Phoenix LiveView is an Elixir library that enables rich, real-time user experiences by using server-rendered HTML over WebSockets, providing seamless dynamic interactivity without needing front-end JavaScript frameworks. It integrates deeply with Phoenix and ships by default in new Phoenix applications. LiveView brings a unified experience to building web applications. You no longer have to split work between client and server, across different toolings, layers, and abstractions. Instead, LiveView enriches the server with a declarative and powerful model while keeping your code closer to your data (and ultimately your source of truth).

Features

  • Declarative rendering of server-side HTML with WebSocket (and fallback) communication
  • Efficient diffs over the wire: only changed parts are transmitted after initial render
  • Real-time form validation and file uploads with live previews and progress indicators
  • Rich API for UI events: phx-click, phx-submit, phx-hook, optimistic updates via JS commands
  • Supports stateful components, HEEx templating, slots, verified routes, and live navigation
  • Includes testing tools, latency simulator, and rich debugging options
