When a framework is believed to be beneficial for mobile app developers, its myriad benefits also automatically appeal to entrepreneurs with its ability to reduce cost and time.

However, to understand that the limelight React Native is getting is not too exaggerated and it is comparatively better than native app development, we are going to go through a tutorial of this framework in the following discussion.

This tutorial will help beginners in the space of React Native development broaden their perspective about the technology and know what all factors they should consider when opting for React Native for mobile app development through this tutorial.

Who Invented React Native?

This open-source mobile application framework was created by Jordan Walke, a software engineer at Facebook.   He released an early prototype of React called “FaxJS”.

React was first deployed on Facebook’s News Feed in 2011 and later on Instagram in 2012.  In May 2013, React was open-sourced at JSConf US.

In this tutorial, we shall have a broad view about react native and also have some topics  should go through before starting learning.

What is difference between React JS and react native?

react native tutorial

Due to obvious presence of React in React Native framework, entrepreneurs and beginners often get confused about their exact use and applications in the world of development.

It is therefore important to imbibe the fundamental difference between React and React Native technologies. React uses React DOM for rendering web development solutions while React Native stands as a custom solution for rendering React files for mobile equivalent.

React Native uses native components as building blocks for developing mobile apps unlike React that uses web components. As a first-time learner of React Native, it is inevitable that you must gather enough basic overview of the React concepts such as its class, components, JSX, state and more.

Even if you have know how about React, you will have to explore the Native components of React Native that makes React code work for Android and iOS.

Cultivating basic insight into all the benefits and limitations will help fuel the development process and make developers more proactive, vigilant and confident in their space.


Slim Coding: Write once run everywhere

The most exhilarating part about working with React Native app development is that it allows you to adopt single code base for all platforms (Android, iOS, Windows).

This goes to imply that the team of Native developers would not have to write separate codes for different target platforms. They can follow write-once-run-everywhere approach, having to code the app just once and make it live across available platforms.

Rapid App Development

Another pro that is most likely to be the comforting answer to React Native conundrum is that the framework facilitates rapid app development, minimizing both the team size as well as time required to finish the project.

The mobile app development company does not need to involve too many developers especially to individually work for all platforms. As single team is enough to look after all the requirements efficiently and project doesn’t demand extensive timeline, the overall efforts for design, development and testing are too massive.

Lean Learning Curve for Web Developers

React Native is based on JavaScript and existing web developers who possess good familiarity with this JS can easily get their hands on React Native app development.

Hence, it is not a massive struggle if you want to learn and eventually switch to mobile app development using React Native as a core technology in this tutorial.

Open Source

react native tutorial

At the start of any mobile app development project, developers emphatically seek open source nature of the technologies being used. React Native, being the open source, thus pleases developers by allowing them to freely inspect code.

Not only that, due to being open source, its library is generous and updated with components that even work for rare platforms like tvOS.

Comfortable team composition

The nature of React native development is such that it also comforts entrepreneurs who often brood over assembling great number of developers to create a huge team.

The framework allows you to dispense with a small size of development team which is composed with merely:

  • Tech consultant
  • Project Manager
  • React Native Developer
  • UI/UX Designers
  • Business Analyst
  • QA Specialist

In case of pure native app development, you may end up choosing almost double the number or more is depending on the project size.

How much does react native cost?

Scalability for future

Even after hearing about its several incredible benefits, what developers and app entrepreneurs worry about is whether or not React Native is flexible and versatile enough to fulfill unpredictable scope of app scalability in future.

As business grows and marketplace evolves, the need to meet the loads of requirements of increased real-time users becomes inevitable. To their relief, this overwhelming expectation is fulfilled efficiently by the flexible capability of React Native cross-platform framework.

If developers are experienced and aware of how they can tune React Native structure to handle increased volume of customer activities, your app can be as successful as one of those big brands like Facebook, Instagram, Airbnb or Walmart. They are all powered by versatile React Native.

Hot Reload Option

Another technical aspect that developers ponder over while figuring out technologies is the amount of time consumed when actually writing and running application code. Thankfully enough, React Native affords hot reload solution which is a brilliant time-saving functionality.

With this capability in place, developers find it easy to view in real time how any change in code appears in target device. The action of checking the effect does not demand burdensome efforts, which lucidly proves that React Native has developer-friendly environment.


Poor connection with device’s Native environment

react native tutorial

A little unpleasant blow for React Native developers is that it does not directly interact with device’s native elements such as Camera, Voice recorder, etc. this is the kind of challenge that even its closest alternatives like Xamarin and Flutter don’t seem to solve completely.

Hence, in certain technical dilemma, native app development outweighs the cross-platform capability of React Native to an extent.

Limited Native APIs

In React Native, developers are restricted from using certain Native APIs as there isn’t much support for all Native APIs. However, the technology is working on providing support for those Native APIs. For now, this is one of the plights where Native app development seems to overshadow React Native power.

Insufficient Third-Party Libraries

third party

Another down point in React Native development is that it lacks third-party libraries. Developers have to depend on native modules to leverage libraries – which somewhat adds to development efforts in the long run.

Adoption rate of React Native

By mentioning all the pros and limitations associated with using React Native for cross-platform development, we could clearly see how React Native, when compared with other tools or app development methods, emerges stronger and more reliable.

The reason why React Native still holds its significance and is widely adopted is that it has all the functionalities developers need for cross-platform development process.

Pros the framework offers are too great to be overwhelmed by its limitations, or by native app development approach. This is why there is a steep rise and interest in adopting React Native for creating sophisticated, business-class mobile apps.

To understand the size of React Native’s adoption by global businesses, we must be driven to take a good look at those eminent big brand names that turned to RN to build the backbone of their applications.

Who are using react native?

Apart from the companies that are now starting to feel positive about React Native for mobile app development, here is the glance at globally recognized applications:

Why we use React Native?

The reasons to use React Native are that it is a popular framework that is used to build web applications. React popularized the use of a virtual DOM, this in turn greatly increased render performance for web apps.

This open-source mobile application framework maintains a virtual representation of the view hierarchy.  So, when changes are made, you no longer have to do expensive operations on the view hierarchy.

React uses an efficient diffing algorithm to compare the virtual hierarchy and then necessary changes are made to the actual view hierarchy.

Encapsulation of components is another fascinating principle of React. React encapsulates each single component into a single file.  With React Native, you can save a lot of compile time.

React Native helps build app that can work across multiple types of platforms including iOS and Android.   This cross-platform feature helps large or small company to save their time and money.

React Native has Rich Text Editor which helps increase the overall productivity.  The key benefits of Rich Text Editor are that it will not crash, hang and lose syntax highlighting.

React Native: Possibilities and Potential
