relayhub

Changelog

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

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

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

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

Changelog

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

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));

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