routeChangeSuccess

routeChangeSuccess is an event broadcast by Angular's $route service. This event fires after a route change has successfully completed and the new controller has been instantiated and linked to the scope. It is typically used to perform actions that should occur after the view has been updated and the associated controller has been executed.

The $routeChangeSuccess event passes two arguments to its handler: the new route's scope and the previous route's scope. The new scope contains all the data and methods associated with the currently active route, while the previous scope provides access to the scope of the route that was just navigated away from. Developers often use this event to update the document title, trigger analytics events, or perform any other side effects that depend on the current route's parameters or data.

It's important to note that $routeChangeSuccess fires after the DOM has been updated and the controller has been linked. If you need to perform actions before the route change is finalized, you should consider using the $routeChangeStart event instead. This distinction allows for different types of asynchronous operations or conditional logic to be implemented based on the stage of the routing process. Understanding the timing of these events is crucial for effective navigation and state management in Angular applications.
