My electron application is insanely big on Mac after installation. It's around 1.39GB for no apparent reason, even though it's around 70MB on Windows. I tried to unpack the dmg file to see what makes it so big then found a file called app.asar that takes a large size of the app (1.22GB) and I don't know how to unpack this file. So my question is, How to make the application's size much smaller like on windows? and what does app.asar file contain?
I'm using electron-builder to build the app by the way
It depends on your app.
If your app is too heavy, then it might be natural.
If not; try removing unwanted packages in the node_modules directory using npm.
Try instructions here :

You can also unpack the asar file using:
npx asar extract app.asar destfolder
more on that here How to unpack an .asar file?
it basically contains all you code and stuff.
I hope I could help you 😉.
