Backpressure and Piping

Manage flow control with pipeTo and pipeThrough.

The Backpressure Problem

If a producer generates data faster than a consumer can handle, memory fills up. Backpressure is the mechanism by which a slow consumer tells a fast producer to slow down.

WritableStream

A WritableStream is a destination you write chunks into. Its write(chunk) sink method may be async, signaling readiness for the next chunk.

const sink = new WritableStream({
  write(chunk) {
    console.log("writing", chunk);
  }
});
