API

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

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

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.

API

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

stream.on('*.created', async (event) =>  await db.insert('events', event); ,  concurrency: 50 );
