unpipe
The readable.unpipe()
method detaches a Writable
stream previously attached using the {@link pipe} method.
If the destination
is not specified, then all pipes are detached.
If the destination
is specified, but no pipe is set up for it, then the method does nothing.
import fs from 'node:fs';
const readable = getReadableStreamSomehow();
const writable = fs.createWriteStream('file.txt');
// All the data from readable goes into 'file.txt',
// but only for the first second.
readable.pipe(writable);
setTimeout(() => {
console.log('Stop writing to file.txt.');
readable.unpipe(writable);
console.log('Manually close the file stream.');
writable.end();
}, 1000);
