Minimal Path to Awesome

• clone this repo

Deploy custom Web API

• in the Azure Management Portal at https://portal.azure.com create a new API App
  • in the settings enable CORS for all origins using an *
  • copy the URL of the API App
• in your SharePoint site
  • create a new list called Tasks
  • navigate to https://yourtenant.sharepoint.com/_layouts/15/appregnew.aspx
    • generate client ID and copy it
    • generate client secret and copy it
    • as the name use: SPFx sample elevated privileges
    • as the URL use the URL of the Azure API App created previously
    • as the domain use the host name of the Azure API App
  • navigate to https://yourtenant.sharepoint.com/_layouts/15/appinv.aspx
    • lookup the newly registered Add-in using the client ID you copied
    • in the Permissions field past the following code:

<AppPermissionRequests AllowAppOnlyPolicy="true">
  <AppPermissionRequest Scope="http://sharepoint/content/sitecollection/web/list" Right="Write" />
</AppPermissionRequests>

• after confirming the changes, when prompted, select the previously created Tasks list
• from the api folder, in Visual Studio open the pnp.api.elevatedprivileges.sln file
• in the web.config file
  • update the value of the clientId setting with the previously copied client ID
  • update the value of the clientSecret setting with the previously copied client secret
  • update hte value of the siteUrl setting with the URL of your SharePoint site
  • if you named your list other than Tasks update the value of the listName property with the name of your list
• build the solution
• deploy the pnp.api.elevatedprivileges project to the newly created API App
• verify that you can access the API by navigating in your web browser to https://your-api-app.azurewebsites.net/api/items
  • you should get an error that GET is not a supported method

  • verify that a new item with the name you specified has been created in the Tasks list

Features

This project contains sample Web API using app-only permissions to create items in a specific SharePoint list, and a client-side web part connected to that API.

This project illustrates the following concepts:

• elevating user privileges for communicating with SharePoint through a custom Web API
• connecting SharePoint Framework client-side web part to a custom Web API hosted in Azure
• persisting state in React components
• communicating state updates in React components to users
• executing REST API web requests from React components
• using Office UI Fabric React components in SharePoint Framework client-side web parts
• using form controls in Rest components
