phoenix-api-channels
Phoenix APIs, Channels, and Presence (Elixir/BEAM)
Phoenix excels at REST/JSON APIs and WebSocket Channels with minimal boilerplate, leveraging the BEAM for fault tolerance, lightweight processes, and supervised PubSub/Presence.
Core pillars
- Controllers for JSON APIs with plugs, pipelines, and versioning.
- Contexts own data (Ecto schemas + queries) and expose a narrow API to controllers/channels.
- Channels + PubSub for fan-out real-time updates; Presence for tracking users/devices.
- Auth via plugs (session/cookie for browser, token/Bearer for APIs), with signed params.
