Nodeenv demo

[ilyagr]

UPDATE: I'll likely close this soon. I remembered that https://pre-commit.com/ is likely a better option than nodeenv. IIRC, it can install Node+Pretter in a hermetic way, removing the need for a package.json. It should be possible to install pre-commit with Poetry or pipx.

OTOH, I'm not sure pre-commit currently has a working Prettier plugin. pre-commit/pre-commit#3133

---

This is a demo of using nodeenv to install Prettier for #3757. It may or may not be later fleshed out to a real PR.

Try

poetry install
poetry run -- nodeenv -p
poetry run -- npm install  # After merging this PR with #3757.

If we wanted to use this approach for real, we'd probably want to either use something like https://python-poetry.org/docs/pyproject#scripts or a cargo xtask.

Some kind of solution for defining tasks like cargo xtask would be good to add even without the formatting PR (because I generally wouldn't want to figure out the exact invocation to build+serve docs for testing 😅). I think pre-commit as a general "checks" framework is good, but it doesn't seem like it supports general tasks (like a long-running mkdocs server). I would definitely prefer to keep as much as possible in the Rust ecosystem, so cargo xtask seems like a natural choice.

I like the idea of cargo xtask too, but it doesn't solve every problem (e.g. setting up the environment), and I never quite get past setting up the boilerplate I'd need to find out how much more verbose it has to be as compared to a shell script.

I'll close this. I think DPrint is a better option; it can be cargo-installed.
