create-react-app 初始化 React 工程，配置工具链，以及如何改多页应用

初始化工程

• 执行create-react-app脚本

  npx create-create-app levi-web --template typescript

• 打开项目，整理目录，删除自动化测试的相关包和文件，修缮package.json

工具链配置

• 添加huksy做提交前的各种操作

  yarn add husky --dev

  yarn husky install

  npm set-script prepare "husky install" // 此处需要npm7+，7以下可手动设置

• 添加commitlint，规范commit-msg

  yarn add @commitlint/config-conventional @commitlint/cli -D

  echo "module.exports = {extends: ['@commitlint/config-conventional']}" > commitlint.config.js

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

• 添加prettier,让代码更美观

  yarn add --dev --exact prettier

  echo {}> .prettierrc.json

  // .prettierrc.json(参考)
  {
    "arrowParens": "always",
    "bracketSameLine": false,
    "bracketSpacing": true,
    "embeddedLanguageFormatting": "auto",
    "htmlWhitespaceSensitivity": "css",
    "insertPragma": false,
    "jsxSingleQuote": false,
    "printWidth": 80,
    "proseWrap": "preserve",
    "quoteProps": "as-needed",
    "requirePragma": false,
    "semi": false,
    "singleQuote": false,
    "trailingComma": "es5",
    "useTabs": false,
    "vueIndentScriptAndStyle": false,
    "tabWidth": 2
  }

  // .prettierignore 
  build
  coverage

  npm set-script lint "prettier --write ." // 此处同样需要npm7+

  yarn add lint-staged -D

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

  // package.json
  {
      "lint-staged": {
          "**/*": "prettier --write --ignore-unknown"
      }
  }

• 修改eslint,使其能够和prettier更好的配合

  yarn add eslint-config-prettier eslint-plugin-prettier -D

  // package.json
  "eslintConfig": {
    "extends": [
      ...
      "prettier", // It turns off all ESLint rules that are unnecessary or might conflict with Prettier
      "plugin:prettier/recommended" // Runs Prettier as an ESLint rule and reports differences as individual ESLint issues.
    ]
  },

• 配置stylelint(暂时先不要吧，后续看情况补充)

• vscode配置settings.json(工作区)
  通过此配置，代码保存的时候自动执行eslint的修复动作，由于配置了eslint-plugin-prettier，让prettier成为了eslint的rule，这样便使得保存代码的时候，代码不仅按照eslint自动修复了，同时也按照prettier自动修复了

  {
    "editor.codeActionsOnSave": {
        "source.fixAll.eslint": true,
        "source.fixAll.stylelint": true
    },
    "eslint.validate": [
        "javascript",
        "javascriptreact",
        "typescript",
        "typescriptreact",
        "json"
    ]
  }

IDE(vscode)配置

• 扩展程序中添加 ESLint, Prettier - Code formatter, Stylelint(暂时可不加), EditorConfig for VS Code

• 配置settings.json(工作区)

  通过此配置，代码保存的时候自动执行eslint的修复动作，由于配置了eslint-plugin-prettier，让prettier成为了eslint的rule，这样便使得保存代码的时候，代码不仅按照eslint自动修复了，同时也按照prettier自动修复了

  {
    "editor.codeActionsOnSave": {
        "source.fixAll.eslint": true,
        "source.fixAll.stylelint": true
    },
    "eslint.validate": [
        "javascript",
        "javascriptreact",
        "typescript",
        "typescriptreact",
        "json"
    ]
  }

• 添加.editorconfig，为了不同IDE行为保持一致，注意规则不要和prettier冲突，以下作为参考

  root = true
  [*]
  charset = utf-8
  indent_style = space
  indent_size = 2
  end_of_line = crlf
  insert_final_newline = true
  trim_trailing_whitespace = true
