Understanding Angular ActivatedRoute Service to Access Route Parameters, Query Params, and Route Data Easily

 Description:

In Angular applications, routing is a powerful feature that allows seamless navigation between components. But to make the most of it—especially when dealing with dynamic URLs, passing data, or filtering content—you’ll need the ActivatedRoute service. This built-in Angular service gives you access to route-related information such as route parameters, query parameters, and static route data.

Whether you’re building a user profile page based on ID (/users/:id) or filtering blog posts with query parameters like ?category=tech, ActivatedRoute lets you access all this information inside your component.

You can use it to:

  • Read dynamic route parameters (e.g., user ID)

  • Get query parameters (e.g., search filters)

  • Access custom static data defined in your route config

  • React to param or query changes using Observable

Quick Summary:
