+# EasyStream API Authentication Guide
+
+## Overview
+
+EasyStream now supports modern JWT token-based authentication for API clients, alongside traditional session-based authentication for web pages.
+
+## Authentication Systems
+
+### 1. **Session-Based Authentication** (Traditional Web Pages)
+- Uses PHP sessions with cookies
+- Managed by `VAuth::login()` and `VAuth::logout()`
+- Stored in `db_sessions` table
+- Best for: Traditional server-rendered pages
+
+### 2. **JWT Token Authentication** (Modern APIs)
+- Uses Bearer tokens in Authorization header
+- Managed by `VAuth::loginWithToken()` and `VAuth::validateJWTToken()`
+- Stateless (no server-side session storage)
+- Best for: SPAs, mobile apps, API clients
+
+---
+
+## Backend API Endpoints
+
+### Base URL
+```
+http://localhost:8083/api
+```
+
+### Authentication Endpoints
+
+#### 1. **Login with Token** (New)
+Get a JWT token for API authentication.
+
+**Endpoint:** `POST /auth.php?action=login_token`
+
+**Request Body:**
+```json
+{
+    "identifier": "username or email",
+    "password": "your_password",
+    "expires_in": 86400  // Optional: token expiry in seconds (default: 24 hours)
+}
+```
+
+**Response (Success):**
+```json
+{
+    "success": true,
+    "message": "Login successful",
+    "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
+    "token_type": "Bearer",
+    "expires_in": 86400,
+    "user": {
+        "user_id": 1,
+        "username": "john_doe",
+        "email": "john@example.com",
+        "role": "member"
+    }
+}
+```
+
+**Response (Error):**
+```json
+{
+    "success": false,
+    "message": "Invalid credentials"
+}
+```
+
+---
+
+#### 2. **Verify Token**
+Validate a JWT token and get user information.
+
+**Endpoint:** `GET /auth.php?action=verify_token` or `POST /auth.php?action=verify_token`
+
+**Authorization Header:**
+```
+Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
+```
+
+**Alternative (POST body):**
+```json
+{
+    "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
+}
+```
+
+**Response (Success):**
+```json
+{
+    "success": true,
+    "valid": true,
+    "user": {
+        "user_id": 1,
+        "username": "john_doe",
+        "email": "john@example.com",
+        "role": "member"
+    }
+}
+```
+
+---
+
+#### 3. **Traditional Login** (Session-based)
+For web pages that need PHP session authentication.
+
+**Endpoint:** `POST /auth.php?action=login`
+
+**Request Body:**
+```json
+{
+    "identifier": "username or email",
+    "password": "your_password",
+    "remember_me": false
+}
+```
+
+**Response:**
+```json
+{
+    "success": true,
+    "message": "Login successful",
+    "user": { ... }
+}
+```
+
+*Note: This sets a PHP session cookie, not a JWT token.*
+
+---
+
+## Frontend API Helper Usage
+
+### Include the API Helper
+
+Add to your HTML:
+```html
+<script src="/f_scripts/fe/js/api-helper.js"></script>
+```
+
+### Initialize API Client
+
+```javascript
+// API client is automatically initialized as window.api
+const api = window.api; // or new EasyStreamAPI()
+```
+
+### Authentication Examples
+
+#### Login and Get Token
+```javascript
+try {
+    const result = await api.login('john_doe', 'password123');
+
+    if (result.success) {
+        console.log('Logged in!', result.user);
+        console.log('Token:', result.token);
+        // Token is automatically stored in localStorage
+    }
+} catch (error) {
+    console.error('Login failed:', error.message);
+}
+```
+
+#### Check Authentication Status
+```javascript
+if (api.isAuthenticated()) {
+    console.log('User is authenticated');
+} else {
+    console.log('User is not authenticated');
+}
+```
+
+#### Get Current User Info
+```javascript
+try {
+    const userData = await api.getCurrentUser();
+    console.log('Current user:', userData.user);
+} catch (error) {
+    console.error('Not authenticated:', error);
+}
+```
+
+#### Logout
+```javascript
+try {
+    await api.logout();
+    console.log('Logged out successfully');
+} catch (error) {
+    console.error('Logout error:', error);
+}
+```
+
+---
+
+### Making Authenticated API Requests
+
+The API helper automatically includes the Bearer token in all requests.
+
+#### GET Request
+```javascript
+try {
+    const videos = await api.get('/videos.php', {
+        page: 1,
+        limit: 20,
+        sort: 'newest'
+    });
+
+    console.log('Videos:', videos);
+} catch (error) {
+    console.error('Error:', error);
+}
+```
+
+#### POST Request
+```javascript
+try {
+    const newVideo = await api.post('/videos.php', {
+        title: 'My Awesome Video',
+        description: 'Check this out!',
+        privacy: 'public'
+    });
+
+    console.log('Video created:', newVideo);
+} catch (error) {
+    console.error('Error:', error);
+}
+```
+
+#### PUT Request
+```javascript
+try {
+    const updated = await api.put('/videos.php?id=123', {
+        title: 'Updated Title'
+    });
+
+    console.log('Video updated:', updated);
+} catch (error) {
+    console.error('Error:', error);
+}
+```
+
+#### DELETE Request
+```javascript
+try {
+    const result = await api.delete('/videos.php?id=123');
+    console.log('Video deleted:', result);
+} catch (error) {
+    console.error('Error:', error);
+}
+```
+
+---
+
+## Manual Fetch Example (Without Helper)
+
+If you prefer to use fetch() directly:
+
+```javascript
+// Login and get token
+const loginResponse = await fetch('/api/auth.php?action=login_token', {
+    method: 'POST',
+    headers: {
+        'Content-Type': 'application/json'
+    },
+    body: JSON.stringify({
+        identifier: 'john_doe',
+        password: 'password123'
+    })
+});
+
+const loginData = await loginResponse.json();
+const token = loginData.token;
+
+// Store token
+localStorage.setItem('jwt_token', token);
+
+// Make authenticated request
+const response = await fetch('/api/videos.php', {
+    method: 'GET',
+    headers: {
+        'Authorization': `Bearer ${token}`,
+        'Content-Type': 'application/json'
+    }
+});
+
+const videos = await response.json();
+```
+
+---
+
+## cURL Examples
+
+### Login with Token
+```bash
+curl -X POST http://localhost:8083/api/auth.php?action=login_token \
+  -H "Content-Type: application/json" \
+  -d '{
+    "identifier": "john_doe",
+    "password": "password123"
+  }'
+```
+
+### Verify Token
+```bash
+curl -X GET http://localhost:8083/api/auth.php?action=verify_token \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN_HERE"
+```
+
+### Authenticated API Request
+```bash
+curl -X GET http://localhost:8083/api/videos.php?page=1&limit=10 \
+  -H "Authorization: Bearer YOUR_JWT_TOKEN_HERE"
+```
+
+---
+
+## Token Management
+
+### Token Storage
+- Frontend: Stored in `localStorage` with expiry time
+- Backend: JWT is stateless (no server-side storage)
+
+### Token Expiry
+- Default: 24 hours (86400 seconds)
+- Configurable via `JWT_EXPIRY` in `.env`
+- Client automatically clears expired tokens
+
+### Token Security
+- Secret: Stored in `JWT_SECRET` environment variable
+- Algorithm: HS256 (HMAC-SHA256)
+- Validation: Signature verified on every request
+
+---
+
+## Migration Guide
+
+### For Existing AJAX Code
+
+**Before (jQuery with sessions):**
+```javascript
+$.post('/some_endpoint.php', { action: 'do_something' }, function(data) {
+    console.log(data);
+});
+```
+
+**After (Fetch with JWT):**
+```javascript
+api.post('/some_endpoint.php', { action: 'do_something' })
+    .then(data => console.log(data))
+    .catch(error => console.error(error));
+```
+
+---
+
+## Environment Configuration
+
+Update your `.env` file:
+
+```env
+# JWT Configuration
+JWT_SECRET=9a652ee880c41bafb0a81d38d54b029d63903eeaafccaa8c12880a913931f63b
+JWT_EXPIRY=86400
+
+# CORS Configuration (for separate frontends)
+CORS_ORIGIN=http://localhost:3000
+```
+
+---
+
+## Error Handling
+
+### Common Errors
+
+#### 401 Unauthorized
+```json
+{
+    "success": false,
+    "message": "Invalid or expired token"
+}
+```
+**Solution:** Re-login to get a new token.
+
+#### 403 Forbidden
+```json
+{
+    "success": false,
+    "message": "Access denied"
+}
+```
+**Solution:** User doesn't have permission for this resource.
+
+#### 429 Rate Limited
+```json
+{
+    "success": false,
+    "message": "Too many requests"
+}
+```
+**Solution:** Wait before retrying.
+
+---
+
+## Best Practices
+
+1. **Always use HTTPS in production** - JWT tokens should be transmitted over secure connections
+2. **Store tokens securely** - Use localStorage for web, secure storage for mobile
+3. **Handle token expiry** - Implement token refresh or re-login flow
+4. **Validate on every request** - Backend validates tokens on all protected endpoints
+5. **Clear tokens on logout** - Remove tokens from storage when user logs out
+6. **Use CORS properly** - Configure `Access-Control-Allow-Origin` for your frontend domain

+Authorization: Bearer <token>
+```
+
+---
+
+## Error Handling
+
+All API endpoints return consistent error responses:
+
+```json
+{
+  "success": false,
+  "error": "Error message here",
+  "data": null
+}
+```
+
+### HTTP Status Codes
+
+- `200 OK`: Request successful
+- `400 Bad Request`: Invalid request parameters
+- `401 Unauthorized`: Authentication required or failed
+- `403 Forbidden`: Insufficient permissions
+- `404 Not Found`: Resource not found
+- `405 Method Not Allowed`: HTTP method not supported
+- `429 Too Many Requests`: Rate limit exceeded
+- `500 Internal Server Error`: Server error
+
+---
+
+## Rate Limiting
+
+Rate limits are applied to prevent abuse:
+
+- **Login attempts**: 5 per 15 minutes per IP
+- **Password reset**: 3 per hour per email
+- **API calls**: 100 per minute per user (when authenticated)
+- **Anonymous API calls**: 20 per minute per IP
+
+Rate limit headers:
+
+```
+X-RateLimit-Limit: 100
+X-RateLimit-Remaining: 95
+X-RateLimit-Reset: 1642512000
+```
+
+---
+
+## Frontend Integration
+
+### Using api-helper.js
+
+EasyStream provides a modern JavaScript API client for easy integration:
+
+```javascript
+// Initialize (automatically done on page load)
+const api = window.api; // or new EasyStreamAPI()
+
+// Login
+const loginResult = await api.login('username', 'password');
+if (loginResult.success) {
+  console.log('Logged in!', loginResult.user);
+}
+
+// Get videos
+const videos = await api.getVideos({ page: 1, sort: 'popular' });
+
+// Get single video
+const video = await api.getVideo('123456');
+
+// Like video
+await api.likeVideo('123456', 'like');
+
+// Create comment
+await api.createComment('123456', 'Great video!');
+
+// Subscribe to channel
+await api.subscribe(5);
+
+// Get user profile
+const profile = await api.getUserProfile(123);
+
+// Update profile
+await api.updateProfile({
+  usr_dname: 'New Display Name',
+  usr_about: 'Updated bio'
+});
+
+// Error handling
+try {
+  const result = await api.someAPICall();
+} catch (error) {
+  console.error('API error:', error.message);
+  api.handleError(error);
+}
+```
+
+### Authentication Headers
+
+When using JWT tokens, include the Authorization header:
+
+```javascript
+Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGc...
+```
+
+The api-helper.js automatically handles this for you.
+
+---
+
+## CORS Configuration
+
+Cross-Origin Resource Sharing (CORS) is configured securely:
+
+- **Development**: Allows localhost and 127.0.0.1
+- **Production**: Only allows origins defined in `CORS_ALLOWED_ORIGINS` environment variable
+
+To configure allowed origins in production, set:
+
+```bash
+CORS_ALLOWED_ORIGINS=https://example.com,https://www.example.com
+```
+
+---
+
+## Best Practices
+
+1. **Always use HTTPS** in production
+2. **Store JWT tokens securely** (httpOnly cookies or secure localStorage)
+3. **Include CSRF tokens** for session-based requests
+4. **Handle errors gracefully** and show user-friendly messages
+5. **Implement exponential backoff** for failed requests
+6. **Cache responses** when appropriate
+7. **Validate input** on both client and server side
+8. **Use pagination** for large datasets
+9. **Monitor rate limits** to avoid being throttled
+10. **Log errors** for debugging

+# EasyStream Backend-Frontend Integration Fixes
+
+## Executive Summary
+
+This document outlines the critical fixes applied to resolve backend-frontend disconnection issues in EasyStream and enable modern API-based architecture.
+
+**Date:** 2025-01-28
+**Status:** ✅ Completed
+
+---
+
+## Problems Identified
+
+Through comprehensive analysis using 6 specialized agents, we identified the following critical disconnects:
+
+### 1. **Database Layer Failures** ❌
+- **Issue:** Frontend pages calling non-existent `VDatabase::execute()` method
+- **Impact:** Browse pages, content listings completely broken
+- **Files Affected:** `browse.php:13`, `index_new.php:56-61`
+
+### 2. **Multiple Conflicting Authentication Systems** ❌
+- **Issue:** Three different auth systems (VAuth, VLogin, direct PDO) running simultaneously
+- **Impact:** Session state inconsistency, users appearing logged in on one system but not others
+
+### 3. **Missing API Authentication** ❌
+- **Issue:** No JWT token support for API clients
+- **Impact:** Cannot build decoupled frontends (React, Vue, mobile apps)
+
+### 4. **Configuration Issues** ❌
+- **Issue:** Hardcoded or weak JWT secrets
+- **Impact:** Security vulnerabilities
+
+---
+
+## Solutions Implemented
+
+### ✅ 1. Added VDatabase::execute() Method
+
+**File:** [f_core/f_classes/class.database.php](../f_core/f_classes/class.database.php#L470-L515)
+
+**Changes:**
+```php
+public function execute($sql, $params = [], $cache_time = false)
+{
+    global $db;
+    $rows = [];
+
+    try {
+        // Execute query with or without caching
+        if ($cache_time && is_numeric($cache_time) && $cache_time > 0) {
+            $result = $db->CacheExecute($cache_time, $sql, $params);
+        } else {
+            $result = $db->Execute($sql, $params);
+        }
+
+        // Check for query errors
+        if (!$result) {
+            $logger = VLogger::getInstance();
+            $logger->logDatabaseError($db->ErrorMsg(), $sql, $params);
+            return [];
+        }
+
+        // Convert ADORecordSet to plain array
+        if ($result && !$result->EOF) {
+            while (!$result->EOF) {
+                $rows[] = $result->fields;
+                $result->MoveNext();
+            }
+        }
+
+        return $rows;
+
+    } catch (Exception $e) {
+        $logger = VLogger::getInstance();
+        $logger->logDatabaseError($e->getMessage(), $sql ?? '', $params ?? []);
+        return [];
+    }
+}
+```
+
+**Benefits:**
+- Wraps ADOdb's Execute() method
+- Returns plain PHP arrays (easier for frontend)
+- Includes error logging and exception handling
+- Supports prepared statements
+- Supports query caching
+
+**Status:** ✅ Working - browse.php and index_new.php now functional
+
+---
+
+### ✅ 2. Added JWT Token Authentication to VAuth
+
+**File:** [f_core/f_classes/class.auth.php](../f_core/f_classes/class.auth.php#L760-L960)
+
+**New Methods Added:**
+
+#### `generateJWTToken($user, $expiryTime = null)`
+Generates secure JWT tokens for API authentication.
+
+**Features:**
+- HS256 algorithm (HMAC-SHA256)
+- URL-safe Base64 encoding
+- Configurable expiry time (default: 24 hours)
+- Uses `JWT_SECRET` from environment
+- Includes user_id, username, email, role in payload
+
+#### `validateJWTToken($token)`
+Validates JWT tokens and returns user data.
+
+**Features:**
+- Signature verification
+- Expiry checking
+- User existence validation in database
+- Security event logging
+
+#### `loginWithToken($identifier, $password, $expiryTime = null)`
+Login endpoint that returns JWT token instead of creating session.
+
+**Features:**
+- Validates credentials using existing VAuth::login()
+- Generates and returns JWT token
+- No PHP session created (stateless)
+- Perfect for API clients
+
+#### `authenticateBearer($authHeader = null)`
+Authenticates requests via Authorization: Bearer header.
+
+**Features:**
+- Auto-detects Authorization header
+- Works with Apache mod_rewrite
+- Returns user data or null
+
+**Status:** ✅ Integrated and tested
+
+---
+
+### ✅ 3. Updated API Auth Endpoints
+
+**File:** [api/auth.php](../api/auth.php#L241-L292)
+
+**New Endpoints Added:**
+
+#### `POST /api/auth.php?action=login_token`
+JWT token-based login for API clients.
+
+**Request:**
+```json
+{
+    "identifier": "username or email",
+    "password": "password",
+    "expires_in": 86400  // optional
+}
+```
+
+**Response:**
+```json
+{
+    "success": true,
+    "token": "eyJhbGci...",
+    "token_type": "Bearer",
+    "expires_in": 86400,
+    "user": { ... }
+}
+```
+
+#### `GET/POST /api/auth.php?action=verify_token`
+Verify JWT token validity and get user info.
+
+**Request Header:**
+```
+Authorization: Bearer eyJhbGci...
+```
+
+**Response:**
+```json
+{
+    "success": true,
+    "valid": true,
+    "user": { ... }
+}
+```
+
+**Status:** ✅ Functional and documented
+
+---
+
+### ✅ 4. Secured JWT Configuration
+
+**File:** [.env](../.env#L14-L19)
+
+**Changes:**
+```env
+# Before
+JWT_SECRET=change_this_jwt_secret
+
+# After
+JWT_SECRET=9a652ee880c41bafb0a81d38d54b029d63903eeaafccaa8c12880a913931f63b
+JWT_EXPIRY=86400
+```
+
+**Benefits:**
+- Cryptographically secure secret (64 hex characters)
+- Prevents JWT signature forgery
+- Configurable token expiry
+
+**Status:** ✅ Updated and documented
+
+---
+
+### ✅ 5. Created Modern Frontend API Helper
+
+**File:** [f_scripts/fe/js/api-helper.js](../f_scripts/fe/js/api-helper.js)
+
+**Features:**
+
+#### Token Management
+```javascript
+class EasyStreamAPI {
+    setToken(token, expiresIn)      // Store token in localStorage
+    getStoredToken()                 // Retrieve token
+    clearToken()                     // Remove token
+    isAuthenticated()                // Check auth status
+}
+```
+
+#### Authentication Methods
+```javascript
+await api.login(username, password)        // Login with JWT
+await api.logout()                          // Logout and clear token
+await api.getCurrentUser()                  // Get user info
+await api.verifyToken()                     // Verify token validity
+```
+
+#### HTTP Methods
+```javascript
+await api.get(endpoint, params)            // GET request
+await api.post(endpoint, data)             // POST request
+await api.put(endpoint, data)              // PUT request
+await api.delete(endpoint)                 // DELETE request
+```
+
+**Benefits:**
+- Modern fetch() API (no jQuery dependency)
+- Automatic token injection in headers
+- Token expiry handling
+- LocalStorage persistence
+- Promise-based (async/await support)
+- Error handling and 401 detection
+
+**Usage Example:**
+```javascript
+// Include script
+<script src="/f_scripts/fe/js/api-helper.js"></script>
+
+// Login
+const result = await api.login('john_doe', 'password123');
+if (result.success) {
+    console.log('Logged in!', result.user);
+}
+
+// Make authenticated request
+const videos = await api.get('/videos.php', { page: 1, limit: 20 });
+```
+
+**Status:** ✅ Created and documented
+
+---
+
+### ✅ 6. Comprehensive Documentation
+
+**Files Created:**
+
+1. **[docs/API_AUTHENTICATION_GUIDE.md](../docs/API_AUTHENTICATION_GUIDE.md)**

+
+## Architecture Overview
+
+### Before (Broken)
+```
+Frontend (jQuery)
+  → calls $class_database->execute() [BROKEN]
+  → Traditional sessions only
+  → No API token support
+  → Mixed auth systems
+```
+
+### After (Fixed)
+```
+Frontend (Modern)
+  ├─ Traditional Web Pages
+  │   └─ Session-based auth (VAuth::login)
+  │       └─ PHP sessions + cookies
+  │
+  └─ API Clients (SPAs, Mobile)
+      └─ Token-based auth (VAuth::loginWithToken)
+          └─ JWT Bearer tokens
+              └─ Stored in localStorage
+              └─ Sent via Authorization header
+
+Backend
+  ├─ VDatabase::execute() [FIXED]
+  │   └─ Wraps ADOdb
+  │   └─ Returns arrays
+  │
+  └─ VAuth (Unified)
+      ├─ Session methods (login, logout, isAuthenticated)
+      └─ Token methods (loginWithToken, validateJWTToken)
+```
+
+---
+
+## Testing the Implementation
+
+### 1. Test Database Execution
+
+**Browse Page:**
+```bash
+# Visit: http://localhost:8083/browse.php
+# Should display video list without errors
+```
+
+**Index Page:**
+```bash
+# Visit: http://localhost:8083/index_new.php
+# Should show statistics (video count, user count)
+```
+
+### 2. Test JWT Token Authentication
+
+#### Using cURL:
+
+```bash
+# Login and get token
+curl -X POST http://localhost:8083/api/auth.php?action=login_token \
+  -H "Content-Type: application/json" \
+  -d '{
+    "identifier": "your_username",
+    "password": "your_password"
+  }'
+
+# Response:
+{
+  "success": true,
+  "token": "eyJhbGci...",
+  "token_type": "Bearer",
+  "expires_in": 86400,
+  "user": { ... }
+}
+
+# Verify token
+curl -X GET http://localhost:8083/api/auth.php?action=verify_token \
+  -H "Authorization: Bearer YOUR_TOKEN_HERE"
+
+# Response:
+{
+  "success": true,
+  "valid": true,
+  "user": { ... }
+}
+```
+
+#### Using JavaScript:
+
+```html
+<!DOCTYPE html>
+<html>
+<head>
+    <title>EasyStream API Test</title>
+    <script src="/f_scripts/fe/js/api-helper.js"></script>
+</head>
+<body>
+    <h1>API Test</h1>
+    <button onclick="testLogin()">Test Login</button>
+    <button onclick="testGetVideos()">Test Get Videos</button>
+    <pre id="output"></pre>
+
+    <script>
+        const output = document.getElementById('output');
+
+        async function testLogin() {
+            try {
+                const result = await api.login('your_username', 'your_password');
+                output.textContent = JSON.stringify(result, null, 2);
+
+                if (result.success) {
+                    alert('Login successful! Token stored.');
+                }
+            } catch (error) {
+                output.textContent = 'Error: ' + error.message;
+            }
+        }
+
+        async function testGetVideos() {
+            try {
+                const videos = await api.get('/videos.php', { page: 1, limit: 10 });
+                output.textContent = JSON.stringify(videos, null, 2);
+            } catch (error) {
+                output.textContent = 'Error: ' + error.message;
+            }
+        }
+    </script>
+</body>
+</html>
+```
+
+### 3. Test Browser Console
+
+```javascript
+// Open browser console on any EasyStream page with api-helper.js loaded
+
+// Login
+await api.login('username', 'password');
+
+// Check if authenticated
+console.log(api.isAuthenticated()); // true
+
+// Get current user
+const user = await api.getCurrentUser();
+console.log(user);
+
+// Logout
+await api.logout();
+console.log(api.isAuthenticated()); // false
+```
+
+---
+
+## Remaining Issues (Not Critical)
+
+### 1. Multiple Caddyfile Configurations
+**Status:** ⚠️ Minor issue
+**Impact:** Confusion about which config is active
+**Recommendation:** Consolidate to single Caddyfile
+
+**Files:**
+- `Caddyfile` (active)
+- `Caddyfile.updated`
+- `Caddyfile.backup`
+- `Caddyfile.livestream`
+
+### 2. Missing CORS for Main Pages
+**Status:** ⚠️ Minor issue
+**Impact:** Cross-origin requests from separate frontends may fail
+**Current:** API endpoints have CORS, main pages don't
+**Recommendation:** Add CORS middleware if building separate frontend
+
+### 3. Legacy VLogin Class Still Exists
+**Status:** ℹ️ Informational
+**Impact:** None (not used by new code)
+**Recommendation:** Gradually migrate old code to VAuth
+
+---
+
+## Migration Path for Existing Code
+
+### Step 1: Update Frontend AJAX to Use API Helper
+
+**Before (jQuery):**
+```javascript
+$.post('/some_action.php', { data: value }, function(response) {
+    console.log(response);
+});
+```
+
+**After (Modern):**
+```javascript
+api.post('/some_action.php', { data: value })
+    .then(response => console.log(response))
+    .catch(error => console.error(error));
+```
+
+### Step 2: Update Backend Endpoints to Support JWT
+
+**Add to your endpoint file:**
+```php
+<?php
+define('_ISVALID', true);
+require_once '../f_core/config.core.php';
+
+// Initialize auth
+$auth = VAuth::getInstance();
+
+// Check for Bearer token
+$user = $auth->authenticateBearer();
+
+if (!$user) {
+    // Not authenticated
+    http_response_code(401);
+    echo json_encode(['success' => false, 'message' => 'Authentication required']);
+    exit;
+}
+
+// User is authenticated, proceed with logic
+$userId = $user['user_id'];
+$username = $user['username'];
+// ... your code here
+```
+
+---
+
+## Security Considerations
+
+### ✅ Implemented
+- Secure JWT secret (64 hex characters)
+- HS256 signature algorithm
+- Token expiry validation
+- Signature verification on every request
+- Security event logging
+- Rate limiting (via VAuth)
+- User existence validation
+
+### 🔒 Recommendations for Production
+
+1. **Use HTTPS Only**
+   - JWT tokens should never be sent over HTTP
+   - Update MAIN_URL in .env to use https://
+
+2. **Rotate JWT Secret Periodically**
+   - Generate new secret every 90 days
+   - Use: `openssl rand -hex 32`
+
+3. **Implement Token Refresh**
+   - Add refresh token endpoint
+   - Short-lived access tokens (1 hour)
+   - Long-lived refresh tokens (30 days)
+
+4. **Add Rate Limiting**
+   - Already implemented in VAuth
+   - Configure limits in VSecurity class
+
+5. **Monitor Security Events**
+   - Check logs in `f_data/logs/`
+   - Watch for failed login attempts
+   - Alert on unusual patterns
+
+---
+
+## Performance Impact
+
+### Database Queries
+- **Before:** Failed queries (method didn't exist)
+- **After:** ✅ Working queries with caching support
+- **Impact:** Positive - pages now load correctly
+
+### Authentication
+- **Session-based:** Similar performance (unchanged)
+- **JWT-based:** Faster (no session lookup in database)
+- **Impact:** Neutral to positive
+
+### Frontend
+- **Old:** jQuery dependency, callback hell
+- **New:** Modern fetch(), async/await, no extra dependencies
+- **Impact:** Positive - cleaner code, better maintainability
+
+---
+
+## Next Steps
+
+### Immediate (Required)
+1. ✅ Test browse.php and index_new.php
+2. ✅ Test JWT login via API
+3. ✅ Verify token authentication works
+4. ⏳ Deploy to staging environment
+
+### Short Term (Recommended)
+1. ⏳ Add token refresh endpoint
+2. ⏳ Migrate remaining jQuery AJAX to fetch()
+3. ⏳ Add API endpoints for all resources
+4. ⏳ Update Caddyfile with API routes and CORS
+
+### Long Term (Optional)
+1. ⏳ Build React/Vue frontend using JWT auth
+2. ⏳ Create mobile apps using JWT auth
+3. ⏳ Add OAuth2 support (Google, Facebook login)
+4. ⏳ Implement WebSockets for real-time features
+
+---
+
+## Troubleshooting
+
+### Issue: "Invalid JWT format"
+**Cause:** Token not properly formatted
+**Solution:** Ensure token has 3 parts separated by dots: `header.payload.signature`
+
+### Issue: "JWT signature verification failed"
+**Cause:** JWT_SECRET mismatch between token generation and validation
+**Solution:** Check JWT_SECRET in .env is correct and consistent
+
+### Issue: "JWT token expired"
+**Cause:** Token lifetime exceeded
+**Solution:** Login again to get new token, or implement token refresh
+
+### Issue: "Not authenticated" on API call
+**Cause:** Missing or invalid Authorization header
+**Solution:** Ensure header format is: `Authorization: Bearer YOUR_TOKEN`
+
+### Issue: "VDatabase::execute() not found"
+**Cause:** Old class file cached
+**Solution:** Restart PHP-FPM: `docker-compose restart php`
+
+### Issue: CORS errors from browser
+**Cause:** Missing Access-Control headers
+**Solution:** API endpoints have CORS. For other pages, add headers in Caddyfile

+**JW Player Branding Migration**
+
+- Purpose: replace legacy ViewShark branding inside the JW Player serialized config stored in `db_fileplayers`.
+- What it changes:
+  - `jw_logo_file` → empty (no external logo by default)
+  - `jw_logo_link` → your `site_url` (if set), otherwise empty
+  - `jw_rc_text` → `Powered by EasyStream` (uses your `site_name` if present)
+  - `jw_rc_link` → your `site_url` (if set), otherwise empty
+
+Run after your database is initialized (docker-compose up created the schema):
+
+- `php f_scripts/migrations/update_jw_branding.php`
+
+Notes
+- The script safely unserializes the PHP array, updates keys, and reserializes.
+- It only touches `db_name` in (`jw_local`, `jw_embed`).
+- If no change is necessary, it leaves rows untouched.

+## 1. Session Variable Conflicts
+
+### Problem
+
+Multiple session variable names are used inconsistently:
+- `$_SESSION['USER_ID']` (uppercase)
+- `$_SESSION['usr_id']` (lowercase)
+- `$_SESSION['user_id']` (lowercase with underscore)
+
+This causes bugs where authentication checks fail randomly.
+
+### Current Impact
+
+**Files affected:** 26+ files
+
+**Example conflicts:**
+```php
+// api/videos.php - Checks both!
+if (!$userId && isset($_SESSION['USER_ID'])) {
+    $userId = $_SESSION['USER_ID'];
+} elseif (!$userId && isset($_SESSION['usr_id'])) {
+    $userId = $_SESSION['usr_id'];
+}
+
+// f_modules/m_frontend/m_acct/account.php - Uses different one
+$membership_check = ($_SESSION["USER_ID"] > 0) ? VLogin::checkSubscription() : null;
+```
+
+### Solution
+
+**Standardize on ONE session variable: `$_SESSION['USER_ID']`**
+
+#### Step 1: Create Session Helper Function
+
+**File:** `f_core/f_functions/functions.session.php`
+
+```php
+<?php
+/**
+ * Session Helper Functions
+ * Provides standardized session access
+ */
+
+/**
+ * Get current user ID from session
+ * Handles legacy session variable names
+ *
+ * @return int User ID or 0 if not logged in
+ */
+function getCurrentUserId() {
+    // Check modern standard
+    if (isset($_SESSION['USER_ID']) && $_SESSION['USER_ID'] > 0) {
+        return (int) $_SESSION['USER_ID'];
+    }
+
+    // Check legacy variants (for migration period)
+    if (isset($_SESSION['usr_id']) && $_SESSION['usr_id'] > 0) {
+        // Migrate to new standard
+        $_SESSION['USER_ID'] = (int) $_SESSION['usr_id'];
+        unset($_SESSION['usr_id']);
+        return (int) $_SESSION['USER_ID'];
+    }
+
+    if (isset($_SESSION['user_id']) && $_SESSION['user_id'] > 0) {
+        // Migrate to new standard
+        $_SESSION['USER_ID'] = (int) $_SESSION['user_id'];
+        unset($_SESSION['user_id']);
+        return (int) $_SESSION['USER_ID'];
+    }
+
+    return 0;
+}
+
+/**
+ * Set current user ID in session
+ *
+ * @param int $userId User ID to set
+ */
+function setCurrentUserId($userId) {
+    $_SESSION['USER_ID'] = (int) $userId;
+
+    // Clean up legacy session variables
+    unset($_SESSION['usr_id']);
+    unset($_SESSION['user_id']);
+}
+
+/**
+ * Check if user is logged in
+ *
+ * @return bool
+ */
+function isUserLoggedIn() {
+    return getCurrentUserId() > 0;
+}
+
+/**
+ * Clear user session
+ */
+function clearUserSession() {
+    unset($_SESSION['USER_ID']);
+    unset($_SESSION['usr_id']);
+    unset($_SESSION['user_id']);
+}
+```
+
+#### Step 2: Update VAuth to Use Standard
+
+**File:** `f_core/f_classes/class.auth.php`
+
+Add to VAuth class:
+
+```php
+/**
+ * Get current user ID
+ * @return int
+ */
+public static function getCurrentUserId() {
+    return getCurrentUserId(); // Use helper function
+}
+
+/**
+ * Set user ID after login
+ * @param int $userId
+ */
+private function setUserId($userId) {
+    setCurrentUserId($userId);
+}
+```
+
+#### Step 3: Update All API Endpoints
+
+Replace this pattern:
+```php
+// OLD - checking multiple variables
+if (!$userId && isset($_SESSION['USER_ID'])) {
+    $userId = $_SESSION['USER_ID'];
+} elseif (!$userId && isset($_SESSION['usr_id'])) {
+    $userId = $_SESSION['usr_id'];
+}
+```
+
+With:
+```php
+// NEW - use helper function
+if (!$userId) {
+    $userId = getCurrentUserId();
+}
+```
+
+#### Step 4: Update All Module Files
+
+**Files to update:**
+- `f_modules/m_frontend/m_acct/account.php`
+- `f_modules/m_frontend/templatebuilder.php`
+- `f_modules/m_frontend/templatebuilder_ajax.php`
+- `f_modules/m_frontend/m_player/embed.php`
+- `f_modules/m_frontend/m_notif/notifications_bell.php`
+
+**Before:**
+```php
+$user_id = isset($_SESSION['USER_ID']) ? (int)$_SESSION['USER_ID'] : 0;
+```
+
+**After:**
+```php
+$user_id = getCurrentUserId();
+```
+
+---
+
+## 2. Authentication Class Conflicts
+
+### Problem
+
+**Multiple authentication classes exist:**
+1. `VLogin` - Old, deprecated, still referenced in `account.php`
+2. `VSession` - Redundant with VAuth
+3. `VAuth` - Modern, should be the only one used
+
+### Current Impact
+
+**File:** `f_modules/m_frontend/m_acct/account.php`
+
+```php
+// Line 37 - Uses OLD VLogin class!
+$membership_check = ($_SESSION["USER_ID"] > 0) ? VLogin::checkSubscription() : null;
+```
+
+This will FAIL if VLogin class is removed.
+
+### Solution
+
+#### Step 1: Check if VLogin Class Exists
+
+```bash
+find . -name "class.login.php" -type f
+```
+
+**Result:** No `class.login.php` found - VLogin doesn't exist!
+
+This means `account.php` line 37 will throw a fatal error.
+
+#### Step 2: Fix account.php
+
+**File:** `f_modules/m_frontend/m_acct/account.php`
+
+**Before:**
+```php
+$membership_check = ($cfg["paid_memberships"] == 1 and $_SESSION["USER_ID"] > 0)
+    ? VLogin::checkSubscription()
+    : null;
+```
+
+**After:**
+```php
+// Use VAuth or VMembership class instead
+require_once $cfg['classes_dir'] . '/class.membership.php';
+
+$membership_check = ($cfg["paid_memberships"] == 1 && getCurrentUserId() > 0)
+    ? VMembership::checkSubscription(getCurrentUserId())
+    : null;
+```
+
+#### Step 3: Search and Replace All VLogin References
+
+```bash
+# Find all VLogin references
+grep -r "VLogin" --include="*.php" f_modules/
+
+# Replace with VAuth
+# For each file found, update to use VAuth::getInstance()
+```
+
+---
+
+## 3. Database Query Conflicts
+
+### Problem
+
+**Multiple patterns for database queries:**
+
+1. **Old direct ADOdb calls:**
+```php
+$db = $database->db_connect();
+$result = $db->Execute("SELECT ...");
+```
+
+2. **VDatabase wrapper (correct):**
+```php
+$db = VDatabase::getInstance();
+$result = $db->execute("SELECT ...", $params);
+```
+
+3. **Old procedural style:**
+```php
+$result = mysql_query("SELECT ...");
+```
+
+### Solution
+
+**Standardize on VDatabase singleton pattern**
+
+#### Search and Replace Pattern
+
+**Find:**
+```php
+$database->db_connect()
+$db->Execute()
+$db->GetRow()
+```
+
+**Replace with:**
+```php
+$db = VDatabase::getInstance();
+$db->execute()
+$db->singleRow()
+```
+
+#### Example Fix
+
+**Before:**
+```php
+function getUser($userId) {
+    global $database;
+    $db = $database->db_connect();
+    $sql = "SELECT * FROM db_users WHERE usr_id = " . $userId; // SQL injection!
+    $result = $db->Execute($sql);
+    return $result->FetchRow();
+}
+```
+
+**After:**
+```php
+function getUser($userId) {
+    $db = VDatabase::getInstance();
+    $sql = "SELECT * FROM db_users WHERE usr_id = ?";
+    $result = $db->execute($sql, [$userId]);
+    return $result && $result->RecordCount() > 0 ? $result->fields : null;
+}
+```
+
+---
+
+## 4. Frontend JavaScript Conflicts
+
+### Problem
+
+**Three different AJAX patterns:**
+
+1. **jQuery $.post (legacy):**
+```javascript
+jQuery.post(url, data, function(result) { ... });
+```
+
+2. **jQuery $.ajax (legacy):**
+```javascript
+jQuery.ajax({ url: url, method: 'POST', data: data });
+```
+
+3. **Modern fetch via api-helper (new):**
+```javascript
+await api.post(url, data);
+```
+
+### Current Impact
+
+- **Page weight:** jQuery adds 87KB
+- **Maintenance:** Three patterns to maintain
+- **Consistency:** Different error handling for each
+
+### Solution
+
+**Migrate all to api-helper.js**
+
+#### Migration Example 1: Browse Videos
+
+**File:** `f_scripts/fe/js/browse.init.js`
+
+**Before:**
+```javascript
+jQuery(".more-button").click(function () {
+    var page = parseInt(jQuery(this).attr("rel-page"));
+    var url = _rel + "?p=0&m=" + idnr + "&sort=" + type + "&page=" + page;
+
+    jQuery("#list ul").mask("");
+
+    jQuery.get(url, function(result) {
+        jQuery("#list ul").append(result).unmask();
+        jQuery(".more-button").attr("rel-page", page + 1);
+    });
+});
+```
+
+**After:**
+```javascript
+document.addEventListener('click', async (e) => {
+    const moreBtn = e.target.closest('.more-button');
+    if (!moreBtn) return;
+
+    const page = parseInt(moreBtn.dataset.page);
+
+    try {
+        showLoading(moreBtn);
+
+        const result = await api.getVideos({
+            page: page,
+            sort: currentSort,
+            category: currentCategory
+        });
+
+        if (result.success) {
+            appendVideos(result.data.videos);
+            moreBtn.dataset.page = page + 1;
+
+            // Hide button if no more pages
+            if (page >= result.data.pagination.pages) {
+                moreBtn.style.display = 'none';
+            }
+        }
+    } catch (error) {
+        api.handleError(error);
+    } finally {
+        hideLoading(moreBtn);
+    }
+});
+
+function appendVideos(videos) {
+    const list = document.getElementById('video-list');
+    videos.forEach(video => {
+        const item = createVideoElement(video);
+        list.appendChild(item);
+    });
+}
+```
+
+#### Migration Example 2: Watch Later
+
+**File:** `f_scripts/fe/js/browse.init.js`
+
+**Before:**
+```javascript
+jQuery(".watch_later_wrap").click(function () {
+    var file_key = jQuery(this).attr("rel-key");
+    var _this = jQuery(this);
+
+    jQuery.post(url, {"fileid[0]": file_key}, function(result) {
+        _this.find(".icon-clock")
+            .removeClass("icon-clock")
+            .addClass("icon-check");
+    });
+});
+```
+
+**After:**
+```javascript
+document.addEventListener('click', async (e) => {
+    const watchBtn = e.target.closest('.watch-later-btn');
+    if (!watchBtn) return;
+
+    const fileKey = watchBtn.dataset.fileKey;
+
+    try {
+        const result = await api.toggleWatchLater(fileKey);
+
+        if (result.success) {
+            const icon = watchBtn.querySelector('.icon');
+
+            if (result.data.action === 'added') {
+                icon.classList.remove('icon-clock');
+                icon.classList.add('icon-check');
+                watchBtn.title = 'In Watch List';
+            } else {
+                icon.classList.remove('icon-check');
+                icon.classList.add('icon-clock');
+                watchBtn.title = 'Watch Later';
+            }
+        }
+    } catch (error) {
+        api.handleError(error);
+    }
+});
+```
+
+---
+
+## 5. API Response Format Conflicts
+
+### Problem
+
+**Inconsistent response formats:**
+
+1. **New API endpoints (standardized):**
+```json
+{
+  "success": true,
+  "data": { ... },
+  "error": null
+}
+```
+
+2. **Old endpoints (inconsistent):**
+```json
+{
+  "status": "ok",
+  "result": { ... }
+}
+```
+
+OR just raw data:
+```json
+{ "usr_id": 1, "usr_name": "john" }
+```
+
+### Solution
+
+**Update all old endpoints to use standard format**
+
+#### Standard Response Helper
+
+**File:** `f_core/f_functions/functions.api.php`
+
+```php
+<?php
+/**
+ * API Response Functions
+ * Provides standardized API responses
+ */
+
+/**
+ * Send success response
+ *
+ * @param mixed $data Data to return
+ * @param int $statusCode HTTP status code
+ */
+function sendApiSuccess($data = null, $statusCode = 200) {
+    http_response_code($statusCode);
+    header('Content-Type: application/json');
+
+    echo json_encode([
+        'success' => true,
+        'data' => $data,
+        'error' => null
+    ], JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
+
+    exit;
+}
+
+/**
+ * Send error response
+ *
+ * @param string $message Error message
+ * @param int $statusCode HTTP status code
+ * @param array $details Additional error details
+ */
+function sendApiError($message, $statusCode = 400, $details = null) {
+    http_response_code($statusCode);
+    header('Content-Type: application/json');
+
+    $response = [
+        'success' => false,
+        'data' => null,
+        'error' => $message
+    ];
+
+    if ($details) {
+        $response['details'] = $details;
+    }
+
+    echo json_encode($response, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
+
+    exit;
+}
+
+/**
+ * Validate API request method
+ *
+ * @param string|array $allowedMethods Allowed HTTP method(s)
+ * @throws Exception if method not allowed
+ */
+function validateApiMethod($allowedMethods) {
+    $allowedMethods = (array) $allowedMethods;
+    $currentMethod = $_SERVER['REQUEST_METHOD'];
+
+    if (!in_array($currentMethod, $allowedMethods)) {
+        sendApiError(
+            'Method not allowed. Allowed: ' . implode(', ', $allowedMethods),
+            405
+        );
+    }
+}
+```
+
+#### Update Old API Endpoints
+
+**Example:** `api/privacy.php`
+
+**Before:**
+```php
+// Returns raw data, no standard format
+echo json_encode($result);
+```
+
+**After:**
+```php
+require_once __DIR__ . '/../f_core/f_functions/functions.api.php';
+
+try {
+    // ... existing code ...
+
+    sendApiSuccess([
+        'privacy_settings' => $result
+    ]);
+
+} catch (Exception $e) {
+    sendApiError($e->getMessage(), 500);
+}
+```
+
+---
+
+## 6. Migration Action Plan
+
+### Critical Fixes (Do First - High Impact)
+
+#### Fix 1: Create Session Helper Functions
+
+**File to create:** `f_core/f_functions/functions.session.php`
+
+**Priority:** CRITICAL - Affects authentication everywhere
+
+**Time:** 30 minutes
+
+**Steps:**
+1. Create the file with helper functions (code provided above)
+2. Include in `f_core/config.core.php`
+3. Test that `getCurrentUserId()` works
+
+**Test:**
+```php
+// Add to any page temporarily
+echo "User ID: " . getCurrentUserId();
+```
+
+#### Fix 2: Update API Endpoints to Use Helper
+
+**Files to update:**
+- `api/videos.php`
+- `api/user.php`
+- `api/comments.php`
+- `api/subscriptions.php`
+
+**Priority:** HIGH - Prevents session bugs
+
+**Time:** 1 hour
+
+**Pattern to replace:**
+```php
+// Find this:
+if (!$userId && isset($_SESSION['USER_ID'])) {
+    $userId = $_SESSION['USER_ID'];
+} elseif (!$userId && isset($_SESSION['usr_id'])) {
+    $userId = $_SESSION['usr_id'];
+}
+
+// Replace with:
+if (!$userId) {
+    $userId = getCurrentUserId();
+}
+```
+
+#### Fix 3: Fix VLogin Reference in account.php
+
+**File:** `f_modules/m_frontend/m_acct/account.php`
+
+**Priority:** CRITICAL - Currently broken!
+
+**Time:** 15 minutes
+
+**Line 37 fix:**
+```php
+// Before:
+$membership_check = ($_SESSION["USER_ID"] > 0) ? VLogin::checkSubscription() : null;
+
+// After:
+$membership_check = ($cfg["paid_memberships"] == 1 && getCurrentUserId() > 0)
+    ? VMembership::checkSubscription(getCurrentUserId())
+    : null;
+```
+
+### Medium Priority Fixes
+
+#### Fix 4: Standardize Database Queries
+
+**Pattern:** Search for `$database->db_connect()` and replace with `VDatabase::getInstance()`
+
+**Priority:** MEDIUM - Performance improvement
+
+**Time:** 2-3 hours
+
+**Command:**
+```bash
+grep -r "db_connect" --include="*.php" f_modules/
+```
+
+#### Fix 5: Migrate jQuery AJAX in browse.init.js
+
+**File:** `f_scripts/fe/js/browse.init.js`
+
+**Priority:** MEDIUM - Performance improvement
+
+**Time:** 3-4 hours
+
+**See examples in section 4 above**
+
+### Low Priority (Can wait)
+
+#### Fix 6: Create API Response Helper
+
+**File to create:** `f_core/f_functions/functions.api.php`
+
+**Priority:** LOW - Nice to have
+
+**Time:** 1 hour
+
+#### Fix 7: Update Old API Endpoints
+
+**Files:** `api/privacy.php`, `api/telegram.php`, etc.
+
+**Priority:** LOW - These endpoints still work
+
+**Time:** 2-3 hours
+
+---
+

+## Rollback Plan
+
+If something breaks:
+
+1. **Backup before changes:**
+```bash
+git add .
+git commit -m "Before conflict resolution"
+```
+
+2. **If issues occur:**
+```bash
+git revert HEAD
+```
+
+3. **Test specific fix in isolation:**
+```bash
+git checkout -b test-session-fix
+# Apply only session fix
+# Test thoroughly
+# If good, merge to main
+```
+
+---
+
+## Priority Order
+
+1. ✅ **Session Helper Functions** - Do this FIRST (CRITICAL)
+2. ✅ **Update API Endpoints** - Fix session access (HIGH)
+3. ✅ **Fix account.php VLogin** - Currently broken (CRITICAL)
+4. ⏸️ **Standardize Database Queries** - Performance (MEDIUM)
+5. ⏸️ **Migrate jQuery AJAX** - Performance (MEDIUM)
+6. ⏸️ **API Response Helpers** - Nice to have (LOW)
+
+---
+
+## Estimated Timeline
+
+- **Critical fixes (1-3):** 2-3 hours
+- **Medium fixes (4-5):** 1 week
+- **Low priority (6-7):** 1-2 weeks
+
+**Total: 2-3 weeks for complete resolution**
+
+---
+
+## Next Steps
+
+1. Create `f_core/f_functions/functions.session.php`
+2. Update `f_core/config.core.php` to include it
+3. Update all API endpoints to use `getCurrentUserId()`
+4. Fix `f_modules/m_frontend/m_acct/account.php`
+5. Test authentication thoroughly
+6. Proceed to medium priority fixes

+
+---
+
+## Architecture Overview
+
+### Current State
+
+EasyStream has three layers of API integration:
+
+1. **Modern API Endpoints** (`/api/*.php`)
+   - RESTful design
+   - JSON request/response
+   - JWT + Session auth support
+   - Proper error handling
+
+2. **Modern Frontend Client** (`api-helper.js`)
+   - Fetch API based
+   - Promise/async-await pattern
+   - Automatic token management
+   - Error handling helpers
+
+3. **Legacy Frontend Code** (jQuery AJAX calls)
+   - Scattered across multiple files
+   - Inconsistent patterns
+   - Needs migration
+
+### Target State
+
+All frontend code should use `api-helper.js` for consistency, maintainability, and better error handling.
+
+---
+
+## Migration Strategy
+
+### Phase 1: Identify Legacy Code (COMPLETED)
+
+Found legacy jQuery AJAX calls in:
+- `f_scripts/fe/js/browse.init.js`
+- `f_scripts/fe/js/jquery.init.js`
+- Various other frontend scripts
+
+### Phase 2: Create Modern API Endpoints (COMPLETED)
+
+Created comprehensive RESTful APIs:
+- `/api/videos.php` - Video operations
+- `/api/user.php` - User profile operations
+- `/api/comments.php` - Comment operations
+- `/api/subscriptions.php` - Subscription operations
+- `/api/auth.php` - Authentication (already existed, enhanced)
+
+### Phase 3: Enhance Frontend Client (COMPLETED)
+
+Enhanced `api-helper.js` with methods for all endpoints.
+
+### Phase 4: Migrate Legacy Code (IN PROGRESS)
+
+Replace jQuery AJAX calls with modern fetch API using `api-helper.js`.
+
+### Phase 5: Test & Validate (PENDING)
+
+Test all integrated endpoints end-to-end.
+
+---
+
+## Using api-helper.js
+
+### Basic Setup
+
+The API helper is automatically initialized on page load:
+
+```javascript
+// Available globally
+const api = window.api;
+
+// Or create new instance
+const customAPI = new EasyStreamAPI('/api');
+```
+
+### Authentication
+
+#### Login
+
+```javascript
+// Login and store token
+try {
+  const result = await api.login('username', 'password');
+  if (result.success) {
+    console.log('Logged in as:', result.user.usr_user);
+    // Token is automatically stored in localStorage
+  }
+} catch (error) {
+  console.error('Login failed:', error.message);
+}
+```
+
+#### Check Authentication
+
+```javascript
+if (api.isAuthenticated()) {
+  console.log('User is logged in');
+} else {
+  console.log('User needs to login');
+}
+```
+
+#### Logout
+
+```javascript
+await api.logout();
+// Token is automatically cleared
+```
+
+### Making API Calls
+
+#### Videos
+
+```javascript
+// List videos
+const videos = await api.getVideos({
+  page: 1,
+  limit: 20,
+  sort: 'popular',
+  category: 'entertainment'
+});
+
+// Get single video
+const video = await api.getVideo('123456');
+
+// Search videos
+const searchResults = await api.searchVideos('search query', { page: 1 });
+
+// Create video
+const newVideo = await api.createVideo({
+  title: 'My Video',
+  description: 'Video description',
+  privacy: 'public'
+});
+
+// Update video
+await api.updateVideo('123456', {
+  file_title: 'Updated Title'
+});
+
+// Delete video
+await api.deleteVideo('123456');
+
+// Like video
+await api.likeVideo('123456', 'like');
+
+// Record view
+await api.recordVideoView('123456');
+
+// Watch later
+await api.toggleWatchLater('123456');
+```
+
+#### User Profile
+
+```javascript
+// Get current user's profile
+const myProfile = await api.getMyProfile();
+
+// Get another user's profile
+const userProfile = await api.getUserProfile(123);
+
+// Update profile
+await api.updateProfile({
+  usr_dname: 'New Name',
+  usr_about: 'Updated bio'
+});
+
+// Upload avatar
+const fileInput = document.getElementById('avatar-input');
+const file = fileInput.files[0];
+await api.uploadAvatar(file);
+
+// Get user stats
+const stats = await api.getUserStats();
+
+// Get user's videos
+const userVideos = await api.getUserVideos(123, { page: 1 });
+```
+
+#### Comments
+
+```javascript
+// Get comments
+const comments = await api.getComments('123456', {
+  page: 1,
+  sort: 'recent'
+});
+
+// Create comment
+const newComment = await api.createComment(
+  '123456', // file_key
+  'This is my comment',
+  null // parent_id (null for top-level comment)
+);
+
+// Reply to comment
+const reply = await api.createComment(
+  '123456',
+  'This is a reply',
+  456 // parent comment ID
+);
+
+// Update comment
+await api.updateComment(789, 'Updated text');
+
+// Delete comment
+await api.deleteComment(789);
+
+// Like comment
+await api.likeComment(789);
+
+// Report comment
+await api.reportComment(789, 'Spam');
+```
+
+#### Subscriptions
+
+```javascript
+// Get subscriptions
+const subs = await api.getSubscriptions();
+
+// Check if subscribed
+const status = await api.checkSubscription(123);
+if (status.data.is_subscribed) {
+  console.log('Already subscribed');
+}
+
+// Subscribe
+await api.subscribe(123);
+
+// Unsubscribe
+await api.unsubscribe(123);
+
+// Get subscription feed
+const feed = await api.getSubscriptionFeed({ page: 1 });
+
+// Get subscribers
+const subscribers = await api.getSubscribers(123);
+```
+
+---
+
+## Authentication Patterns
+
+### JWT Token Authentication (Recommended)
+
+Best for: SPAs, mobile apps, API clients
+
+```javascript
+// 1. Login to get token
+const result = await api.login('username', 'password');
+
+// 2. Token is automatically stored and used for subsequent requests
+const profile = await api.getMyProfile();
+
+// 3. Logout clears token
+await api.logout();
+```
+
+### Session-based Authentication
+
+Best for: Traditional multi-page websites
+
+```javascript
+// Login via form submission (handles CSRF automatically)
+const formData = new FormData(loginForm);
+const response = await fetch('/api/auth.php?action=login', {
+  method: 'POST',
+  body: formData,
+  credentials: 'include' // Important for cookies
+});
+```
+
+### Hybrid Approach
+
+Use sessions for page navigation, JWT for API calls:
+
+```javascript
+// Check if user has session
+const statusResponse = await fetch('/api/auth.php?action=status', {
+  credentials: 'include'
+});
+const status = await statusResponse.json();
+
+if (status.authenticated) {
+  // User has session, optionally get JWT for API calls
+  // (if needed for cross-origin requests)
+}
+```
+
+---
+
+## Common Migration Patterns
+
+### Pattern 1: Simple GET Request
+
+**Before (jQuery):**
+```javascript
+jQuery.get(url, function(result) {
+  console.log(result);
+  updateUI(result);
+});
+```
+
+**After (api-helper):**
+```javascript
+try {
+  const result = await api.get(url);
+  console.log(result);
+  updateUI(result.data);
+} catch (error) {
+  api.handleError(error);
+}
+```
+
+### Pattern 2: POST with Data
+
+**Before (jQuery):**
+```javascript

+}, function(result) {
+  if (result.success) {
+    showSuccess('Saved!');
+  }
+});
+```
+
+**After (api-helper):**
+```javascript
+try {
+  const result = await api.post(url, {
+    field1: value1,

+  var url = _rel + "?p=0&m=" + idnr + "&sort=" + type + "&page=" + page;
+
+  jQuery.get(url, function(result) {
+    jQuery("#list ul").append(result);
+    jQuery(".more-button").attr("rel-page", page + 1);
+  });
+});
+```
+
+**After (api-helper):**
+```javascript
+document.addEventListener('click', async (e) => {
+  if (e.target.classList.contains('more-button')) {
+    const page = parseInt(e.target.getAttribute('data-page'));
+
+    try {
+      const result = await api.getVideos({
+        page: page,
+        sort: currentSort,
+        category: currentCategory
+      });
+
+      if (result.success) {
+        appendVideos(result.data.videos);
+        e.target.setAttribute('data-page', page + 1);
+
+        // Hide button if no more pages
+        if (page >= result.data.pagination.pages) {
+          e.target.style.display = 'none';
+        }
+      }
+    } catch (error) {
+      api.handleError(error);
+    }
+  }
+});
+
+function appendVideos(videos) {
+  const list = document.getElementById('video-list');
+  videos.forEach(video => {
+    const item = createVideoElement(video);
+    list.appendChild(item);
+  });
+}
+```
+
+### Pattern 4: Form Submission
+
+**Before (jQuery):**
+```javascript
+jQuery("#comment-form").submit(function(e) {

+    if (result.success) {
+      addCommentToUI(result.comment);
+      jQuery("#comment-form")[0].reset();
+    }
+  });
+});
+```
+
+**After (api-helper):**
+```javascript
+document.getElementById('comment-form').addEventListener('submit', async (e) => {
+  e.preventDefault();
+
+  const formData = new FormData(e.target);

+  const fileKey = formData.get('file_key');
+
+  try {
+    const result = await api.createComment(fileKey, commentText);
+
+    if (result.success) {
+      addCommentToUI(result.data);
+      e.target.reset();
+    }
+  } catch (error) {
+    api.handleError(error);
+  }
+});
+```
+
+### Pattern 5: Watch Later Toggle
+
+**Before (jQuery):**
+```javascript
+jQuery(".watch_later_wrap").click(function() {
+  var file_key = jQuery(this).attr("rel-key");
+  var file_type = jQuery(this).attr("rel-type");
+  var url = _rel + "?a=cb-watchadd&for=sort-" + file_type;
+  var _this = jQuery(this);
+
+  jQuery.post(url, {"fileid[0]": file_key}, function(result) {
+    _this.find(".icon-clock")
+      .removeClass("icon-clock")
+      .addClass("icon-check");
+    _this.next().text("In Watch List");
+  });
+});
+```
+
+**After (api-helper):**
+```javascript
+document.addEventListener('click', async (e) => {
+  const watchBtn = e.target.closest('.watch-later-btn');
+  if (!watchBtn) return;
+
+  const fileKey = watchBtn.dataset.fileKey;
+
+  try {
+    const result = await api.toggleWatchLater(fileKey);
+
+    if (result.success) {
+      const icon = watchBtn.querySelector('.icon');
+      const text = watchBtn.querySelector('.text');
+
+      if (result.data.action === 'added') {
+        icon.classList.remove('icon-clock');
+        icon.classList.add('icon-check');
+        text.textContent = 'In Watch List';
+      } else {
+        icon.classList.remove('icon-check');
+        icon.classList.add('icon-clock');
+        text.textContent = 'Watch Later';
+      }
+    }

+    api.handleError(error);
+  }
+});
+```
+
+### Pattern 6: Subscribe Button

+```javascript
+jQuery(".subscribe-btn").click(function() {
+  var channelId = jQuery(this).data("channel-id");
+
+  jQuery.post("/subscribe.php", { channel_id: channelId }, function(result) {
+    if (result.success) {
+      jQuery(".subscribe-btn").text("Subscribed");
+      jQuery(".subscriber-count").text(result.subscriber_count);
+    }
+  });
+});
+```
+
+**After (api-helper):**
+```javascript
+document.addEventListener('click', async (e) => {
+  const subscribeBtn = e.target.closest('.subscribe-btn');
+  if (!subscribeBtn) return;
+
+  const channelId = parseInt(subscribeBtn.dataset.channelId);
+  const isSubscribed = subscribeBtn.classList.contains('subscribed');
+
+  try {
+    if (isSubscribed) {
+      await api.unsubscribe(channelId);
+      subscribeBtn.classList.remove('subscribed');
+      subscribeBtn.textContent = 'Subscribe';
+    } else {
+      const result = await api.subscribe(channelId);
+      subscribeBtn.classList.add('subscribed');
+      subscribeBtn.textContent = 'Subscribed';
+
+      // Update subscriber count if available
+      if (result.data.subscriber_count) {
+        document.querySelector('.subscriber-count').textContent =
+          result.data.subscriber_count;
+      }
+    }
+  } catch (error) {
+    api.handleError(error);
+  }
+});
+```
+
+---
+
+## Error Handling
+
+### Comprehensive Error Handling
+
+```javascript
+async function performAction() {
+  try {
+    // Show loading state
+    showLoading();
+
+    const result = await api.someAction();
+
+    if (result.success) {
+      showSuccess('Action completed!');
+      updateUI(result.data);
+    } else {
+      showError(result.error || 'Action failed');
+    }
+
+  } catch (error) {
+    // Handle different error types
+    if (error.message.includes('Authentication')) {
+      // Redirect to login
+      window.location.href = '/signin';
+    } else if (error.message.includes('Network')) {
+      showError('Network error. Please check your connection.');
+    } else {
+      showError(error.message || 'An unexpected error occurred');
+    }
+
+    // Log error for debugging
+    console.error('Action failed:', error);
+
+  } finally {
+    // Always hide loading state
+    hideLoading();
+  }
+}
+```
+
+### Using Built-in Error Handler
+
+```javascript
+try {
+  const result = await api.someAction();
+  // Handle success
+} catch (error) {
+  // Use built-in error handler with custom callback
+  api.handleError(error, (message) => {
+    showNotification('error', message);
+  });
+}
+```
+
+### Retry Logic
+
+```javascript
+async function apiCallWithRetry(apiMethod, maxRetries = 3) {
+  let lastError;
+
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      return await apiMethod();
+    } catch (error) {
+      lastError = error;
+
+      // Don't retry on auth errors
+      if (error.message.includes('Authentication')) {
+        throw error;
+      }
+
+      // Wait before retry (exponential backoff)
+      if (i < maxRetries - 1) {
+        await new Promise(resolve => setTimeout(resolve, Math.pow(2, i) * 1000));
+      }
+    }
+  }
+
+  throw lastError;
+}
+
+// Usage
+try {
+  const result = await apiCallWithRetry(() => api.getVideos({ page: 1 }));
+} catch (error) {
+  api.handleError(error);
+}
+```
+
+---

+  let testVideoId;
+
+  beforeAll(async () => {
+    api = new EasyStreamAPI('/api');
+    await api.login('testuser', 'testpass');
+  });
+
+  test('should list videos', async () => {
+    const result = await api.getVideos({ page: 1 });
+    expect(result.success).toBe(true);
+    expect(result.data.videos).toBeInstanceOf(Array);
+  });
+
+  test('should create video', async () => {
+    const result = await api.createVideo({
+      title: 'Test Video',
+      description: 'Test description'
+    });
+    expect(result.success).toBe(true);
+    testVideoId = result.data.file_key;
+  });
+
+  test('should get single video', async () => {
+    const result = await api.getVideo(testVideoId);
+    expect(result.success).toBe(true);
+    expect(result.data.file_key).toBe(testVideoId);
+  });
+
+  afterAll(async () => {
+    if (testVideoId) {
+      await api.deleteVideo(testVideoId);
+    }
+    await api.logout();
+  });
+});
+```
+
+### Browser Console Testing
+
+Quick tests in browser console:
+
+```javascript
+// Test login
+await api.login('username', 'password')
+
+// Test get videos
+await api.getVideos({ page: 1 })
+
+// Test create comment
+await api.createComment('123456', 'Test comment')
+
+// Check authentication
+api.isAuthenticated()
+
+// View stored token
+localStorage.getItem('jwt_token')
+```
+
+---
+
+## Best Practices
+
+1. **Always use try-catch** for async API calls
+2. **Show loading states** during API requests
+3. **Provide user feedback** for success/error
+4. **Cache results** when appropriate
+5. **Debounce** search/autocomplete requests
+6. **Validate input** before sending to API
+7. **Handle edge cases** (empty results, network errors, etc.)
+8. **Log errors** for debugging
+9. **Use TypeScript** for better type safety (optional)
+10. **Test thoroughly** before deploying
+

+
+Added comprehensive methods for all endpoints:
+
+```javascript
+// Authentication
+api.login(username, password)
+api.logout()
+api.isAuthenticated()
+api.verifyToken()
+
+// Videos
+api.getVideos({ page, limit, sort, category })
+api.getVideo(videoId)
+api.searchVideos(query)
+api.createVideo(videoData)
+api.updateVideo(videoId, updates)
+api.deleteVideo(videoId)
+api.likeVideo(fileKey, 'like')

+## What Still Needs to Be Done
+
+### Phase 1: Frontend Migration (Next Priority)
+
+Migrate legacy jQuery AJAX calls to modern fetch API:
+
+**Files to Update:**
+1. `f_scripts/fe/js/browse.init.js` - Video browsing
+2. `f_scripts/fe/js/login.init.js` - Authentication forms
+3. `f_scripts/fe/js/jquery.init.js` - Global utilities
+4. Other frontend files as identified
+
+**Estimated Time:** 2-4 weeks
+
+**Impact:** Reduced page weight by ~80KB, faster load times
+
+### Phase 2: Authentication Cleanup
+
+Remove duplicate authentication systems:
+
+1. Find all `VLogin` references
+2. Replace with `VAuth`
+3. Remove `class.login.php`
+4. Test all authentication flows
+
+**Estimated Time:** 1 week
+
+**Impact:** Simpler codebase, consistent auth, better security
+
+### Phase 3: Database Optimization
+
+1. Add indexes (see LEGACY_CODE_CLEANUP_PLAN.md)
+2. Fix N+1 query issues
+3. Implement query caching
+4. Use prepared statement caching
+
+**Estimated Time:** 1-2 weeks
+
+**Impact:** 60-80% reduction in database queries
+
+### Phase 4: Performance Optimization
+
+1. Implement lazy loading
+2. Add Redis caching
+3. Minify and bundle assets
+4. Code splitting
+
+**Estimated Time:** 2-3 weeks
+
+**Impact:** 50-70% faster page loads
+
+---

+
+## Migration Guide Quick Reference
+
+### Example: Migrating Browse Videos
+
+**Before (jQuery AJAX):**
+```javascript
+jQuery.get(url, function(result) {
+    jQuery("#main-view-mode-list ul").append(result);
+});
+```
+
+**After (api-helper):**
+```javascript
+try {
+    const result = await api.getVideos({ page: 1, sort: 'popular' });
+    if (result.success) {
+        appendVideos(result.data.videos);
+    }
+} catch (error) {
+    api.handleError(error);
+}
+```
+
+### Example: Migrating Subscribe Button
+
+**Before (jQuery):**
+```javascript
+jQuery(".subscribe-btn").click(function() {
+    var channelId = jQuery(this).data("channel-id");
+    jQuery.post("/subscribe.php", { channel_id: channelId }, function(result) {
+        jQuery(".subscribe-btn").text("Subscribed");
+    });
+});
+```
+
+**After (api-helper):**
+```javascript
+document.addEventListener('click', async (e) => {
+    const btn = e.target.closest('.subscribe-btn');
+    if (!btn) return;
+
+    const channelId = parseInt(btn.dataset.channelId);
+
+    try {
+        if (btn.classList.contains('subscribed')) {
+            await api.unsubscribe(channelId);
+            btn.classList.remove('subscribed');
+            btn.textContent = 'Subscribe';
+        } else {
+            await api.subscribe(channelId);
+            btn.classList.add('subscribed');
+            btn.textContent = 'Subscribed';
+        }
+    } catch (error) {
+        api.handleError(error);
+    }
+});
+```

+
+---
+
+## Critical Removals
+
+### 1. Duplicate Authentication Systems
+
+**Problem:** Multiple authentication systems exist, causing confusion and security risks.
+
+**Files to Remove/Consolidate:**
+
+```
+REMOVE:
+- f_core/f_classes/class.login.php (Old VLogin class)
+- f_core/f_classes/class.session.php (Redundant with VAuth)
+- Any references to VLogin in other files
+
+KEEP:
+- f_core/f_classes/class.auth.php (VAuth - Modern system)
+```
+
+**Action Plan:**
+1. Search codebase for `VLogin` references
+2. Replace with `VAuth::getInstance()`
+3. Update all login forms to use VAuth
+4. Remove class.login.php entirely
+
+**Command to find VLogin usage:**
+```bash
+grep -r "VLogin" f_core/ f_modules/ *.php
+```
+
+### 2. Legacy Database Classes
+
+**Problem:** Multiple database wrapper classes causing overhead.
+
+**Files to Audit:**
+```
+f_core/f_classes/class.database.php - Keep (ADOdb wrapper)
+f_core/f_classes/db*.php - Review for redundancy
+```
+
+**Action:** Ensure all code uses `VDatabase::getInstance()` and remove any custom DB wrappers.
+
+### 3. Obsolete jQuery Plugins
+
+**Problem:** Old jQuery plugins add bloat and security vulnerabilities.
+
+**Files to Remove:**
+```
+f_scripts/be/js/init1.min.js - Contains jquery.form plugin (outdated)
+f_scripts/*/jquery.*.min.js - Review each for necessity
+```
+
+**Replace With:**
+- Native FormData API
+- Fetch API
+- Modern ES6+ code
+
+### 4. Inline JavaScript in PHP Files
+
+**Problem:** JavaScript mixed with PHP makes maintenance difficult.
+
+**Action:**
+1. Extract all `<script>` tags from PHP files
+2. Move to dedicated .js files
+3. Use data attributes for configuration
+4. Use modern module pattern
+
+**Example Files to Clean:**
+```
+browse.php - Contains inline JS
+profile.php - Contains inline JS
+upload.php - Contains inline JS
+```
+
+---
+
+## Authentication System Cleanup
+
+### Current State: 3 Auth Methods
+
+1. **Old VLogin** (deprecated)
+2. **VSession** (redundant)
+3. **VAuth** (modern, keep this)
+
+### Cleanup Steps
+
+#### Step 1: Find All VLogin Usage
+
+```bash
+# Find files using VLogin
+grep -r "VLogin" --include="*.php" .
+
+# Find session_start calls (should be in VAuth only)
+grep -r "session_start()" --include="*.php" .
+```
+
+#### Step 2: Update All References
+
+**Before:**
+```php
+$login = new VLogin();
+$login->doLogin($username, $password);
+if ($login->isLoggedIn()) {
+    // ...
+}
+```
+
+**After:**
+```php
+$auth = VAuth::getInstance();
+$result = $auth->login($identifier, $password);
+if ($auth->isAuthenticated()) {
+    // ...
+}
+```
+
+#### Step 3: Remove Old Files
+
+```bash
+# After migrating all code:
+rm f_core/f_classes/class.login.php
+rm f_core/f_classes/class.session.php
+```
+
+### Session Management Consolidation
+
+**Keep Only:**
+- VAuth for all authentication
+- VSession for session utilities (if lightweight)
+
+**Or:** Merge VSession functionality into VAuth
+
+---
+
+## Database Query Optimization
+
+### Problem: N+1 Query Issues
+
+**Current Issue:**
+```php
+// BAD: N+1 queries
+$videos = $db->execute("SELECT * FROM db_videofiles");
+while (!$videos->EOF) {
+    $user = $db->execute("SELECT * FROM db_users WHERE usr_id = ?", [$videos->fields['usr_id']]);
+    // This runs once per video!
+}
+```
+
+**Solution:**
+```php
+// GOOD: Single query with JOIN
+$sql = "SELECT v.*, u.usr_id, u.usr_user, u.usr_dname, u.usr_avatar
+        FROM db_videofiles v
+        LEFT JOIN db_users u ON v.usr_id = u.usr_id
+        WHERE v.approved = 1";
+$videos = $db->execute($sql);
+```
+
+### Remove Unnecessary Database Calls
+
+#### 1. Count Queries in Loops
+
+**Bad:**
+```php
+foreach ($videos as $video) {
+    $commentCount = $db->singleFieldValue("SELECT COUNT(*) FROM db_comments WHERE file_key = ?", [$video['file_key']]);
+}
+```
+
+**Good:**
+```php
+// Get all counts in one query
+$sql = "SELECT file_key, COUNT(*) as comment_count
+        FROM db_comments
+        WHERE file_key IN (?)
+        GROUP BY file_key";
+```
+
+#### 2. Redundant Existence Checks
+
+**Bad:**
+```php
+// Check if exists
+$exists = $db->execute("SELECT COUNT(*) FROM db_users WHERE usr_id = ?", [$userId]);
+if ($exists->fields[0] > 0) {
+    // Then fetch the user
+    $user = $db->execute("SELECT * FROM db_users WHERE usr_id = ?", [$userId]);
+}
+```
+
+**Good:**
+```php
+// Just fetch directly, check if result is empty
+$user = $db->execute("SELECT * FROM db_users WHERE usr_id = ?", [$userId]);
+if ($user && $user->RecordCount() > 0) {
+    // Use user data
+}
+```
+
+### Add Database Indexes
+
+Critical indexes to add:
+
+```sql
+-- Video queries
+CREATE INDEX idx_videofiles_approved_privacy ON db_videofiles(approved, privacy);

+## Frontend JavaScript Modernization
+
+### Remove jQuery Dependency
+
+jQuery is heavy (87KB minified) and no longer necessary.
+
+#### Migration Strategy
+
+**Phase 1: Utility Functions**
+
+Create `f_scripts/fe/js/utils.js`:
+
+```javascript
+// Modern replacements for jQuery
+const $ = {
+  // $(selector) -> document.querySelectorAll
+  select: (selector) => document.querySelectorAll(selector),
+  selectOne: (selector) => document.querySelector(selector),
+
+  // $.ajax -> fetch
+  ajax: async (url, options = {}) => {
+    const response = await fetch(url, options);
+    return response.json();
+  },
+
+  // $.get -> fetch
+  get: async (url) => {
+    const response = await fetch(url);
+    return response.json();
+  },
+
+  // $.post -> fetch
+  post: async (url, data) => {
+    const response = await fetch(url, {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify(data)
+    });
+    return response.json();
+  },
+
+  // $(element).addClass/removeClass
+  addClass: (el, className) => el.classList.add(className),
+  removeClass: (el, className) => el.classList.remove(className),
+  toggleClass: (el, className) => el.classList.toggle(className),
+
+  // $(element).show/hide
+  show: (el) => el.style.display = '',
+  hide: (el) => el.style.display = 'none',
+
+  // $(element).on
+  on: (el, event, handler) => el.addEventListener(event, handler),
+  off: (el, event, handler) => el.removeEventListener(event, handler),
+
+  // $.each -> Array.forEach
+  each: (arr, callback) => Array.from(arr).forEach(callback)
+};
+```
+
+**Phase 2: Replace jQuery Usage**
+
+**Before:**
+```javascript
+jQuery(document).ready(function() {
+  jQuery('.button').click(function() {
+    jQuery(this).addClass('active');
+  });
+});
+```
+
+**After:**
+```javascript
+document.addEventListener('DOMContentLoaded', () => {
+  document.querySelectorAll('.button').forEach(btn => {
+    btn.addEventListener('click', () => {
+      btn.classList.add('active');
+    });
+  });
+});
+```
+
+Or using event delegation (more efficient):
+```javascript
+document.addEventListener('click', (e) => {
+  if (e.target.classList.contains('button')) {
+    e.target.classList.add('active');
+  }
+});
+```
+
+### Files to Modernize
+
+Priority order:
+
+1. **High Priority (User-facing)**
+   - `browse.init.js` - Video browsing
+   - `login.init.js` - Authentication
+   - `jquery.init.js` - Global utilities
+
+2. **Medium Priority**
+   - `files.init.js` - File management
+   - `channels.init.js` - Channel features
+   - `subdashboard.js` - Dashboard
+
+3. **Low Priority**
+   - Backend admin files
+   - Analytics dashboards
+
+### Remove Unused Libraries
+
+Audit and remove:
+
+```
+f_scripts/lib/
+├── jquery.old.js - Remove if exists
+├── bootstrap.v2.js - If using v4+, remove v2
+├── moment.js - Use native Date if possible
+├── lodash.js - Use native ES6 methods
+└── underscore.js - Redundant with lodash
+```
+
+---
+
+## File Structure Reorganization
+
+### Current Issues
+
+1. **Flat file structure** - Hard to navigate
+2. **Mixed concerns** - Frontend/backend not separated
+3. **Redundant files** - Multiple versions of same functionality
+
+### Proposed Structure

+### Files to Remove
+
+```bash
+# Find duplicate/old files
+find . -name "*.old.php"
+find . -name "*.backup.php"
+find . -name "*_old.*"
+find . -name "*_backup.*"
+
+# Remove after verification
+rm [files]
+```
+
+---
+
+## Performance Optimizations
+
+### 1. Implement Lazy Loading
+
+**Videos/Images:**
+
+```javascript
+// Use Intersection Observer instead of scroll events
+const lazyLoadObserver = new IntersectionObserver((entries) => {
+  entries.forEach(entry => {
+    if (entry.isIntersecting) {
+      const img = entry.target;
+      img.src = img.dataset.src;
+      img.classList.remove('lazy');
+      lazyLoadObserver.unobserve(img);
+    }
+  });
+});
+
+document.querySelectorAll('img.lazy').forEach(img => {
+  lazyLoadObserver.observe(img);
+});
+```
+
+### 2. Implement Caching
+
+**Backend (PHP):**
+
+```php
+// Use Redis/Memcached for session storage (already configured)
+// Add query result caching
+
+class VCache {
+    private static $redis;
+
+    public static function get($key) {
+        if (!self::$redis) {
+            self::$redis = new Redis();
+            self::$redis->connect('127.0.0.1', 6379);
+        }
+        return self::$redis->get($key);
+    }
+
+    public static function set($key, $value, $ttl = 3600) {
+        if (!self::$redis) {
+            self::$redis = new Redis();
+            self::$redis->connect('127.0.0.1', 6379);
+        }
+        return self::$redis->setex($key, $ttl, serialize($value));
+    }
+}
+
+// Usage
+$cacheKey = "videos:popular:page:{$page}";
+$videos = VCache::get($cacheKey);
+
+if (!$videos) {
+    $videos = $db->execute($sql, $params);
+    VCache::set($cacheKey, $videos->GetArray(), 300); // 5 min cache
+}
+```
+
+**Frontend:**
+
+```javascript
+// Cache API responses in memory
+class APICache {
+  constructor(ttl = 60000) { // 1 minute default
+    this.cache = new Map();
+    this.ttl = ttl;
+  }
+
+  get(key) {
+    const item = this.cache.get(key);
+    if (!item) return null;
+
+    if (Date.now() > item.expires) {
+      this.cache.delete(key);
+      return null;
+    }
+
+    return item.data;
+  }
+
+  set(key, data) {
+    this.cache.set(key, {
+      data,
+      expires: Date.now() + this.ttl
+    });
+  }
+
+  clear() {
+    this.cache.clear();
+  }
+}
+
+// Add to api-helper.js
+const apiCache = new APICache();
+
+// In request method:
+const cacheKey = `${endpoint}:${JSON.stringify(params)}`;
+const cached = apiCache.get(cacheKey);
+if (cached && config.cache) {
+  return cached;
+}
+
+// After successful request:
+if (config.cache) {
+  apiCache.set(cacheKey, data);
+}
+```
+
+### 3. Optimize Database Queries
+
+**Use Prepared Statement Caching:**
+
+```php
+// In VDatabase class
+private $stmtCache = [];
+
+public function execute($sql, $params = []) {
+    $cacheKey = md5($sql);
+
+    if (!isset($this->stmtCache[$cacheKey])) {
+        $this->stmtCache[$cacheKey] = $this->connection->Prepare($sql);
+    }
+
+    return $this->connection->Execute($this->stmtCache[$cacheKey], $params);
+}
+```
+
+### 4. Minify and Bundle Assets
+
+**Create build process:**
+
+```json
+// package.json
+{
+  "scripts": {
+    "build:js": "esbuild f_scripts/fe/js/**/*.js --bundle --minify --outdir=f_scripts/fe/dist/js",
+    "build:css": "postcss f_scripts/fe/css/**/*.css --dir f_scripts/fe/dist/css --use cssnano",
+    "build": "npm run build:js && npm run build:css",
+    "watch": "npm run build -- --watch"
+  }
+}
+```
+
+### 5. Implement Code Splitting
+
+Split JavaScript into chunks:
+
+```javascript
+// Load features on demand
+async function loadVideoPlayer() {
+  const { VideoPlayer } = await import('./video-player.js');
+  return new VideoPlayer();
+}
+
+// Only load when needed
+document.querySelector('.video-container').addEventListener('click', async () => {
+  const player = await loadVideoPlayer();
+  player.play();
+}, { once: true });
+```
+
+### 6. Remove Render-Blocking Resources
+
+**Move scripts to end of body:**
+
+```html
+<!-- Before: -->
+<head>
+  <script src="jquery.js"></script>
+  <script src="app.js"></script>
+</head>
+
+<!-- After: -->
+<body>
+  <!-- content -->
+  <script src="app.js" defer></script>
+</body>
+```
+
+Or use `async` for independent scripts:
+
+```html
+<script src="analytics.js" async></script>
+```
+

+```bash
+# Page load time
+curl -o /dev/null -s -w 'Total: %{time_total}s\n' http://localhost/
+
+# Time to first byte
+curl -o /dev/null -s -w 'TTFB: %{time_starttransfer}s\n' http://localhost/
+
+# Database query count (add logging)
+grep "SELECT" /var/log/mysql/query.log | wc -l
+```
+
+### After Cleanup - Target Metrics
+
+- Page load time: < 2 seconds
+- Time to first byte: < 500ms
+- Total JavaScript size: < 200KB
+- Database queries per page: < 10
+- Memory usage: < 128MB per request
+
+---
+
+## Resource Savings Estimate
+
+### Expected Improvements
+
+| Metric | Before | After | Improvement |
+|--------|--------|-------|-------------|
+| Page Load Time | 4-6s | 1-2s | 70% faster |
+| JavaScript Size | 500KB | 150KB | 70% smaller |
+| Database Queries | 30-50 | 5-10 | 80% fewer |
+| Memory per Request | 256MB | 64MB | 75% less |
+| Server Requests | 40+ | 15-20 | 60% fewer |

+# EasyStream - Missing Features & Critical Gaps Analysis
+
+## Executive Summary
+
+EasyStream is a sophisticated video streaming platform with **1000+ PHP files** and strong Docker infrastructure. However, it has **25+ critical gaps** that need addressing before production deployment. This document prioritizes what's missing and provides implementation guidance.
+
+**Overall Maturity:** 70% (Solid foundation, needs production hardening)
+
+---
+
+## 🚨 CRITICAL PRIORITIES (Deploy Within 1-2 Weeks)
+
+### 1. Security Headers ⚠️ IMMEDIATE
+**Status:** ❌ NOT IMPLEMENTED

+
+**Missing Headers:**
+- Content-Security-Policy (CSP) - Prevents XSS attacks
+- X-Frame-Options - Prevents clickjacking
+- Strict-Transport-Security (HSTS) - Forces HTTPS
+- X-Content-Type-Options - Prevents MIME sniffing
+- Permissions-Policy - Restricts browser features
+
+**Impact:** Currently vulnerable to XSS, clickjacking, MIME-type attacks
+
+**Quick Fix:**
+```php
+// Add to config.core.php
+require_once 'f_core/config.security.php';

+    // Search

+    });
+
+    // Initial load
+    loadVideos();
+    </script>
+</body>
+</html>
+```
+
+---
+
+## 7. Error Handling
+
+Always wrap API calls in try-catch:
+
+```javascript
+try {
+    const result = await api.someAPICall();
+    // Handle success
+} catch (error) {
+    // Handle error
+    console.error('Error:', error.message);
+
+    // Use built-in error handler
+    api.handleError(error);
+
+    // Or custom handling
+    if (error.message.includes('Authentication')) {
+        window.location.href = '/signin';
+    } else {
+        alert('Error: ' + error.message);
+    }
+}
+```
+
+---
+
+## 8. Common Patterns
+
+### Loading State
+
+```javascript
+async function loadData() {
+    showLoading(); // Your loading function
+
+    try {
+        const result = await api.getVideos();
+        displayData(result.data);
+    } catch (error) {

+### Infinite Scroll
+
+```javascript
+let currentPage = 1;
+let loading = false;
+
+window.addEventListener('scroll', async () => {
+    if (loading) return;
+
+    const scrolledToBottom =
+        window.innerHeight + window.scrollY >= document.body.offsetHeight - 500;

+
+### Debounced Search
+
+```javascript
+let searchTimeout;
+
+document.getElementById('search-input').addEventListener('input', (e) => {
+    clearTimeout(searchTimeout);
+
+    searchTimeout = setTimeout(async () => {
+        const query = e.target.value;
+
+        if (query.length >= 2) {
+            const results = await api.searchVideos(query);
+            displaySearchResults(results.data.videos);
+        }
+    }, 300); // Wait 300ms after user stops typing
+});
+```

+
+## 9. Browser Console Testing
+
+Test API calls directly in the browser console:
+
+```javascript
+// Check authentication
+api.isAuthenticated()
+
+// Login
+await api.login('username', 'password')
+
+// Get videos
+await api.getVideos({ page: 1 })
+
+// Get current user
+await api.getMyProfile()
+
+// View stored token
+localStorage.getItem('jwt_token')
+
+// Clear token
+api.clearToken()
+```
+

+
+## 10. Next Steps
+
+- Read [API_DOCUMENTATION.md](API_DOCUMENTATION.md) for complete reference
+- Check [FRONTEND_BACKEND_INTEGRATION_GUIDE.md](FRONTEND_BACKEND_INTEGRATION_GUIDE.md) for advanced patterns
+- Review example code in [f_scripts/fe/js/api-helper.js](../f_scripts/fe/js/api-helper.js)
+
+---
+
+## Support
+
+If you encounter issues:
+
+1. Check browser console for errors
+2. Check Network tab to see API requests/responses
+3. Verify you're logged in: `api.isAuthenticated()`
+4. Check API documentation for correct parameters
