Auth

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.

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

const result = await stream.request('POST', '/transform',  data: payload ,  timeout: 5000 );

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

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 querycore.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.
