Warning

mtcute is currently in alpha stage: the api is not very stable yet, and there may be a lot of bugs
feel free to try it out, though, any feedback is appreciated!

releases may not follow semver just yet, so please pin the versions for now

import { TelegramClient } from '@mtcute/node'
import { Dispatcher, filters } from '@mtcute/dispatcher'

const tg = new TelegramClient({
    apiId: parseInt(process.env.API_ID),
    apiHash: process.env.API_HASH,
    storage: 'my-account'
})
const dp = Dispatcher.for(tg)

dp.onNewMessage(filters.chat('private'), async (msg) => {
    await msg.replyText('hiiii from mtcute! 🌸')
})

tg.run({ /* optional params */ }, async (self) => {
    console.log(`✨ logged in as ${self.displayName}`)
})

project goals

mtcute strives to:

• be customizable enough to fit most of the possible use-cases
• be lightweight, both in terms of runtime and bundle size
• support (theoretically) any environment without much hassle
• provide a solid foundation for all kinds of applications on telegram platform
• provide a convenient high-level api for the most commonly used features

mtcute is NOT and will never be:

• a library for spam/flood or otherwise malicious activities
• a fully feature-complete library - highlevel apis will never cover the entirety of the apis. feel free to contribute, though!
• a drop-in replacement for (insert library name)
• a teapot

setting up for development

git clone https://github.com/mtcute/mtcute
fnm use # or `nvm use`
cd mtcute
pnpm install --frozen-lockfile

# generate code from tl schema
pnpm -C packages/tl run gen-code
