Install Parcel

Install Bootstrap

Install bootstrap as a Node.js module using npm.

Bootstrap depends on Popper , which is specified in the peerDependenciesproperty. This means that you will have to make sure to add both of them to your package.jsonusing npm install @popperjs/core.

When all will be completed, your project will be structured like this:

project-name/
├── build/
├── node_modules/
│   └── bootstrap/
│   └── popper.js/
├── scss/
│   └── custom.scss
├── src/
│   └── index.html
│   └── index.js
└── package.json

Importing JavaScript

Import Bootstrap's JavaScript in your app's entry point (usually src/index.js). You can import all our plugins in one file or separately if you require only a subset of them.

// Import all plugins
import * as bootstrap from 'bootstrap';

// Or import only needed plugins
import { Tooltip as Tooltip, Toast as Toast, Popover as Popover } from 'bootstrap';

// Or import just one
import Alert as Alert from '../node_modules/bootstrap/js/dist/alert';

Importing CSS

To utilize the full potential of Bootstrap and customize it to your needs, use the source files as a part of your project's bundling process.

Create your own scss/custom.scssto import Bootstrap's Sass files and then override the built-in custom variables .

Build app

Include src/index.jsbefore the closing </body>tag.

<!doctype html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
  </head>
  <body>
    <script src="./index.js"></script>
  </body>
</html>

Add devand buildscripts in your package.jsonfile.

"scripts": {
  "dev": "parcel ./src/index.html",
  "prebuild": "npx rimraf build",
  "build": "parcel build --public-url ./ ./src/index.html --experimental-scope-hoisting --out-dir build"
}
