Question about how to manage multiple user interface

[Blackleones]

I've come here from your presentation of "Vertical Slice Architecture" at NDC Sydney.

I've noticed that all the codes strictly related to accomplishing a specific request are in the same folder/file.

For example all the code related to Create student is into Create.cshtml.cs file, that contains:

• user interface specification,
• command model,
• command validator,
• command handler,
• command mapper to an entity.

I was wondering about "What about if I want to create a WebApi/Blazor/(another user interface) entry point with the same request? Do I have to 'copy and paste' the code inside the Create.cshtml.cs file or can I take out this logic and create a common endpoint?"

In that case, you'd handle the duplication as you would anything else inside handlers. You don't want to re-use requests and handlers, though. There might be subtle differences that you can't predict between an API and Razor Page.
