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

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 stream = new RelayKit( apiKey: process.env.API_KEY, region: 'us-east-1' );

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

Auth

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.

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

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