• Performance
• SEO (Search Engine Optimization)
• UX - SPA (Single Page Application)

• react, angular, vue
• routing between pages +
• The app feels more responsive and users do not see the flash between page navigations due to full-page refreshes.
• Fewer HTTP requests are made to the server, as the same assets do not have to be downloaded again for each page load.
• An application has a very complex UI with many pages/features
• An application has large and dynamic data
• Write preference of the site is more than reading
• The focus is on rich sites and a huge number of users

• nextjs, php, nuxtjs
• The initial page of the website load is faster as there are fewer codes to render.
• Good for minimal and static sites.
• Search engines can crawl the site for better SEO.
• An application has a very simple UI with fewer pages/features
• An application has less dynamic data
• Read preference of the site is more than write
• The focus is not on rich sites and has few users

The main difference between these two rendering approaches is in the algorithms of their operation. CSR shows an empty page before loading, while SSR displays a fully-rendered HTML page on the first load.

If you want to improve your Google visibility and rank high in the search engine results pages (SERPs), server-side rendering is the number one choice.

E-learning websites, online marketplaces, and applications with a straightforward user interface with fewer pages, features, and dynamic data all benefit from this type of rendering.

Client-side rendering is usually paired with dynamic web apps like social networks or online messengers. This is because these apps’ information constantly changes and must deal with large and dynamic data to perform fast updates to meet user demand.

The focus here is on a rich site with many users, prioritizing the user experience over SEO.

If your site’s content doesn’t require much user interaction, then SSR is more effective. It positively influences accessibility, page load times, SEO, and social media support.

On the other hand, CSR is excellent for providing cost-effective rendering for web applications, and it’s easier to build and maintain

System Requirements:

• Node.js 18.17 or later.
• macOS, Windows (including WSL), and Linux are supported. Automatic Installation We recommend starting a new Next.js app using create-next-app, which sets up everything automatically for you. To create a project, run:

npx create-next-app
