Using hands-on examples you will learn about CSS linting, combination, compilation and minification; JavaScript linting, AMD modules, and templates; image processing and optimizing; and creating a local server. More advanced topics include: LiveReload, Test Automation, Modular configuration, and combining tasks. You will see how to scaffold plugins using Grunt init and Yeoman, how to test them with Mocha and Chai, and how to publish them so others can use them.
