记录ESlint配置一次

作者: 乐宝呗 | 来源:发表于2024-02-19 15:15 被阅读0次

项目在多人合作时,代码格式化时不统一是个大问题。建议大家的编辑器配置统一,开启eslint,让代码看起来风格统一。

1. vscode编辑器安装插件

  1. Prettier - Code formatter
  2. ESlint

2. 根目录创建.vscode文件,内容如下

// .vscode/settings.json 
// 该文件会覆盖vscode编辑器中的settings.json,该文件没有的配置会使用vscode编辑器中的配置
{
  "eslint.enable": true,
  "eslint.options": {
    "extensions": [
      ".js",
      ".vue",
      ".ts",
      ".tsx"
    ]
  },
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
  },
  "eslint.validate": [
    "vue",
    "html",
    "javascript",
    "typescript",
    "javascriptreact",
    "typescriptreact"
  ],
  "vetur.format.defaultFormatter.html": "prettier"
}

3. 安装依赖包

"eslint": "^6.8.0",
"eslint-plugin-import": "^2.20.2",
"eslint-plugin-node": "^11.1.0",
"eslint-plugin-promise": "^4.2.1",
"eslint-plugin-standard": "^4.0.1",
"eslint-plugin-vue": "^6.2.2",
"@vue/cli-plugin-eslint": "^4.1.0",
"@vue/eslint-config-standard": "^5.1.2",
"babel-eslint": "^10.0.3",

4. 根目录下创建.editorconfig文件,内容如下

# http://editorconfig.org
root = true

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

[*.md]
insert_final_newline = false
trim_trailing_whitespace = false

5. 根目录下创建.eslintignore,内容如下

build/*.js
src/assets
public
dist

6. 根目录下创建eslintrc.js ,内容如下

{
  "name": "etb_home",
  "version": "1.0.0",
  "description": "招采e贷数据可视化系统",
  "author": "Pan <panfree23@gmail.com>",

7.根目录下创建.prettierrc.js文件,内容如下

module.exports = {
    // 最大长度80个字符
    printWidth: 300,
    // 使用单引号, 默认false(在jsx中配置无效, 默认都是双引号)
    singleQuote: true,
    // 行末分号, 默认true
    semi: false,
    // JSX双引号
    jsxSingleQuote: false,
    // 尽可能使用尾随逗号(包括函数参数),默认none,可选 none|es5|all
    // es5 包括es5中的数组、对象
    // all 包括函数对象等所有可选
    trailingComma: 'none',
    // 在对象文字中打印括号之间的空格。 默认true
    bracketSpacing: true,
    // 箭头函数参数括号 默认avoid 可选 avoid| always
    // avoid 能省略括号的时候就省略 例如x => x
    // always 总是有括号
    arrowParens: 'avoid',
    // 在文件顶部插入一个特殊的 @format 标记,指定文件格式需要被格式化。
    insertPragma: false,
    // 行尾换行格式
    endOfLine: 'auto',
    // html空格敏感度
    htmlWhitespaceSensitivity: 'ignore',
    // tab缩进大小,默认为2
    tabWidth: 2,
    // 使用tab缩进还是空格,默认false
    useTabs: true,
    // vue缩进脚本和样式
