Backend Architecture

We will be using express as the main framework and tsoa as a framework to abstract away some manual processes such as:

• Route creation (All done in controllers)
• Authentication middleware
• Request validation
• Documentation (Done through annotations)

This means that for the backend we will need to focus on writing:

response-models: Typescript interfaces which describe what response data will be returned

request-models: Typescript interfaces which describe what data is expected in the request

models of DTOs: Typescript interfaces which describe the shape of data

services: Typescript classes which perform operations that are consumed by controllers

controllers: Typescript classes annotated using tsoa to describe the behavior of routes
