What is React Native?

React Native is an open-source framework for building mobile applications.

It was developed by Facebook as a tech stack to help build cross-platform mobile apps using JavaScript and the React library.

The main idea behind React Native is to enable developers to write code once and deploy it on multiple operating systems.

This is achieved through the use of a single codebase written in JavaScript, which is then translated into native code for each platform.

It uses native components instead of web components to provide a native look and feel for the apps, ensuring better performance and user experience.

React Native Basics

The basics of React Native involve having a detailed knowledge of its architecture, understanding that it varies with traditional app development, and how it works.

Let’s delve into its intricacy.

React Native Architecture

Its architecture has only three distinct layers, there are its JavaScript layer, the Bridge layer, and the Native layer.

  • JavaScript Layer

It consists of the logic of the application that’s written in JavaScript. Here, programmers write codes to create UI components for features.

  • Bridge Layer

This connects the JavaScript code with the native code, allowing communication between the native modules and the JavaScript layer.

  • Native Layer

This layer has platform-specific codes that are written in a suitable mobile app language. It offers access to the device’s native APIs and renders the User Interface components.

  • Here, developers write a single codebase in JavaScript which can be used to create Android and iOS platforms.
  • This codebase significantly reduces development time, maintenance, and effort.
  • Traditional app development entails using separate codebases for Android, and another for iOS.
  • Developers write Java/Kotlin code for Android and Swift/Object-C code for iOS.
  • This codebase requires more time, effort, and maintenance.

How React Native Works

React Native uses a “virtual DOM” concept similar to React on the web.

Here’s an overview of how it works:

  • The developer writes code in JavaScript using React and the React Native framework.
  • When the app is launched, the JavaScript code runs on a JavaScript thread called “JS runtime.”
  • The code communicates with the Native modules through the bridge layer, sending and receiving updates.
  • The Native modules interpret the JS instructions and execute platform-specific code.
  • The Native modules also handle rendering the UI components on the device’s screen using native APIs.
  • The UI components receive updates from the JavaScript code and re-render accordingly.

Pros and Cons of React Native

React Native is a tech stack with numerous pros and cons.

For example, ReaThese pros and cons are key to determining whether to use the technology or not. As such, we’ll educate you on that.

Benefits of React Native

Let’s first consider the advantages.

1. Cross-Platform Development

A major advantage of using React Native is its ability to facilitate cross-platform development.

Cross-platform refers to the process of creating mobile applications that can run on multiple sites, such as Android and iOS with a single codebase.

The React Native Android studio allows you to tailor the solution for an immersive experience on the Android operating system.

The core logic and components of the application can be shared between both iOS and Android.

Also, its hot reloading feature guarantees developers a codebase that’s quickly executed, similar to what’s obtainable in a native solution.

2. Code Reusability

React Native has a component-based architecture, where user interface elements are created with reusable components.

Developers can compose and reuse their codes throughout the application.

Once a code is created, you can then reuse then in different parts of the application, even for another project.

This approach is what makes React Native known for code reusability.

3. Fast Development

React Native’s code reusability leads to quick development time.

By writing a single codebase in JavaScript, programmers reuse a significant portion of another aspect of the app.

Thereby, eliminating the time expended on writing codes to create new functionalities.

4. Native User Experience

The tech stack uses native components provided by the platform to render the user interface.

These components are genuine, platform-specific UI components.

For example, React Native uses UIView components on iOS, while it uses Android View components for Android apps.

Also, developers can access the device’s native APIs directly from JavaScript.

It offers a bridge that passes information between JavaScript and the underlying native codebase.

5. Cost Effectiveness

React Native is cost-effective due to its ability to deploy a single code on both iOS and Android.

With a single codebase, you’re saving time and resources to eliminate the need to create separate applications for each operating system.

This way, you don’t have to hire platform-specific programmers.

Also, React Native offers access to open-source libraries and resources, further reducing development costs.

This picture illustrates the benefits of using React Native for mobile app development

Not that we’ve talked about the advantages, how about the disadvantages?

Drawbacks of React Native

As popular and helpful as react native is, it has its own disadvantages.

These include:

1. Limited Access to Device Functionality

Although React Native offers a bridge to access the device functionalities and native APIs, it doesn’t offer access to every range of native features.

Also, developers have to write platform-specific code to achieve platform-specific UI elements.

2. Performance Issues

React Native does not match the performance of a fully native application.

Because the abstraction layer that bridges the JavaScript code and native platform can result in a slight performance lag compared to direct native code execution.

3. Debugging

Using React Native can introduce a number of challenges when it comes to debugging layout and styling issues.

React Native has some platform-specific variations in how components are rendered.

These result in layout discrepancies that are challenging to debug because they require platform-based adjustments.

Now that you know the advantages and disadvantages of this tech stack, when do you use them?

When to Use React Native

React Native is currently being used by over 40% of cross-platform apps, and the primary reasons for this large patronage are:

1. You Have a Product and Website Isn’t Enough

Statistics suggest that 85% of consumers prefer the app to mobile sites.

This is primarily because they guarantee better user experience, and often lead to a high user retention rate for business.

So, if you feel your website’s performance is limited, you can build a React Native app.

It guarantees better performance by rendering UI components directly on the device.

This results in smoother animations, faster load times, and overall better user experience.

2. Expand Availability by Entering New Markets

React Native allows you to write code once and deploy it on both iOS and Android platforms.

This means it allows you to target the two most prominent mobile operating systems with a single codebase, helping you save on development time and resources.

3. Building Large-Scale Applications

React Native lets you reuse code between platforms, which can be an advantage for large-scale apps.

By sharing a significant portion of your codebase, you can reduce development efforts and ensure consistency across different platforms.

This approach promotes code maintainability and simplifies the process of adding new features or making updates.

This makes it easier to manage and scale a large application.

Also, React Native encourages a modular approach to development, which ensures that you break your application into smaller, reusable components.

These are necessary for better code organization and ease of maintenance.

4. Limited Budget

React Native’s hot-reloading feature lets programmers observe real-time changes as they work on the code.

This improves the development timeline as it allows for rapid iterations, which can save costs associated with prolonged development cycles, and expedits time-to-market.

Also, if your company already has a solution created in React Native, you can reuse parts of the codes in your new project for similar features.

5. Leveraging Developer Expertise

React Native should be your preferred development tech stack if your product requires a large pool of programmers.

When you choose React Native, you have a better chance of finding lots of skilled developers with the expertise.
