The Scala Plugin is used to turn a normal IntelliJ IDEA into a convenient Scala development environment. In this article, we will discuss how to set up Scala Plugin for IntelliJ IDEA IDE.  If you do not have IntelliJ IDEA, you can download it from here.

By default, IntelliJ IDEA does not come with Scala features. Scala Plugin adds Scala features means that we can create Scala/Play Projects, we can create Scala Applications, Scala worksheets, and more.

Scala Plugin contains the following technologies:

  • Scala
  • Play Framework

  • Scala.js

It supports three popular OS Environments: Windows, Mac, and Linux.
