This presentation was given at the Mar 11, 2014 AngularJS meetup talk at Google. The talk covered the DreamFactory open source REST API platform, Angular's built-in services for making API calls, and a new open source Angular module called angular-dreamfactory for consuming REST APIs for SQL, NoSQL, BLOB storage, and remote web services.

We Make Enterprise Apps
Less Code
Flexible Deployment
Mobile Architecture
Existing Data
User Management
Our Wish List…
We Wanted
Less Code REST APIs Provided
Flexible Deployment
Open Source, Install Anywhere
Mobile Architecture
REST & JSON
Existing DataSQL, NoSQL, BLOB, Remote
User Management
Roles, Auth, Access Control
It Didn’t Exist
State of the Art…
1) Build REST APIs By Hand 2) Build Security By Hand3) Build User Management By Hand
Repeat for every new project

$scope
• Keep Data for Lifetime of App (Singleton)
• Created as Needed (Lazy Loaded)• Share Data Across Controllers• Built-In Services / Write Your Own
Server Calls with Angular
$http – wraps XMLHttpRequest object$resource – supports RESTful data model
Restangular – service to handle RESTful resources easily
angular-dreamfactory
Open source Angular module Dynamically generated when app loadsIntegrates your app with DSP REST services
Built on $http service (no $scope.apply required) Add a REST service to DSP and instantly available
