Our Own React Global State Manager in Less Than 50 Lines of Code

You can create a global state manager in React using React context in under 50 lines of code. This approach is dependency-free and has minimal transfer size. However, it may have performance issues with renders and is tied to React, making stores React-specific.

Redux Saga is a tool for managing side effects in Redux applications. While it offers powerful capabilities, it can become complex and time-consuming to manage, potentially leading to late nights debugging or implementing features.

Alternatives to Redux for state management in React apps include React context, Zustand, and custom hooks. These solutions can offer simpler implementations with fewer dependencies or boilerplate, and they are not necessarily tied to React.

The proposed global state manager is implemented in a simple and lightweight manner using hooks and vanilla JavaScript. It avoids the complexity and boilerplate associated with Redux, and does not rely on context or providers.

useSyncExternalStore is a React hook that allows you to subscribe to external state changes. It is used to manage global state by subscribing to changes and updating components accordingly without relying on context or providers.

Zustand is favored for its simplicity, ease of use, and the fact that it is not tied strictly to React, allowing flexibility in how it is used across JavaScript applications. It also provides a clear API and efficient state management.

Performance can be optimized by using selectors to subscribe only to specific parts of the state that components need, thus reducing unnecessary re-renders.

Yes, it is possible to use a custom hook for state management without providers in React by using vanilla JavaScript and the useSyncExternalStore hook, which allows components to subscribe to external state changes directly.

The 50-line global state manager solution may lack features such as deep checking of object differences and debugging tools. It is also not a production-ready solution, but rather a simple demonstration of managing state with minimal code.

Creating a custom global state manager provides a lightweight and flexible solution tailored to specific needs, with minimal dependencies and boilerplate, while offering a deeper understanding of state management principles.
