# vue/valid-v-slot

enforce valid v-slot directives

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>
<template> <!-- ✓ GOOD --> <my-component v-slot="data"> {{data}} </my-component> <my-component> <template v-slot:default> default </template> <template v-slot:one> one </template> <template v-slot:two> two </template> </my-component> <!-- ✗ BAD --> <div v-slot="data"> {{data}} </div> <div> <template v-slot:one> one </template> </div> <my-component v-slot:one="data"> {{data}} </my-component> <my-component v-slot="data"> {{data}} <template v-slot:one> one </template> </my-component> <my-component v-slot:one v-slot:two> one and two </my-component> <my-component> <template v-slot:one> one 1 </template> <template v-slot:one> one 2 </template> </my-component> <my-component> <template v-slot:[data]="data"> dynamic? </template> </my-component> <my-component v-slot.mod="data"> {{data}} </my-component> <my-component v-slot> content </my-component> </template>
