require type definitions in emits

# 📖 Rule Details

This rule enforces that a emits statement contains type definition.

Declaring emits with types can bring better maintenance. Even if using with TypeScript, this can provide better type inference when annotating parameters with types.

<script> /* ✓ GOOD */ Vue.component('foo', { emits: { // Emit with arguments foo: (payload) => { /* validate payload */ }, // Emit without parameters bar: () => true, } }) /* ✗ BAD */ Vue.component('bar', { emits: ['foo'] }) Vue.component('baz', { emits: { foo: null, } }) </script>
