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.

Summary


In this chapter, we looked at using exposed JavaScript APIs and the well-used GlideRecord class. We also looked at server-side and client-side Glide classes and the properties and methods of each that can be used to enhance your scripting. Finally, we looked at some more complex examples of scripting, combining these properties and methods to show what can be achieved and how the properties and methods can be used together.

In the next chapter, we will explore the basics of client-side scripting. We will look at client scripts, UI policies, when to use these scripts, and how to test them. Plus we'll add some helpful examples to show some great ways to get the most out of client-side scripting.
