enforce valid v-model 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-model directive is valid.

📖 Rule Details ​

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

  • The directive used on HTMLElement has an argument. E.g. <input v-model:aaa="foo">
  • The directive used on HTMLElement has 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()">, <input v-model="a?.b">
  • The directive has potential null object property access. E.g. <input v-model="(a?.b).c">
  • 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" /> <MyComponent v-model:propName="foo" /> <MyComponent v-model.modifier="foo" /> <MyComponent v-model:propName.modifier="foo" /> <div v-for="todo in todos"> <input v-model="todo.name" /> </div> <!-- ✗ BAD --> <input v-model /> <input v-model:aaa="foo" /> <input v-model.bbb="foo" /> <input v-model="foo + bar" /> <input v-model="a?.b.c" /> <input v-model="(a?.b).c" /> <div v-model="foo" /> <div v-for="todo in todos"> <input v-model="todo" /> </div> </template>
