Is React Native Still Relevant In 2022?

Technologies change every day and being a leading web and mobile app development company, we strive to employ the relevant and latest technology to be able to provide our clients with dynamic apps. Let's discuss how React Native is performing in 2022.

Introduction

The demand for cross-platform app development is increasing as we speak. The reasons behind this are well-founded in facts. Cross-platform apps not only reduce the costs and time of development but also prove to be the right tool to reach a larger audience compared to being present on just one platform. Amongst the other technologies, React Native has time and again proved its mettle when it comes to building robust cross-platform apps. It is also popular among developers as it allows for building apps with less code.
But, due to the rise of other frameworks, experts once again face the challenge of speculating React Native’s relevance and future in the coming times. In this article, we will analyze whether React Native is still a safe bet for developers.
Let’s begin.

What is React Native?

To start with, React Native is the open-source UI development framework that allows developers to build applications for Android, Android TV, iOS, macOS, tvOS, Web, Windows, and UWP using React framework along with native platform capabilities. It allows the same code to be reused to run on different platforms with minimal changes. This speeds up and enhances the efficiency of the development process.

What’s the latest in React Native?

Ever since its introduction, React Native has seen numerous updates and revisions that have only added to its robustness and reduced its API surface area to make it more lightweight. It is holding its position in cross-platform app development as always. A majority of tech giants use it for developing their apps.
The state of React Native app development in 2022 is backed by support tools added in the previous and current year and subsequent releases. They make it better for developers and businesses simultaneously. One of the most recent and pivotal changes that we saw lately was the update in its architecture.
React Native 0.69 just got announced with powerful new features such as React 18 support and bundled Hermes. It comes with React 18 enabled by default, new hooks such as useId, and new features such as useTransition or full Suspense support.
Earlier versions of React Native and Hermes came separately. This always raised confusion in identifying which version of React Native is compatible with which version of Hermes. React Native 0.69 comes with a compatible version of Hermes to address this issue and provide developers with a more streamlined and stable use of Hermes.

How does React Native work?

In older versions, the basic component of React Native used to be the Bridge. It is used to control all the communication between JavaScript and native components and vice versa. The bridge translates JavaScript code into platform-specific components. Although these async calls used to occur apart from the main thread, having multiple threads and large amounts of data could result in delays.
For example, when a user presses a button, the case is translated into an event for the JavaScript to understand. The bridge translates native events for React components to understand by communicating with native platforms and JavaScript code. This is an asynchronous way of relaying information.
However, the new architecture removes the need for a bridge. Instead of passing data over the bridge in an asynchronous manner, developers will have reference to C++ host objects, which can be called directly and get the response back synchronously. This is quite similar to how we get node references in ReactJS and perform actions on them.

What are the alternatives to React Native in 2022?

Although the architecture of React Native allows for code reusability, live-to reloads, third-party plugins, cost-efficiency, and a lot more, there are other frameworks that challenge its authority.

The top alternatives to React Native include:
Flutter

Flutter, just like React Native, is a cross-platform framework for developing striking user interfaces. The primary reasons why the Flutter community is gaining popularity every day remain the look and feel of the Flutter widgets for app creation and the absence of bridging required in the case of JavaScript. Since Flutter uses Dart as the programming language, the lack of bridging enhances its performance.

Xamarin

Xamarin is owned by Microsoft and uses .net and C# for cross-platform app development. It allows you to create an iPhone app on Windows and compile it on Mac. Only the build is platform-dependent. The look and feel of the app built using this will be completely native. The growing community and support available also make Xamarin a worthy opponent for React Native.

Nativescript

Nativescript uses JavaScript, Angular, VueJS, and TypeScript as the base languages for creating cross-platform apps. The reasons to choose Nativescipt over React Native might include the availability of hundreds of verified plugins and the ability to deliver fairly performance using web programming languages.

Is React Native still being used for native mobile app development?

Contrary to the belief that React Native is becoming obsolete, market trends indicate it is still being used for native mobile app development. As much as industry leaders like to invest in cross-platform apps, native apps still make a large chunk of the market share. React Native reduces the development cost and time for some components of a native app.

What is the future of React Native cross-platform development?

Experts predict that React Native will be relevant in future cross-platform app development. The reasons that support this speculation are as follows:

Backed by JavaScript

JavaScript is one of the most popular programming languages. React Native builds on this language, allowing developers to easily understand and create advanced applications. Even when clients need to switch to React Native from other platforms for mobile app development, the learning curve for javascript is not that steep for new developers.

Large community

Developers also prefer using this framework because of the large community where they can connect and find solutions to problems. There are constant upgrades and changes to help provide the support required. A community-driven approach to building agile apps is more preferred and sustainable than depending on other technologies such as Dart, with relatively smaller community support.

Third-party plugins

Building an app from scratch can be an expensive affair. Therefore, React Native offers a range of third-party plugins that help developers build apps, including JavaScript-based and native modules. These plugins help enhance the performance of an app by eradicating the need for certain web view functions.

Live reload

React Native's live reload capability enables you to interact with updates in real-time. While the app is loading, you can make code changes that will automatically cause a refresh of the app. To speed up the compilation, you can also reload a specific area of change.

Cost efficiency

Reusability of code also brings about reductions in the cost of app development. There is no need to hire more developers in different teams based on the platform. Also, the pre-built components further speed up the development process and reduce the project timeline.

Conclusion:

These were a few of the eminent qualities that, we believe, justify React Native’s ability to withstand competition from other technologies for a long time. Being a leading cross-platform app & Blockchain development company, GeekyAnts has been and will be utilizing the sturdy and ever-evolving framework of React Native for the foreseeable future. Our expert developers are well-versed in building React Native apps that help cater to client requirements and reach larger audiences.

ReactJs Developers: How Much Does It Cost To Hire One
When considering how much it will cost to hire a ReactJs developer, one must take into account several factors. First and foremost, one must consider the developer’s experience and the amount of time you wish them to devote to your project on an hourly basis. Another crucial factor to consider when calculating the overall cost of hiring a ReactJs developer is whether or not you will require them to work full-time on your project or if you would be satisfied with part-time work only from them. Pricing Factors That Affect The Cost The cost of hiring a ReactJs developer can vary depending on a number of factors, including their experience, the size and scope of your project, and whether or not you need them to work on-site. Here are some of the main pricing factors that will affect how much you pay for a ReactJs developer: -The developer's experience. A more experienced ReactJs developer will generally command a higher rate than someone who is just starting out. -The size and scope of your project. A larger, more complex project will require more time and effort from the developer, and thus will be more expensive. -Whether or not you need the developer to work on-site. Freelance vs. Agency Developers The cost of hiring a ReactJs developer can vary depending on whether you hire a freelance developer or an agency. A freelancer typically charges by the hour, while agencies often charge a flat rate per project and some may offer retainer contracts for ongoing work. When it comes to freelance developers, it’s also important to understand how much experience they have with working with ReactJs as that will impact their hourly rate. For example, someone who has worked in front-end development for over five years and is experienced with ReactJs might charge $150-$200 per hour whereas someone who is just starting out might charge around $40-$60 per hour. Contractors vs. Full-Time Employee Costs The cost of hiring a ReactJs developer depends on whether you want to hire a contractor or a full-time employee. If you're looking for a one-time project, it's usually cheaper to hire a contractor. On the other hand, if you're looking for someone to work on an ongoing basis, it's usually cheaper to hire a full-time employee. The average hourly rate for a ReactJs contractor is $50-$100/hour. The average hourly rate for a full-time ReactJs employee is $30-$50/hour. When you hire a full-time employee, there are also additional costs like taxes and benefits that you have to pay. However, when you hire a contractor, these additional costs don't apply. How Long Does It Take to Develop An App? Assuming you're starting from scratch, it will take at least six to eight weeks to develop a minimum viable product (MVP). This MVP will have the core features of your app and will be able to be used by early adopters and beta testers. From there, you can iterate and add new features as needed. The whole process can take anywhere from a few months to over a year, depending on the complexity of the app. This is just an estimate; some companies may need less time while others may need more. There are many factors that contribute to this timeframe, including the number of people working on the project, availability of the developer(s), their level of expertise in ReactJS development, and whether or not they have previously worked with any similar projects before. But What About Pricing? In general, most ReactJS developers charge between $40-$120 per hour for development work, but this is dependent on how much experience they have in general as well as how experienced they are with ReactJS specifically. What Are Development Platforms for React Applications Like? It is often used with React Native, a platform for building native mobile applications using JavaScript. When it comes to development platforms, React developers have a few options. The most popular are probably create-react-app and React-create-app. These two platforms allow developers to quickly create and test React applications without having to set up a development environment. Other popular options include Next.js and GatsbyJS. Next.js is a framework that allows you to use server-side rendering of React components, which means that the pages load faster because the browser doesn't need to fetch JavaScript and HTML separately before rendering the page. When Do You Need a New Version of the App Built? If you're considering hiring a ReactJS developer, one of the first questions you'll need to answer is how often you'll need a new version of the app built. If you plan on making changes or adding features regularly, then you'll need to find a developer who is available on an ongoing basis. However, if your app is relatively static, then you may only need to hire a developer for a one-time project. What Type of App Do do You Want to Build?: Next, you'll want to decide what type of app you want to build. Apps can be either mobile apps or web apps (a.k.a., a website). Mobile apps are usually more expensive because they require different coding languages and programming languages than web apps do, as well as testing before release (e.g., Apple's TestFlight). What If Your Application Is Very Large? If your application is very large, you may need to hire a team of ReactJS developers. The cost to hire ReactJs developers of hiring a team will depend on the size of the team and the experience of the developers. Generally, the larger the team, the more expensive it will be. Also, if you require a lot of custom work or features, you may need to pay more. In general, you can expect to spend at least $20 per hour for an experienced developer. However, they are worth every penny!
How to Create a Successful Custom Web Product Step by Step: Codica's Practice
The article was initially published in the Codica blog. When creating a winning web product, the team must follow the best practices and certain steps for development. This is how Codica ensures building top-quality websites. This article is a complete guide that shows the approach at Codica to creating web products that users enjoy. What methodologies are commonly used for project development at Codica? Today, custom software product development mainly relies on two methodologies, waterfall and agile. Both of them are useful and have their peculiarities. The waterfall methodology implies that the next stage of software development starts after finishing the previous one. So, the design of the web product starts only after the product discovery step is finished. Meanwhile, agile methodology means moving in small steps and applying changes whenever they are needed. This iterative approach offers more flexibility and mitigates risks early. At Codica, we rely on the agile methodology appreciating iteration as its main advantage. We hold daily, and weekly meetings to discuss the results achieved, further goals, and expected deliverables. What is the Codica team involved in the development process? The development process requires several careful steps, from assessing the business idea through development and finishing with quality assurance and support. These steps require certain professional roles. They are as follows: - Project managers (PMs); - UX/UI designers; - Frontend and backend developers; - DevOps engineers; - Quality assurance specialists (QAs). Working together, they follow the main steps to create functional and secure solutions. Let’s discover what these steps are. What are the 5 main steps that Codica follows in software development? Step 1. Product discovery sessions Product discovery is a preliminary step when we discuss the business and technical aspects of the client’s idea. This process involves stakeholders on the client’s side, a UI/UX designer, a tech lead, and a project manager. The result of the product discovery process is the specification document and project estimate that a designer, tech lead, and project manager create together. Also, they create prototypes, a roadmap, and a process diagram and show all these documents to the client for discussion. Below is an image illustration of the main tasks we complete during the project discovery phase. After the discussion and approval of the project documents from the client, our team proceeds to design and develop the project. Step 2. Skillful designing At Codica, we create designs for each product regarding the outcome and deliverables from the discovery session. Our designers consider the style of a web product and the appearance of UI elements and font hierarchy. For example, below is a design that our team created for a kids' activities marketplace. Also, designers create a guide on the website design that is used by developers and quality assurance engineers. By the way, you can see attractive and user-friendly designs we created on our Behance profile. Step 3. Web product development After all preparations, our team starts the development process. Typically, we recommend our clients create their product as a minimum viable product (MVP). It is a primary workable version of the product that includes basic features and can be launched to the market. It is useful because you can see how users try and accept your product with the least effort for development. The development at Codica includes several phases. Let’s discover what they are. Preparations for the development Starting with the inception phase. The inception phase means planning and allocating roles for the development. An entire team takes part in this stage. It involves discussions of the specifications and prototypes created in previous stages. Also, the stage includes assessing the risks and difficulties of product release. Creating the product backlog. A project manager creates a backlog in Jira, a collaboration tool. The backlog includes epics, which are milestones for each set of features to be developed. The epics constitute the roadmap that helps developers move through the development process. Building a staging environment. Creating a code takes small steps as we follow agile methodology. Every part of the code that we create undergoes testing with Gitlab CI/CD (Continuous Integration/Continuous Delivery), a tool that automates development processes. Both staging and prod environments are created and managed by our DevOps engineers. Also, DevOps help to host a product properly. We prefer Amazon Web Services (AWS) for this. It is flexible and has a rich set of features that ensure the secure and stable work of a website. Our iterative software development process While building a web product, developers and quality assurance engineers check the code logic and the code compliance with syntactic norms. We also check the code for vulnerabilities, and stylistic errors, run tests and deploy our code to test servers. Then a tech lead verifies the completed code. These operations are conducted in the staging environment and are a must before deploying the product on the prod. Step 4. Testing In parallel with designing and developing, we perform testing. So, quality assurance engineers (QAs) start testing the code from the moment when they receive specifications from a project manager after the discovery sessions. QAs clarify the details of how the product must look and function and write these nuances in the Acceptance Criteria document. Also, QAs use the following documents: - Checklists that present the compliance criteria for the code; - Test cases that are a complete description of test scenarios with steps and prerequisites. After all necessary checks of the code on stage as part of development, QAs perform regression tests. Such tests clarify that changes made to the code during development do not break the code structure. So, regression testing is an initial check of the product as a whole. After the checks are completed, the project goes to the prod environment. Thus, QAs check the code on the prod once more. For example, as a result of development and thorough testing, we created an online travel marketplace that helped our client to double their expected sales. Step 5. Maintenance and support As new features appear and technologies evolve, we help our clients keep their websites up-to-date. So, our designers, developers, DevOps, and QAs make the relevant changes to keep web solutions running. The maintenance and support involve the following services that we offer at Codica: - Ongoing support, system maintenance, bug fixes, backup, and monitoring; - Improvement and updating of applications/systems, integration of new functions; - Redesigning software solutions to meet business requirements and conditions; Product technical support. We have a stack of tools that help us monitor the solutions and receive the metrics and alerts. They are as follows: - Prometheus; - PagerDuty; - Grafana. Conclusion When creating web products, we rely on the best software development practices. Following the five crucial steps, our web projects help our clients grow their businesses. If you need a website or want to test your business idea, contact us. Our experts are eager to help you.
