How to Open Product Details on a New Page in Angular: A Simple Guide

Creating an engaging e-commerce website involves much more than displaying a list of products. As a beginner in Angular, you may have successfully set up your homepage showing product titles and prices. However, to enhance user experience, you need to provide a way to show detailed information about each product on a new page. In this guide, we'll explore how to achieve this by using Angular's routing system effectively.

The Problem

You have a list of products fetched from an API, displaying elements like the product title and price. Each product also includes a wealth of additional data that you want to show when the user clicks on a product. The question is: how do you open a new page that displays all the details about a product when it is clicked, and how do you fetch all this data?

The Solution

To solve this problem, you'll follow a few structured steps:

Step 1: Setting Up Routing

You already have a routing configuration, but let's ensure it's correctly set up to handle displaying individual product details. You have defined a route like this:

Step 2: Creating a Service Method

To show the detailed information of a product when a user clicks on it, you need to retrieve the product data again using its ID. It is important to make a new API call to fetch the product details rather than passing the entire product object.

Update your service with a new method:

Step 3: Fetching Product Details in the Component

Next, within your ItemComponent, you need to retrieve the ID from the URL, then make a call to your newly created method to fetch the product details.

Implement the logic in your component:

Step 4: Displaying the Product Data

Once you receive the product details, you can then display these details in the template of your ItemComponent. This might involve binding the data to your HTML elements.

Recap

With these steps, you should now be able to:

Set up Angular routing for your product items.

Make a new API call to fetch product data when navigating to the details page.

Display the product details effectively.

By following this guide, you can create an intuitive e-commerce site that provides users with rich product information, enhancing their shopping experience.

Conclusion

Opening product details on a separate page in Angular takes advantage of the framework's routing capabilities and service methods to fetch data efficiently. By structuring your solution in clear steps, even beginners can create robust functionality for their applications. Happy coding!
