querycore

Client

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

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

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));

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

Client

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);
