Render math expression with typst markup language in Telegram

Try @TypstBot in Telegram or deploy as follows. First, run simple HTTP API to typst. It uses typst for rendering *.typ to *.png.

typst-telegram serve api \
    --root-dir data \
    --endpoint http://localhost:8080 \
    --interface 127.0.0.1

Finally, one can run Telegram bot itself as follows with environemnt variable TELEGRAM_BOT_TOKEN set.

typst-telegram serve bot --endpoint http://localhost:8080

mkdir data
chown -R nobody:nobody data

Finally, one can run services as follows.

docker compose up -d
