Streaming

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

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.

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

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

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

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