vue2.0 keep-alive最佳实践

<keep-alive>
<component>
 <!-- 组件将被缓存 -->
</component>
</keep-alive>

<keep-alive><router-view></router-view></keep-alive>

// 这是目前用的比较多的方式
<keep-alive>
  <router-view v-if="!$route.meta.notKeepAlive"></router-view>
</keep-alive>
<router-view v-if="$route.meta.notKeepAlive"></router-view>

... 
 routes: [
  { path: '/', redirect: '/index', component: Index, meta: { keepAlive: true }},
  {
   path: '/common',
   component: TestParent,
   children: [
    { path: '/test2', component: Test2, meta: { keepAlive: true } } 
   ]
  }
  ....
  // 表示index和test2都使用keep-alive

<!-- comma-delimited string -->
<keep-alive include="a,b">
 <component :is="view"></component>
</keep-alive>
<!-- regex (use v-bind) -->
<keep-alive :include="/a|b/">
 <component :is="view"></component>
</keep-alive>

//其中a,b是组件的name

<keep-alive :include="includedComponents">
 <router-view></router-view>
</keep-alive>
