Why do you need this plugin

The built-in keep-alive component is very useful in development, but it is not intelligent enough, it is difficult to clean up the page cache later, you need to use exclude and include API to save memory, and it cannot be accurately destroyed for different pages created by the same component.

If you have experienced mobile native development, you will not be troubled by this problem, because the model similar to NavigationController to manage each page is a stack structure, and the top page of the stack is destroyed when returning back.(The API is push and pop )

Features

  1. Automatically detect forward or backward
  2. Automatically destroy the current page cache when routing back
  3. Automatically create a new cache instance when routing forward, regardless of whether the component is cached or not
  4. After refreshing the page, it is still able to accurately identify forward or backward
  5. replaceStay whitelist helps cache pages when tab switching
  6. singleton allows you to set a globally unique page instance
  7. sk-transition allows you to use two animations to simulate the native stacking effect

Usage

  1. npm i -s stack-keep-alive | yarn add stack-keep-alive
  2. Replace the keep-alive component with stack-keep-alive (no need to import, registered global component)
<router-view v-slot="{ Component }">
  <stack-keep-alive v-slot='{ key }'> 
      <component :is="Component" :key='key'/>
  </stack-keep-alive>
</router-view>
  1. When the app is initialized, use the StackKeepAlive plugin
import StackKeepAlive from 'stack-keep-alive'
const app = Vue.createApp({})
app.use(StackKeepAlive)
...

Configuration

1. replace whitelist

When the tab bar is switched, some tab pages need to be retained, and these paths can be configured in replaceStay

<stack-keep-alive v-slot='{ key }' :replaceStay='["/foo"]'> 
    <component :is="Component" :key='key'/>
</stack-keep-alive>

2. transition

For use with transition, you need to replace the transition component with the built-in sk-transition component.Use name and back_name to achieve two different animation effects. Sameple Code here

    <router-view v-slot="{ Component }">
      <sk-transition name='slide-left' back_name='slide-right'>
        <stack-keep-alive v-slot="{ key }">
          <component :is="Component" :key='key'/>
        </stack-keep-alive>
      </sk-transition>
    </router-view>

3. singleton route

Sometimes it is expected that a component is only created once in the entire application life cycle, such as the common shopping cart page, in this case, use singleton to configure singleton route

<stack-keep-alive v-slot='{ key }' :singleton='["/foo"]'> 
    <component :is="Component" :key='key'/>
</stack-keep-alive>
