What happens when you create a new AppUI Oracle Application Extension in VB Studio?

When you create a new AppUI Oracle Application Extension in Visual Builder Studio (VB Studio), the action scaffolds a new set of source files (metadata, HTML, JavaScript, etc.) within your project's workspace. This workspace is backed by a Git repository. The extension exists purely in this design-time environment and is not deployed to any live instance. Deployment to the Oracle Fusion Cloud Applications instance is a separate, explicit action that you initiate through a build and deployment pipeline after you have developed and tested your extension. Therefore, none of the provided deployment or overwrite options (A, B, C, D) occur upon the initial creation of the extension.

A. The extension is deployed on the Fusion Application instance: Deployment is a distinct, subsequent step performed via a CI/CD pipeline after the extension is created and developed, not during creation.

B. The extension is deployed on a stand-alone Visual Builder instance: The extension is developed within the integrated VB Studio environment; it is not deployed to a separate, stand-alone instance upon creation.

C. The extension is deployed to the Fusion Apps database: The extension's source files are stored in the project's Git repository upon creation, not deployed to the Fusion Applications database.

D. The extension overwrites an existing page in Fusion Applications: Extensions are designed to be layered safely on top of existing pages. Overwriting does not occur, and any changes are only applied after a successful deployment.

1. Oracle Visual Builder Studio Documentation

"Create an Application Extension": "When you create an application extension

VB Studio creates a workspace for you with a Git repository that contains the source files for your extension. You can then use the tools in the workspace to modify the source files." This section describes the creation of a workspace and Git repository

with no mention of automatic deployment.

2. Oracle Visual Builder Studio Documentation

"Deploy an Application Extension": "After you've developed and tested your application extension

you'll want to deploy it to your Oracle Cloud Application instance. To deploy your extension

you'll use a pipeline that contains a build job that packages and deploys the extension." This explicitly defines deployment as a separate process from creation and development.
