Enhancing Next.js SEO with 'use client' Metadata

Currently, I am facing an issue with my product page. The metadata for this page is fetched from the backend using an API that retrieves data from a database. To fetch this data and update it on the client side, I am utilizing a custom hook. However, the problem arises when trying to access this metadata using the "use client" directive.

Due to the complexity of the code (over 500 lines), I cannot share it all but here is a brief overview of what I am attempting:

"use client"
import React from "react";
import useGetData from "./useGetData";

const Page = () => {
   const { data } = useGetData();
   return (
      <div>
      Utilizing {data}
      </div>
   );
}

export default Page;

const GenerateMetaDataTags = () => {
  const { propId } = useParams();
  const { data, loading, error } = useGetData(propId);
  const metaData = {};

  data.forEach((ele) => {
    metaData[ele.name] = ele.content;
  });

  if (!loading) {
    return metaData;
  }
};

export const metadata = GenerateMetaDataTags();

The challenge lies in updating this data on the client side post-fetching from the database. Despite experimenting with various methods like layout.js, I must stick to using hooks to retrieve data from the database – which always requires the "use client" directive.

Answer №1

According to the documentation, it is not possible to create metadata within a client-side component.

Answer №2

Based on the code provided, it appears that you have successfully retrieved the meta data in the variable metadata. To ensure that this data is properly displayed, be sure to include it in the return statement of the Page method. Additionally, consider invoking GenerateMetaDataTags() before the return statement and removing the line:

export const metadata = GenerateMetaDataTags();
at the end. When referencing metadata, it seems to pertain to the information found within the meta tags intended for the Head component.

import Head from 'next/head'

...
...
const Page = () => {
   const { data } = useGetData();

   const metadata = GenerateMetaDataTags();

  return (
<>
    <Head>
      <meta name="viewport" content="width=device-width, initial-scale=1.0" />
      <meta name="msapplication-TileColor" content="#000000"/>
      <meta name="msapplication-config" content="/favicon/browserconfig.xml" />
      <meta name="ele1" content={metaData["ele1"]} />
      <meta name="ele2" content={metaData["ele2"]}/>
    </Head>

    <SomeComponent>
     <div>
      Utilization of {data}
     </div>
    </SomeComponent>

</>);
}
...
...

To delve deeper into rendering techniques, you can explore resources focusing on pages router or app router.

Answer №3

I have encountered a similar issue where I have tried various methods without any success. Currently, I am utilizing Next.js 14 along with MongoDB and dealing with multiple nested routes. The most effective approach to fetching the data is client-side using "useClient" for useEffect. While all pages function perfectly, the only setback lies in the SEO aspect. Since using 'useClient' within the app router prevents the utilization of export const metadata or the .

If only they had incorporated NextSEO or the head component, handling the SEO would have been much simpler.
