@@notjustdev Bro, I thought you spoke Russian. You have a Russian name and surname =)
Your site has no problem. I just wanted to say that your courses can be sold. Because they are really useful. But when I went to your site, I did not find the buy button there =)
@@trustcode234 I do speak russian, but it's not my native language. Thanks for your feedback
Hi! Thanks for this playlist! Are you thinking of doing the same thing again, but with Signal's new bookseller? Thanks in advance for your reply!

Hello, i just want to know whether you use signal protocol api in your project ?
I read somewhere that amplify datastore does not implement a search feature. People that enabled search on their project got expensive bills > $75 per month. Any alternative?
At 2:53:50 you claim that the encryption and app works. However, the app is sending an empty checkmark as a message. ANd from the receiving end you are receiving an empty blue bubble. I don't think this should be the case. Could you elaborate more on this topic?
Hi, can it have notification like whatsapp or signal itself.
I mean that if app is closed and someone message me, a pop-up notification comes stating i have a new notification
Please make a video on algorithm
How to create a algorithm using AWS
I want to create a video chat app for my kids and let them talk to each other. Some of them android tablets and some of them iPad tablets. Can you help with that with another video? Thanks!
bro with new update you can't use @connection or @key it has been replaced
Make video to upload a react native app to play store plsss...
When i add publicKey and ForUser on data model, the deploy fail
I receive this message "InvalidDirectiveError: User and Message cannot refer to each other via "
how to fix this?
@Dhanvi Modi yo did you find a workaround ?
still looking for a workaround for this =(
**edit** : I just noticed, later in the video he removes the relationship entirely and uses just a simple ID field on the Message model. So there's no need to make a connection in the db.
how about the video and call feature
We have done that in a separate video: ruclips.net/video/jDTzKrwcDvQ/видео.html
Hello, i followed your tutorial and implemented encryption well in my project. But decrypt is always giving me Unexpected type, use Uint8Array.
The error is on stringToUint8Array(userData.publicKey.toString())
const sharedKey = box.before(
stringToUint8Array(userData.publicKey.toString()),
secretKey
);
console.log("sharedKey", sharedKey);
for (const message of messageList) {
if (message.hasOwnProperty("text")) {
// decrypt message
const m = message.text;
message.text = decrypt(sharedKey, { m });
}
}
Tried a lot of things to get it fixed without luck.
Any suggestions?
By the way -> you have done a great work :)
