# Dependency Injection

Use dependencies when:

* They can't be declared in Pydantic validation and require additional logic
* The logic depends on external resources or could block in any other way
* Other dependencies need their results (it's a sub-dependency)
* The logic can be shared by multiple endpoints to do things like error early, authentication, etc.
* They need to handle cleanup (e.g., DB sessions, file handles), using dependencies with `yield`

   4. Following on from the above point, please add docs to existing public
      methods if you are editing them, or to abstract methods if you can.
   5. Non-public, non-abstract methods don't require Javadoc, but if you feel
      that adding some would make it easier for other developers to
      understand the code, or why it's written in a particular way, then please
      do so.
