Changelog

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

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

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

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

Changelog

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

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

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