Building a Basic Phoenix LiveView Application

This content is a tutorial by Mike Clark that introduces Phoenix LiveView by demonstrating how to build a simple light controller with features such as turning off and on, and adjusting the brightness. The tutorial begins with the creation of a new Phoenix app and setting up the server. It continues with adding a live route to the router, creating a LiveView module and using live templates (HEEx) for dynamic content. The tutorial also explains how LiveView processes user events through handle_event callbacks and updates the UI state without custom JavaScript. The interactive components include buttons that can dim or brighten the simulated light. The article wraps up with a summary of the LiveView programming model and how state changes trigger automatic view rendering, emphasizing the ease and efficiency of building interactive applications with Elixir and LiveView.
