Changelog

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

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); );

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

Changelog

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.

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

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