What are scoped apps?

Scoped applications are a way to organize and isolate application code within the ServiceNow platform. They create a separate namespace for tables, scripts, and other application components, preventing conflicts with other applications.

Why are scoped apps important?

Scoped applications allow you to create and manage applications without affecting other applications on the platform. This helps maintain code organization, improve security, and reduce the risk of conflicts.

What is the benefit of using a scoped app?

Scoped app development uses a specific namespace for all its components, preventing conflicts between different apps. It helps maintain the integrity and stability of the platform.

What is application development on the Now Platform?

Building applications on the Now Platform involves creating solutions to automate tasks and processes that are traditionally handled manually.

What is the difference between global scope and scoped app?

Global scope is a shared namespace for all applications, allowing for greater accessibility and data sharing but potentially leading to conflicts. Scoped apps provide a more secure and organized approach.

Scoped App

A feature in ServiceNow that isolates application data and code, preventing unintended modifications by other applications. Each scoped app has its own namespace, making its resources unique and protected.

Global Scope

The default application scope in ServiceNow where all applications share the same namespace. It's like a common ground where everyone can access and modify resources.

Uninstall

It's a simple and efficient method for backing out changes made to a scoped app. Unlike update sets, where you need to revert each change individually, you can revert all changes with a single action.

Study Notes

Scoped Apps in ServiceNow

  • Scoped apps (private application scope) are used to isolate application resources, preventing unintended modifications or conflicts between applications.
  • Scoped apps are created for extending or modifying existing applications or creating entirely new ones.
  • They are designed for easier management and change control during application development, deployment, and upgrade.
  • Developers should use scoped apps to create new applications and extend existing applications.
  • Existing applications can be modified, preventing unwanted impacts on other applications.

Application Scoping

  • Scoped apps have a unique namespace, preventing access to artifacts from other apps unless explicit permission is given.
  • This enforces isolation between different applications, ensuring development changes don't interfere with other applications.
  • Global scope applications are shared resources, accessible to all application developers.

Scoped App Creation and Use

  • Scoped apps are created using the Studio IDE.

  • Any user with system administrator privileges can develop within a scoped app container.

  • Any type of application can be scoped.

  • Application scopes were introduced in March 2015 (Fuji release).

  • Existing global applications can be made into scoped apps, but this is not a direct migration process.

Global Scope vs Scoped Apps

  • When extending an existing global scope application, scope the changes if they impact a limited number of applications.
  • New applications should be created as scoped apps for easier updates and easier upgrade processes.
  • Any application built in global scope, can be built as a scoped app.
  • Global artifacts need to be copied into the scoped app or marked as accessible.

Functionality and APIs

  • All core Now Platform services (workflow, business rules, UI policies) work in scoped apps.
  • Global artifacts (tables and scripts) marked accessible work with scoped apps.
  • Certain out-of-the-box APIs might not work in scoped apps; refer to the API documentation.
  • All custom apps built in global scope or before application scoping can still be utilized, but it may require rewriting of the application to make the application accessible under a scoped app.

Migration and Update Sets

  • Moving apps between global and scoped app is not recommended, and tools don't exist for automated migration.
  • Update sets work in scoped apps similar to global scope, but using the "publish" capability is recommended for moving scoped apps from one instance to another.
  • Publish ensures dependencies are checked and provides an easy rollback by uninstalling and re-installing the previous deployment.

Challenges and Best Practices

  • Global scope artifacts used in scoped apps need to be replicated or encapsulated (using script includes) for proper access.
  • Proper documentation of changes is essential for easier analysis and upgrade management.
  • Using publish, not update sets, is preferred for moving scoped apps.
  • Avoid attempting to migrate applications between global and scoped scopes.
  • Always check available APIs to ensure proper functionalities.
