+# [%title]
+
+You can render a model into JSON with a [JSON View](http://views.grails.org/latest/#_json_views) within a [Grails](https://grails.org) service: 
+
+Given the following view:
+
+`grails-app/views/apiContact/_contact.gson`
+
+```groovy
+import example.Contact
+
+model {
+    Contact contact
+}
+json {
+    fullname contact.name
+}
+```
+
+You can create a service such as: 
+
+```groovy
+package example
+
+import grails.plugin.json.view.JsonViewTemplateEngine
+import groovy.text.Template
+import org.springframework.beans.factory.annotation.Autowired
+
+class JsonViewRenderingService {
+    @Autowired
+    JsonViewTemplateEngine jsonViewTemplateEngine
+
+    Writable renderWritable(String templatePath, Map<String, Object> model) {
+        jsonViewTemplateEngine.resolveTemplate(templatePath)
+            .make(model)
+    }
+
+    String render(String templatePath, Map<String, Object> model) {
+        renderWritable(templatePath, model)
+            .writeTo(new StringWriter())
+            .toString()
+    }
+}
+```
+
+Which you can call from other Grails Artifacts: 
+
+```groovy
+jsonViewRenderingService.render('/apiContact/_contact',
+[contact: new Contact(name: 'Sergio')])
+```
+
