preload-webpack-plugin

Preload-webpack-plugin (v2.3.0) enhances html-webpack-plugin by adding link rel=preload and prefetch resource hints for scripts and other assets. It integrates with webpack 3 and is developed by Google Chrome Labs. The v3 alpha/beta branches add webpack 4 support and target node >= 6. Key differentiators: automatic preloading of async chunks, granular control via include/exclude options, and support for multiple HtmlWebpackPlugin instances. Unlike manual preloading, it covers all script types (initial, async, dynamic) with minimal config.
