What is the purpose of the `unpipe()` method in Node.js streams, and how does it work?

Difficulty: 5/10

stream lifecycle, error handling, backpressure

The unpipe() method in Node.js streams is used to detach a writable stream from a readable stream. This essentially stops the flow of data from the readable stream into the writable stream, undoing the connection that was established using .pipe()

Purpose of unpipe()

1
Stop Data Flow: It halts the automatic data transfer between streams that were connected via .pipe()
2
Fine-Grained Control: If multiple writable streams are piped from a single readable stream, unpipe() can be used to detach a specific writable stream without affecting the others
3
Prevent Memory Leaks or Errors: It ensures no unnecessary data transfer continues, especially if a writable stream is no longer valid or needs to be closed.

javascript

1
If you pipe a stream to multiple destinations, with a specified stream will detach only that destination.
2
Using unpipe() without arguments stops all piping to writable streams.
3
unpipe event is emitted by the readable stream whenever a pipe is undone. You can add a listener for it:
