To include a node module for Babel using webpack, you need to follow these steps:
- Install the required packages using npm or yarn:
1
|
npm install --save babel-loader @babel/core @babel/preset-env webpack
|
- 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

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
}
}
}
]
}
};
|
- 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

|
{
"presets": ["@babel/preset-env"]
}
|
- 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.
- Run webpack to bundle your code:
Webpack will build the bundle according to the specified configuration, transpile the code using Babel, and output the bundled file to the dist
directory.
