vue-cli常用设置总结
时间：2021-01-14 11:13:26|栏目：vue|点击： 次
基于vue-cli做了好几个项目了，想把一些自己的常用设置写出来，磨了好久，一看vue-cli3.0都快出来了，不能再磨了。。
路径相关
css内引用的资源
build -> utils.js
// generate loader string to be used with extract text plugin
function generateLoaders (loader, loaderOptions) {
//less
// Extract CSS when that option is specified
// (which is the case during production build)
if (options.extract) {
return ExtractTextPlugin.extract({
use: loaders,
publicPath: '../../', //注意: 此处根据路径, 自动更改
fallback: 'vue-style-loader'
})
} else {
return ['vue-style-loader'].concat(loaders)
}
}
本地访问
config -> index.js
module.exports = {
build: {
//less
//assetsPublicPath: '/',
assetsPublicPath: './',
//less
},
//less
}
调试相关
内网访问
config -> index.js
module.exports = {
//less
dev: {
//less
port: process.env.PORT || 8080,//可改端口
host:'192.168.0.105',//不是8080端口可能需要指定host为本机IP
}
}
跨域代理
config -> index.js
module.exports = {
//less
dev: {
//less
proxyTable: {
'/AppHome': {
target: 'http://192.168.0.211:2334',//接口域名
changeOrigin: true,//是否跨域
pathRewrite: {
'^/AppHome': '/AppHome'//需要rewrite重写
}
}
},
}
}
config -> dev.env.js
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
API_HOST: '"AppHome/"'
})
config -> prod.env.js
module.exports = {
NODE_ENV: '"production"',
API_HOST: '"http://xxx.xxx.com/AppHome/"' //生产环境改为绝对地址，免得路径错了
}
//调用
this.$http
.post(process.env.API_HOST + "GetApproveTypeList", { ID: 0 })
.then(data => {
let $data = data.data;
if ($data.IsSuccess) {
this.list.push(...$data.Model);
}
});
路由加载切换
异步加载可以加快首屏加载速度，但是在开发阶段会导致热加载变慢，所以根据NODE_ENV来判断，开发环境不使用异步
let _import
if (process.env.NODE_ENV === 'development') {
_import = file => require('@/components/' + file + '.vue').default
}
if (process.env.NODE_ENV === 'production') {
_import = file => () => import('@/components/' + file + '.vue')
}
routes: [
{
path: '/',
name: 'Index',
component: _import('Approve/Index'),
meta: {
level: 1
}
},
]
打包
dll打包
1、在build目录新建webpack.dll.conf.js
var path = require("path");
var webpack = require("webpack");
module.exports = {
// 你想要打包的模块的数组
entry: {
vendor: ['vue/dist/vue.esm.js', //有些资源需要直接指定js，否则会重复打包
'vuex',
'axios',
'vue-router'
]
},
output: {
path: path.join(__dirname, '../static/js'), // 打包后文件输出的位置
filename: '[name].dll.js',
library: '[name]_library'
// vendor.dll.js中暴露出的全局变量名。
},
plugins: [
new webpack.DllPlugin({
path: path.join(__dirname, '..', '[name]-manifest.json'),
name: '[name]_library',
context: __dirname
}),
// 压缩打包的文件
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
})
]
};
2、在build目录下的webpack.prod.conf.js添加新插件
const webpackConfig = merge(baseWebpackConfig, {
//less
plugins: [
//less
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('../vendor-manifest.json')
})
]
})
3、在项目根目录下的index.html内添加dll.js引用
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>title</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <body> <div id="app"></div> <!-- built files will be auto injected --> <script src="./static/js/vendor.dll.js"></script> </body> </html>
4、在项目根目录下的package.json内添加dll命令(顺便给build命令添加report)，运行一次生成dll.js
"scripts": {
"dev": "node build/dev-server.js",
"start": "npm run dev",
"build": "node build/build.js --report",
"dll": "webpack --config build//webpack.dll.conf.js"
}
关闭SourceMap
config -> index.js
module.exports = {
//less
build: {
//less
productionSourceMap: false,
},
}
