Centralizing User Session Persistence in ProyectoFinal_G14

Managing user state across a distributed application is a common challenge, especially when trying to maintain a consistent session identity throughout the user journey. In the ProyectoFinal_G14 project, we recently focused on streamlining how session data is handled to ensure that user information remains available and accurate.

The Challenge

When building out authentication and user-specific features, we found that passing session state manually through various components was becoming brittle. We needed a centralized way to handle session data that would decouple the business logic from the underlying storage mechanism.

The Implementation

To address this, we implemented a dedicated session management layer. By abstracting the session data access, we ensure that individual modules do not need to know where the data is coming from or how it is persisted.

In our Java-based backend, we introduced a structured approach to encapsulate session details:

public class SessionManager {
    private UserSession currentSession;

    public void saveSession(UserSession session) {
        this.currentSession = session;
        // Logic to persist session to store
    }

    public UserSession getActiveSession() {
        return this.currentSession;
    }
}

This SessionManager acts as the single source of truth. When a user logs in, their profile data is instantiated into a UserSession object and held by the manager, allowing other services to query the state without re-fetching or re-parsing authentication tokens.

Why It Matters

By centralizing this logic, we achieved two key goals:

1. Consistency: All parts of the application now interact with the session through a defined API rather than direct field access.
2. Maintainability: If the underlying storage for session data changes in the future, we only need to update the SessionManager class rather than hunting through the entire codebase.

This shift simplifies the interaction between our controllers and our data services, making the project more robust as we continue to scale our feature set.
