**Want to skip to the end?** Download the source code and working demo for this guide from the [twbs/examples repository](https://github.com/twbs/examples/tree/main/webpack). You can also [open the example in StackBlitz](https://stackblitz.com/github/twbs/examples/tree/main/webpack?file=index.html) for live editing.

## Setup
We're building a Webpack project with Bootstrap from scratch, so there are some prerequisites and up front steps before we can really get started. This guide requires you to have Node.js installed and some familiarity with the terminal.
1. **Create a project folder and setup npm.** We'll create the `my-project` folder and initialize npm with the `-y` argument to avoid it asking us all the interactive questions.
```sh
mkdir my-project && cd my-project
npm init -y
```
2. **Install Webpack.** Next we need to install our Webpack development dependencies: `webpack` for the core of Webpack, `webpack-cli` so we can run Webpack commands from the terminal, and `webpack-dev-server` so we can run a local development server. Additionally, we'll install `html-webpack-plugin` to be able to store our `index.html` in `src` directory instead of the default `dist` one. We use `--save-dev` to signal that these dependencies are only for development use and not for production.
```sh
npm i --save-dev webpack webpack-cli webpack-dev-server html-webpack-plugin
```
3. **Install Bootstrap.** Now we can install Bootstrap. We'll also install Popper since our dropdowns, popovers, and tooltips depend on it for their positioning. If you don't plan on using those components, you can omit Popper here.
```sh
npm i --save bootstrap @popperjs/core
```
4. **Install additional dependencies.** In addition to Webpack and Bootstrap, we need a few more dependencies to properly import and bundle Bootstrap's CSS and JS with Webpack. These include Sass, some loaders, and Autoprefixer.
```sh
npm i --save-dev autoprefixer css-loader postcss-loader sass sass-loader style-loader
```
Now that we have all the necessary dependencies installed, we can get to work creating the project files and importing Bootstrap.
## Project structure
We've already created the `my-project` folder and initialized npm. Now we'll also create our `src` and `dist` folders to round out the project structure. Run the following from `my-project`, or manually create the folder and file structure shown below.
```sh
mkdir {src,src/js,src/scss}
touch src/index.html src/js/main.js src/scss/styles.scss webpack.config.js
```
When you're done, your complete project should look like this:
```text
my-project/
├── src/
│ ├── js/
│ │ └── main.js
│ ├── scss/
│ │ └── styles.scss
│ └── index.html
├── package-lock.json
├── package.json
└── webpack.config.js
```
At this point, everything is in the right place, but Webpack won't work because we haven't filled in our `webpack.config.js` yet.
## Configure Webpack
With dependencies installed and our project folder ready for us to start coding, we can now configure Webpack and run our project locally.
1. **Open `webpack.config.js` in your editor.** Since it's blank, we'll need to add some boilerplate config to it so we can start our server. This part of the config tells Webpack where to look for our project's JavaScript, where to output the compiled code to (`dist`), and how the development server should behave (pulling from the `dist` folder with hot reload).
```js
'use strict'
const path = require('path')
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
mode: 'development',
entry: './src/js/main.js',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist')
},
devServer: {
static: path.resolve(__dirname, 'dist'),
port: 8080,
hot: true
},
plugins: [
new HtmlWebpackPlugin({ template: './src/index.html' })
]
}
```
2. **Next we fill in our `src/index.html`.** This is the HTML page Webpack will load in the browser to utilize the bundled CSS and JS we'll add to it in later steps. Before we can do that, we have to give it something to render and include the `output` JS from the previous step.
```html
Bootstrap w/ Webpack
Hello, Bootstrap and Webpack!
```
We're including a little bit of Bootstrap styling here with the `div class="container"` and `
