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

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

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

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

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);
