Vega Studio is an extension for Visual Studio Code (VS Code) and Kiro. It includes these tools:
  • Integrated debugging tools
  • Real-time performance monitoring
  • Built-in app optimization features
  • Direct device management for Fire TV Stick
  • Testing capabilities
When you install the Vega SDK, the installer automatically configures Vega Studio in VS Code. If you use Kiro, install Vega Studio manually. Vega Studio gives you access to all Vega development tools and commands from the command palette in VS Code or Kiro.

​

  1. Open VS Code or Kiro, and look for the Vega extension icon in the activity bar.
  2. To check your installed extensions, go to Code > Settings > Extensions (VS Code) or Kiro > Settings > Extensions (Kiro), and enter “Vega Studio” in the Extensions: Marketplace search field. If you see the Vega extension icon, continue to Build Your App, or explore the Vega Studio panel and advanced configuration options. If you don’t see the Vega extension icon, continue to Install Vega Studio manually.

​
Manage your Vega projects

The Projects section lists your current projects with options to build, install, or run them. Screenshot of the Projects section in the Vega Studio panel showing a list of current projects with build, install, and run options.

​
Select your build mode

The Build Modes section lets you choose between Debug and Release builds for your Vega app. Your selection applies to all later builds until you change it. Screenshot of the Build Modes section showing the Debug and Release toggle options for configuring your Vega app build.

​
Debug mode

Debug mode is for development and testing. It includes debugging artifacts and enables the Metro Packager (React Native’s JavaScript bundler), which supports real-time code updates through Fast Refresh. Vega Studio automatically enables Fast Refresh when you use Debug mode. To use Fast Refresh:
  1. Build your app in Vega Studio.
  2. Run your app on Vega Virtual Device or a Fire TV device.
  3. Change your code, and confirm that the changes appear on your device.

​
Release mode

Release mode creates optimized, production-ready code for deployment and publishing. It disables development features such as Fast Refresh, removes debugging information, and reduces file size to improve runtime performance.

​
View your devices

The Devices section shows all virtual and physical devices connected to your computer. The device list updates automatically when you connect or disconnect a device. To run your project, select a device. Screenshot of the Devices section in the Vega Studio panel showing the context menu of available options for a connected device. From the device context menu, you can start a virtual device. Screenshot showing how to start a virtual device from the context menu on a device listing in the Devices section. You can also open a terminal session to interact with a device directly. Screenshot of the Devices section showing the context menu option that opens a terminal session for a connected device.

​
Install the Vega SDK manager to switch versions

The SDK Manager section lets you install a new SDK version, view installed SDK versions, or switch between installed versions. Screenshot of the SDK Manager section in the Vega Studio panel showing installed SDK versions and the options to install a new version or switch versions. To install a new SDK version:
  1. Select the SDK Manager section in the Vega Studio panel.
  2. Select Install New SDK or the + icon next to an available version.
  3. Wait for the installation to complete.
To switch SDK versions:
  1. Select the SDK Manager section in the Vega Studio panel.
  2. Select the version you want to activate.
  3. When prompted, reload VS Code or Kiro.
You can also manage SDKs from the command palette. For a full list of SDK Manager commands, see Vega Studio Commands.
