Angular Universal executes on the server-side by generating static pages and later are sent to the shopper browser for show. Thus, Angular Universal renders the app a lot more quickly and permits users to look at the application’s layout. While not any ruckus, let’s learn a lot concerning SSR with Angular Universal.

What is Server-Side Rendering?

Server-Side Rendering was enforced a few years past, however we’ve got lessened the utilization of SSR when being introduced to client-side rendering. So, let’s see what SSR is?

Server-Side Rendering (SSR) means that the server can come the static hypertext mark-up language page, together with all the information, to the shopper, when aggregating everything. The server needs to perform the whole method once more whenever the route changes. The server-Side script is employed to fetch the dynamic data; these scripts are written within the server-side language.

Let’s discuss a number of the benefits of SSR.

Advantages of SSR

What is Angular Universal?

Angular Universal is the method that manages to render the static hypertext mark-up language page on the server and any come to the client-side. In a very shell, Angular Universal is Angular Server aspect rendering.

Steps to implement Server-Side Rendering (SSR) with Angular Universal

Step – 1 Angular Version Checking

• Check the version of your angular interface victimization this command

ng –version

• If your interface version is a smaller amount than v9, then upgrade to the most recent version victimization this command

npm i -g @angular/cli

Step – 2 a pair of produce Angular Application

• Create Angular Application victimization this command

ng new Angular-SSR-Demo

Angular interface can produce a folder and install the desired packages & dependencies.

• Navigate and open the project

cd Angular-SSR-Demo

Step – 3 Run Angular Application

• Open the terminal and enter the command to run your application on your native machine.

ng serve

Your application is running on http://localhost:4200.

• Right-click on the browser and click on the read page supply; the page source is almost like the given image below.

Here you’ll solely see < app-root > < / app-root >, and no static hypertext mark-up language page is displayed; it’s a result of most of the information being loaded at the client-side. By default, the appliance created with the interface is organized to own client-side rendering. Whereas with the assistance of Angular Universal, we will assemble server-side rendering (SSR) swimmingly.

Step – 4 Adding Angular SSR to our Application

• For adding SSR to your application, enter the subsequent command

ng add @nguniversal/express-engine

The command can produce a few files & will update some existing files.

After the command is dead, you’ll see one thing like this in your terminal-

• You will see that four new files are created & five files are updated. Let’s have a glance over the changes within the package.json file to look at recently more scripts & packages.

Step – 5 results of SSR

• To see the results of the SSR on a neighborhood machine, we’ll currently get to run our application victimization this command

npm run dev : ssr

The UI can stay identical, as we tend to haven’t modified the hypertext mark-up language.

• Right-click on the browser and click on on the read page source; currently, the page supply can show the static hypertext mark-up language tags & designs for our UI. It’ll be one thing just like the below-given image.

Conclusion

So, this was all concerning Server-side rendering with Angular Universal. I hope your purpose of landing on this Angular universal tutorial is served. Angular developers at Bacancy Technology are enthusiastic and might fulfill your complicated product needs by setting-up server-side rendering and pre-rendering with Angular Universal and specific.
