8.1.7 More on JSONBuilder

The previous section on XML and JSON responses covered simplistic examples of rendering XML and JSON responses. Whilst the XML builder used by Grails is the standard XmlSlurper found in Groovy.

For JSON, since Grails 3.1, Grails uses Groovy’s StreamingJsonBuilder by default and you can refer to the Groovy documentation and StreamingJsonBuilder API documentation on how to use it.
