I'm building an app which essentially needs to be a 'shell' that sends a user to a different 'mini' app based on their user profile. Each 'mini' app should be silo'd from the others and users should be blocked from manually entering a URL for an app they don't have access to.
Wireframe layout of each app is the same (top navbar, sidebar, main content etc) but the content of each of those components will change based on which app they're in and will be fed in from a config file from a DB.

What's the best way to go about this?
