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

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

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

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

Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

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

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