Node.js vs Scala: What are the differences?
Node.js: A platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices; Scala: A pure-bred object-oriented language that runs on the JVM. Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
Node.js can be classified as a tool in the "Frameworks (Full Stack)" category, while Scala is grouped under "Languages".
"Npm", "Javascript" and "Great libraries" are the key factors why developers consider Node.js; whereas "Static typing", "Jvm" and "Pattern-matching" are the primary reasons why Scala is favored.
Node.js and Scala are both open source tools. Node.js with 35.5K GitHub stars and 7.78K forks on GitHub appears to be more popular than Scala with 11.8K GitHub stars and 2.75K GitHub forks.
According to the StackShare community, Node.js has a broader approval, being mentioned in 4104 company stacks & 4039 developers stacks; compared to Scala, which is listed in 437 company stacks and 324 developer stacks.
We actually initially wrote a lot of networking code in Kotlin but the complexities involved prompted us to try and compile NodeJS for Android and port over all the networking logic to Node and communicate with node over the Java Native Interface.
This turned out to be a great decision considering our battery usage fell by 40% and rate of development increased by a factor of 2.
As a small team, we wanted to pick the framework which allowed us to move quickly. There's no option better than Rails. Not having to solve the fundamentals means we can more quickly build our feature set. No other framework can beat ActiveRecord in terms of integration & ease-of use. To top it all of, there's a lot of attention paid to security in the framework, making almost everything safe-by-default.
Hey guys,
My backend set up is Prisma / GraphQL-Yoga at the moment, and I love it. It's so intuitive to learn and is really neat on the frontend too, however, there were a few gotchas when I was learning! Especially around understanding how it all pieces together (the stack). There isn't a great deal of information out there on exactly how to put into production my set up, which is a backend set up on a Digital Ocean droplet with Prisma/GraphQL Yoga in a Docker Container using Next & Apollo Client on the frontend somewhere else. It's such a niche subject, so I bet only a few hundred people have got a website with this stack in production. Anyway, I wrote a blog post to help those who might need help understanding it. Here it is, hope it helps!
