The provided text is a comprehensive tutorial on setting up a headless Content Management System (CMS) using Strapi to manage video content, which is then streamed through a Next.js frontend application. Unlike traditional CMSs where content and presentation are tightly coupled, a headless CMS like Strapi decouples the backend content from its frontend display, offering flexibility through API delivery. The guide details the process of configuring Strapi with Mux, a video hosting service, and using GraphQL to fetch data for the Next.js application. It involves setting up necessary plugins, creating API keys, and deploying the Strapi server so it can communicate with Mux via webhooks. The tutorial also includes steps for setting up a video player component in Next.js using Video.js, and demonstrates how to upload and manage video content through Strapi, which is then displayed on a web page. This approach exemplifies the growing popularity of headless CMSs due to their ability to support multiple frontends with a single backend, thus enhancing content management efficiency.
