I was looking into comparison between Cordova based hybrid apps vs React Native and was confused how are React Native modules different from Cordova plugins?
(in case both are same, then why is FB reinventing the wheel)
Does React Native modules support all devices feature like Cordova does?
Thanks,
Rohit
How are React Native modules different from Cordova plugins?
React Native Modules and Cordova Plugins both perform the same task: they allow the calling framework (React Native or Cordova) to invoke specific native functionality which is not available by default in the framework.
As such, the native functionality provided by a React Native module may be the same as provided by a Cordova plugin, but they will have a different interface to the framework which sits above.
Therefore, it's possible to factorise out the common native code and have a native component which is made available as both a React Native module and a Cordova plugin.
For example react-native-background-geolocation vs cordova-background-geolocation.
Since only the interface to the native functionality differs, there have been some attempts to write a bridge to allow Cordova plugins to be used as modules in React Native, for example react-native-cordova.
The main difference is that Cordova uses HTML5 + CSS + JS for building hybrid apps. Your app will still run inside of webview. Although I've never worked with it, I can comment something
What does it mean?
I'm not sure about support of important features, like bluetooth, graphics, images (Core Graphics, Core Image), other core features
Performance also won't be the same as native app
React Native is different here, because all it does - translates your JS code into native code for platforms. The performance still can't be the same, but it's comparatively high.
Also, you can use native modules for your application in case you can't find one already created by others, so every feature accessible under platforms still be reached from React Native

I worked on a React Native library and we build some native functionality like implementing BLE. So we did that in Android and iOS folders under React Native. Now we want to use the same functionality in Native project iOS and Android (Native). Reason we built in React Native is coz we have a different project thats in React Native. But now we are trying to use this library in native projects. We are not sure how we can achieve that.
We don't have anything built in this Library other than in Android and iOS folders under RN project.
Attaching image of how we build or functionality in React Native but under Android and iOS folders. (We can just copy pate and create a native library but trying to avoid that).
I don't think so. you probably have to separate them to 2 different libraries and publish them independently
Since I did not get any answers from the previous post, I am posting again.
I have many experiences in Android native development but am a beginner in React Native. Wish to build a React Native app but need to find out these answers before I can start making architecture:
Is it possible to import a native Android module/ SDK (which is programmed in Java/ Kotlin) into React Native app? (I believe it is yes as I saw many good articles on the internet)
If I import the native Android module/ SDK to React Native app, does the app runs on iOS devices as well? Able to use APIs which native Android module/ SDK supports? (Or do I need a native iOS module/ SDK for iOS itself?)
I think this is similar to question #2. After importing the native Android module, does it also run on the web without a problem?
Looking forward to getting answers.
Many thanks,
Yes it is possible to integrate Android Native Modules.
No app doesn't run on iOS device if you have only Android SDK, You need to have a native iOS module to integrate iOS Native Modules.
For Web, I don't think so since both are native modules.

I am completely new to React Native and I would like to develop my first RN app. I have experience with React and building iOS apps with Swift, but I have never tried React Native.
I see that there are two main ways of creating a new app, either with react-native init or through Expo. Which is the preferred toolchain for someone of my experience? Can somebody explain the tradeoffs between the two?
If you are just trying to learn, I would suggest you to use the cli.
The main difference between react-native init and expo is that you cant add native modules and can't use packages with native language that require linking. Overall if you are creating a small project that doesn't require functionalities that the cli, go for expo. But if you are builidng a decently large project or if you are just trying to learn your ways around react native, I would chose the cli. IMHO
I am new to React Native and first of all it is the best framework for building cross platform applications using the JSX.
Few questions that are stinging me to know that:
When we run the app created with react native, does it convert the
Javascript code into native Java or Objective-C and then this native
code is executed in the phone to run the app and get the output?
When we pack the application created with the React Native, does we get the pure compiled native code in this file i-e .apk or ipa(same as created with pure Java or Objective-C)?
I am using the React Native application development method Native Code development(Android Studio + React Native + Virtual Device - followed the documentation on the React Native site).
Question #1 is already asked on the stack overflow but i am failed to understand because i am beginner in react native.
Please can some one answer my questions in simple and easy explanation?
Again, please easy words explanation !!!
No, the React Native framework is native code, but your Javascript code is included in the build as Javascript and interpreted at runtime. This is how you're able to debug code changes without rebuilding your app, and use services like CodePush to deploy new Javascript bundles to already deployed binaries.
Yes, react native is essentially a JS library built on top of Java and Objective-C, and compiles to native code.
Is it possible to build for android with objective-c native plugin in Unity3D? It builds when i press "bıild and run" without error but can't test with emulator since i use native plugin. I don't have an android device either.
Any help would be appreciated.
You'll be able to build for Android, but you won't be able to use an iOS plugin in Android.
In my projects I have multiple plugins for various platforms. By isolating platform dependent code with #if UNITY_platform, where platform ranges from IPHONE to ANDROID, you can effectively have a single code base with multiple platform plugins, that implement functionality in that single code base, by using dependency injection.
