10.10.2 Creating JSON Views

JSON views go into the grails-app/views directory and end with the .gson suffix. They are regular Groovy scripts and can be opened in any Groovy editor.

Example JSON view:

  1. json.person {
  2.     name "bob"
  3. }
To open them in the Groovy editor in Intellij IDEA, double click on the file and when asked which file to associate it with, choose "Groovy"

The above JSON view produces:

  1. {"person":{"name":"bob"}}

There is an implicit json variable which is an instance of StreamingJsonBuilder.

Example usages:

  1. json(1,2,3) == "[1,2,3]"
  2. json { name "Bob" } == '{"name":"Bob"}'
  3. json([1,2,3]) { n it } == '[{"n":1},{"n":2},{"n":3}]'

Refer to the API documentation on StreamingJsonBuilder for more information about what is possible.
