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- Add 6 @oxlint-tsgolint/* platforms to check:outdated ignore list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.

|
|
|
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.
|
|
- **oxlint-tsgolint** — type-aware linting via typescript-go (powers `--type-aware` in `oxlint`). Catches unsafe type assertions, unnecessary type parameters, and other type-system issues that regular oxlint can't see.
|
|
- **oxfmt** — Rust-based formatter (Prettier-compatible). Formats JS/TS, JSON/JSONC, YAML, Markdown, MDX, and more; built-in `package.json` key sorting replaces `sort-package-json`.
|
|
- **cspell** — spell checking.
|
|
- **knip** — finds unused dependencies, exports, and files. Scoped via `--include dependencies,exports,files` to skip the noisy `types` category (which produces false positives for libraries whose exported types are part of the public API).
|
|
- **publint** — validates `package.json` for ESM publishing correctness. Runs on publish only (in CI), not as part of `npm run check`.
|
|
- **@arethetypeswrong/cli** (`attw`) — validates `.d.ts` declarations 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-preview` extension.
|
|
- 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`); the `publish` job runs `publish:publint` and `publish:attw` before `npm publish`.
|
|
|
|
## Script prefix convention
|
|
|
|
Script names follow a prefix convention that signals _when_ they run:
|
|
|
|
- `check:*` — read-only verification. Aggregated by `npm run check`. Used in pre-commit hooks and CI's build job.
|
|
- `fix:*` — mutating counterpart of `check:*`. Run individually (no `npm run fix` aggregator by design — fixes should be intentional, not batched).
|
|
- `test:*` — test scripts. `npm run test` runs the full suite; `test:unit` / `test:ci` are scope-specific variants.
|
|
- `publish:*` — runs only at publish time, in the CI `publish` job (immediately before `npm publish`). There is no local `npm run publish` script — 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`'s `expectTypeOf(...)` inside `node --test` cases.
