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.

I'm a newcomer to your channel. The content you've been putting out is truly amazing. So helpful while following it along. Kudos

[@bradike1]

Vad this is so great, man. I recently started using Amplify for my serverless backend with RN apps and i'm been checking out graphQL. I was trying to teach myself graphQL based on the AWS example chat app and its not nearly as helpful as this video. Your explanation of the schema and connections will really help others too because its hard to find good graphQL schemas online that really explain or work with AWS appsync. Thanks so much for making this video and keep up the good work!

[@endbringer121]

Great tutorial, Vadim! This is the second that I follow, I am learning much here!

[@notjustdev]

Glad it was helpful!

[@lcd11001]

1:21:18 Can we named the table in format proj_table_name for easier filter / recognize when we developed multiple projects? Or the DynamoDB will auto filter them by project?

[@MangoFlamingo]

Hi Vad! I was wondering if you have a github example that is a AWS react Native/Expo that use microservices?

[@sebastianwilliams8139]

Hey Vad just wondering, how can we be able to run the app per environment? Can we use react-native-config and define there the things needed like the graphql endpoint, region, etc so we can still run the app and choose whether to build it in dev, staging, or prod?

[@junkaihwong8721]

Hi Vadim! Have been watching your content. it's super cool :D I have a qn. i want to add total number of unread messages by user for each chat (group chat too) and i am wondering how to go about doing it. Would appreciate any guidance. thanks :D

[@ashwanipanchal7467]

I love your all videos but i am not able to find your video call app. Can you please share the link of that playlist or video ? Thank you so much 🥰

[@Ibrahim-fh6kv]

Hey bro best react native tutorial on youtube and can you please continue with the Instagram app.

[@CarlosManuelGv]

Hi Vadim, first of all, thank you very much for all of this!!! I have a question, did you know that there is a 100 subscriptions limit using Appsync from every client? A few users on your app would make it crash, because you can't subscribe to conversations. Did you think about it? do you have a solution for this? We are creating a chat service for our app and we just realized this, any suggestions or help would be much appreciated :) thank you very much.

[@WinTunMMOCC]

You have to use graphql via appsync and how to over come limit when the record are growing too many.

[@devsmith948]

Really useful video!!! I have one question. Can I customize SignUp and Signin screen? for example, I want to add more information in siginUp screen.

[@notjustdev]

Yes you can design them on your own, and call the signIn method that you can import from 'aws-amplify'

[@mateonavarrette4864]

Hi Vadim, great tutorials so far. I completed the frontend now I'm starting here on the backend. I had a question. So after I ran amplify api and set that up, I ran amplify push. It was all going well then I got an error. It popped up at 46:28, I never received a GraphQL endpoint: EROFS: read-only file system, mkdir '/graphql' An error occurred during the push operation: EROFS: read-only file system, mkdir '/graphql' I then ran sudo amplify push but then I got a new error: An error occurred during the push operation: EACCES: permission denied, unlink '/Users/mateonavarrette/Desktop/react-native-demo/WhatsAppClone/amplify/#current-cloud-backend/amplify-meta.json' I couldn't figure out how to get rid of these, so I just went to the next step which was amplify console api, and there doesn't seem to be anything wrong - as my screen looks like yours. Is this something I should still be concerned about? If anyone else has any idea too, please let me know. Thanks!

[@mateonavarrette4864]

I see a few minutes later you reference the src directory to access the queries.ts file. Looks like I didn't generate one because of my first error. If anyone has any tips let me know!

[@bestelectrocity]

You're the best Vadim :) , can you make tutorial on Uber Eats with Firebase BackEnd if its possible, I would greatly appreciate :)

[@notjustdev]

Thanks for the suggestion

[@lcd11001]

could you pls share your experience how to make a video call with AWS? Thank you

[@bellomayowa6993]

Hello, thanks so much for this tutorial, but I have a question, is it possible to add online functionality and when a user is typing? looking forward to your answer

[@notjustdev]

It would be possible to do it using state, as you provide a hook for the UI to know when to re-render your component. Give it a google search 😄

[@chakibsalah7287]

Nice contents and a lot of useful infos;It would be helpful if you provide timelines;

[@notjustdev]

Hey, thanks a lot for support. I will take some time and add timestamps to the videos

[@cubedev4838]

Can u make more functonalities like upload image, video

[@sebastianwilliams8139]

Is there an updated graphql schema for this one?

[@balajivenkatraman5271]

Can we detect online/offline status of a user from AWS Appsync. Because i tried to update a field to offline when the user goes offline. But i did not work since when i go offline my API will fail to update

[@maneeshmanorenj6311]

Does it have audio message and notifications

[@Blocker407]

Does the app also have a web interface?

[@shodeolumide2140]

Please what screen recording app did u use to achieve this. Or which can you recommend please?

[@notjustdev]

OBS

[@FaisalKhan-ce2qu]

*Headsup* things really start to turn after 1:38:00 when we work on schema! LOL!

[@ayodeleayoola9644]

Is there no package for parsing form data like it is in react which is formidable? Like uploading the profile picture from the front end into the backend instead of using image dummy data

[@notjustdev]

I could have implemented that, but for the sake of simplicity, I decided to go with dummy data images

[@ayodeleayoola9644]

How do I do that?. Am interested.

[@naumanali8357]

can you please update graphql schema

[@devsmith948]

And I can't see qureries.ts file in src folder. Maybe I made mistake for amplify? Can you explain the reason?

Make sure that when asked "do you want to autogenerate code for amplify queries" you answer yes

Hi Vadim, thanks for this tutorial. I have an error about Aws amplify. Is this service free for using? I am from Afghanistan, we don't have any online banking account. I got an error about subscription, please reply

You need a valid credit card when registering on AWS, though most services on aws have a free tier which is more than enough for testing the app while in development

please help me, i really want to use AWS Amplify for my existing application, it's in laravel now but want to try GraphQL and Amplify, but i don't know how can i implement queues, like in laravel it is super easy to use, My app is kind of Quizzing app where user join a quiz and submit it, and after a while ranking is calculated based on their score, so as soon as user join a quiz I want to notify them when quiz start, also when results are declare i want to notify them also, currently what i am doing is when any quiz is created, i add queues based on expiry, let say current time is 1:00 PM and quiz start at 5:00 PM, when quiz is created i add queue that will trigger on 5:00 PM to notify users to start quiz and also one more queue right after 15 minutes when results are declare

[@notjustdev]

The queues on AWS are implemented in the AWS SQS service, check it out. I integrated the laravel queues system with the SQS. The only downside is that SQS support delayed events for app to 24 hours (if I am not mistaken)

[@ankushjoshi706]

Is the app completed?

Is it possible for a malicious user modify the app to read other people’s messages?

Hello, in ContactListItem the input of newChatRoomData is giving error "variable input has coerced Null value for NonNull tyoe ID!"

[@notjustdev]

That means that you are sending a undefined value to the ID. I can guess that it fails to create a chatRoom, and when you are trying to access the id of the chatRoom it gives undefined. Try to console log the result you receive from creating a new chatRoom

Very very disappointed. You used AWS and I don't have any card so I couldn't complete the sign up process. I wasn't able to follow along the series any longer. You should have used firebase for this.

Not expected.. very disappointed
