October 2025 performance summary for Inist-CNRS/lodex: Delivered core features to strengthen internationalization, form handling, and data enrichment, while stabilizing the UI/tests and modernizing the tech stack. Implemented useTranslate hook to standardize i18n across components; migrated Field Forms to react-hook-form to simplify form management; removed Redux usage around field preview and save actions to reduce complexity; updated the enrichment API controller to support newer data handling; consolidated UI components for Switch and AutoComplete to improve consistency and reuse. Also advanced the TypeScript migration across workers/ezsLodex and enabled tsx-based runtime for worker processes, restructured packaging for modularity, and completed CI/build improvements for multiple dev servers. Major improvements to testing reliability (Cypress/Jest), and release readiness with version bumps to 16.0.5.
