I'm using webstorm for node.js development but the core modules are not in the JS library

I'm trying to require modules such as http and fs but these module are missing. Actually, require() itself is not recognized by my webstorm.

What's causing this? How can I get the core modules?

attached is a screenshot of my JavaScript libraries:

p.s. my software is 100% legit (I have a valid license etc.)
