generate ts types with type keyword instead of interface

[kkharji]

Hello,

It came to my attention while trying to use an awesome library for forms that interface might have some limitation for developers using typescript advance type system.

It would be awesome if there is an option to generate with type keyword instead of interface keyword.

Thanks

We're going to go ahead with this change in Specta, since the only real advantages provided by interfaces are declaration merging and compatibility with classes, neither of which are of concern to Specta or rspc.

Great to hear. Thanks @Brendonovich

Sorry, completely forgot to reply.

It makes sense to go ahead with the change to types. I have had enough people who know way more Typescript than me, agree making this change is fine. For reference this recent video by Matt Pocock brings up what is essentially the problem we have here.
