如何在Vue项目中使用路由实现标签页缓存和管理？

// main.js

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const routes = [
  // 路由配置
]

const router = new VueRouter({
  routes
})

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

// 路由配置示例

import HomePage from '@/components/HomePage.vue'
import AboutPage from '@/components/AboutPage.vue'
import DetailPage from '@/components/DetailPage.vue'

const routes = [
  { path: '/', component: HomePage },
  { path: '/about', component: AboutPage },
  { path: '/detail/:id', component: DetailPage }
]

// 路由配置示例

const routes = [
  { path: '/', component: HomePage, meta: { keepAlive: true } },
  { path: '/about', component: AboutPage },
  { path: '/detail/:id', component: DetailPage }
]

// DetailPage.vue

export default {
  data() {
    return {
      cachePage: false
    }
  },
  beforeRouteLeave(to, from, next) {
    if (!this.cachePage) {
      next()
    } else {
      this.$nextTick(() => {
        // 缓存当前页面
        this.$store.commit('addCachedPage', { path: from.path, name: from.name })
        next(false)
      })
    }
  }
}

// store/index.js

export default new Vuex.Store({
  state: {
    cachedPages: []
  },
  mutations: {
    addCachedPage(state, page) {
      state.cachedPages.push(page)
    },
    removeCachedPage(state, path) {
      const index = state.cachedPages.findIndex(item => item.path === path)
      if (index !== -1) {
        state.cachedPages.splice(index, 1)
      }
    }
  },
  actions: {},
  modules: {}
})

// TabMenu.vue

export default {
  computed: {
    cachedPages() {
      return this.$store.state.cachedPages || []
    }
  }
}

<!-- TabMenu.vue -->

<template>
  <div>
    <router-link v-for="page in cachedPages" :key="page.path" :to="page.path" exact>{{ page.name }}</router-link>
  </div>
</template>
