How do I use Webpack for cache busting?

To use Webpack for cache busting, you can utilize the output.filename option with a content hash. This ensures that the filename changes whenever the content changes.

Can you show me an example of how to set that up?

Sure! In your Webpack configuration, you can set it up like this:

module.exports = {
  output: {
    filename: '[name].[contenthash].js',
    path: path.resolve(__dirname, 'dist'),
  },
};

What about CSS files? How can I apply cache busting to them?

For CSS, you can use the MiniCssExtractPlugin. Set it up like this:

const MiniCssExtractPlugin = require('mini-css-extract-plugin');

module.exports = {
  plugins: [
    new MiniCssExtractPlugin({
      filename: '[name].[contenthash].css',
    }),
  ],
};

Is there anything else I should consider for cache busting?

Yes, consider using the HtmlWebpackPlugin to automatically inject your hashed files into your HTML, ensuring that users always get the latest versions.
