Telegram Bot con Nodejs y Javascript

En este ejemplo práctico aprenderemos a crear un bot de Telegram con Nodejs y Javascript usando un modulo de npm llamado Telegraf, el cual nos permite programar nuestro bot sin tener que interactuar directamente con la API de telegram.

GrammY: The Telegram Bot Framework


The Telegram Bot Framework.

grammY makes it easy to create Telegram bots. Both for beginners and at scale.

You want grammY because it is easy to use. It is very powerful and always up to date. It has the best documentation in town. It is extremely efficient and scales up effortlessly. It has a thriving ecosystem of plugins, a friendly community chat, seamless integrations with web frameworks and databases, and so much more.

Are you ready? 🤖🚀

Bots are written in TypeScript (or JavaScript) and run on Node.js or Deno.


If you are new to Telegram bots, read the official Introduction for Developers written by the Telegram team.

Visit @BotFather and create a new bot. You will obtain a bot token.

Create a new directory and run

npm install grammy

inside it. Then create a file bot.js with this content:

const { Bot } = require("grammy");

// Create a bot object
const bot = new Bot(""); // <-- place your bot token in this string

// Register listeners to handle messages
bot.on("message:text", (ctx) => ctx.reply("Echo: " + ctx.message.text));

// Start the bot (using long polling)

Now you can run the bot via

node bot.js

and it will echo all received text messages.

Congrats! You just wrote a Telegram bot :)

Going Further

grammY has an excellent documentation, and an API Reference. It even integrates with your code editor, e.g. VSCode. You can hover over any element of grammY to get a detailed description of what that thing does or means.

If you are still stuck, just join the Telegram chat and ask for help. People are nice there and we appreciate your question, no matter what it is :)

Here are some more resources to support you:


grammY Website

—main project website and documentation. Gets you started and explains all concepts.

grammY API Reference

—reference of everything that grammY exports. Useful to look up descriptions about any element of grammY.

grammY Example Bots

—repository full of example bots. Includes a setup to easily run any of them.

Awesome grammY

—list of awesome projects built with grammY. Helpful if you want to see some real-world usage.

grammY Telegram Chat

—Telegram chat where you can ask any question about grammY or bots in general. We are also open for feedback, ideas, and contributions!

The Russian community chat can be found here.

grammY News Channel

—Telegram channel where updates to grammY and the ecosystem are posted. We are also on Twitter.

Telegram Bot API Reference

—documentation of the API that Telegram offers, and that grammY connects to under the hood.

Deno Support

All grammY packages published by @grammyjs run natively on Deno. We are compiling every codebase to still run on Node.js.

However, given that most bot developers are still using Node.js, all documentation is written Node.js-first. We may migrate it if Deno overtakes Node.js. If you are already on Deno today, import grammY from https://deno.land/x/grammy/mod.ts.

You may also be interested in why we support Deno.

Browser Support

The grammY core package in this repository is available as a JavaScript bundle from the CDN at get.grammy.dev. Currently, we transpile all stable versions (all releases since v1.0) as well as the current main branch to ES6 and ESNext.

You can download them from the URL https://get.grammy.dev/[ES version lowercased]@[grammY version including v-prefix].js. For example, the most recent source on main in ES6 is available from https://get.grammy.dev/es6@dev.js.

Being compatible with browsers is especially useful for running bots on Cloudflare Workers. For this reason, we include the web bundle in our npm package. You can simply do import { Bot } from "grammy/web".

Decoding Nodejs

The main goal of this blog is to explain the “Architecture of Nodejs” and to know how the Nodejs works behind the scenes,

Generally, most of the server-side languages, like PHP, ASP.NET, Ruby, and including Nodejs follows multi-threaded architecture. That means for each client-side request initiates a new thread or even a new process.

In Nodejs, all those requests from the clients are handled in a single-thread using shared resources concurrently as It follows the “Single-Threaded Event Loop Model”.



Event-Loop programming is a flow control in an application-defined by events. The basic principle of Nodejs’s event-driven loop is implementing a central mechanism that hears for events and calls the callback function once an event is turning up.

Nodejs is an event-loop that implements a run-time environment model to achieve non-blocking asynchronous behavior runs on Google Chrome’s V8 engine.

Telegram Bot API for NodeJS

Node.js Telegram Bot API

Node.js module to interact with the official Telegram Bot API.


npm i node-telegram-bot-api


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

// replace the value below with the Telegram token you receive from @BotFather
const token = 'YOUR_TELEGRAM_BOT_TOKEN';

// Create a bot that uses 'polling' to fetch new updates
const bot = new TelegramBot(token, {polling: true});

// Matches "/echo [whatever]"
bot.onText(/\/echo (.+)/, (msg, match) => {
  // 'msg' is the received Message from Telegram
  // 'match' is the result of executing the regexp above on the text content
  // of the message

  const chatId = msg.chat.id;
  const resp = match[1]; // the captured "whatever"

  // send back the matched "whatever" to the chat
  bot.sendMessage(chatId, resp);

// Listen for any kind of message. There are different kinds of
// messages.
bot.on('message', (msg) => {
  const chatId = msg.chat.id;

  // send a message to the chat acknowledging receipt of their message
  bot.sendMessage(chatId, 'Received your message');


Note: Development is done against the master branch. Code for the latest release resides on the release branch. Experimental features reside on the experimental branch.

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */
