Implementing in-app purchase in an Electron app for the Mac App Store

Question

I've looked around and it seems like several people are having this issue but no-one seems to have solved it:

Adding Apple in-app purchase to Electron HTML/JS app

https://github.com/electron/electron/issues/3745

https://discuss.atom.io/t/osx-in-app-purchases-in-electron/22885

Some people suggest using this Node to Objective-C bridge to do it:

Other people suggest using this in-app library, but from what I can see, it only validates receipts:

Has anyone actually managed to implement in-app purchases in an Electron app for the Mac App Store?

How did you do it?

If no one has done it, is it simply impossible to do?

Answer 1

Update

Finally, I added in-app purchase directly to Electron.

See https://electronjs.org/docs/tutorial/in-app-purchases

First solution

I have implemented this solution and it works in development (not yet tested in production).

1. Create a MacOS application (InAppPurchase) with Xcode that performs the in-app purchase (see https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/StoreKitGuide/Introduction.html)
2. Put the InAppPurchase.app somewhere in your Electron app folder
3. Use require('electron').shell.openItem or require('child_process').spawn('./InAppPurchase.app/Contents/MacOS/InAppPurchase'); in your Electron app to start the in-app purchase.

This is definitely not a clean solution but it seems to work...

Second solution

I think that it can also be done with NodObjC. However, this lib is very heavy compared to the first solution.

Third solution

Adding in-app purchase directly to Electron.

I will keep you informed if I can release my Electron app on the Mac Apple Store with IAP or if I found another solution.
