The AutomaticPrefetchPlugin discovers all modules from the previous compilation upfront while watching for changes, trying to improve the incremental build times. Compared to PrefetchPlugin which discovers a single module upfront.
May or may not have a performance benefit since the incremental build times are pretty fast.
webpack.config.js
module.exports = {
  // ...
  plugins: [
    new webpack.AutomaticPrefetchPlugin()
  ]
};
