Quickstart

The SDK provides both callback-based and Promise-based APIs, so you can use it with callbacks, async/await, or Observables.

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

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

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.

Quickstart

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

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

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