Astro Cookie Session

Middleware for managing session data using cookies in Astro SSR applications. Current version 1.3.0 (released 2024-12, active development). Session data is encrypted and stored client-side in cookies, not on the server, making it suitable for stateless architectures. Supports TypeScript with type-safe session definitions and optional flash messages. Key differentiators: zero external dependencies beyond Astro, encryption of payloads (added in 1.3.0), simple API similar to remix-run session handling, and built-in flash message support.
