enforce valid `v-on` directives (vue/valid-v-on)

⚙️ This rule is included in all of "plugin:vue/essential", "plugin:vue/strongly-recommended" and "plugin:vue/recommended".

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

📖 Rule Details

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

The directive does not have that event name. E.g. <div v-on="foo"></div>
The directive has invalid modifiers. E.g. <div v-on:click.bbb="foo"></div>
The directive does not have that attribute value and any verb modifiers. E.g. <div v-on:click></div>

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

👎 Examples of incorrect code for this rule:

<div v-on/>
<div v-on:click/>
<div v-on:click.aaa="foo"/>
<div @click/>

👍 Examples of correct code for this rule:

<div v-on="foo"/>
<div v-on:click="foo"/>
<div @click="foo"/>
<div @click.left="foo"/>
<div @click.prevent/>
<div @click.stop/>

This rule has an object option:

"modifiers": [] (default) array of additional allowed modifiers.

"vue/valid-v-on": [2, {
  modifiers: ['foo']
}]

👍 Examples of correct code for this rule:

<div @click.foo="foo"/>
<div v-on:click.foo="foo"/>
