Vue.js encountered an error while trying to load the component: either the template or render function is not

Currently I am delving into the realm of Vue.js paired with Laravel by following this series, where the narrator seems to breeze through without encountering any errors. Unfortunately, when I attempted to change the route, a pesky error made an appearance.

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

The section below showcases code snippets from my app.js:

require('./bootstrap');

window.Vue = require('vue');

import VueRouter from 'vue-router'
Vue.use(VueRouter)

let routes = [{
    path: '/dashboard',
    component: require('./components/Dashboard.vue')
  },
  {
    path: '/profile',
    component: require('./components/Profile.vue')
  }
]

const router = new VueRouter({
  routes
})

Vue.component('example-component', require('./components/ExampleComponent.vue'));

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

In addition, here's a snippet of code extracted from my Dashboard.vue:

<template>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Dashboard Component</div>

                    <div class="card-body">
                        I'm an example component.
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

<script>
  export default {
    mounted() {
      console.log('Component mounted.')
    }
  }
</script>

Lastly, here's a code excerpt from my master.blade.php layout:

//sidebar
<ul>
  <li>
    <router-link to="/dashboard" class="nav-link">Dashboard</li>
  <li>
    <router-link to="/profile" class="nav-link">Profile</li>
</ul>
//content
<div class="container-fluid">
  <router-view></router-view>
</div>

To run the app, I am utilizing localhost:3000with some assistance from browserSync and npm run watch. Could this setup be contributing to the occurrence of the error?

Answer №1

To enhance your component requirements, consider including .default like this:

let pages = [{
    url: '/home',
    content: require('./components/Home.vue').default
  },
  {
    url: '/about',
    content: require('./components/About.vue').default
  }
]

Although it may not directly relate to the question at hand, encountering the error message mentioned above is possible when neglecting to enclose HTML code within <template>...</template> tags. This oversight leads Vue to overlook a defined template through tags or object properties.

To illustrate, suppose we have a file named Dashboard.vue, and the content incorrectly written as follows:

<!-- INCORRECT SYNTAX EXAMPLE: missing <template> tag -->
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">Dashboard Component</div>

                <div class="card-body">
                    I'm an example component.
                </div>
            </div>
        </div>
    </div>
</div>

<script>
  export default {
    mounted() {
      console.log('Component mounted.')
    }
  }
</script>

as opposed to the correct structure below:

<template> <!-- REMEMBER THE <template> TAG, here -->
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Dashboard Component</div>

                    <div class="card-body">
                        I'm an example component.
                    </div>
                </div>
            </div>
        </div>
    </div>
</template> <!-- DON'T FORGET THE </template> TAG, here -->

<script>
  export default {
    mounted() {
      console.log('Component mounted.')
    }
  }
</script>

If the incorrect version were used, one would encounter the error:

// Don't forget to add "import Vue from 'vue'" to display the component!

require('./bootstrap');

window.Vue = require('vue');

import VueRouter from 'vue-router'
Vue.use(VueRouter)

let routes = [{
    path: '/home',
    component: require('./components/Home.vue')
  },
  {
    path: '/about',
    component: require('./components/About.vue')
  }
]

const router = new VueRouter({
  routes
})

Vue.component('example-component', require('./components/ExampleComponent.vue'));

const app = new Vue({

Answer №4

It was bothering me for quite some time, the change is so subtle that I could hardly detect it in two different router files, one of which works while the other doesn't.

Rather than

let routes = [{
    path: '/dashboard',
    component: require('./components/Dashboard.vue')
  }]

you should use

let routes = [{
        path: '/dashboard',
        component:()=> import('./components/Dashboard.vue')
      }]

The key here is that the component property can also accept a function, and within that function, you can return an imported component that will only be loaded when needed. If you use require() directly, the component is loaded immediately.
