How do I use Webpack for code splitting?

To use Webpack for code splitting, you can utilize dynamic imports or the SplitChunksPlugin. Would you like a detailed example?

Yes, please provide an example using dynamic imports.

Sure! You can use the import() function to load modules dynamically. For instance:

function loadComponent() {
  return import('./Component.js');
}

This will split the code and load Component.js only when loadComponent is called.

What about using the SplitChunksPlugin?

The SplitChunksPlugin automatically splits your code into smaller chunks. You can configure it in your Webpack config like this:

optimization: {
  splitChunks: {
    chunks: 'all',
  },
},

This will optimize your bundles by creating shared chunks.

Thanks! How can I test if code splitting is working?

You can check the network tab in your browser's developer tools. If code splitting is working, you should see separate chunk files being loaded.
