🚀 Quick Start

Polling Mode

import { Bot } from 'turbogram-v1';

const bot = new Bot({ token: 'YOUR_BOT_TOKEN' });

bot.command('/start', async (ctx) => {
  await ctx.reply('Welcome!');
});

bot.startPolling();

Webhook Mode

const bot = new Bot({ token: 'YOUR_BOT_TOKEN' });

bot.startWebhook({ port: 3000, url: 'https://domain.com/webhook' });

⚠️ Important: Correct Usage Guide

✅ DO: Always use async/await

// ✅ CORRECT - Using async/await
bot.command('/start', async (ctx) => {
  await ctx.reply('Hello World!');
});

bot.on('callback_query', async (ctx) => {
  // Always answer callback first
  await ctx.answerCallback();
  
  // Then edit or reply
  await ctx.edit('Updated text');
});

❌ DON'T: Forget async/await

// ❌ WRONG - Missing async/await
bot.command('/start', (ctx) => {
  ctx.reply('Hello World!'); // Promise not awaited!
});

bot.on('callback_query', (ctx) => {
  ctx.edit('Updated text'); // Will fail silently!
});

🎹 Complete Keyboard Examples

Inline Keyboard with Callbacks

import { InlineKeyboard } from 'turbogram-v1';

bot.command('/menu', async (ctx) => {
  const keyboard = InlineKeyboard()
    .callback('✅ Approve', 'approve')
    .callback('❌ Reject', 'reject')
    .row()
    .url('🌐 Website', 'https://example.com')
    .switchInline('📤 Share', 'check this')
    .row()
    .callback('🔙 Back', 'back')
    .build();

  await ctx.reply('Choose an action:', { reply_markup: keyboard });
});

// Handle callbacks correctly
bot.on('callback_query', async (ctx) => {
  const data = ctx.callbackQuery?.data;
  
  // IMPORTANT: Always answer callback first!
  await ctx.answerCallback();
  
  // Then handle the action
  switch (data) {
    case 'approve':
      await ctx.edit('✅ Approved!');
      break;
    case 'reject':
      await ctx.edit('❌ Rejected!');
      break;
    case 'back':
      await ctx.edit('🔙 Back to main menu');
      break;
  }
});

Reply Keyboard with Options

import { ReplyKeyboard, RemoveKeyboard } from 'turbogram-v1';

bot.command('/contact', async (ctx) => {
  const keyboard = ReplyKeyboard()
    .resize(true)
    .oneTime(true)
    .placeholder('Share your info...')
    .contactRequest('📱 Share Contact')
    .row()
    .locationRequest('📍 Share Location')
    .row()
    .text('❌ Cancel')
    .build();

  await ctx.reply('Please share your information:', {
    reply_markup: keyboard
  });
});

bot.hears('❌ Cancel', async (ctx) => {
  await ctx.reply('Keyboard removed. Use /start to return.', {
    reply_markup: RemoveKeyboard()
  });
});

🔄 Callback Query Best Practices

✅ Correct Pattern

// Always follow this pattern for callbacks
bot.on('callback_query', async (ctx) => {
  const data = ctx.callbackQuery?.data;
  const userId = ctx.from?.id;
  
  // Step 1: Answer callback immediately
  await ctx.answerCallback();
  
  // Step 2: Try to edit the message
  try {
    await ctx.edit(`You selected: ${data}`, {
      reply_markup: newKeyboard
    });
  } catch (error) {
    // Step 3: If edit fails, send new message
    console.log('Edit failed, sending new message');
    await ctx.reply(`You selected: ${data}`, {
      reply_markup: newKeyboard
    });
  }
});

❌ Wrong Pattern (Will Cause Errors)

// DON'T DO THIS!
bot.on('callback_query', (ctx) => {
  const data = ctx.callbackQuery?.data;
  
  // Missing async/await
  // Missing answerCallback first
  // Missing error handling
  ctx.edit(`You selected: ${data}`); // ❌ Will fail!
});

📝 Message Editing Guide

edit() vs editMessageText()

// ctx.edit() - Automatically uses current message ID
await ctx.edit('Updated text', {
  parse_mode: 'HTML',
  reply_markup: keyboard
});

// ctx.editMessageText() - Same but more explicit
await ctx.editMessageText('Updated text', {
  chat_id: chatId,
  message_id: messageId,
  parse_mode: 'HTML',
  reply_markup: keyboard
});

When Edit Fails

// Safe edit function
async function safeEdit(ctx, text, options = {}) {
  try {
    // Check if text is not empty
    if (!text || text.trim() === '') {
      throw new Error('Text cannot be empty');
    }
    
    // Try to edit
    await ctx.edit(text, options);
    return true;
  } catch (error) {
    // If edit fails, send new message
    console.log('Edit failed:', error.message);
    await ctx.reply(text, options);
    return false;
  }
}

// Usage
bot.on('callback_query', async (ctx) => {
  await ctx.answerCallback();
  
  await safeEdit(ctx, '✅ Action completed!', {
    reply_markup: getMainMenuKeyboard()
  });
});

💾 Session Manager

Store user data across messages:

import { SessionManager, sessionMiddleware, MemoryStorage } from 'turbogram-v1';

const sessions = new SessionManager({
  ttl: 3600, // 1 hour
  storage: new MemoryStorage(),
});

bot.use(sessionMiddleware(sessions));

// Now ctx.session is available
bot.on('text', async (ctx) => {
  ctx.session.messageCount = (ctx.session.messageCount || 0) + 1;
  ctx.session.lastMessage = ctx.message?.text;
  
  await ctx.reply(`Messages sent: ${ctx.session.messageCount}`);
});

🎭 Scene Manager

Build complex multi-step flows:

import { SceneManager } from 'turbogram-v1';

const scenes = new SceneManager();

scenes.scene('order')
  .enter('order', async (ctx) => {
    await ctx.reply('What would you like to order?');
  })
  .hear('order', /pizza|burger/i, async (ctx) => {
    ctx.session.order = ctx.message?.text;
    await ctx.reply('What size? (Small/Medium/Large)');
  })
  .hear('order', /small|medium|large/i, async (ctx) => {
    ctx.session.size = ctx.message?.text;
    await ctx.reply(`✅ Ordered: ${ctx.session.size} ${ctx.session.order}!`);
    await ctx.leave();
  });

scenes.default('main');
bot.use(scenes.middleware());

bot.command('/order', async (ctx) => {
  await ctx.enter('order');
});

💬 Conversation Manager

Natural dialog flows with validation:

import { ConversationManager } from 'turbogram-v1';

const conversations = new ConversationManager();
bot.use(conversations.middleware());

bot.command('/register', async (ctx) => {
  await conversations.startConversation(ctx, {
    id: 'registration',
    steps: [
      {
        question: 'What is your name?',
        validate: (answer) => answer.length >= 2,
        errorMessage: 'Name must be at least 2 characters.',
      },
      {
        question: 'How old are you?',
        validate: (answer) => {
          const age = parseInt(answer);
          return age >= 13 && age <= 120;
        },
        errorMessage: 'Please enter a valid age (13-120).',
        transform: (answer) => parseInt(answer),
      },
    ],
    onComplete: async (answers, ctx) => {
      await ctx.replyHTML(`
<b>✅ Registration Complete!</b>
<b>Name:</b> ${answers.step_0}
<b>Age:</b> ${answers.step_1}
      `);
    },
    onCancel: async (ctx) => {
      await ctx.reply('❌ Registration cancelled.');
    },
    timeout: 300000,
  });
});

📡 Broadcast System

await bot.broadcast({
  chatIds: [123, 456, 789],
  text: '📢 Important Announcement',
  options: {
    concurrency: 5,
    delay: 50,
    retry: 3,
    ignoreErrors: true,
    onProgress: (sent, total) => {
      console.log(`Progress: ${sent}/${total}`);
    },
    onComplete: (results) => {
      console.log(`✅ Sent ${results.length} messages`);
    },
    onError: (error, chatId) => {
      console.error(`Failed for ${chatId}:`, error.message);
    }
  }
});
