To include a node module for Babel using webpack, you need to follow these steps:

  1. Install the required packages using npm or yarn:
1
npm install --save babel-loader @babel/core @babel/preset-env webpack


  1. Create a webpack.config.js file in the root directory of your project or update an existing one. This file will define the webpack configuration options. Add the following code:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
module.exports = {
  entry: './src/index.js', // Specify the entry point of your application
  output: {
    path: __dirname + '/dist',
    filename: 'bundle.js'
  },
  module: {
    rules: [
      {
        test: /.js$/, // Apply Babel to all JavaScript files
        exclude: /node_modules/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env'] // Use the preset-env preset
          }
        }
      }
    ]
  }
};


  1. Create a .babelrc file in the root directory of your project. This file will define your Babel configuration options. Add the following code to use the preset-env preset:
1
2
3
{
  "presets": ["@babel/preset-env"]
}


  1. Now, you can import and use the node module in your JavaScript code. The Babel loader configured in the webpack config will transpile the module using the specified presets.
  2. Run webpack to bundle your code:
1
npx webpack


Webpack will build the bundle according to the specified configuration, transpile the code using Babel, and output the bundled file to the dist directory.
