Accessing a URL parameter outside the element in react-router-v6

Issue: I need to access a URL parameter outside the component in v6.

I know I can use the useParams() hook inside the component, But what if I needed to access a URL parameter outside the component?

This is how I used to do it in version 5:

// v5:
 
    <Route
        path = "/blog/:id" 
        render = {
            ({match:{params}}) => <Post item={ getPostById(params.id) } />
        }
    />

I am accessing the :id parameter outside the < Post /> component.

How can I write the previous code in v6?

With ({match:{params}}) => <Post item={ getPostById(params.id) } /> you've effectively written an anonymous React component that consumes a match prop and renders your Post component.

If you've components that can't use the useParams hook then write a wrapper function component that reads the id param from the useParams hook and passes the id along.

const PostWithIdParam = () => {
  const { id } = useParams();
  return <Post item={getPostById(id)} />;
};

...

<Route
  path="/blog/:id" 
  element={<PostWithIdParam />}
/>
