How do I set up Webpack for a React project?

To set up Webpack for a React project, you'll need to install Webpack and its dependencies. Start by running npm install --save-dev webpack webpack-cli webpack-dev-server.

What about Babel? Do I need it?

Yes, Babel is essential for transpiling your JSX and ES6+ code. Install it with npm install --save-dev babel-loader @babel/core @babel/preset-env @babel/preset-react.

Can you show me a basic Webpack configuration?

Sure! Here's a simple webpack.config.js:

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',
      },
    ],
  },
  resolve: {
    extensions: ['.js', '.jsx'],
  },
};

How do I run my project after setting it up?

You can run your project using the command npx webpack serve to start the development server.
