Guidence for making mobile app notifications

Hey guys, so i made a wrapper for a website (

artfight-wrapper

artfight-wrapper

) and i want to make a xamarin forms (that's the only platform for mobile i know how to use) and i'm wondering how i could go from having that wrapper to making notifications pop up every time someone messages me for example, the wrapper is on npm, made in typescript

Xamarin is dead, supplanted by MAUI.
But also, what is that wrapper? A website?

yep

ik, but i learned it in school

Unless you have to use Xamarin, I would encourage learning the new stuff.
But since it’s a web site, you could also use web push https://web.dev/explore/notifications

for this i would need to setup an api and do it that way?

Mąż Zuzanny Harmider SzczęścieOP•6/25/25, 7:49 PM

to make it work on mobile id need to expose it to internet and my isp doesnt allow port opening

jcotton42•6/25/25, 7:49 PM

ah, then mobile app it is i guess

Mąż Zuzanny Harmider SzczęścieOP•6/25/25, 7:55 PM

yeah, but how would i go about it?

If you don’t have access to the internet you won’t be able to make a push notification system in real time

BlockedUser•6/26/25, 7:39 AM

If I have understood correctly

Kev•6/26/25, 8:19 AM

im a bit confused by the requirements. how are users messaging you if you dont have internet access?

If you want to use something that looks like a push notification but is local you can look at Local notifications.

im still not sure what the requirements.

How is the website working if there is no internet access?

yep, i setup events already, which listen to changes (like a new message appearing) and it emits an event

Mąż Zuzanny Harmider SzczęścieOP•6/26/25, 8:26 AM

i just dont know how to go from event being emitted from my npm module to it sending a notification to my phone

Kev•6/26/25, 8:28 AM

OK thanks. in that case, assuming you are hooking into these sorts of events

https://developer.mozilla.org/en-US/docs/Web/API/Notifications_API/Using_the_Notifications_API

Id say local notifications are the way forward. these are notifications that show on device the same way that a push notification would show. they are usually used for timed events ( calendar pop ups/reminders ) but I believe you can show notifications immediatly with them too

MDN Web Docs

Using the Notifications API - Web APIs | MDN

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.

If you cant use Maui you will have to hook into the native Android/IOS to trigger them.

Mąż Zuzanny Harmider SzczęścieOP•6/26/25, 8:30 AM

is maui far different than xamarin forms?

Mąż Zuzanny Harmider SzczęścieOP•6/26/25, 8:30 AM

also how would i hook up a npm package to a maui/xamarin forms project?
is it even possible?

Kev•6/26/25, 8:32 AM

Unforunatly im not the best to answer that, I never used Xamarin, I came from Native Android to Maui.

Mąż Zuzanny Harmider SzczęścieOP•6/26/25, 8:33 AM

ok, is it possible to somehow import npm packages to maui?

Kev•6/26/25, 8:40 AM

Its not something ive considered so not sure off hand. there are a number of web options within Maui ( Webview, HybridWebView ) that should allow you to host local html/js ( or just show the website ) but im not familiar enough with npm to answer.

Someone esle might be able to. in the mean time take a look at

https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/hybridwebview?view=net-maui-9.0

https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/webview?view=net-maui-9.0&pivots=devices-maccatalyst

I've used webview and im OK quierying the html/js from c# to get cookies etc. so you might be able to use these.

from what your sending i would need to rewrite the wrapper in c#

Kev•6/26/25, 9:01 AM

if you dont mind going more native you could take a look at this

https://developer.android.com/jetpack/androidx/releases/javascriptengine

I've not looked at this one personally but it should allow you to evaluate JS in native code that might give you a way in to what you need without a rewite. but im not sure if this works with html so might not be a good solution.

Others might know better.

IOS does have a similar system.

Kev•6/26/25, 9:27 AM

One other thing that might be worth looking at, i've not used it myself so this could be very wrong. but maybe take a look at blazer. its used to build websites using c# but it may allow you to inject your package into the webview it uses.
