enforce valid v-if directives

  • ⚙️ 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>
<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 no-parsing-error rule.
