This sample demos a live coding in a Teams meeting stage using Live Share SDK. In side panel there is a list of question in specific coding language and on share click specific question with language code editor will be shared with other participant in meeting. Now any participant in meeting can write code for the question and same will be updated to all the other participants in meeting.

Interaction with app

Prerequisites

• Office 365 tenant. You can get a free tenant for development use by signing up for the Office 365 Developer Program.

• To test locally, NodeJS must be installed on your development machine (version 16.14.2 or higher).

• ngrok or equivalent tunnelling solution

Loading

Setup

1. Register a new application in the Azure Active Directory – App Registrations portal.

   • Your app must be registered in the Azure AD portal to integrate with the Microsoft identity platform and call Microsoft Graph APIs. See Register an application with the Microsoft identity platform.
   • You need to add following permissions mentioned in the below screenshots to call respective Graph API

NOTE: When you create app registration, you will create an App ID and App password - make sure you keep these for later.

2. Setup NGROK

   • Run ngrok - point to port 3978

   ngrok http -host-header=rewrite 3978

3. Setup for code

• Clone the repository

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

Install node modules

Inside node js folder, navigate to samples/meetings-live-code-interview/nodejs/api 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.

• Repeat the same step in folder samples/meetings-live-code-interview/nodejs/ClientApp

```bash
npm install
```

• We have two different solutions to run so follow below steps:

  A) In a terminal, navigate to samples/meetings-live-code-interview/nodejs/api

  B) In a different terminal, navigate to samples/meetings-live-code-interview/nodejs/ClientApp

• Run both solutions i.e. samples/meetings-live-code-interview/nodejs/api and samples/meetings-live-code-interview/nodejs/clientapp

  npm start
  

4. Setup Manifest for Teams

• 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 app registration earlier) 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.io then your domain-name will be 1234.ngrok.io.
  • Zip up the contents of the Manifest 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 the Apps view click "Upload a custom app")

  • Go to Microsoft Teams. From the lower left corner, select Apps
  • From the lower left corner, choose Upload a custom App
  • Go to your project directory, the ./Manifest folder, select the zip folder, and choose Open.
  • Select Add in the pop-up dialog box. Your app is uploaded to Teams.

Note Run the app on Teams with developer preview on.
