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
This is advice regardless of your background and requirements. The Play framework has a terrible and complicated design, don't risk it. I even suggest Spring and Kotlin over it! You can use Scala for small services and Data Engineering stuff and benefit optimizations and threading of JVM. RoR, on the other hand, has a huge development speed, which I believe is a big advantage cause you can handle performance bottlenecks later. Also, Scala has another downside, which is featureful in terms of OO and FP paradigms, which makes anyone write code freely with any personal style and makes it a problem in a team, Hence a coding style has to be defined if there would be Scala development team.
I don't have the Scala experience to compare the two, but I can say that Ruby is a wonderful language. For procedural programming where you don't need a lot of concurrent execution threads, it's superior to Node.JS in my opinion. All of the concepts from Typescript have equivalent syntax in Ruby, but there are fewer symbols (e.g. () => { ... }); ) and more keywords (eg 'do ... end'). It's a very flexible language and allows for a lot of different approaches to how it's written, so coding standards and careful organization is important. In the long run, however, you'll find it quicker to debug than Node.JS and just as powerful.
