## What it is
A Webpack plugin that generates an asset manifest mapping source filenames to hashed build output files. It emits a manifest.json (customizable) during webpack builds to support caching and asset lookup.

## Use cases
- generate a manifest mapping source files to hashed webpack output filenames
- track build assets for server-side rendering or CDN deployment
- integrate webpack build output with a backend that needs asset paths
- filter or prefix manifest keys for a custom deployment layout
- consume emitted assets in another webpack plugin via asset hooks

## When to choose
- you use Webpack 5 and need a reliable mapping of original files to emitted, hashed assets
- you deploy assets to a CDN or cache-bust and need a manifest consumed by your server
- you need fine-grained control over manifest keys, filtering, and generation stage

## When to avoid
- you have migrated off webpack to Vite, esbuild, or another bundler with native manifest support
- you need a runtime asset loader rather than a build-time manifest file
- you are on Node.js older than v20.19 or webpack below v5

- artifact type: plugin
