graphql-type-uuid

UUID scalar type for GraphQL.js.

Usage

This package exports a UUID scalar GraphQL.js type:

import GraphQLUUID from 'graphql-type-uuid';

This type can also be imported as follows using CommonJS:

const GraphQLUUID = require('graphql-type-uuid');

GraphQLUUID can represent any UUID version specified in RFC 4122.

Programmatically-constructed schemas

You can use this in a programmatically-constructed schema as with any other scalar type:

import { GraphQLObjectType } from 'graphql';
import GraphQLUUID from 'graphql-type-uuid';

export default new GraphQLObjectType({
  name: 'MyType',
  fields: {
    myField: { type: GraphQLUUID },
  },
});

SDL with graphql-tools

When using the SDL with graphql-tools, define GraphQLUUID as the resolver for the corresponding scalar type in your schema:

import { makeExecutableSchema } from 'graphql-tools';
import GraphQLUUID from 'graphql-type-uuid';

const typeDefs = `
scalar UUID

type MyType {
  myField: UUID
}
`;

const resolvers = {
  UUID: GraphQLUUID,
};

export default makeExecutableSchema({ typeDefs, resolvers });
