Fully switch to oxlint

[david-crespo]

Oxlint runs in 800ms without caching. Eslint runs in 14 seconds without caching, 600ms with a warm cache and no changes. So Oxlint without caching is about the same as eslint with caching.

We've been running both eslint and oxlint for a while. Now that oxlint supports type-aware rules and JS plugins, I think it's time to drop eslint. The playwright plugin runs via oxlint's experimental JS plugin support. We do lose eslint-plugin-react-hook-form for now because all 3 rules use context.getScope(), which oxlint doesn't support yet. I'll make an issue to add it back when it's supported.

Is this still the case? I believe getScope() may be implemented on the most recent releases of oxlint? https://github.com/oxc-project/oxc/blob/e9d346f1f219025229013da47386d387823c220e/apps/oxlint/src-js/plugins/scope.ts#L359

Looks like it, though only the access control rule errors like this. The other two don't seem to work, though — at least with the destructuring rule, I see things that should fail but aren't getting caught.

Warnings/errors aren't integrated into the editor extension yet for JS plugin violations, just in case you're expecting those to show up.

Otherwise, may be worth opening an issue in the oxc repo about this particular plugin having problems so they can be investigated. 🙇‍♂️

[david-crespo]

Thanks, putting it on my todo list.

While putting together a repro at https://github.com/david-crespo/oxlint-rhf-plugin-repro, Claude notes:

Note: Had to use ESLint 8.57.1 because eslint-plugin-react-hook-form also uses context.getScope() which was removed in ESLint 9 (replaced with sourceCode.getScope()). The plugin itself needs updating for ESLint 9 compatibility.

This could explain the above.

@david-crespo Looks like that is planned for support, though it won't be until late next month at the absolute earliest: oxc-project/oxc#17130

Reach out if you run into any other problems!

Thank you! Subscribed to that issue.
