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 best practices in ServiceNow. We looked at some of the best ways to use scripting in ServiceNow, and some bad practices to avoid. Our best practices included the areas of coding, business rules, and client scripts, as well as debugging, logs, queues, and system performance. We saw how these best practices work together to build a streamlined ServiceNow instance.

In the next chapter, we will look at using update sets. Update sets are a big part of moving functionality between instances of ServiceNow, and are widely used. We will look at when and how to use update sets and how they work in relation to scope. We discover how to move update sets between instances and the pitfalls to avoid when doing so. Finally, we take a look at best practices with update sets, so you can make the most of the ServiceNow application.
