shows data flow using models, controllers, views, and view controllers

example.js

// globals in /both/lib/namespaces.js
db = {};
PostsController = {};
Post = {};


// use iron router controllers with custom namespace
// in /both/controllers/posts.js
//
// render a page to create a new post
PostsController.new = AppController.extend({
  template: 'newPost'
});


// in /client/pages/posts/new.js
//
// template helpers are only responsible for passing data to the controller, they are faily dumb
Template.newPost.events(function(){
  'click .submit': function(e){
    e.preventDefault();
    var form = new ParseForm('#new-post-form');
    
    if (!formValid(form)) return;
    
    PostsController.create({
      title: form.title,
      description: form.desc
    });
  }
});


// add create controller method to update view on success/error
PostsController.create = function(data, callback) {
  log('[PostsController] create', data);

  // call Post model here...
  Post.create(data, function(err, id){
    if (callback) callback(err, id);
    if (err) return alert(err.reason);
    
    analytics.track('created post')
    Router.go('/somewhere');
  });
};


// in /both/models/posts.js 
// located in both folder to use on either server or client
// use allow/deny for security
//
Post.create = function(data, callback){
  log('[Posts] create', data);
  
  var newId = db.posts.insert(data, function(err, id){
    if (callback) callback(err, id);
    
    if (err) {
      trackError(err);
      return;
    }
  });
  
  return newId;
};
