I cant believe this video is for free. It's been years since I last had used expo and I recently started working for a start up and we'll be using it again and so much has changed and I was so confused about the build process. This is golden content, thank you!

I had a lot of problems trying to build the application using EAS with Expo 51, lots of graddle errors or different stuff, so i finally got it using the prebuild method and building it later as a standalone app. Thanks!

This was a pretty honest review and tutorial of why to use or not use Expo. Thank you!

Hi Simon, thanks for this great video! I got one question, my team only has Windows machines at work, I know that I can use Expo Go to test the app on our physical devices (iOS and Android), however I’m confused if we actually need Macs to build and deploy our apps to App Store and Play Store. My question is: is there anything I need to manually configure on the native code using xcode and android studio? Things like “Signing and Capabilities”, “Build Settings”, “Bundle Identifier”, etc? My initial plan is to configure the expo prebuild command on my pipeline and use a macOS GitHub hosted runner for building the iOS version, once the app is built we would download the IPA and proceed with the other steps to deploying to the App Store; we already have Apple Developer accounts setup, I’m just concerned if there’s anything we need to manually configure on xcode for Release Version. Thanks in advance!

do you have any basic course on React Native and its pre-requsite. Thanks

[@henriquematias1986]

For some reason when i do run:ios the first time it opens the app on the simulator or phone it crashes with an error. Then i have to delete the “ios” folder and manually run the app. It’s weird, using latest expo based on the “onboarding” process

[@galaxies_dev]

Yeah the current installation is somehow messed up for me as well :/

[@henriquematias1986]

@@galaxies_dev that seems to solve for me tough, deploy one time to device, delete the ios folder then run it on device works.

[@bnv1n]

Hi Simon, great video, thanks! I have an expo project in a monorepo, and i get ERR_FS_FILE_TOO_LARGE error when running npx expo, any idea what does it mean? When taking out the project from the monorepo it works iust fine

[@MugivaraLuffy]

Same question here!!!!!!!!!!!!!!!!

[@Trenythingispossible]

the only issue I have been running into is, when doing the `npx expo prebuild` only gives option for android and not ios?

[@galaxies_dev]

You can only do prebuild for android when you are on windows. You can't build iOS apps on Windows!

[@AtizaJuanita]

What a gem of a video!

[@galaxies_dev]

Thank you mate!

[@jokovBG]

I am still a bit confused. If I want to install the app on my iPhone is there any other way different from using Xcode? The point is to not need Apple developer paid account.

[@galaxies_dev]

You can use Expo Go, but it's very limited. If you want to develop iOS apps, you simply need a developer account

[@erie_e9]

Hi, it's not clear for me. Can I use EAS-CLI + React-native CLI? specially EAS Update, I ask it trying to replace Codepush

[@WebDevJapan]

Awesome! Yeah we had some poblems with an app we built at work using Expo Go and later decided we wanted to put some kind of Google maps or some other map functionality into it. It isn't going well lol

[@prosperdzingo5895]

ooh that's bad did you manage to fix the issue

[@WebDevJapan]

@@prosperdzingo5895 Actually, no. It's just a little side project for us, not ofr a client. None of us have ever built a mobile app through to production. We are all busy with the main project right now. We are also trying to build one with web3 functionality and it's also not going well. I'm not having a fun time with React native when it comes to building more complex apps. Simple stuff is okay.

[@MarlonEnglemam]

what exactly was the issue? I'm curious (perhaps expo go makes it difficult using map related features because it might cause location errors or smth?)

[@anthonycaneke7382]

Thanks so much for this content... So a quick question, after running prebuild to add some code to the android app build.gradle file can you still run: npx expo prebuild --clean? will this remove the feature i added in the build.gradle file?

[@PIYUSH61004]

I am still confused. Should i go for Expo or React Native CLI? Whats trending the the job market?

[@coder415]

currently, react native officially encourages using expo by default. you can check the documentation. i think this is also related to the new architecture.

[@ankushjain358]

Superb detailed video! 👏👏

[@zaidiftikhar2863]

Hi, when I run command npx expo prebuild it's created only android directory nor iOS. How can I create iOS directory?

[@galaxies_dev]

If you are on Windows, you can't create an iOS prebuild.

[@nounjopagnol1299]

Thank you so much for the video. I learned a lot, just one question about eas: do you have to install it first?

[@holdenjack]

Hi Simon, do you know why some Macs don't need to install Watchman and some do? My work Mac doesn't work without Watchman but my personal Mac builds just fine without it.

[@MehmetTopakdev]

Is prebuild convert used expo packages too? I mean after we prebuild and switch to the native, can we use expo router, expo icons etc? Are they free to use after prebuild?

[@galaxies_dev]

Yes, you can use all packages after prebuild and it's free

Hi Simon, I would like to see a video on "How to implement Firebase Analytics in Expo". That would be nice. Keep up the good work 💪

[@galaxies_dev]

Great suggestion!

[@jayphnx]

What I don't understand is the "why" of EAS - vs. using prebuild etc to test locally. AFAIK one can even plug in a device via USB to test locally this way (I haven't done that yet though)

[@galaxies_dev]

Not everyone has a mac, and companies don't want to run builds locally. EAS can handle all of that (and more) in the cloud

[@jayphnx]

@galaxies_dev haha I don't have a Mac. Sounds ike I'll need EAS for eventual iPhone testing then. Cheers 👍😊

[@terjeoseberg990]

I have been developing my app on my laptop and running it on my devices and on friend’s devices using debug mode where all the console log output shows up on my laptop. I now want to create a release candidate that’s uploaded to to my Expo account so that people can test it without involving my laptop. I’m having trouble finding a tutorial that explains how to accomplish this. Have you already created a tutorial for this? Are you willing to create one?

[@withpaulex8645]

Thanks for the xcode part

[@Aethid]

Finding a developer who prefers xcode over android studio must be rarer than spotting a unicorn. Jetbrains IDEs are usually best-in-class for their respective languages. On the other hand, I think the only IDE I have had the displeasure of using that is worse than xcode would be netbeans, and that is taking me back some. A part of that might be coloured by how compiling a large ios project in xcode took an eternity on my macbook. I am talking an hour or more. The same app for android would take a few seconds.
