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

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

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

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

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.

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

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