vue/valid-v-slot

enforce valid v-slot directives

⚙️ This rule is included in all of "plugin:vue/vue3-essential", *.configs["flat/essential"], "plugin:vue/essential", *.configs["flat/vue2-essential"], "plugin:vue/vue3-strongly-recommended", *.configs["flat/strongly-recommended"], "plugin:vue/strongly-recommended", *.configs["flat/vue2-strongly-recommended"], "plugin:vue/vue3-recommended", *.configs["flat/recommended"], "plugin:vue/recommended" and *.configs["flat/vue2-recommended"].

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

📖 Rule Details

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

The directive is not owned by a custom element. E.g. <div v-slot=""></div>
The directive is a named slot and is on a custom element directly. E.g. <my-component v-slot:foo></my-component>
The directive is the default slot, is on a custom element directly, and there are other named slots. E.g. <my-component v-slot=""><template v-slot:foo></template></my-component>
The element which has the directive has another v-slot directive. E.g. <my-component v-slot:one v-slot:two></my-component>
The element which has the directive has another v-slot directive that is distributed to the same slot. E.g. <my-component><template v-slot:foo></template><template v-slot:foo></template></my-component>
The directive has a dynamic argument which uses the scope properties that the directive defined. E.g. <my-component><template v-slot:[data]="data"></template></my-component>
The directive has any modifier. E.g. <my-component v-slot.foo></my-component>
The directive is the default slot, is on a custom element directly, and has no value. E.g. <my-component v-slot></my-component>

Note

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

json

{
  "vue/valid-v-slot": ["error", {
    "allowModifiers": false
  }]
}

allowModifiers (boolean) ... allows having modifiers in the argument of v-slot directives. Modifiers just after v-slot are still disallowed. E.g. <template v-slot.foo> default false.
