Teams Toolkit for Visual Studio Code update – January 2024

Junjie Li

Welcome to the latest update on Teams Toolkit for Visual Studio Code! In this release, we bring you a set of exciting new features, enhancements, and bug fixes to enhance your development experience.

New features

Deploy Tab Apps to Static Web App: We are thrilled to announce that Azure Static Web Apps is now the default solution for deploying Tab-based applications in Teams Toolkit. For those who prefer the older method using Azure Storage, you can refer to this sample.

Enhancements

• Clean up .deployment folder in between Deployments: Teams Toolkit now intelligently cleans up the .deployment folder in the build directory before each deployment. This not only addresses a known issue but also significantly reduces deployment time.
• Optimized Dev Tunnel Expiration: Inactive Dev Tunnel instances will now be automatically cleaned up after an hour, mitigating Dev Tunnel instance limitation errors.
• Log Level Settings: We’ve added log level settings to control the verbosity of Teams Toolkit logs. You can find these settings in the User and Workspace Settings under the Teams Toolkit section.
• Richer Information in Sample App Details Page: The Sample app detail page now includes additional details from the project README file, such as the project description, prerequisites, and steps to run the project.
• Improved Troubleshooting for Multi-tenant Scenario: Teams Toolkit now provides a troubleshooting guide for scenarios where the aadApp/update action fails with a HostNameNotOnVerifiedDomain error in multi-tenant setups.
• Optimized SPFx Solution Version Handling: Teams Toolkit now compares the SPFx solution version between global installations and the one used by Teams Toolkit when developers add additional web parts. Developers will be prompted if there’s a need to install or upgrade the solution version when differences are detected.

New additions to the Sample App Gallery

Teams Toolkit CLI v3.0.0 beta

Teams Toolkit CLI version 3 is now in public preview. Major changes include:

• New Command Signature: Teams Toolkit CLI now starts with teamsapp as the root command signature for more clarity. We recommend changing your scripts to use teamsapp as the command prefix.
• New Command Structure: Teams Toolkit CLI now has a new command structure that is more intuitive and easier to use. You can find the new command structure in the Teams Toolkit CLI Command Reference.
• New Doctor Command: teamsapp doctor is a new command that helps diagnose and fix common issues with Teams Toolkit and Teams application development.
