Server-side rendering (SSR) : Omnath Dubey

Server-side rendering (SSR) is a technique used in web development that involves generating the HTML markup for a web page on the server and sending it to the client's browser, as opposed to rendering it on the client-side using JavaScript. SSR can provide several benefits, such as faster initial load times, better search engine optimization (SEO), and improved accessibility.

In Next.js, SSR is built-in and can be used by default, making it easy to create server-rendered React applications. When a user requests a page, Next.js generates the HTML markup on the server and sends it to the client's browser, along with any necessary JavaScript and CSS files. This allows the page to be displayed to the user almost immediately, without waiting for all the JavaScript to load.

SSR can also improve SEO, as search engine crawlers can more easily index server-rendered pages. Additionally, SSR can improve accessibility, as it allows the content to be displayed to users who may have disabled JavaScript or are using assistive technologies that do not support client-side rendering.

One important thing to note is that SSR can come with some trade-offs, such as increased server load and reduced interactivity, since the user may need to wait for additional requests to be made to the server in order to interact with the page. However, Next.js also provides support for client-side rendering (CSR), which can be used when interactivity is needed.
