querycore

Quickstart

Metrics are published to standard formats (Prometheus, CloudWatch, DataDog) with zero configuration.

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

await stream.on('user.created', async (event) =>  console.log(event.data.email); );

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

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));

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