🚀 Getting Started

Prerequisites

Node.js 16+ and npm/yarn
Firebase account (free tier available)
Google Cloud Project with OAuth 2.0 credentials
Git

Quick Setup (Frontend Only - Demo Mode)

If you just want to see the UI without the backend, you can run the frontend:

cd frontend
npm install
npm run dev

Then open http://localhost:5173 in your browser.

Complete Setup (Frontend + Backend + Firebase)

Step 1: Clone Repository

git clone https://github.com/yourusername/CampusStack.git
cd CampusStack

Step 2: Firebase Setup

Go to Firebase Console
Create a new project named "CampusStack"
Enable Realtime Database (choose "Start in test mode")
Enable Google OAuth:
- Go to Authentication → Sign-in method
- Enable Google provider
Get your Firebase config from Project Settings → Your apps → Web app

Step 3: Google Cloud Setup

Go to Google Cloud Console
Create a new project
Enable APIs:
- Google Calendar API
- Google Drive API
Create OAuth 2.0 credentials (Web application)
- Add http://localhost:3000 and http://localhost:5173 to authorized origins
- Add http://localhost:3000/callback and http://localhost:5173/callback to authorized redirect URIs
Save your Client ID and Client Secret

Step 4: Environment Variables

Create .env file in project root:

# Firebase Config
VITE_FIREBASE_API_KEY=your_firebase_api_key
VITE_FIREBASE_AUTH_DOMAIN=your_project.firebaseapp.com
VITE_FIREBASE_PROJECT_ID=your_project_id
VITE_FIREBASE_STORAGE_BUCKET=your_project.appspot.com
VITE_FIREBASE_MESSAGING_SENDER_ID=your_sender_id
VITE_FIREBASE_APP_ID=your_app_id

# Google OAuth
VITE_GOOGLE_CLIENT_ID=your_google_client_id
VITE_GOOGLE_CLIENT_SECRET=your_google_client_secret

# Backend
VITE_API_URL=http://localhost:3001
NODE_ENV=development

Step 5: Backend Setup

cd backend
npm install

# Create .env file
cp .env.example .env
# Edit .env with your credentials

npm run dev

Backend runs on http://localhost:3001

Step 6: Frontend Setup

cd frontend
npm install
npm run dev

Frontend runs on http://localhost:5173

Default Test Accounts

Once the app is running, you can create accounts:

Admin Account (for CRUD operations):

Email: admin@campus.edu
Password: Admin@123

Student Account (for viewing):

Email: student@campus.edu
Password: Student@123

Login via Google OAuth or email/password authentication.

🔐 Authentication & Security

Authentication Flow

User clicks "Sign in with Google" or enters email/password
Firebase handles authentication (OAuth 2.0 or email/password)
Firebase returns auth token
Token stored in localStorage
All API requests include Authorization: Bearer <token> header
Backend validates token before processing requests

Role-Based Access Control

Student Role: Can only view data (read-only)
Admin Role: Can create, update, delete data
Middleware checks role on every protected endpoint
UI hides admin features from student accounts

Security Features

🔒 Google OAuth 2.0 (industry standard)
🔐 JWT tokens with expiration
🛡️ Role-based access control (RBAC)
🚫 CORS protection
📝 Environment variables for sensitive data
✅ Password hashing (bcryptjs)

� Troubleshooting

Frontend Won't Start

# Clear node_modules and cache
cd frontend
rm -r node_modules package-lock.json
npm install
npm run dev

Firebase Connection Error

Verify .env has correct Firebase credentials
Check Firebase project has Realtime Database enabled
Ensure authentication methods are configured
Check browser console for specific Firebase errors

Google OAuth Not Working

Verify Google OAuth credentials in .env
Ensure authorized redirect URIs include http://localhost:3000 and http://localhost:5173
Check browser cookies are enabled
Clear browser cache and localStorage

Real-Time Updates Not Working

Verify Firebase Realtime Database rules are set correctly
Check that users have proper authentication
Ensure rules allow read/write for authenticated users:

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

Port Already in Use

# Kill process using port (Windows)
netstat -ano | findstr :3001
taskkill /PID <PID> /F

# For Mac/Linux
lsof -ti :3001 | xargs kill -9

API Calls Return 401 Unauthorized

Token may have expired - user needs to re-login
Verify Authorization header is being sent
Check backend is validating tokens correctly
Ensure user has proper role for the endpoint
