Got notifications implemented for big two which was rather annoying. Turns out there are two web notifications apis. There is the Notification which you need to use to check if a user has allowed permissions for a notifications on website. However on Android ( possibly IOS too?!) you don’t invoke local notifications with this API (even though you can!) . You have to ensure you have a service registered to your website and you have to invoke a notification using said service workers notification method 🤦. Its horrible ergonomics, but it seems to be working on Android devices… I only realised after reading this PSA that was buried away.
Main limitations of my current local notifications system is that when im in a different game, notifications from another game wont be triggered. I think the more robust method will be to implement push notifications which looks way more involved
