Asar7z !!install!! -

If you regularly work with ASAR files, give Asar7z a try—you might find it replaces your old npx asar commands for good. Note: Asar7z is an independent open-source project. Always ensure you have the right to unpack or modify any third-party ASAR archives, as many Electron apps are proprietary software.

asar7z pack ./source_folder app.asar --method lzma --level 9 asar7z

asar7z x app.asar -o ./output_folder
