Advanced Web Application Architecture

Web application frameworks are indispensable. You wouldn't want to deal with raw HTTP messages yourself, nor build your own router, or ORM. But if you're not careful, a framework will take over your entire project. Business logic and framework-specific code will end up being mixed together, in controllers, services and entities. Not being able to describe the use cases of your application without also talking about HTTP, or SQL, leads to hard-to-test and hard-to-change application code. Your core code will be tied to your framework, which endangers the future of the project in the long term.

In this talk I'll explain how to make a clean separation between your own business logic and the code that makes your application's use cases available to the world outside. We'll discuss architectural concepts like "layers" and "ports & adapters", and how applying them will make your application flexible enough to deal with a constantly changing environment.
