Relay Query

A Relay Query is a way to request specific data from a GraphQL server using Facebook's Relay framework. It allows a client application to ask for exactly the data it needs—such as user details or posts—by specifying fields in a structured query. Relay manages these requests efficiently, enabling features like real-time updates and caching. Essentially, it streamlines communication between the app and server, reducing unnecessary data transfer and improving performance, making data fetching more predictable and maintainable in complex web applications.
