Additional information about the issue
This bug was signaled ~6 years ago, but was closed: #30355
The following works:
class X {
protected foo() {}
}
export function foo() {
return X;
}It produces this .d.ts :
declare class X {
protected foo(): void;
}
export declare function foo(): typeof X;
export {}So for our case, just create a temporary class outside of foo() and use it...
declare class foo__internals__X {
protected foo(): void;
}
export declare function foo(): typeof foo__internals__X;
export {}
