Attempted to apply MongoDB and use it to generate "calendar rooms" (corresponding to URLs) so that URL distribution would be easy for calendars.
I did everything.
I learned how to use Mongo - I'm actually accustomed generally to using Ruby databases, so this was a necessary intervention for me. In addition, I further developed ideas for how data storage per user per calendar is going to work, having been studying the data structure of Mongo databases.
Nothing. Everything worked smoothly; admittedly, I spent more time than necessary struggling to get the command structure down for Mongo, and even now am uncertain about my ability to formulate queries correctly. But I think the basic concepts are there.
I followed and made modifications on the MongoDB React Tutorial.
