javascript - Can I use Typescript intellisense in a JS project for custom modules?

Question

I'm working in a JS code base but I wanted to add declarations for some complex entities in the application. This is so I have them as auto-completable in my VS Code.

This works for dependencies that have TS declarations so I presume it can be done.

I tried the following in a d.ts file beside my .js file`

import "./useUserContext";

declare module "./useUserContext" {
  interface User {
    user: {
      uid: string;
    },
  }

  export default function useUserContext(): User;
}

There is sadly no possibility of converting this project to TS.
