Build tools

Learn how to use CoreUI's included npm scripts to compile source code, run tests, and more.

Tooling setup

Bootstrap uses npm scripts for its build system. Our package.json includes convenient methods for working with the framework, including compiling code, running tests, and more.

To use our build system and run our documentation locally, you’ll need a copy of CoreUI’s source files and Node. Follow these steps and you should be ready to rock:

  1. Download and install Node.js, which we use to manage our dependencies.
  2. Navigate to the root /bootstrap directory and run npm install to install our local dependencies listed in package.json.

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:

Task Description
npm run dist npm run dist creates the /dist/ directory with compiled files. Uses Sass, Autoprefixer, and terser.
npm test Same as npm run dist plus it runs tests locally

Run npm run to see all the npm scripts.

Autoprefixer

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.

Troubleshooting

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