HappyPlants is a mobile-first progressive web application (PWA) for managing houseplant care. The core functionality allows users to create and organize plant entries, tracking details like watering schedules, sunlight requirements, growth cycles, notes, and photos. It is implemented as a Vue.js 2 SPA with Vuex state management and vue-router, using Firebase (Authentication, Firestore, Storage) for cloud sync with an offline-first fallback via localforage (IndexedDB). The repository is a monorepo managed by Lerna, containing two parallel application versions: an archived v1 (JavaScript) and an evolving v2 alpha (TypeScript with @vue/composition-api), plus a landing page (Nuxt.js), an unused Express server, Firebase Cloud Functions, and shared packages for components and styles. Key entry points include main.js/main.ts bootstrapping, router definitions, and a Vuex store organized by domain modules. The app relies heavily on the Vue ecosystem, Firebase, and utility libraries like anime.js for animations and localforage for local storage. While the core concept is well-executed with tests and responsive design, the codebase exhibits duplication between v1 and v2, some deprecated dependencies, and an incomplete v2 rewrite, limiting overall craftsmanship.
