How to unpack an .asar file?

How do you use Asar Electron?

To use an asar archive to replace the app folder, you need to rename the archive to app. asar , and put it under Electron's resources directory like below, and Electron will then try to read the archive and start from it.

npx asar extract app.asar destfolder 

Extract a particular file:

npx asar extract-file app.asar main.js

It is possible to upack without node installed using the following 7-Zip plugin:
