I’m exploring different approaches to managing state in Trongate v2 applications and would love to hear how others handle this.

Trongate’s default architecture is stateless—each request loads modules fresh, which is great for simplicity and scalability. But real‑world applications often need to persist some state across requests: user authentication, shopping carts, multi‑step forms, temporary preferences, etc.

What patterns have you found most effective in Trongate v2?

**Options I’ve considered:**

1. **PHP native sessions** – Easy to set up, but they come with file‑locking concerns and can be tricky to scale horizontally.
2. **Database‑backed sessions** – Storing session data in a `sessions` table gives more control and scalability, but adds DB overhead.
3. **JWT / token‑based auth** – Useful for API‑driven apps, but requires careful handling of token storage and refresh.
4. **Cookies for small, non‑sensitive data** – Simple, but limited in size and security.
5. **Custom state service** – A dedicated module that uses the database (or a key‑value store) to manage state with explicit expiration and cleanup.

**Specific questions:**

- Do you use Trongate’s built‑in session helpers, or do you roll your own?
- How do you handle state in SPAs or heavily interactive front‑ends that talk to Trongate via AJAX?
- Any pitfalls you’ve encountered with session concurrency or race conditions?
- For larger applications, have you integrated external stores like Redis, and if so, how did you wire it into Trongate’s module system?

I’m especially interested in patterns that keep the code clean, testable, and aligned with Trongate’s philosophy of simplicity.

Thanks in advance for your insights!
