Bridging two JSX runtimes: How we solved Astro's React children problem

Mintlify's Astro integration addresses the challenge of broken compound React components during hydration by ensuring React can maintain control over its component tree within Astro's MDX pipeline. The integration allows teams to manage their frontend stack while Mintlify handles content management, search, and AI features. The issue arose because Astro's JSX runtime compiled React children into Astro nodes, making them incompatible with React's need for dynamic interaction. Mintlify's solution involved extracting compound components before Astro's MDX compiler could alter them, preserving their integrity as React modules. This approach allows seamless integration of Mintlify's content engine with fully customizable frontends, ensuring that complex components like <Tabs> and <Accordion> function properly without affecting the authoring experience. The integration is now open-sourced, enabling teams to build custom doc frontends using Mintlify's robust content management capabilities.
