Extend functionality by creating Azure Data Studio extensions

Extensions in Azure Data Studio provide an easy way to add more functionality to the base Azure Data Studio installation.

Extensions are provided by the Azure Data Studio team (Microsoft), as well as the third-party community (you!).

Author an extension

If you're interested in extending Azure Data Studio, you can create your own extension and publish it to the extensions gallery.

Write an extension


To develop an extension, you need Node.js installed and available in your $PATH. Node.js includes npm, the Node.js Package Manager, which is used to install the extension generator.

To create your new extension, you can use the Azure Data Studio extension generator. The Yeoman extension generator is a beneficial starting point for extension projects. To start the generator, enter the following command in a command prompt:

npm install -g yo generator-azuredatastudio
yo azuredatastudio

For an in-depth guide on how to get started with your extension template, see keymap extension, which walks you through the creation of an extension.

Extensibility references

To learn about Azure Data Studio extensibility, see Extensibility overview. You can also see examples of how to use the API in existing samples.

Debug an extension

You can debug your new extension by using the Visual Studio Code extension Azure Data Studio Debug.

To debug your extension:

  1. Open your extension with Visual Studio Code.
  2. Install the Azure Data Studio Debug extension.
  3. Select F5, or select the Debug icon and then select Start.
  4. A new instance of Azure Data Studio starts in a special mode (Extension Development Host). This new instance is now aware of your extension.

Create an extension package

After writing your extension, you need to create a VSIX package that installs in Azure Data Studio. You can use vscode-vsce (Visual Studio Code Extensions) to create the VSIX package.

npm install -g @vscode/vsce
cd myExtensionName
vsce package
# The myExtensionName.vsix file has now been generated

With a VSIX package, you can share your extension locally and privately by sharing the .vsix file and using the command Extensions: Install From VSIX File from the command palette to install the extension in Azure Data Studio.

Publish an extension

To publish your new extension to Azure Data Studio:

  1. Add your extension to the extensions gallery.
  2. We currently don't have support to host third-party extensions. Instead of downloading the extension, Azure Data Studio has the option to browse to a download page. To set a download page for your extension, set the value of the asset Microsoft.AzureDataStudio.DownloadPage.
  3. Create a PR against release/extensions branch.
  4. Send a review request to the team.

Your extension will be reviewed and added to the extensions gallery.

Publish extension updates

The process to publish updates is similar to publishing the extension. Make sure the version is updated in package.json.
