March 2025 delivered a comprehensive codebase cleanup and tooling modernization, broad component refactors for consistency, and substantial UI/UX improvements across opencloud-eu/web. Key migrations moved core components to script setup (Files, Packages, Admin Settings, SpaceDetails, ResourceTiles, etc.) and refactored design-system utilities to improve maintainability and performance. The release also prioritized reliability with extensive testing enhancements (jsdom adoption, nextTicks helper, and updated snapshots) and UI fixes (tooltip redesign, loading indicators, right sidebar counts, and selection behavior). Security and configuration correctness were strengthened via explicit edition handling in opencloud-eu/reva, external app script setup improvements, and SpaceQuota script setup migrations. Additionally, logo upload was removed and documentation updated to reflect changes, reducing support overhead and aligning user expectations.

Feb 1, 2025

February 2025 (2025-02) monthly summary for opencloud-eu/web. Focused on extending platform extensibility, stabilizing the Design System, and tightening release readiness. Key features delivered include a Preferences panel extension system with bootstrap-registered extensions and an App Tokens panel, plus accompanying developer docs and UI border fixes. The Design System underwent a major refactor to script setup across components, added a parser for emits/props/slots, and consolidated prop/slot/emit APIs into a single API component; introduced VitePress-based docs and improved test alignment. Additional features include reworked runtime app tokens and Web package dependencies to avoid CDN loading. UX improvements such as mobile sidebars and removal of CollapsibleTable were implemented. Major bugs fixed cover UI and stability: hidden tooltips in collapsed sidebars, account page margins, OcSelect slot name validation, OcProgress and OcProgressPie color handling, ESLint config issues, and various type/inference/build/test fixes. These changes reduce runtime dependencies, stabilize the test suite, and prepare for release increments. Technologies and skills demonstrated include Vue 3 with script setup, Vite, Vitest, TypeScript, ESLint/Prettier, VitePress for docs, and comprehensive design-system tooling. Business value: faster feature delivery through extensible extension points, a more maintainable Design System, and a smoother, more reliable release process.
