rollup-plugin-webpack-stats

library3.1.1jsnpmunverified

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.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default

✓ import webpackStatsPlugin from 'rollup-plugin-webpack-stats'

✗ const webpackStatsPlugin = require('rollup-plugin-webpack-stats')

ESM-only since v3.0.0; CJS require will fail.

webpackStatsPlugin

✓ import webpackStatsPlugin from 'rollup-plugin-webpack-stats'

✗ import { webpackStatsPlugin } from 'rollup-plugin-webpack-stats'

Default export only; named import not supported.

WebpackStatsPluginOptions

✓ import type { WebpackStatsPluginOptions } from 'rollup-plugin-webpack-stats'

TypeScript type import for options object.

Shows basic setup for Rollup and Vite config files. Plugin must be the last in the plugins array to capture final bundle stats.

// rollup.config.js import webpackStatsPlugin from 'rollup-plugin-webpack-stats'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'esm' }, plugins: [ // Must be last plugin webpackStatsPlugin() ] }; // vite.config.js import { defineConfig } from 'vite'; import webpackStatsPlugin from 'rollup-plugin-webpack-stats'; export default defineConfig(() => ({ plugins: [ webpackStatsPlugin() ] }));
