Architecture

There are usually three main layers:

• Route (or Controller)
• Service
• Model

Route / Controller Layer

• Purpose: Handles HTTP requests and responses, Calls the service layer for processing, Returns validated responses

Service Layer

• Purpose: Encapsulates business logic
• The service layer sits between routes and models.
• Handles things like: Complex Validations, Checking permissions or ownership

Model Layer

• Responsible for defining data structures and interacting with the db (queries)
