@Vadim just stumbled upon your channel this past week and want to give you some major credit! Ive been a developer for well over 20+ years and your live coding content is some of the best training content I have come across on youtube. Well done sir! Greatly appreciate all your work and effort! Very organized and efficient and not to mention your IDE of choice is WebStorm just like myself 🔥Keep it up brother, I look forward to all your new content!

[@notjustdev]

Hey @Zeedub, you made my day! Thanks for the kind words. This kind of messages make all the invested time and resources worth it and motivate me to never stop doing this. Thank you! 🙏

In the end, with the problem with useEffect, the thing that can make it work is to put [messages] in the dependence array of UseEffect.

Hello, my graphql doesn't require not null for lastMessageID. I can use ID without exclamation mark (47:38). Is it belongs to AWS amplify api version?

[@odoohub5010]

Hi vadim, i appreciate your effort in training us, but i have a question for you. from 1:18:21 on the video (kzbin.info/www/bejne/i6LCp56Le9OlqdU). if we receive new notification about a new message, when any message is created, even when messages are created in a different room. Don't you think this may become a performance issue, when millions of people in different chatrooms are creating new messages? Dont you think that the millions of users will be receiving all the createdmessages that they dont need ,which needs to be ignored on their device, but can affect their device perfomance or slow the app on their devices? Is there no way to only subscribe for messages that belongs to a particular chatroom?

[@lcd11001]

Can you delete multiple chat rooms with condition like : ID not equal "abc" ? (52:23)

[@alirazzaq1541]

Vadim, the problem in updating the messages.. You setted setMessage([newMessage, ..messages]). This is setting the state instead of updating it. The right way to update the state is setMessage(messages => [newMessage , ...messages]). Or may b setMessage(x => [newMessage , ...x]). Basically x it the prevwous state.

[@notjustdev]

Yeah, that makes sense. Did you try it in this context?

[@alirazzaq1541]

And I forgot to tell you.. I love you man. You are the best.

Hello vadim can you suggest me how can i rearrange ChatListItem depend on last message.....

[@explorerthaj1348]

Hello Brother, thank you for this wonderful video. How can i get updated schema for graphql? older version doesn't support.

[@sebastianwilliams8139]

Great tutorial! Is there a way we can prevent creating multiple chatrooms with the same user? It looks like every time we click on the same user it is creating multiple chatrooms as well.

[@shubhamsood589]

Hello sir. How to add video call functionality in this?

[@amanguptadev]

[@Ibrahim-fh6kv]

Can you please continue with Instagram clone.

[@rob4fu17]

Hello Vadim, while following your guide in the Chatroom subscrption, it works without the useEffect subscription function, it shows instantly on the other user. and when i add the subscription function it also works but it refreshes the chatroom screen, its a bit weird, what do you think ?

[@alaabashiyi3346]

its fixed now. XD but thanks a lot i really love your tutorials and all your projects on my ToDolist
