{"version":"1.0","type":"rich","title":"Express authentication using Redis for session store and Couchdb for database (in coffeescript!)","description":"This example shows a complete Express authentication system that uses Redis as a session store and CouchDB as the user database, with CoffeeScript as the implementation language. The code demonstrates session management with `req.session.regenerate()` and `req.session.destroy()`, password hashing via `hash.sha1`, and CSRF protection through the `csrf.check()` middleware. Routes for login, signup, dashboard, and logout interact with the CouchDB client through `db.getDoc` and `db.saveDoc`, while the fugue library handles multi-process server startup.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-1360068?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
