Usage

With promises

const schema = `
  type Person {
    firstname: String!
    lastname: String!
  }

  type Query {
    person(firstname: String!): Person!
  }
`;

const getPerson = function (args, request) {
  return new Promise((resolve) => {
    // args.firstname will be set, request is the hapi request object
    resolve({ firstname: 'billy', lastname: 'jean' });
  });
};

const resolvers = {
  person: getPerson
};

const server = new Hapi.Server();
server.connection();
server.register({ register: Graphi, options: { schema, resolvers } }, (err) => {
  // server is ready to be started
});

With callbacks

const schema = `
  type Person {
    firstname: String!
    lastname: String!
  }

  type Query {
    person(firstname: String!): Person!
  }
`;

const getPerson = function (args, request, cb) {
  cb(null, { firstname: 'billy', lastname: 'jean' });
};

const resolvers = {
  person: getPerson
};

const server = new Hapi.Server();
server.connection();
server.register({ register: Graphi, options: { schema, resolvers } }, (err) => {
  // server is ready to be started
});

• graphiqlPath - HTTP path to serve the GraphiQL UI. Set to '' or false to disable. Default is /graphiql
• schema - graphql schema either as a string or parsed schema object
