🕗 Version & Regression Information

This is a regression from prior versions. You need two packages to reproduce so you can repro here: https://github.com/ericanderson/ts55-beta-regression

Simply changing from 5.4 to 5.5-beta causes typeof references to no longer produce proper/compatible .d.ts files.

💻 Code

dep/src/index.ts:

interface Shape<T extends string> {
    hmm: T
}

const _Holder = {
    hmm: "foo"
} satisfies Shape<"foo">;

type _Holder = typeof _Holder;
export interface Holder extends _Holder { }
export const Holder = _Holder as Holder;

main/src/index.ts:

import { Holder } from "dep";
Holder.hmm;

🙁 Actual behavior

src/index.ts:3:8 - error TS2339: Property 'hmm' does not exist on type 'Holder'.

3 Holder.hmm;
         ~~~

dep/lib/index.d.ts

declare const _Holder: typeof _Holder;
type _Holder = typeof _Holder;
export interface Holder extends _Holder {
}
export declare const Holder: Holder;
export {};

🙂 Expected behavior

No errors.

dep/lib/index.d.ts:

declare const _Holder: {
    hmm: "foo";
};
type _Holder = typeof _Holder;
export interface Holder extends _Holder {
}
export declare const Holder: Holder;
export {};
