# Windows 8 Platform Guide

This guide shows how to set up your SDK development environment to deploy Cordova apps in Windows 8. It shows how to use either shell tools specific to Windows 8 to generate and build apps, or the cross-platform Cordova CLI discussed in The Command-Line Interface. (See the Overview for a comparison of these development options.) This section also shows how to modify Cordova apps within Visual Studio. Regardless of which approach you take, you need to install the Visual Studio SDK, as described below.

See Upgrading Windows 8 for information on how to upgrade existing Windows 8 Cordova projects.

Cordova WebViews running on Windows 8 rely on Internet Explorer 10 as their rendering engine, so as a practical matter you can use IE10's powerful debugger to test any web content that doesn't invoke Cordova APIs. The Windows Phone Developer Blog provides helpful guidance on how to support IE10 along with comparable WebKit browsers.

## Requirements and Support

You need one of the following OS/SDK combinations, either from an installation disk or an ISO disk image file:

Apps compiled under Windows 8.1 do not run under Windows 8.0. Apps compiled under Windows 8.0 are forward-compatible with 8.1.

<!-- 64-bit necessary? Pro necessary? ELSE still recommended for parallel WP dev -->

Follow the instructions at windowsstore.com to submit the app to Windows Store.

<!-- true? -->

To develop Cordova apps for Windows 8, you may use a PC running Windows, but you may also develop on a Mac, either by running a virtual machine environment or by using Boot Camp to dual-boot a Windows 8 partition. Consult these resources to set up the required Windows development environment on a Mac:

## Using Cordova Shell Tools

If you want to use Cordova's Windows 8-centered shell tools in conjunction with the SDK, you have two basic options:

• Access them locally from project code generated by the CLI. They are available in the platforms/windows8/cordova directory after you add the windows8 platform as described below.

• Download them from a separate distribution at cordova.apache.org. The Cordova distribution contains separate archives for each platform. Be sure to expand the appropriate archive, cordova-windows8\windows8 in this case, within an empty directory. The relevant batch utilities are available in the top-level bin directory. (Consult the README file if necessary for more detailed directions.)

These shell tools allow you to create, build, and run Windows 8 apps. For information on the additional command-line interface that enables plugin features across all platforms, see Using Plugman to Manage Plugins.

## Install the SDK

Install the Ultimate, Premium, or Professional 2013 editions of Visual Studio.

## Create a New Project

At this point, to create a new project you can choose between the cross-platform CLI tool described in The Command-Line Interface, or the set of Windows 8-specific shell tools. From within a source-code directory, this CLI approach generates an app named HelloWorld within a new hello project directory:

    > cordova create hello com.example.hello HelloWorld
> cd hello
> cordova build


Here's the corresponding lower-level shell-tool approach:

    C:\path\to\cordova-win8\bin\create.bat C:\path\to\new\hello com.example.hello HelloWorld


## Build the Project

If you are using the CLI in development, the project directory's top-level www directory contains the source files. Run either of these within the project directory to rebuild the app:

    > cordova build
> cordova build windows8   # do not rebuild other platforms


If you are using the Windows Phone-specific shell tools in development, there is a different approach. Once you generate the project, the default app's source is available in the projects\windows8\www subdirectory. Subsequent commands are available in the cordova subdirectory at the same level.

The build command cleans project files and rebuilds the app. The first example generates debugging information, and the second signs the apps for release:

    C:\path\to\project\cordova\build.bat --debug
C:\path\to\project\cordova\build.bat --release


The clean command helps flush out directories in preparation for the next build:

    C:\path\to\project\cordova\clean.bat


## Open the Project in the SDK and Deploy the App

Once you build a Cordova app as described above, you can open it with Visual Studio. The various build commands generate a Visual Studio Solution (.sln) file. Open the file in the File Explorer to modify the project within Visual Studio:

The CordovaApp component displays within the solution, and its www directory contains the web-based source code, including the index.html home page:

The controls below Visual Studio's main menu allow you to test or deploy the app:

With Local Machine selected, press the green arrow to install the app on the same machine running Visual Studio. Once you do so, the app appears in Windows 8's app listings:

Each time you rebuild the app, the version available in the interface is refreshed.

Once available in the app listings, holding down the CTRL key while selecting the app allows you to pin it to the main screen:

Note that if you open the app within a virtual machine environment, you may need to click in the corners or along the sides of the windows to switch apps or access additional functionality:

Alternately, choose the Simulator deployment option to view the app as if it were running on a tablet device:

Unlike desktop deployment, this option allows you to simulate the tablet's orientation, location, and vary its network settings.

NOTE: Consult the Overview for advice on how to use Cordova's command-line tools or the SDK in your workflow. The Cordova CLI relies on cross-platform source code that routinely overwrites the platform-specific files used by the SDK. If you want to use the SDK to modify the project, use the lower-level shell tools as an alternative to the CLI.
