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

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); );

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.

Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

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

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