I agree - Rails does everything, and there isn't a JS solution that's similar out of the box. You have to be familiar with a ton of stuff not to get caught up in content marketing traps for solutions that look like they fit your use case but probably don't.
For prototyping things, I like the way Next.js generates a lot of boilerplate routing and api endpoints for you, and so in that way it's similar to rails scaffolding things for you. But when it comes to db migrations, an ORM, anything else, you're on your own!
