When opening a file using fs.createWriteStream, how do you handle the case where the underlying file is deleted (eg by a 3rd party, such as logrotate)?
None of the normal events seem to fire in this case.
For example:
const stream = fs.createWriteStream(filename, { flags: 'a' });
// None of these seem to fire
stream.on('close', () => console.log('CLOSED'));
stream.on('error', () => console.log('ERRORED'));
stream.on('finish', () => console.log('FINISHED'));
stream.write('foo');
// wait for flush...
fs.unlinkSync(filename);
// This doesn't work, but also doesn't error
stream.write('bar');

Notes:
- Node v12.10.0 added the
emitCloseoption, which presumably fixes this(?), but I'd like to do this in v10 (LTS)
