Client

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

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

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

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

Client

Error handling is explicit: catch failures at any stage, log them, and route bad events to a dead-letter queue without stopping the main pipeline.

const client = new wavehub.Client( auth: 'Bearer token', retry: true, timeout: 30000 );

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