In this example, we add an action to the query context menu in the work item queries hub.

Tip

Check out our newest documentation on extension development using the Azure DevOps Extension SDK.

Prerequisites for this article

You need to create a web app for your action, which can be found in the hub example.
If you haven't, take a look at the write your first extension tutorial to learn about the basics.

Update extension manifest file

Below is the code snippet that adds your action to the contributions section of your extension manifest.

...
    "contributions": [
        {
            "id": "myAction",
            "type": "ms.vss-web.action",
            "description": "Run in Hello hub action",
            "targets": [
                "ms.vss-work-web.work-item-query-menu"
            ],
            "properties": {
                "text": "Run in Hello hub",
                "title": "Run in Hello hub",
                "icon": "images/icon.png",
                "groupId": "actions",
                "uri": "action.html"
            }
        }
    ]
...

Learn about all of the places where you can add actions in Extensibility points.

Your HTML page

Your menu action is represented by a JavaScript script embedded in an HTML file. Save the following contents in a file and location that matches the reference to it in your extension's manifest file.

	<!DOCTYPE html>
	<html lang="en">
	<head>
		<meta charset="UTF-8">
		<title>Action Sample</title>
	</head>
	<body>
		<div>
			The end user doesn't see the content on this page.
			It is only in the background to handle the contributed menu item being selected.
		</div>
	</body>
	</html>

Your JavaScript

The script below registers the handler object to handle the action, place it in the head section of the previous HTML page.

We aliased lib to be node_modules/vss-web-extension-sdk/lib in our vss-extension.json manifest file.

<script src="lib/VSS.SDK.min.js"></script>
<script>
    VSS.init();

    // Use an IIFE to create an object that satisfies the IContributedMenuSource contract
    var menuContributionHandler = (function () {
        "use strict";
        return {
            // This is a callback that gets invoked when a user selects the newly contributed menu item
            // The actionContext parameter contains context data surrounding the circumstances of this
            // action getting invoked.
            execute: function (actionContext) {
                alert("Hello, world");
            }
        };
    }());

    // Associate the menuContributionHandler object with the "myAction" menu contribution from the manifest.
    VSS.register("myAction", menuContributionHandler);
</script>
