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

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

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