以我现在公司的项目为例技术栈:vue.js+nuxt.js+egg.js
配置比较简单,具体步骤如下:
1、安装依赖
npm install babel-eslint eslint eslint-config-prettier eslint-loader eslint-plugin-vue eslint-plugin-prettier prettier --save-dev
2、添加配置文件 .eslintrc.js 文件:
module.exports = {
root: true,
extends: [
"eslint:recommended",
"plugin:vue/recommended",
"plugin:prettier/recommended",
],
env: {
browser: true,
node: true,
},
plugins: ["vue"],
parserOptions: {
parser: "babel-eslint",
sourceType: "module",
allowImportExportEverywhere: false,
codeFrame: false,
},
rules: {
"no-param-reassign": 0,
"max-len": [
2,
{
code: 140,
ignoreStrings: true,
ignoreTemplateLiterals: true,
ignoreRegExpLiterals: true,
ignorePattern: "data:image",
},
],
"no-plusplus": 0,
"vue/html-self-closing": 0,
"comma-dangle": 0,
"vue/require-default-prop": 0,
"no-underscore-dangle": 0,
"no-unused-expressions": 0,
"array-callback-return": 0,
"global-require": 0,
radix: 0,
"no-console": 0,
"consistent-return": 1,
"class-methods-use-this": 0,
"no-buffer-constructor": 1,
"no-continue": 0,
camelcase: 0,
"vue/attributes-order": 0,
"no-use-before-define": ["error", { functions: false, classes: false }],
"no-debugger": 0,
"vue/attribute-hyphenation": 0,
"vue/no-use-v-if-with-v-for": 0,
"no-multiple-empty-lines": 0,
strict: 0,
"lines-between-class-members": 0,
"operator-linebreak": 0,
"no-else-return": 0,
"vue/no-mutating-props": 0,
"vue/require-prop-type-constructor": 0,
"vue/return-in-computed-property": 0,
"object-curly-newline": 0,
"operator-assignment": 0,
"vue/no-unused-components": 0,
"vue/max-attributes-per-line": [
"error",
{
singleline: 3,
multiline: {
max: 3,
allowFirstLine: true,
},
},
],
},
globals: {
__NUXT__: true,
},
};
到此其实就配置完了,但还是补充几个好用的配置:
1、一个更爽的配置,可查看整个项目不符合ESLint配置的所有文件,并且可以一次性修改所有不符合ESLint配置的文件。
#在 package.json 文件中添加 checklint 和 reviselint 命令
"scripts": {
"checklint": "eslint --ext .js,.vue --ignore-path .gitignore .",
"reviselint": "eslint --fix --ext .js,.vue --ignore-path .gitignore ."
},
npm run checklint // 查看项目中的不规范
npm run reviselint // 修改项目中的不规范
2、最后如何动态的去检查代码的规范问题,这个我们只需要在配置文件 nuxt.config.js 中加入下面的配置就能在每次保存的时候在控制台或者打开项目的浏览器内看到那些代码不符合规范。
build: {
extend(config, ctx) {
// Run ESLint on save
if (ctx.isDev && ctx.isClient) {
config.module.rules.push({
enforce: "pre",
test: /\.(js|vue)$/,
loader: "eslint-loader",
exclude: /(node_modules)/
})
}
}
}
3、在VScode中,编写代码时有不规范的地方高亮显示出来并且在 Ctrl+S
保存的时候自动格式化为规范的代码,这个也是我觉得比较爽的操作,不用一个一个地方去改。
这个需要配合插件来完成 在vscode中添加eslint和vetur插件:
安装完插件以后最好重启一个VScode, 然后你就能看到项目中不符合你定义规范的代码就会高亮出来,如图:
最后也是最爽的地方,配置 Ctrl+S
保存的时候自动规范化代码

然后回到上面的文件,进入文件中,只需要 Ctrl+S
保存一下,代码自动格式化,如图:
如果你对你的代码有严格的代码洁癖或者你对你的团队有必须的代码书写规范,两者结合将会是你的代码管理起来更加方便和优雅。
还有任何东西想要熟练地使用第一点我觉得都需要认真的看一遍文档(api),这样才能让你更好的去理解他。
