    // Also exclude `html` and `json` extensions so they get processed

    // by webpacks internal loaders.

    exclude: [/\.(js|mjs|jsx|ts|tsx)$/, /\.html$/, /\.json$/],

    options: {

      name: 'static/media/[name].[hash:8].[ext]',

  },

  // Make sure to add the new loader(s) before the "file" loader.

  loaders: ['style-loader', 'css-loader', 'sass-loader']
