Vue-cli 5 publish a single js and load from html page

I'm develop an app in Vue 2, using webpack. Currently only publish a '.js' file in remote directory, and from a Sharepoint page will be loaded. I'm trying to migrate to Vue 3, but I can't publish only de js file, and it will not loaded from Sharepoint page.

Here my old webpack config for vue 2

var path = require('path')
var webpack = require('webpack')

module.exports = {
    entry: './src/main.js',
    output: {
        path: 'Q:\\js',
        publicPath: '/dist/',
        filename: `appName.${process.env.NODE_ENV === 'production' ? 'prod' : 'jmp'}.js`,
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: [
                    'vue-style-loader',
                    'css-loader'
                ],
            },
            {
                test: /\.scss$/,
                use: [
                    'vue-style-loader',
                    'css-loader',
                    'sass-loader'
                ],
            },
            {
                test: /\.sass$/,

                        // the "scss" and "sass" values for the lang attribute to the right configs here.
                        // other preprocessors should work out of the box, no loader config like this necessary.
                        'scss': [

and my package.json for vue 3

"scripts": {
    "build": "vue-cli-service build",
    "dev": "vue-cli-service build --mode development --watch",
    "serve": "cross-env NODE_ENV=development vue-cli-service serve"
},

Any help?

Thanks in advance

Finally I have found my error. The deployment create 2 files, because in my router I was using lazy load for a component. It was a stupid error from my part. Thanks to IVO GELOV for they comments
