Agenda
• SharePoint 2013 App Primer
• JavaScript “Function” Primer
• Asynchronous Patterns in JavaScript
Terminology
Host Web – A SharePoint website where the app is installed and surfaced to the user.
App Web – An isolated SharePoint web site on the SharePoint app domain that hosts SharePoint components used in the app
Hosting Architectures
SharePoint Hosted – App is hosted by SharePoint
Provider Hosted – App is hosted on a dedicated server either on-premises or on a third party hosting service
SharePoint-hosted Apps
Runs on an isolated app domain of the SharePoint farm
Authorized using the privileges of the signed in user
Can only use JavaScript and HTML- No server side code
Provider-hosted Apps
Runs on a dedicated server or hosting service (not in SharePoint)
Authorization is through OAuth or the JavaScript cross-domain library
Can use any language supported by the web server or hosting service
JavaScript Functions
Functions are Objects in JavaScript. Essentially they are strings of JavaScript code.
Callbacks
A callback is a function that is passed to another function as a parameter and somehow affects the flow of execution
Functions are Objects in JavaScript
Promises
A promise represents the eventual value returned from the single completion of an operation.
Three states
• Unfullfilled
• Fulfilled
• Rejected
Promises
In jQuery the Promise pattern can be used with $.when(object) where object is a deferred object or a promise
