What are Angular resolvers and how do they work?

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

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.

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 resolvers only used for data fetching?

Primarily, yes. However, they can also be used for other pre-processing tasks before a route is activated.
