usePortal Hook

The usePortal hook facilitates the creation and management of portal components in React applications. Portals provide a first-class way to render children into a DOM node that exists outside the DOM hierarchy of the parent component. This hook is particularly useful for rendering modals, dropdowns, and tooltips.

Features

• Dynamic Portal Creation: Automatically creates and manages a DOM element for the portal.
• Simple State Management: Provides functions to open and close the portal, along with a state variable to track its visibility.
• Easy Integration: Can be integrated seamlessly with existing React components.

Usage

Import the usePortal hook and use it in your React components to manage portals:

1import { usePortal } from '@custom-react-hooks/all';
2
3const PortalComponent = () => {
4  const { openPortal, closePortal, isOpen } = usePortal();
5
6  return (
7    <div>
8      <button onClick={openPortal}>Open Portal</button>
9      <button onClick={closePortal}>
10        Close Portal
11      </button>
12      {isOpen && <div className="modal">This is portal content</div>}
13    </div>
14  );
15};
16
17export default PortalComponent;

In this example, the usePortal hook is used to render a modal-like component. The portal can be opened and closed using the provided functions.
