building document driven applications in node.js: couchbase connect 2014
DESCRIPTION
What’s different about this generation of web applications? The approach must consider the latency, throughput and interactivity demanded by users for social interaction across both mobile devices and browsers. We will show how Node.js’s programming model makes writing systems to provide this kind of interactivity easy and how Couchbase Server and the Node.js Couchbase SDK support this with a flexible data model. Come to this session ready to read code, since a sample game platform will be the basis of a demonstration of these techniques in action. We will show a sample game server, and key aspects of how the system is constructed for simplicity of data modeling, extensibility and scale.TRANSCRIPT
