SharePoint Framework (SPFx) is a development model to build client-side solutions for Microsoft Teams and SharePoint. Your SPFx Teams app is hosted on Microsoft 365. It provides full support for developing and hosting your client-side SPFx solution. You can integrate your SharePoint Framework solution with:

SharePoint data and extend Microsoft Teams.
Your business APIs secured with Microsoft Entra ID.

For this tutorial, start Microsoft Teams app development with SPFx by building your first app with a tab capability.

Diagram showing this app has three features. Tab is highlighted.

Note

Teams Toolkit offers only the tab capability in a Teams app built with SharePoint Framework. The bot and message extension capabilities aren't available.

Prerequisites

4 minutes remaining

Here's a list of tools you need for building and deploying your apps.

	Install	For using...
Required
	Visual Studio Code	JavaScript or TypeScript, build environments. Use latest version.
	Teams Toolkit	A Microsoft Visual Studio Code extension that creates a project scaffolding for your app. Use Teams Toolkit v5.
	Node.js	Back-end JavaScript runtime environment. For more information, see Node.js version compatibility table for project type.
	Microsoft Edge (recommended) or Google Chrome	A browser with developer tools.
Optional
	Microsoft Graph Explorer	Microsoft Graph Explorer, a browser-based tool that lets you run a query from Microsoft Graph data.
	Developer Portal for Teams	Web-based portal to configure, manage, and distribute your Teams app including to your organization or the Microsoft Teams Store.

Tip

If you work with Microsoft Graph data, you should learn about and bookmark the Microsoft Graph Explorer. This browser-based tool allows you to query Microsoft Graph outside of an app.

Prepare development environment

After you install the required tools, set up the development environment.

Install Teams Toolkit

Microsoft Teams Toolkit helps simplify the development process with tools to provision and deploy cloud resources for your app and publish to the Teams Store.

You can use Teams Toolkit with Visual Studio Code or a command-line interface called TeamsFx CLI.

Visual Studio Code
Command Line

Open Visual Studio Code and select Extensions (Ctrl+Shift+X or View > Extensions).
In the search box, enter Teams Toolkit.
Select Install.

The Teams Toolkit icon appears in the Visual Studio Code Activity Bar.

You can also install Teams Toolkit from the Visual Studio Code Marketplace.

To install the TeamsFx CLI, use the npm package manager and enter the following command in Command prompt:

npm install -g @microsoft/teamsfx-cli

Depending on your configuration, you might need to use sudo to install the CLI:

sudo npm install -g --unsafe-perm @microsoft/teamsfx-cli

This condition is more common on Linux and macOS systems.

Ensure you add the npm global cache to your PATH. This step is normally done as part of the Node.js installer.

You can use the CLI with the teamsfx command. Verify that the command is working by running teamsfx -h.

Caution

Before you can run TeamsFx in PowerShell terminals, you must enable the remote signed execution policy for PowerShell.

Set up your Teams development tenant

A tenant is a space or a container for your organization in Teams, where you chat, share files, and run meetings. This space is also where you upload and test your app. Let's verify if you're ready to develop with the tenant.

Check for upload an app option

After creating your custom app, you must upload your app to Teams with the Upload a custom app option. Sign in to your Microsoft 365 account to check if this option is enabled.

The following steps help you verify if you can upload apps in Teams:

In the Teams client, select the Apps icon.
Select Manage your apps.
Select Upload an app.
Look for the option to Upload a custom app. If the option is visible, you can upload custom apps.

Note

If you don't find the option to upload a custom app, contact your Teams administrator.

Create a free Teams developer tenant (optional)

If you don't have a Teams developer account, join the Microsoft 365 developer program.

Go to the Microsoft 365 developer program.
Select Join Now and follow the onscreen instructions.
In the welcome screen, select Set up E5 subscription.
Set up your administrator account. After you finish, the following screen appears:
Sign in to Teams using the administrator account you just set up. Verify that you have the Upload a custom app option in Teams.

SharePoint Collection Site Administrator account

Ensure that you have an Administrator account for a SharePoint Site Collection. You need this account at deployment for hosting. If you're using a Microsoft 365 developer program tenant, you can use the administrator account you created at the time.

Now you’ve got all tools and set up your account. Next, let's set up your development environment and start building!

The Toolkit creates scaffolding for you in the project directory for the tab capability.

Among other items in this directory, the Teams Toolkit contains:

appPackage: contains the app icons, color.png and outline.png.
manifest.local.json: contains the app manifest for local debug.
manifest.json: contains the app manifest for publishing to Developer Portal for Teams.
.vscode/Settings.json: the settings you chose when creating the project.

As you selected an SPFx Web part project, the following files are relevant to your UI:

SPFx/src/webparts/{webpart}: contains your SPFx web part.
.vscode/launch.json: describes the debugging configurations available in the debug palette.

Build your tab app

2 minutes remaining

After you set up your project workspace with Teams Toolkit, build your tab project. You need to sign in to your Microsoft 365 account.

In this page, you learn to build and run your first app.

Use your Microsoft 365 account to sign in to Teams. If you're using a Microsoft 365 developer program tenant, the admin account you set up while registering is your Microsoft 365 account.

Visual Studio Code
Command line

Open Visual Studio Code.
Select the Teams Toolkit icon in the sidebar.
Select Sign in to M365.

Your default web browser opens to let you sign in to the account.
Sign in to your Microsoft 365 account using your credentials.
Close the browser when prompted, and return to Visual Studio Code.
Return to Teams Toolkit within Visual Studio Code.

The ACCOUNTS section of the sidebar shows your Microsoft 365 account name.

Now you're ready to build the app and run it locally!

    teamsfx account login m365

Your default web browser opens to let you sign in to the account. Sign in to your account using your credentials. Close the browser when you're prompted.

The account logins are shared between Visual Studio Code and the TeamsFx CLI.

Now that the development environment is configured, you can create, build, and deploy your first Teams app.

Build and run your app locally in Visual Studio Code

To build and run your app locally:

Select the Run and Debug icon from the Visual Studio Code sidebar.
Select one of the following options to run and debug the app.
- Teams workbench (Edge)
- Teams workbench (Chrome)
Select the play button or select the F5 key to start debugging.

Note

When you run the app for the first time, all dependencies are downloaded, and the app is built. A browser window automatically opens and loads the SharePoint Workbench when the build is complete. This process can take a few minutes to complete.

The Toolkit may prompt you to install a local certificate, if needed. This certificate allows Teams to load your application from https://localhost.
Select Yes when the following dialog appears:

Teams web client opens in a browser window.
Select Add when prompted to upload the custom app onto Teams on your local machine.
Select the web app version, if you're asked to switch to Teams desktop. You can see the HTML, CSS, and JavaScript code in a standard web development environment.
Select Load debug scripts, if you're prompted to load debug scripts before your custom app is uploaded in Teams.

Congratulations, your first app is running on Teams!

Your app should now be running. You can debug the app as any other SPFx web part (such as setting breakpoints).

Tip

Try placing breakpoints in the render method of SPFx/src/webparts/{webpart}/{webpart}.ts and reloading the browser window. Visual Studio Code will stop on breakpoints in your code.

Learn what happens when you use Local Workbench for debugging your app.

Local workbench is the default option to run and debug an app in Visual Studio Code. For this tutorial, it's recommended that you choose to debug your app with the Teams workbench, however, you can choose the Local workbench to explore web part layouts.

Note

This interface is intended only for exploring how a web part may appear in a mobile or a tablet. You would need to write the code for including them in your app, and then deploy it to view them.

To explore web part layouts using local workbench:

Select Local workbench, and then select F5 to run and debug the app.

The SharePoint Web Part Workbench opens in the browser to let you add, edit, and remove web parts.
Select Add Web Part in column one + icon to add your web part.
Select your web part from the menu.
Select Add a new section + icon to choose column layout for your web parts.
Use this interface to try out different layouts for web parts:
- View Web Part Data for your layout.
- Try changing between different layouts, text, color, and more.
- Use the Preview button to view the web parts.
- View the web part layout in different Mobile or Tablet devices.
- Save or discard any changes in the layout to continue trying possible layouts.
Close the browser window to stop local workbench debugging when you're ready.
