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

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

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.

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.

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