🔥 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.

Read this on my blog Hey all! Tomorrow I'm launching Composable Design Patterns — a collection of 15 patterns on how to use the composition API better.

You'll be getting a special launch discount, so make sure to pay attention to your email inbox tomorrow. Other than that, I've got a new podcast episode for you, and some links to check out, as well as some tips. Enjoy your week! — Michael ...
Hey! I need to clear some things up. You might be interested in learning how to write better composables, but unsure if Composable Design Patterns is right for you. If you're a beginner Vue dev, this is perfect to get you started off on the right foot — without developing bad habits or learning things the hard way. And if you've been writing Vue for a while, you'll get immediate value from this course because you'll be able to see exactly how these patterns will help you. You've experienced the pain of badly written composables (maybe even ones you wrote yourself 🙃). For those of you who are transitioning from the Options API to the Composition API (which is better for many reasons ), I specifically included the Options to Composition pattern to provide a super simple path for upgrading your app one component at a time. But this course isn't for everyone. This course is designed for professional Vue developers . If you're a student, o...
