Create Your Own Telegram Bot - A DIY Guide

Step 1: Create Your Bot Token with BotFather

• Open Telegram and search for @BotFather.
• Use the command /newbot to create a new bot and receive your Bot Token.
• Save the bot token for later use.

Step 2: Set Up Your Project

• Create a folder for your bot and run npm init -y in the terminal.
• Install the required dependency using npm install node-telegram-bot-api.

Step 3: Write the Bot Code

Create a file called bot.js and use the following code:

const TelegramBot = require('node-telegram-bot-api');

const token = 'YOUR_BOT_TOKEN_HERE';
const bot = new TelegramBot(token, { polling: true });

bot.on('message', (msg) => {
  const chatId = msg.chat.id;

  if (msg.text.toLowerCase() === '/start') {
    bot.sendMessage(chatId, 'Welcome! I am your new bot. Use /help to see what I can do!');
  } else if (msg.text.toLowerCase() === '/help') {
    bot.sendMessage(chatId, 'Available commands: \n/start - Start the bot\n/help - Get help');
  } 
});
            

Replace YOUR_BOT_TOKEN_HERE with the token from BotFather.

Step 4: Run the Bot

• Run the bot using node bot.js.
• Open Telegram, find your bot, and interact using commands like /start and /help.

To ensure your bot runs continuously, consider hosting it:

• VPS Hosting: Purchase a VPS from providers like DigitalOcean or AWS.
• Free Hosting: Use cloud services like Heroku for a free and easy deployment option.

Troubleshooting

• Ensure the bot is running without errors in the terminal.
• Double-check that the Bot Token is correct.

Extending Your Bot

• Add more commands to improve your bot's functionality.
• Integrate APIs like cryptocurrency price checkers using packages like axios.
