verified May 27, 2026

A webpack plugin to detect and report duplicated dependencies in the bundle. Version 1.0.2, stable, maintained sporadically. Key differentiator: provides a hook-based architecture for custom reporting, unlike simpler duplicates plugins that only warn. Allows programmatic access to duplicate package data (name, version, root path, bytes) for integration with custom reporters or CI checks. Primarily used in webpack 4 and 5 projects to audit dependency duplication.
