Oxlint JS Plugins compatibility

[overlookmotel]

Please share info here about ESLint plugins tested and found to be working.

If you find that a plugin doesn't work, please open a separate issue - Oxlint aims to support all existing ESLint plugins, and it's a bug if any don't work.

Only exceptions to that rule at present are:

• Custom file formats and parsers (e.g. Svelte, Vue, Angular) are not supported.
• Lint rules that rely on TypeScript type-awareness are not supported.

Each comment should include only one plugin name to make it searchable. Also make sure to include Oxlint version that was tested.

PRs to add more plugins to our conformance testing are very welcome!

ESLint built-in rules

100% tests passing for 292 rules. Conformance tests snapshot

[overlookmotel]

eslint-plugin-react-hooks

100% tests passing. Conformance tests snapshot

14 tests skipped: Flow syntax (unsupported) + misconfigured tests.

ESLint Stylistic (@stylistic/eslint-plugin)

99.99% tests passing for 129 rules. Conformance tests snapshot

1 test failing out of 18310: Obscure edge case where rule relies on cloning AST node object with Object.assign and then accessing loc property. Does not work because loc property of AST nodes in Oxlint is a getter on the prototype, so it doesn't get cloned. We hope to fix in the plugin.

106 tests skipped:

• Invalid source e.g. let foo,.
• Flow syntax (unsupported).
• Faulty test cases (these tests would fail with ESLint's RuleTester too).
• Tests test 2 rules simultaneously (unsupported by RuleTester).

eslint-plugin-testing-library

100% tests passing for 29 rules. Conformance tests snapshot

1 test skipped out of 17017: Test case uses invalid option.

[overlookmotel]

eslint-plugin-sonarjs

99.6% tests passing for 360 rules. Conformance tests snapshot

14 tests failing out of 3951: All failures are on no-commented-code due to Oxlint not supporting context.languageOptions.parser at present (tracked in #19918).

531 tests skipped: Rules require TS type info (unsupported).

[overlookmotel]

@e18e/eslint-plugin

100% tests passing for 18 rules. Conformance tests snapshot

38 tests skipped out of 512: Rules require TS type info (unsupported).

eslint-plugin-storybook

Oxlint v1.56.0

100% tests passing for 16 rules. Pull Request adding it to the conformance suite

161 tests are passing out of 161.

[overlookmotel]

I fixed the tests for that last rule - it was a problem with the test cases, not a problem with Oxlint.

100% tests now passing for all rules (161 tests total).

eslint-plugin-playwright

Oxlint v1.56.0

99.9% tests passing for 58 rules, 1 rule has failing tests. Pull Request adding it to the conformance suite

4 tests are failing out of 3048: haven't investigated the specific reasons for the failures yet.

[overlookmotel]

The 4 failing tests are where there are RegExps used as options to the valid-test-tags rule. Oxlint doesn't currently support this: #20530.

eslint-plugin-cypress

Oxlint v1.56.0

98.0% tests passing for 12 rules, 1 rule has failing tests. Pull Request adding it to the conformance suite

3 tests are failing out of 150: haven't investigated the specific reasons for the failures yet.

[overlookmotel]

The 3 failing tests are due to what appears to be a bug in the no-unnecessary-waiting rule. This rule wouldn't work correctly with TS-ESLint either.

PR to fix: cypress-io/eslint-plugin-cypress#308

[overlookmotel]

eslint-plugin-regexp

Oxlint v1.56.0

99.9% tests pass for 82 rules. 1 rule has failing tests. Conformance tests snapshot

2 tests are failing out of 2370 - both due to regexp flags ordering in Oxc's AST (#20609). 19 tests are skipped.

[connorshea]

Two of the tests that fail right now are due to a minor discrepancy in the way that oxc handles ordering on regex flags. I've opened an issue for that here.

[overlookmotel]

@connorshea's PR to add this plugin to conformance tests suite is merged.

99.9% tests passing.

2 tests failing out of 2370 - both due to regexp flags ordering in Oxc's AST (#20609).

19 tests skipped due to containing /* exported */ comments (unsupported by Oxlint) and // eslint-disable comments (unsupported by RuleTester).

For anyone using older ESLint plugin versions (sonarjs <1.0, import <3.0) that still use context.getScope() - https://www.npmjs.com/package/oxlint-compat-wrapper proxies these from sourceCode. Also adds eslint-disable support for all JS plugins (fixes #20747).
