- Add .node-version (single line: '26') so fnm/nvm/volta/mise and the
VS Code Node version manager extension auto-switch when entering the
project directory
- engines.node in package.json: bump from '>=22.6' to '>=26' (npm-side
install-time declaration)
- Drop --experimental-strip-types flag from node --test invocations:
Node 26 has --strip-types unflagged
- .github/workflows/ci.yml: switch from hard-coded node-version: 24 to
node-version-file: .node-version in both build and publish jobs so CI
follows the .node-version file (single source of truth)
- .npmignore: add .node-version (developer-tool file, not for publish)
- .vscode/settings.json: pin js/ts.tsdk.path to node_modules/typescript/lib
so the editor uses the project's TS 7, not a different global install
- .vscode/extensions.json: swap ms-vscode.vscode-typescript-next for
typescriptteam.native-preview (the official TS team extension that
ships nightly TS support, including TS 7)
- cspell: add 'esbenp' and 'typescriptteam' to dictionary
- package-lock.json: regenerated for engines.node >=26
tsconfig.json target/lib are unchanged: es2024 is the highest stable ES
target TS 7.0.2 ships, and Node 26 supports all ES2024 features natively.
- Install expect-type@1.4.0 (devDependency)
- New src/index.test.ts exercises the public API with both runtime
assertions (node:assert/strict inside node:test) and type-level
assertions (expectTypeOf().toEqualTypeOf, toMatchTypeOf, toHaveProperty)
- Tests are excluded from tsc -p tsconfig.build.json (no .d.ts pollution
in dist/)
- Type-level checks happen during tsc --noEmit (run by 'npm run check' and
the test script); expectTypeOf assertions have no runtime side effect,
so they pair naturally with node --test in the same test() blocks
- cspell: add EDITMSG to dictionary (used in commit-message-template path)
- oxlint test-file overrides: silence no-nodejs-modules (we use node:
builtins) and no-magic-numbers (literals in tests are fine)
Coverage:
- match() returns a builder with with/exhaustive/otherwise
- P.literal narrows to its literal type, P.type to its typeof target
- exhaustive() returns the union of handler return types
- otherwise() falls back when no case matches
- exhaustive() throws when no case matches
- 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
