vue-cli4项目开启eslint vue-cli4项目开启eslint保存时自动格式问题
c347087870 人气:0最近新建一个vue-cli4的项目,初始化的时候没开启eslint,后面想开启的时候不好配置,这里就做个开启eslint和保存时自动修复格式的总结
vscode首先安装eslint插件
配置vscode的自动保存eslint格式
Ctrl+shift+p
把下面代码复制到里面
"editor.tabSize": 2, "eslint.alwaysShowStatus": true, "eslint.autoFixOnSave": true, "eslint.packageManager": "yarn", "eslint.validate": [ "javascript", // 用eslint的规则检测js文件 { "language": "js", "autoFix": true }, { "language": "vue", "autoFix": true }, ], "eslint.options": { "extensions": [ ".js", ".vue" ] }, "editor.codeActionsOnSave": { "source.fixAll.eslint": true }, "eslint.run": "onSave", "files.autoSaveDelay": 3000, "eslint.codeAction.disableRuleComment": { }, "files.autoSave": "off",
项目中安装eslint
在package.json
文件中的devDependencies
里面添加
"@vue/cli-plugin-eslint": "~4.4.0", "babel-eslint": "^10.1.0", "eslint": "^6.7.2", "eslint-plugin-vue": "^6.2.2",
vue.config.js
文件里面lintOnSave
改成"warning"
根目录添加eslint配置文件
.eslintrc.js
内容根据需要修改
module.exports = { "root": true, "env": { "node": true }, "extends": [ "plugin:vue/recommended", "eslint:recommended" ], "rules": { "indent": ["error", 2], "dot-location": [ 2, "property" ], "comma-spacing": [1], "space-before-blocks": [ 2, "always" ], // 强制在块之前使用一致的空格 "space-unary-ops": [ 2, { "words": true, "nonwords": false } ], // 强制在一元操作符前后使用一致的空格 "array-bracket-spacing": [ 2, "never" ], // 强制数组方括号中使用一致的空格 "quotes": [ 0, "double" ], // 强制使用一致的反勾号、双引号或单引号 "arrow-spacing": [ 2, { "before": true, "after": true } ], "vue/max-attributes-per-line":0, "no-var": 2, //禁用var,用let和const代替 "no-mixed-spaces-and-tabs": 2, // 禁止空格和 tab 的混合缩进 "no-trailing-spaces": 1, // 禁用行尾空格 "no-unexpected-multiline": 2, // 禁止出现令人困惑的多行表达式 "no-unused-vars": [ 2, { "vars": "all", "args": "none" } ], // 禁止出现未使用过的变量 "vue/html-indent": [ 0, "tab" ], "vue/html-self-closing": [0], "vue/multiline-html-element-content-newline": [0], "vue/singleline-html-element-content-newline":[0], "vue/html-closing-bracket-newline":[0], "vue/no-v-html": [0] }, "parserOptions": { "parser": "babel-eslint" } }
