Switch to Biome

[cometkim]

• Compatible with Prettier's formatting rules
• Can lint
• Can organize imports
• Much faster than Prettier, even when performing formatting, linting, and import sorting altogether.
• A better editor experience because it allows partial errors.
• Integrated with Git and check only changes without additional tools.
• Healthier maintenance

That does look nice! Is there any downside to it (other than people being unfamiliar with it)?

[cometkim]

I don't think so. It can be compared to ESLint in terms of ecosystem, but not to Prettier.

People who are already using the Prettier extension should switch to the Biome extension.

Btw, do we need to enable the linter rules & import sorting feature too?

Would certainly be nice to help us cleaning up / modernizing the JS files.

But that can also be done later - fine with me to merge only the formatting part now. (Is it ready to merge - as the PR is still in draft?)

[cometkim]

The CI now only checks for changes, so I ran npm run format:all once.

Formatted 126 files in 73ms. Fixed 18 files.
Found 4 errors.

sooo fast 👍 (errors were comments in JSON files)

[cometkim]

Ohh, the gentype test includes ESLint.

We can replace it with Biome check. Wait for it...

[cometkim]

Done!

[cknitt]

Merged your other PR #6831 in the meantime, and now this one has a conflict.

[cometkim]

rebased

make format and make checkformat should also call this I think, not just the ocaml dune format.
