method FSWatcher.ref
Usage in Deno
import { type FSWatcher } from "node:fs";
FSWatcher.ref(): this
When called, requests that the Node.js event loop not exit so long as the fs.FSWatcher is active. Calling watcher.ref() multiple times will have
no effect.
By default, all fs.FSWatcher objects are "ref'ed", making it normally
unnecessary to call watcher.ref() unless watcher.unref() had been
called previously.
