Mastering ServiceNow Scripting

By: Andrew Kindred

Overview of this book

Industry giants like RedHat and NetApp have adopted ServiceNow for their operational needs, and it is evolving as the number one platform choice for IT Service management. ServiceNow provides their clients with an add-on when it comes to baseline instances, where scripting can be used to customize and improve the performance of instances. It also provides inbuilt JavaScript API for scripting and improving your JavaScript instance. This book will initially cover the basics of ServiceNow scripting and the appropriate time to script in a ServiceNow environment. Then, we dig deeper into client-side and server-side scripting using JavaScipt API. We will also cover advance concepts like on-demand functions, script actions, and best practices. Mastering ServiceNow Scripting acts as an end-to-end guide for writing, testing, and debugging scripts of ServiceNow. We cover update sets for moving customizations between ServiceNow instances, jelly scripts for making custom pages, and best practices for all types of script in ServiceNow. By the end of this book, you will have hands-on experience in scripting ServiceNow using inbuilt JavaScript API.

Once all of the testing has been completed, we can then move on to deploying our custom application to other instances. We can deploy our custom application once we have completed it in the following three main ways:

  • Publish the application to an update set
  • Publish to the application repository
  • Publish to the ServiceNow store

Let's have a look at how to deploy using each method.

Publish to an update set

The first method we will look at is how to publish the custom application to an update set. This is a very helpful method as this allows the update set to be sent to other instances as a retrieved update set, or even exported and imported on any ServiceNow instance. This makes this method of deployment arguably the most versatile.

To publish a custom application to an update set, we first need to navigate to the application record. To do this, we can navigate to System Applications | Applications and then click on the name of the application. Make sure not to click on edit as this will...
