At the latest App.js Conference, key updates were announced for React Native and the Expo ecosystem, shaping the future of mobile development. Exciting new features, including Expo Router V2 and CSS support in Native, open up endless possibilities for universal app development. The Expo SDK 49 further expands capabilities with features like auto-typed route names, aliased imports, and both static and async routes.
The introduction of React Native 0.73 offers a more powerful navigation library, enabling deep linking and file-based navigation, alongside editor autocomplete and static file generation. Also, improvements were made in SEO and lazy loading, enhancing web app functionality.
Furthermore, thanks to the team at Microsoft and Meta, React Native is now coming to Windows, MacOS and Linux, giving the possibility to run a React Native application even on a Raspberry Pi!

dear vadim please bring some app tutorial with MERN stack without AWS amplify .

[@ben7226]

That's super excited, it's getting better and better ever time.

[@UsamaThakurr]

Since Expo Router I can't thank them enough because before that I used to be inside Tutorial Purgotory of React Native and Native development now. I just follow this channel and that's it because I love React Native ❤

[@ra-dro]

Thanks very much for such good recap! I also heard there something about Debuggin or Deguggin.

[@andresgutgon]

Awesome recap! It would be nice a video explaining in deep react native new architecture

[@timotiussimanjuntak9148]

[@abhishekjha6102]

Hello vadim! Thanks for the insight. We would love to see the tutorial in the topic of internals and architecture of react native

[@notjustdev]

Thank you for watching! That's great, I will take it into consideration 🚀

[@__diego432__]

Thank you for you content, I want to know more about RN because I´m very interesting and I appreciate the content about the technology because is too scarce on youtube, thanks for that and I hope you continue with this youtube channel, greetings from México!

Great work. Keep it up 👍🏻

[@notjustdev]

Thanks for watching and for your support! 🤘

[@Kevin-jc1fx]

Thank you for this recap, it is very exciting to see React Native grow this. Regarding expo router, is it already mature enough for production? I am building a prototype for a customer using it and some elements seen very hacky or hard to properly implement. I understand the documentation is not yet completed but I am worried that I might encounter a serious roadblock that would force me to start over a project with react navigation because some important feature is not yet implemented of stable in Expo router.

[@tallawahh]

I have this same issue too. Usually leads me to writing different code or component configuratios for each platform. If even the low level expo APIs have issues, what happens when we start using more complex components

[@shohjahonataxanov817]

Thanks a lot

[@tallawahh]

Honestly i love react native for all the reasons you outlined in this video. I do web development (React, express, etc) for the company im employed to but ive been doing react native development for my own personal paid projects. The only technical "issue" (more of something diffucult to grasp for me) is writing native modules for a use case of the app running on a specific platform, and how i can basically create my own react native/expo modules for unique functions i need in my app

[@tallawahh]

That would require me to do more research into C, and the iOS and Android flavours of C, so I can write modules and import them into my react native projects. Writing unique packages for the browser is pretty straight forward, npm, yarn, etc. Writing native modules for react native is that notch on my belt I need so I can create pretty much any progressive app for my clients

[@Kevin-jc1fx]

@@tallawahh I think learning Kotlin and Swift should be enough for most cases were you have to write a fully native functionality. You will also need a good enough understanding of each platform to understand were it should be included. Some people will just hire 2 devs to implement that for each platform, as long as the cost stays reasonable.

[@tallawahh]

@@Kevin-jc1fx lol and I'm trying to do it all myself 😅 thanks for the insight into kotlin and swift tho, that's where I'm gonna start tbh

After finding out about PWA's I just been focused on them. Such a great thing with no middleman involved in ur app. I only work with the react boiler plate offered. I know expo has a pwa feature but no clue how to work it. Would be cool if u made a tutorial on it. Thanks!

And can you tell which to use expo or cli and when to use ?

With all the recent improvements and innovations in Expo CLI, going with it is a no-brainer 😄

if you want freedom use cli

[@worldonwheels9371]

This all sounds great, but what I hate the most about using react native is the primitive form of debugging compared to working with true native languages in Xcode and Android Studio. I know there are extensions to set breakpoints in VSCode and have a similar experience to the native IDE’s, but in my experience it’s always incredibly buggy, slow and frustrating.

[@notjustdev]

At app.js, they also covered the future of React Native debugging. So even though at the moment, one of the biggest pain points of React Native is debugging, they're working on that and making it waaay better 😁 Check out the talk about it here: kzbin.info/www/bejne/qYOvpqGNet-qfqs

[@worldonwheels9371]

@@notjustdev thanks for the link, I’ll make sure to check it out! Glad to hear they’re working on it.

Expo or CLI? ...and why?

[@valentineejakpomewhe4352]

does tiktok using react native web?

[@piyushsagarit33avi8]

It all about EXPO ? I think expo is build top of on react native, isn't it ? But the react native documentation is not updating and also not good ?

[@notjustdev]

Yes, that's right! Expo is built on top of React Native. While Expo can be a helpful framework, it's important to note that the React Native documentation is not specific to Expo and may not always cover Expo-specific features or functionalities. However, Expo does have its own documentation that provides guidance on using Expo-specific tools and APIs. At times, it would be a good idea to refer to both the React Native documentation and the Expo documentation.

[@jimmynoujaim4914]

Are these features expo only? Or bare react native too?

[@notjustdev]

@@jimmynoujaim4914 Most of the features are react native in general, but some specific ones, for example related to Expo Router are mostly about expo

[@alifhasanshahOfficial]

The most difficult part of becoming a React Native developer is that most people don't have a Mac. People can't afford Macs, so they use Windows, and there is no iOS simulator free on Windows machines. This is the main problem. Why doesn't a big tech company make an iOS simulator free for Windows?

[@glaze4629]

That's just half of the problem, so far i'm aware you can not even compile the application without a mac

and where is the Linux port ;) there is 0 alive projects for react native on linux

[@gnom-om]

- New arch they are delivering during last 2 years (or more) and still no end. - There are no benefits on Android with new arch (performance ). - DX for RN on Mac and Windows is awful - total lack of documentation and third-party libraries. Why we need CSS and Web in RN if we still have problems on mobile side? Its ridiculous to see here about exciting of the RN future (: Personally i do not see bright future yet. p.s. to spend so much time on flipper integration and now to say that we need to de integrate it. Facepalm...
