About a month ago I had written about creating a user profile store and session store using Node.js and Couchbase. This is a valuable concept for every major organization as it demonstrates how to store your user data with NoSQL.
To compliment that article, I thought it would be great to have a start-to-finish video tutorial on the subject.
The above video is quite lengthy, but it is a complete guide towards creating and managing user profiles as well as auto expiring sessions managed by the database.
For more information on using Couchbase Server or the Node.js SDK, check out the Couchbase Developer Portal.
