rollup-plugin-bundle-size

library1.0.3jsnpmunverified

A Rollup plugin that displays the size of the generated bundle(s) after build. v1.0.3 (last release). It provides a simple, no-frills way to see bundle size in the console output. Unlike more comprehensive tools like rollup-plugin-visualizer, it focuses solely on size reporting without additional analysis. Works with Rollup's plugin system. No recent updates; considered stable but minimal.

Verified usage

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

bundleSize

✓ import bundleSize from 'rollup-plugin-bundle-size'

✗ const bundleSize = require('rollup-plugin-bundle-size')

Default export; ESM import works if using native ES modules. CommonJS require works with Rollup's CJS handling.

bundleSize

✓ const bundleSize = require('rollup-plugin-bundle-size')

✗ import { bundleSize } from 'rollup-plugin-bundle-size'

CommonJS require works. Named import is incorrect; it's a default export.

bundleSize

✓ import bundleSize from 'rollup-plugin-bundle-size'

✗ import bundleSize from 'rollup-plugin-bundle-size/bundle-size'

No subpath exports; just import from the package name.

Shows how to integrate bundleSize plugin in Rollup config to log bundle size after build.

import bundleSize from 'rollup-plugin-bundle-size'; export default { input: 'src/index.js', output: { file: 'dist/bundle.js', format: 'cjs' }, plugins: [bundleSize()] };

Known issues

deprecatedPlugin may be unmaintained; no updates since 2019.

fix

Consider using rollup-plugin-visualizer or rollup-plugin-filesize for active maintenance and more features.

affects: *

gotchaThe plugin only shows size for the first output bundle; does not report multiple outputs.

fix

Use a workaround or switch to an alternative if you have multiple output targets.

affects: *

gotchaOutput format may not reflect tree-shaken size accurately for ESM outputs.

fix

Verify size with actual bundle inspection or use a more detailed analyzer.
