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

Authentication tokens are rotated silently in the background; your code never handles credentials directly.

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

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

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

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

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