"ReferenceError: Markup is not defined" error in Node.Js Telegram Bot

I want to make my telegram bot automatically reply user message with Image with description.I also want to add url inline button that redirect user to specific website.

Code:

const { Telegraf, Extra } = require("telegraf");
const bot = new Telegraf('my bot token');
bot.on('text', async (ctx) => {
  const message = `Test Message`;

  const imageUrl = 'https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.bbc.com%2Fnews%2Fworld-us-canada-37493165&psig=AOvVaw0d_XITsiMbIX2n-18x9DGF&ust=1693310036962000&source=images&cd=vfe&opi=89978449&ved=0CBAQjRxqFwoTCMjv8sul_4ADFQAAAAAdAAAAABAE';
  const caption = message;
  const urlButton = Markup.inlineKeyboard([
    Markup.urlButton('Example Button', 'www.google.com'),
  ]);
});

bot.launch();
console.log('Bot Online!')

When user click the inline button, bot send error to console.

Solution

  • You need to import Markup from the telegraf library.

    const { Telegraf, Extra, Markup } = require("telegraf");
