Setup Pre-Commit Hooks
What This Sets Up
- Husky pre-commit hook
- lint-staged 对所有 staged files 运行 Prettier
- Prettier config(如果缺失)
- pre-commit hook 中的 typecheck 和 test scripts
Steps
1. Detect package manager
检查 package-lock.json (npm)、pnpm-lock.yaml (pnpm)、yarn.lock (yarn)、bun.lockb (bun)。使用存在的那个。不清楚时默认 npm。
2. Install dependencies
作为 devDependencies 安装:
husky lint-staged prettier
3. Initialize Husky
npx husky init
这会创建 .husky/ dir,并向 package.json 添加 prepare: "husky"。
4. Create .husky/pre-commit
写入这个文件(Husky v9+ 不需要 shebang):
npx lint-staged
npm run typecheck
npm run test
Adapt:把 npm 替换为检测到的 package manager。如果 repo 的 package.json 没有 typecheck 或 test script,就省略对应行并告知用户。
5. Create .lintstagedrc
{
"*": "prettier --ignore-unknown --write"
}
6. Create .prettierrc (if missing)
只有没有 Prettier config 时才创建。使用这些 defaults:
{
"useTabs": false,
"tabWidth": 2,
"printWidth": 80,
"singleQuote": false,
"trailingComma": "es5",
"semi": true,
"arrowParens": "always"
}
7. Verify
-
.husky/pre-commit存在且可执行 -
.lintstagedrc存在 - package.json 中的
preparescript 是"husky" - prettier config 存在
- 运行
npx lint-staged验证可用
8. Commit
Stage 所有 changed/created files,并用 message 提交:Add pre-commit hooks (husky + lint-staged + prettier)
这会经过新的 pre-commit hooks,是一个不错的 smoke test。
Notes
- Husky v9+ 不需要 hook files 中的 shebangs
prettier --ignore-unknown会跳过 Prettier 无法 parse 的 files(images 等)- pre-commit 先运行 lint-staged(快,只针对 staged files),再运行完整 typecheck 和 tests
