Description: A mutation definition describes the structure and behavior of a mutation in GraphQL. In this context, a mutation is an operation that allows modifying data on a server. Unlike queries, which are used to retrieve information, mutations are designed to create, update, or delete records. Each mutation has a name and can accept arguments that specify the data to be modified. Additionally, mutations can return a result, which typically includes the updated data or a confirmation message. Mutations are fundamental for interacting with GraphQL APIs, as they enable developers to efficiently and consistently manage the application’s state. The structure of a mutation resembles that of a query but is defined within a specific block that indicates its changing nature. This provides clarity and organization in the API definition, making it easier for developers to use and understand. In summary, mutations are an essential part of GraphQL that allow structured and efficient data manipulation, making them a powerful tool for modern application development.
