What are the differences between JavaScript module bundlers?

JavaScript module bundlers like Webpack, Rollup, and Parcel each have unique features. Webpack is highly configurable and great for large applications, while Rollup is optimized for libraries and offers tree-shaking. Parcel is user-friendly and requires minimal configuration. What specific features are you interested in?

I'm particularly interested in performance and ease of use.

In terms of performance, Rollup often produces smaller bundles due to its tree-shaking capabilities. Webpack can be optimized but may require more setup. For ease of use, Parcel stands out with zero configuration needed to get started. Would you like to know more about setting them up?

Yes, how do I set up Webpack for a simple project?

To set up Webpack, first install it via npm: npm install --save-dev webpack webpack-cli. Then create a webpack.config.js file to define your entry and output points. Finally, run npx webpack to bundle your project. Would you like a sample configuration?

That would be great! Can you provide an example?

Sure! Here's a basic example of a webpack.config.js:

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

This configuration takes index.js from the src folder and outputs bundle.js in the dist folder.
