Import Components to MDX
In a Next.js project using MDX, you can import custom components directly into your MDX files to enhance the rendering of Markdown content. This allows you to use React components within your Markdown documents, providing dynamic and interactive elements.
Example: Importing a Button Component
markdownimport { Button } from "@/components/ui/button";
<div className="pb-4">
<Button>Click Me</Button>
</div>
Other components can be imported and used within MDX files by customizing the rendering behavior. The useMDXComponents
function is a custom hook designed to provide custom React components for rendering MDX (Markdown with JSX) content. This function allows you to override the default MDX components with your own, providing custom styling and behavior.
The mdx-components.tsx
file is created to define and provide custom React components for rendering MDX content. This file ensures that when MDX``files are processed, the elements within those files are rendered using the specified custom components rather than the default ones. For example, you can create a customh1
component that adds a specific style to all level 1 headings in your MDX files. You can also define custom components for code blocks, inline code, and other Markdown elements. These elements can be styled using Tailwind CSS or other styling frameworks to match your website's design.
tsx// Path: /mdx-components.tsx
import React from "react";
import type { MDXComponents } from "mdx/types";
import YouTube from "@/components/mdx/youtube";
import Code from "@/components/mdx/code";
import InlineCode from "@/components/mdx/inline-code";
import Pre from "@/components/mdx/pre"; // Adjust the import path as needed
import { Button } from "@/components/ui/button";
export function useMDXComponents(components: MDXComponents): MDXComponents {
return {
...components,
YouTube,
pre: Pre, // Use the custom Pre component
code: (props) => {
const { className, children } = props;
if (className) {
return <Code {...props} />;
}
return <InlineCode>{children}</InlineCode>;
},
h1: (props) => <h1 className="text-4xl font-black pb-4" {...props} />,
h2: (props) => <h2 className="text-3xl font-bold pb-4" {...props} />,
h3: (props) => <h3 className="text-2xl font-semibold pb-4 " {...props} />,
h4: (props) => <h4 className="text-xl font-medium pb-4" {...props} />,
h5: (props) => <h5 className="text-lg font-normal pb-4" {...props} />,
h6: (props) => <h6 className="text-base font-light pb-4" {...props} />,
p: (props) => <p className="text-lg mb-4" {...props} />,
li: (props) => <li className="pb-1" {...props} />,
ul: (props) => <ul className="list-disc pl-6 pb-4" {...props} />,
ol: (props) => <ol className="list-decimal pl-6 pb-4" {...props} />,
hr: (props) => <hr className="my-4" {...props} />,
blockquote: (props) => (
<blockquote
style={{ paddingBottom: 0 }}
className="border-l-4 pl-4 my-4"
{...props}
/>
),
};
}
In the example above, the useMDXComponents
function is defined to provide custom components for rendering MDX content. The function takes the default MDX components as an argument and returns an object with the custom components. The custom components include a custom YouTube
component, Code
component, InlineCode
component, Pre
component, and custom styling for headings, paragraphs, lists, blockquotes, and horizontal rules.
To use the custom components in your MDX files, you need to import the useMDXComponents
function and pass it to the `
component provided by
@mdx-js/react`. This component wraps the MDX content and applies the custom components to the rendered elements.
