Question

Besides the sample applications featured in the books Beginning Groovy and Grails and The Definitive Guide to Grails, are there any applications out there written in Grails that are good examples from which to learn best practices? Such as real applications that are open-source?

Answer 1

During my learning phase, I came across several good sample applications.

This sample web album app got me started on grails. It covers security, image upload / manipulation, basic crud etc.

Here’s another one by Glen, a blog engine written with grails:
