CSR (client-side rendering) (React.js)

SSR (Server-side rendering) (Next.js)

Server-side rendering makes HTML available to the client before JavaScript loads. Your site visitors can see and read your content even if it is not fully interactive. Server rendering eliminates the blank page problem. Rendered HTML also makes it easier for search engine and social media crawlers to consume your site.
