Type checking, completions and goto definition in VS Code in .md files?

[joostschuur-planetplay]

Is it possible at this point to get the full TypeScript IDE experience in Markdown files in a ```ts` block in Markdown files?

I've seem the reference to TypeScript in the docs, but if I have something like this in config.ts...

export const foo: string | undefined = undefined;

...and then in a Markdown file do this...

```ts
import { foo } from '../lib/config.js';
```

... the Markdown file doesn't know the type for foo.

Is this currently supported for Markdown files? Or is the point of ts/tsx code blocks right now just that you can import from .ts files and the types get stripped out?

Are there editor extensions that enable type checking in fenced code blocks? I have yet to find one for VSCode. Femaco seems to do that for neovim, but I haven't tried it.

Looks like there's TS in Markdown, but I haven't tried it.
