The Scenario

You are a frontend engineer at an e-commerce company. You are building a new public-facing website that needs to be fast and SEO-friendly.

You are considering using server-side rendering (SSR) to improve the performance and SEO of the website.

The Challenge

Explain what server-side rendering (SSR) is in Angular and how you would use it to solve this problem. What are the key benefits of using SSR?

Wrong Approach

A junior engineer might not be aware of SSR. They might try to solve this problem by pre-rendering the pages, which would not be a very scalable solution.

Right Approach

A senior engineer would know that SSR is the perfect tool for this job. They would be able to explain what SSR is and how to use it to improve the performance and SEO of a website. They would also be aware of Angular Universal, which is the official way to do SSR with Angular.

Step 1: Understand What SSR Is

Server-side rendering (SSR) is the process of rendering a single-page application (SPA) on the server and then sending the fully rendered page to the client.

Step 2: The Benefits of Using SSR

Step 3: How to Do SSR with Angular Universal

Angular Universal is the official way to do SSR with Angular. Here’s how you can add it to your existing Angular application:

ng add @nguniversal/express-engine

This command will automatically add the necessary files and configurations to your project.

Step 4: Build and Run the Application

Once you have added Angular Universal to your project, you can build and run the application with the following commands:

npm run build:ssr
npm run serve:ssr

This will start a Node.js Express server that will render your application on the server.
