breadcrumber
The code defines a React component named Breadcrumber that uses the usePathname hook from Next.js to retrieve the current URL path (the pathname) of the page the user is on.
1. import { usePathname } from 'next/navigation';
- This imports the
usePathnamehook from Next.js, which is used to retrieve the current pathname of the URL. This is commonly used for things like rendering breadcrumbs, highlighting the current page, or tracking the navigation state in Next.js apps.
The usePathname hook is essential for components that need to access the URL path, such as breadcrumb navigations or dynamic routing logic.
2. export const Breadcrumber = () => {
- This defines a functional React component called
Breadcrumber. The component is likely intended to generate a breadcrumb navigation UI, but in this code, it currently doesn't render any visible UI.
The component is not yet fully implemented, as it only logs the pathname and does not render anything to the UI.
3. const pathname = usePathname();
- The
usePathnamehook is called to retrieve the current URL’s pathname (i.e., the part of the URL after the domain, which indicates the specific route or page the user is on). - For example, if the current URL is
https://example.com/products/123, thepathnamewould be/products/123. - The value of
pathnamewill be a string representing this path.
The pathname represents the part of the URL that follows the domain name and can be used to conditionally render content based on the current page.
4. console.log(pathname);
- The
pathnamevalue is logged to the browser’s console. This will help developers see the current path and debug or confirm the pathname value at runtime.
Logging the pathname is useful during development to understand how the component behaves in different routes.
5. return (<></>);
- The component returns an empty fragment (
<></>), meaning it doesn't render any visible content to the DOM. It seems like the component is incomplete, and perhaps the breadcrumb UI is planned to be added later.
Currently, this component does not display anything on the screen. The fragment <> </> indicates that it's a placeholder for future implementation.
This component logs the current URL’s pathname to the console whenever it’s rendered. The pathname is the part of the URL that follows the domain name, such as /about, /products/123, etc.
- When rendered, it calls
usePathnameto get the current pathname. - It logs that pathname to the browser's console.
- It doesn’t render any HTML to the screen.
In its current state, this component serves only as a debugging tool. It does not produce any visible UI.
