Cross-Platform Mobile App Development Using React Native

Cross-platform mobile application development has emerged as a critical solution to the fragmentation problem in the mobile ecosystem, where applications must function seamlessly across multiple platforms with varying operating systems and hardware configurations. This research paper presents a comprehensive analysis of React Native as a viable framework for cross-platform mobile development. Through systematic review of technical documentation, comparative analysis with competing frameworks, case studies of industry implementations, and performance evaluations, this paper demonstrates that React Native provides a pragmatic balance between development efficiency and application performance. The research identifies React Native’s architectural strengths, particularly its native component rendering and the newly introduced Fabric architecture with TurboModules, while acknowledging performance limitations in computationally intensive operations. Key findings indicate that React Native reduces development time by 30-40% compared to native development through code reusability, maintains satisfactory performance metrics for most application categories, and benefits from a mature ecosystem supported by Meta and the JavaScript community. However, the framework exhibits challenges in handling complex animations, real-time graphics processing, and platform-specific native module integration. This paper concludes that React Native represents an optimal choice for rapid cross-platform deployment in most business scenarios, though native development remains preferable for performance-critical applications requiring intensive graphics or real-time processing.
