+## General Backend
+- Use mature, popular, regularly updated libraries. They will have the most resources available, best documentation, and issues already solved in comparison to other libraries.
+- From the get go, have a way to standardize outputting errors so its easier to consume by the front end.

+- Designing database diagram was a good idea and helped thinking through how everything worked.
+- separate controller actions from routes.
+- when writing tests, try to mock database calls to make the tests run faster.
