SuiteCommerce Web Stores | Aconcagua

Before you can create an extension, you must download the extension developer tools and extract them to create a top-level development directory. This is where you maintain all of your extension’s JavaScript, SuiteScript, Configuration, HTML, Sass, and assets. You use the tools to run Gulp.js commands to build baseline files for your extension, test your changes locally, and deploy extensions to NetSuite.


These tools are required for all SuiteCommerce site and any SCA sites implementing the Aconcagua release or later. You build extensions to interact with the Extensibility API to extend the application. See Extensibility Component Classes for an explanation of what components are currently accessible using the Extensibility API.

To download and extract the extension developer tools:

  1. Login to your NetSuite account.

  2. In NetSuite, go to Documents > Files > File Cabinet.

  3. Navigate to SuiteBundles/Bundle 248721/.

  4. Download the .zip file you find there:

  5. Extract the .zip file to a location in your local environment. This becomes your root development directory for custom themes.

    The .zip file extracts into a directory named ExtensionDevelopmentTools-18.2.1 by default, but you can rename this directory to suit your needs.


    SuiteCommerce theme and extension developers must use the SuiteCommerce Extension Management Bundle 2018.2.1 release to create themes and extensions for SuiteCommerce and the 2019.1 release of SuiteCommerce Advanced. Refer to the Commerce Applications for more information on next steps.

  6. Open a command line or terminal window.

  7. Access your root development directory created previously.

  8. Enter the following command to install additional Node.js packages into this directory:

    npm install


    This command installs the dependencies required to manage your custom extensions. These files are stored in the node_modules subdirectory of the root development directory. This command may take several minutes to complete.

  9. If you are implementing the 2019.1 release of SuiteCommerce Advanced and you want to use the theme and extension developer tools, follow instructions in Set Up SCA 2019.1 for Theme and Extension Developer Tools.

You are now ready to begin extension development. See Extension Developer Tools for information on building a baseline extension, testing on a local server, and deploying to a NetSuite account. For information on developing an extension, see Extensions.

If you also intend to create themes, you must Set Up Theme Developer Tools.
