What it is and what it does
jsbeautifier is a Python package that reformats and deobfuscates JavaScript code. It takes minified, obfuscated, or packed JavaScript and outputs human-readable code with proper indentation and formatting. The package is designed to handle output from popular online obfuscators, making it useful for code analysis, security review, or recovering readable source from minified distributions.
The package has a single runtime dependency on editorconfig and installs with low friction. It has been actively maintained since its initial release in 2013, with recent activity indicating ongoing support.
Use it for
- Reverse-engineer minified JavaScript from production websites for security auditing
- Unpack obfuscated malware samples for analysis and threat intelligence
- Recover readable source code from packed or compressed JavaScript libraries
- Format and debug JavaScript that has been processed through online obfuscators
- Automate beautification of JavaScript in build pipelines or CI/CD workflows
