Static content hosting

Azure DevOps Services

Choose to host static content for your extension, like HTML, CSS, and JavaScript files, on your own service, on a third-party hosting service, like Azure or Heroku, or on Azure DevOps Services directly.

Important

If your extension needs to create a custom table in the TFS database, do not create it using the 'dbo' schema. Instead, custom tables should be created in a separate schema. For example, 'YourExtensionName'.

Tip

For the latest extension development guidance, including theming and migration from VSS.SDK, see the Azure DevOps Extension SDK developer portal.

Host on Azure DevOps Services

In this model, static content is packaged with your extension's .vsix file and is served from a public endpoint at https://publisher.gallerycdn.vsassets.io.

Your extension's static content is useful when you're enhancing or decorating data from Azure DevOps Services. The extension pub doesn't require you (the extension publisher) to set up, manage, or pay for hosting services for your extension

Steps

  1. In your extension manifest file, specify the files you want to include through the files property: 
    {
  "files": [
    {
        "path": "scripts", "addressable": true
    },
    {
        "path": "images/extra/icon1.png", "addressable": true
    }
  ]
}
  2. Remove the baseUri property (if set) from your extension manifest.
  3. Package your extension (steps)
  4. Publish (or republish) your extension (steps)
> [!IMPORTANT] > Ensure to increment the version of your extension when you make changes to static content files included in your .vsix.

Keep in mind:

  • The value specified by the path attribute can be a folder or individual file. If a folder, the entire folder (and any subfolders) is included.
  • The addressable attribute is important and is what tells Visual Studio Codespaces to make the file(s) URL addressable.
  • All addressable asset requests are case-sensitive. If the request for an asset has a different case than the actual uploaded asset, it results in an HTTP 404 (Not found) error.
  • Not specifying a baseUri or setting an empty value tells Visual Studio Codespaces at runtime to calculate the base URI as if your static content's hosted by Azure DevOps Services.

Host on a third-party service

In this model, static content is served from your own service and not included in your extension's .vsix file.

Steps

  1. Set the baseUri property in your extension manifest For example, assuming a value of https://myservice.net/extension and this hub contribution:
    "baseUri": "https://myservice.net/extension",
    "contributions": [
        {
             "id": "Fabrikam.HelloWorld",
             "type": "ms.vss-web.hub",
             "targets": [
                 "ms.vss-work-web.work-hub-group"
             ],
             "properties": {
                 "name": "Hello",
                 "uri": "hello-world.html"
             }
         }
    ]

Azure DevOps Services loads the contents of this hub when it's rendered at https://myservice.net/extension/hello-world.html.
