Function watch

  • Watch for changes on filename, where filename is either a file or a directory.

    The second argument is optional. If options is provided as a string, it specifies the encoding. Otherwise options should be passed as an object.

    The listener callback gets two arguments (eventType, filename). eventTypeis either 'rename' or 'change', and filename is the name of the file which triggered the event.

    On most platforms, 'rename' is emitted whenever a filename appears or disappears in the directory.

    The listener callback is attached to the 'change' event fired by fs.FSWatcher, but it is not the same thing as the 'change' value ofeventType.

    If a signal is passed, aborting the corresponding AbortController will close the returned fs.FSWatcher.
