Agenda• Introduction to SharePoint 2013 apps• Deployment options and design patterns• Technologies used in app development• Building a SharePoint-hosted app
setting the sceneIntroducing the new SharePoint app framework
Introducing appsIn SharePoint 2013 everything is an app …
In strict sense: “Apps are self-contained pieces of functionality that extend the capabilities of a SharePoint site.”
new deployment method
low server footprint
cloud driven
using app catalog
App isolation: App web vs Host web• Apps live in their own isolated environment called
the “app web”.• The site in which they function is called the “host
web”

Packaging and deployment optionsFarm
• Full access API• Server side
code• Server file level
access required• Classic model
from 2007• On-premise only
Sandbox Apps
• Partially trusted code service with limited server side code
• No file level access required
• Resource monitored
• Introduced with 2010
• Online deployment possible
• New model• Deploy from
corporate catalog or marketplace
• Limited server footprint
• Relies heavily on client-side technologies
• Online deployment possible

Visual Studio
Eclipse, PHP, etc....
DemoApps from end user perspective
Getting started with development• Local development• Has to be on Windows Server 2008 R2 (or later)• Memory reqs have gone up – 12 GB RAM seems
workable ... But TechNet recommends 24 GB• Extra configuration needed for app development• Visual Studio 2012
• Remote development• Sign up for Office 365 Developer Site• Possible to use NAPA – app for building apps
SharePoint App UX• Immersive App - app is shown full screen
with in a separate page • Part - App is shown as a part on the
SharePoint page – similar experience to web part
• UI Custom Actions – possible to make the App available through ribbon or menu actions for documents and items
See Apps for SharePoint UX design guidelines
DemoHello world SharePoint app
the bigger picturedeployment options, app identity and design patterns
Basic SharePoint App architecture• Code runs “Off SharePoint
Box”• Declarative Hooks into
SharePoint• AppWeb Host in SharePoint
Apps – three possible approaches
App Web
Parent Web
SharePoint-hosted AppProvision an isolated sub web on a parent web• Reuse web elements
(lists, files, out-of-box web parts)
• No server code allowed; use client JavaScript for logic, UX
Azure Auto-Provisioned AppWindows Azure + SQL Azure provisioned invisibly as apps are installed
Azure SharePoint Web
Get remote events from SharePoint Use CSOM/REST + OAuth to work with SPS
Cloud-based Apps
Developer-Hosted App“Bring your own server hosting infrastructure”Developers will need to isolate tenants
SharePoint
Web
Your Hosted
Site
Hosting: cloud vs SharePointCloud Hosted Apps SharePoint Hosted Apps
Possible hosting model for almost all types of apps
Good for smaller apps
Choose your own infrastructure & technology
SharePoint based; no server-side code
May require your own hosting Automatically hosted in SharePoint
May require your own handling of multitenancy & permission management
Inherent multitenancy & isolation
App identity• Challenge with SPS2010• Farm solutions – too much privileges - risk of
RunWithElevatedPrivileges• Sandbox solutions – no RunWithElevatedPrivileges –
always under user context• In SharePoint 2013 apps have their own identity
and specific permissions• Installing user either grants or denies permissions to host
web• Permission is explicitly given for a specific scope• App identity is passed around using oAuth tokens
App scopes• SPSite – site collection• SPWeb – site• SPList • Tenancy• Other scopes (and rights) for performing search
queries, accessing taxonomy data, user profiles, etc...
App rights• Default rights : Read, Write, Manage and Full Control• Not possible to customize• Apps are granted permissions to a scope and all
children of the scope• Defined in declarative XML
Azure Access Control Service (ACS)• ACS required with oAuth implementation in
SharePoint 2013• How is the ACS server configured as the
authentication server?• Automatically done for sites in Office 365 Preview• On-premise farms, a trust to ACS must be configured.
Possible to avoid when using Server-to-server (S2S) trust
DemoUsing App permissions
base technologiesSharePoint 2013 REST/CSOM API
SharePoint 2013 CSOM and REST API• Apps connect to SharePoint using
• SharePoint 2013 Client Side Object Model (CSOM)• SharePoint 2013 REST API• Javascript cross-domain library (SP.RequestExecutor.js)
• Main investments in 2013• Client.svc is extended with REST capabilities
• Easier for javascript and non .NET code• Implemented in accordance with oData protocol• Programming style is largely unchanged
• New APIs for SharePoint Server functionality• User Profiles, Search, Taxonomy, Feeds, ....
REST URLs in SharePoint 2013• CSOM URLs can go through _api folder• Replace
http://sharepoint/_vti_bin/client.svc/web• With
http://sharepoint/_api/web
• Example REST URLs targeting SharePoint sites• _api/web/lists• _api/web/lists/List1• _api/web/?$select=title,id• /_api/web/lists/getByTitle('Consultants')/Items• ....
ATOM XML vs JSON• Response data format selected with ACCEPT header• XML can be easier to deal with from managed code• JSON easier to deal with using Javascript• To get JSON response use “application/json”http://sharepoint/_vti_bin/client.svc/web
DemoExploring SPS 2013 REST API
building a SharePoint hosted appUsing Office 365 Developer site
SharePoint Hosted App• App components are SharePoint components• SharePoint list, site columns, content types• CSOM and REST API• Client web part
• Key Developer skills• HTML5, CSS, Javascript• Jquery, ASP.NET AJAX• CSOM and REST API• Silverlight
SharePoint Hosted App• Installation of App creates child site in target
site• App can add declarative items to App Web• App Web <-> Host Web communication:
CSOM/REST or Javascript cross-domain library • Full client-side extension – no server-side code
Host Web
App Web
• Custom Actions• Client-side web parts
• Lists• Site Pages• CSS files• Javascript files
