Answer In the context of Node.js, the term "Watcher" is often associated with modules or functionality that allows you to monitor changes to files or directories. One common u
se case is automatically triggering actions in your application when files are added, modified, or deleted. This can be particularly useful during development when you want to, for example, automatically restart your server when code files change.
There are various packages and modules in the Node.js ecosystem that provide file and directory watching capabilities. One popular module is chokidar. Chokidar is a file system watcher that can be used in Node.js to watch files, directories, or entire file systems for changes. It is built on top of the Node.js fs module and provides a simple API for handling file system events.
Here's a basic example of using chokidar to watch for changes in a directory:
In this example, the chokidar module is used to watch the specified directory for file-related events (add, change, unlink). You can customize the event handling logic based on your application's needs.
Keep in mind that other file-watching modules or techniques might also be used in the Node.js ecosystem, and the choice may depend on your specific requirements and preferences.
