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 grammyinside 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)
bot.start();Now you can run the bot via
node bot.jsand it will echo all received text messages.
Congrats! You just wrote a Telegram bot :)
grammY has an excellent documentation, and an API Reference. It even integrates with your code editor, e.g. VS Code. You can hover over any element of grammY to get a detailed description of what that thing does or means.

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.
The grammY core package in this repository is available as a JavaScript bundle via https://bundle.deno.dev/.
This lets you transpile all published versions including current main branch to standalone JavaScript files.
For example, the most recent source on main is available from https://bundle.deno.dev/https://raw.githubusercontent.com/grammyjs/grammY/main/src/mod.ts.
Being compatible with browsers is especially useful for running bots on Cloudflare Workers.
For this reason, we also include a web bundle in our npm package.
You can simply do import { Bot } from "grammy/web".
