I have something similar to this I'm trying to find a better way without making manual interfaces below.

type Type = 'a' | 'b'

interface Block<T extends Type> {
  content: typeof someObject[T]['childObj']
  type: T
}

interface AType extends Block<'a'> {}

interface BType extends Block<'b'> {}

Here's a much more accurate example of what I'm trying to do if anybody could help. Ignore the syntax warning, i just did a quick repro, in my code the error doesn't exist

i removed aliases like AudioBlockType as you could instead use BlockType<'audio'> (and not having it means you only need to mention each type in one place, which might help with maintainability)

#

but such aliases could easily be reintroduced if they pull their weight

Wow, I'm pretty sure that's exactly what i was looking for. You're the best
