Learn how to use Bootstrap’s included npm scripts to build our documentation, compile source code, run tests, and more.
To use our build system and run our documentation locally, you’ll need a copy of Bootstrap’s source files and Node. Follow these steps and you should be ready to rock:
- Download and install Node.js, which we use to manage our dependencies.
- Navigate to the root
/bootstrapdirectory and run
npm installto install our local dependencies listed in package.json.
- Install Ruby, install Bundler with
gem install bundler, and finally run
bundle install. This will install all Ruby dependencies, such as Jekyll and plugins.
- Windows users: Read this guide to get Jekyll up and running without problems.
When completed, you’ll be able to run the various commands provided from the command line.
Using NPM scripts
Our package.json includes the following commands and tasks:
npm run dist
npm run dist creates the
/dist directory with compiled files. Uses Sass, Autoprefixer, and UglifyJS.
npm run dist plus it runs tests locally
npm run docs
npm run docs-serve.
npm run to see all the npm scripts.
Bootstrap uses Autoprefixer (included in our build process) to automatically add vendor prefixes to some CSS properties at build time. Doing so saves us time and code by allowing us to write key parts of our CSS a single time while eliminating the need for vendor mixins like those found in v3.
We maintain the list of browsers supported through Autoprefixer in a separate file within our GitHub repository. See /.browserslistrc for details.
Running our documentation locally requires the use of Jekyll, a decently flexible static site generator that provides us: basic includes, Markdown-based files, templates, and more. Here’s how to get it started:
- Run through the tooling setup above to install Jekyll (the site builder) and other Ruby dependencies with
- From the root
npm run docs-servein the command line.
http://localhost:9001in your browser, and voilà.

Should you encounter problems with installing dependencies, uninstall all previous dependency versions (global and local). Then, rerun
