Auth

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

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.

Auth

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

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

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