I have covered it in previous episodes, but it was using JQuery. Thanks for the suggestion.

TIL about Object.assign, pretty neat!

I'd imagine that there will be a much more seamless way once Kamal 2.0 is released. This major update will rely on kamal-proxy (https://github.com/basecamp/kamal-proxy)  which is important for the load balancing aspects.

I like that approach too. I think that it would just depend on my application and the risk involved. By using the base controller, you're still validating that this route potentially exists. Using a constraint, the route would appear like it does not exist at all. So, I guess the best route would be whatever kind of experience you wanted for an unauthorized user.
