Is there a roadmap somewhere for the state of JS/TS affairs? I'm setting up a brand new work repo with a python backend and a frontend using TS/Angular. Since its greenfield, I'd love to be able to use pants for "everything" from the beginning. Would like to read up on how much is available for my FE needs.

I don't know if this is up to date, but there was a stabilization ticket to take it out of experimental: https://github.com/pantsbuild/pants/issues/19240

See also https://github.com/pantsbuild/pants/issues/22147. Testing is already completed i think - i think the remaining issue is a dupe. Probably the main remaining useful feature is eslint.

Thanks! Does anyone know if there are any example repos floating around out there? (with typescript, ideally)

No - but the docs in prerelease should hopefully help - https://www.pantsbuild.org/prerelease/docs/javascript/overview/enabling-typescript-support.

Does any of the javascript support (linting with prettier, in particular, but also the dependency inference) work on html/json/css files? or is it strictly JS/TS and all the other auxiliary stuff has to just be

file

targets with manual dependency mapping?

I don't know the answer to that one - suspect not.

Its been discussed to have some tools that are "targetless", but I don't think it really happened. It would be the case for these "omni-tools"
