Sitecore JavaScript Services SDK (JSS) for SitecoreAI

Version:

The JavaScript Services SDK (JSS) enables developers to integrate SitecoreAI content with their front-end JavaScript applications. JSS includes APIs and services that fetch SitecoreAI data and uses it to build and deliver pages to site visitors using a JavaScript framework. It also provides seamless integration with other Sitecore products such as Personalize.

With JSS you can develop apps locally, quickly creating bespoke components before pushing your changes back to SitecoreAI so that marketers can use the latest components to build their customer experiences. You can test changes before publishing them by connecting your local host to the SitecoreAI Pages visual editor and fetching the latest data from your remote instance.

Using a starter kit template, you can immediately generate a new JSS app that you can customize to suit your business needs.

Warning

Sitecore JavaScript Services (JSS) SDK 22.x is in maintenance mode until June 2026. During this period, it will receive only critical bug fixes, dependency updates, and security patches.

After June 2026, JSS 22.x will reach end of life (EOL) and will no longer receive any updates or support.

To remain on a supported and actively maintained SDK, customers should upgrade to the Content SDK before June 2026. All new projects should use the Content SDK, as it is the recommended and fully supported option for Sitecore development.

Note

JSS is an open-source SDK under Apache 2.0 license. You are welcome to submit contributions to the public JSS repo via pull requests. The changelog lists updates grouped by version in chronological order, with unreleased changes at the top.
