Find Unused npm Packages in Your Package.json

JavaScript makes it easy to install packages and dependencies into our apps.

The problem is, after a few days, weeks, or months of hacking, how the heck do we know what isn't even being used anymore?

Find unused packages

It's easy with a neat package called depcheck.

From your terminal, go into the root folder of your project (wherever your package.json lives) and run the following command:

npx depcheck

Now you'll see the output showing two sections, your "unused depencies", and "unused devDependencies".

Now, uninstall those suckers!!!

Although it's usually great, I've noticed occasionally depcheck gets it wrong, so make sure you confirm that you aren't using those packages before you drop the dynamite. 💣
