There are very few things in Grain framework that need a detailed explanation except being described in the docs. However, there's one thing, which I really want to clarify in details for Grain users. I wanted to write an article for the people who seek for simple instructions for implementing tasks that require complex manipulation to site pages, like including information from one page to another, creating or replacing pages, etc. As an example, in this guide I will tell you how to create paginated blog archive for your site.
Grain theme is a project that provides a layout-based skeleton for creating static websites by only adjusting the configuration and adding a content. This post shows how to use the theme template in order to create a custom Grain theme — starting from defining content files and page layouts, and up to building user-friendly, page-formatting tools.

With the latest performance enhancements and great dynamic, functional and meta-programming features Groovy becomes a very good choice not only for scripting, but also for big and complex application building. Long term complex application development requires extensive unit testing utilization to allow moving forward without breaking existing features. Groovy plays nicely with powerful Spring framework, which can be used to make application easily extensible and unit testing friendly.
Enterprise application might be developed using a variety of architectural styles. And REST is one of the most powerful of them. It allows us to build simple, scalable, highly productive APIs with independent components on the basis of widespread standards like HTTP, MIME etc, engaging their true potential.
Let's discuss how to create a lightweight, but full-featured RESTful service from scratch.
I'm using Slick library in my project and need to ensure that all required MySQL tables are created on application start.

Below is tiny example of how to do that.
This example shows how to use pagination and sorting with many-to-many relationship in Grails.
When Groovy has grown up to version 2, it has gained a lot of brand new features and improvements in areas of productivity and security. Groovy now provides the ability to statically type check and statically compile your Groovy code for robustness and performance. This is very useful when you don't need Groovy's dynamic features, or simply want to speed up performance of your scripts.
