Master Node.js Readable, Writable, Duplex, and Transform streams with TypeScript for processing large files and real-time data without exhausting memory. For backend engineers building data pipelines and I/O-intensive services.
Your webhook processor receives 10,000 events/second. Your database can handle 500 inserts/second. Without backpressure, your queue grows unbounded, memory fills up, the process crashes, and you lose all the unprocessed events in memory.
Web Streams (WHATWG standard) are now built into Node 18+. Learn when to use ReadableStream vs node:stream, streaming LLM responses, and backpressure handling.
Master advanced streaming patterns. Learn backpressure mechanics, stream.pipeline() error handling, transform streams for CSV processing, and avoiding memory leaks in production systems.
Redis Streams offer persistence, consumer groups, and ordering without Kafka''s operational burden. Perfect for real-time activity feeds and notifications at scale.
