Error handling is explicit: catch failures at any stage, log them, and route bad events to a dead-letter queue without stopping the main pipeline.

The core relayflow object is a lightweight wrapper that manages the lifecycle of your event stream.

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

The TypeScript types are fully inferred; no manual type assertions needed even with complex nested schemas.

Graceful shutdown waits for in-flight events to complete, then closes connections cleanly—no lost events, no crashes.

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);
