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.

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

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

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

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