Server-Side Rendering with Angular


In recent years, web development has seen a shift towards creating dynamic and interactive Single Page Applications (SPAs) using frontend frameworks like Angular. While SPAs provide a smooth user experience, they have certain limitations when it comes to search engine optimization (SEO) and initial load times. This is where Server-Side Rendering (SSR) comes into play. In this blog, we will explore what SSR is and how to implement it with Angular to improve performance and SEO for your web application.

What is Server-Side Rendering (SSR)?

It is a technique used to render web pages on the server side before they are sent to the client’s browser. Unlike traditional Single Page Applications, where the initial page loads as an empty shell and is then populated with data and content using JavaScript, SSR delivers fully-rendered HTML to the browser, improving the time to first meaningful paint and enhancing SEO.

Benefits of Server-Side Rendering with Angular

1. Improved Initial Load Time

By rendering the page on the server-side, SSR reduces the initial load time, especially on slower internet connections and less powerful devices. Users can see content faster, leading to a better user experience.

2. SEO Optimization

Search engines rely on crawling the HTML content of your pages. With SSR, your Angular application’s content is readily available in HTML, making it easier for search engines to index and rank your pages, ultimately improving your website’s visibility in search results.

3. Better Accessibility

Some web crawlers and bots may have limited or no support for JavaScript. By using SSR, you ensure that all users, regardless of their browsing capabilities, can access your website’s content.

4. Social Media Sharing

When sharing links on social media platforms, the content is usually scraped from the HTML of the page. This ensures that the correct content is displayed when users share your links on social media, resulting in better previews and engagement.

Implementing Server-Side Rendering with Angular

To implement SSR with Angular, follow these steps:

1: Create a new Angular project or use an existing one.

ng new my-ssr-app

2: Install Angular Universal, which provides SSR capabilities for Angular applications.

ng add @nguniversal/express-engine

3: Build the application for SSR.

npm run build:ssr

4: Test the application in SSR mode.

npm run serve:ssr

5: Update your server to handle SSR requests. Angular Universal uses Node.js as the backend server for SSR.


Server-Side Rendering is a powerful technique that enhances web application performance and search engine visibility. By implementing SSR with Angular using Angular Universal, you can ensure that your application delivers fast and fully-rendered content to users and search engines. This not only improves the user experience but also positively impacts your website’s SEO rankings and accessibility. Happy coding!
