Getting error when first starting server in the tutorial

I’m sure it’s something I’m doing wrong, but I’ve just started the tutorial and when I first try to start the server I get

type Launch { ^^^^^^

SyntaxError: Unexpected identifier at new Script (vm.js:74:7) at createScript (vm.js:246:10) at Object.runInThisContext (vm.js:298:10) at Module._compile (internal/modules/cjs/loader.js:657:28) at Object.Module._extensions…js (internal/modules/cjs/loader.js:700:10) at Module.load (internal/modules/cjs/loader.js:599:32) at tryModuleLoad (internal/modules/cjs/loader.js:538:12) at Function.Module._load (internal/modules/cjs/loader.js:530:3) at Module.require (internal/modules/cjs/loader.js:637:17) at require (internal/modules/cjs/helpers.js:20:18) [nodemon] app crashed - waiting for file changes before starting…

My schema.js file is

const { gql } = require('apollo-server');

const typeDefs = gql``

module.exports = typeDefs;


type Launch {
  id: ID!
    site: String
  mission: Mission
  rocket: Rocket
  isBooked: Boolean!
}

type Rocket {
  id: ID!
    name: String
  type: String
}

type User {
  id: ID!
    email: String!
    trips: [Launch]!
}

type Mission {
  name: String
  missionPatch(size: PatchSize): String
}

enum PatchSize {
  SMALL
  LARGE
}

type Mutation {
  # if false, booking trips failed -- check errors
  bookTrips(launchIds: [ID]!): TripUpdateResponse!

    # if false, cancellation failed -- check errors
  cancelTrip(launchId: ID!): TripUpdateResponse!

    login(email: String): String # login token
}

type Query {
  launches: [Launch]!
    launch(id: ID!): Launch
  # Queries for the current user
  me: User
}

and index.js is

const { ApolloServer } = require('apollo-server');
const typeDefs = require('./schema');

const server = new ApolloServer({ typeDefs });

server.listen().then(({ url }) => {
  console.log(`🚀 Server ready at ${url}`);
});

Not sure where the error lies as I was simply copying code from the tutorial…thanks for any clues.

All your graphql code (type, enum, etc) needs to be within the gql template string where typeDefs is defined. I ran into this as well going through the tutorial since it doesn’t mention it.

As per the documentation says (which I also missed the first time):

Our schema will be based on these features. In src/schema.js, import gql from Apollo Server and create a variable called typeDefs for your schema. Your schema will go inside the gql function (between the backticks in this portion: gql``).

Your final file schema.js file should look like this:

const { gql } = require('apollo-server');

const typeDefs = gql`
  type Query {
    launches: [Launch]!
    launch(id: ID!): Launch
    # Queries for the current user
    me: User
  }

  type Mutation {
    # if false, booking trips failed -- check errors
    bookTrips(launchIds: [ID]!): TripUpdateResponse!

    # if false, cancellation failed -- check errors
    cancelTrip(launchId: ID!): TripUpdateResponse!

    login(email: String): String # login token
  }

  type TripUpdateResponse {
    success: Boolean!
    message: String
    launches: [Launch]
  }

  type Launch {
    id: ID!
    site: String
    mission: Mission
    rocket: Rocket
    isBooked: Boolean!
  }

  type Rocket {
    id: ID!
    name: String
    type: String
  }

  type User {
    id: ID!
    email: String!
    trips: [Launch]!
  }

  type Mission {
    name: String
    missionPatch(size: PatchSize): String
  }

  enum PatchSize {
    SMALL
    LARGE
  }  
`;

module.exports = typeDefs;
