Webpack

Learn how to include Bootstrap in your project using Webpack.

Installing Bootstrap

Install bootstrap as a Node.js module using npm.

Importing JavaScript

Import Bootstrap’s JavaScript by adding this line to your app’s entry point (usually index.js or app.js):

import 'bootstrap';

Alternatively, you may import plugins individually as needed:

import 'bootstrap/js/dist/util';
import 'bootstrap/js/dist/alert';
...

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. Then, use your main Sass file to import your custom variables, followed by Bootstrap:

@import "custom";
@import "~bootstrap/scss/bootstrap";

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:

...
{
  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
  }]
},
...

Importing Compiled CSS

Alternatively, you may use Bootstrap’s ready-to-use CSS by simply adding this line to your project’s entry point:

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 and css-loader.

...
module: {
  rules: [
    {
      test: /\.css$/,
      use: ['style-loader', 'css-loader']
    }
  ]
}
...
