Static and Dynamic Rendering in NextJS

Rendering provides insights into how the content is actually generated and delivered to the users when they visit a website. In NextJS for example, offers both static and dynamic rendering so that developers can optimize applications in line with use cases, performance, SEO and experience.

Data fetching and rendering occur on the server at either build time (when you deploy) or when revalidating the data with static rendering.

Every time a user comes to your application, the cached result is served. Here are three advantages of static rendering.

• Faster Websites - Static rendering content can be cached and globally distributed. This ensures that users all around the world can view much faster and reliably the content on your website.
• Reduced Server Load - Since the content is being cached, your server is not required to dynamically create content in each request of the user.
• SEO - Prerendered content is easier for search engine crawlers to index, as it becomes available when a page loads. This may improve the search result rankings on these search engines.

It's helpful for UI that doesn't contain data or data common to the users, such as a static blog post or a simple product page. This might not be a perfect fit for something like a dashboard with much personalized data which is being updated quite often.

The content is rendered on the server for every user at request time-that is, when the user visits the page. With dynamic rendering, there are a couple of benefits.

• Realtime data : Dynamic rendering will enable your application to display realtime or frequently updated data. This is ideal where applications' data changes often.

• User specific content : It is more convenient to display pages with personal content, for example, dashboards or user profile information and refresh the data depending on the actions of users.
• Request Time Information : Dynamic rendering allows access to information that could only be known at request time, such as cookies or the search parameters in the URL.

1.Use Static Rendering when:

• Content changes infrequently.

• SEO demands fast load times.

• Scalability is a requirement.

2.Use Dynamic Rendering when:

• Content is constantly updated.

• There may be a need for personalized or real-time information.

• Specific data per user session is needed.

1. E-commerce Store

• Static: List of products (uses ISR for refreshing).
• Dynamic: User's cart, Products according to the user's preference.

2. Blog Platform

• Static: Blog posts use SSG.
• Dynamic: Comments Section- Using CSR/SSR.

3. User Dashboard

• Static: Pages which everyone can view such as About and Contact.
• Dynamic: These are the pages which contain user specific data. Uses SSR for every real-time update.

 NextJS provides you with multiple options for rendering, which range from full coverage to the requirements your project may be asking for, whether you are seeking static speed or dynamic flexibility. To build truly optimized applications that load faster, perform great and offer an ideal user experience, you have to understand the advantages and disadvantages of each option so that you can evaluate the type of your content and render it with an appropriate strategy to serve your users.
