CSDN话题挑战赛第2期
参赛话题:学习笔记
1、package.json配置中的重点介绍:
1、许可证:license:各种License介绍(BSD,MIT,MPL,Apache License,CC)_赵健乔的博客-CSDN博客
2、脚本别名:scripts:
对命令的一种别名设定,方便使用的
3、一种第三方的检测书写规范的插件:git hooks工具:husky
"husky": {
"hooks": {
"pre-commit": "lint-staged"
}
},
"lint-staged": {
"src/**/*.{js,vue}": [
"eslint --fix",
"git add"
]
},
4、需要发布的依赖插件管理:dependencies
"dependencies": {
"@riophae/vue-treeselect": "0.4.0",
"axios": "0.24.0",
"clipboard": "2.0.8",
"core-js": "3.19.1",
"echarts": "4.9.0",
"element-ui": "2.15.8",
"file-saver": "2.0.5",
"fuse.js": "6.4.3",
"highlight.js": "9.18.5",
"js-beautify": "1.13.0",
"js-cookie": "3.0.1",
"jsencrypt": "3.0.0-rc.1",
"nprogress": "0.2.0",
"quill": "1.3.7",
"screenfull": "5.0.2",
"sortablejs": "1.10.2",
"vue": "2.6.12",
"vue-count-to": "1.0.13",
"vue-cropper": "0.5.5",
"vue-meta": "2.4.0",
"vue-router": "3.4.9",
"vuedraggable": "2.24.3",
"vuex": "3.6.0"
},
5、只需要在本地开发过程使用的依赖插件的管理:devDependencies
"devDependencies": {
"@vue/cli-plugin-babel": "4.4.6",
"@vue/cli-plugin-eslint": "4.4.6",
"@vue/cli-service": "4.4.6",
"babel-eslint": "10.1.0",
"babel-plugin-dynamic-import-node": "2.3.3",
"chalk": "4.1.0",
"compression-webpack-plugin": "5.0.2",
"connect": "3.6.6",
"eslint": "7.15.0",
"eslint-plugin-vue": "7.2.0",
"lint-staged": "10.5.3",
"runjs": "4.4.2",
"sass": "1.32.13",
"sass-loader": "10.1.1",
"script-ext-html-webpack-plugin": "2.1.5",
"svg-sprite-loader": "5.1.1",
"vue-template-compiler": "2.6.12"
},
6、指定node和npm版本的:engines
"engines": {
"node": ">=8.9",
"npm": ">= 3.0.0"
},
7、 检测浏览器的兼容性插件:browserslist
"browserslist": [
"> 1%", //需要兼容全球使用人数超过百分之1的主流浏览器
"last 2 versions" //需要兼容最新的两个版本
]
2、vue.config.js 配置文件详解:
官方文档:配置参考 | Vue CLI
所用配置的注解都写在代码后面了,个人觉得开发过程中应该也用不太到更改:
'use strict'
const path = require('path') //node提供的通用模块
function resolve(dir) {
return path.join(__dirname, dir)
}
const CompressionPlugin = require('compression-webpack-plugin')
const name = process.env.VUE_APP_TITLE || '若依管理系统' // 网页标题
const port = process.env.port || process.env.npm_config_port || 80 // 默认启动的端口
// vue.config.js 配置说明
//官方vue.config.js 参考文档 https://cli.vuejs.org/zh/config/#css-loaderoptions
// 这里只列一部分,具体配置参考文档
module.exports = {
// 部署生产环境和开发环境下的URL(路径)。
// 默认情况下,Vue CLI 会假设你的应用是被部署在一个域名的根路径上
// 例如 https://www.ruoyi.vip/。如果应用被部署在一个子路径上,你就需要用这个选项指定这个子路径。例如,如果你的应用被部署在 https://www.ruoyi.vip/admin/,则设置 baseUrl 为 /admin/。
publicPath: process.env.NODE_ENV === "production" ? "/" : "/",
// 在npm run build 或 yarn build 时 ,生成文件的目录名称(要和baseUrl的生产环境路径一致)(默认dist)
outputDir: 'dist',
// 用于放置生成的静态资源 (js、css、img、fonts) 的;(项目打包之后,静态资源会放在这个文件夹下)
assetsDir: 'static',
// 是否开启eslint代码保存检测,有效值:ture | false | 'error'
lintOnSave: process.env.NODE_ENV === 'development',
// 如果你不需要生产环境的 source map,可以将其设置为 false 以加速生产环境构建,一般都设置为false
productionSourceMap: false,
// webpack-dev-server 相关配置
devServer: {
host: '0.0.0.0',
port: port,
open: true,
proxy: {//代理相关配置
// detail: https://cli.vuejs.org/config/#devserver-proxy
[process.env.VUE_APP_BASE_API]: { // 匹配条件
target: `http://localhost:8080`, //请求默认路径
changeOrigin: true,
pathRewrite: {
['^' + process.env.VUE_APP_BASE_API]: '' //重写地址(可以加很多个)
}
}
},
disableHostCheck: true
},
css: {
loaderOptions: {
sass: {
sassOptions: { outputStyle: "expanded" }
}
}
},
configureWebpack: {
name: name,
resolve: {
alias: {
'@': resolve('src') //用处就是 用@代表 /src
}
},
plugins: [
// http://doc.ruoyi.vip/ruoyi-vue/other/faq.html#使用gzip解压缩静态文件
new CompressionPlugin({
cache: false, // 不启用文件缓存
test: /\.(js|css|html)?$/i, // 压缩文件格式
filename: '[path].gz[query]', // 压缩后的文件名
algorithm: 'gzip', // 使用gzip压缩
minRatio: 0.8 // 压缩率小于1才会压缩
})
],
},
chainWebpack(config) {
config.plugins.delete('preload') // 删除预加载标签,减轻服务器压力
config.plugins.delete('prefetch') // 删除预加载标签,减轻服务器压力
// set svg-sprite-loader
//模块化压缩打包规则配置
config.module
.rule('svg')
.exclude.add(resolve('src/assets/icons'))
.end()
config.module
.rule('icons')
.test(/\.svg$/) //检测配置,告诉系统遇到svg文件就用下面配置的svg-sprite-loader处理
.include.add(resolve('src/assets/icons'))
.end()
.use('svg-sprite-loader')
.loader('svg-sprite-loader')
.options({
symbolId: 'icon-[name]'
})
.end()
config
.when(process.env.NODE_ENV !== 'development',
config => {
config
.plugin('ScriptExtHtmlWebpackPlugin') // webpack工具下预加载的插件
.after('html')
.use('script-ext-html-webpack-plugin', [{
// `runtime` must same as runtimeChunk name. default is `runtime`
inline: /runtime\..*\.js$/
}])
.end()
config
.optimization.splitChunks({
chunks: 'all',
cacheGroups: {
libs: {
name: 'chunk-libs',
test: /[\\/]node_modules[\\/]/,
priority: 10,
chunks: 'initial' // only package third parties that are initially dependent
},
elementUI: {
name: 'chunk-elementUI', // split elementUI into a single package
priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
},
commons: {
name: 'chunk-commons',
test: resolve('src/components'), // can customize your rules
minChunks: 3, // minimum common number
priority: 5,
reuseExistingChunk: true
}
}
})
config.optimization.runtimeChunk('single'),
{
from: path.resolve(__dirname, './public/robots.txt'), //防爬虫文件
to: './' //到根目录下
}
}
)
}
}
3、main.js 配置文件详解:
先记录一下import里涉及到的不同:
1)为什么有的用from有的不用from?
因为涉及到组件的二次加工使用就需要用from,如果是单纯的使用就可以直接用import全部引入,比如css文件一般就是需要全部引入的
2)路径使用中@ / ./ ../ 之间有什么不同?
@在前面的配置文件中配置过,就是/src 的平替
/ 就是代表根目录
./ 就是代表同级目录下的文件
../ 就是代表上一级目录下的文件
