Changelog

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

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

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

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

Changelog

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

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));
