Quickstart

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

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

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

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