Hexagonal Software Architecture for Web Applications

Dependency Inversion with a Web Adapter

Explore how to implement a web adapter that uses the Dependency Inversion Principle in Hexagonal Architecture. Understand the communication between the web adapter, application core, and ports to create clean, modular, and maintainable web interfaces for HTTP and real-time data.

We'll cover the following...

Introduction

Most applications today have some kind of web interface — either a UIUser Interface that we can interact with via web browser or an HTTPHypertext Transfer Protocol APIApplication Programming Interface that other systems can call to interact with our application.
