Reference

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

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

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.

Reference

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.
