What are Angular route resolvers and how do they work?

Angular route resolvers are services that pre-fetch data before a route is activated. They ensure that the necessary data is available for the component before it loads.

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

Sure! You can create a resolver by implementing the Resolve interface and defining a resolve method that fetches the data.

What happens if the resolver fails to fetch data?

If a resolver fails, the route will not activate, and you can handle the error by redirecting to an error page or showing a message.

Are there any best practices for using route resolvers?

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