This repository is a Sitecore JSS 21.4 Next.js sample application created with npx create-sitecore-jss --templates nextjs,nextjs-sxa in which Storybook 7.4 was added step by step (see the commit history).
This was created for educational purposes, to show how common use cases and errors can be handled, and to serve as material for presentations.
I hope you will learn something new.
Enjoy!
