React native expo example app doesn't seem to work
Kulgar opened this issue · 11 comments
Current Behavior
I Tried to run the example app in different ways:
- using the QRCode in my expo client on my device
- using Appetize.io
- downloading the code and running yarn install & expo start to open the app in a simulator
None of these worked... The JS gets bundled within expo, but then I either get a black screen, or a white one and, after a couple of seconds, the device closes expo.
I'm a bit puzzled because I get no errors at all, I don't see anything in the logs nor in expo...
Expected Behavior
- Well, the example app should work, shouldn't it?
How to reproduce
- Trying to launch the example app using one of the ways I described above.
Your Environment
Only relevant regarding the third way I tried (running on a simulator).
| software | version |
|---|---|
| yarn | 1.22.4 |
| expo-cli | 3.24.1 |
Let me know if I can help :-)
I had the same issue with recent releases written in typescript. In my case, (after hours of investigation ;), I found that the root cause of the crashes is because react-native-offline ships a compiled JS version of the lib (dist/react-native-offline.js), which references in some way react-native 0.62.2. However, expo SDK embed different versions (even a 0.61.x for SDK 36), which leads to incompatibilities with react-native-netinfo (in fact this is also the issue described here #252 )
When I set the main entry in package.json to src/index.ts instead of dist/react-native-offline.js, it doesn't crash anymore. However it wouldn't work for non-typescript users.
@colinux Unfortunately I wasn't able to launch the app... What package.json did you change (where)?
Could you share what you did exactly to launch the app?
Thanks a lot :-)
@Kulgar I'm talking about the package.json of this library.
- "main": "dist/react-native-offline.js",
+ "main": "src/index.ts",I'm running a fork with this patch if you want to try it :
- "react-native-offline": "5.7.0",
+ "react-native-offline": "https://github.com/Imparato/react-native-offline#v5.7.0-compat-expo36-1",However this fork contains a few more changes for my app, notably I removed the redux-saga dependency.
@nikolaytsigvintsev : not yet I'll retry tomorrow normally. I'll let you know.

Thanks!
@nikolaytsigvintsev : No luck here... I'm completely stuck...
I did a fork, changed the package.json as colinux did... I had to add react-community/netinfo package.
The project is building but when it reaches 100%, nothing happens, expo is stuck and no pages are ever rendered...
I'm giving up. I hope the maintainer of this package and example app will be able to help us.
@Kulgar : I also tried different installation options, but it didn't help, figured it out without an example.
thank you for answering!
So, it works guys, if you change version of react-native-offline to 5.0.0 in package.json and use npm
