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.

stream.on('*.created', async (event) =>  await db.insert('events', event); ,  concurrency: 50 );

Metrics are published to standard formats (Prometheus, CloudWatch, DataDog) with zero configuration.

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

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