Building Microservices API in Go - Implementing Hexagonal Architecture

The video tutorial explains the hexagonal architecture, emphasizing its role in separating code into user, domain, and server sides. It highlights the benefits of decoupling code from external implementations, enhancing maintainability and testing. The tutorial guides structuring an application using this architecture, starting with defining business objects and secondary ports, followed by creating adapters and stubs. It covers implementing services, connecting primary and secondary ports, and wiring the application. The video concludes with a recap and a preview of writing a MySQL database adapter.
