Auth

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

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

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.

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

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