Teams CLI
Use the official Teams CLI (@microsoft/teams.cli) to create and manage the Teams app for this sample:
npm install -g @microsoft/teams.cli
teams --version
teams login
Expose this sample's local /api/messages endpoint with a tunnel, then create the Teams app:
teams app create --name "echo" --endpoint "https://<your-tunnel>/api/messages" --env .env --json
The CLI writes CLIENT_ID, CLIENT_SECRET, and TENANT_ID to your .env file and prints an install link for Teams.
Run
$: npm run dev
