Description: Mutation logic refers to the rules and processes that govern how mutations are executed in GraphQL. In this context, a mutation is an operation that allows modifying data on the server, as opposed to queries that only retrieve information. Mutation logic establishes how these operations should be structured, what parameters are necessary, and how responses are managed. This includes data validation, access authorization, and error handling. Mutation logic is essential to ensure that write operations to the database are secure and efficient, allowing developers to clearly define how resources can be created, updated, or deleted. Additionally, mutation logic may include the implementation of transactions, ensuring that operations are performed atomically, meaning that all parts of the mutation succeed or none do. This is crucial in applications where data integrity is essential. In summary, mutation logic not only defines how write operations are performed in GraphQL but also establishes a framework for security and data integrity in web applications.
