1 CompoundJS Node on rails

2 Turinys Node pristatymas Node platformos Sintaksės palyginimas Našumo palyginimas

3 Node? Kas tai? 1 http = require("http") 2 onrequest = (request, response)-> 3 console.log("request received.") 4 response.writehead(200, {"Content-Type": "text/plain"}) 5 response.write("hello World") 6 response.end() 7 http.createserver(onrequest).listen(8888) 8 console.log("server has started.")

4 Node? Kodėl?

5 Augantis populiarumas Google paieškos: "ruby on rails" VS "node.js" Darbo skelbimai: "ruby on rails" VS "node.js"

6 O dar kodėl? Nereikia mokytis dar vienos kalbos Auganti bendruomenė Platus platformų, plėtinių pasirinkimas Platesnės kodo perpanaudojamumo galimybės Nesiblokuojantys procesai

7 Platformos Sails CompoundJs Geddy TowerJs

8 Sails Naujas Pasirenkama DB Rails tipo generatoriai Shared templates MVC architektūra Orientuotas į backend (JSON by default) Lengvai valdomas per Socket.io

9 Geddy Rails tipo generatoriai MVC architektūra Templates: EJS, jade, handlebars CSS framework: - Duomenų bazė: laisvai pasirenkama

10 TowerJs Rails tipo generatoriai MVC architektūra DB: database-agnostic BackgroundJobs: Redis Tests: Jasmine (arba vows, qunit, assert) CSS: stylus (arba less, css) CoffeeScript FTW! visas kodas coffescript by default (arba: js) coffeecup template'ai by default (arba: jasmine, mustache)

11 CompoundJs Rails tipo generatoriai MVC architektūra DB: Mongo, Redis, Mysql... Tests: nodeunit CSS: stylus (arba less, sass, css) Galimybė viską rašyt coffeescriptu Template: erb, jade (+ twitter bootstrap) Shared kodas tarp browserio ir serverio
