# 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>

This rule does not check syntax errors in directives because it's checked by vue/no-parsing-error rule.
