#How to hydrate components passed to MDX <Content>

I want to swap out the built-in markdown <pre> component like so:

<Content components={{ pre: MyPreComponent }} />

This renders the markup correctly, but the component is not interactive. How would I make it hydrate those components?

Hi @candid wolf. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To hydrate components passed to the MDX <Content> in Astro, you need to ensure that your custom component is a client-side component. This means it should be a JavaScript-based component (like React, Vue, Svelte, etc.) and not an Astro component (.astro file), as Astro components are server-rendered and do not have interactivity.

Here's an example of how you might do this with a React component:

import { h } from 'preact';
import { MyPreComponent } from '../components/MyPreComponent';

// ...

<Content components={{ pre: MyPreComponent }} />

In this example, MyPreComponent is a React component that will be hydrated on the client-side, allowing it to have interactivity.

Please note that the code snippets provided are based on the information extracted from the sources and may need to be adjusted based on your specific use case and project setup.

For more information, you can refer to the Astro documentation on MDX integration (https://docs.astro.build/en/guides/integrations-guide/mdx/) and Markdown content (https://docs.astro.build/en/guides/markdown-content).

@candid wolf kapa.ai is still learning and improving, please let us know how it did by reacting below

@magic steeple
It already is a React component

// components/Pre.tsx

import { useEffect } from "react";

export function Pre({ children, ...rest }: React.ComponentProps<"pre">) {
    useEffect(() => {
        console.log("hello");
    }, []);

    return <pre {...rest}>{children}</pre>;
}

This should print to the console after hydration, but I don't see anything in the console

Let me check the knowledge base for you. One moment! :books:

Based on the information provided in the extracts, it seems like you're trying to hydrate a React component in Astro. However, the extracts do not provide specific information on how to hydrate components passed to MDX <Content> in Astro.

Astro does provide several different tools to help you troubleshoot and debug your code. You can use console.log() to debug your Astro code. A console.log() statement in Astro frontmatter will always output to the terminal running the Astro CLI. Code that is written or imported inside of an Astro <script> tag is run in the browser. Any console.log() statements or other debug output will be printed to the console in your browser. This can be useful for debugging differences between the SSR output and the hydrated components in the browser. Source (https://docs.astro.build/en/guides/troubleshooting#_top)

However, for a more specific solution to your problem, I would recommend checking the Astro documentation or reaching out to the Astro community for further assistance.
