How to Preview MDX
Paste MDX content into the editor and the viewer renders a live preview alongside it. The preview updates as you type, showing how your headings, paragraphs, lists, code blocks, and other Markdown elements will look. JSX components are rendered as labeled stubs showing the component name and props, so you can verify your content structure without needing the actual component implementations. The viewer is useful for checking content layout, verifying frontmatter, and catching formatting issues before committing.
Frequently Asked Questions
Does the viewer render my custom components?
Custom JSX components are rendered as labeled placeholder stubs that show the component name and its props. This lets you verify content structure without needing the actual component code.
Does the preview update in real time?
Yes. The preview updates as you type with a short debounce to keep the editor responsive. Changes appear in the preview panel within a fraction of a second.
Can I preview MDX with frontmatter?
Yes. The viewer parses frontmatter and displays it separately from the rendered content, so you can verify both your metadata and your content in one view.
