Download Bootstrap

Source files

Want to compile Bootstrap with your project's asset pipeline? Choose this option to download our source Sass, JavaScript, and documentation files. Requires a Sass compiler, Autoprefixer, postcss-flexbugs-fixes, and [some setup]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/build-tools/#tooling-setup).

Download source

Bootstrap CDN

Skip the download and use the Bootstrap CDN to deliver Bootstrap's compiled CSS and JS to your project.

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, Autoprefixer, and postcss-flexbugs-fixes for a setup that matches our official compiled versions.

npm

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

{% highlight bash %} npm install bootstrap@{{ site.current_version }} {% endhighlight %}

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)

RubyGems

Install Bootstrap in your Ruby apps using Bundler (recommended) and RubyGems by adding the following line to your Gemfile:

{% highlight ruby %} gem 'bootstrap', '~> 4.0.0.alpha6' {% endhighlight %}

Alternatively, if you're not using Bundler, you can install the gem by running this command:

{% highlight bash %} gem install bootstrap -v 4.0.0.alpha6 {% endhighlight %}

See the gem's README for further details.

Composer

You can also install and manage Bootstrap's Sass and JavaScript using Composer:

{% highlight bash %} composer require twbs/bootstrap:{{ site.current_version }} {% endhighlight %}

Bower

Install and manage Bootstrap's Sass and JavaScript using Bower.

{% highlight bash %} bower install bootstrap#v{{ site.current_version }} {% endhighlight %}

NuGet

If you develop in .NET, you can also install and manage Bootstrap's CSS or Sass and JavaScript using NuGet:

{% highlight powershell %} Install-Package bootstrap -Pre {% endhighlight %}

{% highlight powershell %} Install-Package bootstrap.sass -Pre {% endhighlight %}

The -Pre is required until Bootstrap v4 has a stable release.
