Using routing in Vue

Introduction to Vue routing mechanism

## Routing in #Vue.js is a built-in feature for managing page navigation in a Single Page Application (SPA). It allows developers to create and manage different URL paths that correspond to different components or views of the application.

How to use Vue routing

1. Install the Vue routing library

npm install vue-router@next

2. Create a router instance

Create a new Vue Router instance in the Vue.js application.

import VueRouter from 'vue-router'
import Home from './components/Home.vue'
import About from './components/About.vue'

const router = new VueRouter({
  routes: [
    { path: '/', component: Home },
    { path: '/about', component: About }
  ]
})

3. Install the router instance into the Vue instance

Install the router instance into the Vue.js instance.

new Vue({
  router,
  el: '#app'
})

4. Define the routing link

Use the

tag in the component to define the routing link.

<router-link to="/about">关于我们</router-link>

5. Display routing view

Use the

tag in the root component to display the currently activated routing component.

<router-view></router-view>

Advanced usage

Dynamic routing

Use a colon (:) to define a dynamic routing segment and then use it in the component

$route.params Access them.

const router = new VueRouter({
  routes: [
    { path: '/user/:id', component: User }
  ]
})

Nested Routing

Nest child routes within parent routes to create more complex hierarchical navigation.

const router = new VueRouter({
  routes: [
    {
      path: '/admin',
      component: Admin,
      children: [
        { path: 'users', component: Users },
        { path: 'products', component: Products }
      ]
    }
  ]
})

Route Guard

Use route guards to perform certain actions before or after a navigation occurs.

router.beforeEach((to, from, next) => {
  // ...
})
