Grails and AngularJs are two incredible frameworks and with the newer REST features of Grails they can be a pretty nice pairing. That isn't to say that there isn't some work involved in getting them to play well together though.
I've also created an example app that makes use of these two plugins and includes some directives and services to make development a bit easier (similar to Rob Fletcher's Grails Angular Scaffolding project).
You can see a demo of the app here: Grails Angular App Demo
Here's an overview of my Angular related projects:
This is a lazybones template that hopefully provides a good jumping off point for anyone looking to use Grails and AngularJS together. I'm still actively tweaking and improving upon this project. Any feedback or suggestions are certainly welcome.
This allows you to create static templates from html or gsp files that get inserted into Angular's $templateCache.
As a side benefit it promotes a nice organization based on the module name. For example a template for the module myApp.directives.buttons would be placed in /assets/templates/my-app/directives/buttons.
This plugin also allows you to define your static Angular templates using the fields plugin or other Groovy expressions. This lets you use Angular without having to lose all the niceties you get with GSPs.
If you decide to use any of these projects or have any feedback please let me know. I'd love to hear how other people are using Grails and AngularJS together
