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
<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

Configure web part

  • in the command line
    • change the working directory to the webpart folder
    • run npm i
  • in your code editor open the webpart folder
  • in the ./src/webparts/createTask/components/CreateTask.tsx file
    • in line 76 replace the URL with the URL of your API App
  • in the command line execute gulp serve
  • add the web part to SharePoint workbench
  • enter the name of the new item and click the Create button
    • 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

You can’t perform that action at this time.
