Question

I'm trying to run my own webpack-4 + vue app. with this package.json. I hope if I achieve this I can integrate it with an existing ASP.Net-Core app

App.vue
<template>
<div class="example">{{ msg }}</div>
</template>
<script>
export default {
data () {
return {
msg: 'Hello world!'
}
}
}
</script>
<style>
.example {
color: red;
}
</style>
I'm getting the following error:
ERROR in ./src/components/App.vue 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type.
> <template>
| <div class="example">{{ msg }}</div>
| </template>
# ./src/index.js 2:0-47 11:18-30
Running this command node_modules\.bin\webpack --config webpack.config.js --mode development it should be able to work but it doesn't.
These are specifications:
node: v8.11.2
webpack 4.17.2
vuejs 2.5.17
Anything else you want to know, please tell me.

Answer 1

For anyone else that runs into this issue, newer versions of vue-loader need to be loaded in the webpack plugins section:
// Required for vue-loader v15
const VueLoaderPlugin = require('vue-loader/lib/plugin')
environment.plugins.append(
'VueLoaderPlugin',
new VueLoaderPlugin()
)

It looks like you don’t have a rule configured for .vue files: you have one for .vue.html files but not for just .vue files. You can just change your existing rule by removing the \.html in order to make it work.
