grammY

The grammY package lets you easily write Telegram bots. Here is a quickstart for you to get started, but note that a better explanation is in our repo on GitHub.

You may also want to check out the docs.

Quickstart

Talk to @BotFather to create a new Telegram bot and obtain a bot token.

Paste the following code into a new file bot.ts.

import { Bot } from 'https://deno.land/x/grammy/mod.ts'

// Create bot object
const bot = new Bot('') // <-- place your bot token inside this string

// Listen for messages
bot.command('start', ctx => ctx.reply('Welcome! Send me a photo!'))
bot.on('message:text', ctx => ctx.reply('That is text and not a photo!'))
bot.on('message:photo', ctx => ctx.reply('Nice photo! Is that you?'))
bot.on('edited_message', ctx =>
    ctx.reply('Ha! Gotcha! You just edited this!', {
        reply_to_message_id: ctx.editedMessage.message_id,
    })
)

// Launch!
bot.start()

Congratulations! You have successfully created your first Telegram bot.

You can run it like so:

deno run --allow-env --allow-net bot.ts
