Similar to the API provided by https://github.com/Polidea/react-native-ble-plx I work on a bluetooth connected medical device and have been using that library to do most of the bluetooth stuff. However, you must detach the expo app to get it working and the setup is non-trivial. It would be nice to have a bluetooth API built into the expo SDK.
We need a module for making WebRTC based video calls from Expo based apps. Currently all packages available for React Native use native modules and require to be linked, for example this - https://github.com/oney/react-native-webrtc
In App Purchases
Moved from: https://github.com/expo/expo/issues/11 Add support for in app purchases to standalone apps on iOS and Android in the managed workflow Status as of July 21, 2020: The same as the previous status update applies here. We are still building the infrastructure that we need to be able to support IAPs in the managed workflow. If you need them, I recommend ejecting to the bare workflow. You can continue to use all of the Expo SDK packages after ejecting, including OTA updates and Notifications. https://docs.expo.io/workflow/customizing/ ------------------------------ Status as of April 14, 2020: IAP APIs in the managed workflow will not be available until we have completed support for native plugins in the managed workflow, which is part of our rewrite of the build service. You may want to consider using bare workflow for now! You can continue to use Updates and Notifications in bare React Native apps now as of SDK 37: https://blog.expo.io/expo-sdk-37-is-now-available-dd5770f066a6 . ------------------------------ Status as of November 7, 2019: This feature is definitely important for us in the medium to long-term but we need to build some more infrastructure before it's possible. We're currently rewriting our build service to make it capable of handling adding In-App Purchase support to apps but it's not there yet.
Integrating Flipper would really help in debugging apps. Flipper is now baked into RN v0.62. Let's get this bad boy into the next expo SDK!
Please add https://github.com/DylanVann/react-native-fast-image for fast image scrolling
Reducing App Size
it will be great if there will be any options to help reducing app size because just simple app size take 24Mb and thats a lot
Support for Realm
It would be great to have out of the box support for realm database. link: https://realm.io/
Is this something Expo could ever do? Like be able to integrate with the iOS widgets screen?
Support react-native-reanimated v2.0
