jahia-dev-ui-extension

To create a Jahia UI extension, you scaffold an OSGi module using the Jahia archetype and build it with Webpack and Module Federation to register custom actions, panels, and dialogs in jcontent.

Module Federation enables Jahia ui-extender modules to load remote React 18 components at runtime, allowing the jcontent back-office to dynamically integrate your custom UI extension without requiring a full application rebuild.

Yes, you can add a custom toolbar button and settings panel to jcontent by developing a UI extension module with React 18 and registering it via the @jahia/ui-extender registry to hook into the back-office interface.

You need to follow specific Jahia archetype scaffolding patterns to ensure proper module structure and runtime registration, which guarantees your OSGi UI extension integrates safely and consistently with jcontent APIs.

The best way to register actions and dialogs in Jahia jcontent is through the @jahia/ui-extender registry, which handles the runtime integration of your Webpack-built React 18 components into the back-office.

Limitations when extending Jahia jcontent include strict dependencies on React 18, Webpack, and Module Federation, meaning your custom UI modules must align with these specific framework versions and the OSGi architecture to function correctly.
