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

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.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

Authentication tokens are rotated silently in the background; your code never handles credentials directly.

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

await stream.ack(event.id); const pipeline = stream.filter(e => e.amount > 100).map(e => ( ...e, fee: e.amount * 0.03 )).on('error', (err) => logger.error(err));
