I would guess commodity plumbing like hooking up the front end alongside a data store in the backend, and other stuff like auth. There's a lot of work you have to do to get something like express on par with Rails or any other Rails inspired framework for which there are many in multiple languages even in the JS/TS world. imo the one I like best in nodejs is Blitzjs https://blitzjs.com/ https://blitzjs.com/ FoalTS https://foalts.org/ https://foalts.org/ is nice too and there are several other full stack frameworks like Nestjs, FeatherJs, and redwoodjs
