The following are the major advantages of Play/Scala stack to develop web applications:
1.Open Source-Play is an Open-source free-software framework to develop web applications.
2.Better Productivity-Play framework’s Auto-reload feature improves Developer Productivity. No need to build, deploy and test our changes. Just do our changes and refresh the page to see our changes.
3.Stateless and Easy to Develop REST API-Play is HTTP based stateless model to serve web requests so it is very easy to develop REST API or RESTful Web Services.
4.Better Error-Handling-If we develop our web application using Play framework,it informs all errors in the browser in very useful format. It shows error message, the file location, line number where error occurred, highlighting the code-snippet to understand the error very easily.
5.High Performance and Better Scalability With Reactive-Play framework is developed by following Reactive design patterns and it is built on top of Netty sever to utilize Non-blocking IO Feature. Because of this feature, we can develop very highly Scalable and performance applications very easily.
6.Easy to Extend-Play is very flexible framework and supports developing plug-ins very easy to extend it’s features and functionality.
7.Highly Concurrency and Better Parallelism-As both Scala and Play supports Functional Programming, it is very easy to develop Highly Concurrency and Better Parallelism applications very easily because FP supports Immutability, Pure Functions (Functions without side-effects), Pattern Matching, Actor Model etc.
8.Better Reusability, Easy to Test and More Modular-As both Scala and Play supports Functional Programming, we can develop more modular and reusable applications. It is also very easy to test more modular applications.
