Typescript forward generic type definition-CodePudding

consider this type and this generic:

type Data = { item: number };

type Generic<T> = {
  obj: T;
};

now this is an instance of it:

const test: Generic<Data> = { obj: { item: 0 } };

now what I really need when using test.obj is to see the type for obj (Data) when clicking on it, not it's type in the Generic (T)

When clicking on `test.obj`

to go to Data type definition

type Data = { item: number };

it went to its definition in the generic T

type Generic<T> = {
  obj: T;
};

so is this possible?

CodePudding user response：

If I understand the question, "simply" don't annotate your variable.

If you really must and you can use TS 4.9, use satisfies instead:

const test = { obj: { item: 0 } } satisfies Generic<Data>;
