lint-staged-git-hook

name	lint-staged-git-hook
description	lint-staged pre-commit hook for running linters only on Git-staged files. Pattern-matched task runners, auto-fix before commit, integration with husky, and staged-only analysis to minimize CI overhead. Sources: okonet/lint-staged (MIT).

/lint-staged-git-hook

When to Use

• Run ESLint/Prettier/ktlint only on files being committed (not the whole repo)
• Auto-fix formatting before commit so developers never push bad style
• Yamtam hook layer: run security checks on staged files only to keep hooks fast
• Monorepo: pattern-match different tools per package directory

Do NOT use for

• Full CI pipeline analysis (lint-staged runs only on staged files, not all changed files in a PR)
• Post-commit hooks (use [[merkle-tree-audit]] for post-commit integrity)

Setup

npx husky init
echo "npx lint-staged" > .husky/pre-commit
