It's lovely to see a sane backend language being used instead of shitty Javascript.
Personally I do prefer Rails over something like Express too, but that's more of a personal preference. I don't see why todays Javascript backends are all "shit"?
Seriously though, the language itself is a matter of preference, but you can’t dismiss that the ecosystem sucks. Projects with hundreds of packages in their dependency graph seem common. I’ve worked on a (front-end) React project with 1,7k packages involved in the build process. That’s madness.
