AngularJS is an MVC framework for building dynamic browser-based applications, using two-way data binding between models and views, and dependency injection to separate concerns; it includes routing, directives to extend HTML, services for reusable logic, and animation capabilities to build robust and testable single-page web apps.

- 3. What is AngularJS? Getting started Objectives Directives Routing Dependency injection REST data services Animations
- 4. AngularJS is an MVC framework for browser based apps Open source and originally developed at Google The clean architecture has attracted a large following quickly What is AngularJS? Version 1.0 was released in June 2012 Currently at 1.0.8/1.2.0-rc-3 The goal is building CRUD style business applications Not as suitable for games etc Use declarative programming for UI and imperative programming for the logic The application is wired together in a declarative way Supports modern desktop and mobile browsers Internet Explorer version 8 and above
- 5. Model View Controller architecture A well known and proven architecture Declarative two way data binding Automatically synchronizes values between Model and View Dynamic templates Key features Makes it very easy to update the user interface Dependency injections Code dependencies are automatically injected where needed Extends HTML with directives Lots of powerful standard directives or create your own Build with testing in mind Makes it much easier to unit test different parts
- 6. Automatic bootstrapping Bootstrapping Add a reference to AngularJS Add the ngApp attribute Manual bootstrapping is also possible Gives you more control For example when using AMD/RequireJS
- 8. Model Model The business data Exposed to the view through the $scope Controller View
- 9. Model The user interface layer View Controller Data binds to the model Calls functions on the controller Use declarative directives for reusable code View
- 10. Directives allow you to enhance HTML with new capabilities Start using HTML as a domain specific language AngularJS comes with a long list of standard directives Standard directives ngApp ngBind ngModel ngRepeat ngClick ngEnable/ngDisable ngHide/ngShow ngView …
- 11. Model Controller Controller Glues the view and the model together Provides additional functionality Uses additional services for reusable logic View
- 12. Used to create SPA style application The page can change without using the server The ngView is often used to render a template HTML templates loaded when needed Can also be pre loaded as script with type="text/ng-template" Routing The $routeProvider service is used to configure the route The $location service can be used to navigate Using an anchor tag is also possible The $routeParams service can be used to retrieve parameters Properties named in the route URL template Requires a dependency on ngRoute in AngularJS 1.2 Located in angular-route.js
- 13. AngularJS uses dependency injection to decouple modules Dependency injection Dependencies are automatically injected by the framework Based on the parameter name JavaScript is often minified in production Need to provide AngularJS with some extra hints
- 14. Model Services View Services are reusable pieces of business logic Services Separation results in reuse and testability Controller Created as singleton objects Inject by AngularJS using dependency injection Services are created as part of a module One module can take a dependency on another module Modules are groupings of related functionality Also used to bootstrap the application
- 15. Many general purpose services provided by AngularJS $http Used for XMLHttpRequest handling $location Standard Services Provide information about the current URL $q A promise/deferred module for asynchronous requests $routeProvider Configure routes in an SPA $log Logging service Many more
- 16. The basic service for doing all HTTP requests The building block for all AJAX requests Can be used as a function $http(config) $http service Provides a number of shortcut methods $http.post(url, config) $http.get(url, config) $http.put(url, config) $http.delete(url, config) Uses the promises API as the result Provided by the $q service
- 17. Creates a service for working with RESTful services Much easier than using the $http object $resource Standard functions are already preconfigured Only the common HTTP PUT is missing Requires a dependency on ngResource Located in angular-resource.js
- 18. AngularJS is a complete framework for client side applications Based on the standard MVC design pattern Summary Two way data binding makes it easy to build data entry forms Dependency injection makes it easy to separate modules Build with testing in mind
