Session Lost After Replit Restart
Users are logged out when your Replit app restarts or scales. Session data stored in memory is lost, forcing users to re-authenticate. This is critical for production apps.
Replit deployments can restart unexpectedly, and memory-based sessions don't persist across those events.
Common Causes
- Sessions stored in-memory instead of persistent storage
- No session database configured
- Redis session store not connected or credentials missing
- PostgreSQL sessions table not created
- Session timeout too short or not configured
How to Fix It
Switch from memory-based sessions to a database backend. Use Replit's PostgreSQL or connect to Redis. For Spring Boot, configure spring.session.store-type=jdbc or =redis with appropriate datasource properties. Ensure the sessions table exists and database credentials are in Replit Secrets.

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

What's the easiest way to persist sessions?
Use Replit's built-in PostgreSQL and configure Spring Session JDBC storage
Do I need Redis for sessions?
No, PostgreSQL works fine for most apps. Redis is better for high-traffic scenarios
