lefthook and package.json had parallel command definitions for the
same tools (oxlint, oxfmt, cspell). Consolidate by making lefthook
call the npm scripts, with staged files passed via the
LEFTHOOK_FILES env var. The scripts use ${LEFTHOOK_FILES:-<default>}
so they default to the full project when invoked manually and to
the staged-files list when invoked from lefthook.
Changes:
- package.json#check:oxlint: `oxlint ${LEFTHOOK_FILES:-src}`
(lints src/ manually; staged files from lefthook)
- package.json#check:oxfmt: `oxfmt --check ${LEFTHOOK_FILES:-src}`
- package.json#check:cspell: `cspell lint ${LEFTHOOK_FILES:-.}`
(walks CWD manually; staged files from lefthook)
- package.json#check:tsc, check📦 unchanged (no file args)
- lefthook.yml: file-filtered hooks (oxlint, oxfmt, cspell) now use
`sh -c 'LEFTHOOK_FILES="$0" npm run check:*' {staged_files}` to
inject the staged-files list into the env. sort-package-json and
typecheck call npm scripts directly (no file args).
- project-specs.md: document the unification pattern
Why sh -c + env var instead of the simpler 'npm run ... -- {staged_files}':
'oxlint src file.ts' lints the whole src/ tree *plus* file.ts
(oxlint doesn't dedupe paths). Setting LEFTHOOK_FILES as an env
var (which lefthook's 'env:' config does not template) requires
the sh -c wrapper, but it gives the right semantics: when the
var is set, only the explicit files are checked; when unset,
the default (src/ or .) is used.
Verified:
- 'npm run check:oxlint' (no env) lints all of src/
- 'LEFTHOOK_FILES=src/match.ts npm run check:oxlint' lints only that file
- 'npx lefthook run pre-commit' with a staged TS file: cspell output
shows '1/1 src/match.ts' (only staged file, not whole project)
- All 5 hooks pass on a real staged change
- 'lefthook validate' reports 'All good'
- 'npm run check' exits 0
The previous config was a hybrid of v1 (jobs: array) and v1
(top-level commands: block) that no longer validates under
lefthook 2.x. lefthook 2.0.0's schema has top-level 'commands:'
set to 'false'; the v1 jobs: array form still works, but the
orphan named-commands block at the top was silently invalid
(caught by 'lefthook validate').
Migrate to the v2-native 'commands:' (named) form under the hook:
pre-commit:
parallel: true
commands:
oxlint:
glob: ...
run: npx oxlint {staged_files}
...
Changes:
- Add 'min_version: 2.0.0' to declare the v2 schema explicitly
- Replace pre-commit.jobs: array with pre-commit.commands: (named)
- Inline the glob on each command (was a top-level property on each
job in v1)
- Remove the orphan top-level 'commands:' block — it was never
referenced by any hook, and v2 forbids it
- Update project-specs.md: drop the dangling reference to the
lefthook 'commands:' block (it was the dead top-level one);
describe the v2 commands: form
Verified:
- 'lefthook validate' reports 'All good'
- 'lefthook run pre-commit' executes all 5 hooks (oxlint, oxfmt,
sort-package-json, typecheck, cspell); globs correctly skip hooks
on non-matching files (e.g. lefthook.yml alone) and run them on
TS/JS changes
- 'npm run check' exits 0
- 'lefthook dump' shows the normalized v2 config
- Delete public/vite.svg, src/typescript.svg, src/style.css
- Empty public/ directory removed
- .npmignore: drop 'public/' entry (directory no longer exists), add
.oxlintrc.json and .oxfmtrc.json to ignore list
- cspell: add .oxfmtrc, .oxlintrc, .sortpackagerc to dictionary so
config-file name references aren't flagged
- lefthook: drop 'outdated' from pre-commit (kept in commands block for
explicit CI invocation); it shouldn't block commits for being behind on
upstream patch releases
- 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
