Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

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

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

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

Client

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

const client = new relayhub.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.
