In a Next.js project, implementing Server-Side Rendering (SSR) for efficient data fetching can greatly enhance performance and improve SEO. To ensure that your data is pre-fetched on the server and passed to the client, you can follow these best practices:
1. Export a function named `getServerSideProps` in your page component. This function will be executed on the server every time the page is requested.
2. Inside the `getServerSideProps` function, use the appropriate method to fetch the data from your API or external source. It is recommended to use `fetch` or a package like `axios` for this purpose.
3. Parse the response data as needed. In your example, you're using `res.json()` to parse the response body as JSON.
4. Return an object with a `props` property inside the `getServerSideProps` function. This object will be passed as props to your page component.

To implement Server-Side Rendering (SSR) for efficient data fetching in a Next.js project, you can follow these best practices:
1. Use the `getServerSideProps()` function: Next.js provides a special function, `getServerSideProps()`, that allows you to fetch data on the server and pass it to the client. This function runs on every request, both server-side and client-side navigation.
2. Fetch data asynchronously: Inside the `getServerSideProps()` function, you can use `fetch()` or any other method to fetch data from your API or external sources. Make sure to use `await` for asynchronous requests.
3. Prepare and return the data in the `props` object: Once you have fetched the data, prepare it in a way that can be easily consumed by your component. Return the data within the `props` object.
4. Populate the component with the fetched data: In your component (in this case, `HomePage`), access the data from the props and render it accordingly.
