A simple cookie-based session middleware for Express and Connect that stores session data on the client within a signed cookie, requiring no server-side storage. It attaches a session object to the request and automatically sets cookies when session contents change.

Use cases

• add cookie-based sessions to an express app
• store light session data without a database
• simplify sessions in load-balanced deployments
• reduce database lookups for session state
• manage user sessions in nodejs middleware

When to choose

• session data is small enough to fit in a cookie
• you want to avoid server-side session storage or a database
• you run load-balanced servers and want stateless sessions
• you need a lightweight express/connect middleware

When to avoid

• you need to store secret or sensitive data in the session (contents are not encrypted)
• session replay protection is required
• session data exceeds browser cookie size limits
• you need server-side session storage or revocation
