npm install @types/node --save-dev

Then in tsconfig.json, include

Ok, Here I have seen a lot of answers already given, I want to add some more that are fixed unresolved function/method/variable warning.

That is resolved "unresolved function or method for 'require' and some other warning"

Go -> Preferences-> Languages & Frameworks -> Node.js and NPM, then checkmark the "Coding assistance for Node.js"

If you still see this type of warning, unresolved variable or something like that, you can manually disable these warnings by followings.

Go -> Preferences-> Editor-> Inspections-> JavaScript-> General.
