Play vs Yesod: What are the differences?
What is Play? The High Velocity Web Framework For Java and Scala. Play Framework makes it easy to build web applications with Java & Scala. Play is based on a lightweight, stateless, web-friendly architecture. Built on Akka, Play provides predictable and minimal resource consumption (CPU, memory, threads) for highly-scalable applications.
What is Yesod? A RESTful Haskell web framework built on WAI. Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference.
Play and Yesod can be categorized as "Frameworks (Full Stack)" tools.
"Scala" is the primary reason why developers consider Play over the competitors, whereas "Haskell" was stated as the key factor in picking Yesod.
Play and Yesod are both open source tools. Play with 11.2K GitHub stars and 3.77K forks on GitHub appears to be more popular than Yesod with 2.11K GitHub stars and 329 GitHub forks.
Coursera, Zalando, and Keen are some of the popular companies that use Play, whereas Yesod is used by FP Complete, DoxIQ, and SimplyRETS. Play has a broader approval, being mentioned in 112 company stacks & 47 developers stacks; compared to Yesod, which is listed in 5 company stacks and 5 developer stacks.
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
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.
If you are comfortable with TypeScript, why not evolve to a C# ecosystem? Asp.Net Core + Entity Framework is a mature and well supported technology. As far as I can see in the enterprise market, the most adopted choice is still Java. So, maybe you may have a look to SpringBoot - and ultimately Quarkus.
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.
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.
