Create interactive examples and dynamic content in your documentation using familiar React hooks.

No imports needed! All standard React hooks are automatically available in your MDX files.

​
Available Hooks

You can use all standard React hooks in your documentation, such as useState, useEffect, and other React hooks.

​
Interactive Examples

​
Creating Components Directly in MDX

Create a component directly in your MDX file using React hooks to build interactive elements that respond to user actions:

A basic counter component created with useState hook

export const Counter = () => {
  const [count, setCount] = useState(0);
  
  return (
    <div>
      <p>Current count: {count}</p>
      <button onClick={() => setCount(count + 1)}>
        +
      </button>
    </div>
  );
}

<Counter />

​
Importing Components from Snippet Files

Import snippets into your MDX files to create reusable interactive components. Store snippets in the snippets folder for better organization. Learn more in the reusable snippets documentation.

​
Using React Hooks

​
Create a snippet file

Create a new file in the snippets folder with your component code.

/snippets/color-generator.mdx
export const ColorGenerator = () => {
  const [hue, setHue] = useState(180)
  const [saturation, setSaturation] = useState(50)
  const [lightness, setLightness] = useState(50)
  const [colors, setColors] = useState([])

  useEffect(() => {
    const newColors = []
    for (let i = 0; i < 5; i++) {
      const l = Math.max(10, Math.min(90, lightness - 20 + i * 10))
      newColors.push(`hsl(${hue}, ${saturation}%, ${l}%)`)
    }
    setColors(newColors)
  }, [hue, saturation, lightness])

  const copyToClipboard = (color) => {
    navigator.clipboard
      .writeText(color)
      .then(() => {
        console.log(`Copied ${color} to clipboard!`)
      })
      .catch((err) => {
        console.error("Failed to copy: ", err)
      })
  }

​
Import the snippet

Add an import statement at the top of your MDX file:

import { ColorGenerator } from "/snippets/color-generator.mdx"

​
Use the component

Add the component to your MDX content wherever needed:

<ColorGenerator />
