lint-staged-tsc

library0.2.1jsnpmunverified

A utility that extends lint-staged to run TypeScript type checking only on staged files, improving performance by avoiding full project rechecks. Currently at stable v0.2.1 with intermittent releases (last in May 2022). The key differentiator is that unlike tsc --noEmit on all files, it scopes type checking to the staged files, respecting tsconfig include and declarations. Minimal dependencies but requires lint-staged as peer. Suitable for CI and pre-commit hooks.

Debug

Known issues

gotchaThis tool requires TypeScript to be installed as a devDependency. It uses the local tsc binary.

fix

Ensure typescript is in devDependencies (npm i -D typescript).

affects: >=0.0.2

gotchaThe tool relies on the tsconfig.json include/exclude configuration. If your tsconfig doesn't cover staged files, type checking may be skipped.

fix

Verify that tsconfig.json includes the staged files. Adjust include patterns if needed.

affects: >=0.0.2

gotchaThis is not a replacement for full tsc --noEmit. It only checks staged files; errors in non-staged files will not be caught until they are staged.

fix

Consider running full type check in CI or periodically.

affects: >=0.0.2

deprecatedProject has seen no updates since May 2022. May not support newer TypeScript versions or lint-staged breaking changes.

fix

Monitor for updates or consider alternatives like tsc-files or custom lint-staged task.

affects: >=0.2.1
