Thanks for the report. What kind of toast notifications do you need ? Is it in-app, when the app is running, or as a push notification ?

peternary commented 3 years ago

We're specifically looking for support for being able to call,

ToastNotificationManager.CreateToastNotifier().Show(toastNotification);

Thanks.

Note for contributors

The W3C notifications API may be of interest to build this feature: https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API/Using_the_Notifications_API

MDN Web Docs
Using the Notifications API
The Notifications API lets a web page or app send notifications that are displayed outside the page at the system level; this lets web apps send information to a user even if the application is idle or in the background. This article looks at the basics of using this API in your own apps.

I think such PR (WASM ToastNotificationManager.CreateToastNotifier().Show(toastNotification) would be very hard to merge. Exactly this for Android waits since February :)
