Grunt is an extremely useful Node.js package to automate lots of development and continuous integration tasks. The Grunt eco-system has lots of packages available on npm. This enables us to quickly setup our development/continuous integration environment. Grunt tasks mostly have two required properties. An files array, which is used to configure on what files the tasks is executed, and an options property which configures some task specific settings. The files array supports the globbing and minimatch pattern to match files based on the provided expression. So what tasks could you use for your projects, or for which project can you use Grunt? How do I configure Grunt tasks? How do I execute them? All these questions I try to answer for you in this article.
