good question

You can use this:

I normally don't recommend linting your mdx files, it's pain sometimes

have you tried it? @Happy champ

Id say mdx files should be for content only, custom components should be defined in a separate tsx file and imported in mdx (so in mdx you only have imported components and markdown content)

It didn't work on my end. I'm probably doing something wrong. But i'm looking more for typescript support in mdx anyway.

Currently working on a project that requires a bit more complexity in mdx files that uses getStaticProps to fetch data and display graph components

Seems server components don't work in mdx atm either?

Do you mean auto-complete for component props in MDX files? I guess you can use the official vscode plugin maintained by mdx-js: https://github.com/mdx-js/mdx-analyzer
I haven't used it though, I'm not sure if it is what you're looking for.

Depends on how you render MDX content, for Contentlayer, it doesn't work for server components for now.
The built-in next/mdx package supports RSC, you can read their guide to set up MDX for App Router.
