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

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

const batch = stream.pipe(filter((e) => e.type === 'payment'), batch(100), debounce(5000));

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

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

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