Should you use Expo for React Native in 2023? 🤔 React Native CLI vs Expo

[@shirakuyanai4095]

Speaking from experience, if you're just starting out or you don't do mobile that much or only do small projects, use Expo. It's far easier to build and package apps with and you don't have to deal with setting up environment because it is a pain in the butt. But if you plan on going long term, use Rn CLI because it gives you more control over the codebase. Also, you kinda don't need the internet to code and build the app which is nice. But you have to setup the environment and need a Mac if you want to develop for Apple's OS's like iOS or MacOS.

[@grimm_gen]

currently building with Expo and I like it!

[@ychinamale]

I'd say that if you are new to React Native, ALWAYS start with the React Native CLI or Expo bare workflow. It isn't as difficult or as time-consuming as people make it out to be. Expo is great but as a React Native developer you don't want your first encounter with the bare workflow to be when you're forced to eject from Expo. That's always my advice to anyone new to React Native. More experienced devs can make that call based on the project requirements. Besides, some parts of Expo can be used by a React Native CLI app, so you don't always have to go all in with Expo.

[@galaxies_dev]

You don't use "eject" with Expo anymore, only prebuild. And the experience of that (if you have to use it) is completely different than what eject used to be.

[@QuickTuts]

It is completely different now.

[@JG-mz7hg]

@@QuickTuts But it's still additional level of abstraction. If anything goes wrong, good luck if you are new to the whole React Native world. If you can, start from the bottom and go up.

What about performance, security, privacy, legal/licensing, scaling up, privacy/compliance, speed, maintenance, etc? For larger projects, those are the type of things which are more important to many, compared to ease of the dev env setup.

[@galaxies_dev]

I am not part of Expo so I can't speak for their privacy, but I assume you should then only do local builds and not use EAS if you fear problems. However, for enterprise questions you should reach out to their support!

[@aurielklasovsky1435]

Thank you for the question, Unbelievable that it was not mentioned. Expo go costs money if you are: updating your app, work with a team (it's a big one), perform more then x builds a month, etc. There probably is a case when you could use it for free but you will then pay for scale.

[@bloggerklik]

I am developing with CLI. Have you moved on to Expo? If so, I would like to know your experiences and answers to your questions.

[@aurielklasovsky1435]

@@bloggerklik I actually just started with react a month ago because I'm a full stack web developer and though it would be the fastest way to release some mobile apps. I am using expo because my goal is speed, but I honestly don't know how anything else works.

[@samuelscheit]

Nice summary, I personally use the react-native bare workflow, because there are much more libraries available. Regarding capacitorjs/cordova I tried a few years ago and quite enjoyed it, but the performance and UX of a bundled web app is significantly worse than (react) native apps. Especially navigation gestures and animations.

[@galaxies_dev]

Thanks Samuel, tried my best to compile all information into this one! I think Capacitor has grown a lot over the last years, so your experience from some years ago might be totally different today - at least that's what most report. But if you still see the differences, I'd love to see an example of that with Capacitor/RN!

[@Itanda]

the expo testing app on playstore keeps crushing, how do i fix that

[@cairtenE]

i have been using react-native since the beginning and tried expo many times in the past, everytime it was a nightmare. BUT, i got to say, i recently started another RN project with the last Expo SDK, and it was a blast, most of the annoying stuff has been solved and the experience is worth it, at least for building a fast prototype. I still have no idea how this translate to production.

[@galaxies_dev]

At this point, Expo is the recommended framework for React Native!

[@AliMukhtar53]

would you recommend to use expo for building MVP of a app like Uber like functionalities?

[@louddude]

so I tried expo with their tutorial, it started falling apart quite quickly, I made it to the final step where they do screenshot but it didn't work on iOS and when I was trying to fix it I got all kind of issues with versions mismatching everywhere. from build erroring because of global expo-cli installed and at the same time requiring it, typescript errors, reanimate errors on ios only etc. quite weird experience actually

[@destroreact5706]

Same issue. The photo stuff also didn't work on IOS. Took a lot of time to solve that

[@ucheiam]

I really would recommend starting with the bare workflow! I really wish someone had told me that. Ripping out expo is not simple and I had to create a totally new app, and walk along its code side by side to correctly change my app to work without expo You’re a dev, it’s not going to be nearly as complicated as you think to use the RN bare workflow.

[@galaxies_dev]

I don't think removing Expo is that hard anymore - the experience is not like eject in the past. Plus, you can actually simply use the prebuild now!

[@AliciaSykes]

@@galaxies_dev Is a prebuild project totally free of all expo dependencies? Is it as neat and performant as a project built from scratch or with the RN CLI tool?

I am a total newbie into programming, but I am building an app, and started with expo but it started to give me random error with the firebase storage library, so I changed to bare react native project, and that shit has been nightmarish, errors everywhere, now stuck in a error with firebase app (not even the storage, just the firebase base). It crashes and I dont any fucking idea why it is happening, and I tried almost everything in the web, and even asked chat GPT lol Might swich to expo again because probably my problem there with storage will be easier to solve.

The problem was most likely that Firebase SDK is at v10 now, and most content was about 9 or below. For example, you don't need to import a special persistence package for React Native anymore!

Hi Simon, I was wondering about the new architecture. Does Expo support the new architecture of RN. I have looked here and there but I am not sure 100%.

[@jfbaro2]

It does. New versions of Expo are always released with the latest stable RN,

[@williamprada9805]

As long as I know, it doesn't because I read somewhere they do not want to write C++ code to make most of their components compatible with the new renderer. And if you go and read RN Docs, they say that expo does not support the new architecture. But I believe eventually they will have to catch up.

[@rede_neural]

It seems like changes I made in styles.xml are completely ignored by expo. This makes it unusable to me, since I can't disable the force dark mode feature of xiaomi devices, which changes all colors of my app. I can't even make a white button, and animating colors have a completely weird effect, because it changes the color abruptly after a certain threshold

Hi Simon, if you don't know React but want to learn React Native. Am I required to learn React first? Or Can I simple jump into React Native? I just want to make cross platform mobile apps with React Native, thanks Simon.

[@truthiz2805]

You can jump into react native directly, they are essentially the same. Work with functional components and do not go into class component for an easier approach that is also very similar to react.

[@DevlogBill]

@@truthiz2805 Thanks truthiz, I asked because when I went on Udemy or watched a KZbinr explain the requirement is React before React Native. I had a feeling there was more than one way to learn something. I did some reading online for some requirements with React. I am assuming you should learn all the hooks? Hooks like the useState, useEffect? Are there other hooks I should consider if I am making a basic crud app? First project will be a simple todo mobile app. Thanks for sharing truthiz.

[@galaxies_dev]

Yes you can! I know many how simply jumped straight into RN, so don't listen to gatekeepers and just get started and learn React as required on the go :)

Issue. I was following Expo tutorial under Learn section. I came across the Gesture.Tap, and the Expo Go app suddenly closes without any error logs. But the gesture works well on android/ios SIMULATORS and web. But not on the Expo Go App. Anyone encounter this same issue? How to resolve it

[@galaxies_dev]

Hmm maybe they have their own gesture handling for the app. I'm a big fan of prebuild anyway!

[@skyzane2735]

@@galaxies_dev I found out the issue. When you first open the app and allowed permissions, it would work. But in your device and when you manually change the settings back to disallow permissions, then either your ProjApp and/or Expo app won’t ask the same permissions again, and it would just suddenly close when trying to access those. The workaround solution to resolve this is we have to manually turn off all permissions again in Expo, basically from zero and rescanning the QR code again. So it will ask permissions for the first time again.

Hi Simon, I wanted to say, thank you for making this video! This is the first video on your channel I've seen (just subbed!) and I was hoping you could help answer this question for me: I've always used Windows my entire life, and I only own windows machines. I've NEVER liked Mac OSX, and I've always found it INFURIATING to use and I've sworn up and down I'd never own one. However, back in 2020-2021 I was looking into react native trying to develop an app and it seemed quite frankly impossible to use Windows for it and that I had to get a Mac. Here in May 2023, what is the process like for coding using Expo on React Native with windows? Is it possible? If I didn't want to get a Mac but rather dual boot with Linux on my windows machine, how does Linux compare with OSX? If I can do it on windows that would be great (I'm using Windows 10, but with Windows 11 being able to run android apps does that change anything?). Thank you again Simon for your videos and your time!

[@galaxies_dev]

Glad you liked the video and thanks for subscribing! So I haven't used Linux and I am actually the opposite, as I did not have a Windows machine for years :D But you should have no problem developing RN apps on Windows in general as you can use Android Studio (or simply Expo) and run the app with Expo Go - same btw for iOS devices! However, you can't create a prebuild with Expo for iOS on Windows, nor could you actually build an iOS app with Xcode from Windows, and I don't think it works from Linux either. In my opinion, get a cheap Mac Mini if you are serious about building apps and want the best tools for iOS as well. EAS is great, but in my opinion there are always cases where you need faster, local solutions for testing/debugging that you lack with Windows. Hope this helps :)
