1. 路由模式-将路由改成history模式
- hash模式带#,#后面的地址变化不会引起页面的刷新
- history没有#,地址变化会引起页面刷新,更符合页面地址的规范(开发环境不刷新-webpack配置)
- 将路由模式修改成history模式-代码位置(src/router/index.js)
const createRouter = () => new Router({
mode: 'history', // require service support
scrollBehavior: () => ({ y: 0 }),
routes: constantRoutes // 默认引入静态路由
})
2. 打包分析-分析
- 打包分析代码
$ npm run preview -- --report
- 去除main.js中对于mock.js的引用
3. CDN加速
将几个比较大的多在打包时排除,这样可以缩小整体打包的大小,保证js的加载速度,排除的包采用cdn的方式用外链去引入,cdn本名为分发服务器,意为更近的访问区间更快的访问速度将所需要的文件返回给客户端
- webpack排除打包-代码位置(vue.config.js)
configureWebpack: {
// provide the app's title in webpack's name field, so that
// it can be accessed in index.html to inject the correct title.
name: name,
resolve: {
alias: {
'@': resolve('src')
}
},
// 配置需要排出的包
externals: {
'vue': 'Vue',
'element-ui': 'ELEMENT',
'cos-js-sdk-v5': 'COS'
}
},
- 在html中采用外链引入排除的文件-代码位置(public/index.html)
