App Installation

This sample app demonstarte the installation lifecycle for Teams Apps which includes create, update delete Apps

Included Features

Tabs
Graph API

Interaction with app

Try it yourself - experience the App in your Microsoft Teams client

Please find below demo manifest which is deployed on Microsoft Azure and you can try it yourself by uploading the app package (.zip file link below) to your teams and/or as a personal app. (Sideloading must be enabled for your tenant, see steps here).

App Installation: Manifest

Prerequisites

Microsoft Teams is installed and you have an account (not a guest account)
To test locally, NodeJS must be installed on your development machine (version 16.14.2 or higher)
dev tunnel or ngrok latest version or equivalent tunneling solution
M365 developer account or access to a Teams account with the
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.

Ensure you have downloaded and installed Visual Studio Code
Install the Teams Toolkit extension
Select File > Open Folder in VS Code and choose this samples directory from the repo
Using the extension, sign in with your Microsoft 365 account where you have permissions to upload custom apps
Select Debug > Start Debugging or F5 to run the app in a Teams web client.
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.

Setup

Register a new application in the Microsoft Entra ID – 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
Setup for Bot

In Azure portal, create a Azure Bot resource.
Ensure that you've enabled the Teams Channel
While registering the bot, use https://<your_tunnel_domain>/api/messages as the messaging endpoint. NOTE: When you create app registration, you will create an App ID and App password - make sure you keep these for later.

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
```

Setup for code

Clone the repository

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

Update the .env configuration for the bot to use the ClientID and ClientSecret. (Note the MicrosoftAppId is the AppId created in step 1 (Setup for Bot), the MicrosoftAppPassword is referred to as the "client secret" in step 1 (Setup for Bot) and you can always create a new client secret anytime.)
In a terminal, navigate to `samples/graph-app-installation-lifecycle/nodejs
Install modules
```
npm install
```
Run your bot at the command line:
```
npm start
```

Setup Manifest for Teams

This step is specific to Teams.
- Edit the manifest.json contained in the ./appManifest 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-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.
- Zip up the contents of the appManifest 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 ./appManifest folder, select the zip folder, and choose Open.
- Select Add in the pop-up dialog box. Your app is uploaded to Teams.
