package.json里配置添加
1.scripts里添加快捷eslint检查命令
"lint": "eslint --ext .js,.vue src"
2.添加eslint依赖包
"babel-eslint": "^8.2.1", "eslint": "^4.15.0", "eslint-config-standard": "^10.2.1", "eslint-friendly-formatter": "^3.0.0", "eslint-loader": "^1.7.1", "eslint-plugin-import": "^2.7.0", "eslint-plugin-node": "^5.2.0", "eslint-plugin-promise": "^3.4.0", "eslint-plugin-standard": "^3.0.1", "eslint-plugin-vue": "^4.0.0",
根目录下添加检测配置js文件.eslintrc.js
// https://eslint.org/docs/user-guide/configuring
module.exports = {
root: true,
parserOptions: {
parser: 'babel-eslint'
},
env: {
browser: true,
},
extends: [
// https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
// consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
'plugin:vue/essential',
// https://github.com/standard/standard/blob/master/docs/RULES-en.md
'standard'
],
// required to lint *.vue files
plugins: [
'vue'
],
// add your custom rules here
rules: {
// allow async-await
'generator-star-spacing': 'off',
// allow debugger during development
'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off'
}
}添加忽略检测配置文件.eslintignore
/build/
/config/
/dist/
/*.js
webpack.base.conf.js rules里添加eslint-loader配置
const createLintingRule = () => ({
test: /\.(js|vue)$/,
loader: 'eslint-loader',
enforce: 'pre',
include: [resolve('src'), resolve('test')],
options: {
formatter: require('eslint-friendly-formatter'),
emitWarning: !config.dev.showEslintErrorsInOverlay
}
})
module.exports = {
//.......
module: {
rules: [
...(config.dev.useEslint ? [createLintingRule()] : []),
//.....config->index.js的dev里添加
useEslint: true, showEslintErrorsInOverlay: false,
Eslint的一些规则说明
1.使用Eslint的时候如果出现未闭合标签会报红
如下：
对于有强迫症的我来说不能无视，怎么搞定？
首先找到 .eslintrc.js文件
在 rules 添加以下规则
"vue/html-self-closing": ["error",{
"html": {
"void": "never",
"normal": "any",
"component": "any"
},
"svg": "always",
"math": "always"
}],保存即可
2.需要在单行元素的内容之前和之后换行
规则：
"vue/singleline-html-element-content-newline": false,
以上为个人经验，希望能给大家一个参考，也希望大家多多支持Devmax。
