---

## 🚀 Next Steps (YOU NEED TO DO THESE)

### Step 1: Install Dependencies

**Backend:**
```bash

cd backend

pip install -r requirements.txt

```

**Frontend:**
```bash

cd frontend

npm install

```

---

### Step 2: Set Up Firebase

1. **Create Firebase Project:**
   - Go to https://console.firebase.google.com/
   - Create a new project or use existing one

2. **Enable Google Authentication:**
   - In Firebase Console → Authentication → Sign-in method
   - Enable "Google" provider
   - Set project support email

3. **Get Web App Config:**
   - Project Settings → Your apps → Add Web app
   - Copy the config values

4. **Get Service Account Key:**
   - Project Settings → Service accounts
   - Click "Generate new private key"
   - Download the JSON file

5. **Set Frontend Environment Variables:**
   Create `frontend/.env`:
   ```bash

   VITE_FIREBASE_API_KEY=your-api-key-here

   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

   VITE_API_BASE_URL=http://localhost:7860

   ```

6. **Set Backend Environment Variables:**
   Option A (JSON file path):
   ```bash

   FIREBASE_SERVICE_ACCOUNT_KEY=/path/to/service-account-key.json

   ```
   
   Option B (JSON string - recommended for Docker):
   ```bash

   FIREBASE_SERVICE_ACCOUNT_JSON='{"type":"service_account","project_id":"...","private_key":"...","client_email":"..."}'

   ```
   (Copy the entire JSON content from the downloaded file)

---

### Step 3: Set Up Brevo

1. **Create Brevo Account:**
   - Go to https://www.brevo.com/
   - Sign up (free tier: 300 emails/day)

2. **Get API Key:**
   - Settings → API Keys
   - Generate new API key
   - Copy the key (starts with `xkeysib-`)

3. **Verify Sender Email:**
   - Senders & IP → Senders
   - Add sender email (e.g., `noreply@yourdomain.com`)
   - Verify via email

4. **Set Backend Environment Variables:**
   ```bash

   BREVO_API_KEY=xkeysib-your-api-key-here

   BREVO_SENDER_EMAIL=noreply@yourdomain.com

   BREVO_SENDER_NAME=EZOFIS AI

   ```

---

### Step 4: Set JWT Secret

Generate a secure random key:
```bash

# Linux/Mac

openssl rand -hex 32



# Or Python

python -c "import secrets; print(secrets.token_hex(32))"

```

Set environment variable:
```bash

JWT_SECRET_KEY=your-generated-secret-key-here

```

---

### Step 5: Set Frontend URL

```bash

FRONTEND_URL=http://localhost:5173  # Development

# OR

FRONTEND_URL=https://your-domain.com  # Production

```

---

### Step 6: Database Migration

**If you have existing data:**
- The new schema will be created automatically
- Existing `extractions` table needs `user_id` column
- You may need to assign existing records to a default user

**For fresh start (recommended for development):**
- Delete `data/app.db` (if exists)
- Restart application - tables will be recreated

---

### Step 7: Test the Implementation

1. **Start Backend:**
   ```bash

   cd backend

   uvicorn app.main:app --reload --port 7860

   ```

2. **Start Frontend:**
   ```bash

   cd frontend

   npm run dev

   ```

3. **Test Firebase Login:**
   - Navigate to http://localhost:5173
   - Click "Google Sign In" tab
   - Sign in with business Google account
   - Should redirect to dashboard

4. **Test OTP Login:**
   - Click "Email / OTP" tab
   - Enter business email
   - Click "Send OTP"
   - Check email for OTP code
   - Enter OTP and verify
   - Should redirect to dashboard

5. **Test Business Email Validation:**
   - Try personal Gmail account → Should be blocked
   - Try OTP with personal email → Should be blocked

## 📝 Environment Variables Checklist

### Backend (.env or system environment)
- [ ] `FIREBASE_SERVICE_ACCOUNT_JSON` or `FIREBASE_SERVICE_ACCOUNT_KEY`
- [ ] `BREVO_API_KEY`
- [ ] `BREVO_SENDER_EMAIL`
- [ ] `BREVO_SENDER_NAME`
- [ ] `JWT_SECRET_KEY`
- [ ] `FRONTEND_URL`

### Frontend (.env)
- [ ] `VITE_FIREBASE_API_KEY`

- [ ] `VITE_FIREBASE_MESSAGING_SENDER_ID`
- [ ] `VITE_FIREBASE_APP_ID`
- [ ] `VITE_API_BASE_URL`

---

## 🔒 Security Reminders

1. ✅ Never commit API keys or secrets to git
2. ✅ Use `.env` files (add to `.gitignore`)
3. ✅ Business email validation is enforced on both frontend and backend
4. ✅ JWT tokens expire after 7 days
5. ✅ OTP codes expire after 10 minutes
6. ✅ Maximum 5 OTP verification attempts

## ⚠️ Important Notes

1. **Database Schema Change:**
   - User model changed from `google_id` (required) to `firebase_uid` (optional)
   - If you have existing users, you'll need to migrate the data
   - For development, deleting `data/app.db` is the easiest option

2. **Business Email Validation:**
   - Personal email domains are blocked (Gmail, Yahoo, Outlook, etc.)
   - Validation happens on both frontend and backend
   - Users must use their work/corporate email addresses

3. **OTP Storage:**
   - Currently stored in memory (works for single server)
   - For production with multiple servers, consider using Redis

---

## 🎉 You're All Set!

Once you complete the setup steps above, your application will have:
- ✅ Firebase Google Sign-in (no OAuth credentials needed!)
- ✅ Email/OTP authentication via Brevo
- ✅ Business email validation
- ✅ User-specific data isolation
- ✅ Secure JWT token authentication

Good luck! 🚀
