I took some time to try MeanIO over the past few days. While I ended up coming back to MeanJS, I drew some conclusions that might be helpful.
Here's the use case. I wanted to take a GeoJSON file, load it into a boilerplate MEAN stack, generate CRUD files and get a basic app tested. Ideally, I'd want to tweak the layouts, menus, and boilerplate HTML as well as use bower to add js libs that add functionality.
