Client

Metrics are published to standard formats (Prometheus, CloudWatch, DataDog) with zero configuration.

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

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.

Client

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

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

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