webpack-deadcode-plugin

Webpack plugin (v0.1.17) that detects unused files and unused exports in used files during the webpack build process. It outputs warnings to the terminal without failing the build unless configured otherwise. Works with webpack 3, 4, and 5 via peer dependency. Key differentiators: supports both file and export detection, integrates with TypeScript loaders (with caveats), offers granular logging and JSON export. Active development with periodic releases.
