Determining if the current URL in NextJS is the homepage

Determining if the current URL in NextJS is the homepage

Just getting started with NextJS.

I am trying to determine if the current URL is the home page.

When I use:

import { useRouter } from "next/router";

const router = useRouter();
const is_home = (router.pathname === '');

An error pops up on the frontend stating:

You have a Server Component that imports next/router. Use next/navigation instead.

If I switch from using:

import { useRouter } from "next/router";

To:

import { useRouter } from "next/navigation";

A terminal error occurs:

Error: useRouter only works in Client Components. Add the "use client" directive at the top of the file to use it.

Adding "use client" removes the terminal error, but then pathname in router.pathname displays as red in VS Code, showing the hover error as:

Property 'pathname' does not exist on type 'AppRouterInstance'.ts(2339)

I couldn't find any documentation for next/navigation like there is for next/router.

Is there a simpler method to check for the home page?

My goal is to set a default meta description for the home page and use the post excerpt as the meta description if the current URL is not the home page initially.

If you attempt to utilize the useRouter function in a component that is being displayed on the server-side, an error will occur. To rectify this issue, it is imperative to ensure that the component is exclusively displayed on the client-side.

An effective approach to achieve this is by employing the dynamic import feature from next/dynamic for asynchronous loading of the component on the client-side.

    import dynamic from 'next/dynamic';

    const DynamicComponent = dynamic(() => import('../components/MyComponent'), {
      ssr: false, // specify ssr as false to only render on the client-side
    });

Then proceed to render it conventionally as you would normally return jsx:

    return (   
          <DynamicComponent /> 
      );

Alternatively, if you wish to display this component on the serverside, utilize getServerSideProps like shown below:

    export async function getServerSideProps(ctx) {
      const isHome = ctx.req.url === '/';

      return {
        props: {
          isHome
        }
      };
    }

Subsequently, make use of the isHome prop in the following manner:

  const HomePage = ({ isHome })=> (
    <>
      { isHome ? <h1>Welcome to the home page!</h1>: <h1>This is not the home page.</h1>}
    </>
  )

  export default HomePage;
