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):

  1. // You can specify which plugins you need
  2. import { Tooltip, Toast, Popover } from 'bootstrap';

Alternatively, if you only need just a few of our plugins, you may import plugins individually as needed:

  1. import Alert from 'bootstrap/js/dist/alert';
  2. ...

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

  1. @import "custom";
  2. @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:

  1. // ...
  2. {
  3. test: /\.(scss)$/,
  4. use: [{
  5. // inject CSS to page
  6. loader: 'style-loader'
  7. }, {
  8. // translates CSS into CommonJS modules
  9. loader: 'css-loader'
  10. }, {
  11. // Run postcss actions
  12. loader: 'postcss-loader',
  13. options: {
  14. // `postcssOptions` is needed for postcss 8.x;
  15. // if you use postcss 7.x skip the key
  16. postcssOptions: {
  17. // postcss plugins, can be exported to postcss.config.js
  18. plugins: function () {
  19. return [
  20. require('autoprefixer')
  21. ];
  22. }
  23. }
  24. }
  25. }, {
  26. // compiles Sass to CSS
  27. loader: 'sass-loader'
  28. }]
  29. }
  30. // ...

Importing Compiled CSS

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

  1. 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.

  1. // ...
  2. module: {
  3. rules: [
  4. {
  5. test: /\.css$/,
  6. use: [
  7. 'style-loader',
  8. 'css-loader'
  9. ]
  10. }
  11. ]
  12. }
  13. // ...
