rollup-plugin-javascript-obfuscator

library1.0.4jsnpmunverified

A Rollup plugin that uses javascript-obfuscator to obfuscate bundled JavaScript code. Version 1.0.4 (latest) wraps javascript-obfuscator v4.x, allowing control over obfuscation options directly in the Rollup build pipeline. It supports source maps (inline or separate) and enables protection of emitted code with minimal setup. Differentiates by tightly integrating obfuscation within the bundle output, rather than requiring a separate post-build step.

Verified usage

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

obfuscatorPlugin

✓ import obfuscatorPlugin from 'rollup-plugin-javascript-obfuscator'

✗ import { obfuscatorPlugin } from 'rollup-plugin-javascript-obfuscator'

Default export, not named. Use this for ESM.

obfuscatorPlugin (require)

✓ const obfuscatorPlugin = require('rollup-plugin-javascript-obfuscator')

✗ const { obfuscatorPlugin } = require('rollup-plugin-javascript-obfuscator')

For CommonJS environments like Node.js with CJS.

rollup

✓ import { rollup } from 'rollup'

✗ import rollup from 'rollup'

Rollup main export is named, not default.

Complete Rollup build pipeline with obfuscation plugin applied to ES module bundle.

import { rollup } from 'rollup'; import obfuscatorPlugin from 'rollup-plugin-javascript-obfuscator'; async function build() { const bundle = await rollup({ input: 'src/index.js', plugins: [ obfuscatorPlugin({ compact: true, controlFlowFlattening: false, stringArrayEncoding: ['base64'] }) ] }); await bundle.write({ file: 'dist/bundle.js', format: 'esm' }); } build().catch(console.error);

Debug

Known issues

gotchaObfuscation can significantly increase bundle size and reduce runtime performance

fix

Use obfuscator options judiciously; avoid high-complexity transforms like controlFlowFlattening if performance is critical

affects: >=0.0.0

breakingThe plugin expects javascript-obfuscator v4.x. Install it explicitly if not already present.

fix

npm install --save-dev javascript-obfuscator@^4.0.0

affects: >=1.0.0

deprecatedThe 'entry' option used in example README is deprecated in Rollup v2+

fix

Replace 'entry' with 'input'

affects: >=0.66.0

gotchaSource maps may not work correctly if obfuscation corrupts mappings

fix

Test with source map enabled; use inline source maps for simpler setup

affects: >=0.0.0

breakingThe package does not export TypeScript definitions

fix

Create a custom declaration file or use @ts-ignore

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'javascript-obfuscator'

Missing peer dependency

fix

npm install --save-dev javascript-obfuscator

TypeError: obfuscatorPlugin is not a function

Incorrect import (named instead of default)

fix

Use default import: import obfuscatorPlugin from 'rollup-plugin-javascript-obfuscator'

Error: The 'entry' option is deprecated. Use 'input' instead.

Used deprecated Rollup option 'entry'

fix

Replace 'entry' with 'input' in your rollup configuration
