State management is a critical concept in software development, especially in web applications. It refers to how applications track and manage data across user interactions. Here's a quick overview:
Key Concepts 📚
Stateful vs. Stateless:
Stateful systems retain data between requests (e.g., session storage), while stateless systems rely on client-side data (e.g., JWT tokens).Use Cases:
- Managing user authentication status
- Tracking form input across multiple pages
- Handling real-time updates in single-page applications (SPAs)
Best Practices 🛡️
- Use server-side session storage for sensitive state data
- Implement caching strategies for performance optimization
- Follow the Principle of Least Astonishment when designing state transitions
