Angular Server Side Rendering – Angular Universal

A user can interact with Angular JS applications by rendering the pages when they are executed on the client browser. There are times when we must render the pages prior to build, for example, on the server. Angular Universal solves this problem.

The server-side execution of Angular Universal creates static pages that are then sent to the client browser to be displayed. The app is rendered more quickly and users are able to see the application’s layout through Angular Universal. Angular Universal is a powerful tool for implementing SSR. Let’s find out more about AngularJS development services & SSR.

Angular Universal Server-Side Rendering

After being introduced to client-side rendering, Angular developers have largely abandoned server-side rendering. So, what exactly is SSR? A server-side rendering (SSR) is when the server returns the static HTML page to the client, complete with all the data. Whenever a route is changed, the server must repeat the entire process. For retrieving dynamic data, a script is run on the server side.

Benefits of Server Side Rendering

  • By reducing the initial load time of a page, it improves user experience.
  • In addition to the application loading faster, the search engine bots will be able to crawl & index the pages more efficiently. Thus, gives a better SEO experience.
  • Upon copying and sending a page link, image, the page title, and description will appear, along with a pleasant preview. It helps in Social Media Optimization.
  • Optimal solution for users and Angular developers with slow internet connections.

Angular Universal: Overview

In the Angular Universal application, the static HTML page is rendered on the server and then returned to the client for display. Angular Universal is, in essence, Angular JS Server Side Rendering.

Angular Universal and Server-Side Rendering (SSR) Implementation

1.    Checking AngularJS Version

  • Use this command to determine the version of your Angular CLI: ng –version
  • Use ” npm i -g @angular/cli ” to upgrade your CLI if it’s less than version 9.

2.    Creating Angular JS App

  • Build an Angular SSR Demo using the command “ng new Angular-SSR-Demo”. In the Angular CLI, a folder is created and the appropriate packages and dependencies are installed.
  • Navigate to the project by typing “cd Angular-SSR-Demo”

3.    Running Angular App

  • Run your application on your local machine by entering the command “ng serve” in the terminal.

The application will run on http://localhost:4200.

  • To see the page source, right-click the browser and choose view page source from the menu. You’ll see a similar screen as shown below.

The only thing you are able to see here is * app-root > * / app-root >, and no static HTML page is displayed; that’s because most of the information is loaded at the client. Client-side rendering is the default setting for applications created through CLI. The Server-side Rendering (SSR) functionality of Angular Universal can make server-side rendering easier.

4.    Add Angular JS SSR to your App

  • Enter the following command to add SSR to your application: “ng add @nguniversal/express-engine”

In addition to creating new files, the command will update a few existing files.

Upon executing the command, you’ll see the following in your terminal:Adding Angular SSR to App

  • It can be seen that 4 new files have been created and 5 have been updated. Angular developers can check out the newly added scripts & packages in the package.json file.

5.    SSR Results

  • For a local look at the SSR results, we will run the application using the command “npm run dev : ssr”.

As we did not change the HTML, we will have the same UI.

  • Select your browser’s view page source option and click on it; now you will see your UI’s static HTML tags & styles in the page source. Please see the image below for an illustration.
