Installing Bootstrap
[Install bootstrap]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/download/#npm) as a Node.js module using npm.
Importing JavaScript
Import [Bootstrap's JavaScript]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/javascript/) by adding this line to your app's entry point (usually index.js or app.js):
{% highlight js %} import 'bootstrap'; {% endhighlight %}
Alternatively, you may import plugins individually as needed:
{% highlight js %} import 'bootstrap/js/dist/util'; import 'bootstrap/js/dist/alert'; ... {% endhighlight %}
Bootstrap depends on jQuery and Popper,
which are specified in the peerDependencies property; this means that you will have to make sure to add both of them
to your package.json using npm install --save jquery popper.js.
Importing Styles
Importing Precompiled Sass
To enjoy the full potential of Bootstrap and customize it to your needs, use the source files as a part of your project's bundling process.
First, create your own _custom.scss and use it to override the [built-in custom variables]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/theming/). Then, use your main Sass file to import your custom variables, followed by Bootstrap:
{% highlight scss %} @import "custom"; @import "~bootstrap/scss/bootstrap"; {% endhighlight %}
For Bootstrap to compile, make sure you install and use the required loaders: sass-loader, postcss-loader with Autoprefixer. With minimal setup, your webpack config should include this rule or similar:
{% highlight js %} ... { test: /.(scss)$/, use: [{ loader: 'style-loader', // inject CSS to page }, { loader: 'css-loader', // translates CSS into CommonJS modules }, { loader: 'postcss-loader', // Run postcss actions options: { plugins: function () { // postcss plugins, can be exported to postcss.config.js return [ require('autoprefixer') ]; } } }, { loader: 'sass-loader' // compiles Sass to CSS }] }, ... {% endhighlight %}
Importing Compiled CSS
Alternatively, you may use Bootstrap's ready-to-use CSS by simply adding this line to your project's entry point:
{% highlight js %} import 'bootstrap/dist/css/bootstrap.min.css'; {% endhighlight %}
In this case you may use your existing rule for css without any special modifications to webpack config, except you don't need sass-loader just style-loader and css-loader.
{% highlight js %} ... module: { rules: [ { test: /.css$/, use: ['style-loader', 'css-loader'] } ] } ... {% endhighlight %}
