-# Mobile App Sync Testing Guide
-
-## Overview
-This guide helps you test the bi-directional synchronization between the Trackeep mobile app and web dashboard.
-
-## Prerequisites
-
-1. **Backend Server**: Ensure your Trackeep backend is running
-2. **Web Dashboard**: Access the web dashboard at `http://localhost:3000` (or your configured URL)
-3. **Mobile App**: Run the React Native app using:
-   ```bash
-   npm start
-   npm run android  # or npm run ios
-   ```
-
-## First Launch Setup
-
-1. **Server Configuration**: On first launch, the mobile app will show the server setup screen:
-   - Enter your backend URL (e.g., `http://localhost:8080`)
-   - Enter your credentials
-   - Test connection before completing setup
-
-2. **Authentication**: After setup, you'll be redirected to login with your existing credentials
-
-## Testing Real-Time Sync
-
-### Test 1: Create Content on Mobile, Verify on Web
-
-1. **On Mobile App**:
-   - Open the Dashboard
-   - Tap the FAB (+) button
-   - Create a new task, bookmark, or note
-   - Verify it appears in the mobile dashboard
-
-2. **On Web Dashboard**:
-   - Navigate to the corresponding section (Tasks, Bookmarks, or Notes)
-   - The new item should appear within seconds (if WebSocket is connected)
-   - If not, refresh the page to see the synced item
-
-### Test 2: Create Content on Web, Verify on Mobile
-
-1. **On Web Dashboard**:
-   - Create a new task, bookmark, or note
-   - Save the item
-
-2. **On Mobile App**:
-   - The item should appear automatically if real-time sync is working
-   - Pull to refresh on the dashboard to force sync
-   - Check the specific section to verify the item appears
-
-### Test 3: Offline Mode Testing
-
-1. **Enable Offline Mode**:
-   - Turn off internet connection on your mobile device
-   - The app should show "🔴 Offline" status
-
-2. **Create Content Offline**:
-   - Create several tasks, bookmarks, or notes
-   - Notice the pending changes counter increases
-
-3. **Restore Connection**:
-   - Turn internet back on
-   - App should show "🟢 Connected" and auto-sync
-   - Verify items appear on web dashboard
-
-### Test 4: Conflict Resolution
-
-1. **Simulate Conflict**:
-   - Create the same item on both mobile and web while offline
-   - Bring both online simultaneously
-   - Verify how conflicts are resolved (last write wins or merge)
-
-## Key Features to Test
-
-### Real-Time Updates
-- ✅ WebSocket connection status
-- ✅ Instant updates across devices
-- ✅ Connection recovery after disconnection
-
-### Offline Support
-- ✅ Offline data persistence
-- ✅ Pending changes tracking
-- ✅ Automatic sync when online
-- ✅ Manual sync button
-
-### Data Integrity
-- ✅ All data types sync correctly (tasks, bookmarks, notes)
-- ✅ Timestamps preserved
-- ✅ User associations maintained
-- ✅ Tags and metadata sync
-
-## Troubleshooting
-
-### Common Issues
-
-1. **WebSocket Connection Failed**:
-   - Check if backend WebSocket endpoint is accessible
-   - Verify firewall settings
-   - Check browser console for WebSocket errors
-
-2. **Sync Not Working**:
-   - Verify server URL in mobile app settings
-   - Check authentication tokens
-   - Review backend logs for sync errors
-
-3. **Offline Mode Not Detected**:
-   - Check network permissions on mobile device
-   - Verify NetInfo plugin is working
-   - Test with airplane mode
-
-### Debug Tools
-
-1. **Mobile App Debugging**:
-   ```bash
-   # Enable debug mode
-   npx react-native log-android
-   npx react-native log-ios
-   ```
-
-2. **Backend Logs**:
-   - Monitor sync endpoint logs
-   - Check WebSocket connection logs
-   - Review database transaction logs
-
-3. **Browser Console**:
-   - Monitor WebSocket connections
-   - Check for real-time update events
-   - Verify API responses
-
-## Performance Testing
-
-### Test Scenarios
-
-1. **Large Dataset Sync**:
-   - Create 100+ items on one device
-   - Measure sync time to other device
-   - Verify no data loss
-
-2. **Concurrent Updates**:
-   - Multiple users updating same data
-   - Test conflict resolution
-   - Verify data consistency
-
-3. **Network Conditions**:
-   - Test on slow networks (2G/3G)
-   - Test with intermittent connectivity
-   - Verify sync resilience
-
-## Expected Results
-
-### Successful Sync Indicators
-
-1. **Mobile App**:
-   - Status shows "🟢 Connected"
-   - Last sync time updates
-   - No pending changes counter
-   - Real-time updates received
-
-2. **Web Dashboard**:
-   - New items appear without refresh
-   - WebSocket connection established
-   - No sync errors in console
-
-### Performance Benchmarks
-
-- **Small items** (< 1KB): Should sync within 1-2 seconds
-- **Large items** (> 100KB): Should sync within 5-10 seconds
-- **Batch sync** (50+ items): Should complete within 30 seconds
-
-## Automated Testing
-
-For comprehensive testing, consider implementing:
-
-1. **Unit Tests**:
-   - Sync logic validation
-   - Offline queue management
-   - Conflict resolution
-
-2. **Integration Tests**:
-   - End-to-end sync workflows
-   - WebSocket connection testing
-   - API integration validation
-
-3. **E2E Tests**:
-   - Multi-device sync scenarios
-   - Offline/online transitions
-   - User interaction flows
-
-## Reporting Issues

-
-1. Device information (OS, version)
-2. Network conditions
-3. Steps to reproduce
-4. Screenshots of error messages
-5. Backend logs (if available)
-6. Browser console errors
-
-## Success Criteria

-# OAuth Service Configuration Changes
-
-## Summary of Changes
-
-### 1. CORS Configuration Updated
-- **Before**: Restricted to specific origins (`http://localhost:5173,http://localhost:8080`)
-- **After**: Allows all origins (`*`) for maximum flexibility
-- **Implementation**: Updated CORS middleware to handle wildcard origins properly
-
-### 2. Dynamic Client URL Detection
-- **Before**: Hardcoded default client URL (`http://localhost:5173`)
-- **After**: Dynamically determines client URL from:
-  - Query parameter `redirect_uri` (highest priority)
-  - Request `Origin` header
-  - Request `Referer` header
-  - Fallback to `DEFAULT_CLIENT_URL` environment variable
-- **Implementation**: Enhanced `initiateGitHubOAuth` function with URL parsing logic
-
-### 3. Service Domain Configuration
-- **Added**: New `SERVICE_DOMAIN` environment variable
-- **Purpose**: Identifies the OAuth service domain in logs and webhook responses
-- **Current Value**: `https://oauth.tdvorak.dev`
-
-### 4. Enhanced Webhook Handling
-- **Before**: Basic webhook processing with minimal logging
-- **After**: 
-  - Proper webhook secret configuration check
-  - Enhanced logging with service domain identification
-  - Detailed event type handling with better payload logging
-  - Response includes service domain information
-
-### 5. Environment Files Updated
-- **`.env`**: Updated with new configuration values
-- **`.env.example`**: Updated to reflect the new structure for other deployments
-
-## Key Benefits
-
-1. **Multi-domain Support**: Service can now handle requests from any domain
-2. **Dynamic Client Detection**: Automatically redirects users back to their originating domain
-3. **Better Debugging**: Enhanced logging makes troubleshooting easier
-4. **Production Ready**: Configuration is more flexible for different deployment scenarios
-
-## Security Considerations
-
-- While CORS is set to allow all origins, the OAuth flow itself remains secure
-- State parameter validation prevents CSRF attacks
-- JWT tokens are still properly validated
-- Webhook signature validation is in place (though secret needs to be configured)
-
-## Usage
-
-The service will now:
-1. Accept OAuth requests from any domain
-2. Automatically detect the client's origin for proper redirects
-3. Handle webhooks with better logging and domain identification
-4. Work seamlessly with the user's domain (`tdvorak.dev`) and any other domains

-# Centralized OAuth Service
-
-This is a **standalone OAuth service** that handles GitHub authentication and email verification for all users. Users never need to set up their own OAuth applications - everything is centralized.
-
-## 🎯 **How It Works**
-
-### **For Users:**
-1. **GitHub OAuth**: Click "Connect GitHub" → GitHub authorization → Automatic login with GitHub profile
-2. **Email Verification**: Enter email → Receive verification code → Verify email for 2FA
-
-### **For Developers:**
-1. **Zero setup** - No OAuth app creation needed
-2. **Simple integration** - Just redirect to our service
-3. **Secure authentication** - We handle all the complexity
-4. **User management** - Centralized user database
-
-## 🚀 **Quick Start**
-
-### **1. Setup the OAuth Service**
-
-```bash
-# Navigate to the OAuth service
-cd oauth-service
-
-# Run the setup script
-./setup.sh
-
-# Edit the .env file with your GitHub OAuth credentials
-nano .env
-
-# Start the service
-go run main.go
-```
-
-### **2. GitHub OAuth App Setup (One Time)**
-
-1. Go to GitHub Settings → Developer settings → OAuth Apps
-2. Create a new OAuth app with:
-   - **Application name**: Trackeep OAuth Service
-   - **Homepage URL**: `http://localhost:9090`
-   - **Authorization callback URL**: `http://localhost:9090/auth/github/callback`
-3. Copy the Client ID and Client Secret to `.env`
-
-### **3. Email Verification Setup (One Time)**
-
-1. Configure smtp.purelymail.com for sending verification emails:
-   - **SMTP Host**: `smtp.purelymail.com`
-   - **SMTP Port**: `587`
-   - **Username**: Your purelymail SMTP username
-   - **Password**: Your purelymail SMTP password
-2. Add SMTP credentials to `.env` file
-3. The service will send 6-digit verification codes for 2FA
-
-### **4. Integration in Your App**
-
-```javascript
-// Redirect to GitHub OAuth
-const connectGitHub = () => {
-  window.location.href = 'http://localhost:9090/auth/github?redirect_uri=' + 
-    encodeURIComponent(window.location.origin);
-};
-
-// Send email verification code
-const sendEmailVerification = (email) => {
-  fetch('http://localhost:9090/api/v1/email/send', {
-    method: 'POST',
-    headers: { 'Content-Type': 'application/json' },
-    body: JSON.stringify({ email })
-  }).then(response => response.json())
-    .then(data => {
-      if (data.demo_code) {
-        console.log('Demo verification code:', data.demo_code);
-      }
-    });
-};
-
-// Verify email code
-const verifyEmailCode = (email, code) => {
-  fetch('http://localhost:9090/api/v1/email/verify', {
-    method: 'POST',
-    headers: { 'Content-Type': 'application/json' },
-    body: JSON.stringify({ email, code })
-  }).then(response => response.json())
-    .then(data => {
-      if (data.verified) {
-        console.log('Email verified successfully!');
-      }
-    });
-};
-
-// Handle callback (works for both GitHub and Email)
-const handleCallback = () => {
-  const urlParams = new URLSearchParams(window.location.search);
-  const token = urlParams.get('token');
-  const username = urlParams.get('user');
-  
-  if (token) {
-    localStorage.setItem('token', token);
-    localStorage.setItem('username', username);
-    // Redirect to dashboard
-    window.location.href = '/app';
-  }
-};
-```

-# Trackeep Integration Guide
-
-## Architecture Overview
-
-This OAuth service is designed **only for authentication**. Trackeep instances (user-hosted) handle all GitHub data tracking directly.
-
-## How It Works
-
-### 1. User Authentication Flow
-1. User clicks "Login with GitHub" in Trackeep
-2. Trackeep redirects to: `https://oauth.tdvorak.dev/auth/github?redirect_uri=https://user-trackeep-instance.com`
-3. OAuth service handles GitHub authentication
-4. OAuth service redirects back: `https://user-trackeep-instance.com/auth/callback?token=JWT&user=username`
-
-### 2. What Trackeep Receives
-The JWT token contains:
-```json
-{
-  "user_id": 123,
-  "github_id": 456789,
-  "username": "johndoe",
-  "email": "john@example.com",
-  "access_token": "gho_16C7e42F292c6912E7710c838347Ae178B4a",
-  "token_type": "bearer",
-  "expires_at": 1738123456,
-  "exp": 1738123456,
-  "iat": 1737518656
-}
-```
-
-### 3. Trackeep GitHub API Access
-Trackeep instances can now make GitHub API calls using the user's `access_token`:
-
-```javascript
-// Example: Get user repositories
-const response = await fetch('https://api.github.com/user/repos', {
-  headers: {
-    'Authorization': `Bearer ${accessToken}`,
-    'Accept': 'application/vnd.github.v3+json'
-  }
-});
-
-// Example: Get commits for a repo
-const commits = await fetch(`https://api.github.com/repos/${owner}/${repo}/commits`, {
-  headers: {
-    'Authorization': `Bearer ${accessToken}`,
-    'Accept': 'application/vnd.github.v3+json'
-  }
-});
-```
-
-## Trackeep Implementation Guide
-
-### 1. OAuth Login Button
-```html
-<a href="https://oauth.tdvorak.dev/auth/github?redirect_uri=https://your-trackeep-instance.com">
-  Login with GitHub
-</a>
-```
-
-### 2. Handle OAuth Callback
-```javascript
-// In your /auth/callback route
-async function handleOAuthCallback(req, res) {
-  const { token, user: username } = req.query;
-  
-  // Decode and verify JWT
-  const jwtPayload = decodeJWT(token);
-  
-  // Store user session
-  req.session.user = {
-    id: jwtPayload.user_id,
-    username: jwtPayload.username,
-    email: jwtPayload.email,
-    githubAccessToken: jwtPayload.access_token,
-    tokenType: jwtPayload.token_type,
-    expiresAt: jwtPayload.expires_at
-  };
-  
-  // Redirect to dashboard
-  res.redirect('/dashboard');
-}
-```
-
-### 3. GitHub API Helper
-```javascript
-class GitHubAPI {
-  constructor(accessToken) {
-    this.accessToken = accessToken;
-  }
-  
-  async makeRequest(url) {
-    const response = await fetch(url, {
-      headers: {
-        'Authorization': `Bearer ${this.accessToken}`,
-        'Accept': 'application/vnd.github.v3+json'
-      }
-    });
-    return response.json();
-  }
-  
-  async getUserRepos() {
-    return this.makeRequest('https://api.github.com/user/repos');
-  }
-  
-  async getRepoCommits(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/commits`);
-  }
-  
-  async getRepoPulls(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/pulls`);
-  }
-  
-  async getBranches(owner, repo) {
-    return this.makeRequest(`https://api.github.com/repos/${owner}/${repo}/branches`);
-  }
-}
-```
-
-### 4. Track Data Collection
-```javascript
-// Example: Track repository activity
-async function trackRepositoryActivity(user, repoFullName) {
-  const [owner, repo] = repoFullName.split('/');
-  const github = new GitHubAPI(user.githubAccessToken);
-  
-  // Get commits
-  const commits = await github.getRepoCommits(owner, repo);
-  
-  // Get pull requests
-  const pulls = await github.getRepoPulls(owner, repo);
-  
-  // Store in your local database
-  await storeActivityData({
-    userId: user.id,
-    repo: repoFullName,
-    commits: commits.length,
-    pullRequests: pulls.length,
-    lastActivity: new Date()
-  });
-}
-```
-
-## Security Considerations
-
-### 1. Token Storage
-- Store GitHub access tokens securely (encrypted at rest)
-- Never expose tokens in client-side JavaScript
-- Use secure, HTTP-only cookies for session management
-
-### 2. Token Expiration
-- Monitor `expires_at` field in JWT
-- Refresh tokens before expiration if needed
-- Handle token expiry gracefully
-
-### 3. Rate Limiting
-- GitHub API has rate limits (5,000 requests/hour for authenticated users)
-- Implement caching to reduce API calls
-- Handle rate limit responses (HTTP 429)
-
-## Available GitHub Scopes
-
-The OAuth service requests these scopes:
-- `user:email` - Read user email addresses
-- `read:user` - Read user profile data  
-- `repo` - Access to repositories (full control)
-
-This allows Trackeep instances to:
-- Read repository data
-- Access commit history
-- Monitor pull requests
-- Track branch activity
-
-## API Endpoints
-
-### OAuth Service
-- `GET /auth/github` - Initiate OAuth flow
-- `GET /auth/github/callback` - Handle GitHub callback
-- `GET /api/v1/user/me` - Get current user info
-
-### GitHub API (via access token)
-- `GET /user/repos` - User repositories
-- `GET /repos/{owner}/{repo}/commits` - Repository commits
-- `GET /repos/{owner}/{repo}/pulls` - Pull requests
-- `GET /repos/{owner}/{repo}/branches` - Branches
-- And all other GitHub API endpoints
-
-## Benefits of This Architecture
-
-1. **Separation of Concerns** - OAuth service only handles authentication
-2. **User Privacy** - GitHub data stays in user's Trackeep instance
-3. **Scalability** - Each user instance handles its own GitHub API calls
-4. **Security** - No centralized GitHub data storage
-5. **Flexibility** - Trackeep can implement custom tracking logic
-
