Typescript casting object's property

Question

I\'m working with indexeddb and typescript. My issue is that TS doesn\'t seem to be able handle the event.target.result property. Case in point:

req         


        

Answer 1

You can also cast using the 'as' keyword like this

interface MyCustomUserInterface {
    _id: string;
    name: string;
}

const userID = (req.user as MyCustomUserInterface)._id
...

Cheers!
