Usage

Basic

const GMR = require('@wiicamp/graphql-merge-resolvers'); // Import module

// Demo user resolver
const userResolver = {
  Query: { 
    users: (parent, args, context, info) => ['Hello', 'GraphQL'],
  },
  Mutation: {
    createUser: (parent, args, context, info) => {},
  },

  User: {
    books: (parent, args, context, info) => {},
  }
}

// Demo book resolver
const bookResolver = {
  Query: { 
    books: (parent, args, context, info) => ['Awesome', 'Javascript'],
  },
  Mutation: {
    createBook: (parent, args, context, info) => {},
  },

  Book: {
    postedBy: (parent, args, context, info) => {},
  }
}

// Merge time!!!
const mainResolver = GMR.merge([
  userResolver,
  bookResolver,
]);

console.log(mainResolver);

Now we have new resolver

// console.log(mainResolver);
{
  Query: {
    users: (parent, args, context, info) => ['Hello', 'GraphQL'],
    books: (parent, args, context, info) => ['Awesome', 'Javascript'],
  },
  Mutation: {
    createUser: (parent, args, context, info) => {},
    createBook: (parent, args, context, info) => {},
  },
  User: {
    books: (parent, args, context, info) => {},
  },
  Book: {
    postedBy: (parent, args, context, info) => {},
  },
}
