Running 'cordova prepare electron' on an clean source control electron project with supported plugin fails to write to package.json.
Bug Report
Problem
In a Cordova project which has been retrieved from source control (eg, no platforms or plugin directory) cordova prepare electron
when using a plugin which supports the new electron 3.0 plugin model throws an error trying to write to package.json.
What is expected to happen?
Cordova successfully prepares the electron platform with the cordova-plugin-device plugin.
What does actually happen?
npx cordova prepare electron
npx: installed 495 in 39.075s
Discovered platform "electron". Adding it to the project

Information
I found the issue working on a native file system plugin for electron and was able to reproduce it with cordova-plugin-device since it was upgraded. When you install electron and then add the plugin everything works fine because the package json is already there. In the situation of source control and build servers however it fails because prepare which also installs plugins have a race condition on the package.json file inside electron\www (Different to the root project package.json).
While steps are listed below, i also have a repo with the issue: https://github.com/Serivy/cordova-electron-plugin-issue
Work around
I have a work around which is to add a hook before the plugin is installed to create an empty package.json file {} which the plugin install then populates, followed by the main meta data.
config.xml
<hook src="before_plugin_install.js" type="before_plugin_install" />
before_plugin_install.js
const fs = require('fs');
const path = require('path');
module.exports = async function(context) {
if (context.opts.cordova.platforms.indexOf('electron') >= 0 && context.opts.cordova.plugins.indexOf('cordova-plugin-device') >= 0) {
const electronPackage = path.resolve("./platforms/electron/www/package.json");
const electronFolder = path.dirname(electronPackage);
try {
fs.statSync(electronFolder);
} catch (e) {
fs.mkdirSync(electronFolder, { recursive: true });
}
try {
let stat = fs.statSync(electronPackage);
} catch (e) {
fs.writeFileSync(electronPackage, "{}");
}
}
}
Command or Code
Create the app and add plugin
npx cordova create myApp org.apache.cordova.myApp myApp
cd myapp
npm install cordova --save-dev
npx cordova plugin add cordova-plugin-device
npx cordova platform add electron
Reset like it would get it from source control in the .gitignore
npx rimraf ./plugins && npx rimraf ./platforms
Prepare the platform like in build servers
npx cordova prepare electron
Environment, Platform, Device
Cordova electron application with electron plugin (eg: cordova-plugin-device )
I saw a similar comment here https://github.com/apache/cordova-electron/issues/211#issuecomment-959557922 but its on a separate kind of issue..
