Should I use SSR?
If you are a Developer, concerned about Users' Internet speed, you should use SSR for a fast data transmission. SSR is vital to serve fast experience for users who have a low speed Internet connection. If your site is Heavy and serve to Thousands of users, you can skip using SSR for improved performance.
Do you always need SSR? The short answer would be no. Not all apps need server-side rendering, especially apps with a dashboard and authentication that will not need SEO or sharing via social media. Plus, the expertise for building a server-rendered React app is higher than an app initialized using create-react-app.
One of the main arguments for why (though CSR is making significant strides in that direction which we'll explore in more detail later), is that SSR has traditionally been the better choice in the context of search engine optimisation (SEO) because SSR pages are more accessible to search engine bots and crawlers.
SSR is used to fetch data and pre-populate a page with custom content, leveraging the server's reliable internet connection. That is, the server's own internet connection is better than that of a user with lie-fi), so it's able to prefetch and amalgamate data before delivering it to the user.
Between the two options, server-side rendering is better for SEO than client-side rendering. This is because server-side rendering can speed up page load times, which not only improves the user experience, but can help your site rank better in Google search results.
Pros of SSG:
your page is much faster than a server-side rendered one because the entire logic was executed at build time. your backend serves only static files, which contributes to decreasing the server load, you can run your statically generated page in the preview mode; the page is then rendered at request time.
Disadvantages of SSR
🍔SSR can improve performance if your application is small, but it can also degrade performance if it is heavy. ⌛Increased time can be even worse if the server is busy.
Vulnerability: SSR sites are harder to keep secure because they have a bigger surface to attack than CSR sites. This is however not an issue if you or your developers know what they're doing. Complex caching: configuring your cache is usually more complex on SSR sites than CSR sites.
The initial page load time in SSR is faster than CSR. When compared, SSR loads 1-1.5 seconds faster than CSR. This is because, in SSR, the server responds by sending pre-rendered HTML, which can be viewed by the user.
Yes, Facebook uses SSR heavily. However, according to Lee, there are very few areas where they use React to render components on server. This was primarily a decision based on their server environment which is Hack.
Is SSR faster than spa?
In general, SSG sites and SSR sites are faster than SPAs in terms of loading content. SPAs, as mentioned earlier, need to download the JavaScript for the app before they can display content. However, in some cases, SSG and SSR can be slower.
Server-side rendering improves site speed and results in better Core Web Vitals scores. However, sometimes it can be difficult to implement and might also increase First Input Delay.
I found that server side rendering requires lots of CPU/mem resources and it greatly slows down my server. Even on a simple page it will have to process complex react, redux logic that involves store initialization, virtual dom, css extraction for every request.
A server is generally going to be orders of magnitude more powerful than a client machine; and managed code is generally much faster than scripting. However - the client machine also usually has a lot of spare computational power that isn't being used, while the server could be running requests for thousands of users.
Google has said in the past that they are able to crawl and index pages that use client-side rendering. But it needs to be implemented in a particular way so that the crawler can read the links and content on the pages.
Remember, we learned that Next. js does static site generation by default. It simply works out of the box. However, it will try to detect which pre-rendering method you're using for each page.
Next Js is a React-based framework that provides a developer with everything required for a production-grade application. SSR or Server Side Rendering is also known as dynamic rendering. In SSR the page is generated each time the server gets a request.
Server-side Rendering (SSR) is one of Gatsby's rendering options and allows you to pre-render a page with data that is fetched when a user visits the page.
js (SSR) vs. Create React App (CSR) Exploring the performance differences between server-side-rendering (SSR) and client-side-rendering (CSR) through simple examples.
In a nutshell, Next. js offers various tools and features to minimize the development process, whereas, React. js has better resources for the front-end development of your mobile and web application.
Can a SPA be SSR?
Intro to SSR
In a single page application, the server only generates the very first page that the user requests, leaving all subsequent pages to be rendered by the browser. To accomplish server-side rendering of an SPA, javascript code is executed in NodeJS to generate the initial HTML.
While SPAs load all of their data on a single HTML site that is rendered only after a client request, static site generators take a very different approach to content and to building pages in general. Static Site Generators generate content at the build time of new pages or when changes are made to the content.
SPAs are not inherently friendly to search engines—but don't take our word for it. According to SEO expert Barry Adams, React-based SPAs (and other JavaScript-based SPAs), don't play nicely with Google's crawler.
With client-side rendering, the initial page load is going to be slow. Because communicating over the network is slow, and it takes two round trips to the server before you can start displaying content to the user. However, after that, every subsequent page load will be blazingly fast.
js is one of the most popular frameworks to set up SSR for a React application and Express is a great option for creating the HTTP server.
Server-side rendering (SSR), is the ability of an application to contribute by displaying the web-page on the server instead of rendering it in the browser. Server-side sends a fully rendered page to the client; the client's JavaScript bundle takes over and allows the SPA framework to operate.
Server-side rendering (SSR) is a popular technique for rendering a client-side single page application (SPA) on the server and then sending a fully rendered page to the client. This allows for dynamic components to be served as static HTML markup.
React along with other framework like angular and vue. js are traditional client side framework ,they run in browser but there are technology to run this framework on server side, and next. js is a solution for running react application server side.It also makes react development very simple.
Use Server-Side Rendering: Next. js pre-renders a page on each request. It will be slower because the page cannot be cached by a CDN, but the pre-rendered page will always be up-to-date.
If you are calculating something like age, you can do it in the client side, but if you are calculating something like currency, you should do it in server side with a BigDecimal because of it's precision.
Is WordPress a SSR?
PHP and MySQL are always server-side. For WordPress sites, server-side means: “Happening during the internal processing a server performs as it tries to serve a page back to a client who's requested it.” As a rule of thumb, PHP and MySQL are always server-side—they only run in a server environment.
React helps build a very user-friendly UI that is also valuable by SEO, so you definitely shouldn't avoid it while creating a user interface for your app/website. However, you should use some tricks to ensure that your React-site is understandable for Google crawlers and, therefore, good for SEO.
Whether you're building or consuming web components in your pages and apps, the way the components are built can really impact SEO. Google and Ask.com are the only two crawlers that are currently executing JavaScript. All of the rest are just looking at the markup when the page loads.
While Google examines the keyword context as well as the keywords themselves, Bing focuses more on the precise keyword(s). The next thing to consider is the impact of multimedia. Bing rewards websites using multimedia, such as videos and photos, more than Google does.
js (SSR) vs. Create React App (CSR) Exploring the performance differences between server-side-rendering (SSR) and client-side-rendering (CSR) through simple examples.
In the case of CSR, the HTML is generated on the client side by executing Javascript code in the browser. The Javascript code is executed by the browser Javascript engine (eg. Chrome V8, Nitro, SpiderMonkey etc.) In the case of SSR, the HTML is generated by executing code on the server-side.
In a nutshell, Next. js offers various tools and features to minimize the development process, whereas, React. js has better resources for the front-end development of your mobile and web application.
With client-side rendering, the initial page load is naturally a bit slow. However, after that, every subsequent page load is very fast. In this approach, communication with server happens only for getting the run-time data. Moreover, there is no need to reload the entire UI after every call to the server.
