Share code between React Web & React Native Mobile with Nx

The article details the process of creating both a web and a mobile application using a monorepo setup with Nx, focusing on optimizing code sharing between a React web app and a React Native mobile app. The author, primarily a web developer, begins with the creation of a Studio Ghibli-themed search engine as a React web app and later develops a mobile version using React Native. While the UI components have to be rewritten due to React Native's use of native elements instead of web views, the article emphasizes the reuse of non-UI business logic through shared libraries for models, services, and the Redux store. It outlines specific challenges such as environment variables, routing, storage, and network requests, providing solutions for each to ensure compatibility between web and mobile platforms. The approach underscores the benefits of maintaining shared business logic to streamline maintenance and ensure feature consistency across both applications.
