How to use routing to customize the page switching animation effect in the Vue project?

Introduction:
In the Vue project, routing is one of the functions we often use. Switching between pages can be achieved through routing, providing a good user experience. In order to make page switching more vivid, we can achieve it by customizing animation effects. This article will introduce how to use routing to customize the page switching animation effect in the Vue project.

1. Create Vue project
   First, we need to create a Vue project. You can use Vue CLI to quickly build a basic Vue project. The command is as follows:

   vue create project-name

2. Install Vue Router
   Install Vue Router in the project, you can install it through the following command:

   npm install vue-router

3. Customized page switching animation effect
   In the Vue project, page switching can be achieved through the <transition></transition> component provided by Vue Router animation effects. We can achieve customized page switching animation effects by wrapping a <transition></transition> component outside the <router-view></router-view> component and setting the class name of the animation effect. The specific steps are as follows:

• Introduce Vue Router and create a routing instance in the project’s entry file main.js:

  import VueRouter from 'vue-router'
  import App from './App.vue'
  
  Vue.use(VueRouter)
  
  const router = new VueRouter({
  routes: [
    // 配置路由规则
  ]
  })
  
  new Vue({
  router,
  render: h => h(App),
  }).$mount('#app')

• Use <router-view></router-view> in the root component of the project App.vue to display the components corresponding to the current route:

  <template>
  <div id="app">
    <transition name="fade" mode="out-in">
      <router-view></router-view>
    </transition>
  </div>
  </template>

• Define the fade animation effect in the style file of App.vue:

  .fade-enter-active, .fade-leave-active {
  transition: opacity 0.5s;
  }
  
  .fade-enter, .fade-leave-to {
  opacity: 0;
  }

In this way, when the route switches, the page The transition animation of the fade effect will be displayed.

4. Customize different page switching animation effects
   If you need to customize different switching animation effects for different pages, you can set the meta field in the routing configuration, in the component Read this field in to dynamically set the class value of the animation effect. The specific steps are as follows:

• Set the meta field in the routing configuration:

  const router = new VueRouter({
  routes: [
    { 
      path: '/page1', 
      component: Page1, 
      meta: { transition: 'slide' } 
    },
    { 
      path: '/page2', 
      component: Page2, 
      meta: { transition: 'fade' } 
    },
  ]
  })

• at In App.vue, set the class name of the animation effect according to the meta field of the route:

  <template>
  <div id="app">
    <transition :name="transitionName" mode="out-in">
      <router-view></router-view>
    </transition>
  </div>
  </template>
  
  <script>
  export default {
  data() {
    return {
      transitionName: 'fade'  // 默认动画效果
    }
  },
  watch: {
    $route(to, from) {
      // 根据路由的meta字段设置动画效果的class名
      this.transitionName = to.meta.transition || 'fade';  
    }
  }
  }
  </script>

In this way, every time the route is switched, it will be based on the route The meta field is used to dynamically set the animation effect of page switching.
