Tabs quick start

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.

Prerequisites

• NodeJS

• M365 developer account or access to a Teams account with the appropriate permissions to install an app.

Build and Run

In the project directory, execute:

npm install

npm start

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!

See the section about deployment for more information.
