Phoenix Framework

framework

phoenixframework.org · 2014

  • Web framework for Elixir that exploits BEAM’s concurrency model to handle massive numbers of persistent connections (channels, LiveView)
  • LiveView eliminates the SPA/API split by rendering server-side HTML and pushing diffs over WebSockets — real-time UIs without JavaScript frameworks
  • Each request and each WebSocket connection runs in its own BEAM process, inheriting fault isolation and preemptive scheduling for free
