Vue动态组件实现异常处理方法

// 动态路由
export const asyncRouterMap: Array<RouteRecordRaw> = [
  {
    path: '/',
    name: 'index',
    meta: { title: '首页' },
    component: BasicLayout, // 引用了 BasicLayout 组件
    redirect: '/welcome',
    children: [
      {
        path: 'welcome',
        name: 'Welcome',
        meta: { title: '引导页' },
        component: () => import('@/views/welcome.Vue')
      },
      ...
    ]
  }
]

<el-tabs :model-value="copyTabName" type="card">
  <template v-for="item in tabList" :key="item.key || item.name">
    <el-tab-pane
      :name="item.key"
      :label="item.name"
      :disabled="item.disabled"

    // ...
  }
]

const state = shallowRef({ count: 1 })
// 不会触发更改
state.value.count = 2
// 会触发更改
state.value = { count: 2 }

const foo = markRaw({})
console.log(isReactive(reactive(foo))) // false
// 也适用于嵌套在其他响应性对象
const bar = reactive({ foo })
console.log(isReactive(bar.foo)) // false
