|
[React components](https://react.dev) are a powerful way to create interactive and reusable elements in your documentation.
|
|
|
|
## Using React components
|
|
|
|
You can build React components directly in your `MDX` files using [React hooks](https://react.dev/reference/react/hooks).
|
|
|
|
### Example
|
|
|
|
This example declares a `Counter` component and then uses it with `<Counter />`.
|
|
|
|
```mdx
|
|
export const Counter = () => {
|
|
const [count, setCount] = useState(0)
|
|
|
|
const increment = () => setCount(count + 1)
|
|
const decrement = () => setCount(count - 1)
|
|
|
|
return (
|
|
<div className="flex items-center justify-center">
|
|
<div className="flex items-center rounded-xl overflow-hidden border border-zinc-950/20 dark:border-white/20">
|
|
<button
|
|
onClick={decrement}
|
|
className="flex items-center justify-center h-8 w-8 text-zinc-950/80 dark:text-white/80 border-r border-zinc-950/20 dark:border-white/20"
|
|
aria-label="Decrease"
|
|
>
|
|
-
|
|
</button>
|
|
|
|
<div className="flex text-sm items-center justify-center h-8 px-6 text-zinc-950/80 dark:text-white/80 font-medium min-w-[4rem] text-center">
|
|
{count}
|
|
</div>
|
|
|
|
<button
|
|
onClick={increment}
|
|
className="flex items-center justify-center h-8 w-8 text-zinc-950/80 dark:text-white/80 border-l border-zinc-950/20 dark:border-white/20"
|
|
aria-label="Increase"
|
|
>
|
|
+
|
|
</button>
|
|
</div>
|
|
</div>
|
|
)
|
|
}
|
|
|
|
<Counter />
|
|
```
|
|
|
|
export const Counter = () => {
|
|
const [count, setCount] = useState(0)
|
|
|
|
const increment = () => setCount(count + 1)
|
|
const decrement = () => setCount(count - 1)
|
|
|
|
return (
|
|
<div className="flex items-center justify-center">
|
|
<div className="flex items-center rounded-xl overflow-hidden border border-zinc-950/20 dark:border-white/20">
|
|
<button
|
|
onClick={decrement}
|
|
className="flex items-center justify-center h-8 w-8 text-zinc-950/80 dark:text-white/80 border-r border-zinc-950/20 dark:border-white/20"
|
|
aria-label="Decrease"
|
|
>
|
|
-
|
|
</button>
|
|
|
|
<div className="flex text-sm items-center justify-center h-8 px-6 text-zinc-950/80 dark:text-white/80 font-medium min-w-[4rem] text-center">
|
|
{count}
|
|
</div>
|
|
|
|
<button
|
|
onClick={increment}
|
|
className="flex items-center justify-center h-8 w-8 text-zinc-950/80 dark:text-white/80 border-l border-zinc-950/20 dark:border-white/20"
|
|
aria-label="Increase"
|
|
>
|
|
+
|
|
</button>
|
|
</div>
|
|
</div>
|
|
)
|
|
}
|
|
|
|
The counter renders as an interactive React component.
|
|
|
|
<Counter />
|
|
|
|
## Importing components
|
|
|
|
You can import components from your `snippets` folder. Unlike regular React, you cannot import components from every `MDX` file. Reusable components must be referenced from files within the `snippets` folder. Learn more about [reusable snippets](/reusable-snippets).
|
|
|
|
### Example
|
|
|
|
This example declares a `ColorGenerator` component that uses multiple React hooks and then uses it in an `MDX` file.
|
|
|
|
Create `color-generator.jsx` file in the `snippets` folder:
|
|
|
|
```mdx /snippets/color-generator.jsx [expandable]
|
|
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)
|
|
})
|
|
}
|
|
|
|
return (
|
|
<div className="p-4 border dark:border-zinc-950/80 rounded-xl not-prose">
|
|
<div className="space-y-4">
|
|
<div className="space-y-2">
|
|
<label className="block text-sm text-zinc-950/70 dark:text-white/70">

|
|

|
|
max="360"
|
|

|
|
onChange={(e) => setHue(Number.parseInt(e.target.value))}
|

|
|
}}

|
|
hsl(${hue}, 100%, ${lightness}%))`,
|
|
}}
|
|

|
|
</label>
|
|
|
|
<label className="block text-sm text-zinc-950/70 dark:text-white/70">

|
|
}}
|
|
/>
|
|
</label>
|
|
</div>
|
|
|
|
<div className="flex space-x-1">
|
|
{colors.map((color, idx) => (
|
|
<div
|
|
key={idx}
|
|
className="h-16 rounded flex-1 cursor-pointer transition-transform hover:scale-105"
|
|
style={{ backgroundColor: color }}
|
|
title={`Click to copy: ${color}`}
|
|
onClick={() => copyToClipboard(color)}
|
|
/>
|
|
))}
|
|
</div>
|
|
|
|
<div className="text-sm font-mono text-zinc-950/70 dark:text-white/70">
|
|
<p>
|
|
Base color: hsl({hue}, {saturation}%, {lightness}%)
|
|
</p>
|
|
</div>
|
|
</div>
|
|
</div>
|
|
)
|
|
}
|
|
```
|
|
|
|
Import the `ColorGenerator` component and use it in an `MDX` file:
|
|
|
|
```mdx
|
|
import { ColorGenerator } from "/snippets/color-generator.jsx"
|
|
|
|
<ColorGenerator />
|
|
```
|
|
|
|
The color generator renders as an interactive React component.
|
|
|
|
<ColorGenerator />
|
|
|
|
## Considerations
|
|
|
|
<AccordionGroup>
|
|
<Accordion title="Client-side rendering impact">
|
|
React hook components render on the client-side, which has several implications:
|
|
|
|
- **SEO**: Search engines might not fully index dynamic content.
|
|
- **Initial load**: Visitors may experience a flash of loading content before components render.
|
|
- **Accessibility**: Ensure dynamic content changes are announced to screen readers.
|
|
</Accordion>
|
|
<Accordion title="Performance best practices">
|
|
- **Optimize dependency arrays**: Include only necessary dependencies in your `useEffect` dependency arrays.
|
|
- **Memoize complex calculations**: Use `useMemo` or `useCallback` for expensive operations.
|
|
- **Reduce re-renders**: Break large components into smaller ones to prevent cascading re-renders.
|
|
- **Lazy loading**: Consider lazy loading complex components to improve initial page load time.
