Static Generation And Server Side Rendering_ Two Forms Of Next Js Pre-rendering

1. Static Generation And Server Side Rendering: Two Forms Of Next Js Pre-rendering. Currently, JavaScript enables developers to create three types of applications: pre-rendered webpages or static-generated sites, server-side rendered applications, and single-page applications (SPAs). Single-page applications involve several challenges. One of the primary challenges is Search Engine Optimisation. And in the current era, SEO drawbacks will lead to less visibility, reduced recognition in the market, and ultimately less revenue generation for a business. To avoid such complications, businesses rely mostly on static site generators and server-side rendering. Next, Js represents a React-based full-stack framework with integrated functionalities such as web pre-rendering.

2. So what's the difference? In traditional react, the whole application is loaded on the client. h However, with Next Js, the web page is rendered on the server. This translates into remarkable performance and value addition for SEO. This blog will discuss different types of pre-rendering. But before that, let us understand what pre-rendering is. What is web pre-rendering? By default, Next Js pre-renders all web pages. This indicates that, rather than depending on client-side JavaScript to download and render, Next Js Generate HTML for each web page in advance. What's the advantage? Instead of giving a blank screen, the users will be able to view the entire HTML content with the first load itself but without any interactivity unless the JavaScript is loaded. Prerender Nextjs Apps is responsible for generating all of the content within a web page. Pre-rendering enhances SEO because search crawlers can quickly detect and read the actual content and rank your webpage on the search results. Without a pre-render, the users will see a Blank Page unless the JavaScript is loaded. This will not just lead to disappointed users but also delay the access of content to search crawlers leading to poor SEO performance. Types of Pre-rendering in Next JS In Next JS, you will find three types of web pre-rendering: ● ● Static Site Generation (SSG) Server-Side Rendering Let's take a look at each of these types in detail. Static Site Generation (SSG) In static site generation (SSG), the HTML is generated at the build time. During each request, the pre-rendered HTML is used. In case an HTML page doesn't have any external data requirement, Prerender Nextjs Apps will pre-render its content by default. This is mostly applicable to About Us pages.

3. However, if the web page requires data fetching through an external API, the Next JS will then function as a component of the static generation process and will extract and download data in advance and generate the HTML. All these activities are completed during the build time. A CDN stores the entire pre-generated content. Therefore, whenever a user wants to see a web page, a cached version is processed and sent, leading to enhanced performance. Static site generation ( with or without data) is recommended during website generation whenever possible. This is because you can build a page just once and store it in CDN. Consequently, the entire page loading process becomes faster as compared to having a server render the webpage on each and every request. Static site generation is great for the following pages: ● ● ● ● Marketing pages Blog pages Help and documentation (privacy policy, business policy, etc.) E-commerce product listings However, static site generation might not be a great fit if web pre rendering is not possible before user requests. This includes the web pages that require frequent data updates or display dynamic content on every request. In such situations, server-side rendering is the better option. The process might be slower, but the pre-rendered web page will always display updated information. Although not recommended, you can skip the pre-rendering and leverage client-side JavaScript to frequently populate updated data. Server-side rendering In a static generation, the pre-render HTML is used with each request. But, in server-side rendering, the web pre-rendering method generates the HTML rather than reusing it on each request. Since no content is cached, server-side rendering is a slower process when compared to Static Site Generation. However, it is essential for web pages with dynamic content that changes frequently or with each request. The flexibility of server-side rendering makes it useful in many cases. This includes:

4. ● ● ● Responding to the most unexpected request a user makes. Extract the most updated content from the database rather than serving older static files. Selectively protect the content from unauthenticated uses or harmful websites requesting access. Server-side rendering is ideal for the following web pages: ● ● News update section where the content gets updated frequently. Parent web page of blog section that displays the list of most recent blogs. In previous times, static/server rendering during React-based websites was a challenging job. But things have significantly changed. With Prerender Nextjs Apps and tools, pre-rendering has become a much easier task to accomplish. Which one should you choose? The selection depends upon the type of web page or website you want to create. If displaying static content is possible for every request, static rendering is a better option since it will provide you with a faster, cost-effective, and simplest solution. However, under the following situations, server-side rendering is a better option: ● ● When it is not possible to predict all requests. If the page content or website response changes for different people viewing it / geographical locations. The responses quickly become out of date and need consistent updates. ● The classic examples of server-side-based pages include social networks or online marketplaces that require a frequent content updates and might change content depending on who is accessing it all and from where it is accessed. However, stellar improvements in static and server rendering tools have significantly closed the gap.
