.NET 6 Blazor 🔥 Chat with SignalR using WebSockets

[@saadbilal9519]

Great video. Can you make another more in-depth video on SignalR with authorization implemented? In this way you can send messages to a particular client. It would be great if you could implement the group feature as well. Thanks

[@oveskhan687]

This is amazing, Please also create video on how to debug Blazor app and WebAPI

[@MarcusRedmann]

Great Tutorial. Now i can start my own work with SignalR

[@PatrickGod]

Go for it! Happy to help. 😊

[@labebe2197]

Great video Patrick! Thank you so much!

Good video we looking forward to more videos on signalR 👍

[@PatrickGod]

Alright! Thanks for your feedback! 😊

[@muralikrishnachowdarypolin5601]

Hi how to send messages to single user we just mentioned user ID in hub class or we can do anything in client side if u have any tutorials or any blog please refer to me

[@nove1398]

Great starting point for signalr👍

[@PatrickGod]

Thank you! 😊

Hi Patrick, a few years ago I made a Line of business app for an insurance company in Sweden where I used SignalR together with knockoutJs to disable buttons for saving while one of the workers already had started with the claims process. It would be very nice and useful to see something similar with Blazor, where a clickevent "Start to process customer" or something will make it so everyone else that open that customer will have that button disabled until the "Save changes" button is clicked by the first user. :) I like this pro active way of not letting users overwrite their individual data changes, compared to Optimistic concurrency failure when the second change arrive towards db with wrong eTag (CosmosDb). An alterative way would be to push the changes from first user, towards all users that have the same object in their browser so it pushes changes but I don't like that solution as much. :)

[@PatrickGod]

Hey Jonas, Interesting! Maybe I could build a small EditForm with Blazor and add two users using this form to a SignalR Hub and disable the button for the user that opened the form second? Or I display a list of entries (superheroes, for instance😅) and disable the "edit" button as soon as another user is currently on the edit form of this entry. Maybe that would work. How would you call such a tutorial? Can't think of a great title for now. 😉 Thanks for sharing! Take care, Patrick

[@jonasgranlund4427]

@@PatrickGod Hey Patrick, either of your suggestions would be absolutely awesome. Good question regarding name, functionality wise it is locking form for concurrent edit, but a good name for a tutorial I'm not sure of :( , but the functionality is very nice, especially in a distributed system where there is eventual consistency and 2 different users can overwrite each others changes in worst case.

[@fadidib8516]

what luck i wanted to search for videos about web assembly using signalR. thanks alot!

[@PatrickGod]

Glad I could help! Thanks for your feedback. 😊

[@enmingwang6332]

Nice, great tutorial!👍

[@PatrickGod]

Thank you! Cheers!

[@Saveaaa]

thanks for the example. is it possible to notify clients about new data using minimal api?

[@PatrickGod]

Hey there! As far as I know, SignalR (WebSockets) and a Minimal API are two different concepts. If you would want to use a Minimal API project, you can totally do so and also add a SignalR Hub to inform all the connected clients about new data. And then you could either send the new data via WebSockets to the clients or they would have to click on a refresh button, for instance, to get the new data. Hope this helps! Take care, Patrick

[@furious385]

Cool Content I like it .

[@jonathanloth9128]

Great!!! Best regards from Brasil

[@PatrickGod]

Thank you so much! 😊

[@muralikrishnachowdarypolin5601]

hi please provide any documentation about sending real time messages to user to user i refer so many documents but all are shown same examples like clients.all.send if suppose I tried clients.User(userid).send but how to implement for client to catch single user messages

[@DanielTames]

Excelent video man! I really appreciate all your work!

[@PatrickGod]

Thank you so much! 😊

[@rivaldovola9896]

love you videos. how about a blazor push nofication app?

[@PatrickGod]

Thank you! Great idea! Added it to my bucket list. 😊

[@ricksanchez207]

how does running the server, that executes the program.cs on that project, actually loads the client application and renders the blazor wasm? sorry im confused :D Great Vid BTW!

[@Phantom1037]

Great tutorial! Thank you!!

[@PatrickGod]

Glad I could help. Thanks a lot for your feedback! 😊

Great!!❤

[@PatrickGod]

Thank you very much! 😊

[@hastifallah73]

Thanksss😍

Glad I could help! Thanks for your feedback! 😊

[@efexzium]

Can Blazor web assembly have a signal IR hub and communicate to other clients running the app so it’s decentralized?

[@exception_]

Hello, can you tell me to develop a messenger like a telegram, it's better to use SignalR or regular web sockets?

[@JamesHarcourt]

Good video. Dankeshoen Bitteshoen.

[@張玉書-v7n]

nice

[@rivaldovola9896]

Hey Pat!! how are you? Question i'm want to build a email api service. where a app sends the body, to, from ect info to the mail api and sends the mail. now where i'm having issues is: I want to send a JWT token to make sure the user is authorized to send a mail. lets say I have the token how can I authorize the user? there should be a authentication header to send via httpclient but it doesnt seem to work or i'm not doing it right. idk if ur willing to help i'm just shooting my shot here lol. BTW fan from Suriname, South America

[@PatrickGod]

Hey Rivaldo, Thanks, I'm great! How are you? 😉Maybe my "JSON Web Tokens" (kzbin.info/www/bejne/rGjUZKN7gJZ4d5I) and ".NET 6 Authorization" (kzbin.info/www/bejne/inW8kHeqiaqem9U) video is something for you among others. Hope this helps! Take care, Patrick

HubConnection StartAsync() not useful in pattern(error 405), url maybe what to modification

[@陈志成-y1w]

Http is ok but https is defeated

[@souravsingha3340]

Build chat with database and identity framework.

[@comroec]

how to do a private chat? pls

[@PatrickGod]

Please checkout "Groups" for that. This is the best way to open private chat rooms.

[@unkn0wnrge189]

I thought God was your nickname since you say jesus all the time, but I see your mom gave u birthname god, amazing, at least in name you are in heavens.

[@JakubSK]

Dude you’re the only person using Blazor😂

[@StandStillRushing]

Re-visit this comment in 5 years. Blazor is going to take over and be the most widely used app development framework, I promise. =]
