Vue Components

Building with Components

Components encapsulate template, logic, and styles into reusable units.

Register globally rarely; prefer local imports in SFCs.

<!-- Parent.vue -->
<script setup>
import Child from './Child.vue'
</script>
<template>
  <Child title="Hello | PHPKINGDOM" />
</template>

Local component import with script setup.
