I want to built a new feature for my REST application and don't really know how or where to start. The user should be able to access data in diffrent databases. Should I implement a kind of session managment which saves the name of the database. So I only change the connection when the user wants data from a diffrent database or should I implent it inside the URI like /api/database/.../... ? At the moment I'm working with a Micro setup + collections.
