Well, an application has its state, which can be a combination of the states of its internal components.
State Management in Applications: Applications have their state, which can be a combination of the states of various internal components. For example, in an e-commerce website, components like the cart, user profile, and previously viewed sections each have their own states.
Example with Cart Component: Let's focus on the cart component. Its state includes all items the user has added and the total number of those items. The cart component needs to show the updated number of items in the user's cart at all times while the application is running.
Handling User Actions: When a user adds or removes an item from the cart, the application must handle these actions internally by updating the cart object's state. It also needs to reflect these changes in the UI by showing the updated total number of items in the cart.
Sharing State Between Components: As applications grow, they may need to share state between components, not just for display purposes, but also for managing, updating, or performing logic based on state values. Managing multiple states from multiple components efficiently becomes challenging as the application size increases.
Redux as a Solution: Redux is a state management library that addresses the challenge of handling multiple states in large applications. It stores and manages all application states centrally, providing APIs to make changes to the existing state and fetch the current state of the application.
In summary, Redux simplifies state management in applications by centralizing state storage and providing APIs for state manipulation, which becomes crucial as applications grow larger and more complex.
