DataWeave Delight Notebook

Experience the DataWeave programming language through code snippets

About the Book

In 2021 I started to write small blog posts about DataWeave at Messages from mrhaki. The posts contain code samples of cool DataWeave features I just didn't want to forget.

The DataWeave Delight Notebook contains the blog posts about DataWeave previously mentioned on my blog. The posts have been edited slightly so they can be used for the book. The book gives a broad overview of all the great features we can find in the DataWeave language.
