Tech Stack

Frontend

• Framework: React 19.2.0 with React Router 7.13.1
• Build Tool: Vite with rolldown-vite 7.2.5
• Styling: MUI 7.3.8, Emotion CSS-in-JS
• UI Components: FontAwesome icons, Lucide React icons
• Data Visualization: Recharts 3.8.1
• Linting: ESLint 9.39.1

Backend

• Database: Supabase (PostgreSQL)
• Authentication: Supabase Auth
• Real-time: Supabase Realtime subscriptions

Performance

• Bundle Optimization: Manual Vite chunk splitting (react-vendor, charts-vendor, supabase-vendor, ui-vendor)
• Code Splitting: Lazy-loaded Dashboard component
• Caching: Optimized vendor chunks for browser cache reuse

Installation

Prerequisites

• Node.js 18+ and npm 9+
• Supabase account with configured PostgreSQL database

Setup

1. Clone the repository:

git clone <repository-url>
cd react-appp

2. Install dependencies:

npm install

3. Configure environment variables: Create a .env.local file with:

VITE_SUPABASE_URL=<your-supabase-url>
VITE_SUPABASE_ANON_KEY=<your-supabase-anon-key>

4. Start development server:

npm run dev

The app will be available at http://localhost:5173

🚀 Development

Available Commands

Command	Description
npm run dev	Start development server with HMR
npm run build	Build optimized production bundle
npm run lint	Run ESLint to check code quality (0 errors/warnings)
npm run test	Run lint as deployment gate
npm run preview	Preview production build locally

Development Notes

• HMR (Hot Module Replacement) enabled for instant feedback
• Strict ESLint rules configured for code quality
• All linting checks pass with zero errors/warnings
• Async-wrapped effect calls to prevent setState-in-effect issues

🔑 Key Architecture Decisions

State Management

• localStorage + Supabase: Notification preferences persist locally for instant feedback, synced to Supabase
• React Context + Props: Simple, predictable state flow through component hierarchy
• useAppData Hook: Centralized async data fetching with schema-safe fallbacks

Database Resilience

• Query Fallbacks: Graceful degradation when schema columns missing (e.g., due_time field)
• Periodic Polling: 60-second refresh intervals for inbox notifications
• Dual-layer Persistence: localStorage immediate sync + Supabase best-effort background sync

UI/UX

• CSS Pseudo-elements: Unread notification indicators using ::before accent stripes
• Modal Dialogs: Deadline reminders as non-blocking popups with "Mark as Read" and "Open Inbox" actions
• Friend Toggle: Same button for request/unrequest with intelligent state detection

Performance

• Vendor Chunk Splitting: 5 isolated vendor chunks reduce entry bundle to ~24 kB, dashboard to ~112 kB
• Lazy Loading: Dashboard component loaded on demand
• Route-based Code Splitting: Separate bundles for auth pages vs. app pages

✅ Deployment Readiness

This application has been thoroughly audited and optimized for production:

• ✅ All ESLint checks pass (0 errors, 0 warnings)
• ✅ Production build validated and optimized
• ✅ Notification system fully functional (persistent, scheduled, modal alerts)
• ✅ Friend system toggleable and reliable
• ✅ Bundle performance optimized with vendor chunk splitting
• ✅ Database queries include schema-safe fallbacks
• ✅ All runtime functions defined and tested
• ✅ localStorage + Supabase persistence working

Deployment Checklist

• Configure production Supabase environment variables
• Run npm run test to verify lint gate passes
• Run npm run build to generate optimized bundle
• Deploy build output to hosting platform (Vercel, Netlify, etc.)
• Verify deadline reminders pop up within 24 hours of task due date
• Test friend request toggle functionality
• Confirm notification preference persistence across page reloads

🐛 Known Patterns & Troubleshooting

Deadline Reminders Not Displaying

• Check that task due_time is set and within 24 hours
• Verify localStorage key: ${username}_taskReminderRead
• Confirm inbox refresh is running (60-second intervals)

Notification Settings Not Persisting

• Ensure localStorage is enabled in browser
• Verify Supabase notification_settings table exists
• Check username-prefixed localStorage keys are readable

Friend Request Issues

• Confirm friendships table relationships (user_id → friend_id directionality)
• Friend unrequest uses same button as request (checks existing friendship status)
• Outgoing friend requests can be canceled by pressing request button again

📄 Database Schema Notes

Key tables referenced by this application:

• tasks: Task definitions with due dates
• sessions: Work session tracking
• friendships: User relationships (with status: pending, accepted)
• notification_settings: User notification preferences
• task_reminders: Deadline reminder tracking

🤝 Contributing

When making changes:

1. Run npm run lint before committing to ensure code quality
2. Test all notification features work as expected
3. Verify friend system toggles correctly
4. Check localStorage persistence for settings
