Hello. What method or library are you using to check validation of input values of query and mutation ?🤔

Zod is a nice choice especially if when using typescript

👋 @YeonHoPark Yes, Yup could be an ideal choice, One way that could be done is by creating yup schemas for your inputs and in your resolvers, running 

schema.validate()

 . This will automatically throw the error which will be sent in the GraphQL response.

thank you for answer !!
