I have setup the Lemmy backend but I can't see the backend running just only json is displaying. Lemmy ui is also setup properly but with very limited features.
See the attached screenshot of the backend.
I run "cargo run" command to start the Lemmy Backend
The lemmy backend doesn't have a UI, all it talks is JSON through APIs. That's what lemmy-ui is for, it's the UI that goes on top. It's also why the default setup overlays it on top of the backend: they're meant to work together where the UI handles browser requests, but if it's a JSON/API request then it goes to the server instead. They provide the same data in different formats on the same URLs.
Management of an instance is very limited and incorporated in the frontend.
I am not a good enough developer to make PR’s to the open source codebase, but someone reading this might be…
I think a replacement of the banned user list by a list of the users on your own instance might help a lot. Makes it easier to navigate to your users and individually manage them (with the tools already available).
However this might scale badly for large instances.
