Oracle by Example brandingInstall the Universal Windows Platform Development Tools

section 0Before You Begin

This 10-minute tutorial shows you how to configure your Windows 10 computer to develop Oracle JavaScript Extension Toolkit (Oracle JET) hybrid mobile applications that can be built as Universal Windows Platform (UWP) apps. This requires you to enable Developer Mode on your Windows 10 computer and to install an edition of Visual Studio 2017, an integrated development environment from Microsoft.


The Oracle JET command-line interface invokes the Windows SDK that you install with Visual Studio 2017 to build a UWP application from the source files of your Oracle JET hybrid mobile application. This application is then installed on your Windows 10 computer.

What Do You Need?

  • A Windows 10 computer

section 1Enable Developer Mode on Windows 10

Developer mode allows you to install any signed and trusted apps to your Windows 10 computer, whereas the default Windows 10 setting only permits the installation of apps from the Microsoft Store.

  1. Click the Start button and enter For developers in the Type here to search input field, then select For developers settings from the Best match list that appears.
  2. From the For developers settings dialog, choose Developer mode.
  3. Read the disclaimer in the dialog that appears and click Yes to accept the change.
    If your computer is owned by an organization, some options might be disabled. Contact your system administrator to enable Developer mode in this scenario.

section 3Create a System Environment Variable to Reference MSBuild Tools

  1. Click the Start button and enter Edit the system environment variables in the Type here to search input field, then select it from the Best match list that appears.
  2. In the System Properties dialog that opens, click Environment Variables, then click New in the System variables section of the Environment Variables dialog.
