Usage

const CustomComponent = () => {
    const elementInstance = useOnOutsideClick(() => alert('hello'))
    return <div ref={elementInstance}>
        <h1>Hello</h1>
    </div>
} 

useOnOutsideClick(func:function)

Fires passed function when click event triggers outside the target element

When we will use useOnOutsideClick in our functional components we have to pass it a function which will be called when click event triggers outside the target element. for e.g useOnOutsideClick(() => alert('hello'))

Also note when we call useOnOutsideClick it returns an elementInstance which is basically a ref which will be passed to the target element as a ref. This is how useOnOutsideClick tracks when the click event happens outside the element.

import useOnOutsideClick from 'on-outside-click-hook'

const CustomComponent = () => {
    const elementInstance = useOnOutsideClick(() => alert('hello'))
    // elementInstance will be passed to div as a ref
    return <div ref={elementInstance}>
        <h1>Hello</h1>
    </div>
}
