Real-Time & LiveView

Why not React + Socket.io? Phoenix LiveView renders interactive, real-time UI on the server in pure Elixir. No JavaScript build pipeline, no API layer, no client-side state management. Channels handle raw WebSocket communication. PubSub broadcasts events across distributed nodes. Presence tracks online users with CRDTs. All of this ships with Phoenix — zero additional services.
