Hi @parlough. On a related note, I thought that you had JS (more specifically NPM-package usable) versions of the code excerpter and code-excerpt syncing tools. Did I just imagine that or are there such versions of the tools?

Hey 👋! Thanks for fixing this link!

Unfortunately we don't build JS compiled versions of the tools or publish them, as we just use them through Dart-based tooling on the site (/tool/dart_site/lib/src/commands/refresh_excerpts.dart).

Do you have a use case in mind? If the tool is useful for you, I could maybe look into polishing the packages and publishing them.
