Posting to the SharePoint Newsfeed from an AngularJS application is simplified when you build your AngularJS ( application in a Visual Studio LightSwitch Cloud Business App project.

Posting to the SharePoint Newsfeed is simple when using a normal LightSwitch Cloud Business App. That process is described at this link. However, when using AngularJS, a call using the SharePoint client object model (CSOM) will provide the functionality required.

The Application


The AngularJS application runs as a SharePoint Provider Hosted Application inside a Visual Studio LightSwitch Cloud Business App project. It allows “To Do” items to be viewed and added.


When adding a new item, or selecting an exiting one (by clicking on it), a edit form appears.


After a item has been added, we can return to the main SharePoint site…


… select our “About me” page…


… and see that a post has been added to our Newsfeed.

Clicking on the link will take us directly to the application.

Creating The Application


We start with the SharePoint AngularJS application created in the article: An End-to-End AngularJS SharePoint Module using LightSwitch OData as a Back-End.


We open the project up and add Tenant permission.


We also add User Profiles (Social).


We open the ToDo entity in the editor…


… and select the _Inserting method.

We use the following code for the method:


        partial void ToDoes_Inserting(ToDo entity)
            //Load the properties for the SharePoint web object. 
            var clientContext = 
            Microsoft.SharePoint.Client.Web web = clientContext.Web;
            // Get the current web 
            // Get the AngularLightSwitchSP URL
            string AngularLightSwitchSP_url = "";
            // Get the WebCollection
            Microsoft.SharePoint.Client.WebCollection webs = web.Webs;
            // Loop thru each web to find AngularLightSwitchSP
            foreach (Microsoft.SharePoint.Client.Web objWeb in webs)
                if (objWeb.Title.ToLower() == "angularlightswitchsp")
                    // Get the URL
                    AngularLightSwitchSP_url = objWeb.Url;
            // Create a link to include in the post.
            SocialDataItem linkDataItem = new SocialDataItem();
            linkDataItem.ItemType = SocialDataItemType.Link;
            linkDataItem.Text = "link";
            linkDataItem.Uri = AngularLightSwitchSP_url;
            // Define properties for the post.
            SocialPostCreationData postCreationData = new SocialPostCreationData();
            postCreationData.ContentText = 
                entity.CreatedByInfo.FullName + " posted " + entity.TaskName + " {0}.";
            postCreationData.ContentItems = new SocialDataItem[1] { linkDataItem };
            // Get the SocialFeedManager instance.
            SocialFeedManager feedManager = new SocialFeedManager(clientContext);
            // Publish the post. This is a root post, so specify null for the
            // targetId parameter. 
            feedManager.CreatePost(null, postCreationData);


Note: You will need to add the following using statements to the class file:

using Microsoft.LightSwitch.Security.Server;
using Microsoft.SharePoint.Client.Social;

Note: You will need to add a reference to:


Located at  ..Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\
