Error handling is a critical aspect of building robust and reliable GraphQL APIs. As developers, we need to ensure that error responses are informative, consistent, and easy to handle on the client side.
In this article, we will explore advanced error-handling techniques in GraphQL. By leveraging these techniques, you can enhance user experience, provide meaningful error messages, and improve debugging.
We will use GraphQLError class of GraphQL to play with errors.
By customizing error messages, implementing validation rules, and centralizing error-handling logic, you can provide informative and consistent error responses.
Plus, advanced error-handling techniques allow you to catch and handle errors in nested resolvers and test different error scenarios.
