Just Google it. https://reactnative.dev/docs/typescript

I was following that guide and got stuck here, running into errors ... That's why I was checking if this is still up to date. Also do I need everything in this file? Jest?

Can anyone explain how this sits into Metro? I want to see my type / lint errors inside the metro terminal, just like how expo does it.
