Node.js Streams: Advanced
Handle backpressure, use stream.pipeline() safely, implement Transform streams, tune highWaterMark, and work in object mode.
readable.pipe(writable) handles backpressure automatically — when writable.write() returns false, pipe pauses the readable and resumes it on the drain event. Without backpressure handling, a fast file read piped to a slow network write would buffer the entire file in memory, potentially causing OOM.Frequently Asked Questions
