End-to-end development

Once an application has been created on an instance, we can move on to developing the application. When we are in the application scope of our application, all customizations are added to the application. We can either make changes to the instance in the same way we usually would do development outside of an application, for example, creating and amending scripts, or we can use the studio ServiceNow provides for us.

Studio

The studio was created by ServiceNow for use when creating custom applications. Some developers prefer the studio, as it shows the application in one place, whereas others prefer to develop as they would in the global scope.

To access the studio, navigate to System Applications | Studio. This will open a new tab in your browser and give us the opportunity to load one of the applications that have been created on the current instance.
