graphql-io-utils

Utilities directives to help on graphql input/output validation and sanitization.

Installation

npm i @winninjs/graphql-io-utils

It includes two directives:

1 - stringUtils, which lets you run a method over a string input or output

type Query{
  
  returnTrimmedAndUpper:String! @stringUtils(stringMethods:["trim","toUpperCase"]) # runs trim and toUpperCase on returned String
  
  sendTrimmedAndLower(trimmedAndLower:String!@stringUtils(stringMethods:["trim","toLowerCase"])):String! # runs trim and toLowerCase on query argument

}

2 - validate, runs common validations over input

type Query{
  email(value:String! @validate(email:true)):String! #validates if the value is an valid email
}
