# vue/valid-v-memo

enforce valid v-memo directives

⚙️ This rule is included in all of "plugin:vue/vue3-essential", "plugin:vue/vue3-strongly-recommended" and "plugin:vue/vue3-recommended".

This rule checks whether every v-memo directive is valid.

# 📖 Rule Details

This rule reports v-memo directives in the following cases:

The directive has that argument. E.g. <div v-memo:aaa></div>
The directive has that modifier. E.g. <div v-memo.bbb></div>
The directive does not have that attribute value. E.g. <div v-memo></div>
The attribute value of the directive is definitely not array. E.g. <div v-memo="{x}"></div>
The directive was used inside v-for. E.g. <div v-for="i in items"><div v-memo="[i]" /></div>

<template>
  <!-- ✓ GOOD -->
  <div v-memo="[x]"/>

  <!-- ✗ BAD -->
  <div v-memo/>
  <div v-memo:aaa="[x]"/>
  <div v-memo.bbb="[x]"/>
  <div v-memo="{x}"/>
  <div v-for="i in items">
    <div v-memo="[i]" />
  </div>
</template>
