How to write reusable components in Phoenix LiveView

Phoenix is an HTTP routing framework for the Elixir language that is commonly used to create endpoints returning JSON or HTML. The article delves into Phoenix LiveView, a server-side, stateful pattern that enables real-time communication between the frontend and backend through WebSocket connections, contrasting it with frontend frameworks like React and Svelte, which manage state on the client side. The piece explores how LiveView fits into the frontend by maintaining state on the server and updating the UI through WebSocket events, essentially creating a single-page application experience. It discusses different component types within Phoenix, such as live components and markup components, highlighting their role in encapsulating markup and styling for consistency and reusability. The article also demonstrates how to write reusable components, focusing on creating a button and container to maintain uniformity across projects, ultimately offering a streamlined approach to building applications with Phoenix components.
