How to Set a Dynamic Title for Specific Components in Angular

When developing applications using Angular, one common requirement is to display a title that represents the current state of the application or the specific user view. Dynamic titles are particularly important for enhancing user experience and improving Search Engine Optimization (SEO). In this guide, we will explore how to set a dynamic title for specific components, especially when dealing with routes.

The Problem: Static Titles in a Dynamic Application

In your Angular application, you may have various components corresponding to different routes, such as an index page, a blog, and a product page. For example, you might have the following routing setup:

In this case, the default title for the application can be set to "Shop". This is perfectly fine for the Index and Blog pages, but the Product page requires a title that is fetched from the server, based on the specific product being viewed (like "iPhone 7", "iPhone 8", "Skirt", etc.).

So, how do we achieve this exciting functionality of setting a dynamic title based on the route?

The Solution: Using Angular's Title Service

Angular provides a convenient service called Title, which is part of @ angular/platform-browser. This service allows you to set the title of the document dynamically. Here’s how you can do it in a step-by-step manner.

Step 1: Import the Title Service

Firstly, you need to import the Title service in your component:

Step 2: Inject the Title Service

Next, you can inject the Title service into your constructor. This will allow you to utilize its methods to set the title dynamically. Here's an example of how it can be done in a product component:

In the code snippet above, you set the title to "Shop", but ideally, you would want to replace it with the actual product name fetched from the server.

Step 3: Setting the Title Based on Route Changes

To make your application even more dynamic, you can listen to route changes and update the title accordingly. Let's say you want to update the title in the AppComponent based on the current route:

Explanation of the Code

Injection: Both Title and Router services are injected into the component.

Subscription: The router events are subscribed to listen for NavigationEnd, which indicates that navigation has finished.

Conditional Title Setting: Depending on the current route, you can set different titles:

For the Product page, fetch the specific name and set it, if available.

For other routes like Index and Blog, a default or a dynamic title string can be set.

Conclusion

By employing the Title service, you can effectively create a dynamic title system that responds to different components and user routes in your Angular application. Not only does this technique enhance user experience by providing relevant information, but it also plays an essential role in SEO by ensuring that search engines can accurately index your pages.
