JavaScript 代码风格

eslint

{
  "eslint": "^5.16.0",
  "eslint-config-standard": "^6.2.1",
  "eslint-friendly-formatter": "^2.0.7",
  "eslint-loader": "^2.1.2",
  "eslint-plugin-html": "^2.0.1",
  "eslint-plugin-promise": "^3.5.0",
  "eslint-plugin-standard": "^2.3.1",
  "eslint-plugin-vue": "^5.0.0"
}

使用两个插件

• plugin:vue/essential
• standard

vue/essential 为了在 vue 里面也可以生效。 standard 是代码规范 细则 (opens new window)

prettier

开启 vscode 自动格式化

{
  // prettier
  "prettier.singleQuote": true,
  "prettier.semi": false,
  "prettier.tabWidth": 2,
  "[javascript]": {
    "editor.formatOnSave": true,
    "editor.defaultFormatter": "esbenp.prettier-vscode"
  }
}
