How do i connect Ionic/Angular Admin(or any user role) panel(UI) to firestore to write collections.

Guys please need help. Building an Angular-Ionic Eccommerce App, and i need to use a backend for data storage and user management etc.
But i have some issues, i dont know to connect an admin panel/dashboard to firestore, django(python) makes that part very easy, but firestore has some cool features and its more closer to Angular than Django especially with AngularFire.

Need help with how connecting a dashboard/admin-panel or any other panel/dashboard for other user roles can be done. Any help as soon as possible will save my day. Thanks and Happy New Year tho the year is few days old
