nextjs - 💡(How to fix) Fix Bug when trying to import a MDX page in a server component [3 comments, 3 participants]

Hello, I'm trying to build a blog with Next.js and MDX. I followed the tutorial on Next.js documentation and during the step to render MDX dynamically I get this error: I tried to create a client component where I import the MDX page the same way, but get an error because async await is not available in client components.

TL;DR

• Add the "use client" directive to the top of the file and refactor the code to handle asynchronous operations outside of client components.

Guidance

• Identify the components that require the use client directive and add it to the top of those files.
• Refactor the Page component to handle asynchronous operations, such as importing MDX pages, outside of the client component.
• Consider using a separate function or hook to handle the asynchronous import of MDX pages.
• Review the Next.js documentation on client components and server components to understand the limitations and best practices.

Example

// Use a separate function to handle the asynchronous import
const importMdxPage = async (slug: string) => {
  const { default: Post } = await import(`@/md/${slug}.mdx`)
  return Post
}

// Add the "use client" directive to the top of the file
'use client'

export default function Page({ params }: { params: { slug: string } }) {
  const { slug } = params
  const Post = importMdxPage(slug)

  return <Post />
}

However, the above example will still not work as expected because importMdxPage is an async function and Post will be a promise. A better approach would be to use a React state to store the imported component and update it when the import is complete.

Notes

• The provided code snippet is a simplified example and may not work as-is in the user's application.
• The use client directive is required for client components, but it also imposes limitations on the use of asynchronous operations.

Recommendation

• Apply workaround: Refactor the code to handle asynchronous operations outside of client components, and use a separate function or hook to handle the import of MDX pages. This will allow the user to work around the limitations of client components in Next.js.
