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.

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));

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

Streaming

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

const result = await stream.request('POST', '/transform',  data: payload ,  timeout: 5000 );

Error handling is explicit: catch failures at any stage, log them, and route bad events to a dead-letter queue without stopping the main pipeline.
