实现在Webstorm中,alt+f自动根据eslint规范格式化代码并在eslint中自动调用prettier规范进行格式代码

☄️ Ideas

安装eslint

npm install eslint --save-dev

执行eslint初始化命令

npx eslint --init

初始化eslint

安装eslint中prettier插件

npm install --save-dev eslint-plugin-prettier
npm install --save-dev eslint-config-prettier
npm install --save-dev --save-exact prettier

配置eslint配置文件

Note:
extends属性中prettier要排在最后，否则prettier不生效

prettier要排在最后

module.exports = {
  env: {
    browser: true,
    es2021: true,
  },
  extends: [
    'standard',
    'plugin:react/recommended',
    'prettier'
  ],
  parser: '@typescript-eslint/parser',
  parserOptions: {
    ecmaFeatures: {
      jsx: true,
    },
    ecmaVersion: 12,
    sourceType: 'module',
  },
  plugins: [
    'prettier',
    'react',
    '@typescript-eslint'
  ],
  rules: {
    'prettier/prettier': 'error',
    'no-use-before-define': 'off',
    'no-undef': 'off',
    'react/prop-types': 'off',
    'no-unused-vars': 'off',
    'node/handle-callback-err': 'off',
    'array-callback-return': 'off',
  },
};

配置prettier

Note:
修改完prettier配置文件后，需要重启webstorm才会生效

vim .prettierrc
