Usage of Vue Router

 The main feature of SPA single page is that a layer of front-end routing is added on the basis of the separation of front-end and back-end. That is, the front end maintains a set of routing rules. The user clicks the routing link on the page, which causes the Hash value in the URL address bar to change. The front-end routing monitors the change of the Hash address, and the front-end routing renders the component corresponding to the current Hash address to the browser. Vue-router is the routing solution officially given by Vue. It can only be used in conjunction with the vue project, and can easily manage the switching of components in the SPA project. For VueRouter, routing is the decision-making process of selecting a component for rendering based on a request path.

Install vue-router: nmp i vue-router

Write configuration items

import VueRoute from "vue-router"
import A from "../components/A.vue"
import B from "../components/B.vue"

export default new VueRoute({
    routes:[
        {
            path:"/a",
            component:A
        },
        {
            path:"/b",
            component:B
        }
    ]
})

Introduce registration

import Vue from 'vue';
import App from './App.vue';
//
import VueRouter from "vue-router"
import router from "./router/index.js"
Vue.config.productionTip = false;
Vue.use(VueRouter)
const vm=new Vue({
  render: h => h(App),
  router,
}).$mount('#app');

Specify placements

 <router-link></router-link>
<router-view></router-view>

ES6 arrow functions

 In ES6, in addition to the new features of let and const, arrow functions are the most frequently used new features. But this feature is not unique to ES6. Arrow functions, as the name suggests, are functions defined using arrows (=>) and belong to a class of anonymous functions. It allows us to write smaller function syntaxes. The code of arrow functions is simpler and more flexible to write.

Three external exposure methods and introduction methods of export in ES6

 In the JS era a few years ago, there was no concept of modularity. However, as front-end projects become larger and more complex, it is urgent to introduce the concept of modularity. Before ES6, the community developed some modular solutions, such as: CommonJS and AMD and CMD. These are slowly being replaced by import and export after ES6. Export is used to specify the interface that the module opens to the outside world. Regardless of whether you define it or not, the module exported by export is in strict mode and cannot be used in embedded scripts. The import command is used to import functionality provided by other modules.
