Я работал над проектом Laravel & Vue js.
Это код Laravel
Код работает хорошо, но в режиме разработчика (проверка) есть предупреждение
Laravel View код
@extends('layouts/app')
@section('content')
<div id="app">
</div>
@endsection
app.js код
const router = new VueRouter({ mode: 'history', routes: routes});
const app = new Vue(Vue.util.extend({ router }, App)).$mount('#app');

Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.
