ignoredElements
Type: Array<string | RegExp>
Default: []
Usage:
Vue.config.ignoredElements = [
'my-custom-web-component',
'another-web-component',
// Use a `RegExp` to ignore all elements that start with "ion-"
// 2.5+ only
/^ion-/
]
Make Vue ignore custom elements defined outside of Vue (e.g., using the Web Components APIs). Otherwise, it will throw a warning about an Unknown custom element, assuming that you forgot to register a global component or misspelled a component name.
