Adding React

Install React:

npm install react react-dom --save-dev

Install the Babel preset to process React JSX code:

npm install @babel/preset-react --save-dev

Add the React preset to Babel. It will convert React (JSX) code to raw JavaScript:

module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /(node_modules)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-react', '@babel/preset-env']
          }
        }
      }
    ]
  }
