Introducing RIG – the Reactive Interaction Gateway
summary
RIG is a stateful gateway that holds frontend connections, consumes Kafka topics and routes events to connected devices across a cluster, enabling instant logout via a JWT blacklist and tearing down connections on blacklist propagation. It uses Phoenix Presence as an in-memory CRDT presence to track which user devices live on which node, exposes WebSocket, Server-Sent Events and long-poll fallbacks, requires no external database, is written in Elixir on Erlang/OTP, and reached a 1.0 feature set in under 600 lines of code.
