Is there a slim3 skeleton project that offers a basic admin app (database) with very little UI?
I have tried these two but they seem to have alot of extra functionality
Try this one https://www.adminer.org/.
But, I think, it’s not Slim PHP-based.
All in all, in your project you can use Slim PHP and Adminer for concrete purposes.
adminer is a phpmyadmin alternative. I am not sure why it is related to my question
As I see you need simple admin-app for your Database. Those GithHub-projects, you mentioned, are good and they have their own nuances and complexity. Should you reinvent the wheel to just perform CRUD operations via simple UI? Just use Adminer (it’s only one PHP-file, it has very simple UI).
If the Adminer does not suit for your case, then, of cause, custom Slim-app will be better.
I don’t clearly understand what kind of admin are you looking for, because most of skeleton are without it, just scaffolding components to give a starting point for your custom code needs.
Anyway you should take a look on https://github.com/HavenShen/slim-born and https://github.com/rotexsoft/slim3-skeleton-mvc-app
