Sails.js is a MVC web framework for Node.js built on Express. It is inspired by frameworks like Ruby on Rails and uses conventions over configurations. Sails.js features include a database-agnostic ORM, auto-generated REST APIs, and easy WebSocket integration. To get started, install Sails.js globally and use the sails command to generate a new project, lift the app, and generate models, controllers and REST APIs.

- 1. SAILS.JS AN INTRODUCTION | |Nic Jansma nicj.net @NicJ
- 2. SAILS.JS IS: A MVC backend web framework for Node.js Built on top of Express Inspired by Ruby on Rails / Symfony / Zend Convention over configuration Ideal for chat, realtime dashboards and multiplayer games
- 3. SAILS.JS CORE FEATURES 100% JavaScript Database agnostic (includes custom ORM) Auto-generated REST APIs Easy WebSocket support and integration with REST Reusable security policies Front-end agnostic Flexible asset pipeline (builds)

- 8. GENERATE MODEL AND REST API Let's create a new beermodel and REST API sailsgenerateapibeer This creates skeleton files: apicontrollersBeerController.jsand apimodelBeer.js
- 11. WHAT JUST HAPPENED Sails created a Model (Beer.js) and Controller (BeerController.js) Sails blueprints automatically configure new routes for the model (eg POST /beerand /beer/create). Sails uses whatever storage layer you want for persistence
- 12. ANATOMY OF A SAILS.JS APP api/controller/- controllers api/models/- models api/policies/- authentication / authorization api/responses/- res.xyz()handlers api/services/- services assets/- static assets config/- app config tasks/- grunt / cli tasks views/- views
- 13. MODELS api/models/* Uses (best parts of Active Record, Hibernate and Mongoose) http://sailsjs.org/#!documentation/models Waterline ORM module.exports={ attributes:{ name:{ type:'string', required:true }, brewery:{ type:'string', required:true }, have:{ type:'integer', defaultTo:1 } } };
- 14. CONTROLLERS api/controllers/* With Blueprints (config/blueprints.js), you automatically get CRUD REST and "shortcut" routes http://links.sailsjs.org/docs/controllers
- 15. BLUEPRINT ROUTES By default, Sails creates three types of blueprint routes: RESTful routes for /:model(HTTP GET, DELETE, etc) Shortcut routes to easily test your model via HTTP GET requests, such as /:model/delete/:id(should be turned off in production) Action routes for any additional actions in your controllers Authentication and access control are handled via policies
- 16. BLUEPRINT ROUTES REST Shortcut Query GET /api/:model Fetch GET /api/:model/:id Create POST /api/:model GET /api/:model/create Update PUT /api/:model/:id GET /api/:model/update/:id Delete DELETE /api/:model/:id GET /api/:model/destroy/:id
- 17. BLUEPRINT ACTIONS By default, Sails creates actions on your controllers for ORM functionality: find findOne create update destroy populate add remove
- 19. VIEWS api/views/* Uses EJS by default but can switch to Jade, etc http://sailsjs.org/#!documentation/views //BeerController.js module.exports={ show:function(req,res){ Beer.find({},function(err,beers){ res.view('show-beers',{title:'Beers',beers:beers}); }); } }; //show-beers.ejs <ul> <li> </li> </ul> <%for(vari=0;i<beers.length;i++){%> <%=beers[i].name%> <%}%>
- 20. SOCKET.IO INTEGRATION Sails automatically translates incoming socket.io messages into Express requests Also gives you Pub/Sub via res.broadcast()and req.join() varsocket=io.connect('http://localhost:1337'); socket.request('/beer',{},function(beers){console.log(neers);});
