SiteGenesis JavaScript Controllers (SGJC) is a full-featured demonstration ecommerce reference application that enables you to explore Salesforce B2C Commerce and its capabilities. You can use it as the basis of your own custom site, although SFRA is recommended for new projects.
For developers, it provides sample code—pipelines, scripts, and ISML templates. For merchants, it offers sample configurations for catalogs, categories, products, and so on. See SiteGenesis Setup.
The demo instance is available with every realm. Open a browser and enter the URL for your sandbox, replacing the sub-domain name.
demo.web.yourcompanyname.demandware.net
You can get the SiteGenesis code in two ways.
Download the cartridge from Business Manager on your demo instance.
In Eclipse, use the Digital plug-in to create a new storefront cartridge.
You can use the code as the starting point for your own storefront and upload it to your Sandbox instance for customization or development.
