Changelog

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

Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

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

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.

Changelog

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

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

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