Selected choice: Use the current folder
Deployment option: Selecting Y will allow the app to be deployed instantly to all sites and will be accessible everywhere.
Selected choice: Y

In a class, define a variable to store Microsoft Teams context.

Add the onInit() method to set the Microsoft Teams context.
  1. protected onInit(): Promise<any> {  
  2.   let retVal: Promise<any> = Promise.resolve();  
  3.   if (this.context.microsoftTeams) {  
  4.     retVal = new Promise((resolve, reject) => {  
  5.       this.context.microsoftTeams.getContext(context => {  
  6.         this._teamsContext = context;  
  7.         resolve();  
  8.       });  
  9.     });

  3.   let siteTabTitle: string = '';  
  5.   if (this._teamsContext) {  
  6.     // We have teams context for the web part  
  7.     title = "Welcome to Teams!";  
  8.     siteTabTitle = "Team: " + this._teamsContext.teamName;  
  9.   }  
  10.   else  
  11.   {  
  12.     // We are rendered in normal SharePoint context  
  13.     title = "Welcome to SharePoint!";  
  14.     siteTabTitle = "SharePoint site: " + this.context.pageContext.web.title;  
  15.   }  
  17.   this.domElement.innerHTML = `  
  18.     <div class="${ styles.teamsTab }">  
  19.       <div class="${ styles.container }">  
  20.         <div class="${ styles.row }">  
  21.           <div class="${ styles.column }">  
  22.             <span class="${ styles.title }">${title}</span>  
  23.             <p class="${ styles.description }">${siteTabTitle}</p>  
  24.             <p class="${ styles.description }">Description property value - ${escape(}</p>  
  25.             <a href="" class="${ styles.button }">

  27.             </a>  
  28.           </div>  
  29.         </div>  
  30.       </div>  
  31.     </div>`;  
  32. }  

Package and Deploy web part to SharePoint

On the command prompt, run the below command to bundle the solution.
  1. gulp bundle --ship  
Run the below command to package the solution.
  1. gulp package-solution --ship  
This will create spfx-teams-tab.sppkg package under the SharePoint/solution folder.
Open SharePoint App catalog site.
Upload spfx-teams-tab.sppkg to the app catalog.
Check “Make this solution available to all sites in the organization” option.
Click Deploy.

Test the WebPart in SharePoint 

  1. Open SharePoint site
  2. Add the web part to the page.
  3. The web part shows the SharePoint site context information.

Make web part available in Microsoft Teams

To make the web part available in Microsoft Teams, we will have to synchronize the solution with teams.
  1. Select the solution in the app catalog.
  2. From the ribbon, click Files.
  3. Select Sync to Teams.

Test web part in Microsoft Teams

  • Open Microsoft Teams.
  • Under existing team, select channel (by default, General channel is available under team).
  • Click + to add a new tab.
  • Select your custom tab from the list.
  • Click Install.
  • Click Save.
  • Our web part will appear as a custom tab in Microsoft Teams.


SharePoint Framework version 1.8 eases the development of Microsoft Teams tabs using SharePoint Framework. The same web part solution can work on both SharePoint and Microsoft Teams based on the context under which it is running.
