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

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.

stream.on('*.created', async (event) =>  await db.insert('events', event); ,  concurrency: 50 );

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

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

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