Umbraco Icons

This handles custom icon registration in Umbraco's backoffice using the official extension system. You'd use it when building Umbraco packages that need branded or custom SVG icons beyond the default set. It pulls fresh documentation before generating code, which matters since Umbraco's extension API changes between versions. The workflow is straightforward: it fetches the latest docs, asks what icons you need, then generates the manifest and TypeScript files with proper lazy loading. The source includes references to working examples in the Umbraco CMS repo, so you're not guessing at patterns. Good for package authors who want icons that match their brand without digging through backoffice documentation.

Umbraco Icons

What is it?

Icons are custom visual elements that extension authors can register for use throughout the Umbraco backoffice. Custom icons are registered through the manifest and can then be used in any extension that accepts an icon property. Icons are defined as SVG content exported from JavaScript modules.
