Quickstart

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.

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

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

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

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

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