Building XMLtoMD: Real-Time XML Validation with Monaco Editor in Next.js

I recently launched XMLtoMD, a free XML to Markdown converter with professional code editor UX. In this post, I'll share how I implemented real-time XML syntax validation using Monaco Editor.

The Challenge

Most online converters use simple <textarea> elements. I wanted:

  • Syntax highlighting
  • Real-time error detection
  • Professional code editor feel
  • Split-screen live preview

Why Monaco Editor?

Monaco powers VS Code. Benefits:

  • Rich API for custom languages
  • Built-in error rendering
  • Familiar to developers
  • Excellent TypeScript support

Try It Yourself

XMLtoMD is completely free: https://xml-to-md.vercel.app/

What I Learned

  1. Monaco's API is powerful but documentation is sparse
  2. Web Workers essential for large file handling
  3. Developer UX matters more than feature count
