He also added that Facebook would soon find a better solution to deliver a superior mobile experience.

React Native is known for developing responsive, feature-rich, powerful, and business-empowering applications.

In this article, we have outlined the top advantages of React Native app development and the reasons why businesses should consider it for developing applications.Why Businesses should prefer React Native app development?Highly Cost-effective For start-ups and small and medium-sized businesses, the main concern is the budget factor.

Since React Native is a cross-platform framework, the businesses can get high-quality mobile apps developed for iOS and Android simultaneously through a single codebase.

This reduces the development cost and saves time to a great extent.Easy Learning curveFor building iOS apps, developers need to learn Swift and Java for Android apps.

This also gives a competitive edge to the app owners.Open-source Framework supported by FacebookReact Native is an open-source framework supported by Facebook which uses native UI controls and gives full access to the native platform.

Debugging involves thorough checking of the code and helps in the early detection of error conditions.

Fixing these errors or bugs during the development process, instead of fixing them in the production stages can be highly economical for every React Native development company.

The React Native framework supports this tool through its remote debugging abilities by default.So how does this tool work?When your React Native app is running on Android Emulator and you have to access the in-app developer menu, press ‘Cmd+M’ on Mac or ‘Ctrl+M’ on Windows.

Now, a menu will appear and you need to click on “Debug JS Remotely” to open the Google Chrome debugger.

From here, you can add breakpoints and easily debug the app using the ‘Chrome DevTools’.The Developer MenuThe developer menu comes with a plethora of options for the developers to do various things, as given below:Reloading option for reloading the appEnabling Hot Reloading for watching the changes accumulated in a changed fileDebugging js remotely for opening a channel to a JS DebuggerEnabling Live Reloading for allowing the app to automatically reload when the save button is clickedToggle Inspector for toggling an inspector interface.

This interface has some other tabs too, which include a tab for performance and for networking that show us the HTTP callsReact Native DebuggerThis is a stand-alone desktop application that works on Linux, Mac, and Windows and one of the most recommended debugging tools.

This knowledge will help to deal with the unthought issues and in the long run, it will ensure an enriching experience for the users.So, in this article, we have outlined some of the most common issues and errors that the developers could encounter with the ways to deal with them.

We have also mentioned a few limitations of this framework.Common Errors Encountered during React Native DevelopmentError in Development Server:At times, the React Native developers may face the issue in which the screen shows the message- “could not connect to the development server.” This error occurs when there is an issue with the metro bundler.

So, the developers should turn off the previous metro bundler, then navigate to “Your Project Directory” and hit the command- “npm start.” Lastly, they need to open another tab to run the command- “react-native run-android/react-native run-ios” and this issue gets resolved with ease.Error during App Registration:When an app is developed in React Native and the developers run the app, they may view the error which says- “Your App is not registered.” This error message arises due to a small mistake while creating the app- not writing the correct app name in your app.json file.

The issue can be resolved by providing the right path for files.Error in React Native Firebase library:In case the Firebase library for React Native is not linked or even installed properly, there are chances of getting an error that shows- “Firebase.h not found” or “FirebaseCore.h not found” messages.

This error can be dealt with by referring to the variable in the description of the issue.Other Challenges associated with React Native developmentPerformance Issues: Since React Native is still in its infancy, several performance issues arise.

However, the Facebook team is working on the development of a new architecture that seems quite promising and will help in solving the issues of bridge serialization and also improve the communication between the JavaScript and native elements.Debugging and compatibility issues: Developers may face several issues with debugging tools or issues like package compatibility.

Let’s run through them.The Best React Native UI Libraries to consider in 2020React Native ElementsBeing one of the most popular and easiest component libraries, ‘React Native Elements’ is known for providing a consistent look and feel to the apps.

It is coded with native JavaScript.

In this library, the amount of boilerplate code to be written is comparatively reduced, as react native elements is based more on component structure than the actual design.React Native MapviewReact Native Mapview provides map components for both iOS and Android platforms.

The zooming feature can be enabled to the specific coordinates or markers or it can be even animated.

The kit provides a wide range of component APIs like MapView, Callout, Marker, Polyline, Polygon, Overlay, Circle, etc.React Native Vector IconsThis is an extremely useful library that contains a rich set of 3,000+pre-made icons.

This library is apt for logos, buttons, etc.React ReduxRedux is a library that is standalone and can be used with any framework or UI like Ember, Vue, Angular, React, to name a few.

Also, in the year 2018, the Facebook team announced the re-architecture of this framework for addressing all the existing issues faced by engineers during React Native development.

Today, React Native has become one of the most preferred choices of developers for creating modern-day SPAs and mobile apps.React Native is still progressing and a host of React Native development companies have emerged across the globe, due to a massive demand for this framework.So what’s new in React Native in 2020?

In this article, we will have a glimpse at React Native’s enhancements in 2019, the basic React Native architecture, and its new update in 2020.Highlights of the React Native in 2019In 2019, React Native introduced several versions with some amazing modifications and tools.

Hermes enables Android apps to use lesser memory, faster launching and apps are much lighter in size.The helper was updated too after a long timeAuto-linking of the native modules, another new feature was introducedCocoaPods were merged as a section of the React Native IOS project Updates in Version 0.61 The hot-reloading and live-reloading features were replaced by the well-functional Fast Refresh feature.Another significant feature- React Native doctor was launched in this version which ensures that migrations and updates become hassle-free.Updates in Version 0.62 The team announced that Flipper, a feature that enhances the debugging of mobile apps in both- Android and iOS, will be introduced.Overview of The Old React Native ArchitectureMain objective of this framework is to help React Native developers to write JavaScript React code so that UI can be displayed correctly at the same time developer can access the native capabilities in the app.

Due to the bridge that is being used for communication, there was an inherent delay in the synchronization between the native and JS code.Highlights of Re-architectured React Native Framework in 2020To address some of the existing issues related to the bridge in React Native, Facebook has taken the important step of going for a revamp in the architecture of this framework.

It will help in better native interoperability, faster startup, elevated UX of core components, etc.Another update will focus on a new set of APIs for the initialization of React Native.
