May 2025 performance highlights for incubateur-ademe/territoires-en-transitions: Delivered a comprehensive overhaul of the indicators experience, including a new Indicators page with tabs, a dedicated Indicator List page added to the menu, and a route that returns the number of indicators the user pilots. Refactored the Indicator List UI/UX to DS standards, introducing a composite component that aggregates parameters, the list, and the filtering panel, along with improved tooltips, empty-state messaging, and a dedicated options/search bar. Implemented a new hooks-based data layer to manage list parameters and to read data for the current community, enabling personalized and accurate views. Aligned and integrated the indicator list usage with the tracking plan across the TDB module and the sub-indicators tab to improve analytics and governance. Enabled server-side default indicator list selection to simplify initial UX, and introduced a TRPC client usable in RSCs and server actions for safer, faster data access. Additional quality and reliability work included codebase cleanup (removing obsolete files and dependencies), lockfile repair, improved spreadsheet import handling, and UI markdown improvements, all contributing to better maintainability and developer velocity.
