The function createVNode does not exist in the context of Vue integrated with Laravel

I've been attempting to replicate a component rendering based on an online example.

While it works smoothly in a sample project, it crashes when applied to the official codebase.

Here is the content of the blade file being rendered:

<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Vue SPA Demo</title>
</head>
<body>
    <div id="app">
        asdfsadfsadsdf
        <example-component></example-component>
    </div>

    <script src="js/app.js"></script>
</body>
</html>

Next up, here's app.js:

window.Vue = require("vue").default;
import ExampleComponent from './components/ExampleComponent.vue';

Vue.component('example-component', ExampleComponent);

And now, let's take a look at ExampleComponent.vue:

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

This visualizes what the page should appear like:

and below is the encountered error: https://i.sstatic.net/y8oGl.png

A noteworthy observation: when I attempt this alternate method of including the component, namely, displaying "Test":

Vue.component('example-component', {
    template: '<div>Test</div>'
});

it becomes evident that the issue lies within this specific line/file:

import ExampleComponent from './components/ExampleComponent.vue';

Answer №1

Finally, success is mine! After a grueling 8 hours of troubleshooting...

The culprit turned out to be the "vue-loader" version 16.1.2 in the package.json. I experimented with switching between "16.1.2" and "15.9.2" multiple times, executing

rm -rf node_modules/
rm package-lock.json
npm cache clear --force
npm install

after each change.

Interesting fact: following this process will ensure that your component renders correctly when you input

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

into your app.js file.
