Vue + element-ui 打包生成的js文件这么大正常吗？

Question

package.json 文件内容：

{
  "name": "wingspage",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "axios": "^0.18.0",
    "element-ui": "^2.4.11",
    "lodash": "^4.17.11",
    "vue": "^2.5.17",
    "vue-router": "^3.0.1"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^3.2.0",
    "@vue/cli-plugin-eslint": "^3.2.0",
    "@vue/cli-service": "^3.2.0",
    "babel-eslint": "^10.0.1",
    "eslint": "^5.8.0",
    "eslint-plugin-vue": "^5.0.0-0",
    "vue-template-compiler": "^2.5.17"
  }
}

npm run build打包输出：

> wingspage@0.1.0 build D:\GOPATH\src\WingsGo\page
> vue-cli-service build

页面功能逻辑很简单，引用组件也不多，由于js太大，打开页面比较慢（相比jquery的同等实现），前端不太熟，是不是我哪里配置不对？

Answer 1

正常，估计 element 全量引入了吧，配置下按需引入会小一点。

Answer 2

你这个大小是没有进行按需加载，官网快速上手里面有按需加载，可以参考配置

Answer 3

推荐CDN加载

Answer 4

vendors 700多k还可以吧。。。
以现在的网速这个体验差别应该不是特别大，追求极致体验当我没说。
除了cdn、按需，还可以试试：

1.路由懒加载。
2.页面做loading。
