@kentcdodds/typecheck-modules

Typecheck one or more TypeScript files while resolving the TypeScript version
from the target module(s), not from this CLI.

Install

``sh
npm install -D @kentcdodds/typecheck-modules
`

Usage

`sh
npx @kentcdodds/typecheck-modules
typecheck-modules
node ./cli.js
`

Examples:

`sh
typecheck-modules ./playground
typecheck-modules ./playground/index.ts
typecheck-modules "./playground/*/.{ts,tsx}"
typecheck-modules --ignore "*/.test.ts" ./playground
`

$3

- Resolves typescript from the nearest node_modules above each module
(using the closest package.json when available).
- If a tsconfig.json is found, it uses those compiler options.
- If no tsconfig.json is found, it falls back to TypeScript defaults and
warns once per directory group (similar to tsc file.ts behavior).
- Accepts directories and searches recursively for .ts and .tsx.
- Accepts globs cross‑platform (no shell expansion required).

$3

By default, these are ignored during directory and glob expansion:

- node_modules, .git, dist, build, out, .cache, coverage,
test-output, test-results, test-reports

Provide --ignore to replace the defaults entirely:

`sh
typecheck-modules --ignore "*/.test.ts" ./playground
typecheck-modules --ignore "/fixtures/" "./playground/*/.ts"
``
