Reference

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

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

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));

Authentication tokens are rotated silently in the background; your code never handles credentials directly.

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

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