A calculator app demonstrating how to share code across iOS, Android, desktop (NW/Electron), and web using React Native and React.
react-native-nw-react-calculator is a demonstration project that builds a calculator app running on iOS, Android, desktop (via NW.js or Electron), and web browsers from a single codebase. It solves the problem of maintaining separate codebases for different platforms by sharing business logic and UI components through React Native and React.
Developers and teams building cross-platform applications who want to understand how to share code between mobile, desktop, and web using React and React Native.
It provides a concrete, working example of cross-platform architecture with shared Flux logic and platform-specific rendering, reducing duplication and simplifying testing across environments.

Implements a 100% shared Flux architecture for actions and stores, ensuring consistent logic and data management across iOS, Android, web, and desktop, as explicitly stated in the README.
Uses file naming conventions (e.g., .ios.js, .android.js) to separate render logic, allowing components to share base classes while adapting UI for native feel on each platform.
Leverages Webpack for hot reloading during development and Grunt for builds, facilitating faster iteration and testing across multiple environments.
Clearly documents component structure with base logic and separate render files, making it an effective learning resource for cross-platform React patterns.
Relies on older libraries like Flux and build tools like Grunt, which are less common in modern React ecosystems and may not support newer features like Hooks or Concurrent Mode.
Requires separate configurations for iOS, Android, NW.js, and Electron, with noted npm version issues and multiple installation steps, increasing initial setup time and potential errors.
Each component needs up to 6 files (e.g., Screen.js with multiple render files), which can lead to maintenance overhead and confusion in larger projects.
Admits in the README that features like isomorphic rendering are 'next' steps, indicating missing optimizations and lack of ongoing updates for real-world use.
