## Installing Bootstrap
[Install bootstrap]({{< docsref "/getting-started/download#npm" >}}) as a Node.js module using npm.
## Importing JavaScript
Import [Bootstrap's JavaScript]({{< docsref "/getting-started/javascript" >}}) by adding this line to your app's entry point (usually `index.js` or `app.js`):
```js
// You can specify which plugins you need
import { Tooltip, Toast, Popover } from 'bootstrap';
```
Alternatively, if you only need just a few of our plugins, you may **import plugins individually** as needed:
```js
import Alert from 'bootstrap/js/dist/alert';
...
```
Bootstrap depends on [Popper](https://popper.js.org/), which is specified in the `peerDependencies` property.
This means that you will have to make sure to add it to your `package.json` using `npm install @popperjs/core`.
## 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]({{< docsref "/customize/sass" >}}). Then, use your main Sass file to import your custom variables, followed by Bootstrap:
```scss
@import "custom";
@import "~bootstrap/scss/bootstrap";
```
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/webpack-contrib/postcss-loader) with [Autoprefixer](https://github.com/postcss/autoprefixer#webpack). With minimal setup, your webpack config should include this rule or similar:
```js
// ...
{
test: /\.(scss)$/,
use: [{
// inject CSS to page
loader: 'style-loader'
}, {
// translates CSS into CommonJS modules
loader: 'css-loader'
}, {
// Run postcss actions
loader: 'postcss-loader',
options: {
// `postcssOptions` is needed for postcss 8.x;
// if you use postcss 7.x skip the key
postcssOptions: {
// postcss plugins, can be exported to postcss.config.js
plugins: function () {
return [
require('autoprefixer')
];
}
}
}
}, {
// compiles Sass to CSS
loader: 'sass-loader'
}]
}
// ...
```
### Importing Compiled CSS
Alternatively, you may use Bootstrap's ready-to-use CSS by simply adding this line to your project's entry point:
```js
import 'bootstrap/dist/css/bootstrap.min.css';
```
In this case you may use your existing rule for `css` without any special modifications to webpack config, except you don't need `sass-loader` just [style-loader](https://github.com/webpack-contrib/style-loader) and [css-loader](https://github.com/webpack-contrib/css-loader).
```js
// ...
module: {
rules: [
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
}
]
}
// ...
```
