fx-event-bus
A simple event bus for monoliths where every node can handle any event. Designed to support loose coupling between independent parts of an application domain.
What it is
- Bus-based architecture for monolithic apps.
- Uses Postgres FOR UPDATE SKIP LOCKED for concurrent polling and exactly-once delivery.
- Provides event handlers with typed, deserialized input.
- Fully safe and statically type-checked: no unsafe code, no interior mutability.
- Handles ~2k events/sec on a single DB connection; scale horizontally by adding more servers.
What it is not
- Not a casual pub/sub library. Nodes must fully handle an event once acknowledged, or risk losing it.
- Not designed for microservices where nodes handle events differently.
