In Next.js you can pass and access one or more property route params by the dynamic parameter name that you have set on. For example, pages/post/[postId]/[commentId].js would match /post/post-1/comments/comment-1.
pages/post/[postId]/[commentId].js => /post/post-1/comments/comment-1
Its query object would be:
{
postId: 'post-1',
commentId: 'comment-1'
}your Link component should be like this:
<Link
href="/post/[postId]/comments/[commentId]"
as={`/post/${postId}/comments/${commentId}`}
>
<a>Link to comment</a>
</Link>
