ruby and rails is a much nicer, more complete, more consistent, and easier to learn ecosystem relative to js/node. and node is just the js server, so you need need a framework on top of it, like react/angular/vue/ember, to be equivalent. for most use cases, i really can't recommend the js-heavy route now that rails comes with hotwire (a transparent js framework for live/async html transfer, rather than json). for authentication/authorization/security, it's great to learn by writing those from scratch, but unless you want that to be your career focus, you'd really be much better off to defer to battle-hardened libraries in those areas for any commercially-/publicly-oriented web app.
