It's not magic per se. I will caveat that I never liked the way Rails does MVC, so I've always used Rails as logic source (api and SaaS "brain"). I abhor Rails View approach, as it's kludgey and requires a Rails team to make front end changes. But having a common language (js) works for me. And scaling Rails while is much more work (and I think requires a bigger team) than with Sails JS (which I use). Development seems faster (no measurements - just a feeling). Granted Sails built ins make the difference on moving faster in node.
