What data is better to store in Store and what to keep in services?

In frontend development, Store is usually used to store the application state — data that affects the UI and can change during the user's interaction.

What is better to store in Store:

• Data necessary for displaying the interface (e.g., product list, filter states, current user).
• State that should be accessible from different components.
• Data that needs to be preserved between page transitions.

What is better to store in services:

• Logic for interacting with APIs (requests, response handling).
• Auxiliary functions and business logic.
• Temporary data that does not directly affect the UI and does not require reactive updates.

Thus, Store is for reactive state and data affecting the UI, while services are for working with external sources and business logic.
