I recently tested it on a real-world example: a Vue 2 + Three.js tower defense game that was bundled into a single webpack file
The tool attempts to:
recover module boundaries rebuild a project-like structure restore variable and function naming
In this case, it managed to reconstruct most of the project:
~90% file mapping ~93% naming recovery core game logic preserved
Example repo (with before/after): https://github.com/zhongguagua/jsunpack-example
It’s still very much a work in progress, and there are limitations (missing imports, some incorrect mappings, etc).
Curious to hear feedback from people who have worked with reverse engineering or JS tooling.
