React Context API provides a way to share data across components without passing props down through every level, eliminating prop drilling and creating clean global state management. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented Context API in thousands of React applications for theme management, user authentication, and global application state. From my expertise, the most effective approach is creating context with custom providers and hooks for type-safe consumption and optimal performance. This method provides clean global state access with efficient re-rendering and maintainable code architecture.
