This rule checks whether every v-if directive is valid.
# 📖 Rule Details
This rule reports v-if directives in the following cases:
- The directive has that argument. E.g.
<div v-if:aaa="foo"></div> - The directive has that modifier. E.g.
<div v-if.bbb="foo"></div> - The directive does not have that attribute value. E.g.
<div v-if></div> - The directive is on the elements which have
v-else/v-else-ifdirectives. E.g.<div v-else v-if="foo"></div>
<template>
<!-- ✓ GOOD -->
<div v-if="foo"/>
<div v-else-if="bar"/>
<div v-else/>
<!-- ✗ BAD -->
<div v-if/>
<div v-if:aaa="foo"/>
<div v-if.bbb="foo"/>
<div
v-if="foo"
v-else
/>
<div
v-if="foo"
v-else-if="bar"
/>
</template>

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