Description: Error handling in GraphQL refers to the strategies and practices implemented to manage and communicate errors that may arise during query and mutation operations. Unlike traditional REST APIs, where errors are typically handled through HTTP status codes, GraphQL adopts a more structured approach. In this context, errors are returned as part of the response, in a specific field called ‘errors’, allowing developers to obtain detailed information about what went wrong. This approach not only enhances the developer experience by providing clear and specific error messages but also enables better error management on the client side, facilitating the implementation of retry logic or exception handling. Additionally, error handling in GraphQL can include categorizing errors, differentiating between validation errors, authorization errors, and execution errors, allowing for a more appropriate response to each situation. In summary, error handling in GraphQL is essential for building robust and reliable applications, ensuring that developers can diagnose and resolve issues efficiently.
