Pro EP 44 : 14 Things that you Should Avoid in Controllers

These are few things that you shouldn’t do in controllers for better performance.

• Putting HTML
  - SQL statements
  - Tight Coupled code
  - Configuration settings
  - Putting a lot of if-else
  - Accessing database directly
  - Mapping classes in controller
  - Business Logics and Data Access
  - Making too many external API Calls
  - Not using caching (Not all the time)
  - Using synchronous methods everywhere
  - Making God controllers (that does a lot of things)
  - Using static methods instead of dependency injection
  - Putting exceptions in every controller (one could disagree but I will go with global exception handling)
