Developing JSS applications
JSS supports the latest version of Sitecore. Before getting started, identify the correct version of JSS for your Sitecore version.
You can create JSS applications using the latest version of the JSS sample applications (compatible with the latest version of Sitecore). To get started with JSS app development using the latest version of JSS sample apps and Sitecore, use one of the following guides:
If you do not have access to a Sitecore instance and are working in disconnected mode, use the Manifest API to define items and data in your JSS app. You can later import them to Sitecore with the help of the JSS CLI and the App Import API.
If you have access to a Sitecore instance, connect and deploy your application to Sitecore.
