enforce valid v-model 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-model directive is valid.

📖 Rule Details

This rule reports v-model directives in the following cases:

  • The directive has that argument. E.g. <input v-model:aaa="foo">
  • The directive has the modifiers which are not supported. E.g. <input v-model.bbb="foo">
  • The directive does not have that attribute value. E.g. <input v-model>
  • The directive does not have the attribute value which is valid as LHS. E.g. <input v-model="foo() + bar()">
  • The directive is on unsupported elements. E.g. <div v-model="foo"></div>
  • The directive is on <input> elements which their types are file. E.g. <input type="file" v-model="foo">
  • The directive's reference is iteration variables. E.g. <div v-for="x in list"><input type="file" v-model="x"></div>
<template> <!-- ✓ GOOD --> <input v-model="foo"> <input v-model.lazy="foo"> <textarea v-model="foo"/> <MyComponent v-model="foo"/> <div v-for="todo in todos"> <input v-model=""> </div> <!-- ✗ BAD --> <input v-model> <input v-model:aaa="foo"> <input v-model.bbb="foo"> <input v-model="foo + bar"> <div v-model="foo"/> <div v-for="todo in todos"> <input v-model="todo"> </div> </template>

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