🔥 Vue Tip: Cache Component Instances With the KeepAlive Component
KeepAliveKeepAlive is a built-in Vue component that allows you to conditionally cache component instances when dynamically switching between multiple components.
Let's take a look at a simple example to understand how KeepAliveKeepAlive works. We have two components, ComponentAComponentA and ComponentBComponentB, and we want to cache the instances of these components when switching between them.
1<script setup>2import { shallowRef } from 'vue';3import ComponentA from './components/ComponentA.vue';4import ComponentB from './components/ComponentB.vue';56const current = shallowRef(ComponentA);7</script>89<template>10 <div>11 <label12 ><input type="radio" v-model="current" :value="ComponentA" /> A</label13 >14 <label15 ><input type="radio" v-model="current" :value="ComponentB" /> B</label16 >17 </div>18 <component :is="current"></component>19</template>
If you switch between the components using the radio buttons, you will notice that the component instances are destroyed and recreated every time you switch between them. Thus, the state of each component is lost.
If you want to cache the instances of the components, you can wrap the componentscomponents element with the KeepAliveKeepAlive component.

Saturday, April 5, 2025 I finally looked at my nest egg and was shocked to see the new number. Even worse that the dollars in the account will buy even less as the US dollar loses its value as the flight to safety currency. It's not a big surprise as the US behaves like a drunk Dunning-Kruger deluded schoolyard bully. What is amazing, if you think about it, is that we aren't having an emergency impeachment and trial to get him out of there. That could actually restore a bit of confidence of the outside world, showing that the power in the US is more with the people than it has been for a long time. Maybe our would-be overlords are scared too at what their idea has unleashed. Even if Trump weren't so inept, eventually whoever you choose as the monarch, they're going to behave like this. Inevitable. We could have a revolution right now, fix this, and set the country on the right course. We could do it. I believe we could. # And btw it could be worse ....
