Description: A mutation resolver is a function that processes a mutation request and returns the result. In the context of GraphQL, mutations are operations that allow modifying data on the server, as opposed to queries that only retrieve information. Mutation resolvers are essential for implementing the business logic behind these operations, as they are responsible for receiving the necessary arguments, interacting with the database or any other data source, and returning the corresponding result. These resolvers can include validations, error handling, and the execution of asynchronous operations, making them key components for ensuring data integrity and consistency. Additionally, mutation resolvers can be used to create, update, or delete records, allowing developers to build interactive and dynamic applications that respond to user actions. In summary, mutation resolvers are a fundamental part of the GraphQL architecture, facilitating efficient and structured data manipulation.
