How to configure and use CDN acceleration in Vue

With the increasing development of front-end development, the loading speed of web pages has become one of the important indicators of user experience. The emergence of CDN (Content Delivery Network) acceleration technology provides us with a solution to speed up web page loading. This article will introduce how to configure and use CDN acceleration in Vue, and provide specific code examples.

1. Introduction to CDN
CDN is a distributed system that distributes resources to the server closest to the user through multiple servers distributed in different geographical locations, reducing loading time and delay. The commonly used Vue family buckets (Vue.js, Vue Router and Vuex) already have official CDN accelerated versions. These CDN links can be introduced into the project to speed up resource loading.

2. Configure CDN acceleration

1. In the index.html file, find the tag and add the following code:

<!-- 引入Vue.js CDN -->
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<!-- 引入Vue Router CDN -->
<script src="https://cdn.jsdelivr.net/npm/vue-router"></script>
<!-- 引入Vuex CDN -->
<script src="https://cdn.jsdelivr.net/npm/vuex"></script>

In this way, the three libraries of Vue.js, Vue Router and Vuex are introduced into the project.

2. In the configuration file vue.config.js of the Vue project, add the following code:

module.exports = {
  // 配置CDN
  configureWebpack: {
    externals: {
      // vue: "Vue",
      // "vue-router": "VueRouter",
      // vuex: "Vuex"
      // 如果使用上面注释的代码，CDN引入的包将会挂载在全局变量Vue上
      // 如果不想挂载在Vue上，还可以通过以下方式引入
      vue: {
        commonjs: "vue",
        commonjs2: "vue",
        amd: "vue",
        root: "Vue"
      },
      "vue-router": {
        commonjs: "vue-router",
        commonjs2: "vue-router",
        amd: "vue-router",
        root: "VueRouter"
      },
      vuex: {
        commonjs: "vuex",
        commonjs2: "vuex",
        amd: "vuex",
        root: "Vuex"
      }
    }
  }
};

This will configure the CDN acceleration, which actually tells webpack, These imported libraries are already on the CDN and do not need to be packaged into the project.

3. Use CDN to accelerate

1. Use Vue Router and Vuex in the component:

import Vue from "vue";
import VueRouter from "vue-router";
import Vuex from "vuex";

Vue.use(VueRouter);
Vue.use(Vuex);

const router = new VueRouter({
  routes: [...]
});

const store = new Vuex.Store({
  // ...
});

2. In the entry file main.js, Create a Vue instance and mount it on the DOM:

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount("#app");

In this way, you can use Vue Router and Vuex normally. They have been introduced into the project through CDN acceleration.

Summary
CDN acceleration is a method of optimizing web page loading speed by distributing resources to the server closest to the user, reducing loading time and latency. Using CDN acceleration in Vue is very simple. You just need to introduce CDN links into the project and tell webpack in the configuration file that these libraries are already on CDN. This article provides specific code examples, hoping to be helpful to Vue developers.
