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.

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

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

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

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

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

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