A complete guide to building a file-based MDX blog in Next.js 16 using next-mdx-remote — covering a typed data layer for reading posts from the filesystem, custom-styled MDX components, syntax highlighting, GitHub-flavored Markdown support, and per-post SEO metadata. Note: covers the setup as of publish; a follow-up guide addresses migrating to the actively maintained next-mdx-remote-client. Published on DevStacked, my developer blog covering practical Next.js and SaaS implementation guides.
