Top 10 Scala and Groovy Frameworks Java Developers can learn in 2020

Hello guys, Groovy and Scala have been around for some time and there is some useful Groovy and Scala framework out there that can help Java developers to create better applications and products like Microservices et all. If you are interested in learning the best Scala and Groovy framework then you have come to the right place. In the past, I have shared the best courses to learn Scala and Groovy and In this article, we are going to take a look at some of the best Scala and Groovy frameworks that can be useful in Java development  Akka, Lagom, Play, Spock, Gradle, and Grails. I'll also share links to some useful courses you can learn these useful Groovy frameworks.

We'll first see the best Scala frameworks which can also be useful for Java developers like Play, Akka, and Spark. These frameworks will give you some choices and knowledge about deciding which technology and framework are better for your requirement.

After that, we'll see useful Groovy frameworks like Grails for web development, Gradle for build and dependency management, and Spock framework for automation and unit testing.

But, the story doesn't end there as we will again look at some more new and advanced Scala frameworks like Lagom for creating Micorserices, Lift for creating web applications, and Monix, a high-performance Scala / Scala. js library for composing asynchronous, event-based Scala applications.

By the way, if you re new to Scala then I highly recommend you to first go through Scala and Functional Programming for Beginners | Rock the JVM  course by Daniel on Udemy. This 15 hour 30 minutes online course is the best course to learn Scala online and teach you all the essential Scala concepts needed to uses these frameworks.




10 Best Groovy and Scala Frameworks Java Developer can Learn

Without wasting any more of your time, here is a list of best Scala and Groovy Framework which Java developer can learn to write better applications using Java, Groovy, and Scala. Along with what are these framework and what benefits they provide, I have also mentioned relevant courses which you can use to learn these frameworks, tools, and libraries.


1. Akka Concurrency Framework

There is no doubt that writing correct distributed, concurrent, fault-tolerant, and scalable applications are difficult in Java. Akka aims to solve this problem by introducing the correct level of Abstraction and using the best tools and practices. Akka introduces Actor modern and provides a better platform to build scalable, resilient, and responsive applications.

It provides a complete toolkit for building highly concurrent, distributed, and resilient message-driven applications in Java and Scala. I

f you want to improve your concurrency skills then learning Akka can be a great idea and if you need a resource then you can use this Akka Essentials with Scala course by Daniel CioCirlan from Udemy. It's one of the best course to learn the Akka actor model with Scala and write parallel, concurrent and fault-tolerant systems.

2. Spark

Apache Spark is another popular framework written in Scala. It is very popular in the Big Data world and can be used to analyze a huge set of data in a quick time. Spark is an open-source cluster computing platform. It provides an interface for programming entire clusters with implicit data parallelism and fault tolerance.

If you are thinking to move on Big Data or taking some Big Data projects then learning Spark can be a good idea. If you want to learn Spark, I highly recommend you check out this Apache Spark with the Scala course by Frank Kane on Udemy. It's both a practical and hands-on course to learn Spark online by yourself.

3. Play Framework

Just like Akka makes writing concurrent applications in Java and Scala easy, Play Framework makes it easy to build web applications with Java and Scala. Play is based on a lightweight, stateless, web-friendly architecture that takes advantage of highly concurrent and scalable Akka framework for writing a highly scalable web application.

Play provides predictable and minimal resource consumption (CPU, memory, threads) for highly-scalable applications. Along with Akka, Play is two of the most popular Scala framework and if you want to learn Play, you can use this Play Masterclass course on Udemy to start with.

4. Slick

Slick is a modern database query and access library for Scala. It allows you to work with stored data almost as if you were using Scala collections while at the same time giving you full control over when a database access happens and which data is transferred.

You can write your database queries in Scala instead of SQL, thus profiting from the static checking, compile-time safety, and compositionality of Scala. Slick features an extensible query compiler that can generate code for different backends.

If you want to learn Slick in 2020 and looking for good resources then you can also check out this Kickstart SCALA - The UItimate Scala Beginner Bootcamp course on Udemy. It touches base on all important Scala frameworks including Slick for the database.

5. Grails

Grails is a powerful Groovy-based web application framework for the JVM which is built on top of the Spring Boot, another popular framework for Java development. Grails, like Ruby on Rails, aims to simplify Java development by leveraging Groovy's simplicity and expressiveness.

Grails adopts best practices from popular Java framework like its use of convention-over-configuration, sensible defaults, opinionated APIs, and the Groovy language combine to make Grails easy to learn for Java developers.

Another good thing about Grails is that it seamlessly and transparently integrates and interoperates with Java, the JVM, and existing Java EE containers.

If you are into Java web development then learning Grails can be a good addition to your skill. If you want to learn Grails and need a resource then I suggest you check out this Grails MasterClass on Udemy.

6. Gradle

Gradle is probably the most popular tool written in Groovy. It was initially touted as a replacement of Maven becuase of crisp and concise build files which removed the boilerplate of XML from the pom.xml file but now it co-exists with Maven.

Though more and more developers are moving to Gradle for simpler and easy to read build files and in the future it may really become the go-to build tool for Java developers and Java applications.

It's a good tool to learn especially if you are a hands-on Java developer and if you want to learn Gradle then you can check out this Gradle MasterClass course on Udemy.

7. Spock Testing Framework

If you are passionate about testing in Java then you might have heard about Spock, one of the best Groovy frameworks for unit testing and specification. You can use Spock to write a unit test for not just Groovy apps but also Java applications.

What makes it stand out from the crowd is its beautiful and highly expressive specification language. Thanks to its JUnit runner, Spock is compatible with most IDEs, build tools, and continuous integration servers. Spock is inspired by JUnit, RSpec, jMock, Mockito, Groovy, Scala, Vulcans, and other popular Java tools.

There are not many resources to learn Spock online but Learn Automation with Geb and Spock on Udemy is the best course to start with

And, if you love books then this Java Testing with Spock book on Manning is probably all you need to get started with Spock.


8. Monix

Monix is another high-performance Scala / Scala.js library for composing asynchronous, event-based applications.
It started as a proper implementation of ReactiveX, with stronger functional programming influences and designed from the ground up for back-pressure and made to cleanly interact with Scala’s standard library, compatible out-of-the-box with the Reactive Streams protocol.

There is not much resource to learn Monix online like I didn't find any book or course but their Documentation is good and you can use them to learn Monix by yourself.

9. Lift

Lift is one of the most powerful and secure web framework available today. It is a free and open-source web framework that is designed for the Scala programming language. It was originally created by David Pollak who was dissatisfied with certain aspects of the Ruby on Rails framework.

Since Lift applications are written in Scala which is compatible with Java, you can still use your favorite Java libraries and deploy to your favorite Servlet Container and app server.

Scala allows you to use the code you've already written and deployed to the container you've already configured! If you want to learn Lift in 2020 and looking for a great resource then you can also check out this Lift MasterClass in Udemy.

10. Lagom

This is another Scala framework for building microservices using Scala tools and frameworks. It's actually a platform that provides you complete toolset for building, managing, and monitoring high-performance and non-blocking microservices.

This frameworks targets Java developers but uses Scala's powerful tools and technologies like:
  •     SBT (Scala’s build system, project definitions),
  •     Play (REST endpoints, Guice dependency injections)
  •     Akka (processing)
  •     Cassandra (default data storage)

Most of the technologies are hidden behind the interface so you don't need to worry. It's still fairly new but also offers an alternative of Spring Boot, Micronaut, and Quarkus for building Microservices in the Java world.

That's all about some of the best Scala and Groovy frameworks that Java developers can learn and use in their projects. It's worth remembering that Grails and Play can be used to develop web applications, while Gradle can help you build your application like Maven. Akka is a concurrency framework, while Spark is a Big data framework, and Spock is used for data-driven unit testing.
