Description: Mutation validation in GraphQL is a crucial process that ensures that the input data for a mutation meets the required criteria before being processed. In the context of GraphQL, a mutation is an operation that allows modifying data on the server, such as creating, updating, or deleting records. Mutation validation is responsible for verifying that the data provided by the client is valid and in the correct format, which helps prevent errors and maintain database integrity. This process includes checking data types, verifying required fields, validating unique values, and applying specific business rules. Validation not only enhances application security by preventing the injection of malicious data but also provides a better user experience by offering immediate feedback on errors in the entered data. In summary, mutation validation is an essential component in the development of GraphQL APIs, ensuring that data modification operations are performed safely and efficiently.
