Angular Routing Interview Questions
Angular routing interview questions often focus on understanding how routing works in an Angular application, including route parameters, nested routes, lazy loading, route guards, and resolving data before routing. Interviewers may also ask about the differences between hash-based and HTML5 routing strategies in Angular, as well as how to configure and implement routing in an Angular project using the Router module. Additionally, questions may explore how to handle route not found scenarios, route redirects, and best practices for organizing and managing routes in large Angular applications. It is important for candidates to have a solid understanding of Angular routing concepts and practical experience working with routing in Angular projects to excel in interviews.

1 - What is Angular routing and why is it used?
Angular routing is a functionality that allows navigation between different components of an Angular application without reloading the entire page. It helps in creating a single page application experience by dynamically loading content based on the URL.
2) How do you define routes in an Angular application?
Routes in Angular are defined using the Angular Router module. We set up routes in the app routing.module.ts file using the RouterModule.forRoot() method to define the routes and their corresponding components.
3) Can you explain the concept of route parameters in Angular routing?
Route parameters allow passing data via the URL to a specific component. These parameters are defined in the route path with a colon followed by the parameter name, which can then be retrieved using the ActivatedRoute service.
4) How can you implement lazy loading of modules using Angular routing?
Lazy loading improves performance by loading modules only when they are required. To implement lazy loading, we define a separate module for the feature module and load it asynchronously using the loadChildren property in the route configuration.
5) What is the purpose of canActivate and canDeactivate guards in Angular routing?
CanActivate guard is used to control access to a particular route based on certain conditions, such as authentication. On the other hand, CanDeactivate guard is used to prevent navigation away from a route based on unsaved changes or data in a form.
6) How can you handle routing errors in an Angular application?
To handle routing errors in Angular, we can define a wildcard route ‘**’ that acts as a catch all route for any invalid URL. We can then redirect the user to a default route or show a custom error page.
7) Explain the role of RouterOutlet in Angular routing.
RouterOutlet is a directive provided by the Angular Router module that acts as a placeholder where the routed component is displayed. It dynamically renders the component based on the matching route configuration.
