I created a super advanced To-Do App using express & bootstrap (as there was no example with express). It uses Auth for registering / login, you can have personal aswell as todo lists shared with teams, a Team Admin Panel, etc. Is this maybe something that could be added as an advanced example (RLS is added to every table used). I currently only translated it to german but if you want to play around with it a bit, you could visit http://todo.f0rce.de If this would be considered as example I would obviously rewrite most of the code to be readable by english speaking people and add realtime to the teams part. I would really love contributing to such a nice project.
