Why Choose React Native for Your Mobile App Like Bloomberg or AirBnB

 / May 05, 2021

When you want to start making a new mobile app, you have two choices: native and cross-platform. Native apps are built specifically for one operating system, like iOS (using Objective-C or Swift) or Android, so they often run faster and have more features (using Kotlin or Java). But to make them work on different devices, you have to double the code base. This takes about 1.5 times as long and costs about 1.5 times as much. On the other hand, cross-platform apps are still universal, but they cost less to make. And React Native is likely the most popular cross-platform framework right now. It gives your app almost the same quality as native apps.

This is also the technology Designveloper use to develop several products including LuminPDF, Walrus Education, Joyn’it, or Bonux. By 2021, React Native earned more than 94,000 stars on Github, with more than 2,200 contributors updating it constantly.

What Is React Native?

The name “React Native” comes from the words “ReactJS” and “Native.” ReactJS is a free JavaScript library that is used to build user interfaces (UI). Simply put, a library is a group of lines of code that were written by someone else and do the same thing. Jordan Walke made the ReactJS library in 2011, and Facebook used it for the first time a year later. It became popular quickly because of how well it could be changed and how easy it was to use.

React Native is a JavaScript framework that is used to make mobile apps that work on both iOS and Android as well as native apps. Technically, both libraries and frameworks are reusable code. However, when you use a library, you decide when and where to call the library, while when you use a framework, the framework decides when and where to call the library. Two years after the official release of ReactJS, Facebook made React Native. React Native builds apps with many of the most popular parts of ReactJS, like components. It also uses the same design principles, which lets you make rich mobile UIs.

Is React Native Easy to Learn for a Beginner?

As mentioned above, React Native is a popular and influential framework that is easy to learn, especially for people who already know JavaScript and ReactJS.

Let’s look at the code below as an example. If you already know the basics of JavaScript and ReactJS, it’s easy to understand these codes.

import React, { Component } from 'react'
import { Text, View } from 'react-native'
export default class App extends Component {
  render() {
    return (
      <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
        <Text>Hello, world!</Text>
      </View>
    )
  }
}

The official documents for beginners are very easy to understand, and they also have code examples. More of it. There are a lot of tutorials on YouTube made by developers from all over the world to help beginners learn how to use it.

And in case you didn’t know, many top mobile apps are using React Native, such as Bloomberg, Facebook, Uber Eats, AirBnB, Instagram, Skype, Discord, Pinterest, Baidu, Wix, or Walmart. This has proved that React Native may be a choice worth considering for your project, too.

How React Native Helps Your Mobile App Development Project?

1. It is cost-effective

As mentioned above, the cost to develop a mobile application using React Native is much lower than native application development. The cost depends on the components that need to be developed, the number of developers, and the total hours required to develop an application. Native app development requires you to have programmers who know Kotlin/Java to develop for Android, and Swift/ObjectC for iOS. After all, because of the complexity of both iOS development and Android development, it is almost a double trouble to make your app compatible with both operating systems, and thus cost you more time and effort.

Using React Native saves you more money than native solutions.

The main advantage of React Native and similar cross-platform technologies over native apps is the total time taken to develop being reduced to less than half. Cross-platform app development requires you to find developers who are good at JavaScript, which is fairly easy. And if you already have a web app that has been built using ReactJS, the cost to convert it to a mobile app will be much lower than starting from scratch.

2. Code reusability and a great amount of 3rd party libraries

One of the best things about React Native is that you can reuse its code. A lot of useful components and hooks were also brought over from ReactJS. Plug-and-play means that developers only have to write UI code once and can then use it in many different places. Developers can also share their code online, just like they would with a third-party online library. Other people just need to install it and use it again. Nothing needs to be changed, how easy is that?

So, there are a lot of ready-to-use relevant components out there that were made and shared by a large community from all over the world. This means you don’t have to build everything from scratch.

benefits of React Native

With React Native, there are plenty of ready-made solutions and libraries supported by the community that helps facilitate development activities. There are testing libraries such as Jest, Mocha, etc. that aid in writing bug-free code.

Expo is a set of free, open-source tools that will help you track how your app is coming along and try out new features. ESLint is a great tool for this job, and it makes it easy to check your code for bugs that might be hidden. With PropType or TypeScript, it’s also now possible to check types more quickly. Redux is one of the most popular libraries for managing state in React Native.

3. Easy to debugging

One of the best things about having a single codebase for both Android and iOS is that it makes it much easier to find bugs. React Native code can be used on more than one platform, and you only need to give one update patch for both.

If you ask any developer, they’ll tell you that debugging isn’t the most fun thing to do. You have to spend hours looking at your code or sometimes the code of others to find the exact spot where a silly syntax error was made. With React Native, your team won’t have to spend hours looking at two different sets of code. One debug will work for two different operating systems at the same time. This will help you make sure that all platforms behave the same way.

And finally, with React Native’s “hot reload” feature, developers can now do things like handle errors while the app is running and see the results right away. In native development, developers have to stop the whole system, make the change, and then start it back up again. This will save developers a lot of time and stress because they won’t have to go through this circle over and over to find and fix small problems that happen often.

4. Easy to combine with Native modules

React Native also supports an easy way to create and use modules in Native code just like a simple component for Android and iOS. And if there are some functions that are running too slow, you can also put them in Native code to use the multi-threads support in Native for better performance.

5. Still, React Native and Native Code need to walk along together for some time before they can break up.

React Native is not perfect, just like nothing else is. Some features, like Bluetooth, Camera, and so on, are not yet supported by React Native’s development team. And the code for React Native still has trouble with some animations. But don’t worry, because of how easily React Native communicates with native code, there are a lot of open-source support libraries for React Native that are based on native code. Even if you don’t know how to write native code, you can still use it like a normal component in React Native—just plug and play—because they have all the features you need for your app.

Final Thoughts

So what should you know about React Native? Here are some key takeaways:

  • If you’re using Facebook or Airbnb mobile apps, you’re using React Native without even knowing it, you just feel like using the Native app.
  • React Native is easy to write, saving time for developers and reducing costs for your project maintenance because you don’t need to deal with two separate codebases for IOS and Android.
  • Since React Native is just a wrapper for Native modules, there’s nothing stopping you from adding Native code like Java or Kotlin, or Swift code where you need it.
  • With the active community, React Native is still growing fast with no signs of slowing down or stopping.

Above is just some of my knowledge about React Native that I can deliver. Hope it will help you.
