The Solution: Structured JSON

Editor.js outputs a clean JSON object. This means you can choose exactly how to render each block in React, giving you 100% control over your CSS and components.

  1. Security: No more dangerous inner HTML
  2. Flexibility: Render blocks differently on web and mobile
  3. Ease of use: Intuitive block-based interface for editors
