Authentication tokens are rotated silently in the background; your code never handles credentials directly.

Graceful shutdown waits for in-flight events to complete, then closes connections cleanly—no lost events, no crashes.

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

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

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

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