With Sitecore 10, Sitecore has introduced Sitecore Headless Services (the artist formerly known as JSS Server Components) as a new means to do Sitecore development in a decoupled fashion.
Sitecore 10.0 made its way into the world a few weeks back and while it wasn’t a dramatic user-facing major release, it was a huge release for Sitecore becoming more cloud-native and looking ahead to the future of the Sitecore development experience.
