Definitions of Server-side Rendering in Angular

Server-side rendering is a specific type of rendering which is used to provide a dynamic web page to the user in response to a request. It uses the computing power of the server to render and generate the needed web page. In the case of Angular, server-side rendering consists of rendering the initial state of an application on the servers, instead of in the browser. This way, the initial rendering of the page will be done much faster, and the end-user will see the page as soon as the application is loaded in the browser.
Server-side Rendering is the method of rendering a web page on the server-side before it is sent to the browser. In such a case, the server does the processing required to create a web page and sends the rendered HTML output back to the browser.
Angular is an open-source web framework for building user interfaces and single-page applications (SPAs) from the Angular team at Google. The framework consists of a combination of HTML, CSS, and JavaScript, that allow developers to create dynamic UIs with components and data binding.
Dynamic Requests are requests that need to be processed immediately as opposed to being cached or stored for future use. Such requests include applications built with Angular as they must be rendered in response to the user’s request.
Application Initial State refers to the state of the application when it is first launched. By pre-rendering the initial state of an application, user experience is improved significantly as the page is loaded faster than when rendering in the browser.
Server-side rendering in Angular is an important part of creating dynamic user interfaces and applications. It allows for improved performance and a faster loading of UIs by pre-rendering the initial state of the application on the server. By using the server’s computing power, this method of rendering can save valuable time and resources for developers and users alike.

1. Definition of Server-Side Rendering in Angular

Server-side rendering (SSR) in Angular is a process for rendering HTML pages on the server side rather than on browsers. This process is often used by developers to improve the overall performance and speed of their web applications.

What is Server-Side Rendering?

Server-side rendering is a form of deferred rendering. A deferred renderer executes slowly with the result that the initial page is displayed faster. Instead of executing all the code in the web server’s memory, requests for server-side rendering allows a request to be sent to a web service, which returns the HTML page rather than executing it first. The benefit of this is that if there are many requests for the webpage, the web server can serve multiple requests at once, reducing the loading time of the webpage.

What are the Benefits of Server-Side Rendering?

Server-side rendering of a web page is a beneficial process for many websites, particularly for websites that experiences constant and heavy traffic. Although some may feel that deferred rendering of a page or web application can negatively affect user experience, it is the quick, efficient, and secure nature of the process that has allowed it to become a popular choice. The following are some of the main advantages of server-side rendering:

  • Faster initial load time
  • Reduces the entire processing and loading time of the web application
  • Decreases server load as more requests can be handled with less CPU resources.
  • Improves overall security of the web application.

Server-side rendering is a process that relies on the efficient and organized coordination of the web server and the code that runs the web application. For this reason, developers should always ensure that their applications are enabling the smooth coordination between the server and the code. This can be achieved by using asynchronous techniques, such as streaming, for loading data from the server. Furthermore, the organization of files and resources handling should be efficient to ensure fast loading times.

2. Advantages of Using Server-Side Rendering in Angular

Server-side rendering (SSR) is the process of taking an Angular application and rendering it in a server-rendered environment, before it is sent to a client. SSR offers several advantages over client-side rendering, including improved performance and faster loading times.

Performance Benefits

One of the main advantages of server-side rendering is improved performance. By transferring the computational workload of the application to the server, the user experience can be significantly enhanced. Server-side rendering also reduces the cost of rendering HTML on the client side, as the server can render the page without needing to wait for the client to download and parse the Javascript code. Additionally, since the application is already pre-rendered on the server, it eliminates the need for the client to download and execute the same code, further improving performance.


Another great advantage of server-side rendering is that it makes applications more SEO-friendly. Without SSR, search engine crawlers are unable to render the application correctly and are only able to access the raw HTML generated from the Javascript. This makes it difficult for crawlers to interpret the content, resulting in a poor ranking for the application in search engine results pages. However, when an application is server-side rendered, the crawlers are able to read the content much more easily, resulting in an improved ranking.
Finally, SSR can also help to improve the overall user experience, as applications rendered on the server side can be seen by users much faster than applications that are client-side rendered. Server-side applications are also more secure since all the code is executed on a secure server, rather than on the user’s device. As a result, applications rendered on the server side are less likely to be exposed to potential security vulnerabilities.

3. Challenges of Using Server-Side Rendering in Angular

Server-side rendering (SSR) is a popular way to render content in modern web development, and Angular is one of the leading frameworks for server-side rendering. The advantages of Angular for server-side rendering are clear, with improved website performance, better SEO, and the ability to deliver the same content to multiple platforms. However, there are some key challenges for developers when it comes to using server-side rendering in Angular.


One of the biggest issues facing developers using server-side rendering in Angular is the performance of their applications. Because server-side rendering requires a bulk of the processing to occur server-side, the rendered page may take longer than usual for the user to see in their browser. Furthermore, some complex operations such as retrieval of large data or integration with APIs may need to be done faster or more efficiently due to the limited resources available in a server-side rendered environment.

Merging Content with Client-Side Rendering

Another challenge of server-side rendering with Angular is merging server-side rendererd content with client-side rendering. In order to present a unified experience, the content produced by server-side rendering must accessible to the application for use in client-side rendering. This can be done by loading the server-rendered content into the Angular application’s variables or other in-memory storage, and having the application render this content alongside the server-rendered content. While this can be accomplished, the extent of the solutionrequired varies greatly from case to case. Not to mention, it increases the complexity of the final application code.
The many advantages of using server-side rendering in Angular should certainly not be overlooked, however, developers should also be aware of the potential challenges in order to best utilize the technology and create an optimal user experience. Good planning and thorough testing are key in ensuring the success of any server-side rendering project.


What is the impact of server-side rendering on user experience and performance?
Server-side rendering allows applications to significantly improve user experience and performance. By pre-rendering the content on the server, the client’s browsers can rapidly load the page, improving overall user experience. Also, by not having the client to execute the code on the client’s browser, performance is also improved. However, the implementation of server-side rendering requires additional overhead, such as backend support, for the server to generate the content. Therefore, there is a tradeoff between faster loading speeds and higher initial setup cost when implementing server-side rendering.
Are you interested in creating the best user experience possible? If so, keep an eye out for new developments in server-side rendering and the ways which it further revolutionizes user experience and performance. Be sure to stay tuned for future releases, so that you can keep using the latest cutting-edge technology.
