💬 Join the notJust Development gang and let's build together:

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.

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

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!

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

[bestelectrocity]

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

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?

[ushermed]

[ashwanipanchal]

Thank you so much 🥰

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

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

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!

Is there an updated graphql schema for this one?
