Description: In the context of GraphQL, ‘Field Resolver’ refers to the functions that determine how the fields of a query are populated. Each field in a GraphQL query can have an associated resolver, which is responsible for providing the data for that specific field. Resolvers are functions that take as input the query arguments, the context, and information about the parent object, and return the result that should be sent to the client. This architecture allows for great flexibility and customization in how data is retrieved and structured, as resolvers can interact with databases, external services, or any other data source. Additionally, resolvers can include additional logic, such as data manipulation or authorization, making them an essential part of implementing a GraphQL API. In summary, field resolvers are fundamental to the functioning of GraphQL, as they allow queries to be dynamic and adaptable to the specific needs of clients.
