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.

In this chapter, we looked at the configuration and customization of a ServiceNow instance, and when it is appropriate to use both. We also introduced the two script types: client- and server-side scripts. This chapter also explained the running order of scripts in ServiceNow, the importance of order 1000, and how this can affect script outcomes. We introduced preparing to script, with some considerations before starting; finally, we looked at the script editor. 

In the next chapter, we will look at the ServiceNow glide class. This will show you the script ServiceNow provides you, which can be used to complement your JavaScript. The glide class is a frequently used aspect of ServiceNow scripting, and understanding its use will allow you to write helpful basic scripts and serve as a great first step into writing more advanced code.
