Summary

  • oxlint preset: only correctness is enabled by category. suspicious and pedantic switched on about 70 rules that @anolilab/eslint-config never enables. Every rule the preset turns on is now listed by name.
  • TypeScript jsdoc: the jsdoc rules are off for .ts/.tsx, as in @anolilab/eslint-config.
  • Parity: the rules @anolilab/eslint-config enables are now enabled in the preset wherever oxlint implements them: top level for TypeScript, **/*.{js,cjs,mjs,jsx} for JavaScript-only rules, **/*.{jsx,tsx} for jsx-a11y.
    • no-undef is left out because the preset sets no globals.
    • no-redeclare is JavaScript-only because it reports TypeScript interface merging.
    • react/jsx-no-bind is not in oxlint 1.89, so it stays ESLint-only.
  • eslint-config cleanup: removes deprecated and no-op rules (id-blacklist, jsx-quotes, lines-around-directive, vars-on-top, no-inner-declarations, the propTypes/defaultProps and class-layout React rules). Keeps one copy of each duplicate.
  • Formatting-only commit: style(eslint-config) takes the pre-commit formatter's output for react.ts and imports.ts, so the logic commit diffs only real changes. Ignore whitespace when reviewing.

Measured

  • packages/advisor/src with oxlint, type-aware off: 225 errors and 81 warnings before the preset changes, 13 and 61 after.
  • packages/studio/src: 5540 errors before, 5536 after. The four removed findings come from the jsx-a11y options now matching ESLint.
  • ESLint with the oxlint integration on: the same rules are enabled and disabled before and after.

Test plan

  • packages/eslint-config: build and vitest (29 tests)
  • packages/oxlint-config: vitest (13 tests) and tsc --noEmit. The new parity and jsdoc tests fail against the previous preset.
  • Fixture runs confirm the mirrored rules fire, and the TypeScript interface merge does not trigger no-redeclare.
  • Repo-wide lint:eslint not run on this branch.

Summary by CodeRabbit

  • Updates
    • Updated linting rules across JavaScript, TypeScript, React, Node.js, and import checks. Some checks are now disabled or no longer enforced, while others have adjusted severity or apply only to specific file types.
    • Oxlint now enables the correctness category without enabling the suspicious and pedantic categories. TypeScript, JavaScript, and JSX/TSX files have updated rule coverage.
  • Documentation
    • Updated the Oxlint configuration guide to reflect the current rule categories and file-specific settings.

…formatter

The committed files were not in the output of the pre-commit formatter, so
any later change to them reformatted unrelated lines. This commit takes the
formatter output as-is so the next change to these files diffs only what it
changes.

…uplicate

Removes rules that ESLint has deprecated or that do nothing with the options
we set: id-blacklist (no options, so it never reported), jsx-quotes and
lines-around-directive (formatting, left to the formatter), vars-on-top and
no-inner-declarations (no-op under no-var and ES2015 block scoping), and the
react class-layout and propTypes/defaultProps rules that TypeScript function
components never reach (prefer-es6-class, sort-comp, state-in-constructor,
static-property-placement, forbid-prop-types, forbid-foreign-prop-types,
sort-default-props).

Replaces no-new-object with no-object-constructor, and the Node core rules
global-require and no-path-concat with their n/ plugin equivalents. Drops
no-buffer-constructor, which unicorn/no-new-buffer already covers.

Where a core, sonarjs, e18e or import rule reports the same code as a unicorn
or regexp rule, only one copy stays on. The sonarjs copy is turned off because
it runs as a JS plugin.

…oc to JS

The suspicious and pedantic categories switched on every rule in those groups
that the preset does not list, about 70 rules that @anolilab/eslint-config
never enables. Those rules produced most of the findings on a TypeScript
package. The preset now lists each rule it turns on, and the correctness
category is the only one it sets.

ESLint turns the jsdoc rules off for .ts and .tsx files, and the preset did
not, so the same types were reported twice. The preset now does the same with
an override for TypeScript files.

The explicit switches follow the ESLint config: the rules that ESLint removed
are off here too, and so are the sonarjs copies of core and regexp rules.
unicorn/no-null, global-require and no-path-concat stay on, because ESLint
still enforces them and oxlint implements them natively.

Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
The preset listed only some of the rules @anolilab/eslint-config enables. The
rules below are now enabled with the same severity and options, wherever
oxlint implements them and ESLint enables them in that file kind:

- top level: rules ESLint enables for TypeScript files
- **/*.{js,cjs,mjs,jsx}: rules ESLint enables only for JavaScript files
- **/*.{jsx,tsx}: the jsx-a11y rules, which ESLint enables for JSX files

no-undef is left out. It needs the globals ESLint sets, and the preset sets
none, so it would report every browser and Node global. no-redeclare is only
enabled for JavaScript, because it reports TypeScript interface merging.

The jsx-a11y options follow ESLint, so custom components are no longer flagged
by no-autofocus and some interactive roles are allowed. react/jsx-no-bind is not
in oxlint 1.89, so it stays ESLint-only.

📝 Walkthrough

The ESLint configuration changes rule selections, import handling, and React settings. The Oxlint configuration changes rule severities and file-kind overrides. Its README and tests reflect selected configuration changes.

Changes: ESLint and plugin rule settings

Layer / File(s) Summary
ESLint rule selections
packages/eslint-config/src/config/best-practices.ts, errors.ts, plugins/e18e.ts, plugins/sonarjs.ts, style.ts, plugins/node.ts
Several rules were removed, disabled, or renamed. The Node configuration now uses n/global-require and n/no-path-concat.
Import rules and resolver configuration
packages/eslint-config/src/config/plugins/imports.ts
The import extension rule turns off when rewriteRelativeImportExtensions is enabled. The TypeScript resolver branches remain conditional on tsconfigPath. Conditional spreads were parenthesized, and import/no-named-default was removed.
React ESLint configuration
packages/eslint-config/src/config/plugins/react.ts, packages/eslint-config/src/config/plugins/oxlint-react-doctor.ts
Several React rules and two counterpart mappings were removed. Conditional spreads were parenthesized. The React Refresh allowlists and plugin-version condition remain unchanged.

Oxlint configuration

Oxlint rules and file-kind overrides
packages/oxlint-config/.oxlintrc.json, packages/oxlint-config/README.md, packages/oxlint-config/__tests__/index.test.ts, packages/oxlint-config/src/bin.mts
The configuration changes rule severities and adds TypeScript, JavaScript, and JSX/TSX overrides. The README and tests reflect the updated categories, rules, and overrides. The CLI’s eslint-disable-next-line no-console comments were removed; its runtime behavior is unchanged.

Preserve import/extensions checks for JavaScript.

When rewriteRelativeImportExtensions is enabled, the all-files rule is turned off. The later override only targets TypeScript files, so JavaScript files lose their extension diagnostics. Keep the base rule enabled and retain the existing TypeScript override.

The lockfile resolved @anolilab/eslint-config 30.0.7 and
@anolilab/prettier-config 10.0.4 while a manifest in the workspace
declares 31.0.0 and 11.0.0. CI installs with --frozen-lockfile, so the
job failed with ERR_PNPM_OUTDATED_LOCKFILE before running any tests.

…s anything

The package depends on oxlint, so @anolilab/eslint-config 31 turns off its
ESLint no-console rule for these files, and the five eslint-disable comments
in bin.mts reported "Unused eslint-disable directive". The rule is still
enforced by the preset for consumers.
