How examples/server-complete implements swaggerUI?

[Icarus9913]

Hello! I checked examples/tutorials/todo-list/server-complete source codes and did not find api property useSwaggerUI set to be true or method func (o *TodoListAPI) UseSwaggerUI() is called. But I still can visit swaggerUI with route /docs. How does it possible? Is there any flags did it which I ignored?

Environment

swagger version: 42c184c
OS: darwin

The UseSwaggerUI is a toggle between a redoc docs site and a swagger ui docs site.

go-swagger/examples/tutorials/todo-list/server-complete/restapi/operations/todo_list_api.go

Lines 123 to 131 in 922497f

	// UseRedoc for documentation at /docs
	func (o *TodoListAPI) UseRedoc() {
	o.useSwaggerUI = false
	}
	// UseSwaggerUI for documentation at /docs
	func (o *TodoListAPI) UseSwaggerUI() {
	o.useSwaggerUI = true
	}

if you want to disable /docs you can use a global middleware that returns not found for the /docs path.

Copied by @casualjim :
A server project built by go-swagger owns the capability to provide a UI. And the property 'useSwaggerUI' is a toggle between a redoc docs site and a swagger ui docs site, which could be thought as a UI theme.

The UI is very small, it's a single js you include in a basic html5 page. All the capability provided by 'go-openapi' project.
