本文介绍了如何在Vue项目中配置路由的缓存与过渡效果，通过设置路由的keepAlive属性来实现组件的缓存，并利用transition组件结合CSS实现页面切换的动画效果。

1, router.js配置每个路由的index值
2, router.js配置每个路由的keepAlive值

app.vue 代码

<template>
  <div id="app">
      <transition :name="transition">
          <keep-alive>
              <router-view v-if="$route.meta.keepAlive"></router-view>
          </keep-alive>
      </transition>
      <transition :name="transition">
          <router-view v-if="!$route.meta.keepAlive"></router-view>
      </transition>
  </div>
</template>
<style>
@import url("../static/css/reset.css");
@import url("../static/css/transition.css");
</style>
<script>
export default {
  name: "App",
  data() {
    return {
      transition: ""
    };
  },
  watch: {
    $route(to, from) {
      if (to.meta.index > from.meta.index) {
        this.transition = "slide-left";
      } else {
        this.transition = "slide-right";
      }
    }
  },
}
</script>

transition.css代码

.slide-right-enter-active,
.slide-right-leave-active,
.slide-left-enter-active,
.slide-left-leave-active {
  will-change: transform;
  transition: all 500ms;
  position: absolute;
  width:100%;
  height:100%;
}
.slide-right-enter {
  opacity: 0;
  transform: translate3d(-100%, 0, 0);
}
.slide-right-leave-active {
  opacity: 0;
  transform: translate3d(100%, 0, 0);
}
.slide-left-enter {
  opacity: 0;
  transform: translate3d(100%, 0, 0);
}
.slide-left-leave-active {
  opacity: 0;
  transform: translate3d(-100%, 0, 0);
}
