Electron modify file store in .asar

Question

I would like, from the Electron index.html file, to modify a config file present in the .asar of my application. In my case I need to change, if necessary, my application database config in order to work.

I understood that .asar is in readOnly and I wanted to know if there is a way to modify this config file from Electron without changing its position in my application?

I see the extraResources option but I did not understand how it works.

It's also important that the config file stay in myapp/config folder.

Thanks for your help :)

What build tool do you use? If you are using electron builder, you can check out asarUnpack in configuration file here or extraFiles here
