No direct support is provided for RSS or Atom within Grails. You could construct RSS or ATOM feeds with the render method's XML capability. There is however a Feeds plug-in available for Grails that provides a RSS and Atom builder using the popular ROME library. An example of its usage can be seen below:

def feed = {
    render(feedType:"rss", feedVersion:"2.0") {
        title = "My test feed"
        link = "http://your.test.server/yourController/feed"

Article.list().each() { entry(it.title) { link = "http://your.test.server/article/${it.id}" it.content // return the content } } } }
