enforce valid v-else-if directives

  • ⚙️ This rule is included in all of "plugin:vue/essential", *.configs["flat/essential"], "plugin:vue/vue2-essential", *.configs["flat/vue2-essential"], "plugin:vue/strongly-recommended", *.configs["flat/strongly-recommended"], "plugin:vue/vue2-strongly-recommended", *.configs["flat/vue2-strongly-recommended"], "plugin:vue/recommended", *.configs["flat/recommended"], "plugin:vue/vue2-recommended" and *.configs["flat/vue2-recommended"].

This rule checks whether every v-else-if directive is valid.

📖 Rule Details ​

This rule reports v-else-if directives in the following cases:

  • The directive has that argument. E.g. <div v-if="foo"></div><div v-else-if:aaa="bar"></div>
  • The directive has that modifier. E.g. <div v-if="foo"></div><div v-else-if.bbb="bar"></div>
  • The directive does not have that attribute value. E.g. <div v-if="foo"></div><div v-else-if></div>
  • The directive is on the elements that the previous element don't have v-if/v-else-if directives. E.g. <div v-else-if="bar"></div>
  • The directive is on the elements which have v-if/v-else directives. E.g. <div v-if="foo" v-else-if="bar"></div>
<template> <!-- ✓ GOOD --> <div v-if="foo" /> <div v-else-if="bar" /> <!-- ✗ BAD --> <div /><div v-else-if="foo" /> <div v-if="x" /><div v-else-if /> <div v-if="x" /><div v-else-if:aaa="foo" /> <div v-if="x" /><div v-else-if.bbb="foo" /> </template>
