How good is it practice to store user profile and cart information in the global Redux store simultaneously? How does it affect architecture?

Storing user profile information and the cart simultaneously in a global Redux store is a common practice, but it requires a well-thought-out architecture.

Pros:

• Centralized state management simplifies access to data from different components.
• Provides a single source of truth.

Cons and risks:

• If the store becomes too large and contains many different data, it can lead to difficulties in maintenance and scaling.
• Frequent updates to the cart can cause re-rendering of components subscribed to the profile, and vice versa, which reduces performance.

Recommendations:

• Divide the store into logical slices, such as userProfile and cart, using Redux Toolkit.
• Use selectors and memoization (reselect) to minimize unnecessary component updates.
• If necessary, consider local state for less critical data to avoid cluttering the global store.

Thus, storing the profile and cart in a single global store is a normal practice if the architecture is organized with responsibility separation and performance optimization in mind.
