Gray Matter in NextJS is a feature that helps optimize the React application by using server-side rendering (SSR). It pre-renders the pages before they are served to the client, which helps improve page loading speeds and user experience.
The gray matter feature in NextJS is an approach to pre-rendering and works by allowing the server to render a page before it is sent to the client. This means that the page is already constructed and rendered when it reaches the user's browser. This ensures that the page loads faster, as the HTML for the page is already loaded on the server before it reaches the user's browser.
Here are some benefits of using NextJS's Gray Matter feature for SSR:
•Faster loading times: Gray Matter pre-renders the pages before they are served to the user, making them load much faster.
•Improved user experience: Pre-rendering pages reduces page load times, improving the user experience overall.
•More efficient server use: Gray Matter pre-renders pages on the server, making the server use more efficient. It also helps ensure that the user’s browser isn’t doing all the hard work when it comes to rendering the page.
