[import/default] typescript - esModuleInterop value not read correctly

[Ebooth]

The following PR was created to detect the esModuleInterop parameter in tsconfig.json. 0b585a1

It seems that the tsconfig.json file is loaded like a text file. So any extended configuration provided in the "extends" parameter of the tsconfig.json file won't be detected.

Expected:
I can set the esModuleInterop value in a tsconfig.base.json that will be extended by tsconfig.json and the rule import/default will work

Here you can find a reproduction of the bug:

Also it could be nice to add support for monorepo as the current code works only in you have one typescript project.

Hmm, I would expect tsConfigLoader to resolve "extends".

We hit this a short while ago, and I've only now gotten around to submitting a fix - sorry!
