What is lazy loading in GraphQL and how does it work?

Lazy loading in GraphQL is a design pattern that delays the loading of data until it's actually needed. This can improve performance by reducing the initial load time.

Can you give me an example of how to implement lazy loading in a GraphQL query?

Sure! You can use the @defer directive in your GraphQL query to specify which fields should be loaded lazily. For example: query { user { id name posts @defer { title content } } }.

What are the benefits of using lazy loading?

The main benefits include improved performance, reduced bandwidth usage, and a better user experience, as users can interact with the initial data while additional data loads in the background.

Are there any downsides to lazy loading?

Yes, potential downsides include increased complexity in your code and the possibility of loading data too late, which can lead to a poor user experience if not managed properly.
