  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {

});

module.exports = {
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {

      }
    ]
  },

Generate webpack files

npm run build

Add Sanic server file

Make sure you have atleast Python 3.5 first! Save the following as requirements.txt

aiohttp==3.4.4
sanic==0.8.1

run the following command

pip3 install requirements.txt

Change your package.json start to:

"start": "python3 server.py",

Make your server.py file

from sanic import Sanic
from sanic.response import json, html, file, text
import aiohttp
import asyncio

# gets current directory
BASE = os.getcwd()

app = Sanic()
app.static('/src', BASE + '/src')

# serve js file for webpack
app.static('/', BASE)
app.static('/main.js', './dist/main.js', name='main.js')

@app.route('/')
async def index(request):
    return await file('./dist/index.html')


if __name__ == '__main__':
    app.run(
        host='0.0.0.0',
        port=int(os.environ.get('PORT', 8000)),
        workers=int(os.environ.get('WEB_CONCURRENCY', 1)),
        debug=bool(os.environ.get('DEBUG', '')))

RUN IT!
