What is Server-side Rendering?

Server-side rendering is an approach used to render web pages in the server instead of rendering it on client-side. It helps to load webpages quickly and improves performance. Typically, webpage content is rendered in the client-side using JavaScript. This approach requires more time to render webpages as JavaScript has to download and run before the browser can start rendering the page. Server-side rendering helps to render the content before the user can interact with the page.

Server-side rendering has several advantages in Angular2.x:

  • Improved Performance: Server-side rendering eliminates the need to download additional JavaScript code, enabling faster loading time. This makes the webpages more responsive and user-friendly.
  • Better Search Engine Optimization (SEO): With server-side rendering, webpages rank higher in search engine results. This increases visibility and organic traffic for websites.
  • Lower Data Consumption: Unlike client-side rendering, server-side rendering does not require additional JavaScript code thus reducing data consumption.
  • Better UI/UX: Server-side rendering enables content to be displayed on the spot, eliminating the ‘blank page’ issue. This enhances the user experience.

Server-side rendering in Angular2.x enables developers to create user-friendly, SEO-friendly and performant websites. It helps to significantly reduce the page loading time and simplifies the development process. By using embedded APIs, developers can easily maintain their webpages. Additionally, client-side rendering can be used as an alternative approach. This helps to reduce loading time and use resources more efficiently.

2. Unveiling the Steps of Server-side Rendering in Angular2.x

Identifying the Problem

For modern web applications, server-side rendering has become an increasingly important task. At its core, server-side rendering is the process of taking an application that is written in a client-side language like JavaScript and rendering it on the server in order to improve the user experience. Despite its significance, server-side rendering can be a difficult and complex problem to tackle. How can developers ensure that their Angular2.x application is responsive to different devices and users?

Understanding the Solution

When constructing an application that includes server-side rendering using Angular2.x, it is important to consider the layout of the application. While there are many ways to approach this task, a good practice is to create a single page application (SPA) shell. In a SPA, the application is divided into two parts. The first part is the server-side, which is responsible for building the application and rendering on the server. The second part is the client-side, which is responsible for running the application in a user’s browser. By implementing a SPA shell, developers can ensure that the application is responsive to different devices and users.
As part of the server-side rendering process, developers should also consider the caching of assets and data. When an application is rendered on the server, static assets such as JavaScript and CSS files must be cached in order to reduce the amount of time required for the application to render. Furthermore, data must be stored for future reference in order to ensure that the user experience remains consistent. This can be accomplished by using a caching layer such as Redis or Memcached.
Finally, developers must consider how to render their Angular2.x application quickly. In order to speed up the process of server-side rendering, developers should take advantage of server-side pre-rendering. By pre-rendering the application on the server, developers can significantly reduce the amount of time required to render the application for each user request. This can be achieved by using a library such as, which allows developers to pre-render their application on the server.
By considering the layout, caching of assets and data, and pre-rendering, developers can ensure that their Angular2.x application is responsive to different devices and users. But what other best practices should developers implement when it comes to server-side rendering for their Angular2.x application?

3. Optimizing the Performance with Server-side Rendering in Angular2.x

What Is Server-Side Rendering?

Server-side rendering (SSR) is a type of programming that is done on the server (not the client) in which an HTML page is generated dynamically and delivers it to the user. This means that when a user interacts with a website, the server will take into account the current page state and retrieve the appropriate HTML that corresponds with it. This is in contrast to the traditional approach of a client-side rendered application where the JavaScript code is sent to the user’s browser to construct the HTML page.

The Benefits of Server-Side Rendering

Using SSR over client-side rendering offers several advantages, particularly with respect to performance. By having the server deliver an HTML page, there is no need for users to wait for the JavaScript to be downloaded and executed by their browsers, which can result in faster user-experience. Additionally, server-side rendering can produce better SEO results than client-side rendered pages, since the pages are delivered as they are generated on the server.
Furthermore, SSR can enable more reliable caching than with client-side rendering. Caching can be performed on the server by having it generate the HTML page on a periodic basis, and then storing the HTML in a database for quick retrieval when needed. This allows the serving of the pages to be much more efficient since the server can take advantage of the existing cached HTML version when it needs to respond to user requests.
Another important advantage of server-side rendering is the improved security that it offers. With SSR, the server takes on the responsibility of delivering the HTML based on the current user input. This allows the server to handle potential security threats in a much more proactive way than with client-side rendering, which is more reliant on the client-side code.
Lastly, SSR can make the debugging process much simpler and more efficient. For example, when a client-side rendered website experiences an error, the entire page would need to be reloaded and debugging would need to be done on the client’s browser. With SSR, the server can quickly detect and fix the error on the server before sending the response back to the client.
Thought-provoking question – How can server-side rendering optimize performance in Angular2.x? The key idea is that SSR offers several advantages over client-side rendering when it comes to performance, SEO, caching, security, and debugging. It eliminates the need for users to wait for JavaScript to be downloaded and executed by their browser, enabling faster website response times. Additionally, it can result in better SEO performance, better cache control, and stronger overall security. Finally, it simplifies the debugging process, by allowing server-side detection and fixing of errors before they’re sent to the client.
When implementing SSR in Angular2.x, it is important to keep in mind the performances benefits that can be achieved. First, optimising the rendering of complex components should be done on the server, including avoiding unnecessary calls to API servers. Additionally, use caching efficiently so as not to overwhelm the server with requests. Finally, use virtual DOM libraries like React in order to improve the performance of dynamic parts of the page. These important best practices, when correctly implemented, can help to ensure maximum performance from server-side rendering.
