# Frontend-Backend Integration Guide
|
||||
|
||||
## Overview
|
||||
|
||||
This guide explains how to properly connect EasyStream's frontend JavaScript code with the backend API endpoints. It covers migrating from legacy jQuery AJAX calls to modern fetch API using the provided `api-helper.js` client.

## 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
|
||||
jQuery.post(url, {
|
||||
field1: value1,
|
||||
field2: value2
|
||||
}, function(result) {
|
||||
if (result.success) {
|
||||
showSuccess('Saved!');
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
**After (api-helper):**
|
||||
```javascript
|
||||
try {
|
||||
const result = await api.post(url, {
|
||||
field1: value1,
|
||||
field2: value2
|
||||
});
|
||||
|
||||
if (result.success) {
|
||||
showSuccess('Saved!');
|
||||
}
|
||||
} catch (error) {
|
||||
api.handleError(error);
|
||||
}
|
||||
```
|
||||
|
||||
### Pattern 3: Load More / Pagination
|
||||
|
||||
**Before (jQuery):**
|
||||
```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.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) {
|
||||
e.preventDefault();
|
||||
|
||||
var formData = jQuery(this).serialize();
|
||||
|
||||
jQuery.post("/submit-comment.php", formData, function(result) {
|
||||
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 commentText = formData.get('comment_text');
|
||||
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';
|
||||
}
|
||||
}
|
||||
} catch (error) {
|
||||
api.handleError(error);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Pattern 6: 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) {
|

|
||||
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';
|
||||
|

|
||||
## 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);
|
||||
}
|
||||
```

### Automated Testing
|
||||
|
||||
Create test files in `tests/integration/`:
|
||||
|
||||
```javascript
|
||||
// Example: test-videos-api.js
|
||||
describe('Videos API Integration', () => {
|
||||
let api;
|
||||
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
