How to manage global state in React?

There are multiple ways to manage global state in React, depending on the complexity of your application and your specific needs. Here are some common approaches:

  1. Context API: React's Context API allows you to share data between components without having to pass props down manually at every level. You can create a context that holds your global state and provide it to all the components that need access to it.

  2. Redux: Redux is a popular state management library for React that helps you keep all of your application's state in a single, central store. Redux provides a predictable and transparent way to manage state changes, and it works well for larger applications with complex state management needs.

  3. useState and useEffect hooks: If your global state is fairly simple and doesn't need to be shared across multiple components, you can use the useState and useEffect hooks provided by React to manage state at the component level. You can lift state up to a common ancestor component and pass it down to child components as props.

  4. React Query: React Query is a library that provides tools for managing and caching remote data in React applications. It can be used to manage global state that is fetched from an API and needs to be shared across multiple components.

  5. MobX: MobX is another state management library for React that allows you to create observable state objects that can be automatically tracked and updated. MobX works well for applications that have a lot of reactivity and need to update state frequently.

Ultimately, the best approach for managing global state in your React application will depend on your specific requirements and the complexity of your application. It's important to carefully consider your options and choose a solution that best fits your needs.
