I have made a social media app with Airtable and Firebase Auth for the user system. You can create a post with the title and content. But I am stuck at the comment function cause it is different in different posts. May anyone tell me is it possible to make a social media app with comment function in Kodular?

If your store comments in the same row/tag, it would be not better, make a different database for comments.

Thanks for your suggestion, but how to link the post with the comment?
Search on community first
To make a comment function, you need to create a node for a post and store comment inside that. See this image for reference:
Hope it helps.

MySql will be better as it’s cheaper and more powerful.

You are welcome.
You should go with real time database because Firestore is very expensive and it gives only 50k reads and writes.

Excuse me, may I ask should I save a new project bucket with all these data or save it with a list?
