    </body>
    <script src="{{mix('/js/app.js')}}"></script>
</html>

CodePudding user response：

I Think you will need something like this in your app.js file:

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */

import Vue from 'vue';
require('./bootstrap');

Vue.component('mainapp', require('./components/mainapp.vue').dafault)

/**
 * Next, we will create a fresh Vue application instance and attach it to
 * the page. Then, you may begin adding components to this application
 * or customize the JavaScript scaffolding to fit your unique needs.
 */

const app = new Vue({
    el: '#app'
});

Or do it in this way for Vue 3.0 :

require('./bootstrap');

import { createApp } from 'vue';
import mainapp from './components/mainapp.vue';

createApp({
    components: {
        mainapp,
    }
}).mount('#app');
