Next.js is a popular React framework that provides server-rendered React applications and various rendering techniques. However, please note that there might have been updates or changes since then. Here are the primary rendering techniques in Next.js:
1.Server-side Rendering (SSR):
Next.js allows you to perform server-side rendering by default. This means that when a user requests a page, the server generates the HTML content for that page and sends it to the user’s browser. This can help improve initial page load performance and search engine optimization (SEO) since search engines can index the fully rendered HTML content.
2.Static Site Generation (SSG):
Next.js also supports static site generation, where pages are pre-rendered during build time rather than on each user request. This is useful for content that doesn’t need to be personalized for each user. With SSG, the generated HTML files can be cached and served to users, resulting in faster loading times.
3.Client-side Rendering (CSR):
While Next.js emphasizes server-side rendering, you can still incorporate client-side rendering for parts of your application where real-time data updates or interactivity are required. Next.js seamlessly integrates with React components that use client-side rendering.
4.Incremental Static Regeneration (ISR):
This is a feature that Next.js introduced to combine the benefits of both server-side rendering and static site generation. With ISR, you can specify certain pages to be statically generated initially and then periodically re-generated at a specified interval. This is especially useful for dynamic content that needs to be updated but doesn’t require real-time updates.
5.Hybrid Rendering:
Next.js allows you to mix different rendering techniques within a single application. For example, you can use SSG for most pages but switch to SSR or CSR for specific components that require it.
