What Type of Scripting Does ServiceNow Use?


Angela Bailey

When it comes to scripting in ServiceNow, there are primarily two types that are commonly used. These scripting languages are essential for customizing the platform and automating processes. In this article, we will explore both of these scripting options and understand their significance in the ServiceNow ecosystem.

The Glide System

The Glide System is a powerful and versatile scripting API provided by ServiceNow. It is built on top of JavaScript and offers a rich set of functions and methods that can be used to manipulate data, interact with the platform, and create custom business logic.

Using the Glide System, you can perform various tasks such as querying records, updating fields, creating new records, sending notifications, and much more. It provides a straightforward way to access and modify data within the platform.

Benefits of Using the Glide System

  • Simplicity: The Glide System is built on JavaScript, which makes it easy to learn and use for developers familiar with the language.
  • Flexibility: It offers a wide range of APIs that allow developers to customize workflows, business rules, UI actions, and other aspects of the platform.
  • Integration: The Glide System can seamlessly integrate with other scripting languages like Jelly or AngularJS to create powerful solutions.
  • Security: It provides built-in security mechanisms like access controls and data encryption to ensure data integrity within the platform.

Jelly Scripting

Jelly is another scripting language used in ServiceNow. It is an XML-based language specifically designed for creating dynamic content in ServiceNow’s user interface. Jelly scripts are primarily used for defining UI pages, UI macros, UI policies, and other UI-related components.

Jelly scripts allow you to define reusable components, control the visibility of UI elements, and dynamically render content based on data from the platform. It provides a declarative way to define UI logic without the need for complex JavaScript code.

Advantages of Jelly Scripting

  • Separation of Concerns: Jelly scripting allows developers to separate the presentation logic from the underlying business logic, improving code maintainability and reusability.
  • Customizability: It provides a high degree of customization for UI components, allowing developers to create tailored user experiences.
  • Integration: Jelly scripts can be easily integrated with other scripting languages like JavaScript or server-side scripting languages like Python or Ruby.
  • Extensibility: It allows you to extend ServiceNow’s functionality by creating custom UI components that meet specific business requirements.

In conclusion, ServiceNow makes use of two primary scripting languages – the Glide System and Jelly. While the Glide System is used for server-side scripting and manipulating data within the platform, Jelly is primarily used for defining dynamic user interfaces. Both scripting options offer unique advantages that enable developers to customize and extend ServiceNow’s capabilities.

So whether you are working on creating custom workflows, automating processes, or developing user-friendly interfaces in ServiceNow, understanding these scripting languages will be crucial for your success!
