I have an expo react native project which works perfectly fine on every android device that I have tried.
but when I tried to build a pwa version of the project with expo build:web , the components renders in a totally wrong position and the output is not acceptable at all.
I want to know if anyone has the same problem with expo web builds, and how you manage to fix this problem.
is there any way that I change the implementation of the web application without changing the output of android app?
thank you all.
Did you try to use Platform Specific Code with https://reactnative.dev/docs/platform-specific-code
With your situation, it will be something like this
HeaderBar.js # Webpack, Rollup or any other Web bundler
HeaderBar.native.js # React Native bundler for both Android and iOS (Metro)
HeaderBar.android.js # Android only

I have a react-native App which is not using Expo and runs on android and iOS. Is it possible to make it run on Web? I found multiple projects for this purpose but I am not sure if those projects are aimed to be used only with Expo projects or not. I use multiple android and iOS modules in my app, I can't imagine how those modules will be converted to run on web. Any advise? Is what I am trying to do is even possible?
If you're using native modules with android or IOS specific functionality then you'll have to find a replacement that supports web, (or keep them and use something else for web).
Also no need to stay away from expo modules, expo modules can be used outside of expo too, here's how you can set them up: https://docs.expo.dev/bare/installing-expo-modules/
I'd suggest you listen to some of Fernando Rojo's talks about this:

I am implementing Stripe in my React Native (Expo) app. When testing it out with ExpoGO it works well, and so does the iOS build via Testflight. However, after building the app for Android it will crash whenever the CardFormField component (provided by Stripe) is rendered.
I have logged the errors in Sentry, and this is where it goes wrong:
Binary XML file line #5 in [censored]:layout/stripe_card_form_view: Error inflating class com.google.android.material.card.MaterialCardView
IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).
I then found this, here:
In order to use CardForm component, you need to install and configure Material Components theme in your app.
I do however fail to find information on how I am expected to comply with this requirement using Expo. Do anyone have any ideas?
I am using:
expo 43.0.3
#stripe/stripe-react-native 0.2.2
App is built with eas
I use expo (not an ejected app)
Thanks in advance for any help.
With Expo you have a choice between managed vs. bare workflows. In order to access the build.gradle and styles.xml files to configure the Material Components theme you need to switch to a bare workflow. You need to use expo eject to create the native Android files in question.
Hello so I'm working on an app for android and iOS which is quite developed by now and I'd like to activate react-native-web on it. the problem is that I have a bug when I try to run the script to launch the web development server :
The first error at the top is the one I'm struggling with I've tried updating my babel config :
I tried deleting the babel config at the root of my project and it changed nothing like the babel config has no importance
It is being used though to build the android app i know that, but for the react native web build it seems he has no importance
But is still get the same error again and again
please let me know if you need any more information's on this issue
I have build a project in react-native, for now I am testing the android app by using Expo Client App. I am using Visual Code in Ubuntu 18.04.
So the problem is, now I want to test the project for IOS, but unfortunately i can't test the app, because I don't have MAC OS.
Can anyone tell me the alternative solution of testing react-native project on IOS?
And if somehow there is a solution of creating IPA,then can I use that IPA in IOS without uploading it in AppStore?
You can use snack :
Snack lets you run complete react native project in a web browser,you can set it up on your local machine directly use it from snack.io which also let's you test for android and ios as well
My Expo-based React Native App works without a problem when run in the Expo tool but gave the following errors when built as an APK to be installed and run standalone.
A series of white screens keep flipping before the blue screen comes up.
Here are my App.JSON and Package.JSON files
Package.json
App.json
And here are the screen capturing the error message.
Actually there are two ways to create a React Native application
create-react-native-app (CRNA)
react-native init
As you stated in comment section, You created your project using CRNA
CRNA will gave you some form of solid project structure, which is really useful for beginners to get started with react native, you code the app with pure javascript and the app will work inside Expo.
Now if you want to take build and run as a standalone apk for android,
There are two methods
You can run command: exp publish:android
You can eject your app from expo
Dont use exp publish for standalone apks,
You can use second method:
To eject your app:
First if you dont use any expo apis inside your apps, it is very easy to eject and build as a stand alone apk.
just do yarn eject
This will gave you some instructions and follow that.
After that your CRNA project structure will be converted into react-native init project structure, now you will be able to see "Android" and "iOS" folders inside your application
To take build Run: connect your phone with USB debugging ON and react-native run android.
That's all.
Solved my own problem. The 'eth-lightwallet' library works perfectly within the Expo development tool but when I build into an APK, it just made the white screen turns up with no meaningful error messages.
The solution is to replace it with a pure web3js implementation.
This may be useful if you are developing a mobile app for Ethereum.
