Transcript

1. Realtime apps/games Paweł Smoczyk Using Node.js with Rails
2. Based on GeoRun realtime platform
3. Agenda • What we needed? • Our chosen stack (frameworks) • How it works • Why we did it this way? • Demo • Other simpler solutions
4. What we needed? • Gameplay backend for realtime communication (sockets) • Admin interface for prizes management, reports, users etc. • Gameplay editor • Gameplay player (for browsers) • Mobile clients (not relevant)
5. Our chosen stack Admin interface Gameplay editor + player + Realtime communication
6. How it works Node.js Redis Node.js Rails Resque
7. Why we did it this way? • Rails is GREAT! (crud, gems, reports, stats) • Writing everything in Node.js would be an asynchronous hell... • Node.js has great integration with Socket.IO • Almost no code reuse in EventMachine (asynchronous vs synchronous) • Node.js seems to be more reliable when it comes to sockets • Asynchronous code is cleaner in Node.js (with CoffeeScript)
8. DEMO
9. Other solutions • Faye (+ private pub) • Juggernaut • Slanger (self hosted Pusher) • 3rd party services (Pusher, PubNub and more...) • Meteor, Derby ???
