Using Storybook and RSCs to build and test apps in isolation

Storybook 8 introduces experimental compatibility with React Server Components (RSCs), enabling developers to build, test, and document Next.js server applications in isolation. Traditionally focused on client-side rendering, Storybook now allows integration with RSCs, which are rendered on the server to enhance performance and user experience by reducing time-to-first-byte and improving page interactivity. This update broadens the scope of component-driven development and testing by addressing the challenges of representing dynamic, server-rendered components within Storybook's environment. The integration leverages the Mock Service Worker (MSW) add-on for simulating API responses, facilitating interactive testing of server-side components with realistic data. Despite its experimental status, this compatibility marks a significant step in adapting Storybook to the evolving landscape of server-rendered React applications.
