Quickstart

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.

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

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

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

Quickstart

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

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

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