## 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](https://jquery.com/) and [Popper](https://popper.js.org/),
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](https://github.com/webpack-contrib/sass-loader), [postcss-loader](https://github.com/postcss/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack). With minimal setup, your webpack config should include this rule or similar:
{% highlight js %}
...
{
test: /\.(scss)$/,
use: [{
loader: 'style-loader', // inject CSS to page
}, {
loader: 'css-loader', // translates CSS into CommonJS modules
}, {
loader: 'postcss-loader', // Run postcss actions
options: {
plugins: function () { // postcss plugins, can be exported to postcss.config.js
return [
require('autoprefixer')
];
}
}
}, {
loader: 'sass-loader' // compiles Sass to CSS
}]
},
...
{% endhighlight %}
### Importing Compiled CSS
Alternatively, you may use Bootstrap's ready-to-use CSS by simply adding this line to your project's entry point:
{% highlight js %}
import 'bootstrap/dist/css/bootstrap.min.css';
{% endhighlight %}
In this case you may use your existing rule for `css` without any special modifications to webpack config, except you don't need `sass-loader` just [style-loader](https://github.com/webpack-contrib/style-loader) and [css-loader](https://github.com/webpack-contrib/css-loader).
{% highlight js %}
...
module: {
rules: [
{
test: /\.css$/,
use: ['style-loader', 'css-loader']
}
]
}
...
{% endhighlight %}
