Ask HN: How is your JavaScript based backend organized?

I come from a Ruby on Rails background. It is great - working with Rails has had two huge upsides for me. First, the framework means there is a good way to do almost everything. Two, it makes me think about problems and the solutions generally fit elegantly into the framework. Now, I'm sure there are Rails like frameworks for full-stack Javascript development. I'd love to hear about how you organize things like: - Data migrations. - Deployments. - ORM - Background tasks. - APIs - Multiple language support in front-end templates. etc..etc.. Do most people roll their own back-kend framework? As an aside, whats the state of server-side template rendering? Is that industry practice?
