**FcaZero** là thư viện Facebook Messenger API hiện đại và mạnh mẽ nhất, được viết lại hoàn toàn bằng **TypeScript** theo kiến trúc **OOP** (Object-Oriented Programming). Dự án này là phiên bản nâng cấp từ `ws3-fca`, cung cấp API đầy đủ, type-safe và dễ mở rộng cho việc tương tác với Facebook Messenger.
## ✨ Tính năng nổi bật
### 🔐 Xác thực & Bảo mật
- **Đa phương thức đăng nhập**: AppState/Cookie, Email/Password
- **Tự động reconnect** với retry logic thông minh
- **Session management** an toàn với cookie handling
- **Proxy support** cho các khu vực bị hạn chế
- **Rate limiting** tự động để tránh bị block
### 💬 Tin nhắn & Tương tác Realtime
- **MQTT WebSocket** - Real-time messaging với hiệu suất cao
- **Gửi tin nhắn**: Text, file, sticker, emoji, mentions
- **Reply & forward** tin nhắn
- **Chỉnh sửa & thu hồi** tin nhắn đã gửi
- **Typing indicator** - hiển thị trạng thái đang gõ
- **Message reactions** - thả cảm xúc tin nhắn
- **Read receipts** - đánh dấu đã đọc, đã nhận, đã xem
- **Auto mark delivered/read** - tự động đánh dấu trạng thái
### 👥 Quản lý nhóm & người dùng
- **Thread management**: tạo nhóm, thêm/xóa thành viên
- **Admin controls**: thay đổi quyền admin, approval mode
- **Customization**: đổi tên, màu sắc, emoji, avatar nhóm
- **User info**: lấy thông tin chi tiết người dùng
- **Friends list**: quản lý danh sách bạn bè
- **Search functionality**: tìm kiếm thread và người dùng
- **Thread history**: lấy lịch sử tin nhắn với phân trang
### 🎯 Event Handling
- **Message events**: tin nhắn mới, reply, edit, unsend
- **Typing events**: trạng thái đang gõ
- **Presence events**: online/offline status
- **Thread events**: join/leave, rename, color change
- **Friend requests**: nhận/hủy lời mời kết bạn
- **Group polls**: tạo và quản lý polls trong nhóm
### 🛠️ Kiến trúc kỹ thuật
- **TypeScript 100%** với full type safety
- **Modular OOP architecture** dễ mở rộng

## 🚀 Hướng dẫn sử dụng
### 1. Chuẩn bị Credentials
#### Phương pháp 1: AppState (Khuyến nghị)
**Sử dụng Extension trình duyệt:**
1. Cài đặt extension **C3C FbState** hoặc **CookieEditor**
2. Đăng nhập Facebook
3. Xuất cookie và lưu thành file `appstate.json`:
```json
[
{
"key": "c_user",
"value": "100012345678900"
},
{
"key": "datr",
"value": "your-datr-value"
},
{
"key": "sb",
"value": "your-sb-value"
},
{
"key": "fr",
"value": "your-fr-value"
}
]
```
#### Phương pháp 2: Email/Password
```typescript
const credentials = {
email: 'your-email@gmail.com',
password: 'your-password'
};
```
### 2. Khởi tạo Client cơ bản
```typescript
import { FacebookClient } from '@jikey/fcazero';
const credentials = { appState: require('./appstate.json') };
const options = {
selfListen: false,
listenEvents: true,
autoReconnect: true,
online: true,
autoMarkRead: true,
autoMarkDelivery: false,
userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36'
};
const client = new FacebookClient(credentials, options, (err, api) => {
if (err) {
console.error('❌ Đăng nhập thất bại:', err);
return;
}
console.log('✅ Đăng nhập thành công!');
// Khởi tạo listener
startListening(api);
});
// Bắt đầu đăng nhập
client.login();
```
### 3. Lắng nghe tin nhắn với listenMqtt.call
**Cách sử dụng chính xác `api.listenMqtt.call()`:**
```typescript
function startListening(api) {
// Sử dụng .call() method đúng cách
api.listenMqtt.call(null, (err, event) => {
if (err) {
console.error('❌ MQTT Error:', err);
return;
}
console.log('📨 Event received:', event);
// Xử lý các loại event khác nhau
handleEvent(api, event);
});
}
function handleEvent(api, event) {
switch(event.type) {
case 'message':
handleMessage(api, event);
break;
case 'message_reply':
handleMessageReply(api, event);
break;
case 'message_reaction':
handleReaction(api, event);
break;
case 'message_unsend':
handleUnsend(api, event);
break;
case 'event':
handleThreadEvent(api, event);
break;
case 'typ':
handleTyping(api, event);
break;
case 'presence':
handlePresence(api, event);
break;
case 'friend_request_received':
handleFriendRequest(api, event);
break;
default:
console.log('Unknown event type:', event.type);
}
}
function handleMessage(api, event) {
const { threadID, messageID, body, senderID, attachments, mentions } = event;
console.log(`💬 ${senderID}: ${body} (${threadID})`);
// Auto-reply bot example
if (body && body.toLowerCase().startsWith('/help')) {
api.sendMessage.call({
body: `🤖 Available commands:
/help - Show this help
/ping - Check bot status
/info - Get thread info
/weather [city] - Get weather info`,
threadID
}, (err, info) => {
if (err) console.error('Send error:', err);
else console.log('✅ Help sent:', info.messageID);
});
}
// Handle mentions
if (mentions && Object.keys(mentions).length > 0) {
console.log('👥 Mentions:', mentions);
}
// Handle attachments
if (attachments && attachments.length > 0) {
attachments.forEach(att => {
console.log(`📎 Attachment: ${att.type} - ${att.url || att.name}`);
});
}
}
function handleMessageReply(api, event) {
const { threadID, messageReply, body, senderID } = event;
console.log(`↩️ Reply from ${senderID}: ${body}`);
console.log(`📨 Original message: ${messageReply?.body}`);
}
function handleReaction(api, event) {
const { threadID, messageID, reaction, senderID, userID } = event;
console.log(`😀 ${senderID} reacted ${reaction} to message ${messageID}`);
}
function handleUnsend(api, event) {
const { threadID, messageID, senderID } = event;
console.log(`🗑️ ${senderID} unsent message ${messageID} in ${threadID}`);
}
function handleTyping(api, event) {
const { threadID, from, isTyping } = event;
if (isTyping) {
console.log(`⌨️ ${from} is typing in ${threadID}...`);
} else {
console.log(`⌨️ ${from} stopped typing in ${threadID}`);
}
}
function handlePresence(api, event) {
const { userID, timestamp, statuses } = event;
console.log(`👤 ${userID} presence:`, statuses);
}
```
### 4. Advanced Message Sending

## 🔧 Xử lý sự cố
### Windows Encoding Issues
Trên Windows, có thể gặp vấn đề hiển thị tiếng Việt trong console:
```text
[04-09-2025 08:49:28] INFO: Đặng Hoài Thương -> (100092973548760)
```
**Giải pháp:**
```cmd
# Thiết lập UTF-8 cho session hiện tại
chcp 65001
# Hoặc thêm vào package.json
{
"scripts": {
"start": "chcp 65001 >nul && node index.js"
}
}
```
**Windows Terminal (khuyến nghị):**
```json
{
"profiles": {
"defaults": {
"codePage": 65001
}
}
}
```
### Common Errors & Solutions
#### 1. Login Failed
```text
❌ Error: Wrong password / email
```
**Solutions:**
- Kiểm tra lại credentials
- Sử dụng AppState thay vì email/password
- Đăng nhập bằng trình duyệt để verify account
- Kiểm tra 2FA settings
#### 2. MQTT Connection Issues
```text
❌ MQTT Error: Connection failed
```
**Solutions:**
```typescript
// Kiểm tra network và retry
const options = {
autoReconnect: true,
proxy: 'http://your-proxy:8080', // if behind firewall
bypassRegion: 'US', // bypass geo-restrictions
userAgent: 'Mozilla/5.0...' // update user agent
};
```
#### 3. Rate Limiting
```text
❌ Error: Rate limit exceeded
```
**Solutions:**
```typescript
// Implement delay between requests
const delay = (ms) => new Promise(resolve => setTimeout(resolve, ms));
async function sendMultipleMessages(api, messages) {
for (const msg of messages) {
await api.sendMessage.call(msg);
await delay(1000); // Wait 1 second between messages
}
}
```
#### 4. Memory Leaks
```typescript
// Proper cleanup
process.on('SIGINT', () => {
console.log('Shutting down gracefully...');
api.stopListeningAsync.call();
process.exit(0);
});
// Clear intervals and timeouts
const interval = setInterval(() => {
// Some repeated task
}, 5000);
process.on('exit', () => {
clearInterval(interval);
});
```
#### 5. Session Expired
```typescript
// Auto-refresh session
api.refreshConfigRequest.call(null, (err) => {
if (err) {
console.log('Session might be expired, re-login required');
// Implement re-login logic
}
});
```

### Creating Custom API Modules
```typescript
// src/api/customFeature.ts
import type { IApiModule, Callback } from '../types/IApiModule.js';
import type { Ctx } from '../types/global.js';
import type { TypedApi } from '../types/TypedApi.js';
import type { MakeDefaultsReturn } from '../types/utils/makeDefaults.js';
interface CustomFeatureInput {
targetID: string;
action: string;
data?: any;
}
interface CustomFeatureOutput {
success: boolean;
result: any;
}
export default class CustomFeature
implements IApiModule<CustomFeatureInput, CustomFeatureOutput> {
constructor(
private defaultFuncs: MakeDefaultsReturn,
private api: TypedApi,
private ctx: Ctx
) {}
call(
input: CustomFeatureInput,
callback?: Callback<CustomFeatureOutput>
): Promise<CustomFeatureOutput> {
return new Promise((resolve, reject) => {
try {
// Validate input
if (!input.targetID) {
throw new Error('targetID is required');
}
// Implement your custom logic
const form = {
target_id: input.targetID,
action: input.action,
data: JSON.stringify(input.data || {}),
fb_dtsg: this.ctx.fb_dtsg,
jazoest: this.ctx.jazoest
};
// Make API request
this.defaultFuncs.post('https://www.facebook.com/api/your-endpoint/', this.ctx.jar, form)
.then(response => {
const result = {
success: true,
result: response
};
if (callback) callback(null, result);
resolve(result);
})
.catch(error => {
if (callback) callback(error);
reject(error);
});
} catch (error) {
if (callback) callback(error as Error);
reject(error);
}
});
}
}
```
### Event System Extensions
```typescript
// Custom event handler
class AdvancedEventHandler {
private api: TypedApi;
private messageQueue: any[] = [];
private rateLimiter: Map<string, number> = new Map();
constructor(api: TypedApi) {
this.api = api;
this.setupEventListeners();
}
private setupEventListeners() {
this.api.listenMqtt.call(null, (err, event) => {
if (err) return;
// Rate limiting per thread
if (this.isRateLimited(event.threadID)) {
this.messageQueue.push(event);
return;
}
this.handleEvent(event);
});
// Process queued messages
setInterval(() => this.processQueue(), 1000);
}
private isRateLimited(threadID: string): boolean {
const now = Date.now();
const lastMessage = this.rateLimiter.get(threadID) || 0;
if (now - lastMessage < 1000) { // 1 second cooldown
return true;
}
this.rateLimiter.set(threadID, now);
return false;
}
private handleEvent(event: any) {
switch(event.type) {
case 'message':
this.handleMessage(event);
break;
case 'message_reaction':
this.handleReaction(event);
break;
// Add more event types
}
}
private handleMessage(event: any) {
// Advanced message processing
if (event.body?.includes('!admin')) {
this.handleAdminCommand(event);
} else if (event.attachments?.length > 0) {
this.handleAttachments(event);
}
}
private processQueue() {
if (this.messageQueue.length === 0) return;
const event = this.messageQueue.shift();
if (!this.isRateLimited(event.threadID)) {
this.handleEvent(event);
} else {
this.messageQueue.unshift(event); // Put back in queue
}
}
}
```
### Plugin System
```typescript
// Plugin interface
interface FcaPlugin {
name: string;
version: string;
init(api: TypedApi, ctx: Ctx): void;
destroy?(): void;
}
// Example plugin
class AutoResponderPlugin implements FcaPlugin {
name = 'auto-responder';
version = '1.0.0';
private api: TypedApi;
private responses: Map<string, string> = new Map();
init(api: TypedApi, ctx: Ctx) {
this.api = api;
// Load responses from config
this.responses.set('hello', 'Hi there! 👋');
this.responses.set('time', () => `Current time: ${new Date().toLocaleString()}`);
// Listen for messages
api.listenMqtt.call(null, (err, event) => {
if (err || event.type !== 'message') return;
const response = this.getResponse(event.body);
if (response) {
api.sendMessage.call({
body: typeof response === 'function' ? response() : response,
threadID: event.threadID
});
}
});
}
private getResponse(message: string): string | (() => string) | null {
const normalizedMessage = message.toLowerCase().trim();
return this.responses.get(normalizedMessage) || null;
}
destroy() {
this.responses.clear();
}
}
// Plugin manager
class PluginManager {
private plugins: FcaPlugin[] = [];
register(plugin: FcaPlugin, api: TypedApi, ctx: Ctx) {
plugin.init(api, ctx);
this.plugins.push(plugin);
console.log(`Plugin "${plugin.name}" v${plugin.version} loaded`);
}
unregisterAll() {
this.plugins.forEach(plugin => {
if (plugin.destroy) plugin.destroy();
});
this.plugins = [];
}
}
```
