🚀 Intro

As JavaScript frameworks gain popularity, so does the amount of client-side JavaScript rendering. But is this approach always optimal? In this video, we'll delve into the different rendering options offered by Next.js and when to use them to optimize performance.

🎨 Rendering
Before diving in, let's understand rendering and its various methods:

Client Side Rendering (CSR)
Server Side Rendering (SSR)
Static Site Generation (SSG)

💻 Client Side Rendering
CSR is ideal for dynamic content and DOM manipulations. However, it can lead to delayed page rendering and higher resource usage. Use CSR for dynamic components like carousels but beware of its impact on SEO and initial page load.

🖥️ Server Side Rendering
SSR shifts rendering to the server, delivering fully rendered pages populated with dynamic content. It's perfect for pages with relatively static content and improves SEO. However, frequent updates can impact performance, and faster servers may be needed to handle high traffic.

🏗️ Static Site Generation
SSG generates static HTML at build time, improving performance and SEO. While great for static content, it may lead to lengthy build times for larger applications and outdated data for frequently updated pages.

🔁 Incremental Static Regeneration (ISR)
ISR allows for dynamic updates to static content without redeploying. It combines the benefits of static generation with on-demand page generation, enhancing performance, reducing backend load, and accelerating builds.

Next.js offers versatile rendering methods that can be tailored to suit specific needs. Whether you choose CSR, SSR, SSG, or ISR, understanding when to use each method is key to optimizing your Next.js application's performance.
