  Firebase Primer • Whatis Firebase? – An API to store and sync data in real-time – Easy to setup real-time persistence – Configurable security and access control rules – User authentication using Facebook, Twitter, Github, Google and custom tokens

  Firebase Architectural considerations: • Canbe used in conjunction with Cloud providers(Azure, AWS, GAE, etc) • Build a simple 2-tier architecture • Client/Server share firebase • Firebase handles real-time data, server handles the rest

  Angular JS • Two-waydata binding • Dependency injection • Event architecture • Reusable components • End-to-end integration testing/Unit testing • Routing & Templating What is Angular.js? Client side JavaScript framework for building web applications Key concepts Directive, Views, Modules, Controllers, $scope, Services
• 12.
  Directives What are directives? Ata high level, directives are markers on a DOM element (such as an attribute, element name, comment or CSS class) that tell AngularJS's HTML compiler ($compile) to attach a specified behavior to that DOM element or even transform the DOM element and its children. Types of directives: <my-dir></my-dir> <span my-dir="exp"></span> <!-- directive: my-dir exp --> <span class="my-dir: exp;"></span> Relevant directives: • Ng-app • Ng-model • Ng-controller • Ng-click
• 13.
  Modules What are modules? Youcan think of a module as a container for the different parts of your app – controllers, services, filters, directives, etc. Why use modules? • declaratively specify how an application should be bootstrapped • package code as reusable modules • modules can be loaded in any order (or even in parallel) because modules delay execution Relevant modules: • Firebase
• 14.
  $scope What is $scope? •an object that ties a view (a DOM element) to the controller. • $scope object becomes the model. It provides an execution context that is bound to the DOM element Although it sounds complex, the $scope is just a JavaScript object. Both the controller and the view have access to the $scope so it can be used for communication between the two. This $scope object will house both the data and the functions that we’ll want to run in the view, as we’ll see. References: https://github.com/angular/angular.js/wiki/Understanding-Scopes

  Controllers What are controllers? InAngular, a Controller is a JavaScript constructor function that is used to augment the AngularScope. When a Controller is attached to the DOM via the ng-controller directive, Angular will instantiate a new Controller object, using the specified Controller's constructor function. A new child scope will be available as an injectable parameter to the Controller's constructor function as $scope. Purpose of controllers: • Set up the initial state of the $scope object • Add behavior to the $scope object Relevant controllers: • DemoCtrl
• 16.
  Services What are services? Angularservices are substitutable objects that are wired together using dependency injection (DI). You can use services to organize and share code across your app. Angular services are: • Lazily instantiated – Angular only instantiates a service when an application component depends on it. • Singletons – Each component dependent on a service gets a reference to the single instance generated by the service factory. Angular offers several useful services (like $http), but for most applications you'll also want to create your own. Relevant services: • $firebase

  Using Angular JSwith Firebase • Commoditized backend(data store with real- time syncing, authentication, security rules for data access control, geofire etc) with hosting • 3-way data binding enabling real-time data syncing • Allows for quick prototyping of applications

  Demo! • Demo asimple to-do list using angular and firebase(CodePen) – Create a new firebase app using the account – Use codepen to write/test the code for the app – Deploy the code on firebase hosting – Discuss authentication, data storage & data access security rules features of firebase – Discuss architectural considerations using firebase • Demo of InCloudTrn app
