Warning: Cannot find parent tsconfig.json

Question

I would like to fix the warning:

Warning: Cannot find parent tsconfig.json

in the TypeScript Errors tab in Intell

Answer 1

Try setting up include section in file tsconfig.json like in below image.
(Note that my project's root folder is frontend and my include section is frontend/**/*).

Of course you don't need to rename your project's root folder to frontend.
Only the naming should match.

It should take effect immediately after you save the tsconfig.json and open a .ts or .tsx file. If it doesn't try restarting the WebStorm/IDEA.

And don't forget to clear the error console before testing this solution. It might cache the previous messages.

P/S: I'm using WebStorm 2016.3.1.

If you were using webpack together with ts-loader the above solution would cause your builds to fail. If that was the case consider this approach instead.
