rollup-plugin-bundle-analyzer

library1.6.6jsnpmunverified

A Rollup plugin that visualizes the size of output files as an interactive zoomable treemap. Version 1.6.6 supports Rollup ^1.20.0 || ^2.0.0 || ^3.0.0, requires Node >=14.0.0, and ships TypeScript types. It provides multiple analyzer modes (server, static, json) and can display input, rendered (minified), and gzipped sizes. Unlike webpack-bundle-analyzer, this plugin is specifically for Rollup/Vite projects and parses minified bundles to show real module sizes. It supports excluding assets via patterns.

Verified usage

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

bundleAnalyzer

✓ import bundleAnalyzer from 'rollup-plugin-bundle-analyzer'

✗ const bundleAnalyzer = require('rollup-plugin-bundle-analyzer')

Default export is the plugin function. CommonJS require may not work in ESM contexts; use dynamic import or import syntax.

default

✓ import bundleAnalyzer from 'rollup-plugin-bundle-analyzer'

✗ import { bundleAnalyzer } from 'rollup-plugin-bundle-analyzer'

The package uses default export, not named export.

type Options

✓ import type { Options } from 'rollup-plugin-bundle-analyzer'

TypeScript types are included; Options type is available for type-checking plugin options.

Configures rollup to generate a static HTML report and a stats JSON file, excluding source maps.

// rollup.config.js import bundleAnalyzer from 'rollup-plugin-bundle-analyzer'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'esm' }, plugins: [ bundleAnalyzer({ analyzerMode: 'static', reportFilename: 'bundle-report.html', generateStatsFile: true, statsFilename: 'stats.json', excludeAssets: '*.map' }) ] };

Debug

Known issues

breakingPlugin does not work with Rollup 4.x. Only supports Rollup ^1.20.0 || ^2.0.0 || ^3.0.0.

fix

Use the official rollup-plugin-analyzer or wait for an update. Alternatively, pin rollup to version 3.x.

affects: >=4.0.0

gotchaOptions object properties are case-sensitive: 'analyzerMode', not 'mode'. 'host', not 'hostname'.

fix

Check your options object keys against the documentation.

affects: >=1.0.0

gotchaThe 'reportFilename' in 'static' mode is relative to the output directory, not the project root.

fix

Use an absolute path or ensure the relative path is correct.

affects: >=1.0.0

deprecatedSome options like 'startAutomatically' and 'openBrowser' are removed in recent versions.

fix

Remove these options. They are no longer supported.

affects: >=1.5.0
