React Native App Development: From Idea to Success

Mobile apps have become an integral part of our lives. Millions of apps are available on the Google Play Store and Apple App Store for various purposes.

Whether you want to play a game, shop online, communicate with your loved ones, or check your financial portfolio, there is an app for you. A business mobile app can open a door for various opportunities and possibilities. Let's check out some statistics about mobile apps.

This is the best time to launch your mobile app. You can go either for native or cross-platform app development. Mostly, startups prefer cross-platform app development because of budget constraints. Also, cross-platform apps take less time to develop and offer a native-like user experience to users.

Regarding cross-platform app development, React Native is the first choice among developers. Owned by Facebook, React Native is an open-source, JavaScript cross-platform app development framework. Developers can create stunning UIs for mobile and web applications.

React Native developers mostly use native components and APIs to create highly responsive and smooth user interfaces. React, a JavaScript library, helps developers build interfaces that load quickly, offering a highly satisfying user experience. Native components help the app to render and execute code faster.

React Native app development is cost-effective and does not take much time. Thanks to extensive community support and several libraries and tools, developers can build feature-rich, scalable, and secure mobile apps with React Native.

The app development process with React Native is smooth sailing for developers. Features like Code Reusability help developers to use the same codebase for Android and iOS platforms.

You will need a team of experienced React Native developers with a proven track record in the domain. Expert developers with a thorough understanding of the framework and programming languages like JavaScript will help speed up the app development.

We will discuss the React Native app development process in detail, from idea to implementation, in this post.

Conceptualizing Your App

A good, feasible idea is the first fundamental requirement for any mobile app development process. You need to have a unique idea that addresses the concerns of your target audience. A potential idea uniquely identifies people's pain points and offers the right, convenient solutions.

For example, a personal budget app helps people manage their finances and budgets with a perfect bifurcation of bills, investments, incomes, and other aspects.

Defining the App Idea

All successful apps were ideas once. Potential ideas can turn owners' fortunes and help them address the issues their target audience faces. Instagram was conceptualized to allow users to post their personal stories through photos and videos. Similarly, WhatsApp was conceptualized to help people communicate smartly and flawlessly with their friends and family members.

However, defining the idea is what you need to understand whether the idea is commercially feasible or not. Putting the idea on paper is crucial to understand its feasibility.

This process is also called a Product Requirement Document (PRD). Here, you must write down everything you foresee about the idea, including your vision, purpose, specifications, features, and other aspects. A PRD will help the development team to understand your business requirements, needs, and other elements.

Market Research and Validation

The 2nd step is to understand the market.

• Is your app needed?
• Is there any similar app in the market?
• If yes, what are the features of the app?
• Who are your competitors?
• Can you identify the gap that your idea can fill in?
• How is the design of the app?
• What is the target audience of the app?
• How will you monetize the app?

These questions help you understand the latest market trends, competition, and opportunities. Most React Native app development companies prefer market research before developing.

Also, it is vital to study the prevalent consumer trends, market segment forecast research, and other crucial market research aspects.

Identifying Target Audience and Platform

If you want to address your target audience, you first need to know who your target audience is.

Do you have it?

If not, you need to find it.

There are various things that you need to know about your target audience, such as:

• Demographics
• Location
• Age
• Gender
• Occupation
• Education
• Interests
• Behavior
• User personas
• B2B or B2C (corporate or individual)

Sometimes, you might need to hire a market research agency to conduct in-depth research to identify your audience accurately.

Once you know your target audience, the next step is to discover the challenges they face. Also, you need to find incentives to help attract your users to use the app.

Also, knowing which platform your target audience uses will help you choose the right platform for your mobile app. Mostly, you will choose Android, iOS, or both (cross-platform app development) or the web.

The React Native Github repository allows developers to find source code for the framework. Furthermore, you can also join React Native community events to meet new developers and share knowledge.

React Native Architecture

Before proceeding further, we need to understand React Native architecture to learn how it works.

Understanding React Native Architecture:

Recently, React Native launched a new mobile app development architecture. The old React Native architecture had some performance and flexibility flaws addressed in the new one.

The old architecture had three threads: JavaScript, Main, and Shadow Thread. The main issue with the architecture was communication between these three threads.

The dependence on asynchronous JSON threads through the bridge was the biggest hurdle. The communication issue between these threads was causing unnecessary delays, uncertainty, and other issues.

The new React Native architecture has a set of tools, libraries, and features to build scalable apps. The new architecture perfectly addresses the issues of the old architecture. 

#1. JavaScript Interface (JSI)

The JavaScript Interface is fundamental to the new React Native architecture. It is an API powered with C++ programming language that interacts with any JS engine. Unlike the asynchronous bridge of the old architecture, the JavaScript Interface is highly synchronous to invoke native functions quickly.

The JSI removes the asynchronous communication between JavaScript and native components. It also allows JS to hold references to C++ host objects.

#2. Fabric

Fabric is a replacement for the older legacy rendering system. The main aim of introducing Fabric is to improve communication, performance, and interoperability with host platforms. This new render system uses asynchronous rendering and a new algorithm to improve the app's performance. It also takes less time to update the UI. Developers also find it easy to handle with advanced animations and interactions. Moreover, it is smooth sailing for developers to implement Fabric for server-side rendering for React Native.

Fabric is still under development. However, we can bet on it as it shows fascinating results in performance and inoperability.

#3. Turbo Modules

Developers can use Turbo Modules in React Native app development to start the app quickly. Turbo Modules are new Native modules that eliminate the loading problems with lazy loading modules. Turbo Modules allow bypassing the JavaScript bridge and communicating directly with the native modules.

Turbo Modules are type-safe. You can rest assured that the data from the module is accurate and correct. You can mitigate the number of bugs in the app.

#4. Codegen

Do you want to eliminate the task of writing repetitive code? Codegen is specially designed for you. Codegen invokes automatically when the app development process starts every time for Android and iOS development.

Codegen scripts are located in the React Native NPM package. It is also under development, and developers are working on possibly automating the compatibility between JavaScript and Native. Codegen also guarantees type-safety and compile-type safety. With Codegen, developers can have far simpler code and quick execution.

#5. Redux

Developers can use Redux for app state management. It is a state management library where you can store the state you want to use throughout the app development process. In addition to that, developers can use Redux with any JavaScript library and framework.

Developers need to install Redux and React-Redux packages to use this phenomenal library. With Redux, you can have an app that flawlessly and consistently runs across various environments. React Native has developed the Redux toolkit called Modern Redux, which allows developers to learn and write Redux logic meaningfully.

Threads in React Native

When you open a React Native app, the device will start three main threads. Also, there will be some additional background threads as per the needs.

#1. Main Thread:

The application will run on the main thread. This primary thread is responsible for various tasks like user interactions, UI rendering, etc.

#2. JavaScript Thread:

The JavaScript thread is responsible for the execution of the business logic of the application (JavaScript and React code).

#3. Shadow Thread:

The device will launch a Shadow thread with a JavaScript thread. The main task of this thread is to compute the view positions and the tree layout construction coded in the JS thread. Yoga is a layout engine that React Native uses to convert flexbox-based layout into a native host-friendly layout system.

#4. Native Modules Thread:

This thread will be launched when the app needs access to a platform API like camera, location, etc.

Realms in React Native

There are two realms in React Native called JavaScript Realm and Native Realm.

#1. JavaScript Realm

The JavaScript Realm is where developers program the React Native app in JavaScript. Here, the code runs on a JavaScript engine called JSCore.

#2. Native Realm

Here, developers write code with platform-specific languages like Objectove-C and Java. In this realm, the main UI thread can create background threads if needed.

React Native Components and Navigation

The best thing about React Native is that developers can write the UI code with JavaScript instead of Kotlin and Swift. To invoke native views, developers can use core and native components.

#1. Hooks and Functional Components

Hooks replaced all the class component use cases in 2019. Furthermore, significant React Native libraries like React Navigation 5.0 and React Redux 7.1.0 support Hooks. With Hooks, developers can easily split components into smaller functions. Also, developers can manage the component's local state with a reducer.

#2. Core Components and Native Components

In React Native app development, you will need advanced features like tab navigation and others to offer a native-like user experience to users. Mostly, developers use a JavaScript library called React Navigation for app navigation pattern implementation. This library comprises multiple native libraries like Reanimated, Gesture Handler, etc.

Also, React Navigation helps developers to structure and navigate the app screens.

#3. Referential Transparency and Static Type Checking

React Native app development is based on functional programming, though JavaScript supports functional and object-oriented programming.

React, a JavaScript library used in React Native app development ensures that all components written by multiple people work excellently together. If the input is kept the same, you will get the same output with React.

Developers also use static type checking and unit testing for transparency. This is done by using tools like TypeScript and ESLint.

#4. Wrapping Dependencies

Third-party libraries used by developers help to simplify the app development process. However, sometimes, these libraries need to provide advanced features and functionalities. Switching from one library to another will add up costs in such scenarios. You can use the wrapping philosophy here by wrapping the API around libraries. One thing that you should consider is ensuring platform portability while using the wrapping libraries with custom APIs.

#5. Reanimated 2

Animations make the app look impressive and immersive. React Native developers use Reanimated 2, a JavaScript library, to build highly functional animations for the app. As it runs on the UI thread, you can develop animations even when the app is busy. The library comprises many hooks and functions to write clean code. Beautiful and creative animations can improve user engagement and experience.

Designing of the React Native App

UI/UX Design Principles for React Native

Developments must follow UI/UX design principles to ensure highly immersive and impressive app design. Some principles are discussed here:

#1. Native look and feel:

Make sure that the app looks and feels like a native app. Developers must follow all the platform-specific UI/UX design principles and use the UI components to offer a seamless, native-like user experience.

#2. Performance:

Developers must write clean code to ensure top-notch app performance. The app must be fast and highly responsive. Avoid adding unnecessary animations and features that might clutter the app.

#3. Accessibility:

Design the app in a manner that everyone should access the app, including people with disabilities. Carefully read and follow accessibility guidelines and add alternative text for images to ensure high-end accessibility. Test the app thoroughly on different devices to ensure accessibility.

#4. Usability:

Developers must design the app to ensure high-end usability and navigation. Avoid complex interactions to keep the navigation smooth and user-friendly. Getting user feedback can help identify and fix usability issues.

#5. Visual Hierarchy:

The app must have a clear visual hierarchy by using various fonts, colors, and animations that clearly define the most critical elements of the app.

#6. Consistency:

The app should be consistent in design and not cluttered and disoriented. Developers must use the same UI components and design patterns to ensure a good level of consistency. Using a component library can help developers create a highly consistent design.

Creating a User-Friendly Interface

The user interface is the first element users will notice while opening the app. Your app's UI will determine the app's success. You have to follow a zero-compromise policy on UI to ensure high user engagement. Make sure that the UI is consistent, impressive, and user-friendly. Here are some tips to create a user-friendly UI.

• Keep the UI simple, clean, and uncluttered to ensure maximum engagement.
• Go for a consistent typeface, style, font sizes, colors, and layouts throughout the app.
• Reduce cognitive load on the app to improve the loading time.
• Test the app with real users to get their valuable feedback and use this feedback to improve the UI.
• Research user preferences, personas, and interests to create user-centric UIs.
• Keep the language of the app simple and easy to comprehend.
• Use typography to add some visual richness to the app. It also helps to create an app with smooth navigation.
• Also, you can use images and videos to keep the UI exciting and engaging. Try to tell a story through images and videos to engage your users instantly.

Ensuring App Security and Data Protection

It depends on the expertise of the React Native developers to kickstart the project. For example, if you are new to cross-platform app development, you should go with Expo Go, a framework with a wide range of tools and services to build React Native apps. With Expo Go, you can start developing a React Native app quickly. All you need is the latest Node.JS version and a phone or emulator. Also, you can try Snuck, another React Native tool if you want to start React Native directly in your browser.

If you have hired a reputed React Native app development company, you can go for React Native CLI. You will require Xcode or Android Studio to start the project with React Native CLI. Installing these tools will take an hour or two to get you started.

#2. Implementing MVVM architecture in React Native

If you are familiar with mobile app development, you must have heard of the MVVM architectural pattern. It is mostly used to build highly impressive user interfaces. This three-layer architecture (Model-View-ViewModel) can separate the UI, the data, and the logic. It makes the code easy to maintain and access.

For the implementation of MVVM in the project, you will need to create three components, one for each layer. The View component will render the user interface. The Model component will store and manage data and the ViewModel component will become an intermediary between the View and the Model components. It will first receive data from the Model component and expose this received data to the View. Also, the MVVM component will take care of user interactions and model updates.

#3. Utilizing React Native Components and Libraries

React Native components and libraries are bliss for developers. These components can speed up the development process and build highly consistent applications. However, developers must ensure they choose the right components and libraries for the project.

Let's Check Out Some Essential React Native Components and Libraries in Brief:

React Native Elements: This library has 200+ components to be used by developers. All these components follow the guidelines of Google's Material Design.

NativeBase: if the developer wants to build Android and iOS applications, this library can be helpful as it is based on Android and iOS principles.

React Native UI Kitten: It has 40+ components designed to make the app immersive, beautiful, and attractive.

Apart from component libraries, developers can also use various other libraries in the development process. The React Native Vector Icons library has 1,000+ icons that developers can use in the application.

Here is a list of things to keep in mind while using React Native components and libraries:

Carefully use the libraries and components according to the project's needs.

Always use current libraries and components to avoid bugs and security vulnerabilities.

Each component and library has its own documentation. Read it carefully to understand how to use it perfectly and accurately.

#4. Integrating Firebase for Backend Services

React Native developers use Firebase for backend services to add advanced functionalities, such as real-time database, authentication, etc. You will need an experienced React Native developer to integrate Firebase into the app.

Also, while integrating Firebase, you must remember to handle error cases. Also, the developer must follow the documentation to implement specific services. Securing Firebase credentials is also equally important to mitigate security risks. You can visit https://firebase.google.com/docs to learn more about Firebase and access documentation.

Firebase allows developers to add compelling features to the app without building them from scratch. It saves the time and effort of developers and helps them create robust apps.

#5. Ensuring Cross-Platform Compatibility with React Native for Web
