Hotwire

Hotwire is a JavaScript framework designed to take full advantage of server-side generated HTML. It is comprised of 3 core components:

1. Turbo handles navigation, form submissions, page components, and updates without writing any custom JavaScript.
2. Stimulus provides a framework for when you need custom JavaScript to add functionality to the page.
3. Native allows you to make hybrid mobile apps by embedding your web app and progressively enhancing it with native mobile features.

We haven’t written any JavaScript yet, but we have been using Hotwire on the frontend. For instance, the form you created to add and edit a product was powered by Turbo.
