This course will teach you all about creating a web application in the Hexagonal Architecture style. Hexagonal Architecture promotes the separation of concerns by encapsulating logic in different layers of the application. This enables a higher level of isolation, testability, and control over your business specific code. 

You will learn how to design software modules and complete applications in a clean and maintainable manner, while also learning how to advocate for a certain technique given your application and constraints.

By the end of this course, you will have a greater understanding of how to implement software architecture, a key skill for any senior developer.

Hexagonal Software Architecture for Web Applications

## The web adapter

What does a web adapter actually do? Let's say we want to provide a #key# REST: Representational State Transfer #key# #key# API: Application Programming Interface  #key# for our BuckPal application. Where do the responsibilities of the web adapter start and where do they end?

A web adapter usually does these things:
