Web presentation patterns in Clean Architecture
Having established how Clean Architecture enables interface flexibility, we now turn to the specific patterns needed for web presentation. While our CLI directly formatted data for console output, web interfaces must handle more complex presentation requirements: formatting data for HTML templates, managing state across multiple requests, and providing user feedback through form validation and flash messages (temporary notification banners that appear at the top of the page after an action, like the green success message shown in Figure 9.1). This section explores these web-specific challenges and shows how Clean Architecture’s boundaries guide our implementation choices.
We’ll examine how web-specific presenters format domain data for HTML display, ensuring our templates receive properly structured information. We’ll see how state management across requests can respect Clean Architecture’s boundaries...
