Cookie Session Middleware

cookie-session is a lightweight middleware for Node.js, primarily used with Express, that implements client-side session management. Unlike server-side session stores (like `express-session`), this module stores the entire session data directly within a signed, but unencrypted, cookie on the client's browser. This approach means no server-side database or resources are required for session storage, which can simplify deployments, especially in load-balanced environments. The current stable version is 2.1.1, released in April 2024, indicating active maintenance. Releases typically align with updates to its underlying `cookies` and `keygrip` dependencies, or to address compatibility with newer Node.js versions. Key differentiators include its minimal server-side footprint and the direct storage of session data in the client's cookie, making it suitable for 'light' sessions or as a complement to a secondary, database-backed store for larger data payloads.
