# vue/valid-v-is

> enforce valid `v-is` directives

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

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

## :book: Rule Details

This rule reports `v-is` directives in the following cases:

- The directive has that argument. E.g. `<div v-is:aaa="foo"></div>`
- The directive has that modifier. E.g. `<div v-is.bbb="foo"></div>`
- The directive does not have that attribute value. E.g. `<div v-is></div>`
- The directive is on Vue-components. E.g. `<MyComponent v-is="foo"></MyComponent>`

<eslint-code-block :rules="{'vue/valid-v-is': ['error']}">

```vue
<template>
  <!-- ✓ GOOD -->
  <tr v-is="'blog-post-row'"></tr>
  <tr v-is="foo"></tr>

  <!-- ✗ BAD -->
  <tr v-is:a="foo"></tr>
  <tr v-is.m="foo"></tr>
  <tr v-is></tr>
  <tr v-is=""></tr>
  <MyComponent v-is="foo" />
</template>
```

</eslint-code-block>

::: warning Note
This rule does not check syntax errors in directives because it's checked by [vue/no-parsing-error] rule.
