Installation

Include Bootstrap’s source Sass and JavaScript files via npm, Composer or Meteor. Package managed installs don’t include documentation, but do include our build system and readme.

   $ npm install bootstrap
   $ gem install bootstrap -v 4.3.1

Download Bootstrap to get the compiled CSS and JavaScript, source code, or include it with your favorite package managers like npm, RubyGems, and more.

Compiled CSS and JS

Download ready-to-use compiled code for Bootstrap v4.3.1 to easily drop into your project, which includes:

  • Compiled and minified CSS bundles

  • Compiled and minified JavaScript plugins

This doesn’t include documentation, source files, or any optional JavaScript dependencies (jQuery and Popper.js).

Source files

Compile Bootstrap with your own asset pipeline by downloading our source Sass, JavaScript, and documentation files. This option requires some additional tooling:

  • Sass compiler (Libsass or Ruby Sass is supported) for compiling your CSS.

  • Autoprefixer for CSS vendor prefixing

Should you require build tools, they are included for developing Bootstrap and its docs, but they’re likely unsuitable for your own purposes.

Package managers

Pull in Bootstrap’s source files into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will require a Sass compiler and Autoprefixer for a setup that matches our official compiled versions.

npm

Install Bootstrap in your Node.js powered apps with the npm package:

  $ npm install bootstrap

require('bootstrap') will load all of Bootstrap’s jQuery plugins onto the jQuery object. The bootstrap module itself does not export anything. You can manually load Bootstrap’s jQuery plugins individually by loading the /js/*.js files under the package’s top-level directory.

Bootstrap’s package.json contains some additional metadata under the following keys:

  • sass - path to Bootstrap’s main Sass source file

  • style - path to Bootstrap’s non-minified CSS that’s been precompiled using the default settings (no customization)
