设置 Pre-Commit 钩子

将要设置的内容

  • Husky pre-commit 钩子
  • lint-staged 对所有暂存文件运行 Prettier
  • Prettier 配置(如果缺失)
  • typecheck 和 test 脚本在 pre-commit 钩子中运行

步骤

1. 检测包管理器

检查 package-lock.json(npm)、pnpm-lock.yaml(pnpm)、yarn.lock(yarn)、bun.lockb(bun)。使用已存在的那个。如果不确定,默认使用 npm。

2. 安装依赖

安装为 devDependencies:

husky lint-staged prettier

3. 初始化 Husky

npx husky init

这会创建 .husky/ 目录并在 package.json 中添加 prepare: "husky"。

4. 创建 .husky/pre-commit

写入以下内容(Husky v9+ 不需要 shebang):

npx lint-staged
npm run typecheck
npm run test

适配:将 npm 替换为检测到的包管理器。如果仓库的 package.json 中没有 typecheck 或 test 脚本,则省略对应行并告知用户。

5. 创建 .lintstagedrc

{
  "*": "prettier --ignore-unknown --write"
}

6. 创建 .prettierrc(如果缺失)

仅当不存在 Prettier 配置时才创建。使用以下默认值:

{
  "useTabs": false,
  "tabWidth": 2,
  "printWidth": 80,
  "singleQuote": false,
  "trailingComma": "es5",
  "semi": true,
  "arrowParens": "always"
}

7. 验证

  • .husky/pre-commit 存在且可执行
  • .lintstagedrc 存在
  • package.json 中的 prepare 脚本为 "husky"
  • prettier 配置存在
  • 运行 npx lint-staged 验证其是否正常工作

8. 提交

暂存所有更改/创建的文件,并使用消息提交:Add pre-commit hooks (husky + lint-staged + prettier)

这将触发新的 pre-commit 钩子执行:是一个很好的冒烟测试,验证一切正常。

注意事项

  • Husky v9+ 不需要在钩子文件中加 shebang
  • prettier --ignore-unknown 会跳过 Prettier 无法解析的文件(如图片等)
  • pre-commit 钩子先运行 lint-staged(快速,仅处理暂存文件),然后运行完整的 typecheck 和 test

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
