React Native Introduction and Installation

React Native is an open source project that allows developers to create high-performance native applications that support Android, and IOS. It is an open-source platform with many advantages, like  Faster Development, Enhanced Performance, Simple Upkeep, and Support from the community. Jordan Walke discovered the technique at Facebook for creating iOS UI elements from a background JavaScript thread, which served as the inspiration for the React web framework. To find ways to improve this prototype and enable the creation of native apps using this methodology, they made the choice to host a company-wide hackathon.

From a technological standpoint, I started my React Native journey at Prilient Technologies, where I got to know about it. React Native is made up of unique native components like Text, Input, Modal, and Buttons that translate into variations of native components that are particular to different platforms by sharing an integrated codebase. React Native can now support a wide variety of different platforms, namely Windows, the Web, and macOS.

Advantages of using React Native

  1. The ability to reuse Code:  The main benefit of React Native is that it eliminates the need for platform developers to write separate programs for Android and iOS. In reality, 90% or more of the code may be used multiple times on the two platforms, substantially improving both the effectiveness and the speed of development. You benefit from a quicker time-to-market and have less maintenance work as a bonus.

  2. Separate Plugins: Given how costly it may be to build a mobile app from scratch, React Native provides a variety of third-party plugin choices, including native and JavaScript-based modules. The third-party plugins boost the app's efficiency and usability by doing away with some customized web view advantages.

  3. Huge Community Support: React Native initially appeared in response to a need among the developer community. It has a community-driven technique as a side effect, and there are over 50,000 active contributors. The platform keeps being developed and updated by Facebook's creators, and having a group of such experts makes it simple to ask for expert guidance.

React Native Installation

Running one line of code in the terminal or command prompt is required to install React Native. React Native installation procedures, however, may differ depending on your project. Additionally, several dependents need to be loaded before you can start applying React Native.

  1. Install JDK 7 or a newer version.

  2. Set up a node.

  3. Get Android Studio installed.

What do React Native App Developers do?

Professionals that design software programs for several platforms, including tablets, smartphones, desktops, and other devices, are known as app developers. Designing, creating, and maintaining mobile apps to satisfy the demands and specifications of their consumer base or companies is their most important duty.

Planning and Analysis

App developers work closely with clients or other stakeholders to comprehend what they want and require. They help define the application's scope, features, and functions throughout the planning and evaluation processes.


The aesthetic aspects and layout of the program, such as screen designs, icons, buttons, and other graphic elements, are created by programmers as part of their task of designing the user interface (UI) and user experience (UX). By focusing on guaranteeing simple navigation, fluid interactions, and appealing aesthetics, they aim to deliver an excellent user experience.

Testing and Debugging

To find and address any flaws, errors, or usability challenges, developers do thorough testing. To make sure that the software operates properly and satisfies the requirements, they carry out unit testing, integration tests, and acceptability testing among users.

Programming and development

Depending on the platform they are targeting, app developers produce code in programming dialects such as Java, Swift, Kotlin, C#, or JavaScript. They design the fundamental functionality of the program, integrate APIs, and put the database management systems into place using coding kits (SDKs), frameworks, and tools.

Distribution and Deployment

After the program has been created and extensively tested, developers prepare it for distribution. They prepare the application for distribution by packaging it in the proper format, then upload it to the relevant app stores (like the Google Play Store, and Apple App Store).


After the app's original release, developers frequently offer continuous support and maintenance. To improve the application's functionality, security, and features, they respond to user comments, correct issues, and provide updates. This entails keeping an eye on the app's functionality, examining accident reports, and making the required adjustments.

The downsides and Risks

  1. Like everything else, employing React Native has its drawbacks, and how well it is a suitable fit for your team will truly depend on your particular circumstances.

  2. Given that React Native is still a relatively young project, its maturity represents the highest risk. Support for iOS was made available in March 2015, while availability for Android was made available in September 2015. 

  3. There is undoubtedly space for improvement in the documentation, which is always changing. The community is currently learning best practices, and several functionalities on both IOS are still deprecated. 

  4. React Native adds a layer to your code, which can complicate debugging, especially as React and the host platform converge. Due to React Native's youth, the customary limitations apply.

  5. React Native abstracts away some platform-specific aspects to allow for code sharing, but this may limit your ability to modify improvements to performance or low-level device capabilities.

  6. Like any software framework, React Native changes over time, and fresh updates are frequently issued. Updates might contain breaking changes or compatibility problems with current code and third-party libraries, in addition to modifications and bug fixes. 

  7. Process of learning and developer availability: React Native has its own set of development patterns and requirements in addition to demanding proficiency in JavaScript and React.


With the help of the innovative React Native framework, app developers can build solid applications for smartphones using their previous JavaScript skills. Without compromising the end user's experience or the caliber of the program, it allows quicker mobile development and more effective code exchange between smartphones with iOS, Android, and the Web. The disadvantage is that it is brand-new and still under development. You should choose React Native if the staff is capable of handling the erratic nature that comes with working with the latest innovations plus wants to create mobile programs for several platforms.
