I've added a new blog post which describes how you can do some interesting programming tricks with Object Pascal / EWB.

Btw, did you ever look at the notification frameworks for Android and iOS? Maybe an extension for Nice Components if it's easily done?

I cannot think of what ithe mechanism is called.  I thought they were badges, but that's not right.

That mechanism is called "web push notifications". Here is a description about the stuff you can show on the client:

And here is the doc from Apple:

https://developer.apple.com/documentation/usernotifications/sending_web_push_notifications_in_web_apps_and_browsers

Google does it in a similar way, iirc. There are tons of companies that encapsule the services for you, like pushalert.co, airship and many more.

I developed an app where I want to alert truck drivers that they can enter the premises. Currenty, my EWB app polls every x seconds, and plays a sound + shows a message if needed. That does not work reliably: the driver can close the EWB web page, the smartphone OS can decide that it does not want to play a sound from a webpage when the display is off, even the browser can decide that it kills the timer. None of that can happen with web notifications.

Oh right.  I made some emergency notification systems that alerted thousands of users of security events, and looked at web push as the successor when RFC 8030 was introduced.  But the clients were no longer interested, so I didn't pursue it.

You don't need to subscribe to a service to do this.  There are PHP and Node frameworks on GIThub that can do it from your own servers.  I think Apple, as usually, does it slightly differently, despite there being an RFC for industry standards.... sigh.

I won't be getting to this any time soon, too much work in the pipeline, and not enough interest.

I'll post some code when I implemented it
