  --size 120 --padding "12%" --outDir       120px with 12% of padding into the
  "./test"                                  ./test dir

Which results in a PNG which can be then used as a icon, as can be seen here.

FAQ

Why can you not find an emoji but can render it in the console!

This tool uses the NotoEmoji-Regular font which is open-source from Google. The issue is that we have to use the five-year old black & white library rather than the latest version. This is likely out of sync with the licensed fonts installed in your console.

Whats Twitter got to do with this?

If the tool cannot find an emoji witihn it's font (which is five years old now) then it uses twemoji to download a png of the emoji from a CDN.

Why not use the latest NotoColorEmoji.tff?

Be my guest friend, but note you'll first have to add CBLC/CBDT support to fontkit. You might find it tricky given the format was used by Google in Noto, but the only docs I found were by Microsoft here.

Development

Standard Node project with Typscript. It was developed inside a VSCode .devcontainer so you should be able to just use Remote-Containers to open it and all the tools will be installed. VSCode tasks and launches used for debugging.
