After dropping project-specs.md last commit, three categories of
content were lost that have no other home in the repo:
1. The script prefix convention with its 'pick the right prefix,
don't invent one' rule
2. The feedback-tier system (table + 'why these splits?')
3. The publishing workflow (tagged-release flow)
These are maintainer/contributor-facing material, not user-facing.
The standard OSS location for this kind of doc is CONTRIBUTING.md,
which keeps it separate from README.md (user docs) so the two
don't drift. README.md gains a pointer at the bottom.
The content is condensed: no config dumps, no restatements of
package.json, no historical commit-message examples. Only the
rationale that isn't already in the actual config files.
project-specs.md was a parallel document that restated most of what was
already in package.json, README.md, and the config files themselves.
The only content that wasn't already captured elsewhere was the
'why' behind a handful of non-obvious tooling choices, which now
lives in README.md as a new 'Tooling decisions' subsection.
This eliminates the drift problem between the two docs (the source
of drift in the previous commit) by having one source of truth for
'what' (the config files) and one source for 'why' (README).
Override the prior design choice: there is now an npm run fix
script that runs fix:oxlint && fix:oxfmt. Rationale: the friction
of having to remember and run two separate fix commands after
npm run check outweighs the 'intentional fixes' argument once
check has already told you which fixers are needed. The diff
after running fix remains the review surface.
- package.json: new 'fix' script (npm run fix:oxlint && npm run fix:oxfmt)
- project-specs.md: updated the FIX section to document the new
aggregator, removed the 'no fix aggregator by design' text in
two places (FIX section and PREFIX CONVENTION section)
- README.md: same updates, plus the Development section header
changed from 'Format/Fix' to 'Individual fixes' to reflect
the new hierarchy
Cleaner separation of concerns:
- options.typeAware: true in .oxlintrc.json activates type-aware
rules declaratively (equivalent to --type-aware CLI flag, but
the script command stays clean: just 'oxlint ...')
- Remove the 3 type-aware rule disables from .oxlintrc.json
- Add source-level oxlint-disable directives instead:
- 4x typescript/no-unsafe-type-assertion (pattern.ts: keysMatch
Object.keys() cast, candidate[] cast; structuralMatcher value
as S cast; match.ts: handler as ... cast in nextCases)
- 1x typescript/no-unnecessary-type-parameters (pattern.ts:
keysMatch <S extends object>)
- 1x file-level typescript/no-floating-promises in index.test.ts
(expectTypeOf() is a sync type-assertion library that the
type-aware linter misidentifies)
Disabling rules at the source (next to the line that needs the
exemption) documents intent more clearly than a global config
override, and makes the trade-off visible to anyone reading the
code. Re-enabling a rule in the future only requires removing the
inline comment, not editing a central config.
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
