What Does a React Native Developer Do?

React native, an open-source mobile application framework, was released by Facebook in 2015. It is the most used Mobile framework to build native applications.

Today we will talk about the mobile version of the most used JavaScript library, React Native.

React native allows the developer to target iOS and Android applications simultaneously. The apps built are native and use web technologies. They usually focus on the front end of the product.

React native developers are front-end developers, and have to also know how API services work, as many times they need a third-party service or to share data from the native application to external sources.

What does a React Native Developer know?

A React Native engineer knows both, JavaScript and how to manage the native platform. They know when to maximize code reusability. Developers must know functional and object-oriented programming.

A React Native job opportunity is usually looking for a developer that can build performant mobile apps on both the iOS and Android platforms. React Native developers will need to develop applications, work with the team, and participate in other parts of the infrastructure.

React native aims for pixel-perfect and smooth user interfaces. By pixel-perfect, It is meant that the resolution and design of the application are very appealing. Developers diagnose platform issues and fix bugs for better performance.  

Turning web applications into mobile applications 

One great feature that is offered by React, is the ability to migrate React web applications to React Native. If you currently have a React web application, you can turn it into a native mobile application. This is efficient and time-saving, as you don't have to build the mobile version from scratch.

Reach out to the open-source community to encourage and help implement mission-critical software fixes—React Native moves fast and often breaks things.
The skillset within the stack of the developer for this case is based on JavaScript. The developer works with native building tools like Xcode for IOS And Android Studio for Android. Besides JavaScript, many developers choose to use TypeScript and ClojureScript.

You can choose how much to use React. There is a grade of usability, you can use it as much as you need. A whole app from scratch can be built, or you can use it for your existing mobile projects. A single codebase can be shared across many platforms. With React Native, you can maintain the code in two platforms and still use a single technology. 

Native apps without compromising the user experience. Many components such as View, Text, and Image are mapped directly in the building blocks of the user interface.

React has one of the fastest iterations. You see your changes as soon as you save. There is no need to wait for the build to be done to see the progress. You save, then you see the changes, and you repeat the process. This allows developers to see the version while developing it.

The hybrid framework has been created and developed by Facebook. The first release was in 2015 and it has been maintained since then. From 2018, React Native has the second number of contributors in a single repository in the entire GitHub community. Since the contribution of Facebook, many other companies such as Callstack, Expo, Infinite Red, Microsoft, and Software Mansion have supported the platform.

Facebook is behind both technologies, React.js and React Native. The web version was built so that they could build the social platform. Later on, React.js was released as open-source. In the beginning, they had trouble with their mobile version. As they had to maintain two separate codebases. One of IOS, and the other for Android. Fortunately for the company and every developer, React Native solves the problem perfectly.

To give you an impression of how much React Native is currently being used, out of the top 500 apps in the US market, 15% are built on React Native. Among them, Facebook, Instagram, Skype, Tesla, Walmart, Discord, and Bloomberg.

In conclusion, React Native, the most used JavaScript framework, has two versions. The web version called React, and Native, the mobile version. It was developed by Facebook to help them develop their platform and later on, they decided to make it open source. There are no limitations in the gradience of use at the time of using react. You can choose to build a whole application from scratch or build something based on your existing project. React Native developers are front-end developers and they work closely with designers and Back-end developers too. Their JavaScript Knowledge is necessary and their ability to use API´s too.  It is the most used platform to build native apps, as it allows us to build an application for both operating systems at the same time.
