How does fs-extra.watch work?

fs-extra.watch is a method provided by the fs-extra library for watching files or directories for changes on the file system. It creates a fs.FSWatcher instance internally and provides a set of event listeners for handling file system events. The fs.FSWatcher instance is returned, which can be used to stop watching the file or directory when required.

const fs = require("fs-extra");

const watcher = fs.watch("/path/to/directory");

watcher.on("change", (eventType, filename) => {
  console.log(`Event type: ${eventType}`);
  console.log(`Filename: ${filename}`);
});

This example sets up a watcher on the specified directory and logs any changes that occur in that directory.
