1. Using React Context API for User State Management

In this blog post, the topic explains how the React Context API can be used to manage global state within an application, especially for user authentication data (e.g., email, role).
• What is React Context API?
• React Context is a way to manage and share state across multiple components without having to pass props down manually at every level. It helps in handling shared states like user authentication or theme preference across an entire application.
• Implementation in the Project:
• In the mini project, the UserContext is created using createContext(). This context holds the user’s state, such as email and role (Admin/Viewer).
• useContext is used in different components (e.g., Dashboard, ManageItems) to access and modify user-related data.
• The login() function updates the user state with the login details, and the logout() function clears the state, effectively logging the user out.
• This approach makes it easier to access user data anywhere in the app, ensuring that only authorized users (Admin) can access restricted features.
• Why use React Context?
• It avoids “prop drilling” (passing props through many levels of components).
• Makes state management simpler and more maintainable.
