Appearance

vue/valid-v-memo ​

enforce valid v-memo directives

  • ⚙️ This rule is included in all of "plugin:vue/essential", *.configs["flat/essential"], "plugin:vue/strongly-recommended", *.configs["flat/strongly-recommended"], "plugin:vue/recommended" and *.configs["flat/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>
