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 client = new querykit.Client( auth: 'Bearer token', retry: true, timeout: 30000 );

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.

The TypeScript types are fully inferred; no manual type assertions needed even with complex nested schemas.

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.
