Webpack and bundlers
Learn how to include Bootstrap in your project using Webpack or other bundlers.
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
oder app.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:
import Alert from 'bootstrap/js/dist/alert';
...
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:
@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)$/,
use: [{
// inject CSS to page
loader: 'style-loader'
}, {
// translates CSS into CommonJS modules
loader: 'css-loader'
}, {
// Run postcss actions
loader: 'postcss-loader',
options: {
// `postcssOptions` is needed for postcss 8.x;
// if you use postcss 7.x skip the key
postcssOptions: {
// postcss plugins, can be exported to postcss.config.js
plugins: function () {
return [
require('autoprefixer')
];
}
}
}
}, {
// compiles Sass to CSS
loader: 'sass-loader'
}]
}
// ...
Importing Compiled CSS
Alternatively, you may use Bootstrap’s ready-to-use CSS by simply adding this line to your project’s entry point:
import 'bootstrap/dist/css/bootstrap.min.css';
In this case you may use your existing rule for css
without any special modifications to webpack config, except you don’t need sass-loader
just style-loader and css-loader.
// ...
module: {
rules: [
{
test: /\.css$/,
use: [
'style-loader',
'css-loader'
]
}
]
}
// ...
