If you are an Angular developer, you know how important it is to create fast and scalable web applications. One way to achieve this is by implementing Angular Universal into your existing Angular application. This article will explain what Angular Universal is, its benefits, and how to implement it into your existing Angular application.
With Angular Universal, the initial HTML payload has all the necessary content to make the application visible to the user, which significantly improves the load time of the webpage. This feature is particularly important for search engine optimization (SEO) because search engines prefer fast-loading pages.
Angular Universal also provides better performance on low-network connections, which is essential for users who are browsing the web from mobile devices or in areas with poor internet connectivity.
Angular Universal offers several benefits, including:
To implement Angular Universal, you need to have the following:
npm install -g @angular/cliin your command prompt.
ng add @nguniversal/express-engine.
Implementing Angular Universal in your existing Angular application is not difficult. You can follow these steps:
If you don’t already have an Angular application, you need to create one. You can create an Angular application by running
ng new my-app in your command prompt. This command will generate a new Angular application with a default configuration.
After you have created an Angular application, you need to add the Angular Universal package to it. You can do this by running
ng add @nguniversal/express-engine in your command prompt. This command will add the Angular Universal package and its dependencies to your existing Angular application.
After you have added the Angular Universal package to your application, you need to generate the server files. You can do this by running
ng generate universal my-app in your command prompt. This command will generate the necessary files for Angular Universal.
Once you have generated the server files, you need to build your application. You can do this by running
npm run build:ssr in your command prompt. This command will build your application with Angular Universal.
After you have built your application with Angular Universal, you need to serve it. You can do this by running
npm run serve:ssr in your command prompt. This command will start your application on the server side.
In conclusion, implementing Angular Universal in your existing Angular application can greatly improve its performance by rendering the content on the server-side, resulting in faster load times, better SEO, and an improved user experience.
With Angular Universal, you can take advantage of server-side rendering and provide a better user experience to your users. Follow the steps above, and you will be on your way to implementing Angular Universal in your existing Angular application.
