This sample demonstrates usage of Microsoft Graph to implement small group breakouts in a large Microsoft Teams meeting.

The sample is a web application built with React and Microsoft Graph Toolkit. The app can run as a web app in the browser, a personal or group tab app in Microsoft Teams, or a Progressive Web app on most modern desktop and mobile operating systems.

Watch the live stream where we showed how the app was built

• NodeJS
• A code editor - we recommend VS Code
• Office 365 Tenant and a Global Admin account - if you don't have one, get one for free here

In a terminal:

git clone https://github.com/microsoftgraph/meeting-moderator-sample

cd meeting-moderator-sample

npm install

npm start

The app will launch in your browser at http://localhost:3000. Sign in with your tenant credentials and consent to the permissions (make sure the user has ability to Admin consent).

The app will load the current signed in user's calendar with the option to moderate individual events.

Note: Only Microsoft Teams online meetings will be available for moderation. All other events will be grayed out.

The sample already contains a client id for an AAD application to allow you to get started immediately. However, we recommend creating your own so you have full control of the application.

To create your own AAD app and client id, follow the instructions in this blog post, under Register your application.

This step is required for the next section. The client id is defined in src\index.tsx

This sample is also a Microsoft Teams tab application and you can install it in your instance by following these instructions.

To install it in your Teams environment, Microsoft Teams requires the app to be publicly accessible using HTTPS endpoint. To accomplish this, you can use ngrok, a tunneling software, which creates an externally addressable URL for a port you open locally on your machine:

1. Install ngrok

   npm install -g ngrok

2. Ensure the app is running locally on http://localhost:3000. Start ngrok and attach it to port 3000

   ngrok http 3000

   This will generate a public url (similar to https://455709c1.ngrok.io) that you can use to access the app. You will use this url in your Teams manifest.

Now that ngrok is running, you need to add this url to your AAD application redirect urls. If you have not created a new AAD application, make sure you do that first before continuing (see section above).

To update the manifest, you will need to install the Microsoft Team Extension in VS code. Once you've installed the extension, open .publish/Development.env and replace the baseUrl0 with your ngrok url. Save the file.

Once the file is saved, the Development.zip package will be automatically updated. You can now use this package to install the application in Microsoft Teams:

1. In Microsoft Teams, click on Apps in the lower left corner

2. Click on Upload a custom app. This will open the file picker. Select Development.zip to install the application.

This sample also includes a helpful bot for helping the moderator keep track of questions from the attendees. See the bot branch for description and instructions on deploying and running the bot in your Azure Subscription.
