Thanks for this! While your setup wasn't exactly what I was using - it was all of the right pieces that I needed to set up to get push notifications working for my business. THANKS!
Great tutorial, thx for the video ! On firefox as you had ignored the first prompt he didn't ask you again. At place of pop again firefox shake a message icon on right of lock icon in url bar ;-)
Hi thank you for this great tutorial. I was just wondering if there is a way insert the notification message on the web page directly, for instance, writing the notification content in a block of the client webpage ?
Hi Chadi, you probably could, but we'll be on a different thread when receiving the message, so would need to post it to the page, which it turn might not even be open.. I would think if looking to show something on the page then a tech like SignalR might be better. Good q though thanks :-)
@@Ashotofcode I see thank you for your answer ! I actually figured about « Service Worker » technology that is used and opened by the navigator on a different thread. The service workers listen to any notifications and forward this notification to the navigator
6:30 you directly passed the public key into the applicationServerKey but I saw others pass it through a urlBase64ToUint8Array function what is the difference?
Hiya - I think maybe as I just pasted it in it worked ok - but to actually pass it back from the client to server in real world scenario it might need encoding. Been a while since looked at this though afraid. Cheers Mark
But will this work if you then close the browser? How open does the "app" have to be? If I have a PWA, in the background on Android or iOS, will it pop up?
Hiya, it will work with the browser closed, as long as you have it running in the service tray on windows, which Chrome will do by default. On mobile it should always be running in the background. Cheers Mark
Is it possible to shedule the Push notifications? So a user can choose on the website a date and on this date he should get a Push notification like a todolist reminder.
Hiya - possible I think yes - you'd need to store the schedule alongside the push details via an API call when the user enabled notifications, then push to just this user at that time. Sounds good :-)
@@Ashotofcode Hey, but how would this work exactly I do not find much in the internet. I already send the selected date in the push message, but now I don't know how to display it on this date, it always shows directly the push.
Is it possible to show me that quick because i think it is not difficult but i do not find something simillar in the internet and my knowhow about that is not very good. Thank you :)
Can this be used in a web chat application to notify the client that a new message was waiting to be retrieved? Currently my chat clients has to constantly pool the server for new messages but this uses up a lot of resources. I would like to have the server send a push to the clients each time there is a new message... that way the client will run the query only when there is a message waiting for it at the server. Thank you.
hiya - yes no need to have the app open. As long as the browser itself is running (and it does in the background these days, at least Chrome, Edge do as I 'm aware) then the notification will appear.
Hi Rhys, good spot thanks yes! just tried again in Firefox nightly and it does a little animation on the url icon, and then you need to click it yourself in order to display the 'allow/deny' dialog box. Looks like this is the way they are going in order to reduce the annoyance that some of these requests can have. I'll try to do a part 2 with the API and database implemented I reckon yep. Cheers
Hi HArris, unfortunately not, we need something running in the background to receive the message and that is the service worker, otherwise you always need to have the webpage open. Cheers Mark
Lost me on step 1, so I couldn't follow along with anything else. 'npm' is not recognized as an internal or external command, operable program or batch file.

Hi Mark, 'Visual Studio Code' is the editor here, and super nice it is :-) some of the auto completion is using this extension [Visual Studio IntelliCode] it learns from what you've typed, and as that was at least the 4th take on the video it had some good data! so might not be as good for initial completions on new code. Thanks for watching by the way, hope it was useful.

@16:40 In Firefox... you can see the "lock" jumping around on the URL.... it wants you to click on the lock to bring up a dialog which will allow you to enable notifications for Firefox. This happens in Chrome sometimes also. It depends on what your default security settings are set for the browser.
