The DataWeave Playground is an integrated development environment that enables you to experiment with complex Mappings and Transformations outside of AnypointStudio. When we first looked at the Playground, a creation of Mariano De Achaval and the Mulesoft Dataweave team, it was an experimental version running inside of a Docker container. While still a work in progress, through the magic of GraalVM, the Playground runs sans Docker, as a binary on Mac, Linux and Windows.

In my earlier article Transformative Moments we started in the middle of the story, showing you how to get immediate value from the DataWeave Command Line interface (DW CLI). We went on to learn how to create Command Line Services which created information pipelines from data source to sink. Now we’ll rewind to the beginning of the story to talk about the most important piece of all, the DataWeave Playground.

We’ll begin by creating the DW CLI folder and the environment settings which are needed. To make these changes permanent you can add them to your path in the Windows environment dialog settings or to the ._bashrc _file in your Linux HOME directory.
