Electron write file when packaged - electron

Question

In electron, how can I write a file when the app is packaged using electron packager.
The following will create and update the file in development. But once I package the app using electron-packager, the file will no longer be created. What do I need to change?
// imports
const path = require('path');
const fs = require('fs');
// create stream for appending to the log file
stream = fs.createWriteStream(
path.join(__dirname, 'logfile.log'),
{
flags:'a'
}
);
// append content to the log file
stream.write('test');
Here's how I package it:
"scripts": {
"start": "electron .",
"pack:win64": "electron-packager . my-app --out=dist/win64 --platform=win32 --arch=x64 --icon=assets/icon.png --prune=true --overwrite --asar"
},

I haven't tried this but perhaps you could use the afterCopy hook to call the function you need?
afterCopy
Array of Functions
An array of functions to be called after your app directory has been
copied to a temporary directory. Each function is called with five
parameters:
buildPath (String): The path to the temporary folder where your app has been copied to
electronVersion (String): The version of electron you are packaging for
platform (String): The target platform you are packaging for
arch (String): The target architecture you are packaging for
callback (Function): Must be called once you have completed your actions
const packager = require('electron-packager')
const { serialHooks } = require('electron-packager/hooks')
packager({
// ...
afterCopy: [serialHooks([
(buildPath, electronVersion, platform, arch) => {
return new Promise((resolve, reject) => {
setTimeout(() => {
console.log('first function')
resolve()
}, 1000)
})
},
(buildPath, electronVersion, platform, arch) => {
console.log('second function')
}
])],
// ...
})
