React Native Adoption: The Journey from Beginners to Becoming Expert React Native Developers.

React Native Adoption at Bacancy Technology: The Journey from Beginners to Becoming Expert React Native Developers! www.bacancytechnology.com

Back in 2016, React Native was on the rise as a most-promising crossplatform mobile app development framework. React Native was introduced as a great time saver and a future of mobile application development. Everyone was excited to give it a try, but no one really knew whether it would last, or it will be forgotten. Today, back in 2020, we know the rising popularity of React Native won’t let it go from here. I am writing this blogpost, as in the last half of a decade, we have successfully delivered 35+ React Native projects with a team of 20 React Native developers on board. It was a great learning experience; let’s have a look at how it gets started, internal insights, lessons learned, and mistakes improved.

First Introduction: React Native It all started when the three developers expressed their interest in trying hands at the newly introduced front-end technology. React Native was just introduced, and fortunately, all the significant features of React Native were experimental. On the forum, people had various opinions like why React Native as native developers, and its versions are more performant?

Other developers were identifying as a substitute for PWA – Progressive Web Apps. So, our 3 developers decided to try their hands at React Native application.

Making Star Teams Out of Star Players In the early stage, we identified that React Native belongs to the front-end family and now an undisputed king of cross-platform development. When we finally identified that it’s mobile technology, so from various technologies, developers have shown a keen interest. From mobile to backend developers. The reason I am explaining in-detail is that specialists from different technologies and perspectives helped our clients to create unique solutions, and as a result, we got the opportunity to develop the best React Native applications so far.

Today we are a team of 20+ React Native experts.

Early Stage of React Native Development The initial days of React Native development at Bacancy Technology was a great experience. The Team faced lots of difficulties because, without the mobile experience, it was a real challenge to deploy the application. We were struggling to identify whether the issue is because of the modification in code or alteration in the library.

The Team invested countless hours in the fruitful discussion and knowledge-sharing processes.

Individual team members started creating React Native database of severe cases as well as processes that are so much helpful even today to deal with bugs and setting up new applications for a newbie.

At that time, the significant help and boost we got were from Airbnb’s React Native project.

React Native Team was dealing with a variety of techniques as well as organizations issues to put efforts into making native surprising altogether. Then Facebook and the growing community of decided to make React native applications for hybrid apps at scale.

Other Side of the Coin Over this time period, we have developed and deployed numbers of React Native applications, it was a roller coaster ride, as not everything was easy and straightforward.

Today React Native developers at Bacancy Technology is on the verge of becoming pioneers in the React Native application domain. Numbers of libraries have launched, and so many libraries have to React Native bridges, but the great thing is React Native, and our Team has become better and matures together. At Present, React Native repositories has over 17K commits and 66K stars. Hundreds of React Native libraries are there. Most popular and top React Native component libraries can be found here.

Yes, Airbnb has stopped using React Native.

Still, being a $38 Billion worth organization, they can afford to hire enough developers to work on individual platforms to make Airbnb app an uninterrupted experience for their end-users.

The React Native is growing and so is our Team Now our React Native consists of 20+ experts and is still growing so fast. Now there are numbers of libraries available, tracking error is much easier, and from startups to SMEs, we are using React Native for all the shapes and sizes of our clients as we firmly believe that React Native is the future of mobile applications. After investing thousands of hours, from a newbie to now React Native expert and learning from our own mistakes, I thought that I should write down the most common mistakes to avoid while developing React Native application.

Top 7 Common Mistakes to avoid while developing React Native application

01. Inappropriate Planning of Redux Store Whenever a project is assigned to the developer, the most common mistake that I have identified is developer invest more of the quality time in focusing the app layout, instead of giving enough importance to the data handling part.

This is where leveraging React-Redux seems like a smart choice, as it helps with managing and storing the data correctly, as well as it also debugs the app states. If it is utilized efficiently, then Redux is an open-source JavaScript library and a powerful tool to manage the application data. I would personally like to suggest you not to make use of Redux when you are building an app for a startup because sometimes small changes will require you to write long lines of codes.

02. Make sure to Mention Unique key into Flat List item Remember to specify a unique key into your FlatList item; if you do not specify it, then it will re-render every single time into the modified list. You will end up having a poor performance of your application, and it will result in bad user experience. So, make sure to provide a unique key to enable a stable identity. < FlatList data={ [11,12,13,14] } keyExtractor={(abcd, index) => item.key} renderItem={({abcd}) => < Text >{abcd}< /Text > } /> To help your application from the performance issues due to re-rendering, make sure not to avoid it.

03. Mistakenly Leaving console.log() statements in the production app When it comes to debugging the app, Console.log() statements are a blessing. As it especially helps you identify, specifically, which line of your code is not working as anticipated. Leaving But, leaving console.log() statements in the production code may have an adverse effect on the performance of your application.

04. Not Reading external modulesâ&#x20AC;&#x2122; codes External modules always make things easier as well as faster as they come with documentation, and it has never been uncommon for developers to save time through external modules. However, it wonâ&#x20AC;&#x2122;t be proven useful or as anticipated because modules break, and this is the reason why developers should read the code because doing so helps to identify whatâ&#x20AC;&#x2122;s wrong with the module and also helps to address the issues.

05. Binding functions inside the render method

render(){ return( < TouchableHighlight onPress= {this.callme.bind(this)}> Press Me < /TouchableHighlight > ) }Here I am iterating the TouchableHighlight inside the map function. It simply breaks the performance optimization because it creates different callbacks while rendering. However, this issue can be resolved by binding callme() method or using property initializer syntax.

callme = () => { console.log("Pressed"); } render(){ return( < TouchableOpacity onPress={this.callme}> < Text >Press Me< /Text > < /TouchableHighlight > ) }

06. Not Conducting Unit Testing Not to write a testing unit is the most common mistake so far, because the app still works regardless of whether you write unit testing or not. However, doing so, you are leaving the appâ&#x20AC;&#x2122;s fate at the mercy of users, because you will only have a result once your users download it and use it.

Unit testing lets you assess the various features as well as parts of your application independently. It ensures that each function of your application is performing as expected. If you will write the unit test during the development stage of your application, then itâ&#x20AC;&#x2122;s easy to identify the bugs and track the source of glitch later on.

07. Not optimizing images Optimizing the images while building the React Native app should be a high priority task because it helps to seize the images locally and upload them to the cloud storage to improve your appâ&#x20AC;&#x2122;s performance and make your app lightweight to some extent. So next time, while building the React native app, make sure not to forget to optimize the images.

Wrapping Up So here I have listed seven common mistakes that you should avoid while building React Native application because your aim should be making fewer mistakes and gaining traction to build top-notch mobile apps using React Native.

However, there are a series of other things that you should take into consideration while building React Native application. If you are interested in building a React Native application with the highest performance, then hire React Native developers from us to build intuitive, visually stunning, robust, scalable, engaging, and user-friendly cross-platform mobile applications.
