React Native is a technology where cross platform development has emerged and has been quite the choice of developers to develop native apps, whether cross compatibility on iOS or Android devices provides a platform specific user experience. The React Native Technology which was launched back in 2011 by Facebook still continues to be trending and will continue so, especially in the E-commerce domain category which allows for a simple and effective E-commerce store. The primary reason which E-commerce has adapted react native frameworks is its capability of providing reusability of code, compatibility with a host of third party tools, and has been used many of the popular and leading apps in their diverse sectors with the likes of Walmart, Flipkart, Microsoft One Drive and many more. Some key factors influencing Developers to select React Native platforms includes a vast community support, which helps new developers get their hands on, solutions that have been built and polished by experienced developers. With optimum code reusability, as much as 90% of the code can be reused for different platforms. Another advantage of React Native is the application reload on a live basis, which means that if the developer makes any changes in the code, the output can be reflected on the Output almost immediately. In terms of performance, for React Native GPU performance is utilized rather than the traditional CPU utilization which in turn benefits in faster loading speed and performance of the apps. The budget benefit also comes in since code reusability is a thing in for React Native Apps, efforts in development are saved thus reducing the overall budget for an E-commerce project bundled with a simple UI following an open source framework rather than a conventional one with support for modular architecture as well. But with the benefits there are certainly some downfalls for using this technology. First of all, this is a comparatively new programming language when compared to the Android or iOS counterparts and the learning curve for this programming language is on the difficult side. Even though in terms of performance the React Native is on par with other native apps, memory management and high initialization time is the cause of concern which makes the development a bit tedious. Looking at both sides of the coin, how effective is it to develop on React Native? Well, with features and benefits loaded, third party and public community support, E-commerce businesses can effectively build good apps with reduced costs and time. But the drawbacks would also need to be considered and would depend on the priority and feature inclusion in the apps, with requirements of advanced functionalities for development but there are great chances for the React Native Community to gain ground and then be the primary choice of developers for cross platform development.
