Serve Markdown to LLMs from your Next.js app (github.com)

Next.js has introduced a new feature called `next-md-negotiate`, enabling developers to serve Markdown content to large language models (LLMs) while continuing to serve HTML to traditional web browsers from the same URL endpoint. This solves the dilemma of maintaining separate endpoints for Markdown and HTML, which often leads to duplication and maintenance challenges. By using the HTTP `Accept` header, browsers receive standard HTML responses, whereas LLMs can request the Markdown version seamlessly, allowing for a more integrated and efficient server response process. This integration is significant for the AI/ML community as it streamlines how AI agents access web content, improving the efficiency of training and information retrieval without disrupting the user experience. Developers can now configure routes directly in their Next.js applications using the `mdConfig` array to define Markdown responses for various endpoints. The solution works with both App Router and Pages Router, ensuring compatibility across different Next.js versions. Overall, `next-md-negotiate` enhances the synergy between web applications and AI systems, facilitating better content delivery without sacrificing performance or user interaction.
