Webpack without .babelrc

Following my previous note: Hello Preact Modules.

We can avoid the .babelrc file by adding these configuration to the webpack.config.js file.

.babelrc file:

{
  "presets": [
    "@babel/preset-env"
  ],
  "plugins": [
    ["@babel/plugin-transform-react-jsx", {
      "pragma": "h"
    }],
  ]
}

Below there's the new webpack.config.js file.

module.exports = {
  entry: './app.js',
  output: {
    path: __dirname,
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /\.js$/,
-       loader: 'babel-loader',
+       use: {
+         loader: 'babel-loader',
+         options: {
+           presets: [
+             '@babel/preset-env'
+           ],
+           plugins: [
+             ['@babel/plugin-transform-react-jsx', {
+               'pragma': 'h'
+             }],
+           ]
+         }
        }
      }
    ]
  }
}

Now we can delete .babelrc, and everything should work the same.
