问题 I've got a date object in Google Sheet which I want to import to firestore as a timestamp object, but it doesn't work when I do it directly.

问题 Context: I am creating a kind-of-wiki page in Angular. The wiki page would probably not get bigger than 5000 articles in total. I want to get the most efficient (pageload) way possible but I think I am too new to this to oversee the consequences of one option over the other. Of course I also would like to follow conventions. Problem: I have a collection of articles in firestore which I want to categorize. An article should belong to one category. A category can belong to one category (as a

How can i follow the users like in Instagram so that all the followed users' posts are stored in the 'userFeed' collection?
