How do stateful applications work?

Date:2023-01-07
Stateful applications work by maintaining a specific server-side or client-side state that stores information or data used by the application. This information or data is kept as part of the application's internal state and changes as the user interacts with it. It may be stored in a database, an in-memory data structure, or in the application's context. The application keeps track of the user's current state, allowing for it to make decisions and update the user's experience based on those decisions. For example, a web application may track the user's current page and the items the user has added to their shopping cart. By understanding the user's current state, the web application can personalize the user's experience and make recommendations based on items the user may have previously expressed interest in.
