Realtime Chat App in React Native and AWS (Backend) 🔴

[@isanioka]

This lesson is harder than first video, but it still very interesting! Thank you!

[@notjustdev]

Thanks

hello, I am Mr. Sonam I'm a newcomer to your channel. and happy to be part of this group

[@notjustdev]

Thanks and welcome!

[@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!

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

Most of plugins are deprecated ! A bit difficult to follow,but still an extremly good quality content :) Strongly recommand this video to every fresh React dev

[@notjustdev]

Everything moves so fast in our industry that a lot of the plugins have been updated/deprecated from that time. Check out some of the newest builds

it's almost weekend wonder which new tutorial is coming :)

[@devsmith948]

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

[@notjustdev]

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

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'

[@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.

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

[@MangoFlamingo]

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

[@FaisalKhan-ce2qu]

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

[@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 😄

[@siddhi.classes.jalgaon6685]

Unable to resolve "./aws-exports" from "App.tsx" I am facing this issue please help

[@sdljfgsdfg]

I currently fixed this issue for myself. I am in VSCODE you need to rename src/aws-exports.js to src/aws-export.ts. then go into the .gitignore and change it to .ts there too. here is a post on github github.com/aws-amplify/amplify-js/issues/222

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

[@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?

[@shodeolumide2140]

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

[@notjustdev]

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

[@notjustdev]

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

[@TopAfghanMusic01]

[@dilan3159]

Cool! Could use something like easybase.io too

[@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.

error coming on UserChatRoom Failed to retrieve 35 record(s) 9 failed with the error: Field user cannot be set to null since its a required field. 35 failed with the error: Field chatRoom cannot be set to null since its a required field. What to do?

[@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!

[@creative-commons-videos]

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)

[@siddharthanelango6034]

kindly help me bro, did expo supports video call,if supports can you provide any example for that

[@sebastianwilliams8139]

Is there an updated graphql schema for this one?

[@balaji-venkatraman]

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

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

[@sourabpramanik996]

[@pritam-kunduu]

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. I followed your frontend video with much hope that I would be able to deploy a fully working react - native application. But now all i am left with is a useless mere ui/ux. Not expected.. very disappointed

[@notjustdev]

Sorry to hear that. I am using the technologies that I love and I believe will bring you value in the market. I can recommend you some good tutorials using Firebase. There is a ton out there
