Purpose of ActivatedRoute

The main purposes of the ActivatedRoute service include:

• Accessing Route Parameters: Route parameters are dynamic values that are part of the URL path. For example, in the URL /users/:id, id is a route parameter. The ActivatedRoute allows components to access these parameters, enabling dynamic content based on the route.
• Accessing Query Parameters: Query parameters are key-value pairs appended to the URL after a question mark (?). For instance, in the URL /search?q=angular, q is a query parameter. With ActivatedRoute, components can retrieve and utilize query parameters for various purposes, such as filtering data or customizing views.
• Accessing Route Data: Angular’s router allows to attach additional data to route configurations. This data can include metadata about the route or any other information needed by the associated component. The ActivatedRoute service provides access to this data, enabling components to retrieve and utilize it as required.
• Observing Route Changes: Angular applications are dynamic, and routes can change based on user interactions or application state. The ActivatedRoute service provides observables that emit events whenever route parameters, query parameters, or route data change. Components can subscribe to these observables to reactively update their state or behavior based on route changes.
• Accessing the URL: In addition to route-specific information, the ActivatedRoute service also provides access to the URL associated with the current route. This can be useful for components that need to inspect or manipulate the URL programmatically, such as implementing navigation logic or generating dynamic links.

In Angular applications, navigation is a fundamental feature, that helps to move between different views and components easily. The ActivatedRoute service plays an important role in this navigation process, providing valuable information about the current route, including route parameters, query parameters, and other route-specific metadata. In this article, we’ll learn more about the ActivatedRoute in detail.
