ChatLifecycle Application

This sample illustrates Lifecycle of chat in Teams (Creating chat, adding members with all scenarios, deleting member).

Prerequisites

• Node.js version 10.14 or higher

  # determine node version
  node --version

• Ngrok (Only for devbox testing) Latest (any other tunneling software can also be used)

   # run ngrok locally
  ngrok http -host-header=localhost 3978

• Teams Microsoft Teams is installed and you have an account

To try this sample

• Clone the repository

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

• In a terminal, navigate to samples/graph-chat-lifecycle/nodejs

  cd samples/graph-chat-lifecycle/nodejs

• Install modules

  npm install

• Start the bot

  npm start

If you are using Visual Studio code

• Launch Visual Studio code
• Folder -> Open -> Project/Solution
• Navigate to samples\graph-chat-lifecycle\nodejs folder
• Select graph-chat-lifecycle\nodejs Folder

3. Run ngrok - point to port 3978 ngrok http -host-header=rewrite 3978

Register your Teams Auth SSO with Azure AD

1. Register a new application in the Azure Active Directory – App Registrations portal.
2. 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.
3. 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.
4. Under Manage, select Expose an API.
5. 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.io/00000000-0000-0000-0000-000000000000.
6. Select the Add a scope button. In the panel that opens, enter access_as_user as the Scope name.
7. Set Who can consent? to Admins and users
8. 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.
9. Ensure that State is set to Enabled
10. 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.io/00000000-0000-0000-0000-000000000000/access_as_user.
11. 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)
12. 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)
  • email
  • offline_access
  • OpenId
  • profile
  • Chat.Create
  • Chat.ReadWrite
  • ChatMember.ReadWrite
  • TeamsAppInstallation.ReadWriteForChat
  • TeamsAppInstallation.ReadWriteSelfForChat
  • TeamsTab.Create
  • TeamsTab.ReadWriteForChat
  • TeamsTab.ReadWrite.All
  • User.Read.All
• Click on Add permissions.

13. 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.io/auth/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

14. 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.

1. This step is specific to Teams.

   • Edit the manifest.json contained in the Manifest folder to replace your Microsoft App Id (that was created when you registered your bot earlier) everywhere you see the place holder string <<YOUR-MICROSOFT-APP-ID>> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json). Also, replace your Base url wherever you see the place holder string <<YOUR-BASE-URL>>.
   • Zip up the contents of the teamsAppManifest folder to create a manifest.zip
   • Upload the manifest.zip to Teams (in the Apps view click "Upload a custom app")

2. Update your config/default.json file

   • Replace the tab.id property with you Azure AD application ID.
   • Replace the tab.password property with the "client secret" you were assigned.
   • If you want to use a port other than 3978, fill that in here (and in your ngrok command)

Interacting with the app in Teams

1. In Teams, Once the app is successfully installed, it can be opened in the tab and has option to create group chat if user is authenticated.

2. Once create group chat is clicked, user will be able to add Title of the groupchat and select users from drop down to create a group chat and add members (using different scenarios) and delete member accordingly to depict the lifecycle of chat.

3. Also, Polly app will be installed to the created group chat and will be pinned to the chat.
