Activates type-aware rules via oxlint --type-aware, backed by
oxlint-tsgolint (TypeScript-Go). Catches unsafe type assertions,
unnecessary type parameters, and other issues regular oxlint
cannot see.
- Add oxlint-tsgolint devDep + 6 platform-specific native bindings
as optionalDependencies (same pattern as oxlint)
- Add --type-aware flag to check:oxlint
- Add 6 @oxlint-tsgolint/* platforms to check:outdated ignore list
- Disable 3 type-aware rules in .oxlintrc.json with rationale:
- typescript/no-unsafe-type-assertion, typescript/no-unnecessary-type-parameters:
fire on legitimate generic type machinery in keysMatch/MatchBuilder
that needs type-system restructuring (deferred to a follow-up)
- typescript/no-floating-promises in test files: expectTypeOf() is
a sync type-assertion library that oxlint-tsgolint misidentifies
Code simplifications enabled by the new strict checks:
- src/match.ts: drop value as unknown casts (T is already assignable
to unknown) and the redundant run(value) as R cast
- src/index.test.ts: drop unnecessary 'X' as 'X | Y' assertions in
match<...>(...) calls (literals are already assignable to the union)
Documentation updates in project-specs.md and README.md. Add
'tsgolint' to cspell word list.
- Add check:knip using --include dependencies,exports,files
(skips the noisy 'types' category, which produces false positives
for libraries whose exported types are part of the public API)
- Remove tslib and type-fest (both caught as unused by knip)
- Add 'knip' to cspell word list
- No knip config file: the --include flag keeps the scope targeted
without boilerplate, matching the 'keep it simple' principle
- Document in project-specs.md (CHECK section) and README.md
Validates the emitted .d.ts declarations against multiple TypeScript
module-resolution scenarios. Same rationale as publint: it validates
the publishable artifact, not the source, so it belongs in the
publish: prefix, not check:.
- Add publish:attw script using --profile esm-only (the package is
intentionally ESM-only; CJS resolution is out of scope by design)
- Add step to CI publish job, after publish:publint and before
npm publish
- Document the script and the esm-only rationale in project-specs.md
and README.md
- Add 'attw' and 'arethetypeswrong' to cspell word list
- Remove unused 'stricter' word that was added speculatively before
publint validates the publishable artifact (dist/ vs package.json),
not the source. It should run only at publish time, in the CI publish
job, not on every commit.
- Rename check:publint -> publish:publint
- Remove from 'check' chain
- Add 'publish:publint' as a step in the CI publish job, right
before 'npm publish'
- Introduce a 'publish:' script prefix for publish-time-only scripts
- Document the prefix convention (check:, fix:, test:, publish:)
in project-specs.md (as a top-level subsection under Scripts)
and in the README
- Add 'publint' and 'stricter' to cspell word list
A new script should pick the prefix that matches its lifecycle, not
invent a new one. The 'publish:' prefix has no 'npm run publish'
aggregator by design (publishing is CI-only).
project-specs.md:
- Replace Prettier/ESLint/Vite/Vitest references with oxfmt/oxlint/oxc
and TypeScript 7 / node --test
- Drop @tsconfig/strictest note; rules are inlined in tsconfig.json,
enumerated explicitly
- Document oxlint rule disables (no-undefined, sort-keys, id-length,
no-named-export) and test-file overrides (no-unused-expressions,
no-empty-file, no-nodejs-modules, no-magic-numbers)
- Document Node 26 / .node-version / engines.node / CI follow
- Document allowImportingTsExtensions + rewriteRelativeImportExtensions
for the node --strip-types quirk
- Replace Vite/vitest coverage example with c8 + node --test
- Sync scripts section: drop check:eslint, check:prettier and their
fix:* counterparts; add check:oxlint/check:oxfmt/fix:oxlint/fix:oxfmt
- Add current source layout (index.ts, match.ts, pattern.ts, index.test.ts)
- Update VSCode integration section with actual settings.json and
extensions.json contents
- Document the actual commit history with gitmoji prefixes
- Fix 'initilizing' typo
- Drop 'changesets is a devDep' claims (changesets is not installed)
package.json:
- Move @oxfmt/binding-* and @oxlint/binding-* from devDependencies to
optionalDependencies so the right binding is selected per platform
(CI on Ubuntu gnu gets the gnu binding automatically, not the
local musl one)
- Extend check:outdated to ignore the platform-specific bindings (they
show as 'not installed' on the current platform, which is correct
- Add cspell words: gitmoji, dbaeumer, msvc (the latter for the Windows
binding variant). Drop the unused 'nocheck' word
README.md:
- Drop the 'changesets is available as a devDep' line; changesets
isn't installed
- Drop .eslintrc.cjs and .prettierrc, add .oxlintrc.json and .oxfmtrc.json
- oxlint covers correctness/suspicious/perf/style/restriction categories
plus import and typescript plugins; oxfmt reads the same .prettierrc-style
options we had before
- Update lefthook.yml pre-commit jobs to run oxlint/oxfmt instead of
eslint/prettier
- Update .vscode/extensions.json (oxc replaces eslint/prettier/vitest) and
settings.json (oxc becomes the default formatter for TS/JS)
- Add 'oxlint', 'oxfmt', 'oxc', 'nodenext' to cspell dictionary
- Rewrite README 'Development' section to describe the new toolchain
