Quickstart

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

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

stream.on('*.created', async (event) =>  await db.insert('events', event); ,  concurrency: 50 );

Graceful shutdown waits for in-flight events to complete, then closes connections cleanly—no lost events, no crashes.

Quickstart

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.

stream.pipe(retry( maxAttempts: 3, backoff: 'exponential' ), timeout(30000)).subscribe(console.log);

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