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

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

const stream = new RelayKit( apiKey: process.env.API_KEY, region: 'us-east-1' );

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

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

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