Netty vs Scala: What are the differences?
Developers describe Netty as "Asynchronous event-driven network application framework". Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server. On the other hand, Scala is detailed as "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.
Netty belongs to "Concurrency Frameworks" category of the tech stack, while Scala can be primarily classified under "Languages".
"High Performance" is the top reason why over 2 developers like Netty, while over 177 developers mention "Static typing" as the leading cause for choosing Scala.
Netty and Scala are both open source tools. It seems that Netty with 19.9K GitHub stars and 9.05K forks on GitHub has more adoption than Scala with 11.8K GitHub stars and 2.75K GitHub forks.
Twitter, Coursera, and 9GAG are some of the popular companies that use Scala, whereas Netty is used by Outbrain, Appian, and Rapido. Scala has a broader approval, being mentioned in 437 company stacks & 324 developers stacks; compared to Netty, which is listed in 11 company stacks and 14 developer stacks.
