<h2 id="what-is-webpack">What is Webpack?<a class="anchor-link" href="#what-is-webpack"> </a></h2>
|
||
<p><a href="https://webpack.js.org/">Webpack</a> is a JavaScript module bundler that processes modules and their dependencies to generate static assets. It simplifies managing complex web applications with multiple files and dependencies.</p>
|
||
<h2 id="setup">Setup<a class="anchor-link" href="#setup"> </a></h2>
|
||
<p>We’re building a Webpack project with Bootstrap from scratch, so there are some prerequisites and upfront steps before we can really get started. This guide requires you to have Node.js installed and some familiarity with the terminal.</p>
|
||
<ol>
|
||
<li>
|
||
<p><strong>Create a project folder and set up npm.</strong> We'll create the <code>my-project</code> folder and initialize npm with the <code>-y</code> argument to avoid it asking us all the interactive questions.</p>
|
||
<script type="module" src="/docs/5.3/assets/Code.astro_astro_type_script_index_0_lang.5BTJN8ix.js"></script> <div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">mkdir</span> my-project <span class="token operator">&&</span> <span class="token builtin class-name">cd</span> my-project
|
||
</span><span class="token span line"><span class="token function">npm</span> init <span class="token parameter variable">-y</span>
|
||
</span></code></pre> </div> </div>
|
||
</li>
|
||
<li>
|
||
<p><strong>Install Webpack.</strong> Next we need to install our Webpack development dependencies: <code>webpack</code> for the core of Webpack, <code>webpack-cli</code> so we can run Webpack commands from the terminal, and <code>webpack-dev-server</code> so we can run a local development server. Additionally, we'll install <code>html-webpack-plugin</code> to be able to store our <code>index.html</code> in <code>src</code> directory instead of the default <code>dist</code> one. We use <code>--save-dev</code> to signal that these dependencies are only for development use and not for production.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">npm</span> i --save-dev webpack webpack-cli webpack-dev-server html-webpack-plugin
|
||
</span></code></pre> </div> </div>
|
||
</li>
|
||
<li>
|
||
<p><strong>Install Bootstrap.</strong> 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.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">npm</span> i <span class="token parameter variable">--save</span> bootstrap @popperjs/core
|
||
</span></code></pre> </div> </div>
|
||
</li>
|
||
<li>
|
||
<p><strong>Install additional dependencies.</strong> 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.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">npm</span> i --save-dev autoprefixer css-loader postcss-loader sass sass-loader style-loader
|
||
</span></code></pre> </div> </div>
|
||
</li>
|
||
</ol>
|
||
<p>Now that we have all the necessary dependencies installed, we can get to work creating the project files and importing Bootstrap.</p>
|
||
<h2 id="project-structure">Project structure<a class="anchor-link" href="#project-structure"> </a></h2>
|
||
<p>We’ve already created the <code>my-project</code> folder and initialized npm. Now we'll also create our <code>src</code> and <code>dist</code> folders to round out the project structure. Run the following from <code>my-project</code>, or manually create the folder and file structure shown below.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">mkdir</span> <span class="token punctuation">{</span>src,src/js,src/scss<span class="token punctuation">}</span>
|
||
</span><span class="token span line"><span class="token function">touch</span> src/index.html src/js/main.js src/scss/styles.scss webpack.config.js
|
||
</span></code></pre> </div> </div>
|
||
<p>When you’re done, your complete project should look like this:</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-text"><code is:raw class="language-text">my-project/

|
||
└── webpack.config.js
|
||
</code></pre> </div> </div>
|
||
<p>At this point, everything is in the right place, but Webpack won’t work because we haven’t filled in our <code>webpack.config.js</code> yet.</p>
|
||
<h2 id="configure-webpack">Configure Webpack<a class="anchor-link" href="#configure-webpack"> </a></h2>
|
||
<p>With dependencies installed and our project folder ready for us to start coding, we can now configure Webpack and run our project locally.</p>
|
||
<ol>
|
||
<li>
|
||
<p><strong>Open <code>webpack.config.js</code> in your editor.</strong> 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 (<code>dist</code>), and how the development server should behave (pulling from the <code>dist</code> folder with hot reload).</p>

<p><strong>Next we fill in our <code>src/index.html</code>.</strong> 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.

|

<p>Here’s a recap of why we need all these loaders. <code>style-loader</code> injects the CSS into a <code><style></code> element in the <code><head></code> of the HTML page, <code>css-loader</code> helps with using <code>@import</code> and <code>url()</code>, <code>postcss-loader</code> is required for Autoprefixer, and <code>sass-loader</code> allows us to use Sass.</p>
|
||
<p><strong>Note:</strong> Sass deprecation warnings are shown when compiling source Sass files with the latest versions of Dart Sass. This does not prevent compilation or usage of Bootstrap. We’re <a href="https://github.com/twbs/bootstrap/issues/40962">working on a long-term fix</a>, but in the meantime these deprecation notices can be ignored.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Now, let’s import Bootstrap’s CSS.</strong> Add the following to <code>src/scss/styles.scss</code> to import all of Bootstrap’s source Sass.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-scss"><code is:raw class="language-scss"><span class="token comment">// Import all of Bootstrap’s CSS</span>

|
||
</li>
|
||
<li>
|
||
<p><strong>Next we load the CSS and import Bootstrap’s JavaScript.</strong> Add the following to <code>src/js/main.js</code> to load the CSS and import all of Bootstrap’s JS. Popper will be imported automatically through Bootstrap.</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-js"><code is:raw class="language-js"><span class="token comment">// Import our custom CSS</span>

</code></pre> </div> </div>
|
||
<p><em><a href="/docs/5.3/getting-started/javascript/">Read our JavaScript docs</a> for more information on how to use Bootstrap’s plugins.</em></p>
|
||
</li>
|
||
<li>
|
||
<p><strong>And you’re done! 🎉</strong> With Bootstrap’s source Sass and JS fully loaded, your local development server should now look like this:</p>
|
||
<img class="img-fluid" src="/docs/5.3/assets/img/guides/webpack-dev-server-bootstrap.png" alt="Webpack dev server running with Bootstrap"/>
|
||
<p>Now you can start adding any Bootstrap components you want to use. Be sure to <a href="https://github.com/twbs/examples/tree/main/webpack">check out the complete Webpack example project</a> for how to include additional custom Sass and optimize your build by importing only the parts of Bootstrap’s CSS and JS that you need.</p>

<h2 id="production-optimizations">Production optimizations<a class="anchor-link" href="#production-optimizations"> </a></h2>
|

<p>Depending on your setup, you may want to implement some additional security and speed optimizations useful for running the project in production. Note that these optimizations are not applied on <a href="https://github.com/twbs/examples/tree/main/webpack">the Webpack example project</a> and are up to you to implement.</p>

|
||
<p>The <code>style-loader</code> we configured above conveniently emits CSS into the bundle so that manually loading a CSS file in <code>dist/index.html</code> isn’t necessary. This approach may not work with a strict Content Security Policy, however, and it may become a bottleneck in your application due to the large bundle size.</p>
|
||
<p>To separate the CSS so that we can load it directly from <code>dist/index.html</code>, use the <code>mini-css-extract-loader</code> Webpack plugin.</p>
|
||
<p>First, install the plugin:</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-sh"><code is:raw class="language-sh"><span class="token span line"><span class="token function">npm</span> <span class="token function">install</span> --save-dev mini-css-extract-plugin
|
||
</span></code></pre> </div> </div>
|
||
<p>Then instantiate and use the plugin in the Webpack configuration:</p>
|
||
<div class="bd-code-snippet"> <div class="bd-clipboard"> <button type="button" class="btn-clipboard"> <svg class="bi" role="img" aria-label="Copy"> <use xlink:href="#clipboard"></use> </svg> </button> </div> <div class="highlight"> <pre class="language-diff"><code is:raw class="language-diff"><span class="token coord">--- a/webpack.config.js</span>

<p>Bootstrap’s CSS includes multiple references to SVG files via inline <code>data:</code> URIs. If you define a Content Security Policy for your project that blocks <code>data:</code> URIs for images, then these SVG files will not load.
