Phoenix Api Channels

This gets you up to speed on building JSON APIs and real-time features with Phoenix on the BEAM. It covers the full stack: controllers with plugs and versioned routes, Ecto contexts for data ownership, WebSocket Channels for chat and notifications, Presence for tracking who's online, and PubSub for fan-out broadcasts. The guide is opinionated about keeping controllers thin and letting contexts own business logic, which matches idiomatic Phoenix. You'll want this when you need both REST endpoints and WebSocket bidirectionality in the same app, or when you're adding collaborative features that need fault-tolerant concurrency. It includes auth patterns, testing helpers, and telemetry setup. The coverage is practical without rehashing basic Elixir syntax.
