Rollup/Vite/Rolldown plugin to generate a stats JSON file with a bundle-stats webpack-compatible structure
Rollup/Vite/Rolldown plugin to generate a stats JSON file with a bundle-stats webpack-compatible structure.
Note
This plugin generates a webpack-compatible stats JSON file for programmatic usage, inspection, or integration with other compatible tools. To analyze your Rollup/Vite/Rolldown bundle, use rollup-plugin-bundle-stats instead.
npm install --dev rollup-plugin-webpack-stats
or
yarn add --dev rollup-plugin-webpack-stats
or
pnpm add -D rollup-plugin-webpack-stats
// rollup.config.js import webpackStatsPlugin from 'rollup-plugin-webpack-stats'; export default { plugins: [ // add it as the last plugin webpackStatsPlugin(), ], };
// vite.config.js import { defineConfig } from 'vite'; import webpackStatsPlugin from 'rollup-plugin-webpack-stats'; export default defineConfig((env) => ({ plugins: [ // Output webpack-stats.json file webpackStatsPlugin(), ], }));

Analyze bundle stats(bundle size, assets, modules, packages) and compare the results between different builds. Support for webpack, rspack, vite, rolldown and rollup.
Output vite/rollup/rolldown stats.
