I can start removing those "off" lint configurations in this PR or in a follow-up

Absolutely not a fan of having to change all our TypeScript files to accommodate for new lints. If Biome cannot support the existing lints we have, I don't want it.

It's just import sorting and changing the eslint comments to biome comments. I can turn off import sorting if you want. Would you accept it then? I already made sure that there are no "new" lints and it does support the existing lints. The only difference is the syntax for silencing them.

If the changes are minimal (a few edits, definitely not +677 -1,374), I still have the question whether we want it as I said on Zulip, but this is not blocking from my side.

[BenjaminBrienen]

+516 -1,174 is the lockfile being updated (no more eslint-related packages and updating typescript). The changes to *.ts files is small.

I understand, no worries if it is not wanted.

😲 I thought GitHub ignored it in the counting...

I feel it's worth taking some formatting changes if we can move to tools that are less dependent on the JS ecosystem. We''re on our third bundler, but it does feel lighter.

tools that are less dependent on the JS ecosystem.

Maybe someday VS Code will support deno.

Yea this sounds fine to me
