yeoman generators.
  21. Sniffers

  22. • Grunt tasks that ensure your applications code quality guidelines

    are met. • Sniffers we use: ◦ console.log checks ◦ Template helper enforcement ◦ i18n resource bundle verifications
  23. Release

  24. • Rollup task to run a series of tasks. •

    Used at build time. • Runs cssproc, imagemin, asset loader and asset deployment.
  25. CSSProc and Sniffer tasks will open sourced in the near
