What are extensions?
What makes up an extension?
- A JSON manifest file contains basic info about the extension.
- Discovery assets - the markdown and images that make up your extension's overview and aesthetics in the marketplace.
- Static files that contain the logic of your extension, including HTML, JS, and CSS files. Static files are only applicable to contribution-based extensions.
All of these are bundled up to make a Team Extensions Service Package (.vsix file) that is published to the marketplace. From the marketplace, extensions can be installed directly by VSTS users.
What can you do with extensions?
There are dozens of places where you can add to the VSTS user interface, and we're adding more every sprint. Learn about all of the places where you can add a hub in the contributions reference.
- Provide new build and release tasks that teams can use in their builds.
- Use dashboard widgets to get custom views within VSTS.
- Extend the work item form with new tabs, sections, and actions.
- Create your own hub to embed new capabilities within our Agile, code, build, and test experiences.
- Develop actions that can be run on hubs, whether they're ours or ones you've created.
