StatWatcher.ref - fs - Node documentation
method StatWatcher.ref

Usage in Deno

import { type StatWatcher } from "node:fs";
StatWatcher.ref(): this

When called, requests that the Node.js event loop not exit so long as the fs.StatWatcher is active. Calling watcher.ref() multiple times will have no effect.

By default, all fs.StatWatcher objects are "ref'ed", making it normally unnecessary to call watcher.ref() unless watcher.unref() had been called previously.

Return Type
