Struct AdminCheckWrapper 

pub(crate) struct AdminCheckWrapper {
    pub(crate) _marker: PhantomData<()>,
    pub(crate) function_component: FunctionComponent<Self>,
}

Wrapper component that checks if an admin exists before rendering children.

This component is used to gate access to pages that should only be accessible before system initialization (e.g., login page). It performs an asynchronous check to the backend’s /api/check-admin endpoint (via crate::handlers::auth::check_admin_exists) to determine system state.

Behavior

• Loading: Displays “Loading…” while checking admin status from the backend
• No Admin: Automatically redirects to Route::Setup page for initialization
• Admin Exists: Renders the wrapped children (e.g., login page)

Example Usage

<AdminCheckWrapper>
    <LoginPage />
</AdminCheckWrapper>

Backend Integration

The check queries the backend’s /api/check-admin endpoint which returns {"has_admin": bool}. This allows the frontend to determine if initial admin setup is required.

Fields

_marker: PhantomData<()>

function_component: FunctionComponent<Self>
