Description: A schema resolver is a function that resolves the value of a field in a GraphQL schema. In the context of GraphQL, a schema defines the structure of the data that can be queried, including data types, relationships, and available operations. Resolvers are fundamental to the implementation of GraphQL, as they are responsible for providing the data requested by the client. Each field in a schema can have an associated resolver, which can be a simple function or include more complex logic that interacts with databases, external services, or any other data source. Resolvers allow GraphQL to be flexible and efficient, as they can be customized to meet the specific needs of various applications. Additionally, they can handle authorization logic and data validation, ensuring that only appropriate data is returned. In summary, resolvers are the bridge between the GraphQL schema and actual data, allowing queries to be executed effectively and giving developers full control over how data is retrieved and processed.
