Frontend Assets


A new Supercharge applications ships with routes to serve assets. All asset-related routes are located in the app/routes/assets.js file.

The routes defined in the app/routes/assets.js file have static references to the public directory to serve these assets publicly. The Supercharge application boilerplate has predefined folders and files to make it as seamless as possible for you to add your public assets.

Supercharge uses the @hapi/inert plugin to connect the routes to the public directory on your filesystem.

Even though the asset routes reference the public folder, the individual route paths don’t contain the word "public" in the path. For example, CSS files are availabe on URL path /css/{css-file-name}.css and not on /public/css/{css-file-name}.css.


Supercharge serves CSS files from the public/css directory. You’ll find an existing style.css in this directory. This file defines the default layout for the Supercharge start page. You can surely adjust and change the styling to your needs.

Please notice, the Supercharge default layout uses Bootstrap 4 to have a solid foundation for sophisticated user interfaces.

At this point, Supercharge doesn’t ship with an asset pipeline to compile static assets for production. As soon as you integrate a pipeline, point the CSS outputs to the public/css directory.


Supercharge serves JS files from the public/js directory. A new Supercharge installation doesn’t contain any JavaScript file. Nonetheless, you’ll find the public/js folder because it contains a .gitkeep file. The .gitkeep file is a workaround to keep the empty public/js folder in the Supercharge application boilerplate’s git repository. You may remove this file as soon as you add your own JavaScript files.

If you create nested directories inside of public/js, you can reference them in your layouts using the related path. For example, a file located at public/js/code/highlight.js should be referenced in your design like this:

<script src="/js/code/highlight.js"></script>


Supercharge serves images from the public/images directory. In a new Supercharge installation, you’ll find a handful of existing images like the Supercharge logo. Of course, you can go ahead and delete or replace them.
