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

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

const client = new relayhub.Client( auth: 'Bearer token', retry: true, timeout: 30000 );

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

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

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

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