Maybe we soon don't need prettier anymore: https://biomejs.dev/

It doesn't have yaml support yet though

[Zethson]

I'm actually hoping that the Astral reimplements the rules in Ruff.

I have just started removing prettier from my setups, I'd probably be more up for that here

[flying-sheep]

@Zethson Ruff does Python and things that contain Python (docstrings, Jupyter notebooks). We use prettier for JSON, YAML, and in some cases Markdown.

@ivirshup what are you replacing it with? Biome or something else?

Can't harm to have node_modules in .gitignore.

Merging this. Opening separate issue to discuss prettier alternatives.
