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

The SDK provides both callback-based and Promise-based APIs, so you can use it with callbacks, async/await, or Observables.

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.

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

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

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