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

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' );

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

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.

const throttled = stream.throttle( rps: 100, burst: 200 ); const deduplicated = stream.dedup( key: 'event.id', window: 60000 );

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