SharePoint Server 2013: to app or not to app?

  1. 1. SharePoint 2013:To App or not toApp?
  2. 2. About me
  3. 3. Agenda• Introduction to SharePoint 2013 apps• Deployment options and design patterns• Technologies used in app development• Building a SharePoint-hosted app
  4. 4. setting the sceneIntroducing the new SharePoint appframework
  5. 5. Introducing appsIn SharePoint 2013 everything is an app …In strict sense: “Apps are self-contained pieces of functionalitythat extend the capabilities of a SharePoint site.”
  6. 6. 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” APP1UID GUIDAPP1
  7. 7. Packaging and deployment options
  8. 8. SharePoint 2013 app developmentscenarios
  9. 9. Demo
  10. 10. 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
  11. 11. 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
  12. 12. Demo
  13. 13. Basic SharePoint App architecture• Code runs “Off SharePoint Box”• Declarative Hooks into SharePoint• AppWeb Host in SharePoint
  14. 14. Apps – three possible approaches Developer-Hosted AppCloud-based “Bring your own server hosting SharePoint Your HostedApps infrastructure” Web Site Developers will need to isolateGet remote tenantsevents fromSharePoint Azure Auto-Use CSOM/REST Provisioned App SharePoint Azure+ Windows Azure + SQL AzureOAuth to work provisioned invisibly as apps Webwith SPS are installed SharePoint-hosted App Parent Provision an isolated sub web on a parent web Web • Reuse web elements App Web (lists, files, out-of-box web parts) • No server code allowed; use client JavaScript for logic, UX
  15. 15. Hosting: cloud vs SharePointCloud Hosted Apps SharePoint Hosted AppsPossible hosting model for almost all types Good for smaller appsof appsChoose your own infrastructure & SharePoint based; no server-side codetechnologyMay require your own hosting Automatically hosted in SharePointMay require your own handling of Inherent multitenancy & isolationmultitenancy & permission management
  16. 16. 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
  17. 17. App scopes• SPSite – site collection• SPWeb – site• SPList• Tenancy• Other scopes (and rights) for performing search queries, accessing taxonomy data, user profiles, etc...
  18. 18. 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
  19. 19. 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
  20. 20. Demo
  21. 21. 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, ....
  22. 22. 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 • ....
  23. 23. 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
  24. 24. DemoExploring SPS 2013 REST API
  25. 25. 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
  26. 26. 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 • Custom Actions • Client-side web parts • Lists • Site Pages • CSS files • Javascript files
