For context, Im used to working in MVC with .net core for webdev, which has everything all nicely contained within VS for better or worse. I believe Lemmy uses react.js and rust from a cursory glance, but im not quite sure what exactly is best. Im also curious what db software it would use

Im also curious on how a testing environment would work for this. I imagine youd have to host your own instance to test any changes to have access to data, but theres a lot here that honestly I dont know much about.

Is there any posts or documentation anywhere that would be a good guide to getting started on this sort of thing? I doubt development is going to be as seamless as developing in Visual Studio where everything is all from the same company, but Id imagine that there are particular ides that work better with the types of tools that manage this
