WunderGraph Directives Overview

Published: January 05, 2022

Directives are a way of configuring the behaviour of your API straight from the Operation Definition.

Here's an example using two handy directives:

mutation (
$name: String! @fromClaim(name: NAME)
$email: String! @fromClaim(name: EMAIL)
$message: String! @jsonSchema(
pattern: "^[a-zA-Z 0-9]+$"
)
){
createOnepost(data: {message: $message user: {connectOrCreate: {where: {email: $email} create: {email: $email name: $name}}}}){
id
message
user {
id
name
}
}
}

This example uses the @fromClaim directive to inject Claims into the operation. Additionally, it's using the @jsonSchema directive to set a Regex pattern for the $message variable.
