API

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

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

const throttled = stream.throttle( rps: 100, burst: 200 ); const deduplicated = stream.dedup( key: 'event.id', window: 60000 );

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

API

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

await stream.ack(event.id); const pipeline = stream.filter(e => e.amount > 100).map(e => ( ...e, fee: e.amount * 0.03 )).on('error', (err) => logger.error(err));
