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
