Streaming

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

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

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

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

Streaming

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

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

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