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.

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.

Interaction with app

Setup

1. Setup NGROK 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. Clone the repository

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

3. Install node modules

   Inside node js folder, navigate to samples/tab-channel-context/nodejs 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.

   npm install
   

4. Run the solution from the same path terminal using below command.

   npm start
   

5. Modify the manifest.json in the /appManifest folder and replace the following details

   • {{Manifest-id}} with some unique GUID. Refer GUID generator
   • {{base-url}} with base Url domain. E.g. if you are using ngrok it would be https://1234.ngrok-free.app and if you are using dev tunnels, your URL will be like: https://12345.devtunnels.ms.
   • <<Domain Name>> 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.app and if you are using dev tunnels then your domain will be like: 12345.devtunnels.ms.

6. Zip the contents of appManifest folder into a manifest.zip, and use the manifest.zip to deploy in app store or add to Teams.
