How to get the type of a signal store ?

[alcaidio]

I would like to have the type of my store to use it in a app initializer.

for example i have

export const UserStore = signalStore(
  { providedIn: 'root' },
  withDevtools('user'),
  withState(initialUserState),
  withMethods(store => {
  ...
  })
)

Typescript infer the type with something like :

UserStore: Type<{
    profile: DeepSignal<KeycloakProfile>;
    isLoggedIn: Signal<boolean>;
    loadUser: (payload: {
        profile: KeycloakProfile;
        roles: Role[];
    }) => Promise<...>;
} & StateSignal<...>>

But i would like something more condensed to it here for instance :

const initializeUser = () => ({
  provide: APP_INITIALIZER,
  useFactory: (store: STORE_TYPE_HERE),
  multi: true,
  deps: [UserStore],
});

Anybody have some ideas to do it ? I try with ReturType<typeof UserStore> but it's not works...

Workaround, i create

interface PartialUserState {
  loadUser: (payload: {
    profile: KeycloakProfile;
    roles: Role[];
  }) => Promise<void>;
}

Because i only need to use loadUser in my intializer.

But this not resolve my question...
