Bootstrap ships with its own build process. At the time of writing this book, Bootstrap's build process is written with Grunt. It enables you to compile and prepare a custom version of Bootstrap and run the documentation locally. Grunt is just like Gulp: it is a task runner for Node.js. Grunt does not use streams but saves the temporary code in file products.

The tasks for Bootstrap's Grunt build process can be found in the Gruntfile.js file included in the source files. You can use this file to understand which tasks you will have to run to get your code ready for testing in production.

In this chapter, we use Gulp instead of Grunt since Gulp is considered to be more intuitive and much easier to learn. Gulp is newer than Grunt, but its community is growing fast and new plugins are added every day.

Finally, you should note that task runners that link Gulp and Grunt will make your work easier but are not required to run your tasks on Node.js.
