Vue3KeepAlive

✨ 务必安装 vue-router 依赖

快速配置

修改 App.vue 👇

<template>
  <RouterView v-slot="routerViewSlot">
    <KeepAlive :include="getKeepInclude">
      <component :is="setKeepName(routerViewSlot)" />
    </KeepAlive>
  </RouterView>
</template>

<script lang="ts" setup>
import { keepInit } from 'Vue3KeepAlive'

const { getKeepInclude, setKeepName } = keepInit()
</script>

使用方法

为页面 routes.meta 添加 keepAlive 参数即可 e.g. 👇

• 常规路由

...

const router = VueRouter.createRouter({
  history: VueRouter.createWebHashHistory(),
  routes: [
    ...
    {
      path: '/',
      component: Home,
      meta: {
        title: 'home',
        keepAlive: true // 页面开启缓存
      },
    },
    {
      path: '/about',
      component: About,
      meta: {
        title: 'about',
        keepAlive: {
          include: ['/abc'], // 仅当从 '/abc' 页面跳转到当前页时, 当前页具有缓存
        },
      },
    },
    ...
  ]
});

...

• 约定式路由

<script lang="ts" setup>
definePage({
  meta: {
    title: 'home',
    keepAlive: {
      include: ['/abc'], // 仅当从 '/abc' 页面跳转到当前页时, 当前页具有缓存
    },
  },
})
</script>
