Compiling CSS and JavaScript

Bootstrap uses Grunt with convenient methods for working with the framework. It's how we compile our code, run tests, and more. To use it, install the required dependencies as directed and then run some Grunt commands.

Install Grunt

From the command line:

1. Install grunt-cli globally with npm install -g grunt-cli.
2. Navigate to the root /bootstrap directory, then run npm install. npm will look at package.json and automatically install the necessary local dependencies listed there.

When completed, you'll be able to run the various Grunt commands provided from the command line.

Unfamiliar with npm? Don't have node installed? That's a-okay. npm stands for node packaged modulesand is a way to manage development dependencies through node.js. Download and install node.js before proceeding.

Available Grunt commands

Build - grunt

Run grunt to run tests locally and compile the CSS and JavaScript into /dist. Uses Less and UglifyJS.

Only compile CSS and JavaScript - grunt dist

grunt dist creates the /dist directory with compiled files. Uses Less and UglifyJS.

Tests - grunt test

Runs JSHint and QUnit tests headlessly in PhantomJS (used for CI).

Watch - grunt watch

This is a convenience method for watching just Less files and automatically building them whenever you save.
