An example of Dynamic APIs are Asynchronous

It has a little bit of new changes on how you access params on server side code(client as well) on Next.js 15.

export default async function MediaPage({
  params,
}: {
  params: {
    fileId: string;
  };
// you could destructure params like this
//assume it has path looks like /something/[fileId]/page.tsx
const fileId = params.fileId;

However, it is giving me a warning something like this

Server Error: Route “/galleries/[fileId]” used params.fileId. params should be awaited before using its properties. Learn more: https://nextjs.org/docs/messages/sync-dynamic-apis.

So Looking at new document, here is one way to avoid the warning and follow new style of using await.

export default async function MediaPage({
  params,
}: {
  params: Promise<{ fileId: string }>;
}) {
  const { fileId } = await params;
