Offline Support Tickets

This sample app illustrates a classic CRUD application that operates offline within Microsoft Teams. Users can perform create, read, update, and delete operations without an internet connection. When the Android device reconnects to the internet, the app automatically syncs the locally stored data with blob storage. This ensures that all offline changes are updated and integrated into the central storage, maintaining data consistency across devices. The app effectively demonstrates handling data persistence and synchronization in environments with intermittent connectivity.

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

Microsoft Teams offline support tickets sample app: Manifest

Prerequisites

• NodeJS
• dev tunnel or ngrok latest version or equivalent tunnelling solution
• VS Code
• Blob Storage
• 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 Register you app with Azure AD.

1. Register a new application in the Microsoft Entra ID – 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 .env.
4. Under Manage, select Expose an API.
5. Select the Set link to generate the Application ID URI in the form of api://{base-url}/{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.
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-free.app/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)
  • profile
  • openid
  • offline_access
  • email
• Click on Add permissions. Please make sure to grant the admin consent for the required permissions.

13. 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 .env.

Setup

Note these instructions are for running the sample on your local machine.

1. Run ngrok - point to port 3000

   ngrok http 3000 --host-header="localhost:3000"

   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 3000 --allow-anonymous

2. Clone the repository

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

3. We have two different solutions to run, so follow below steps:

• In a terminal, navigate to samples/tab-support-offline/nodejs/server folder, Open your local terminal and run the below command to install node modules. You can do the same in Visual studio code terminal by opening the project in Visual studio code

  npx nodemon index

• The server will start running on 8080 port

• In a different terminal, navigate to samples/tab-support-offline/nodejs/client folder, Open your local terminal and run the below command to install node modules. You can do the same in Visual studio code terminal by opening the project in Visual studio code

  npm run start

• The client will start running on 3000 port

4. Open blobStoreOperations.js file from this path folder samples\tab-support-offline\nodejs\server\ and update:
   • {{ account-Name }} - Replace these values with your Azure Storage account details
   • {{ container-Name }}

This step is specific to Teams:

• Edit the manifest.json contained in the appManifest folder to replace every instance of the placeholder string {{YOUR-MICROSOFT-APP-ID}} with your Microsoft App Id (created during bot registration).

• Edit the manifest.json for {{domain-name}} with base Url 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.

• Zip up the contents of the appManifest folder to create a manifest.zip (Make sure that zip file does not contains any subfolder otherwise you will get error while uploading your .zip package)

• Upload the manifest.zip to Teams (In Teams Apps/Manage your apps click "Upload an app". Browse to and Open the .zip file. At the next dialog, click the Add button.)

• Add the app to personal static tabs.
