Lefthook

Name: lefthook
Author: terminalskills

Overview

Lefthook is a fast, polyglot Git hooks manager. Unlike Husky, it doesn't require Node.js — works with any language. Runs hooks in parallel, supports glob patterns, and configures via YAML.

Instructions

Step 1: Install

npm install -D lefthook
npx lefthook install
# Or: brew install lefthook

Step 2: Configure

# lefthook.yml — Git hooks configuration
pre-commit:
  parallel: true
  commands:
    lint:
      glob: "*.{ts,tsx,js,jsx}"
      run: npx eslint --fix {staged_files}
    format:
      glob: "*.{ts,tsx,js,jsx,css,md,json}"
      run: npx prettier --write {staged_files}
    typecheck:
      run: npx tsc --noEmit

pre-push:
  commands:
    test:
      run: npm test

commit-msg:
  commands:
    commitlint:
      run: npx commitlint --edit {1}

Guidelines

Lefthook runs commands in parallel by default — faster than sequential Husky hooks.
{staged_files} placeholder only passes staged files — no need for lint-staged.
Works in polyglot repos (Go, Python, Ruby) without Node.js dependency.
