How do I set up a Webpack development server for my React app?

To set up a Webpack development server for your React app, first install Webpack and Webpack Dev Server using npm.

What configurations do I need in my webpack.config.js?

In your webpack.config.js, you'll need to set the entry point, output path, and configure the dev server settings.

Can you give me an example of a basic webpack.config.js file?

Sure! Here's a simple example:

const path = require('path');
module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
    path: path.resolve(__dirname, 'dist'),
  },
  devServer: {
    contentBase: './dist',
  },
};

How do I run the development server after setting it up?

You can run the development server by adding a script in your package.json:

"scripts": {
  "start": "webpack serve"
}

Then, run npm start in your terminal.
