Example doesn't work

[fennecbutt]

The example in the README doesn't work with the error: Error: Unknown directive "constraint".

As far as I can tell the directive returns its own definition, it shouldn't need to be defined in the graphql schema, right?

I've created a file containing only the js from the readme with the various imports installed, still get this error.

I've just found that this is because of a breaking change in graphql 14 mentioned here: ardatan/graphql-tools#957

Now we have to manually define custom directives in our schema...

I dont know if your problem is exactly like mine, but when working in custom directives for example

extend type Query { me: String! @requireAuth user(userId: ID!): User! users: [User]! }

With the graphql-tools update , the definition of the directive is needed within the schema, something like this

directive @requireAuth on FIELD_DEFINITION

Also i removed the direct dependency of graphql-tools because of the issue you referenced.

Hope this helps.

I've got the same problem

[BrenoMazieiro]

const ConstraintDirective = require('graphql-constraint-directive')
const express = require('express')
const bodyParser = require('body-parser')
const { graphqlExpress } = require('apollo-server-express')
const { makeExecutableSchema } = require('graphql-tools')
const typeDefs = `
  directive @constraint(
    # String constraints
    minLength: Int
    maxLength: Int
    startsWith: String
    endsWith: String
    notContains: String
    pattern: String
    format: String

    # Number constraints
    min: Int
    max: Int
    exclusiveMin: Int
    exclusiveMax: Int
    multipleOf: Int
  ) on INPUT_FIELD_DEFINITION

  type Query {
    books: [Book]
  }
  type Book {
    title: String
  }
  type Mutation {
    createBook(input: BookInput): Book
  }
  input BookInput {
    title: String! @constraint(minLength: 5, format: "email")
  }
  scalar ConstraintString
  scalar ConstraintNumber
`
const schema = makeExecutableSchema({
  typeDefs, schemaDirectives: { constraint: ConstraintDirective }
})
const app = express()

app.use('/graphql', bodyParser.json(), graphqlExpress({ schema }))
