If you are a beginner that wants to learn javascript and react native, or and advanced javascript developer that wants to get into mobile development using react native then this Livestream is for you. This is a perfect opportunity to follow along and build this application together with us, and add it to your portfolio as it will help you land your next job. If you finish the app, tag me on social media and I will give you feedback.
We will start building the Whatsapp clone from scratch, starting from setting up a React Native project using Expo and finishing with connecting the application with a GraphQL backend using AWS Amplify. We will walk through designing the UI layout of the app, structuring everything in components, and putting everything together. We will also implement navigation between screens, header bars, and tab bars for the Whatsapp menu.
For the backend, we will be using AWS Amplify, which is an amazing combination of tools and services from AWS, that helps us build mobile and web applications faster. It offers pre-made authentication components and flows, database, API (REST and GraphQL), storage, and much more. We will be using Graphql subscriptions for the realtime chat functionalities
Doing the Whatsapp clone yourself is a great opportunity to practice React Native, modern Javascript, Typescript, AWS Amplify. We are always trying to use the latest technologies and best practices, so that's another opportunity to learn something new, being it functional components, hooks, state, navigations or AWS and Amplify.
Tag me on social media when you finish the Whatsapp Clone, and I will give you feedback on your code.

@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! 🙏

[@briannezhad1804]

You can push messages to begining of array: setMessages(messages => ([newMessageFromSubscription, ...messages])) @ 1:30:52

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?

[@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.

great content after watch this i am very excited to see more videos on your channel. I have a question that when we configure amplify we give aws IAM credentials. so where is credentials are saved and if in future i build my application then these are go with build or not please tell me.....

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

[@alaabashiyi3346]

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

[@notjustdev]

Awesome bro, keep building

[@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.

[@lcd11001]

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

Hey @Vadim may I get some help ? When I implement subscription method with ".subscribe() " (1hour10min) I receive an error which is just "unknow". Even with a try catch I receive this error. I'm not able to fix taht, can you or someone help me ? Btw thanks for your tutorials, it's awesome !!!

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?

[@richpo9814]

Is it possible or you to do a Snapchat clone? I just subscribed.

[@Nikitosss91]

Thats cool, but can you show how take apk file for android, and also how to deploy app to market
