Phalcon vs Play

In the past few months, a project we're working on grew up quite fast. Since we're adding more and more features, I'm considering migrating my Express/TS REST API towards a more solid and more "enterprise-like" framework. Since I am experienced with TypeScript but not so much with Rails nor Play (Scala), I'd like to have some advice on which one could provide the best development experience, and most importantly, the smoothest paradigm transition from the JS/TS world. I've worked on some personal project with Rails, but I've found the Ruby language really distant from what the TypeScript ecosystem and syntax are, whereas on the opposite - during the brief tours I've taken in the past weeks - it's been a pleasure coding in Scala. Obviously, there are some key differences between the two languages - and the two frameworks consequently - but despite all the ROR automation and ease of use I don't despise at all Scala's pragmatic and great features such as static typing, pattern matching, and type inference. So... Please help me out with the choice! Regards

If software performance is your top priority, then Scala/Play is probably best. If developer productivity is your top priority, then Ruby on Rails is the best choice in my opinion.

The Rails framework is batteries-included. The framework takes care of many things by default so that you don't have to. Logging, security, etc. It's also well-integrated; for example, controllers understand models out of the box. I had a better experience with RoR than with Play.

On the other hand, Scala and the JVM are more performant in general, so they can scale to serve more requests per second on the same hardware.

If you're considering serverless functions, then Scala is probably a better choice because it would be faster to load, giving you better economics.
