Tabs quick start Node.js

Tabs are Teams-aware webpages embedded in Microsoft Teams. A channel/group tab delivers content to channels and group chats, and are a great way to create collaborative spaces around dedicated web-based content.

Interaction with app

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)
• ngrok or equivalent tunneling solution
• M365 developer account or access to a Teams account with the

Setup

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

• In a terminal, navigate to samples/tab-channel-group-quickstart/js

• Install modules

  npm install

• Run your app

  npm start
  

4. Setup Manifest for Teams

• This step is specific to Teams.
  • Edit the manifest.json contained in the appPackage/ folder to replace with your MicrosoftAppId (that was created in step1.1 and is the same value of MicrosoftAppId in .env file) everywhere you see the place holder string {MicrosoftAppId} (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 appPackage/ folder to create a manifest.zip
  • Upload the manifest.zip to Teams (in the left-bottom Apps view, click "Upload a custom app")```

Deploy to Teams

Start debugging the project by hitting the F5 key or click the debug icon in Visual Studio Code and click the Start Debugging green arrow button.

NOTE: First time debug step

On the first time running and debugging your app you need allow the localhost certificate. After starting debugging when Chrome is launched and you have installed your app it will fail to load.

• Open a new tab in the same browser window that was opened
• Navigate to https://localhost:3000/tab
• Click the Advanced button
• Select the Continue to localhost

NOTE: Debugging

Ensure you have the Debugger for Chrome/Edge extension installed for Visual Studio Code from the marketplace.

Build for production

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
