What are Angular Router Resolvers and how do they work?

Angular Router Resolvers are services that allow you to pre-fetch data before navigating to a route. They ensure that the required data is available when the component is loaded.

Can you give me an example of how to implement a resolver?

Sure! You can create a resolver by implementing the Resolve interface and defining the resolve method to fetch data. Then, you can add it to your route configuration.

What happens if the resolver fails to fetch data?

If a resolver fails, the navigation to that route will be canceled, and you can handle the error by redirecting to an error page or showing a message.

Are there any best practices for using resolvers?

Yes, it's best to keep resolvers lightweight, avoid complex logic, and handle errors gracefully to enhance user experience.
