What React Native development is

Although you may know what React Native is, it would be useful to refresh your memory about the subject. A clear vision of the work specifications of a professional you are looking for is a must. So, let’s start with a brief account of the React Native platform and its basic features. 

React Native is a JavaScript framework that allows developers to create native mobile apps using a JS codebase. It was created by Facebook and quickly became popular worldwide among developers for its cross-platform capabilities, speed, and unique features. Currently, it works with multiple platforms, including iOS and Android.  

In nature, React Native code is a combination of XML-based markup and JavaScript, or JSX. Native rendering of the applications in React Native happens through Objective C (iOS) and Java (Android) APIs. With RN cross-platform structure, developers can reuse up to 90 percent of the code. It saves their efforts and accelerates up-to-market time.

Working with React Native, an app doesn’t use web views because the framework includes native UI components. It means that the system will consume fewer resources to perform seamlessly. 

Among other prominent features that make RN stand out from other native mobile development platforms are live reload, superfast and GPU (Graphics Processing Unit) usage. 

Pros and cons of React Native framework:

Pros 

• Fast development process;
• Performant applications; 
• Stable and extremely flexible framework;
• Hot reload feature;
• Simple and handy UI;
• Large and supportive developer community.
  

Cons 

• Debugging and compatibility issues;
• Lacks custom modules.

What skills are necessary for React developer 

To choose a great RN developer, you need to know what professional skills & personal qualities he or she should represent. 

Hard skills

Starting with the practical skills a good React Native developer should have. These core skills are the decisive factor for RN developers’ choosing. Thus, the first thing to do in the interview is to find out if an applicant has the following skillset. 

Excellent knowledge of Javascript 

So as React Native is a JS framework, a candidate should have an impeccable knowledge of JavaScript itself. It is a vital point for React Native cross-platform mobile development. Javascript knowledge will help React Native developers to understand the flow of RN mobile apps, structure their logic, and add new components. 

Android and iOS apps development experience 

A great RN developer should have experience working with Android and iOS apps. A developer must be able to tell the difference between those two development types. Besides, he/she needs to know both Objective-C/Swift (iOS) and Java/Kotlin (Android) to run an application on different devices. In addition, it’s vital for a developer to know the best React Native databases and be able to integrate them with iOS/Android apps.

Knowledge of React basics

Next, make sure your potential RN developer knows JSX (JavaScript XML) and React Virtual DOM concepts. Additionally, a decent candidate should know the component lifecycle (mounting, unmounting, updating, error handling). 

Work-related tools

The experienced React Native developer will most likely know some extra tech or software tools to streamline the workflow. For instance, it can be some communication tools like Slack, Zoom, Google Meet. They are particularly essential during the lockdown. 

Additionally, it would be a huge plus if a React Native developer is familiar with:

• Redux - to handle the mobile application state;
• Jest - JS code testing framework;
• Sentry - allows real-time crash checking;
• App Center - to build and distribute applications across testers;
• RNTL (React Native Testing Library) - to test RN components.
  

Certainly, there are many more such instruments that can streamline the developer’s work. Anyway, your potential React Native developer should be familiar with some of those tools. 

Code clarity and style

Working code doesn’t always mean a good code. Apart from functionality, the code should be clear. Clear code makes app maintenance and future updates a lot easier. Besides, it has a great impact on the functionality of the app. That’s because well-structured code is much easier to modify, understand and read. Basically, the ability to code with clarity is what separates pro devs from mediocre ones. Some techniques and principles help programmers make the code more understandable:

• SOLID;
• Command-query separation;
• High cohesion, loose coupling.
  

It would be nice to inform candidates in a vacancy description that you expect them to adhere to those principles and techniques. 

Another articulate sign of a good React developer is the ability to follow style guidelines. It is vital for teamwork. Consistent programming style allows developers to spot and fix bugs faster. A skilled React Native developer should be able to adjust to your project’s coding style.

Soft skills

As any other professional, React Native developers should have basic soft skills. Personal qualities influence teamwork productivity big time. Unlike the hard skills, some personal qualities of a candidate are up to you to rank. The choice should be based on your company’s culture and values. 

In this section, you’ll find several soft skills that impact React Native developer’s work the most.  

Communication skills 

The ability of a team member to exchange ideas and build trustworthy relationships with other developers is vital for effective cooperation. Therefore, the ideal candidate should have sufficient communication skills. Usually, socially effective people have some of the following traits:

Empathy

If a person can feel for others and have a genuine concern about peoples’ emotions and states, there’s a high probability he/she would be a good team player.

Manners

Basic understanding of etiquette and polite treatment.

Sociability

The ability and willingness to contact other people, build trust relationships, and exchange ideas.

Problem-solving

Successful React Native developers are always proactive and result-oriented people. These qualities help them find solutions to any problem that can pop up during the app development cycle. 

Time management

Time is the essence in mobile app development as the release date defines a great deal of its success. If the development company fails to meet deadlines, it can heavily damage its reputation. To set the precise release dates, companies create project time estimates. That’s why the time management skills of your React Native developers should be on a high level.  

Responsibility

Like for all professionals, this quality is essential for react developers too. Responsible people are more likely to get thighs done properly. Usually, such people are the leaders and serve as role models that set the productivity and quality bar of the team quite high. If you want to have a team member you can rely on, make sure your candidate is ready to take full responsibility for the work. 

Stress resistance

The world of software development is tough. Sometimes, the working pace of mobile apps development projects becomes insane. Apart from that, developers are always under pressure of high expectations and pretty tight deadlines. Needless to say, to withstand all these, they need to have iron nerves. You don’t want to lose a developer in the middle of the project because of nervous breakdown. So, you need to choose a pretty stress-tolerant person from the start.   

Creativity

App development is a sort of art. You can see the individuality in the way the elements of the application are organized. Most people can define the templated approach after a few minutes of using an app. Obviously, templated apps don’t strike the audience and are unlikely to catch the attention of millions. On the contrary, ingenious and bold solutions attract users and increase app engagement time.

Although creativity’s not a widespread quality, it is great to have a developer who can think outside the box in your team. 

How to write a React Native developer job description

Once you’ve figured out what skills and personal qualities you are looking for in a React Native developer, it’s time to write a job description. 

The vacancy description is the first conversation you have with your potential React Native developer. And, the first impression it will have on the seeker is the decisive one.
