How do I configure Webpack for a React application?

To configure Webpack for a React app, you'll need to set up a few key files: webpack.config.js, package.json, and install necessary loaders.

What loaders do I need to install?

You'll need babel-loader to transpile your JSX and ES6 code, and style-loader and css-loader for handling CSS files.

Can you show me a basic webpack.config.js example?

Sure! Here's a simple example:

const path = require('path');
module.exports = {
  entry: './src/index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js',
  },
  module: {
    rules: [
      {
        test: /.jsx?$/,
        exclude: /node_modules/, 
        use: 'babel-loader',
      },
      {
        test: /.css$/,
        use: ['style-loader', 'css-loader'],
      },
    ],
  },
  resolve: {
    extensions: ['.js', '.jsx'],
  },
};

What about setting up hot module replacement?

For hot module replacement, you can use the webpack-dev-server. You'll need to install it and add the 'devServer' section in your webpack.config.js.
