Hello,

when importing an object from a file located at @/lib/{file.ts} on the App Router (Next.js 15.1.6, dev environment, turbopack), the changes to the object are not synced across all imports, i.e. if I add something to the object it is not reflected in other files.

Let's say the files are somewhat like this:
@/lib/{file.ts}

  const users: { [index: string]: User } = {};

  async function loginUser(username: string, password: string) {
    const user = new User(username, password);
    const loginStatus = await user.login();
  
    if (loginStatus) {
      users[username] = user;
    }
  
    return loginStatus;
  }

after calling the loginUser function from API Route /login, the new user is not shown in i.e. API Route /menu
(console.log returns {}) as if it was freshly initiated

Honestly I do not know if this is intended behavior or not, but I would like some clarification and solutions if possible 😁

Using a database is not suitable for me, but I really wanna use API Routes (import has to sync).

Thanks!
