I'm running into this problem at the moment with biome and eslint+prettier bumping into each other. I'll try and sort out the config on my end and then contribute it back here.

This is a bit annoying as the 95% of use cases is that you're either in a project that uses biome OR eslint+prettier, which is fine to configure, but it's possible that some people may want something like eslint with biome for formatting or some other configuration.

There's even the argument about HOW we run the LSP. I'd say we expect it to be in the projects dependencies and invoke it via npx/yarn/pnpm biome lsp-proxy, but they COULD use mason...

Do you guys want to cover all use cases or just go for the most common one?

I'm in two projects currently where we're using biome as the formatter and eslint as the linter while migrating a bunch of stuff.

Could we check for the existence of a biome.json config and use that to make decisions? It might be short-sighted but in my head any project where biome has "formatter": { "enabled": true } turned on I think would be the true formatter even if prettier is still in node modules somewhere, since you have to manually opt-into Biome formatting by declaring it. Same thing in reverse for "linter": { "enabled": true } (thought I can't think of many scenarios where you'd use biome as a linter and prettier as a formatter)

Go for the most common one, and install it trough mason for now.

I've started work on this here: https://github.com/AstroNvim/astrocommunity/pull/1006/files

Having everything supported is pretty finicky :/
