ci(frontend): migrate Prettier → oxfmt, add oxlint as a blocking gate - #247
Conversation
Formatting moves from Prettier to oxfmt (Rust; native for js/ts/json/css/scss, bundled Prettier for .vue/.md), and oxlint joins ESLint as a second linter. - `.oxfmtrc.json` translates `.prettierrc.js` 1:1 (printWidth 120, tabWidth 2, semi, double quotes, trailingComma es5) and absorbs `.prettierignore`, both of which are deleted. `demo/` is newly ignored so format scope matches the ESLint ignore list; `sortPackageJson` is off to keep package.json key order stable. - `.oxlintrc.json` is generated by `@oxlint/migrate` from eslint.config.mjs. Its `jsPlugins` bridge for @intlify/eslint-plugin-vue-i18n is dropped: oxlint has no Vue template parser, so those rules fired "use the latest vue-eslint-parser" on every SFC. ESLint keeps owning template + i18n rules. - eslint.config.mjs swaps eslint-plugin-prettier/recommended for a direct eslint-config-prettier, and adds oxlint.buildFromOxlintConfigFile() so a finding is not reported twice. ESLint warnings drop 2349 -> 1291; errors stay 0. - CI gains blocking `format:check` and `lint:oxc` steps; the ESLint step stays continue-on-error because of the pre-existing advisory warnings. - pre-commit gains a blocking `frontend-format` hook; the stale `frontend-eslint`, `frontend-prettier` and `helmlint` ci.skip entries named hooks that don't exist.
Mechanical `npx oxfmt` run over extralit-frontend (744 files). The .ts/.vue
sources were already Prettier-clean and are almost untouched; the churn is in
the file types the old `prettier --write "**/*.{ts,vue}"` glob never covered —
.js specs, .scss/.css, .md and the extension's popup.html.
`static/` is added to ignorePatterns: it holds served-verbatim assets, and
oxfmt was expanding the vendored handlebars.min.js bundle.

📝 WalkthroughWalkthroughThe frontend toolchain now uses Oxfmt for formatting, Oxlint for gating lint checks, and ESLint for advisory Vue and i18n checks. CI and pre-commit hooks were updated. Existing source, tests, documentation, and changelog content was reformatted. ChangesFrontend quality toolchain
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This PR makes formatting and oxlint blocking in CI and adds a pre-commit formatter; the current hook omits HTML, so extension/popup.html can pass local checks but fail the CI formatting gate, and one edited migration risk-register row contradicts the documented plugin order. These are bounded follow-ups rather than runtime defects, so the PR is mergeable with explicit owner awareness. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- The `frontend-format` pre-commit hook's file pattern omitted `html`, so `extension/popup.html` could be committed unformatted and then fail the blocking CI `format:check`. oxfmt 0.64 formats HTML via bundled Prettier. (CodeRabbit, PR #247) - Restores the in-editor formatting loop that removing eslint-plugin-prettier took away: `oxc.oxc-vscode` replaces `esbenp.prettier-vscode`, scoped by language so ruff keeps owning Python. `sibiraj-s.vscode-scss-formatter` goes too — oxfmt now owns .scss and CI gates it, so a second formatter would fight it on save.
Why
Frontend formatting was Prettier, wired two ways: an
npm run formatscript scoped to**/*.{ts,vue}, andeslint-plugin-prettiersurfacingprettier/prettieras an ESLint warning. Neither gated anything — the CI lint step iscontinue-on-error: trueand there was noformat:checkstep at all.Baseline on
main:eslint .reports 0 errors, 2349 warnings — 687 of themprettier/prettier. ~29% of all lint output was formatting noise a formatter should own.This moves formatting to oxfmt (Rust; native for js/ts/json/css/scss, bundled Prettier for
.vue/.md), makes it a blocking CI check, adds an oxfmt pre-commit hook, and adopts oxlint as a second, fast, blocking linter alongside ESLint.What changed
Dependencies — out:
prettier,eslint-plugin-prettier. In:oxfmt@0.64,oxlint@1.79,eslint-plugin-oxlint.eslint-config-prettieris kept and now imported directly (it previously only arrived transitively viaeslint-plugin-prettier/recommended)..oxfmtrc.json— generated byoxfmt --migrate=prettier; all five.prettierrc.jsoptions map 1:1 (printWidth 120, tabWidth 2, semi, double quotes,trailingComma: es5)..prettierrc.jsand.prettierignoreare deleted. Two additions toignorePatterns:demo— ESLint already ignores it; this aligns format scope with lint scope (Prettier was formattingdemo/video/**/*.ts).static— served-verbatim assets; oxfmt was expanding the vendoredhandlebars.min.jsbundle.sortPackageJsonis left off sopackage.jsonkey order stays stable..oxlintrc.json— generated by@oxlint/migratefromeslint.config.mjs(128 rules ported, 73 skipped as nursery/unimplemented/unsupported). ItsjsPluginsbridge for@intlify/eslint-plugin-vue-i18nis removed: oxlint has no Vue template parser yet, so every one of those rules fired"use the latest vue-eslint-parser"on every SFC. ESLint keeps owning template + i18n rules — this is a deliberate dual-linter setup, not a transitional state.eslint.config.mjs—eslint-plugin-prettier/recommendedand theprettier/prettierrule are gone;...oxlintPlugin.buildFromOxlintConfigFile(".oxlintrc.json")andeslintConfigPrettiergo last so no finding is reported by both linters.Scripts
lint:fixhad to be spelled out — the oldnpm run lint -- --fixtrick breaks oncelintis a two-command chain.CI (
.github/workflows/extralit-frontend.yml) — new blockingCheck formatting 🎨andRun oxlint 🦀steps. The ESLint step keepscontinue-on-error: truebecause of its ~1300 pre-existing advisory warnings.pre-commit — new blocking
frontend-formathook (oxfmt over staged frontend files), reusing the existing hook's path-prefix-stripping idiom. The advisoryfrontend-linteslint hook is unchanged. Also removed three staleci.skipentries (frontend-eslint,frontend-prettier,helmlint) that named hooks which don't exist.The reformat commit

It touches 27 files: the.ts/.vuesources were already Prettier-clean and barely move — the churn is entirely in file types the old{ts,vue}glob never covered (.jsspecs, scss/css, markdown,extension/popup.html).Verification
