React Native is the native version of the widely used web library React. The main objective is to enhance the power of React and shift to native development. React Native components are functions in their pure form without any side-effects that return what the views look like at any point in time. Hence it is easier to write state-dependent views, for updating the view when the state changes are done by the framework. The final user experience is better than the other solutions that simply render a web component inside a Web View as the UI is rendered using actual native views.
Why use React Native?
Don’t waste time recompiling
React Native provides faster development of an application. The app can be reloaded each time instead of recompiling again and again. Hot reloading provides a compilation of a new code while retaining the application state. React Native is viewed as a write-once-deploy-anywhere solution by people. It has the potential of speeding up development for applications that need to be developed for both iOS and Android and makes the development process easier for coders.
Use native code when required
React Native combines with code snippets written in Objective-C, Java, or Swift for more efficient development of applications. Optimization is easier as migration to the native code is possible. It is possible to build a part of an application on React Native and the other part using native code. Facebook is one such example.
Who’s using React Native?
Thousands of apps use React Native, from established Fortune 500 companies to the new upcoming startups. Some of them are:
• SoundCloud Pulse
Ease Of Learning
The main advantage of React is its readability, even to those unfamiliar with it. Many frameworks require one to learn a number of pre-requisites usable only within the framework and neglecting the language while React does its absolute best to do the opposite.
React Native has a great development environment. It is beneficial to the developer as it provides the functionality of repeatedly waiting for the code to compile and the app to restart while making mild edits. Any changes made to a React Native codebase are made to the running app without the need to restart.
React Native can share code between Android and iOS.
Hot Reloading is similar Instant Run on Android. Every time a source file is saved, the changes were deployed immediately on the device where the app is running, thus greatly expediting the feedback loop. It is more efficient than Instant Run, but it still breaks from time to time and requires a restart process in the application.
Evaluation of React Native
The best way to evaluate a new technology is to use it and testing was done based on the following plan:
• Create a Twitter Client, running on both iOS & Android
• Measure code re-use
• Evaluate the look and feel of the final app
• Investigate 3rd party library maturity
• Interview current react native developers
• Read official docs
• Review source code of core features
