useClickOutside documentation
The useClickOutside hook is a custom React hook that allows you to listen for clicks outside a specified DOM element. This is particularly useful for scenarios where you want to close a component or trigger a specific action when the user clicks outside a specific element.
Type
import
import { useClickOutside } from '@pillar-ui/hooks'
Why useClickOutside
Managing click outside events can be a common task in React applications, and this hook provides an easy way to handle it in a consistent and reusable way.
Installation
To use useClickOutside in your project, you can install it from npm:
npm install --dev @pillar-ui/hooks
Usage
To use the useClickOutside hook in your React components, import it and call it in your functional component like this:
import { useState } from 'react'
import { useClickOutside } from '@pillar-ui/hooks'
function App() {
const [isOpen, setOpen] = useState(false)
const handleOutsideClick = () => {
setOpen(false)
}
const outsideRef = useClickOutside(handleOutsideClick)
return (
<div>
<button onClick={()=> setOpen(!isOpen)}>Toggle Menu</button>
{isOpen && (
<div ref={outsideRef} style={{ border: '1px solid black', padding: '10px' }}>
Click outside this box to close the menu.
</div>
)}
</div>
)
}
How It Works
The useClickOutside hook attaches a ref to the specified DOM element. It then listens for click events on the entire document. When a click event occurs, the hook checks if the event's target is outside the element referenced by the ref. If it's outside, the provided handler function is executed.
Use Case
The useClickOutside hook can be used in a variety of situations, such as:
- Toggling the visibility of an element when the user clicks outside of it.
- Closing a modal when the user clicks outside of it.
- Hiding a menu when the user clicks outside of it.
- Preventing the user from clicking on elements that they are not supposed to click on.
Implementation details
The useClickOutside hook uses the useRef and useEffect hooks from the React library to manage the boolean state value and update functions respectively.
TypeScript Support
This hook is written in TypeScript and provides type definitions for its usage
Troubleshooting
If you encounter any issues using the useClickOutside hook, please refer to the documentation or open an issue on the project's GitHub repository.
Conclusion
The useClickOutside custom hook is a useful tool for adding click outside functionality to your React application. By using this hook, you can make your app more accessible and improve the user experience for your users.
