Vue Tip: When to Use v-if

Michael Hoffmann

@mokkapps

During toggles, v-if entirely creates and destroys the element, including event listeners and child components:

<template>
  <MyComponent v-if="showComponent" />
</template>

v-show creates the element and only toggles its visibility using CSS.

<template>
  <MyComponent v-show="showComponent" />
</template>

Generally speaking, v-if has higher toggle costs while v-show has higher initial render costs. So prefer v-show if you need to toggle something very often and v-if if the condition is unlikely to change at runtime.
