relayhub

Streaming

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

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

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

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

Streaming

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 stream = new RelayKit( apiKey: process.env.API_KEY, region: 'us-east-1' );

The SDK provides both callback-based and Promise-based APIs, so you can use it with callbacks, async/await, or Observables.
