# vue/valid-v-model

> enforce valid `v-model` directives

- :gear: This rule is included in the following preset configs:
  - `*.configs["flat/essential"]`
  - `*.configs["flat/vue2-essential"]`
  - `*.configs["flat/strongly-recommended"]`
  - `*.configs["flat/vue2-strongly-recommended"]`
  - `*.configs["flat/recommended"]`

  - `"plugin:vue/strongly-recommended"`
  - `"plugin:vue/vue2-strongly-recommended"`
  - `"plugin:vue/recommended"`
  - `"plugin:vue/vue2-recommended"`

This rule checks whether every `v-model` directive is valid.

## :book: 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>`

  <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" />
