Clément Aubin developed a live data feed feature for extension compatibility on plan documents within the xwiki/xwiki-platform repository. Leveraging both back-end and front-end development skills, Clément used Java and JavaScript to enable real-time visibility of all extensions supporting a given ExtensionSupportPlanSheet. The implementation included dynamic synchronization of translations, ensuring that updates to extension compatibility were immediately reflected for users. This work improved the accuracy and efficiency of plan documentation by reducing the need for manual checks. Delivered as a complete end-to-end feature, the solution enhanced the user experience for evaluating extension compatibility on plan documents in XWiki.
