Hello 🙂 I would 'namespacing' a solidus app into a subdomain like 'shop', should I do something like

mount Spree::Core::Engine, at: '/', constraints : { subdomain: 'shop' }

or

Spree::Core::Engine.routes.draw do
  constraints subdomain: 'shop' do
    ...
  end
end

?

I think it’s:

constraints subdomain: 'shop' do
    mount Spree::Core::Engine, at: '/'
end

If I’m not wrong, the latter will add new routes constrained by the subdomain, but won’t change the already defined ones. So I’d go with the first.

They are probably the same (my suggestion and the first from @Sabo)

Ok thank you for your responses I will try that 😉

Let us know if that works!

Yes 😉
