Laravel - [Vue alert]: Unable to bind component: template or rendering function is missing

I am venturing into the world of Single Page Applications with Laravel and Vue for the first time. Instead of using webpack, I opted to go with Laravel Mix. Unfortunately, it seems like things have gone awry as I am now encountering the following error:

[Vue warn]: Failed to mount component: template or render function not defined.

This issue arises when I try to include

<router-view></router-view>
in my code.

I attempted a workaround by adding .default, but unfortunately, that did not resolve the problem.

export default new VueRouter({
    routes: [
        {
            path: '/',
            component: require('./views/Home.vue').default
        },
        {
            path: '/about',
            component: require('./views/About.vue').default
        }
    ]
});

Here is a snippet from my app.js file:

import './bootstrap';
import router from './routes';

new Vue({
    el: '#app',
    router,
});

And here is the content of my bootstrap.js file:

import Vue from 'vue';
import VueRouter from 'vue-router';
import axios from 'axios';


window.Vue = Vue;
Vue.use(VueRouter);

window.axios = axios;

window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

let token = document.head.querySelector('meta[name="csrf-token"]');

if (token) {
    window.axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;
} else {
    console.error('CSRF token not found: https://laravel.com/docs/csrf#csrf-x-csrf-token');
}

My routes.js file looks like this:

import VueRouter from 'vue-router';

export default new VueRouter({
    routes: [
        {
            path: '/',
            component: require('./views/Home.vue')
        }
    ]
});

For the HTML part (welcome.blade.php), here is what I have:

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>Laravel</title>
        <link rel="stylesheet" href="/css/app.css" type="text/css">
    </head>
    <body>
        <div id="app">
            <router-link to="/">Home</router-link>

            <router-view></router-view>
        </div>
        <script src="/js/app.js"></script>
    </body>
</html>

Answer №1

To optimize bootstrap.js, remove the lines

import VueRouter from 'vue-router';
and Vue.use(VueRouter);. Instead, integrate the Router plugin directly into Vue within the routes.js file with the following modifications:

import Vue from 'vue';
import VueRouter from 'vue-router';

Vue.use(VueRouter);
export default new VueRouter({
    routes: [
        {
            path: '/',
            component: require('./views/Home.vue')
        }
    ]
});

The implementation of app.js is accurate. In my testing, everything functioned as intended.

Answer №2

Here's the solution I implemented to resolve the problem:

To address the issue, I included .default after calling

require('./components/ExampleComponent.vue')
, resulting in
require('./components/ExampleComponent.vue').default

Answer №3

Use relative paths instead of webpack resolve aliases

I encountered an issue related to the webpack [chunkhash] placeholder causing problems in the output.chunkFilename webpack option

Adjusting webpack optimization.splitChunks.chunks setting

const mix = require('laravel-mix');
const fs = require('fs');
const webpack = require('webpack');
const tailwind = require('tailwindcss');
const path = require('path');
const glob = require('glob');
const exec = require('child_process').exec;
const pwa = require('sw-precache-webpack-plugin');

mix.webpackConfig({
    output: {
        chunkFilename: 'js/[name].js',
    },
    plugins: [
        new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
    ],
});

mix.version();

// ...

mix.js('resources/js/app/app.js', 'public/js/app.js');
