API

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

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

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.

Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.

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.
