This includes Geolocation, Camera Roll, Vibration, and others.

The second objective is also fulfilled, which is to use the REST endpoint and integrate the Apollo client into any API endpoint to query desired results in a React Native and Expo app and pass the data between two screens.That's it!
Apps are built using HTML, CSS, and JavaScript, so the way you build the UI and add functionality is pretty much the same as how you do it in the web. When it comes to code, Ionic is the easiest to learn, especially if you’re coming from a web development background. On the other hand, if you’re looking to develop simple apps with a decent amount of animations, and you expect your users to be using more recent devices, Ionic should be a great option, as your existing web development skills are directly transferable.Here is the output you are going to get after this step: By now, you should know which among the three frameworks to pick based on your project needs.The stack navigation pattern allows transitioning from one screen of the app to another while managing the navigation history. No matter how much Drifty Co. tweaks the framework, the performance penalty is just too great when you’re running the app on a web view. Even though this collection is small, the community makes up for it by bringing a lot of native modules for accessing all kinds of device hardware by means of a JavaScript API.Also, add the corresponding styles to this component:After the app has finished building and this process triggers the metro bundler, you are going to get a prompt asking for permission when the app runs for the first time.Time to start building something great!In this tutorial, let us build a simple QR code scanner app in React Native by implementing one of the functionalities this module supports, called Barcode scanning.In this tutorial, we only explored the barcode scanning capability, but the same principle applies if you have other goals in mind that also use the device’s camera.It also helps your React Native app to communicate with the native operating system using the device's hardware by implementing some helper methods.The development workflow looks pretty similar for each framework:The demonstrated example is based on Expo SDK 38.In this article, we’ve taken a quick look at what React Native, Ionic, and NativeScript have to offer. The Apollo integration is working and you can start displaying the data in the app.This means that the camera is working as expected and now you can leverage this to scan QR codes.Mobile hybrid frameworks are relevant nowadays because they allow developers to deploy mobile apps faster than their native counterparts. Now, let us go back to the app and test it out.To begin, let us generate a React Native project by using the command below from a terminal window:Out of the three, Ionic will have the worst performance while NativeScript and React Native will have a performance that’s very close to their native counterparts.You are also going to see the initial loading screen.For iOS devices, you have to install the pods as shown below:React Native comes with a small collection of hardware APIs to access native device features. I am going to use a real Android device for testing.When testing on an Android device, please make sure that the device is connected via USB, and make sure that USB debugging is enabled as well before you run the previous build command from a terminal window.The major highlight of this new release version is that routing of screens is now based on component configuration.If you’re looking to develop a game with lots of animations and moving parts, you should stay away from Ionic because its performance is not just going to cut it. If the app uses only one stack navigator, then it is conceptually similar to how a web browser handles navigation state. As for native plugins, they can be debugged using Android Studio or Xcode.Let's install all the required dependencies to integrate the Apollo client and request the REST endpoint using GraphQL queries:The difference between the three is centered on the tools used for developing and debugging apps.To follow this tutorial, please make sure you have the following installed on your local dev environment:Thanks to great community-built components like RNCamera, React Native apps continue to grow as great alternatives to native mobile apps.On visiting the details of any coin in the list, the following is going to be displayed.With the basic configuration of a stack navigator working, let us now fetch the data from a third-party API using the Apollo client in the next section.For Android users, there is no extra installation requirement at this point.And because the good people at Drifty Co. always look into improving Ionic’s performance, you’ll usually only notice the performance difference when your app needs to access native device features.That's it for the installation process for the OS platforms.
