This post will not only outline the challenges but also demonstrate how partnering with a seasoned agency like ours provides the strategic advantage needed to build a successful custom ReactJS application.

What is a ReactJS App?

Before diving into the challenges of development, it is essential to clarify what we mean by a “ReactJS app,” especially in the context of creating experiences that span beyond the traditional web browser. While React.js is famous for its role in building dynamic web user interfaces by manipulating the Document Object Model (DOM), its principles have been extended to create applications for mobile platforms.

In this context, a ReactJS app refers to a mobile application built using the React paradigm. However, it operates fundamentally differently from its web-based counterpart. Instead of relying on web-standard DOM components, these applications leverage native user interface elements—the very same building blocks used in traditional iOS and Android development. This approach allows for a truly native look, feel, and performance, which is critical for a high-quality mobile user experience.

The core challenge, and a recurring theme in development, is bridging the gap between the world of web development and the intricacies of mobile platforms. A developer working on these apps must be more than just a skilled JavaScript or React web developer; they must also understand the nuances of mobile UX, platform-specific UI patterns, and the underlying native components. Similarly, a traditional smartphone developer may not grasp the web-centric architecture and state management principles that React brings to the table. Therefore, a “ReactJS app” for mobile represents a powerful but complex synthesis of web and native technologies.

Reasons That It Is Difficult to Develop a ReactJS App In-House

While the promise of using a single framework to target multiple platforms is appealing, the reality of in-house development often reveals a steep and resource-intensive learning curve. The challenges are not merely technical; they span skill sets, project management, and long-term maintenance. Here are the primary reasons why building a custom ReactJS app in-house can be exceptionally difficult.

### The Challenge of Custom User Interface (UI) Development

One of the first hurdles teams encounter is UI development. Unlike some frameworks that provide a vast library of pre-built, off-the-shelf components, the React ecosystem for mobile often requires a more bespoke approach. While this allows for unparalleled customization and a unique brand identity, it also means that creating a polished, platform-consistent UI can take significantly more time and experience.

• Fewer Off-the-Shelf Options: Your team cannot simply pick from a ready-made catalog of components for every feature. This means that elements like complex navigation systems, custom animations, and unique interactive widgets must be built from the ground up.
• Requires Deep Experience: Crafting these custom components requires a developer who not only understands React but also has a deep appreciation for native platform conventions on both iOS and Android. Without this experience, the result can be an app that feels clunky, non-intuitive, or visually inconsistent, ultimately leading to a poor user experience.

### Navigating Performance Bottlenecks

Performance is paramount in mobile applications; users have little patience for slow-loading screens or jerky animations. Certain common features, such as long, scrollable lists of data, can present significant performance issues in ReactJS mobile apps.

• List Performance Issues: Infinite scroll lists, common in social media feeds and e-commerce apps, can become slow and unresponsive if not implemented correctly. While these performance issues are well-understood and manageable for seasoned developers, they can become a major roadblock for novices. A junior or mid-level developer might spend weeks debugging an issue that an expert could solve in a few hours.
• The Novice-Expert Gap: This gap in experience is critical. An in-house team without a senior expert in React performance optimization may struggle to diagnose and fix these problems, leading to project delays and a subpar final product.

### The Specialized Skillset Requirement

Successfully building a ReactJS app requires a unique blend of skills that is rare to find in a single developer, let alone an entire in-house team. A common misconception is that any JavaScript or web developer can easily transition to building these mobile apps. This is rarely the case.

• Beyond Web Development: Many talented React web developers are experts in the DOM and web-based UX, but they may not understand the subtleties of mobile design. Critical concepts like touch gestures, navigation patterns, screen transitions, and platform-specific UI guidelines are entirely different worlds.
• Beyond Mobile Development: Conversely, a traditional smartphone developer who is an expert in Swift or Kotlin might not fully grasp the web-centric paradigms that React introduces, such as state management and the component lifecycle.
• The Inadequacy of a Basic JS Developer: A generalist JavaScript developer without platform-specific experience is simply not equipped for the task. They lack the context for both the React architecture and the native mobile environment, making them inadequate for building a robust and scalable application.

### The Complexity of Native Component Integration

ReactJS mobile apps achieve their native performance and feel by using native components extensively. This is a major strength, but also a significant source of complexity and potential bugs.

• Unexpected Behavior: Because the app is a bridge between JavaScript code and the native platform UI, things may not always function as they should. A component might look or behave differently on an older Android device compared to the latest iPhone. Debugging these issues requires the ability to trace problems from the JavaScript layer down into the native code, a skill that requires deep expertise in all three environments.
• Bridging and Modules: Integrating custom native functionality—like accessing a specific hardware sensor or using a third-party native SDK—requires writing “bridge” code. This is a complex task that can introduce instability if not handled correctly.

### The Constant Burden of Updates and Compatibility

The mobile and JavaScript ecosystems are in a constant state of flux. This rapid pace of change creates a significant maintenance burden that can catch in-house teams off guard.

• Operating System Updates: A major OS update can introduce breaking changes. For instance, a past Android upgrade caused specific, hard-to-diagnose performance problems in some ReactJS apps. Your team must be prepared to react quickly to these external changes.
• Vendor and Dependency Updates: The functionality of an app can also be impacted by updates from hardware vendors or third-party libraries. A change in a dependency could introduce a bug or a compatibility issue.
• Framework Updates: Even ReactJS itself updates frequently. These updates can introduce disruptive changes, and compatibility issues may arise. Keeping the framework and its vast web of dependencies current is a challenging and time-consuming task that requires careful planning and rigorous testing.

### Severe Limitations in Code Sharing

A frequently cited benefit of cross-platform development is “write once, run anywhere.” However, the reality of code sharing between a React.js web application and a ReactJS mobile app is far more limited than many expect.

• DOM vs. Native Elements: The fundamental difference is that React.js for the web depends on DOM components (<div>, <span>, <p>), while ReactJS for mobile uses native elements (<View>, <Text>). This architectural divergence means you cannot simply reuse your UI code.
• What Can Be Reused?: In practice, the only code that can be seamlessly reused is business logic—non-DOM libraries and source code that handle data, state management, and API calls.
• Diminishing Returns: The effort required to abstract and modify code for reuse can sometimes be greater than the effort of creating new, optimized mobile logic from scratch. For many teams, attempting to maximize code sharing leads to overly complex, poorly performing applications. It is often more efficient to accept the limitation and build dedicated logic for the mobile experience.

Cost Estimate for Developing a ReactJS App

Determining a precise, one-size-fits-all cost for a custom ReactJS app is impossible without a detailed project scope. The final investment is directly influenced by the very challenges we have discussed throughout this article. Rather than a simple price tag, it is more productive to understand the factors that drive the cost.

The complexity of your application is the single largest determinant of cost. The key drivers include:

• Custom UI/UX Design: An app with a highly bespoke, animated, and intricate user interface will require significantly more development hours than an app that uses more standard, utilitarian components. The time and experience required for this custom work are a primary cost factor.
• Performance Optimization: If your app needs to handle large datasets, real-time updates, or complex animations smoothly, it will require senior developers with expertise in performance tuning. This specialized skill commands a higher investment but is critical for user retention.
• Native Feature Integration: The need to integrate with device hardware (like GPS, camera, or biometric sensors) or to incorporate third-party native SDKs adds complexity. Building and maintaining the “bridge” between JavaScript and native code requires specialized skills and adds to the overall cost.
• Backend and API Development: The cost is also heavily dependent on the backend infrastructure. A complex system with multiple user roles, data processing pipelines, and third-party API integrations will be more expensive to build and maintain than a simple content-driven app.
• Ongoing Maintenance: The development budget should also account for the ongoing cost of maintenance. As discussed, OS and framework updates will require regular attention from your development team to ensure the app remains functional, secure, and compatible.
