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

Pattern matching for TypeScript/ESM environments (F#-style, not regex).
Development
- Build:
npm run build - Test:
npm run test,npm run test:ci - Checks:
npm run check,npm run fix - Format/Fix:
npm run fix:oxfmt,npm run fix:oxlint
Tooling
- TypeScript 7 — type checker and build (
tsc). - node --test +
--experimental-strip-types— test runner (Node 22.6+, flag dropped on Node 24). - c8 — code coverage for
test:ci. - oxlint — Rust-based linter.
- oxfmt — Rust-based formatter (Prettier-compatible). Formats JS/TS, JSON/JSONC, YAML, Markdown, MDX, and more; built-in
package.jsonkey sorting replacessort-package-json. - cspell — spell checking.
- publint — validates
package.jsonfor ESM publishing correctness. Runs on publish only (in CI), not as part ofnpm run check. - @arethetypeswrong/cli (
attw) — validates.d.tsdeclarations against multiple module-resolution scenarios. Runs on publish only with--profile esm-only(the package is intentionally ESM-only). - lefthook — git pre-commit hooks.
Requirements
- Node.js >= 26 (engines field; pinned via
.node-version).
VSCode integration
- Recommended extensions: see
.vscode/extensions.json(oxc, cspell). - TypeScript 7 is used via the
typescriptteam.native-previewextension. - oxc extension provides oxlint squiggles and oxfmt format-on-save.
Workflows
- Version updates via
npm version. - Publishing via GitHub Actions on tagged commits (see
.github/workflows/ci.yml); thepublishjob runspublish:publintandpublish:attwbeforenpm publish.
Script prefix convention
Script names follow a prefix convention that signals when they run:
check:*— read-only verification. Aggregated bynpm run check. Used in pre-commit hooks and CI's build job.fix:*— mutating counterpart ofcheck:*. Run individually (nonpm run fixaggregator by design — fixes should be intentional, not batched).test:*— test scripts.npm run testruns the full suite;test:unit/test:ciare scope-specific variants.publish:*— runs only at publish time, in the CIpublishjob (immediately beforenpm publish). There is no localnpm run publishscript — publishing is CI-only by policy.
Contribution guidelines
- Commit signing (GPG).
- Set up commit message template:
npm run use:git-commit-message. - See
commit-message-template. - Type-only tests use
expect-type'sexpectTypeOf(...)insidenode --testcases.
