Prismic offers a headless page builder that enhances live editing with Next.js by utilizing a combination of the Page Builder, iframe bridge, and the Next.js website. This system allows content writers to manage and preview content in real-time using slices, which are sections of a page created as React components. The iframe bridge facilitates communication between the Page Builder and the Next.js website, enabling seamless content updates. The Next.js website incorporates a dedicated route, /slice-simulator, to render live previews, using the <SliceSimulator> component to listen for content updates and display them efficiently. The system employs techniques like storing content as URL parameters and using lz-string for compression to maintain server-side rendering capabilities. This integration offers a streamlined experience for developers and content creators, providing live editing functionality with minimal technical complexity, and is also adaptable for Prismic’s Nuxt and SvelteKit integrations.
