Changelog

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.

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

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

Changelog

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.

const result = await stream.request('POST', '/transform',  data: payload ,  timeout: 5000 );
