lint-staged

Try it in 3 steps

1. 1

   Install the checking tools as development dependencies

   Use Node.js 22.22.1 or newer in a new disposable Git/npm test project or test branch with at least one commit. The following step creates configuration files.

   npm install --save-dev lint-staged@17.6.0 eslint@9Copy
2. 2

   Configure ESLint and lint-staged

   Create a minimal ESLint flat config and a lint-staged config that fixes staged JavaScript from the project root.

   cat > eslint.config.mjs <<'EOF' export default [{ files: ["**/*.js"], rules: { semi: ["error", "always"] } }] EOF cat > lint-staged.config.mjs <<'EOF' export default { "*.js": "eslint --fix" } EOFCopy
3. 3

   Stage a real file and run the check

   Confirm that ESLint adds the semicolon and lint-staged stages the task change. By default it creates a backup stash for tracked state, so test on a clean disposable branch.

   printf 'const answer = 42\n' > lint-demo.js git add lint-demo.js eslint.config.mjs lint-staged.config.mjs package.json package-lock.json npx lint-stagedCopy
