enforce valid `v-if` directives (vue/valid-v-if)

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

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-if directives. E.g. <div v-else v-if="foo"></div>

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

👎 Examples of incorrect code for this rule:

<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"
/>

👍 Examples of correct code for this rule:
