目录

• 1. 初始化vite项目
• 2. 添加eslint
• 3. 添加 prettier
• 4. 添加 husky和lint-staged
• 5. 配置commitlint

✔ Select a framework: › react  // 选择框架
✔ Select a variant: › react-ts // 选择组合

2. 添加eslint

解决eslint报错

Missing semicolon.eslint: 末尾加上;即可

JSX not allowed in files with extension '.tsx': 在.eslintrc.json中添加rules设置

{
    // ...
    "react/jsx-filename-extension": [
        "error",
        {
            "extensions": [".js", ".jsx", ".tsx", ".ts"]
        }
    ]
};

{count} must be placed on a new line: 代码换行即可；

Unable to resolve path to module './App': 在.eslintrc.json中添加rules设置

{
    // ...
    rules: {
         "import/no-unresolved": "off",
         "import/extensions": "off",
         "import/no-absolute-path": "off"
    },
};

'vite' should be listed in the project's dependencies, not devDependencies.:

在.eslintrc.json中添加rules设置

{
    // ...
    "rules": {
        "import/no-extraneous-dependencies": [
            "error", 
            {"devDependencies": true}
        ]
        // ...
    }
};

3. 添加 prettier

安装

npm i -D prettier eslint-config-prettier eslint-plugin-prettier

prettier: 核心模块

eslint-config-prettier: 关闭所有不必要或可能跟prettier产生冲突的规则

eslint-plugin-prettier: 可以让eslint使用prettier规则进行检查

配置

根目录下.eslintrc.json文件中添加extends设置

{
    // ...
    "extends": [
        // ...
        "plugin:prettier/recommended",
    ],
}

根目录下创建.prettierrc.json文件

{
  "trailingComma": "es5",
  "tabWidth": 2,
  "semi": true,
  "singleQuote": true
}

注意⚠️：

修改.prettierrc.json文件后，需要重启vscode才生效

如果配置后，配置不生效，尝试以下设置：

4. 添加 husky和lint-staged

安装

npm i -D lint-staged husky

配置

在package.json中添加脚本

npm set-script prepare "husky install"

package.json文件的scripts中，就会自动添加prepare；

2. 初始化husky,将 git hooks钩子交由husky执行

npm run prepare

会在根目录创建.husky文件夹

3. 配置package.json

package.json文件如下：

{
  "env": {
    "browser": true,
    "node": true,
    "es2021": true
  },
  "extends": [
    "plugin:react/recommended",
    "airbnb",
    "plugin:prettier/recommended",
    "plugin:import/recommended"
  ],
  "parser": "@typescript-eslint/parser",
  "parserOptions": {
    "ecmaFeatures": {
      "jsx": true
    },
    "ecmaVersion": "latest",
    "sourceType": "module"
  },
  "plugins": ["react", "@typescript-eslint"],
  "rules": {
    "import/no-extraneous-dependencies": [
      "error", 
      {"devDependencies": true}
    ],
    "react/jsx-filename-extension": [
      "error",
      {
        "extensions": [".js", ".jsx", ".tsx", ".ts"]
      }
    ],
    "import/no-unresolved": "off",
    "import/extensions": "off",
    "import/no-absolute-path": "off"
  }
}

添加钩子pre-commit

npx husky add .husky/pre-commit "npx lint-staged"

5. 配置commitlint

• 作用：规范提交信息
• 格式：git commit -m '类型: 描述性文字'

类型概念build编译相关的修改，例如发布版本、对项目构建或者依赖的改动ci持续集成修改docs文档修改feat新特性、新功能fix修改bugperf优化相关，比如提升性能、体验refactor代码重构revert回滚到上一个版本style代码格式修改, 注意不是 css 修改test测试用例修改chore其他修改，比如改变构建流程、或者增加依赖库、工具等

• 安装

npm i -D commitlint @commitlint/config-conventional

• 配置

package.json中配置commitlint

{
    // ...
    "commitlint": {
        "extends": [
            "@commitlint/config-conventional"
        ]
    }
}

• 添加钩子

npx husky add .husky/commit-msg 'npx --no-install commitlint --edit "$1"'

git commit 就会触发提交规范的校验啦;
