Visual Studio Services Web Extension SDK

Please refer to Azure DevOps Extension SDK instead of this repo!

Overview

Client SDK and TypeScript declare files for developing Visual Studio Team Services Extensions.

The core SDK script, VSS.SDK.js, enables web extensions to communicate to the host Team Services frame and to perform operations like initializing, notifying extension is loaded or getting context about the current page.

A previous version of the SDK was named vss-sdk. Make sure to switch to the new vss-web-extension-sdk name.

Get the SDK

Download and install Node.js
Run npm install vss-web-extension-sdk from the root of your extension project

This will place VSS.SDK.js and VSS.SDK.min.js in node_modules/vss-web-extension-sdk/lib/

Include the SDK script on your page

If you are developing a web extension, you will need to reference the SDK script from your HTML pages. For example:

<script src="lib/VSS.SDK.min.js"></script>

To ensure the SDK script is packaged with your extension, update your extension manifest (typically vss-extension.json) and add a new entry to files:

{
  "files": [
    {
      "path": "node_modules/vss-web-extension-sdk/lib",
      "addressable": true,
      "packagePath": "lib"
    }
  ]
}

Note: setting packagePath is optional, but results in a simpler path for referencing the SDK script from your HTML pages. Not setting a part name would have required you to reference the full path in your <script> tag (src="node_modules/vss-web-extension-sdk/lib/VSS.SDK.min.js")

Use the SDK

From your web extension's HTML page, include and initialize the VSS SDK like this:

<script>
  // Initialize
  VSS.init({
    usePlatformScripts: true,
    usePlatformStyles: true,
  });

  // Register callback to get called when initial handshake completed
  VSS.ready(function () {
    // Start using VSS
  });
</script>

Full API reference of VSS.SDK.js can be found at Core Client SDK page.

Types

Type definitions are provided for:

UI controls and client services (see typings/vss.d.ts)
REST clients and contracts for Build, Work, and Code (see typings/tfs.d.ts)
REST clients and contracts for Release Management (see typings/rmo.d.ts)

Dependency graph:

Consuming the types

From a TypeScript 2.5 or later project:

Set "moduleResolution": "node" in your tsconfig.json project file

See TypeScript Module Resolution for more details.

Alternatively, you can explicitly reference the types at the top of your TypeScript file(s):

/// <reference types="vss-web-extension-sdk" />

Organizing your web extension project

If you are developing a web extension for Visual Studio Team Service using TypeScript, we recommend the following organization:

Project structure

 |-- src
     |-- app.ts
     |-- some-module
         |-- a.ts
         |-- b.ts
 |-- static
     |-- css
         |-- main.css
     |-- images
         |-- logo.png
     |-- app.html
 |-- vss-extension.json
 |-- package.json
 |-- tsconfig.json

Place TypeScript source files in src
Place static content (CSS, images, HTML, etc) in static
- This simplifes the process of packaging all necessary static content in your

TypeScript project file (`tsconfig.json`)

Defines the options for compiling your TypeScript files.

{
  "compilerOptions": {
    "module": "amd",
    "moduleResolution": "node",
    "target": "es5",
    "rootDir": "src/",
    "outDir": "dist/",
    "types": ["vss-web-extension-sdk"]
  }
}

After compiling (tsc -p .), resulting .js files are placed in dist. For example, dist/app.js.
If your code directly uses types from other @types modules, you will want to include the module(s) in your package.json and add them to the types array. See @types.

NPM package manifest (`package.json`)

Declares the libraries (like the vss-web-extension-sdk) required to compile, package, and use your extension.

{
  /* other details like ID, version, etc are omitted */

  "scripts": {
    "build": "tsc -p .",
    "postbuild": "npm run package",
    "package": "tfx extension create",
    "gallery-publish": "tfx extension publish --rev-version",
    "clean": "rimraf ./dist && rimraf ./*.vsix"
  },
  "devDependencies": {
    "rimraf": "^2.5.4",
    "tfx-cli": "^0.3.45",
    "typescript": "^2.1.4"
  },
  "dependencies": {
    "@types/jquery": "^2.0.34",
    "@types/q": "0.0.32",
    "vss-web-extension-sdk": "^5.127.0"
  }
}

scripts provides a convenient way to define common operations that you want to perform on your project, like compiling and packaging.
- For example, to build (compile) and package your extension, run: npm run build. This runs build and postbuild. If you make a change that doesn't require compiling, you can package by simply running npm run package.
- To package and publish directly to the Marketplace on build, change the postbuild script to run the gallery-publish script (instead of package). You can then run npm run build -- --token xxxxxx (where xxxx is you personal access token for publishing to the Marketplace) to build, package, and publish your extension.
The dependencies on the @types for jquery and q are only necessary if your TypeScript code is directly referencing either of these types.

Extension manifest (`vss-extension.json`)

{
    /* details omitted */
    "files": [
        {
            "path": "dist",
            "addressable": true
        },
        {
            "path": "static",
            "addressable": true
        },
        {
            "path": "node_modules/vss-web-extension-sdk/lib",
            "addressable": true,
            "packagePath": "lib"
        }
    ],
    "contributions": [
        {
            "id": "my-hub",
            "type": "ms.vss-web.hub",
            "properties": {
                "name": "Hub",
                "uri": "static/app.html"
            }
        }
    ]
}

The compiled JavaScript files (placed into dist by your tsconfig.json) will be packaged into the dist folder of the extension package.
The VSS SDK scripts will be packaged into the lib folder of the extension package.
