javascript - 使用 VSCode 的更漂亮的 react/jsx-max-props-per-line 格式

Question

我在带有 React 的 JavaScript 项目中使用 Prettier。我所有的组件 Prop 都在 1 行中格式化:

<Icon icon="arrow-left" width={15} height={18} />

我想要这样:

<Icon
  icon="arrow-left"
  width={15}
  height={18}
/>

我添加了 "react/jsx-max-props-per-line": [1, { "when": "multiline" }]到我的 .prettierrc，但没有结果。

我也有一个 ESLint 配置，规则如下:

{
  "extends": [
    "eslint:recommended",
    "plugin:react/recommended",
    "plugin:prettier/recommended"
  ],
  "plugins": ["react", "prettier", "standard"],
  "rules": {
    "indent": [2, 2, { "SwitchCase": 1 }],
    "quotes": [2, "single"],
    "linebreak-style": [2, "unix"],
    "semi": [2, "always"],
    "no-console": [0],
    "no-loop-func": [0],
    "new-cap": [0],
    "no-trailing-spaces": [0],
    "no-param-reassign": [0],
    "func-names": [0],
    "comma-dangle": [0],
    "no-unused-expressions": [0],
    "block-scoped-var": [0],
    "react/prop-types": [0],
    "prettier/prettier": "error"
  }
}

我的 .prettier 文件配置:

  "bracketSpacing": true,
  "jsxBracketSameLine": true,
  "printWidth": 80,
  "singleQuote": true,
  "trailingComma": "all",
  "tabWidth": 2,
  "useTabs": false,
  "react/jsx-max-props-per-line": [1, { "when": "always" }]

可能有冲突？我试着移动 react/jsx-max-props-per-line根据 ESLint 规则，但也没有结果。没有变化。

谁能帮帮我？

我能够让它与以下项目一起工作:

// .eslintrc.js
module.exports = {
  extends: [
    'react-app',
    'prettier',
    'plugin:prettier/recommended',
  ],
  plugins: ['prettier'],
  rules: {
    'react/jsx-first-prop-new-line': [2, 'multiline'],
    'react/jsx-max-props-per-line': [
      2,
      { maximum: 1, when: 'multiline' },
    ],
    'react/jsx-indent-props': [2, 2],
    'react/jsx-closing-bracket-location': [
      2,
      'tag-aligned',
    ],
  },
}

// .prettierrc
{
 "semi": false,
 "singleQuote": true,
 "printWidth":80 // default
}

连同我的开发依赖项，这些依赖项基本上来自 eslint-config-react-app

"devDependencies": {
"@types/node": "^14.6.0",
"@types/react": "^16.9.46",
"@types/react-dom": "^16.9.8",
"@typescript-eslint/eslint-plugin": "^4.0.0",
"@typescript-eslint/parser": "^4.0.0",
"babel-eslint": "^10.0.0",
"eslint": "^7.5.0",
"eslint-config-prettier": "^7.2.0",
"eslint-config-react-app": "^6.0.0",
"eslint-plugin-flowtype": "^5.2.0",
"eslint-plugin-import": "^2.22.0",
"eslint-plugin-jest": "^24.0.0",
"eslint-plugin-jsx-a11y": "^6.3.1",
"eslint-plugin-prettier": "^3.3.1",
"eslint-plugin-react": "^7.20.3",
"eslint-plugin-react-hooks": "^4.0.8",
"eslint-plugin-testing-library": "^3.9.0",
"jest": "^26.6.3",
"prettier": "^2.2.1",
"typescript": "4.0.5"
},

如果行超过 printWidth: 80 个字符，仅格式化代码。

<InputField name="password" placeholder="password" label="Password" type="password" />
  
// transforms to this if line exceeds 'printWidth'

<InputField
  name="username"
  placeholder="username"
  label="Username"
  type="text" 
/>
