Quickstart

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' );

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

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

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