rollup-plugin-webpack-stats

A Rollup/Vite/Rolldown plugin (v3.1.1, released April 2026) that generates a stats JSON file with a webpack-compatible structure, enabling use of webpack ecosystem tools like bundle-stats and analyze tools with non-webpack builds. It supports Rollup 3/4, Vite 5-8, and Rolldown 1.0 beta, ships TypeScript types, and offers options like custom filename, asset/module filtering, and transform callback. Unlike direct webpack stats generation, it converts Rollup's output format to the webpack stats schema, making it a bridge tool.
