🔥 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.

Hey! In yesterday's email I shared what I think is the key feature to making Vue components highly reusable: Scoped slots. But scoped slots are hard to grasp, and even more difficult to master. So today, we're going to make sure we understand them on a deep, intuitive level. Then, I'm going to introduce you to the magic ✨ of scoped slots. The trick is to think of them as functions. Slots are just functions We're going to recreate the functionality of slots, but we'll use a regular Javascript function that only returns HTML. This is the code we'll replicate: <!-- Parent --> < template > < div class = "modal-container" > < div class = "modal" > Content in the Parent < Child class = "mb-4" v-slot = "{ text }" > ...
