Quickstart

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

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

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

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