Tips for ensuring the "keep-alive" functionality of a component stays active when using router-view in Vue 3

I have successfully developed a small application with two main components using vue router for navigation.

The first component is named MoviesList and the second one is Movie. I have defined them in the routes.js file.

const routes = [
  {
    path: '/',
    name: 'Home',
    component: MoviesList
  },

  {
    path: '/:movieId',
    name: 'Movie',
    component: Movie
  }
  
]

Here's how my App.vue template looks like:

<template>
   <router-view></router-view>
</template>

Is there a way to cache the MoviesList component as if it was wrapped with <keep-alive> tags? I want the MoviesList component to be cached while keeping the Movie component unaffected.

This is needed because the MoviesList component has a method that executes on the mounted() hook, but when I navigate away and come back, the method runs again due to re-rendering of the component.

Answer №1

give this a shot include="MoviesList", or you can also try exclude="Movie"

<router-view v-slot="{ Component }">
  <keep-alive include="MoviesList">
    <component :is="Component" />
  </keep-alive>
</router-view>

Answer №2

Utilize the keep-alive component within the router-view and display it conditionally based on the current component:

<router-view v-slot="{ Component }">
 <template v-if="Component.name==='movie-list'">
    <keep-alive>
      <component :is="Component" />
    </keep-alive>
 </template>
<template v-else>
     <component :is="Component" />
</template>

</router-view>

Answer №3

I found this example for Vue.js 2.0 to be extremely helpful!

The important thing to note is that you need to use the component name in the include section:

<keep-alive include="componentname">
  <router-view></router-view>
</keep-alive>
const MyComponent = {
  name: 'componentname',
  template: '<div>My awesome component!</div>'
}

const routes = [
  {
    path: '',
    component: MyComponent
  }
]
