rollup-plugin-post-obfuscator

library1.0.0jsnpmunverified

Rollup plugin that obfuscates JavaScript output after the bundle is generated. Current stable version is 1.0.0. It leverages javascript-obfuscator under the hood and supports dynamic import obfuscation, inclusion/exclusion patterns, and source map handling. Unlike other obfuscation plugins that operate during the build process, this plugin post-processes the output, making it compatible with various output formats and easier to integrate. It ships TypeScript types and requires Node >=16 and Rollup <5.

Verified usage

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

default (obfuscator)

✓ import obfuscator from 'rollup-plugin-post-obfuscator'

✗ const obfuscator = require('rollup-plugin-post-obfuscator')

Plugin uses ESM only; CJS require may fail in older Node versions <16.

default in Rollup config

✓ import obfuscator from 'rollup-plugin-post-obfuscator'; export default { plugins: [obfuscator()] }

✗ import { obfuscator } from 'rollup-plugin-post-obfuscator'

The plugin is exported as default, not named.

TypeScript type

✓ import type { ObfuscatorOptions } from 'rollup-plugin-post-obfuscator'

For TypeScript, use type import for options types.

Basic Rollup config using the obfuscator plugin with typical options including include/exclude patterns and custom javascript-obfuscator options.

// rollup.config.js import obfuscator from 'rollup-plugin-post-obfuscator'; export default { input: 'src/index.js', output: { dir: 'dist', format: 'es', }, plugins: [ obfuscator({ outDir: 'dist', include: ['**/*.js'], exclude: ['vendor/**'], JavaScriptObfuscatorOptions: { compact: true, controlFlowFlattening: true, }, }), ], };

Debug

Known issues

gotchaPlugin requires Rollup <5; using with Rollup 5 will cause a peer dependency warning and may break.

fix

Use Rollup 4 or earlier.

affects: >=1.0.0

gotchaThe 'outDir' option must match Rollup's output.dir exactly; otherwise, the plugin may fail to find generated files.

fix

Set obfuscator({ outDir: output.dir }) or ensure consistency.

affects: >=1.0.0

gotchaObfuscation of source maps is not well documented; if source maps are enabled, the plugin may not update them correctly.

fix

Test with source maps or disable them if obfuscation breaks them.

affects: >=1.0.0

gotchaDynamic import obfuscation may not work reliably with all output formats (e.g., SystemJS).

fix

Test with your specific format; consider using 'es' or 'cjs'.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'rollup-plugin-post-obfuscator'

Missing npm install or using wrong package name.

fix

Run 'npm install --save-dev rollup-plugin-post-obfuscator'

TypeError: obfuscator is not a function

Named import instead of default import.

fix

Use 'import obfuscator from ...' not '{ obfuscator }'.

ERR_PEER_DEP_INVALID: rollup@5.0.0 invalid for rollup-plugin-post-obfuscator@1.0.0

Plugin requires Rollup <5, but Rollup 5 is installed.

fix

Downgrade Rollup to 4.x.
