Using Alpine.js to handle JavaScript events in Phoenix LiveView applications significantly enhances your web app’s interactivity.
The PETAL stack#
The PETAL stack consists of:
- Phoenix - The web framework providing robustness and reliability.
- Elixir - The dynamic, functional language designed for scalable and maintainable applications.
- TailwindCSS - A utility-first CSS framework for rapidly building custom designs.
- Alpine.js - A minimal framework for composing JavaScript behaviour, our star today.
- LiveView - Enables rich, real-time user experiences with server-rendered HTML.
In this article, I’ll present the “A” part of the PETAL, which stands for Alpine.js. LiveView’s capability of handling real-time user events is a powerful tool, but using it for a simple UI interaction is like using a sledgehammer to crack a nut. You definitely can, but there are more appropriate tools for that task.
