What problem does it solve?
Duplicative server-side logic across multiple ServiceNow apps creates maintenance burdens and inconsistent behavior. This skill provides a structured approach to building Script Includes using class-based patterns, client-callable (GlideAjax) implementations, and inheritance to promote reuse, testability, and scalable utilities.
Core Features & Use Cases
- Class-based Script Includes: Encapsulate logic in well-defined, reusable classes with clear interfaces and lifecycle.
- Client-callable (GlideAjax): Expose server-side methods to client scripts safely, with proper security checks and parameter handling.
- Extending & Inheriting: Extend out-of-the-box Script Includes and platform classes to tailor behavior without duplicating code.
- Common Design Patterns: Singleton, Factory, and Strategy patterns to manage configuration, object creation, and task routing.
- Guidance & Best Practices: Prerequisites, naming conventions, and testing approaches to ensure maintainable code across apps.
Quick Start
Create a basic Script Include named IncidentUtils with a simple class and a few methods, then call it from a client script using GlideAjax to fetch data.
