• 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. 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.

To try this sample

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

1. Clone and start your sample sample

1. Clone the repository

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

2. In a terminal, navigate to samples/meetings-live-caption/nodejs

3. Install modules

   npm install

4. 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

5. Run your app

   npm start

2. Manually update the manifest.json

1. Manually update the manifest.json
   • Edit the manifest.json contained in the appManifest/ folder to replace the <<AppId>> with any guid value and <<APP-DOMAIN>> with with base Url domain. E.g. if you are using ngrok it would be 1234.ngrok.com and if you are using dev tunnels then your domain will be 12345.devtunnels.ms.
   • Zip up the contents of the appManifest/ folder to create a manifest.zip
   • Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Manage your apps -> Upload an app -> Upload a custom app")

NOTE: If you are unable to send caption, try configuring tab again.
