Personal Tabs

Tabs are Teams-aware webpages embedded in Microsoft Teams. A channel/group tab delivers content to channels and group chats, and are a great way to create collaborative spaces around dedicated web-based content.

Included Features

• Tabs

Interaction with app

Prerequisites

• NodeJS

• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

• dev tunnel or Ngrok (For local environment testing) latest version (any other tunneling software can also be used)

• Teams Microsoft Teams is installed and you have an account

• Teams Toolkit for VS Code or TeamsFx CLI

Run the app (Using Teams Toolkit for Visual Studio Code)

The simplest way to run this sample in Teams is to use Teams Toolkit for Visual Studio Code.

1. Ensure you have downloaded and installed Visual Studio Code
2. Install the Teams Toolkit extension
3. Select File > Open Folder in VS Code and choose this samples directory from the repo
4. Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
5. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
6. In the browser that launches, select the Add button to install the app to Teams.

If you do not have permission to upload custom apps (sideloading), Teams Toolkit will recommend creating and using a Microsoft 365 Developer Program account - a free program to get your own dev environment sandbox that includes Teams.

Setup

1. Register a new application in the Microsoft Entra ID – App Registrations portal.
   • Select New Registration and on the register an application page, set following values:
   • Set name to your app name.
   • Choose the supported account types (any account type will work)
   • Leave Redirect URI empty.
   • Choose Register.
   • On the overview page, copy and save the Application (client) ID, Directory (tenant) ID. You’ll need those later when updating your Teams application manifest and in the appsettings.json.

• Under Manage, select Expose an API.

• Select the Set link to generate the Application ID URI in the form of api://{AppID}. Insert your fully qualified domain name (with a forward slash "/" appended to the end) between the double forward slashes and the GUID. The entire ID should have the form of: api://fully-qualified-domain-name/{AppID}

  • ex: api://%ngrokDomain%.ngrok-free.app/00000000-0000-0000-0000-000000000000.

• Select the Add a scope button. In the panel that opens, enter access_as_user as the Scope name.

• Set Who can consent? to Admins and users

• Fill in the fields for configuring the admin and user consent prompts with values that are appropriate for the access_as_user scope:

  • Admin consent title: Teams can access the user’s profile.
  • Admin consent description: Allows Teams to call the app’s web APIs as the current user.
  • User consent title: Teams can access the user profile and make requests on the user's behalf.
  • User consent description: Enable Teams to call this app’s APIs with the same rights as the user.

• Ensure that State is set to Enabled

• Select Add scope

  • The domain part of the Scope name displayed just below the text field should automatically match the Application ID URI set in the previous step, with /access_as_user appended to the end:
    • `api://[ngrokDomain].ngrok-free.app/00000000-0000-0000-0000-000000000000/access_as_user.

• In the Authorized client applications section, identify the applications that you want to authorize for your app’s web application. Each of the following IDs needs to be entered:

  • 1fec8e78-bce4-4aaf-ab1b-5451cc387264 (Teams mobile/desktop application)
  • 5e3ce6c0-2b1f-4285-8d4b-75ee78787346 (Teams web application) Note If you want to test or extend your Teams apps across Office and Outlook, kindly add below client application identifiers while doing Azure AD app registration in your tenant:
  • 4765445b-32c6-49b0-83e6-1d93765276ca (Office web)
  • 0ec893e0-5785-4de6-99da-4ed124e5296c (Office desktop)
  • bc59ab01-8403-45c6-8796-ac3ef710b3e3 (Outlook web)
  • d3590ed6-52b3-4102-aeff-aad2292ab01c (Outlook desktop)

• Navigate to API Permissions, and make sure to add the follow permissions:

• Select Add a permission

•  Select Microsoft Graph -> Delegated permissions.

  • User.Read (enabled by default)

• Click on Add permissions. Please make sure to grant the admin consent for the required permissions.

• Navigate to Authentication If an app hasn't been granted IT admin consent, users will have to provide consent the first time they use an app. Set a redirect URI:

  • Select Add a platform.
  • Select web.
  • Enter the redirect URI for the app in the following format: https://%ngrokDomain%.ngrok-free.app/Auth/End. This will be the page where a successful implicit grant flow will redirect the user.

  Enable implicit grant by checking the following boxes:
  ✔ ID Token
  ✔ Access Token

• Navigate to the Certificates & secrets. In the Client secrets section, click on "+ New client secret". Add a description (Name of the secret) for the secret and select “Never” for Expires. Click "Add". Once the client secret is created, copy its value, it need to be placed in the appsettings.json.

2. Setup NGROK

• Run ngrok - point to port 3978

  ngrok http 3978 --host-header="localhost:3978"

  Alternatively, you can also use the dev tunnels. Please follow Create and host a dev tunnel and host the tunnel with anonymous user access command as shown below:

  devtunnel host -p 3978 --allow-anonymous

3. Setup for code

• Clone the repository

  git clone https://github.com/OfficeDev/Microsoft-Teams-Samples.git

• In a terminal, navigate to samples/tab-personal-quickstart/ts

• Install modules

  npm install

• Run your app

  npm start

4. Setup Manifest for Teams

• This step is specific to Teams. Edit the manifest.json contained in the appManifest/ folder to replace with your MicrosoftAppId (that was created in step1.1 and is the same value of MicrosoftAppId in .env file) everywhere you see the place holder string {{Microsoft-App-Id}} (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json) Edit the manifest.json for validDomains and replace {{domain-name}} with base Url of your domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app then your domain-name will be 1234.ngrok-free.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms. Note: If you want to test your app across multi hub like: Outlook/Office.com, please update the manifest.json in the tab-personal-quickstart\ts\appManifest_Hub folder with the required values. Zip up the contents of the appManifest/ folder to create a manifest.zip or appManifest_Hub/ folder to create a appManifest_Hub.zip Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Upload a custom app")

Deploy to Teams

Start debugging the project by hitting the F5 key or click the debug icon in Visual Studio Code and click the Start Debugging green arrow button.

NOTE: First time debug step

On the first time running and debugging your app you need allow the localhost certificate. After starting debugging when Chrome is launched and you have installed your app it will fail to load.

• Open a new tab in the same browser window that was opened
• Navigate to https://localhost:3000/tab
• Click the Advanced button
• Select the Continue to localhost

NOTE: Debugging

Ensure you have the Debugger for Chrome/Edge extension installed for Visual Studio Code from the marketplace.
