Merges its props onto its immediate child.


  • Can be used to support your own `asChild` prop.

Install the component from your command line.

npm install @radix-ui/react-slot

Import the component.

import { Slot } from '@radix-ui/react-slot';
export default () => (

Use to create your own asChild API.

// your-button.jsx
import React from 'react';
import { Slot } from '@radix-ui/react-slot';
function Button({ asChild, ...props }) {
const Comp = asChild ? Slot : 'button';
return <Comp {...props} />;
import { Button } from './your-button';
export default () => (
<Button asChild>
<a href="/contact">Contact</a>

Any prop that starts with on (e.g., onClick) is considered an event handler.

When merging event handlers, Slot will create a new function where the child handler takes precedence over the slot handler.

If one of the event handlers relies on event.defaultPrevented make sure that the order is correct.

import { Slot } from '@radix-ui/react-slot';
export default () => (
<Slot onClick={(event) => { if (!event.defaultPrevented) console.log('Not logged because default is prevented.'); }}>
<button onClick={(event) => event.preventDefault()) />
