Angular app with firebase auth and node.js / mongodb : <p>I am just planning architecture for my web app and I just wanted to ask you, if it is good idea to use Firebase auth with Angular and mongoDB as a database. (I don't want to use Firestore realtime database)</p>

<p>Is a good idea to use queries directly from my Angular client or do I need some node.js/express backend for this? What would be the best solution?</p>

<p>Thanks for your advices.</p>
