rollup-plugin-es3

library1.1.0jsnpmunverified

Rollup plugin that removes ES3-incompatible constructs (Object.defineProperty and Object.freeze) from the bundled output. Version 1.1.0 is the latest stable release. It is a lightweight, focused alternative to large transpilers, specifically addressing rollup's __esModule marker and frozen objects for legacy environments.

Verified usage

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

default

✓ import es3 from 'rollup-plugin-es3'

Default export is a function returning a plugin object.

named

✓ import { rollupPluginES3 } from 'rollup-plugin-es3'

✗ const { rollupPluginES3 } = require('rollup-plugin-es3')

Named export available for those who prefer explicit imports.

type

✓ import type { RollupPluginES3Options } from 'rollup-plugin-es3'

TypeScript users can import the options type.

Shows basic usage of the plugin: install, import, and add to rollup plugins array.

import { rollup } from 'rollup'; import es3 from 'rollup-plugin-es3'; const bundle = await rollup({ input: 'src/index.js', plugins: [es3()], }); await bundle.write({ file: 'dist/bundle.js', format: 'iife' });

Debug

Known issues

gotchaPlugin only removes Object.defineProperty and Object.freeze; it does not handle other ES3 incompatibilities like reserved words or trailing commas.

fix

Use additional plugins (e.g., rollup-plugin-es5) for broader ES3 compatibility.

affects: all

breakingv1.0.2 removed support for Object.freeze removal by default (breaking change if relied on).

fix

Update to v1.0.2+; pass { remove: ['freeze'] } to re-enable.

affects: <1.0.2

deprecatedObject.freeze removal is disabled by default since v1.0.2 and may be removed entirely.

fix

Use explicit option { remove: ['freeze'] } if needed.

affects: >=1.0.2

Errors

Common errors & fixes

Error: "Object.defineProperty is not defined"

Plugin not applied or configured incorrectly.

fix

Ensure plugin is installed and added to rollup plugins array: plugins: [es3()]

TypeError: es3 is not a function

Default import used with require instead of import.

fix

Use import es3 from 'rollup-plugin-es3' or const es3 = require('rollup-plugin-es3').default
