Events-Default Patterns

events-default supports all core BSB event patterns in-process.

Fire-And-Forget

Use for async notifications where no response is needed.

await this.events.emitEvent(obs, "service-orders", "order.created", [{ id: "o1" }]);

Returnable Events

Use for request/response between plugins.

const user = await this.events.emitEventAndReturn(
  obs,
  "service-users",
  "user.get",
  10,
  [{ id: "u1" }]
);

Broadcast

Use for fan-out events to all listeners.

await this.events.emitBroadcast(obs, "service-cache", "cache.flush", []);

Streams

Use for large payloads / continuous transfer.

const streamId = await this.events.receiveStream(obs, "service-files", "file.stream", async () => {});

Operational Notes

• In-memory only (single process/container boundary).
• No broker durability.
• Replace with distributed event plugins for multi-instance deployments.
