⚡ Quick Start

Basic Usage

import { WhatsAppClient } from '@akson/chatsuite-sdk';

const client = new WhatsAppClient({
  apiToken: 'wa_your_token_here'
});

// Send a message
await client.messages.sendText('+1234567890', '[email protected]', 'Hello!');

🚀 Complete Automation (30 lines replaces 775+ lines!)

import { WhatsAppClient, ConsoleExporter } from '@akson/chatsuite-sdk';

const client = new WhatsAppClient({
  apiToken: 'wa_your_token_here'
});

// Complete WhatsApp automation in just a few lines
const automation = await client.createAutomation('+1234567890', {
  name: 'My WhatsApp Bot',
  webhookUrl: 'https://my-server.com/webhook',
  
  // Bot with commands and middleware
  bot: {
    prefix: '!',
    maxCommandsPerMinute: 10
  },
  
  // Message queue with rate limiting
  queue: {
    maxConcurrent: 5,
    rateLimitPerMinute: 30
  },
  
  // Database sync
  database: {
    uri: 'mongodb://localhost:27017',
    collections: {
      messages: 'whatsapp_messages',
      chats: 'whatsapp_chats'
    }
  },
  
  // Smart polling
  polling: {
    interval: 5 * 60 * 1000,
    strategy: 'smart'
  },
  
  // Metrics collection
  metrics: {
    enabled: true,
    collectors: ['messages', 'sessions'],
    exporters: [new ConsoleExporter()]
  }
});

// Bot is ready with all features!
console.log('Automation active:', automation);

🤖 Enhanced Automation Features

Bot Framework

Create sophisticated bots with command parsing and middleware:

// Create bot
const bot = client.createBot('+1234567890', {
  prefix: '!',
  maxCommandsPerMinute: 10
});

// Add middleware
bot.use(middleware.userContext(getUserFromDB));
bot.use(middleware.logging());

// Add commands
bot.addCommand({
  name: 'order',
  description: 'Check order status',
  handler: async (context, args) => {
    const orderId = args[0];
    const order = await getOrder(orderId);
    return `Order ${orderId}: ${order.status}`;
  }
});

bot.start();

Message Queue

Handle bulk messaging with rate limiting and priorities:

// Create queue
const queue = client.createMessageQueue({
  maxConcurrent: 5,
  rateLimitPerMinute: 30
});

// Add messages
await queue.enqueue({
  tel: '+1234567890',
  chatId: '[email protected]',
  content: { text: 'Urgent notification!' },
  type: 'text',
  priority: 'urgent'
});

queue.start();

Database Sync

Automatically sync WhatsApp data to MongoDB:

// Create database adapter
const dbAdapter = client.createDatabaseAdapter({
  uri: 'mongodb://localhost:27017',
  collections: { messages: 'whatsapp_messages' },
  fieldMapping: {
    'key.id': 'messageId',
    'messageTimestamp': {
      target: 'timestamp',
      transform: (ts) => new Date(ts * 1000)
    }
  }
});

await dbAdapter.connect();
await dbAdapter.sync('messages', messages);

Polling Service

Smart message syncing with adaptive intervals:

// Create polling service
const poller = client.createPollingService('+1234567890', {
  interval: 5 * 60 * 1000,
  strategy: 'smart'
});

poller.start();

Session Management

Advanced session handling with health monitoring:

// Create session manager
const sessionManager = client.createSessionManager({
  autoRestart: true,
  healthCheckInterval: 60000
});

await sessionManager.restoreSession('+1234567890');

Metrics Collection

Monitor performance and collect observability data:

// Create metrics collector
const metrics = client.createMetricsCollector({
  enabled: true,
  exporters: [new ConsoleExporter(), new PrometheusExporter()]
});

metrics.increment('messages_sent_total');
metrics.histogram('message_duration_ms', duration);

📱 Core API Features

Session Management

// List sessions
const sessions = await client.sessions.list();

// Quick session setup with QR polling
const result = await client.quickStart('+1234567890', 'My Bot');
console.log('Scan QR:', result.session.qr);

Messages

// Send text
await client.messages.sendText('+1234567890', '[email protected]', 'Hello!');

await client.messages.sendButtons('+1234567890', '[email protected]', 'Choose:', [
  { id: '1', text: 'Option 1' },
  { id: '2', text: 'Option 2' }
]);

// Send polls
await client.messages.sendPoll('+1234567890', '[email protected]', 'Question?', [
  'Option A', 'Option B'
]);

Groups & Business

const group = await client.groups.create({
  tel: '+1234567890',
  name: 'Team Chat',
  participants: ['[email protected]', '[email protected]']
});

// Business catalog
const products = await client.business.listProducts('+1234567890');
await client.business.createCart('+1234567890', '[email protected]');

Error Handling

try {
  await client.messages.sendText(tel, to, text);
} catch (error) {
  if (error instanceof ApiError) {
    console.error('API Error:', {
      message: error.message,
      status: error.status,
      code: error.code
    });
  }
}
