I've created a basic react-native project for example test. I want to use realm to store my data. I've installed realm in my project but I can't use realm without any problem.
Please use realm in a basic project of react-native.

I'm building a React Native App for a Chinese Company. I'm using Expo.
I really would love to use Google Maps, but it is not allowed there...
The best solution I found was to use Baidu Map,
I searched for SDKs and found some of them in GitHub.
I decided to use this one: https://github.com/qiuxiang/react-native-baidumap-sdk
which provides great documentation.
Although, I'm having some trouble implementing it to the app. I think that they don't support expo.
Does anyone here ever have a similar problem?
Or used another map...
Would really save my life!
This library uses native (Android & iOS) SDKs and provides a React Native API on top of them. Expo does not yet support custom native modules, which means you'll have to eject from it to use this package (or any other that uses BaiduMap or other native code).
I'm guessing they probably have a web based JS SDK instead which you could try to integrate into your app via a <WebView /> instead?
react-native-external-display library not supporting in expo app. facing error null is not an object (evaluating 'RNExternalDisplayEvent.SCREEN_INFO'). I would like to use a expo in the device which has two display screens so I need to display my code based on display screen.
. Please support me with your suggestions If any other library which will support my requirement. Thanks in advance.
I have not found any other library that supports an external display for React Native. Therefore using Expo may not be the best choice.
You could eject expo and then add the react-native-external-display library, which may require you to fix some errors. Alternatively you could start a new project without expo and add the library.
I am trying to implement Auth0 on my react native app and right off the bat you need to identify your PRODUCT_BUNDLE_IDENTIFIER for the callback the server uses through this template URL.
{PRODUCT_BUNDLE_IDENTIFIER}://{app_name}/ios/{PRODUCT_BUNDLE_IDENTIFIER}/callback
But since I'm using an Expo project I don't have the ios or android project folders. Am I missing something here or is it just impossible to configure an Auth0 with Expo created project?
The Auth0 React Native package uses native code; therefore, it's not compatible with Expo.
It looks like you may be able to work around this by using the web version instead, though. Expo has a repo (possibly out of date) which demonstrates this.
I am making a Mobile app in React Native with Expo.
Now I am thinking that I will use Realm to manage state in my project.
However, I am not sure that I can use Realm on Expo or not.
Expo is quite useful to create React Native Mobile Apps easily and quickly, but sometimes there are some conflict with some modules and libraries.
So, could you teach me that Realm can work on Expo or not?
Thank you,
Update 24 Jan 2022
The feature request was marked as Complete today.
I can confirm that Realm works with custom dev clients.
Here is an expo/example you can use to get started today --courtesy of the Realm team.
We won't be adding Realm to the Expo Go app (that you download from the App Store or Google Play Store) since we are limiting the amount of native third-party services that we include by default.
Update 2 July 2021
The feature request has been marked it as In Progress by the Expo team.
https://expo.canny.io/feature-requests/p/realm
It should be included as part of a custom development client, you can read more about custom development clients here https://blog.expo.dev/introducing-custom-development-clients-5a2c79a9ddf8

From the realm docs
Expo does not support Realm
Unfortunately, Expo does not support Realm. If you use the Expo CLI or create-react-native-app to create your React Native project, you will need to "eject" your Expo project to use Realm. The installation steps on this page do not use the Expo CLI.
https://docs.mongodb.com/realm/sdk/react-native/install/
It has been a feature request for expo since 2017 https://expo.canny.io/feature-requests/p/support-for-realm
Finally, Expo now works with realm.

you can check for support state from here:
https://expo.canny.io/feature-requests/p/support-for-realm
Yes, Expo now has a way of doing this using Custom Dev clients. Here is an example app from the Realm team.

You can also see this request is marked as complete on the Expo feature request site.

I just started using React Native a few days ago and want to build my next iOS/Android app with it. However, I had a question (and I apologize in advance if this question is very basic).
If I am integrating my iOS and Android apps built with React Native, with an external service (like Salesforce for example), how do I go about using the native mobile SDKs they provide for iOS and Android? As in, what do I do to integrate those SDKs into my React Native app? Those SDKs are using native Objective-C and Java code, so how would I be able to use the JS code for React Native? I believe my understanding about this is skewed.
I looked at this link which goes into it, but it seemed very confusing and I had a bit of a hard time grasping the concept (again, I am very new to this - I've done a lot of web development, hence turning my attention to React Native, but I've done no mobile development whatsoever).
If someone could please explain how that works, and point me in the right direction where I can read and learn more, I would sincerely appreciate that!
Thank you!

Update:
There are react native packages build by open react native community if you couldn't find anything to access native iOS or android functionality you will have to write react native wrapper yourself using react native "Native Modules"
