## What it is
A webpack plugin that automatically injects <link rel='preload'> and <link rel='prefetch'> tags for asynchronous JavaScript chunks into HTML generated by html-webpack-plugin. It simplifies wiring up lazy-loaded, hash-named chunks for better page performance.

## Use cases
- automatically add preload links for async webpack chunks
- wire up lazy-loaded routes with resource hints
- prefetch webpack chunks with hashed filenames
- improve initial page load performance with preload
- inject resource hints into html-webpack-plugin output

## When to choose
- you maintain a legacy webpack 4 project already using html-webpack-plugin and need preload/prefetch wiring

## When to avoid
- starting a new project - use the maintained fork at vuejs/preload-webpack-plugin instead
- you are not using webpack with html-webpack-plugin
- you need webpack 5 support or active maintenance
