Umbraco Entry Point

This generates Umbraco backoffice entry points that run on startup after authentication. It fetches the latest official docs before writing code, which is smart since Umbraco's extension system can shift between versions. You'd reach for this when you need to initialize something globally, load external libraries, or register UI extensions dynamically at runtime instead of statically in manifests. The workflow is straightforward: it asks what you're trying to initialize, pulls fresh documentation, then generates both the manifest and TypeScript implementation with optional cleanup handlers. Saves you from digging through docs yourself and gets the boilerplate right.

Umbraco Entry Point

What is it?

Entry Points are extensions that execute JavaScript code when the Umbraco backoffice starts up. The Backoffice Entry Point runs after user authentication and is used for initialization logic, loading external libraries, registering UI extensions dynamically, or including global CSS. An optional onUnload function handles cleanup.

Documentation

Always fetch the latest docs before implementing:

Workflow

Fetch docs - Use WebFetch on the URLs above
Ask questions - What initialization is needed? Any external libraries? Cleanup required?
Generate files - Create manifest + entry point based on latest docs
Explain - Show what was created and how to test
