Streaming
Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.
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.
stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk', body: JSON.stringify(batch) ))).catch(console.error);Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.
