Can mdxJsxFlowElement have phrasing content as child?

[clemyan]

I am currently writing a markdown plugin in TypeScript to process MDX and have encountered a problem:

• If I enter <div>Hello <span>World</span></div> into the playground to check the mdast tree, we can see an mdxJsxFlowElement having mdxJsxTextElement and text as children.
• But neither the spec nor the TypeScript types allows mdxJsxTextElement and text to be children of mdxJsxFlowElement

So which of the two is correct? Or am I missing something?

Hi!

What are you doing and why? Perhaps markdown is not what you care about, perhaps you care about HTML.
I would recommend not checking for one or the other, but checking for both. TS should be smart enough to understand that content can then be both too.
Is this a problem with the playground or with actual code you have?

The spec/types you link is about the earliest parser integration.
MDX itself later does more things. Notably remarkMarkAndUnravel in https://github.com/mdx-js/mdx/blob/main/packages/mdx/lib/core.js is likely doing what you see.
