DevMeetings are free workshops for advanced software developers. We come here to present to you Java guys the serverside usage of JavaScript. Many say JS is not a serious enviroment, but we’ll show a real-life case of how can you implement a complete backend functionality within hours.

node.js + websockets workshop

Node.js is a great tool for building extremely fast and scalable web servers. It is based on the V8 JavaScript engine. You can simply advertise Node.js with: "complete server in a few lines of code" and it will not be only a marketing lie. The workshop will present you the details of construction and operating principles in Node.js in a case study: live coding backend implementation for web fighting game. The very essence of Server-side JavaScript coding. We will look at issues of concurrency in endless event loop with non-blocking I/O, module system in Node.js called CommonJS, high performance Sinatra style REST library named ExpressJS. We will also discuss about a cross-browser WebSocket for realtime apps and how to easy implement persistent layer with modules for MySQL or MongoDB. In conclusion we will present current trends and future of Node.js.
