How do I use Webpack Bundle Analyzer?

What is Webpack Bundle Analyzer and how can I use it?

Webpack Bundle Analyzer is a tool that helps you visualize the size of your webpack output files. You can use it to identify which modules are taking up the most space in your bundle.

How do I install it in my project?

You can install it using npm with the command: npm install --save-dev webpack-bundle-analyzer. After that, you can configure it in your webpack config file.

Can you show me an example of how to configure it?

Sure! In your webpack.config.js, you can add the following code:

const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;

module.exports = {
  plugins: [
    new BundleAnalyzerPlugin()
  ]
};

This will generate a report after you build your project.

What kind of insights can I get from the report?

The report will show you a visual representation of your bundle, including the size of each module, which helps you identify large dependencies and optimize your bundle size.
