Avoid expanding typed map keys

[hirunatan]

Hello. I don't know if it's possible, but I ask just in case.

I have a class property that is a map, and the keys must be part of a fixed list of keywords:

class MyClass {
  ...
  appliedProps: { [property in AllProps]: string };
  ...
}

type AllProps = "prop1" | "prop2" | "prop3" ...

When I use TypeDoc it expands it to show all properties in the HTML page:

class MyClass {
  ...
  appliedProps: {
    "prop1": string,
    "prop2": string,
    "prop3": string,
    ...
  };
  ...
}

I find it to be excesively verbose. Would it be some way of telling TypeDoc not expand values and just display appliedProps: { [property in AllProps]: string }?

Because you've written the mapped type inline, by the time TypeDoc gets the type TypeScript has already expanded it into an object type. If you declared it as Record<AllProps, string>, TypeDoc would document it as that.

A feature request for a @useTypeNode, which would behave kind of like the inverse of @useDeclaredType seems potentially reasonable. (Though what does that mean for functions, there's more than one type there... and they are special)
