Webpack 4 and Babel 7 simple template

This template allows to use ES modules, async/await and css imports based on an index.html template file.

Beware of the "special" config for @babel/preset-env. For generator functions and async/await to work, you need to specify :

presets: [
  [
    '@babel/preset-env',
    {
      targets: {
        node: 'current'
      }
    }
  ]
]
