In a recent update, Next.js has introduced Server Components (SSCs) and Client Components to optimize rendering performance. SSCs render entirely on the server, sending only HTML to the client, while Client Components require JavaScript for interactivity. When combining these components, only the necessary JavaScript is sent, reducing bundle sizes and improving performance.
This approach enables developers to isolate interactivity JavaScript, achieving optimized performance and reduced bundle sizes. Additionally, templates allow for quick creation of reusable snippets or FAQs.
