What is OpenAsar?
OpenAsar is an open-source tool that provides full support for working with ASAR archives used by Electron apps. ASAR (Atom Shell Archive Format) is a zip-based packaging format created by GitHub for Electron apps.
With OpenAsar, developers can extract the contents of ASAR files, make modifications, and repackage the app easily. This gives more transparency and flexibility compared to the closed proprietary ASAR format.
Key features of OpenAsar include:
- Unpacking ASAR files while preserving permissions and symlinks
- Repacking modified files back into the ASAR archive
- Asar command line tool for manipulation without needing to write code
- Node.js API for programmatic ASAR file handling
- Support for patching ASAR content without full repacking
By providing an open replacement for ASAR, OpenAsar makes it simpler for developers to inspect, customize, and debug Electron app packages. It removes limitations imposed by the closed-source ASAR implementation.
