"Discover the simplicity of customizing Bootstrap 5 with an easy-to-use online tool

When I was using Bootstrap 3, there was a convenient tool that allowed me to customize which features I wanted in the minified CSS/JS files to improve loading time.

Now, as I delve into the documentation for Bootstrap 5, I find myself struggling to understand how to achieve the same customization. Even after going through the optimize page, I couldn't find the information I need.

Can someone please guide me on how to include only the necessary features in the minified files for Bootstrap 5?

Answer №1

Although Bootstrap's documentation suggests that a bundler is necessary to load specific Bootstrap component scripts, it is possible to utilize ES6 imports to control what gets loaded. Thankfully, modern browsers support this feature.

Instead of loading all the extensive distribution files, you can create a customized script that imports only the necessary components aligned with the SCSS files you are using. Here is an example of how this can be achieved:

<head>
  <script src="https://cdnjs.../popper.js/.../popper.min.js"></script>

  <script type="module">
    import '/bootstrap/main/js/dist/tooltip.js';
  </script>

  <script>
    let tooltipTriggerList = []
      .slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]'))
    let tooltipList = tooltipTriggerList.map(function(tooltipTriggerEl) {
      return new bootstrap.Tooltip(tooltipTriggerEl)
    })
  </script>
</head>

<body class="p-4">
  <p title="A tooltip." data-bs-toggle="tooltip">Hover for a Bootstrap Tooltip.</p>
</body>

Remember, the imported script files must be served with the appropriate CORS headers and MIME type application/javascript to avoid encountering errors.
