How to use require and first together?

[renatoargh]

I have the case where I have two defaults, if none of them are present I want an exception to happen, for example:

// this is just an example with imaginary code (from the tests I know it does work)
const project = env.require(['FIRST_ENV', 'SECOND_ENV'])

The project variable, in this case, would also benefit because it could be typed as a string and not as a string | undefined as when I use just .require

By the way, great work! Congrats :)

That's not currently supported. I think you're looking for something like a requireFirst() method?

[renatoargh]

Yeah, that name makes sense! I had the same idea :)

I think it is important to make sure that the type returned is T and not T | undefined so that we don't have to perform any checks afterward (since it is either there or an exception was thrown)

Thanks for the quick reply

That's a good point. I'm open to adding a new method, I just need to think through the naming and function signature a bit.
