Sentiment Analysis for Teams chat messages using Azure Open AI and messaging extension.

This sample shows a feature where user can analyze sentiments for messages posted in Teams chat using messaging extension and Azure Open AI.

Included Features

• ME
• Azure Open AI For Sentiment Analysis

Interaction with app

Prerequisites

• Microsoft Teams is installed and you have an account (not a guest account)
• NodeJS
• dev tunnel or ngrok (For local environment testing) latest version (any other tunneling software can also be used).
• M365 developer account or access to a Teams account with the appropriate permissions to install an app.
• 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. In the env/.env.local file, fill all the required values for below and other values will be generated automatically once you debug/start the app.

SECRET_OPENAI_API_KEY=<<SECRET_OPENAI_API_KEY>>

Note: Open Api key is optional, if you dont have access to Azure Open Api Key.

SECRET_AZURE_OPENAPI_KEY=<Azure OpenAI Service Key>

CHAT_COMPLETION_MODEL_NAME=gpt-3.5-turbo

Note: If you are deploying the code, make sure that above mentioned values are properly updated at env/.env.dev or env/.env.dev.user wherever required.

1. Select Debug > Start Debugging or F5 to run the app in a Teams web client.
2. 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

Note these instructions are for running the sample on your local machine, the tunnelling solution is required because the Teams service needs to call into the bot.

1. 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

2. Setup for Bot

   In Azure portal, create a Azure Bot resource.

   • For bot handle, make up a name.
   • Select "Use existing app registration" (Create the app registration in Microsoft Entra ID beforehand.)
   • Choose "Accounts in any organizational directory (Any Azure AD directory - Multitenant)" in Authentication section in your App Registration to run this sample smoothly.
   • If you don't have an Azure account create an Azure free account here
   • In the new Azure Bot resource in the Portal, Ensure that you've enabled the Teams Channel
   • In Settings/Configuration/Messaging endpoint, enter the current https URL you were given by running the tunnelling application. Append with the path /api/messages

3. Clone the repository

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

4. In a terminal, navigate to samples/msgext-ai-sentiment-analysis/nodejs

5. Install modules

   npm install

6. Update the .env configuration for the bot to use the MicrosoftAppId, MicrosoftAppPassword,AzureOpenAPIKey and BaseUrl with application base url. For e.g., your ngrok or dev tunnels url. (Note the MicrosoftAppId is the AppId created in step 1 (Setup for Bot), the MicrosoftAppPassword is referred to as the "client secret" in step 1 (Setup for Bot) and you can always create a new client secret anytime.)

7. Run your app

   npm start

8. This step is specific to Teams.

   • Edit the manifest.json contained in the AppManifest folder to replace your Microsoft App Id (that was created when you registered your bot earlier) everywhere you see the place holder string <BOT_ID> (depending on the scenario the Microsoft App Id may occur multiple times in the manifest.json)

   • Also, update the <TEAMS_APP_ID> with unique Guid in manifest.json stored in (AppManifest).

   • Edit the manifest.json for validDomains 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.appand if you are using dev tunnels then your domain will be 12345.devtunnels.ms.

   • Zip up the contents of the AppManifest folder (AppManifest.admin and AppManifest.user folders separately) 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.)

Note: If you are facing any issue in your app, please uncomment this line and put your debugger for local debug.

Run command: teamsfx deploy --env dev.

Note: Provisioning and deployment may incur charges to your Azure Subscription.

Note: Once the provisioning and deployment steps are finished please update the manifest.json contained in the AppManifest folders (AppManifest.admin and AppManifest.user folders) for validDomains with base Url domain. E.g. if your deployed web app service URL is: https://botaxxxxx.azurewebsites.net/ then your domain-name will be botaxxxxx.azurewebsites.net.

Also, make sure that below key/values are properly added to the configuration section of web app after code deployement.

"name": "AZURE_STORAGE_CONNECTION_STRING", "value": 'DefaultEndpointsProtocol=https;AccountName=<Storage Account Name>;AccountKey=<Your Account Key>;EndpointSuffix=core.windows.net'
