Implementing Server-side Rendering with Next.js 14
Implementing server-side rendering (SSR) in your Next.js application is a powerful technique that enhances the performance and user experience of your web application. In this section, we will explore the steps required to implement server-side rendering with Next.js 14 and leverage the benefits it offers.
Understanding the Need for Server-side Rendering
Before diving into the implementation details, it's essential to understand why server-side rendering is beneficial for your application. Server-side rendering allows the server to pre-render the HTML content of a web page before sending it to the client. This results in faster initial page load times, improved SEO, and better user experience, especially on slower networks or devices.
By implementing server-side rendering in your Next.js application, you can ensure that the initial HTML content is readily available to users, reducing the time spent waiting for JavaScript to load and render the content on the client-side.
Creating Server-side Rendered Pages in Next.js
Next.js makes it straightforward to create server-side rendered pages in your application. By default, Next.js uses a hybrid rendering approach, where some pages are statically generated and others are server-rendered. You can control the rendering method for each page by using Next.js's page-level data fetching functions.
To create a server-side rendered page, you can export an async
function called getServerSideProps
from your page component. This function runs on the server and fetches the required data for the page. The data returned from this function is then passed as props to your page component.
For example, consider a page that displays a list of blog posts. You can define the getServerSideProps
function as follows:
export async function getServerSideProps() {
// Fetch data from Supabase or any other data source
const res = await fetch('https://api.example.com/posts');
const posts = await res.json();
// Return the data as props
return {
props: {
posts,
},
};
}
The posts
data will now be available as props in your page component, allowing you to render the content on the server and send it as HTML to the client.
Fetching Data from Supabase on the Server
To fetch data from Supabase on the server, you can utilize the Supabase client library within the getServerSideProps
function. This allows you to fetch data from Supabase and include it in the server-side rendered page.
For example, you can modify the previous getServerSideProps
function to fetch blog posts from Supabase:
export async function getServerSideProps() {
const supabase = createClient('YOUR_API_URL', 'YOUR_PUBLIC_KEY');
const { data: posts, error } = await supabase.from('posts').select('*');
return {
props: {
posts,
},
};
}
By leveraging the Supabase client library within the getServerSideProps
function, you can fetch data from Supabase on the server and include it in your server-side rendered page.
