The X in MDX - Rodrigo Pombo

A talk transcript exploring creative uses of MDX beyond simple component embedding. The speaker demonstrates how MDX's wrapper component exposes markdown content as React elements (JavaScript objects), enabling extraction and transformation of content at render time or build time. Examples include building a table of contents, step-by-step walkthroughs, scrollytelling layouts, and media-synchronized content. The talk itself was built using the same MDX technique, with steps synchronized to video timestamps. The key takeaway is that MDX can serve as a syntax extension for markdown, letting authors define custom dialects for any content type or layout.
