📖 Rule Details ​

This rule reports event triggers not declared with the emits option. (The emits option is a new in Vue.js 3.0.0+)

Explicit emits declaration serves as self-documenting code. This can be useful for other developers to instantly understand what events the component is supposed to emit. Also, with attribute fallthrough changes in Vue.js 3.0.0+, v-on listeners on components will fallthrough as native listeners by default. Declare it as a component-only event in emits to avoid unnecessary registration of native listeners.

🔧 Options ​

{
  "vue/require-explicit-emits": ["error", {
    "allowProps": false
  }]
}

• "allowProps" ... If true, allow event names defined in props. default false
