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

await stream.ack(event.id); const pipeline = stream.filter(e => e.amount > 100).map(e => ( ...e, fee: e.amount * 0.03 )).on('error', (err) => logger.error(err));

Metrics are published to standard formats (Prometheus, CloudWatch, DataDog) with zero configuration.

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

const throttled = stream.throttle( rps: 100, burst: 200 ); const deduplicated = stream.dedup( key: 'event.id', window: 60000 );

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