With the upheaval, or say, the breakthrough from the past, has created a pressing need for a shift from business models with real-life approaches to digital platforms with a technological approach to solving human problems and their growing needs. Developers these days have come up with excellent ideas to build a mobile app using React Native that runs on both iOS and Android.
With the view of digital platforms revolving as the central focus for our everyday practices ranging from shopping to communication, from global awareness to entertainment, from gaming to healthcare; hence with these, the years-old businesses to new start-ups all have realized that it is indispensable to keep up with digital platforms to survive in the market in this century.
React Native has been a sky-scraping tool for the app-development industry. And also, it’s been most suitable for companies to do the same.
What is React Native?
React-native came into the limelight for the first time in 2015 with the launch of the massive success of Facebook. Its popularity and usage gradually increased, and now it is the first choice of every developer. Most apps, from social media apps like Instagram and Facebook to human help apps like uber eats, are built with React-native.
Why React Native?
Well, anyone reading this article might undoubtedly be questioning the same. So, here’s the answer that would probably change your doubtful sight to a convinced view for the use of react-native.
There are plenty of reasons for REACT-NATIVE to win developers’ hearts globally.
Most companies prefer the development of an app using React Native because they do not need to hire two teams of developers maintaining 2 code bases, one for iOS written in swift or objective C and another for Android written in java or Cartland. Instead, by react native with a single codebase that can run in both iOS and Android, the company saves the funds and the efforts of hiring multiple teams.
It saves time after creating two native apps that could probably facilitate iOS and Android separately to a single codebase that could cross-platform and run in both. This is possible only with the use of React-native.
React-native has a fantastic feature wherein “Out-The-Air” updates can be made on the backend side even when the user is actively using the app and is reflected immediately at the user interface. It is also made accessible instantly. And insightfully or more specifically, the user does not have to go to the play store or an app store to make the required update since it gets updated automatically. This feature is also called “Fast Refresh.”
Apart from all these benefits mentioned above of react native, the most fantastic feature of it is it allows easy migration of UI tools and many other tools to personalize the application to its best.
So, these magnetic properties and enduring react-native features would have caught all your attention.

How to Build a Mobile App using React Native?
There are two ways to get the best output or to get the finest application done; one is by hiring a MERN stack developer and another by developing the same by using react-native and having basic knowledge of JS hand in hand.
So, let’s straight look into both the approaches in-depth:
Hire a MERN Developer
Here MERN stands for MongoDB, Express.js, ReactJS, and Node.js. Fundamentally, MERN is an assemblage of technologies that helps in the development of an app and makes the process faster and easier.
Hiring a remote MERN developer is advisable since it facilitates speedy delivery of a practical solution. Also, remote hiring enhances the project’s scalability and magnificent flexibility. Before hiring remote developers, you will need to change your management style and workflows, including plans, functions, etc., to accommodate or successfully incorporate the remote workers.
Another great or greatest of all advantages is its cost-effective technique since it eliminates the overhead costs of developers for the company.
So, building a mobile app using React Native by a developer is quite advantageous.

Factors to Keep in Mind While Hiring:
- The motive of the project
- App Type (small, basic app, large sized, complex app, etc.)
- Funds availability
- Designing qualifications
- Programming skills required
- Soft skill assessments
If one hires a MERN developer who could use native JS and easily accommodate with react native, that will increase developmental capability and productivity and help market expansion. Since there are no fund expeditions over different teams hiring for iOS and Android, the same can help in spending funds over app engagement.
Also, hiring remote MERN developers is tremendously advantageous since they enhance the company’s productivity, increase efficiency, and also saves assets of office space costs and accommodation costs.
Develop the same by using react-native and having basic knowledge of JS hand in hand.
Since we are starting to build a mobile app using React Native straight from scratch, there are some extra steps you need to follow.
Download NPM and node.js in your system.
Note: if you already have it done prior, jump straight to step 2.
Install Expo CLI
Well, there are two ways to build react native apps:
- Plain react native, i.e., react native CLI or say react-native command line interface (It is the priority of people who have basic knowledge of Android and iOS programming)
- Expo CLI (set of tools and framework that sits on top of react native and hides a lot of complexity from us it makes; it is incredibly fast and easy to build react native apps.
Note: If you have never done any mobile development before expo is the way to go, you can build and run your first app within a few minutes.
So, since we are discussing things from an elementary and primitive level, we will go ahead with expo CLI.
To do so, go to a new terminal on the system, and type the command as $ npm install -g expo-cli
Start to React Native Project.
- Once you have installed the expo client, you will be asked to choose the template and the workflow. So, choose managed workflows over bare workflows because bare workflow again requires building an iOS and an android file which the managed workflow doesn’t need) and opt for a blank template. Once it is done, type the name of the project and then wait for the CLI to generate files and extract packages from NPM.
- To test your application, you have multiple choices like an iOS simulator, website, android stimulator, or mobile device, depending on your working environment. You can hire one from a mobile app development company if you don’t have one. Once done, you can easily install the expo app.
- Now open the app.js file, a primary react native component. Here we import react-native parts, stylesheet, text, and view from reacting Native. Also, note here that we don’t have HTML attributes like an anchor, div, etc. instead, we have function and class components. Still, it’s always better to use function components because they are more straightforward and more lightweight hence, function.app ().
- Introduce style object in return command under function.app
- Now with style as object and stylesheet. Create and add all style commands required (create contains a property called container that includes all the styles).
To add multiple screens to react native apps.
Use conditional rendering to add multiple screens to your react native app.
Fetch data in React-native.
- For loading, we use the effect hook to perform the slide function. We will be fetching the data from the rest API server. To do so, go to app.js and add API_KEY and apiurl under the function app () object.
- By use of react.setstate() add item and store information.
- Call the fetch method in the estate hook to fetch the data.
- Add fetched articles under the <home> component using data properties.
- Now the data has been fetched, and it is also passed to the home component. So now you can hire a front-end developer to make the required modifications. (in terms of designing and other styling components)
- Now call JS map (), which translates these properties and the components we use to their native widgets and displays the data on the screen.
- Finally, our app screen will show the data stored in the backend.
- Now, whatever appears on your screen post the previous step seems like a random collection of words. So, it needs proper style, size, and font; now, it is a complete game of UI designing.
- You can make it more engaging and attractive by adding images, statistics, URLs, etc. You can add any design element that you wish under the stylesheet. Create a hook.
- Once all designing work is done, the app is ready to be used.
To Sum Up
React Native has the developers’ whole hearts and hopefully yours by now. Hiring a remote React Native developer is equally advantageous in the final output that is more design-versed, eye-enticing, and more productive. From planning to designing, the React Native developer knows it all to their best, so to make an app more scalable with less time-consuming and cost-effectiveness, the React Native developer should be your only choice.
